Analysis on the requirements of bag and frame making of bag type dedusting equipment

　　For bag filter, the bag is its core component. The bag quality of the precipitator directly affects the removal efficiency of the precipitator, and the life of the filter bag directly affects the operation cost of the bag precipitator.

　　Therefore, according to the operation environment and medium conditions of the dust remover, we choose polyester needle felt with temperature resistance of 80-120 ℃ and unit weight of 500-550g / m3.

　　The bottom of the bag is sewed with a layer of binding, no burr is exposed, the bottom is made of reinforced ring cloth, the filter bag is reasonably cut, and the seam is minimized.

　　At the splicing position, the overlapping lap width shall not be less than 10 mm, so as to improve the strength and scouring resistance of the filter bag.

　　At the same time, the distance between the bottom of the filter bag and the air inlet, the design of the air inlet and diversion system of the equipment have a great relationship with the service life of the filter material.

　　The upper end of the filter bag adopts the form of spring expansion ring, with good sealing performance, high installation reliability and quick bag change. Only 1-2 people can change the bag through the lift top cover. The device of the filter bag is put into and taken out in the clean air chamber without entering the filter chamber of the dust remover.
