Abstract:

Abstract A mathematical model for the rotary dryer that determines the total residence time is developed. Experiments were performed in a laboratory-scale direct contact rotary dryer with the gas flowing concurrently with the solids. The model predictions depicted that the total residence time decreases with increasing the inclination of the rotary drum, the speed of rotation and the radius of rotary drum. The validation of the model was carried out experimentally for maize while varying the inclination of the rotary drum and the speed of rotation. The experimental results were observed to be in good agreement with the model predictions.

Abstract:

A new mathematical model describing heat transfer during the fermentation process in a rotary drum is proposed. The model includes representations of the kinetic reactions, the temperature of the solid bed, and physical structures within the rotary drum. The model is developed using five ordinary differential equations and was then solved using the Runge-Kutta method embedded in MATLAB software. A reasonable behaviour for the temperature profile to the fermentation process is achieved. The results show that the mass of the solid bed, contact heat transfer coefficient, and the wall temperature has a significant effect on the fermentation process in a rotary drum.

Abstract:

Discrete Element Methods have been used extensively in processes involving flow behavior where modeling the individual particles is of particular interest. A rotary cooler is an application of one such process. Although the current analysis can be used to any type of rotary cooler or rotary dryer, this work is focused on the analysis of particles falling from lifters in a planetary rotary cooler used in the production of clinker and installed at the outlet of a rotary kiln. Clinker is the main raw material used to manufacture cement. The objective of this work is to model the particle distribution inside the equipment due to different types of lifters and process conditions. Some of the parameters evaluated demonstrate that the tangential restitution coefficient and the Young’s modulus do not influence the results. However, a rolling friction coefficient on the order of 10-3 is required to represent a real operating condition. The results produce cascading similar to that of experimental observations reported in literature. Both our results and previously reported data display two distinct areas in the rotary drum, one mainly composed of material (the curtain area) and the other lacking material (the air area).

Abstract:

The process of homogenization of particulates is an indispensable part of many industrial processes, and, therefore, it is necessary to pay a special attention to this area and develop it. This paper deals with a complex study of homogenization of particulate matters in a rotary drum in terms of shape, size, and density of particles. In addition, the influence of operating parameters, such as drum filling capacity, rotational speed, and drum filling pattern are also investigated. Studies of reproducibility of discrete element method simulations, effects of rotary drum sizes or effects of drum volumetric filling to the mixture homogeneity index were also carried out. In general, the least satisfactory values of the homogeneity index resulted from the mixing of particles with different densities. The dominating factor of homogenization was the drum filling-up degree. The course of the homogeneity index in 140, 280, and 420 mm drums was very similar and after five revolutions of the drum, identical values of the homogeneity index were achieved for all the drum diameters. The optimal drum filling-up degree is at 40–50% for the spherical particles and 30–40% for the sharp-edged particles. The repeatability of simulations showed the maximum relative standard deviation of the homogeneity index at 0.6% from ten simulation repetitions with the same parametric conditions.

Abstract:

A new type of rotary tubular liquid mixer is proposed in this paper. The tubular rotary drum is rotated with stationary spiral blade fixed inside. The wings are fixed on the blades. The fluid is expelled into the rotary drum and is impinged, separated, flowed around and merged under the effect of centrifugal force and blade hindrance. Then the mixing process is finished. The dimension of mixture structure is reduced, meanwhile the mixture efficiency is enhanced and the mixture effect is strengthened. The practicable turbulent flow in the new rotary tubular liquid mixer is analyzed and the influencing factor is discussed, which provides some proofs for the structural improvement, as well as the selection and optimization of structural parameters.

Abstract:

Different factors can influence the moisture content of product in an organic fertilizer drying process. In this study, biogas volume flow rate and burner temperature were systematically studied in an effort to ascertain their effect on the moisture content of organic fertilizer grain that had been subjected to rotary drum indirect heating procedures. It was found that these two factors did major effect on the moisture content of organic fertilizer in a rotary drum drying process. Additionally, it was also discovered that acceptable organic fertilizer moisture content occurred when the rotary drum drier utilized both the biogas volume flow rate of 0.058 m3/min. in combination with the drying temperature of 500°C while the percentage of biogas blower and burner operation were reduced by 22.67 % and 9.1%, respectively.

