Industrial workshop dust removal system, welding smoke dust removal, welding smoke purification equipment, electric welding machine welding smoke purifier, large welding smoke purifier, welding workshop produces a large amount of welding smoke during welding and processing of workpieces. A small amount of dust in the welding smoke needs to be purified before it can be discharged. One to two welding stations can use mobile welding smoke purifiers for purification treatment, and there are multiple stations in the workshop, We need to develop a centralized welding fume purification and dust removal system with flexible configuration and variable parameters, tailored to the user's working conditions. Below, we will introduce the composition and principle of the welding fume purification and dust removal system

焊烟净化除尘器系统是由除尘器，风机，管道，吸气臂（吸尘罩），排放烟囱等组成。用于焊接烟气净化的除尘器可采用两种，一种为脉冲滤筒除尘器，一种为脉冲布袋除尘器。

The welding fume purification dust collector system is composed of a dust collector, fan, pipeline, suction arm (dust hood), discharge chimney, etc. There are two types of dust collectors used for welding flue gas purification, one is pulse filter cartridge dust collector and the other is pulse bag dust collector.

脉冲滤筒除尘器采用滤筒来对焊烟进行吸附和过滤，滤筒表面折成褶，布置密度大，可以对细微粉尘有很好的净化效果。采用脉冲清灰，同体积除尘器过滤面积相对较大，过滤风速较小，阻力不大。滤筒的安装方式可做成竖插式和斜插式（沉降式）两种。

The pulse filter cartridge dust collector uses a filter cartridge to adsorb and filter welding smoke. The surface of the filter cartridge is folded and arranged with high density, which can have a good purification effect on fine dust. Using pulse cleaning, the same volume dust collector has a relatively large filtration area, low filtration wind speed, and low resistance. The installation method of the filter cartridge can be made into two types: vertical insertion and oblique insertion (settlement type).

脉冲布袋除尘器采用除尘布袋来对粉尘进行过滤和吸附，除尘布袋的材质很多种，可以满足多种工况的除尘需求，同等过滤面积的，要比滤筒除尘器外形大一些，高度高一些。和滤筒除尘器一样采用高压脉冲清灰，可以有效地对含尘气体过滤吸附和达标排放。

Pulse bag dust collector uses dust removal bags to filter and adsorb dust. There are many types of dust removal bag materials that can meet the dust removal needs of various working conditions. For the same filtering area, it is larger in appearance and higher in height than the filter cartridge dust collector. Like the filter cartridge dust collector, high-pressure pulse dust cleaning can effectively filter, adsorb, and discharge dust containing gases up to standard.

车间焊烟净化的主管道要和除尘器、风机的型号参数匹配，材质可以采用碳钢管和镀锌管两种，在车间上方或者车间墙上布置主管道，然后再分支到每个工位，焊接小工件的用吸气臂就可以，吸气臂可以任意方向活动，非常方便，如果焊接大工件，则需要安装一个吸尘罩，这样可以有效的把焊烟通过吸尘罩，管道，引到除尘器进行过滤净化。

The main pipeline for welding smoke purification in the workshop should match the model parameters of the dust collector and fan. The materials can be carbon steel pipes and galvanized pipes. The main pipeline should be arranged above the workshop or on the workshop wall, and then branched to each workstation. For welding small workpieces, the suction arm can be used, and the suction arm can move in any direction, which is very convenient. If welding large workpieces, a vacuum hood needs to be installed, This can effectively introduce welding smoke through the vacuum hood, pipeline, and dust collector for filtration and purification.

脉冲滤筒除尘器和脉冲布袋除尘器的工作原理一样;含尘气体进入除尘器灰斗后，由于气流端面突然扩大，气流中一部分颗粒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，通过布朗扩散和筛滤等综合效应，使粉尘沉积在滤料表面，净化后的气体进入净气室由排气管经风机排出。

The working principle of pulse filter cartridge dust collector is the same as that of pulse bag dust collector; After the dust containing gas enters the dust hopper of the dust collector, due to the sudden expansion of the airflow end face, a portion of the coarse dust particles in the airflow settle under the action of gravity and inertia force. After the fine and small density dust particles enter the filter chamber, they deposit on the surface of the filter material through comprehensive effects such as Brownian diffusion and screening. The purified gas enters the purification chamber and is discharged by the exhaust pipe through the fan.

除尘器的阻力随滤料表面粉尘层厚度的增加而增大，阻力达到某一限定值时，清灰系统气动，进行清灰，此时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出一股高速、高压的引射气流，从而形成一股相当于引射气流体积1-2倍的诱导气流，一同进入除尘布袋或滤筒内，使之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。

The resistance of the 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 certain limit value, the dust cleaning system is pneumatically operated to clean the dust. At this time, the pulse control instrument controls the opening and closing of the pulse valve. When the pulse valve is opened, the compressed air in the air bag sprays out a high-speed and high-pressure jet airflow through the small hole on the blowing pipe through the pulse valve, forming an induced airflow equivalent to 1-2 times the volume of the jet airflow, Enter the dust removal bag or filter cylinder together, causing an instant positive pressure and causing bulging and micro movement; The dust deposited on the filter material falls off and falls into the ash hopper. The dust inside the hopper is continuously discharged through the ash discharge valve.
