滤筒除尘设备的作业流程：
Operation process of filter drum dedusting equipment:
含尘气体进入除尘设备灰斗后，因为气流断面俄然扩展，气流中一有些颗料粗大的尘粒在重力和惯性力作用下沉降下来；粒度细、密度小的尘粒进入过滤室后，通过布朗涣散和筛滤等概括效应，使粉尘沉积在滤料表面，净化后的气体透过滤筒进入上箱体的净气腔并集合至出风口排出。
After the dust containing gas enters the dust hopper of the dedusting equipment, because the cross section of the air flow expands suddenly, some coarse dust particles in the air flow settle under the action of gravity and inertia force; after the dust particles with fine particle size and small density enter the filter chamber, the dust is deposited on the surface of the filter material through the general effect of Brownian laxity and screening, and the purified gas enters the clean air cavity of the upper box body through the filter cylinder and Collect to the air outlet for discharge.
滤筒除尘设备的阻力随滤料表面粉尘层厚度的增加而增大。阻力抵达某一规定值时，进行清灰。为了保证系统的正常作业，除尘设备阻力的上限应维持在1400～1600Pa规模内，当逾越此约束规模，焊烟除尘设备，应由PLC脉冲自动控制器通过定阻或守时宣告指令，进行三情况清灰。最后灰斗内收集的粉尘通过卸灰阀，连续排出。
The resistance of the filter dust collector increases with the increase of the thickness of the dust layer on the surface of the filter material. When the resistance reaches a specified value, clean the ash. In order to ensure the normal operation of the system, the upper limit of the resistance of the dedusting equipment shall be maintained within the scale of 1400-1600pa. When exceeding this constraint scale, the welding fume dedusting equipment shall be cleared by the PLC pulse automatic controller through the constant resistance or punctuality declaration instruction. Finally, the dust collected in the ash hopper is discharged continuously through the ash unloading valve.