Abstract:

Biosolids Drying is the process of producing a fertilizer product for beneficial reuse from solids produced during municipal wastewater treatment. The drying of biosolids involves the evaporation of water to stabilize the material and produce a product for beneficial use. Thermal energy needs to be transferred to the biosolids to evaporate the water and heat the solids. Energy can be provided by combustion of fuels, re-use of waste heat or solar radiation (WEF, 2014). The most common technology for biosolids drying in the United States utilizes rotary drum dryers. In these systems, fines and crushed oversized pellets produced during the drying system are mixed with dewatered biosolids upstream of the dryer to create a 55% - 65% dry biosolid in the form of pellets. Reducing the percentage of fines generated during the drying process can potentially reduce the amount of energy required for drying. In earlier research completed by Zhang (2018) it was shown that energy modifying amendments, specifically cationic polyelectrolytes, can reduce the zeta potential of biosolids in solution and possibly promote aggregation of the fines. One of the tested amendments, polydiallyldimethylammonium chloride (PDADMAC), was also shown to increase the particle size of the biosolids in solution. In this work, a bench scale drying system was designed and developed to apply the polyelectrolyte amendments to biosolids during the mixing phase, and to gauge the impact on the pellet size distribution and the percentage of fines generated after drying. It was shown that PDADMAC, which is a high charge density cationic polyelectrolyte, had a measurable, though inconsistent, impact on pellet size when applied during the mixing phase. This work also highlights the varying characteristics of biosolids and the recycled biosolids produced during the drying process. Both PDADMAC, and polyallyamine, another cationic polyelectrolyte, when applied to biosolids during the mixing phase limited the increase in fines production as the mixing time was increased prior to drying.

Abstract:

In 2006 resin accounted for approximately 17% of the direct manufacturing costs for oriented strand board (OSB). Because of their increased dependency on pMDI-resins, this percentage is likely greater for oriented strand lumber (OSL) and laminated strand lumber (LSL). The cost of PF- and pMDI-resins is expected to face upward pressure as the cost of their primary constituents, natural gas and crude oil, continue to reach new highs. Therefore, there is strong economic incentive to optimize the use of resin in the production of these three products. This can be accomplished by addressing two key issues: reducing resin wastage and optimizing resin distribution on the strands. Both issues will be overcome by focusing on the blending process, where resin is applied to the strands. This work focused on development and use of a discrete element model (DEM) for simulating strand flow in a rotary drum blender using the EDEM software package. EDEM required the input of three material and three interaction properties. Development of the model involved creating the simulated environment (i.e. physical dimensions) and assigning appropriate material and interaction properties given this environment and the assumptions that were made. This was accomplished in two steps, completing baseline bench-top experiments and a literature review to determine appropriate parameters and initial value ranges for these properties, and then fine-tuning these values based on a validation process. Using the validated model, an exploratory study was conducted to determine the effect of four blender design and operating parameters (flight height, number of flights, blender rotational speed, and blender fill level) on bulk strand flow. The results were analyzed with regards to overall trends and by focusing on two perspectives, end users and blender manufacturers. It was found that there was a strong relationship between these key parameters and bulk strand flow. These results suggest that operating parameters of a blender, namely rotational speed and tilt angle, should be linked directly to the blender feed rate to ensure an optimal blending environment is maintained. In addition, manufacturers of blenders must take into consideration the range in final operating conditions when designing and positioning flights.

Abstract:

