Dust removal in the metallurgical process refers to the dust in the flue gas collected by dust removal equipment (such as electric dust collector, gravity dust collector and bag dust collector, etc.). Electrostatic precipitator and bag dust collector are very common in metallurgical engineering, but with the development of environmental protection requirements, bag dust collector has become a common alternative product in the metallurgical industry.
Bag dust collector, known as filter dust collector, is a dry-type high efficiency dust collector. It makes use of bag filter elements made of fiber fabric to capture the dust in the dust gas of solid particles dust removal device. The principle of bag dust collector is that the dust particles are intercepted when they collide with the fibers due to the inertial force.
The bag dust collector is mainly composed of the upper box, the middle box, the lower box (ash hopper), the ash cleaning system and the exhaust mechanism. The performance of the bag filter is determined by ash cleaning system, in addition to the correct selection of the filter bag material. Therefore, the ash cleaning method is one of the characteristics of the bag dust collector, and it is also an important link of the operation of the bag dust collector.
