除尘设备原理 Industrial dust collector , principle of dust removal equipment
越来越多的企业使用工业除尘器来治理工业生产中所产生的粉尘问题.一般除尘原理是含尘气体由除尘器进气总管通过进气支管的风量调节阀，均匀地分布到各单元滤袋室，由于气流断面的实然扩大或导流板的作用，气流中一部分大颗粒粉尘因惯性而落入灰斗，颗粒小的粉尘通过筛分，惯性，粘附，扩散和静电等作用被作用被阻留在滤袋外侧，净化信任感的气体则进入袋内，汇集到净气室，经排气管排出。 Now, with the rapid development of industrialization , more and more enterprises use industrial dust collectors to deal with dust problems in industrial production . The general principle of dust removal is that the dust-containing gas is adjusted by the air inlet of the dust collector through the air inlet branch pipe. The valve is evenly distributed to each unit's filter bag room. Due to the actual expansion of the air flow section or the role of the deflector, some large particles of dust in the air flow fall into the ash hopper due to inertia, and small particles of dust pass through the screen and inertia Adhesion, diffusion, and static electricity are blocked on the outside of the filter bag, and the gas purifying the confidence enters the bag, collects it in the clean room, and is discharged through the exhaust pipe. With the continuous filtering, dust particles gradually form a dust layer on the surface of the filter bag due to the effects of adhesion and retention. With the continuous increase of dust on the surface of the filter bag, the resistance of the filter bag increases. When the pressure difference in the filter bag room reaches the set value or runs for a set time, the controller sends a signal to lift the valve to close the drain of the unit's filter bag room. The air port keeps the room offline. At this time, the compressed air is injected into the filter bag of the unit's filter bag chamber from the nozzle on the blowing pipe through the pulse valve through the pulse valve for group injection. After the blowing is completed, the poppet valve is opened, and the filter bag is restored to the filtering state. Similarly, the filter bag chambers of the other units are controlled by the program controller to perform the above-mentioned blowing cycle in order to achieve the purpose of dust removal. Finally, the dust falling from the ash bucket due to the expansion of the filter bag and the reverse acceleration is sent away by the ash conveying device.