A conversão biológica de biomassa celulósica em combustíveis e produtos químicos oferece elevados rendimentos de produtos para a o sucesso da economia e futuramente o potencial de custos muito baixos. A hidrólise enzimática, que converte a biomassa lignocelulósica a açúcares fermentáveis é uma etapa complexa do processo. Um requisito importante no custo-eficiente no processamento de biomassa lignocelulósica é empregar um reator que assegure, ou até mesmo promova uma elevada conversão de celulose para glicose com uma mínima dosagem de enzima. O objetivo da utilização do reator é também de processar um elevado teor de matéria seca e, consequentemente, elevados níveis de celulose que conduzem a um aumento na concentração do produto. No entanto, nos processos que empregam altas cargas de sólidos, além da viscosidade elevada do meio reacional, outros fatores afetam o processo, além da inibição do produto, sendo estes as limitações decorrentes da transferência de massa e a agitação e mistura do meio. Dentro deste contexto, o objetivo deste trabalho foi projetar um biorreator do tipo tambor rotativo para ser empregado no processo, em grande escala, de hidrólise enzimática do bagaço de cana-de-açúcar. Para alcançar este objetivo foram realizados experimentos, em escala de bancada, em um protótipo já existente no laboratório. Neste equipamento foi adicionado uma carga de sólidos de 10% (p/v) (bagaço de cana de açúcar, in natura e pré-tratado) e enzima celulase (Accellerase 1500® (Danisco)). Os resultados dos experimentos no reator mostraram um aumento na concentração de glicose (L⁻¹) convertida quando comparado com os realizados em frascos Erlenmeyer (controle). Isto ocorreu devido a melhor transferência de massa e de mistura no reator, sendo este mais eficiente, pois permite uma maior área de contacto da enzima com o substrato (bagaço).
The biological conversion of cellulosic biomass to fuels and chemicals offers high yields of products for the success of the economy and future the potential for very low costs. Enzymatic hydrolysis that converts fermentable sugars in lignocellulosic biomass is a complex step in this process. An important requirement in cost-efficient in the processing of lignocellulosic biomass is to employ a reactor that will ensure, or even promote, maximal conversion of cellulose to glucose with a minimum dosage of enzyme. The purpose of using the reactor is also for to process of high dry matter contents and therefore higher levels of cellulose that will also drive up the product concentration. However, the processes that emply high solid loadings, in addition to the high viscosity of the reaction mixture and other factors than product inhibition, notably mixing and mass transfer limitations. Within this context, the aim of this work was to design a bioreactor rotary drum to be used in the process, with largescale enzymatic hydrolysis from sugarcane bagasse. To achieve this objective were performed in a bench scale, with prototype already existing in the laboratory. In this equipment was added a solids loading of 10% (w/v) (sugar cane bagasse, raw and pretreated) and cellulose enzyme (Accellerase 1500® (Danisco)). The results of the reactor experiments showed an increase in glucose concentration (L⁻¹) converted when compared with those realized in Erlenmeyer flasks (control). This occurred because the mass transfer and mixing in the reactor is more efficient because it allows greater contact area of the enzyme with the substrate (sugarcane bagasse).

Abstract:

La problématique de l’homogénéité de traitement mécanique et thermique d’un lit particulaire bi-disperse en tailles ou en densités dans un tambour tournant horizontal a été abordée. Dans la première partie, le mélange des billes sphériques millimétriques dans un tambour de type ‘tranche’ a été observé expérimentalement à l’aide des maquettes originales et simulé numériquement à l’aide d’un code commercial de type DEM. En ajustant le coefficient de frottement entre les billes, un accord satisfaisant a été obtenu entre les résultats des simulations et des expériences. Le lit a été globalement caractérisé par l’indice de ségrégation radial, la répartition des billes dans la couche frontale et l’angle de talus dynamique. Des phénomènes importants de ségrégation radiale et axiale ont été mis en évidence. Une réduction très significative de l’indice de ségrégation radiale a été obtenue dans le cas des ailettes multiples et longues par rapport au cas avec peu d’ailettes courtes ou pas d’ailettes. Dans la deuxième partie, le chauffage des billes par contact avec la paroi périphérique du tambour a été simulé par la méthode DEM. Des lits mono-disperse, bi-disperse (comme dans la partie 1), et à dispersion gaussienne ont été considérés. Les indices de ségrégation mécanique et thermique ont été comparés pour les différents types de lits et différentes configurations d’ailettes. L’intensité de la ségrégation thermique a été renforcée, dans l’ensemble, par la ségrégation mécanique et a été la plus forte pour le lit bi-disperses en densités. L’augmentation de la hauteur et du nombre des ailettes a considérablement amélioré l’homogénéité thermique du lit et la vitesse globale de chauffage
Product homogeneity issue during mechanical and thermal processing of a bi-dispersed bed with two particles’ sizes or two particles’ densities in a horizontal rotary drum was considered. In the first part, the mixing of milli-metric size spherical beads in a two-dimensional drum was simulated by means of a commercial discrete element software and optically observed in a specially designed laboratory scale device. The spatial distribution of the particles in the front bed section, the radial mechanical segregation index and the dynamic slope angle were analyzed. After adjusting the friction coefficient, the simulation results were close to the experimental ones. Important phenomena of radial and axial segregation have been highlighted. The radial segregation index was found to be significantly decreased by applying an important number of long baffles, while using few short baffles had practically no influence on segregation intensity. In the second part, the heating of the bed of spherical beads in a 2D drum with hot peripheral wall was simulated by means of the discrete element software. Mono-dispersed, gaussian-dispersed and bi-dispersed beds (same as in part 1) were considered. The mechanical segregation and the thermal segregation indexes were calculated for the different types of bed and for different baffles configurations. The thermal segregation was found to be generally enhanced by the mechanical segregation and reached its highest values for the bi-density bed. Increasing the number and the length of the baffles considerably improved the overall heating rate and the thermal homogeneity of the considered beds

