CNMC type countercurrent pulse back blowing bag filter

　　CNMC type counter current pulse back blowing bag filter is a new type of pulse bag filter improved by digestion with new equipment and technology imported from abroad. The utility model has the advantages of large processing air volume, high purification efficiency, small floor area, small abrasion of filter bags, long service life, simple replacement of filter bags, convenient maintenance, etc.

　　The CNMC type counter current pulse back blowing bag dust remover adopts the pulse type counter current back blowing dust remover, and its electrical control adopts the sequential controller with reliable performance, which can be widely applied to the purification and recycling of dust-bearing gas at room temperature and high temperature in industrial and mining enterprises such as metallurgy, chemical industry, machinery, non-ferrous casting, mining, asphalt concrete industry, cement, power, carbon black, grain processing, etc In recent years, the equipment has been widely used in many provinces and cities in China, and has been widely welcomed by users.

　　Features of CNMC type countercurrent pulse back blowing bag filter:

　　1. The equipment adopts pulse back blowing cleaning method, which is one of the best cleaning effect in our country. The upper box of the equipment is divided into 18 chambers which are not connected with each other, and is connected with a long venturi tube. The purpose of ash cleaning is achieved by using program-controlled pulse. The small Venturi tube at the upper end of the blowing tube and the filter bag is cancelled in structure, which is simple in structure and convenient in operation and maintenance.

　　2. Compared with other domestic precipitators, the equipment has the characteristics of large air volume and small system resistance, and has a wide range of application. (purification and recovery of mixed gas with dust concentration less than 60g / m3 at room temperature and high temperature)

　　3. The flower plate edge of the separating upper middle box body is pressed into a conical hole to form a smooth contact with the filter bag, which has good sealing performance and reduces the wear of the hole edge and the filter bag.

　　4. Simple and reasonable structure, small floor area, can be installed indoors and outdoors. Users can choose their own model or parallel combination according to their production process and treatment air volume, and can provide carbon steel or stainless steel dust remover as required.

　　Working principle of CNMC type countercurrent pulse back blowing bag filter:

　　The dust containing gas enters the bag filter from the air inlet and filters through the outer surface of the bag. The purified gas flows from the inside of the bag to the upper chambers and is discharged from the air outlet through the long venturi tube. When the dust adsorbed on the outer surface of the filter bag reaches the value, the program controls the timing of pulse injection, that is, the high-pressure air is injected into the long venturi tube and the purified gas is blown back into the filter bag at the same time, forming a large pressure difference, and the dust is cleaned down to achieve the goal of dust removal, and the resistance of the whole equipment and system is kept stable, and the dust blown back falls to the bottom of the lower box The part is discharged and recycled by screw conveyor.
