The Dust Movement Regular Pattern And The Key Control Technology Research Of The Washery

Heidaigou coal preparation plant, which puts into production, have carried out a series of governance. It emphasis on the census carried out dust, environmental testing and breakdown of governance, proposed "blocking, settlement, rinsing, removing, emission". Technical measures (such as comprehensive) have accumulated a wealth of management experience and technical reserves. A part of the treatment technology has been implemented, and received a preliminary treatment results.The dust of the coal washery conducted further study on the reproduced point of dust production. The mechanism is analyzed and put forward voltage drop-induced. The shock wave is produced wind power source for the theory of dust; According to different points of production characteristics and structural characteristics of dust, the reproduced point made feasible options for dust control. Wuxi Power Machinery Co. Ltd. Film products LFD flat bag filter dust collector is selected as the filter. It has analysis the dust skirt plate closure mechanism and obtained the Trough in The Merry, pressure distribution characteristics. It has demonstrated the advantage of the guided trough, precipitator dust mechanism and superiority. According to different points of production characteristics and structural features of dust, the research has raised a suitable dust control programs, and through numerical simulation, decided to set the optimal trough coupled with precipitator program.The project bases on the practical data analysis of dust control according to the national requirements of the concentration of dust control standards. In a theoretical point, the purpose of the project is to build the capacity of dust emission mechanism, oven laws and control technology. Those data helps the implementation of a comprehensive dust control technology to provide strong guidance favorable, while the implementation of comprehensive management techniques also play a role in testing and evaluation. The implementation of project is a economic, rational and efficient dust control program and equipment. The implementation of technology research and engineering is the perfect combination, and ultimately solve the coal preparation plant Heidaigou dust pollution.
