Operating principle of dust extraction equipment in dust workshop


Dust workshop vacuum equipment is used to deal with the problem of dust pollution in the workshop. It is widely used in mining, woodworking, furniture factory, machinery hardware factory, pharmaceutical chemical factory, quarry factory, manual welding workshop and other industries. What is the principle of dust workshop vacuum equipment operation ? ?

 

The working principle of dust extraction equipment in dust workshop is as follows:

 

The dust-laden gas enters each device from the air inlet through the lower part of the middle box. Due to the principles of inertial collision and natural settlement, large particles of dust fall directly under the ash hopper. In the material area, the dust is isolated and adsorbed on the outer surface of the filter bag. The filtered clean gas enters the upper case through the center of the filter bag and is discharged from the exhaust pipe on the fan!


    粉尘车间吸尘设备继续运行 ,滤 隔离 的粉尘不 停的 增加,从而 使 除尘器本身的阻力也逐渐升高,滤袋表面附积的粉尘达到一定量时,清灰控制装置发出信号,先令一个袋室的提升阀关闭切断该室的过滤气流,然后打开电磁脉冲阀,压缩空气由储气罐经气包以短促的时间顺序通过各个脉冲阀经喷吹管上的喷嘴诱导数倍于喷射气量的空气进入滤袋,形成空气波,使滤袋由袋口至底部产生急剧的膨胀和冲击振动,再加上逆气流的作用,使滤袋外侧所附积的粉尘脱落。 As the dust extraction equipment in the dust workshop continues to operate , the dust isolated by the outer layer of the filter material increases continuously , so that the resistance of the dust collector itself also gradually increases. When the dust accumulated on the surface of the filter bag reaches a certain amount, the dust removal control The device sends a signal. First, the poppet valve of a bag chamber is closed to cut off the filtered air flow in the chamber, and then the electromagnetic pulse valve is opened. The compressed air passes from the gas storage tank through the air bag through each pulse valve in a short time through the nozzle on the blow pipe. Induces several times the volume of jet air into the filter bag, forming air waves, causing the filter bag to have a rapid expansion and shock vibration from the mouth of the bag to the bottom, plus the effect of reverse airflow, which causes the dust accumulated on the outside of the filter bag to fall off. . The bag pulse bag type dust collector is composed of a plurality of independent chambers. During the cleaning of the dust, each chamber is performed in sequence without interference with each other, and realizes long-term continuous operation .
