The multi station welding smoke purifier system in the workshop is designed according to the site, and the process flow of the multi station welding smoke purifier is based on the layout of the welding positions in the workshop. Each welding position is separated by a partition into a small space of 2 meters. A conical smoke exhaust hood is installed at the top, and a 7-shaped 400mmx400mm white iron pipe is laid 3.5 meters above the welding position. The pipe hook and strand are each 12 meters long. One is fixed on the room column in the east-west direction, and the other is fixed with a door shaped bracket in the north-south direction. According to the opening of the welding position, a flexible arm with a diameter of 160mm is used to connect the smoke exhaust hood. The flexible arm is used for smoke and dust capture. A medium pressure, 10000m3/h (left and right) variable frequency centrifugal fan is connected through the pipe, and 600mm in front of the fan inlet is Set up a cross-sectional plug for adjusting the air volume, and automatically convert the motor frequency according to the adjusted air volume. The outlet pipeline of the fan is a square tube or cylinder with a diameter of 600mm. The smoke and dust generated during welding are captured by a flexible arm and enter the pipeline. After being treated by a centrifugal fan, the smoke and dust meet the standard and are discharged outside. The height of the exhaust chimney is 500mm higher than the height of the building. This solution requires minimal one-time investment and simple daily maintenance. By using a variable frequency motor, it solves the problem of high energy consumption.

本设备在系统主风机的作用下， 含尘气体从除尘器上部的进风口进入除尘器底部的气箱内进行含尘气体的预处理， 然后从底部进入到上箱体的各除尘室内； 粒度细、 密度小的尘粒进入滤尘室后，通过布朗扩散和筛滤等组合效应，使粉尘吸附在滤料的外表面上，过滤后的干净气体透过滤筒进入上箱体的净气室由排气管经风机汇集至出风口排出。

Under the action of the main fan in the system, the dust containing gas enters the gas box at the bottom of the dust collector from the inlet at the top of the dust collector for pre-treatment, and then enters each dust removal chamber in the upper box from the bottom; After the dust particles with fine particle size and low density enter the dust filtering chamber, they are adsorbed on the outer surface of the filter material through a combination of Brownian diffusion and screening effects. The filtered clean gas enters the clean air chamber of the upper box through the filter cartridge and is collected by the exhaust pipe through the fan and discharged from the air outlet.

随着过滤工况持续，积聚在滤筒外表面上的粉尘将越积越多，相应就会增加设备的运行阻力，阻力随滤料表面粉尘层厚度的增加而增大。为了保证系统的正常运行，除尘器阻力的上限应维持在 1400～1600Pa 范围内，当超过此限定范围，应由 PLC 脉冲自动控制器通过定阻或定时发出指令进行清灰。

As the filtration process continues, more and more dust will accumulate on the outer surface of the filter cartridge, which will correspondingly increase the operating resistance of the equipment. The resistance increases with the thickness of the dust layer on the surface of the filter material. In order to ensure the normal operation of the system, the upper limit of the dust collector resistance should be maintained within the range of 1400-1600Pa. When this limit is exceeded, the PLC pulse automatic controller should issue instructions for dust cleaning through fixed resistance or timing.

该滤筒除尘器的清灰过程是脉冲控制仪控制脉冲阀的启闭。当脉冲阀开启时，气包内的压缩空气通过脉冲阀经喷吹管上的小孔喷射处一股高速、高压的引射气流，从而形成一股相当于引射气流体积 1～2 倍的诱导缺陷流，一同进入滤筒内，使滤筒内出现瞬间正压并产生鼓胀和微动；沉积在滤料上的粉尘脱落，掉入灰斗内，灰斗内的粉尘通过卸灰阀，连续排出。如此逐序循环清灰，此清灰方式不但、还避免了喷吹清灰产生的粉尘二次吸附。

The cleaning process of the filter cartridge dust collector is controlled by a pulse controller to open and close the pulse valve. When the pulse valve is opened, the compressed air in the air bag is sprayed through the small hole on the spray pipe by the pulse valve, forming a high-speed and high-pressure injection airflow, thereby forming an induced defect flow equivalent to 1-2 times the volume of the injection airflow, which enters the filter cartridge together, causing instantaneous positive pressure and bulging and micro motion in the filter cartridge; The dust deposited on the filter material falls off and falls into the ash hopper. The dust in the ash hopper is continuously discharged through the ash discharge valve. This sequential cleaning method not only avoids the secondary adsorption of dust generated by blowing and cleaning, but also eliminates the need for dust removal.