Abstract:

The paper presents the conceptual design, modeling and prototyping of a novel rotary motor based on shape memory alloy (SMA) wires. The basic architecture of the device capitalizes on a SMA wire wound around a low-friction cylindrical drum. The backup force to the SMA wire is provided by a beam spring which generates a nearly-constant force tangential to the drum. The electrical activation of the wire produces a contraction of the wire, hence a rotation of the drum fitted to the shaft through an overrunning clutch (free wheel). Thanks to the overrunning clutch, during the backup phase (recoiling of the wire), the drum rotates backward while the shaft does not move. Spurious backward movements of the shaft are contrasted by a second overrunning clutch linking the shaft to the frame. The paper presents a model for the quasi-static simulation of the motor and the experimental characterization of a prototype device featuring three active drums, a rotary sensor and an angular brake to apply the external load.

Abstract:

The paper presents the analytical model of a linear/rotary solid-state actuator formed by a shape memory wire wound over a cylindrical drum. The model assumes a bilinear stress-strain behaviour of the wire in the martensitic state (low temperature) and a linear elastic response in the austenitic state (high temperature). Based on simple equilibrium conditions, the model calculates the stress and strain distributions in the wire subjected to a constant backup force and to frictional sliding forces at the contact with the drum. Closed-form expressions are supplied for the stroke produced by whatever actuator geometry. The model shows that large strokes (up to one half of the drum diameter) are achieved if the frictional coefficient is kept below 0.01. Rolling-contact architectures or sonic-pulse excitation of the drum are discussed as technical solutions to obtain such low friction values.

Abstract:

Haptic interfaces require lightweight, small actuators with high force capability and low friction. In this paper, based on the structure of conventional shear mode disc and drum type MR fluid dampers, a lightweight continuous rotary MR damper working in valve mode is designed for haptic interfaces. The proposed design is compared to shear mode disc-type and drum-type designs with similar torque–to–mass ratio via computer simulations. Mathematical models for the resistant torques of both the shear mode and the valve mode are derived. Subsequently, the finite element analysis of electromagnetic circuit calculations was carried out by FEMM software to perform an optimization of the dimensions of the parts such as gap size and thickness. It is shown that the proposed continuous rotary valve mode MR damper is a fine candidate that meets the requirements of haptic interfaces.

Abstract:

An attractive but little explored field of application of the shape memory technology is the area of rotary actuators, in particular for generating endless motion. This paper presents a miniature rotary motor based on SMA wires and overrunning clutches which produces high output torque and unlimited rotation. The concept features a SMA wire tightly wound around a low-friction cylindrical drum to convert wire strains into large rotations within a compact package. The seesaw motion of the drum ensuing from repeated contraction-elongation cycles of the wire is converted into unidirectional motion of the output shaft by an overrunning clutch fitted between drum and shaft. Following a design process developed in a former paper, a six-stage prototype with size envelope of 48×22×30 mm is built and tested. Diverse supply strategy are implemented to optimize either the output torque or the speed regularity of the motor with the following results: maximum torque = 20 Nmm; specific torque = 6.31×10−4 Nmm/mm3; rotation per module = 15 deg; free continuous speed = 4 rpm.
