布局灵活，适用于各种多工位焊接生产线的除尘使用。多工位集中式除尘系统主要由净化器主机、通风管、吸气臂、集气罩等部分组成。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。

Flexible layout, suitable for dust removal in various multi station welding production lines. The multi station centralized dust removal system mainly consists of a purifier host, ventilation pipes, suction arms, gas collection hood, and other parts. 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 pipe and galvanized pipe. The main pipeline should be arranged above the workshop or on the workshop wall, and then branch 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 filter and purify welding smoke by passing it through the vacuum hood, pipes, and leading it to the dust collector.

焊接车间烟尘处理设备，采用?PTFE滤料制成的特制滤筒（聚酯?+覆膜），?同时具有膜过滤和刚性机体过?滤的特点。?坚固的刚性过滤体能承受较高的工作压力，?不需任何骨架支撑，?并能受一?定的机械冲击力，?反吹时滤筒不变形。?由于除尘器面板采用螺栓紧固易于拆装，?滤筒?采用三耳吊装，因此安装和更换滤筒极为方便。

Welding workshop smoke and dust treatment equipment, using? Specially made filter cartridge made of PTFE filter material (polyester?+membrane coating),? Simultaneously having membrane filtration and rigid body filtration? The characteristics of filtration.? A sturdy and rigid filter body can withstand high working pressure,? No skeleton support required,? And can it withstand one? Fixed mechanical impact force,? The filter cartridge does not deform during reverse blowing.? Due to the use of bolt fastening on the dust collector panel, it is easy to disassemble,? Filter cartridge? Using three ear lifting, it is extremely convenient to install and replace the filter cartridge.

滤筒式除尘器的结构是由进风管、排风管、箱体、灰斗、清灰装置、导流装置、气流分流分布板、滤筒及电控装置组成，类似气箱脉冲袋式除尘器的结构。

The structure of a filter cartridge dust collector is composed of an inlet duct, an exhaust duct, a box body, an ash hopper, an ash cleaning device, a guide device, an airflow distribution plate, a filter cartridge, and an electrical control device, similar to the structure of an air box pulse bag dust collector.

滤筒在除尘器中的布置很重要，既可以垂直布置在箱体花板上，也可以倾斜布置在花板上，从清灰效果看，垂直布置较为合理。花板下部为过滤室，上部为气箱脉冲室。在除尘器入口处装有气流分布板。

The arrangement of the filter cartridge in the dust collector is very important. It can be vertically arranged on the box flower board or obliquely arranged on the flower board. From the perspective of the cleaning effect, the vertical arrangement is more reasonable. The lower part of the flower board is a filtering chamber, and the upper part is an air box pulse chamber. An airflow distribution plate is installed at the inlet of the dust collector.

含尘气体进入除尘器灰斗后，由于气流断面突然扩大及气流分布板作用，气流中一部分粗大颗粒在动和惯性力作用下沉降在灰斗；粒度细、密度小的尘粒进入滤尘室后，通过布袋扩散和筛滤等组合效应，使粉尘沉积在滤袋表面上，净化后的气体进入净气室由排气管经风机排出。

After the dusty gas enters the ash hopper of the dust collector, due to the sudden expansion of the airflow cross-section and the action of the airflow distribution plate, some coarse particles in the airflow settle in the ash hopper under the action of dynamic and inertial forces; After the fine particle size and low density dust particles enter the dust filter room, they are combined with bag diffusion and screening to deposit the dust on the surface of the filter bag. The purified gas enters the clean air chamber and is discharged by the exhaust pipe and fan.

滤筒式除尘器的阻力随滤袋表面粉尘层厚度的增加而增大。阻力达到某一规定值时进行清灰。此时PLC程序控制电磁脉冲阀的启闭，首先一分室提升阀关闭，将过滤气流截断，然后电磁脉冲阀开启，压缩空气以及短的时间在上箱体内迅速膨胀，涌入滤筒，使滤筒膨胀变形产生振动，并在逆向气流冲刷的作用下，附着在滤袋外表面上的粉尘被剥离落入灰斗中。清灰完毕后，电磁脉冲阀关闭，提升阀打开，该室又恢复过滤状态。清灰各室依次进行，从一室清灰开始至下一次清灰开始为一个清灰周期。脱落的粉尘掉入灰斗内通过缷灰阀排出。

The resistance of the filter cartridge dust collector increases with the increase of the thickness of the dust layer on the surface of the filter bag. Clean the dust when the resistance reaches a certain specified value. At this time, the PLC program controls the opening and closing of the electromagnetic pulse valve. Firstly, the lifting valve of the first chamber is closed to cut off the filtered airflow. Then, the electromagnetic pulse valve is opened, and compressed air and a short period of time rapidly expand inside the upper chamber, flowing into the filter cartridge, causing the filter cartridge to expand and deform, resulting in vibration. Under the action of reverse airflow erosion, the dust attached to the outer surface of the filter bag is peeled off and falls into the ash hopper. After the ash cleaning is completed, the electromagnetic pulse valve is closed, the lifting valve is opened, and the room returns to the filtering state. Cleaning is carried out sequentially in each room, with one cleaning cycle starting from one room and continuing until the next cleaning. The detached dust falls into the ash hopper and is discharged through the ash discharge valve.

滤筒过滤器具有以下特点：

The filter cartridge filter has the following characteristics:

①粉尘捕集效率高：过滤元件的除尘效率是由其本身特有的结构和涂层来实现?的，适用于极细和特殊粉尘，?通常对?0.3?μm以上超细粉尘的除尘效率可达到＞?99.8?%。?由于焊接、切割烟尘颗粒直径大部分在?0.2?μm以上，因此特别适合金属焊接、切割烟尘的净化过滤。

① High dust capture efficiency: Is the dust removal efficiency of filter elements achieved by their unique structure and coating? Suitable for extremely fine and special dust,? Usually right? 0.3? μ Can the dust removal efficiency of ultra-fine dust above m reach>? 99.8%.? Due to welding and cutting, the diameter of smoke particles is mostly within the range of? 0.2? μ Above m, therefore it is particularly suitable for purifying and filtering metal welding and cutting smoke and dust.

②压力损失稳定：?由于滤筒是通过表面的?PTFE涂层对粉尘进行捕捉的，?其光滑?的表面使粉尘很难透过与停留，?过滤筒母体层中不会发生堵塞现象，?阻力损失仅与过?滤风速有关。

② Stable pressure loss:? Because the filter cartridge passes through the surface? Does PTFE coating capture dust,? Is it smooth? The surface makes it difficult for dust to penetrate and stay,? Will there be no blockage in the mother layer of the filter cartridge,? The resistance loss is only related to? The filtering speed is related.

③采用?PTFE滤料制成的特制滤筒（聚酯?+覆膜），具有阻燃的作用。?④清灰效果好：滤筒的刚性结构，使得脉冲反吹气流向空隙喷出时，滤筒无变?形，表层粘附的粉尘，在瞬间即可被除去。

③ Adopting? A specially made filter cartridge made of PTFE filter material (polyester?+membrane coating) has a flame retardant effect Good dust removal effect: The rigid structure of the filter cartridge ensures that the filter cartridge remains unchanged when the pulse back blowing air flows towards the gap for spraying? The dust adhering to the surface can be instantly removed.

⑤使用寿命可达?1～2年，大大减少了更换滤芯的次数；?滤筒的无故障运行时间?长，不需要经常的维护与保养。

⑤ Can the service life reach? Within 1-2 years, the frequency of replacing filter cartridges has been greatly reduced;? What is the fault free operating time of the filter cartridge? Long, does not require frequent maintenance and upkeep.
