central machinery industrial dust collector has appeared in Japan and some European and American countries as early as the 1970s. It has the advantages of small size, high efficiency, low investment and easy maintenance. However, due to its small volume, it is difficult to combine large air volume equipment, low filtering wind speed and narrow application range, and it is only used in grain, welding and other industries, so it has not been widely promoted for many years. In recent years, with the continuous development of new technologies and materials, represented by Dazhi Co., Ltd. of Japan, Thomson Company of the United States, and Biwei Company, the structure and filter materials of the dust remover have been improved, making the filter cartridge dust remover widely used in cement, steel, power, food, metallurgy, chemical industry and other industrial fields. The overall capacity has increased several times, becoming a large dust remover (GB6719-86) with a filtering area of 2000m, It is a * scheme to solve the problem of difficult collection of ultra-fine dust by traditional dust collectors, high filtering wind speed, poor dust removal effect, easy wear and tear of filter bags, and high operating cost. Compared with the existing bag type and electrostatic precipitators on the market, it has the characteristics of large effective filtering area, low pressure difference, low emission, small size, and long service life, and has become a new direction for the development of industrial dust collectors.

Structure of central machinery industrial dust collector

The structure of central machinery industrial dust collector is composed of air inlet pipe, exhaust pipe, box, ash hopper, ash cleaning device, guiding device, air flow device, air flow distribution plate, filter cartridge and electric control device, similar to the air box pulse bag dedusting structure. The arrangement of the filter cartridge in the dust remover is very important. It can be vertically arranged on the box pattern board or obliquely arranged on the pattern board. From the ash removal effect, the vertical arrangement is more reasonable. The lower part of the flower plate is a filter chamber, and the upper part is an air box pulse type. Air flow distribution plate is installed at the inlet of the dust remover.
