Parameters Affecting Dust Collector Efficiency for Pneumatic Conveying: A Review

Abstract

In a context of energy abundance for industrial applications, industrial systems are exploited with minimal attention to their actual energy consumption requirements to meet the loads imposed on them. As a result, most of them are used at maximal capacity, regardless of the varying operational conditions. First, the paper studies pneumatic conveying systems and thoroughly reviews previously published work. Then, we overview simulations and operating data of the experimental parameters and their effects on the flow characteristics and transport efficiency. Finally, we summarize with a conclusion and some suggestions for further work. The primary goal of this study is to identify the parameters that influence the energy consumption of industrial dust collector systems. It is differentiated from previously published overviews by being concentrated on wood particles collection systems. The results will permit a better selection of an appropriate methodology or solution for reducing an industrial system’s power requirements and energy consumption through more precise control. The anticipated benefits are not only on power requirement and energy consumption but also in reducing greenhouse gas emissions. This aspect shows more impacts in regions that rely on electricity supplied by thermal power stations, especially those that use petrol or coal.

Experimental Investigation of Possibilities to Improve Filtration Efficiency of Tangential Inlet Return Cyclones by Modification of Their Design

“…It has been found that the optimal ratio of inlet width to inlet height b/a is in the range of 0.25-0.5 [53,54], although the authors of [59] report a different range from 0.5 to 0.7 Therefore, a lot of work has been undertaken on the organization of the aerosol inlet into the cyclone. The authors of the work [51][52][53][54][55][56][57][58][59][60][61][62][63][64] believe that replacing one inlet channel with several inlet channels will improve the cyclone efficiency. Reference [61] presents a comparative analysis of the original cyclone (one inlet channel) with the designs of two cyclones that are equipped with four equal inlet channels.…”

“…The use of high velocities generates high pressure drop. According to the study of the author of [60], the cyclone inlet velocity reaches υ 0 = 35 m/s, but the pressure drop also reaches a large (about 4 kPa) value.…”

Energy Efficiency and Industry 4.0 in Wood Industry: A Review and Comparison to Other Industries

“…Like drying, the dust collection system is one of the most energyintensive industrial processes, especially for the second and the third transformation. The energy efficiency approach can be applied to dust collection by improving the mechanical and electrical installation and adopting an energy management system [94]. Based on Industry 4.0, Beaulac et al explain in detail the different ways to improve energy efficiency in the case of cyclone dust collectors.…”

Study on the Influence of Different Factors on Pneumatic Conveying in Horizontal Pipe

“…In the conveying process, the energy consumption is high, and the materials are also easy to break, which affects the economy of enterprises. Therefore, scholars are required to find scientific and reasonable design methods to develop pneumatic conveying systems suitable for particle materials with low energy consumption and high efficiency [15][16][17][18]. At the early stage of the development of pneumatic conveying technology, Cornish and Pinkus Oscar [19,20] and others studied the pressure drop in the pipe of pneumatic conveying.…”
