Abstract:

A cyclone separator holds significant importance as the primary gas–solid separation apparatus in the industrial sector. Cyclone separators operate based on a fundamental principle, primarily harnessing the centrifugal force produced by the rotation of air in order to segregate solid particles from the gas stream and then collect them. In addition to the main vortex in the flow field, there are a number of secondary flows, which significantly impact the aggregation of fine particles and contribute to the heightened energy consumption.

Abstract:

Gas cyclone separators are widely used in industrial processes for separation of dust from gas streams or for product recovery. Their design normally has tangential entrance inlets and the cyclones are defined as funnel-shaped industrial inertial devices. Cyclones are particularly well suited for high temperature and pressure conditions because of their rugged design and ﬂexible components materials. Cyclone collection efﬁciencies can reach 99% for particles bigger than 5 μm, and can be operated at very high dust loading. One of the aims of this research was simulate, through computational flu

In many industries, energy auditing is important as the basis for controlling processes and designing additional equipment or modifying an existing plant. However, it requires detailed data of the materials flow, which often cannot be determined easily by direct measurement due to high-temperature limitations. This paper presents the second part of an integrated study to perform energy auditing in a separate line and in-line calciners (SLC-I) type cement plant. The second part of this study, as presented in this paper, focused on the materials flow calculation for eight separate cyclones and t

Abstract:

In developing countries cassava starch is produced mostly rurally using artisan methods through wet-way processes that consume as much as 37 m³ of water per processed ton. In comparison, the little industrial production consumes 5 m³ of water per processed ton. These waste waters, highly contaminated, are usually discharged in to the rivers without any treatment. With the aim of industrializing the cassava flour production, CIAT and CLAYUCA are developing an alternative dry technology, environmentally sustainable, to produce enriched flour as a starch substitute. The intention is to separate t

Abstract:

Cyclone separators are commonly employed in the mining, metallurgy and chemical industries due to their simple structure, easy maintenance and high recovery efficiency. However, with the wide application of cyclone separators, many problems have become exposed in their practical operation, restricting their development. Among these, wall erosion is becoming a significant problem. In this study, to resolve the problem of severe erosion on the walls, the Eulerian–Lagrangian framework was employed to investigate a cyclone separator with a draft plate at the inlet and to evaluate the effect of a d

Purpose The purpose of this paper is to explore and analyse the critical success factors (CSFs) of humanitarian supply chains in mitigating the impact of cyclones in the Indian context using the fuzzy Decision-Making Trial and Evaluation Laboratory (DEMATEL) approach. Design/methodology/approach The selection of CSFs of humanitarian supply chains has been done through several secondary sources and discussion with 12 disaster experts. Thereafter, DEMATEL, an expert judgement-based technique, has been used for selecting, building and analysing a structural model that involves causal relationship

Abstract In the present investigation a cylindrical electrostatic precipitator was built into a cyclone's outlet tubes, and was tested at various dusts and voltages. It has been found that the penetration (the unremoved fraction of the dust) for the airborne particles (d < 10 mm) in the case of working built in electrostatic precipitator, decreased to 5–10% of the penetration of the (only) mechanical cyclone operation. The penetration data is given at various dusts and voltages. All are proving that the method is working satisfactorily. If the voltage was smaller than the on set voltage of

Abstract:

Addition is the most frequent floating point operation in modern microprocessors. The design of floating point addition is relatively complex than other flotation point arithmetic operations. Due to its complex shift-add-shift-round data flow, floating point addition can have a long latency. This paper has shown an efficient implementation of addition module on a reconfigurable platform cyclone IV EP4CE15, which is both area as well as performance optimal. The proposed design has optimized the individual complex components of adder module (like dynamic shifter, leading one detector (LOD), prio

Abstract:

The article covers the results of an analytical review of technology and technical means for cleaning dust-laden air released during the cleaning of raw cotton by the UHK cleaning unit; the air is taken into cyclones using an aspiration system including pneumatic lines, a fan and a conical cyclone. As a result, the drawbacks of the existing aspiration system for UHK cleaning units were identified; it was determined that the efficiency of the aspiration system for cotton cleaning units largely depends on the correctly chosen design of the diffuser, in which part of the dynamic pressure is conve
