焊接作为一种对金属进行加热的方式，在建筑、机械制造、汽车生产等行业中应用十分广泛，不过与此同时也会产生大量有害气体，特别是在通风条件欠佳的工厂车间里，焊接烟尘的浓度会大幅上升，会对工人的身体造成极大伤害。焊接烟尘粒子直径细小、粘性较强、温度较高，鼻毛和鼻粘膜无法起到阻挡作用，会直接侵入肺组织，引发尘肺病，要是进入血液还会导致中毒，像氢中毒和锰中毒就很常见。

　　Welding, as a method of heating metal, is widely used in industries such as construction, machinery manufacturing, and automobile production. However, it also generates a large amount of harmful gases, especially in poorly ventilated factory workshops where the concentration of welding fumes can increase significantly, causing great harm to workers' bodies. Welding smoke particles have small diameters, strong viscosity, and high temperatures. Nasal hair and mucous membranes cannot act as barriers and can directly invade lung tissue, causing pneumoconiosis. If they enter the bloodstream, they can also cause poisoning, such as hydrogen poisoning and manganese poisoning, which are very common.

　　一名工人一天能够产生 60-150g 的焊接烟雾，粉尘量相当大。焊烟净化器是一种新型的工业环保废气处理设备，通常应用于电焊、氩弧焊、二保焊以及其他焊接场所，以此达到保护环境和保障工人身体健康的目的。

　　A worker can generate 60-150g of welding smoke per day, with a considerable amount of dust. Welding smoke purifier is a new type of industrial environmental protection waste gas treatment equipment, usually used in welding, argon arc welding, secondary protection welding and other welding sites to protect the environment and ensure the health of workers.

　　焊烟净化器主要分为移动式焊烟净化器和集中式中央焊烟除尘器（以下简称集中式焊烟除尘器）两个大类。那么，这两者之间存在哪些区别呢？

　　Welding smoke purifiers are mainly divided into two categories: mobile welding smoke purifiers and centralized central welding smoke dust collectors (hereinafter referred to as centralized welding smoke dust collectors). So, what are the differences between these two?

　　移动式焊烟净化器，是针对各类工业需求而设计的可移动高效净化器，依据其工作臂的数量、系统方式以及清灰方式等，一般可以分为四大类，即单臂移动式焊烟净化器、双臂移动式焊烟净化器、移动单臂脉冲焊烟净化器、移动双臂脉冲焊烟净化器，适用于局部焊接烟尘的处理，可根据不同的工作地点和工作方式选用不同型号的活动臂管与排气风机。移动式焊烟净化器具有移动灵活平稳、体积小巧、烟尘捕获率高、操作简便、后续维修成本低等特点。

　　Mobile welding smoke purifier is a highly efficient purifier designed for various industrial needs. Based on the number of working arms, system mode, and dust cleaning method, it can generally be divided into four categories: single arm mobile welding smoke purifier, dual arm mobile welding smoke purifier, mobile single arm pulse welding smoke purifier, and mobile dual arm pulse welding smoke purifier. It is suitable for the treatment of local welding smoke and dust, and different models of movable arm pipes and exhaust fans can be selected according to different working locations and working methods. The mobile welding smoke purifier has the characteristics of flexible and stable movement, small size, high smoke and dust capture rate, easy operation, and low subsequent maintenance cost.

　　集中式焊烟除尘器采用除烟主机，借助管路与焊接臂相连接的方式来处理烟尘，适合用于焊接工位较多且相对集中的烟尘净化场景。集中处理不会占用工厂空间，整体布局美观，使用起来也很便利。净化主机运用 PLC 控制，通过脉冲自动反吹清洗集尘，维护起来较为方便。与移动式焊烟净化器相比，集中式焊烟除尘器的适应范围更广。

　　The centralized welding smoke dust collector adopts a smoke removal host, which is connected to the welding arm through pipelines to process smoke and dust. It is suitable for smoke and dust purification scenarios with many and relatively concentrated welding stations. Centralized processing does not occupy factory space, the overall layout is beautiful, and it is also very convenient to use. The purification host is controlled by PLC and automatically cleans and collects dust through pulse back blowing, making maintenance more convenient. Compared with mobile welding smoke purifiers, centralized welding smoke dust collectors have a wider range of adaptability.

　　移动式焊烟净化器适合焊接车间内工位较少且工件体积较小的焊烟收集处理，不适用于工位多、工件大或者机器人焊接手臂的工作环境。而集中式焊烟除尘器能够利用顶吸罩对机器人焊接手臂产生的焊烟进行收集，也可以对焊接机器人工作站进行全封闭或半封闭的收集，此外还能对等离子切割、火焰切割等工艺过程中的烟尘进行净化处理。集中式焊接除尘器更符合环保方面的要求。

　　The mobile welding smoke purifier is suitable for collecting and processing welding smoke in welding workshops with few workstations and small workpiece volumes, and is not suitable for working environments with multiple workstations, large workpieces, or robot welding arms. The centralized welding smoke dust collector can use a top suction hood to collect the welding smoke generated by the robot welding arm, and can also collect the welding robot workstation in a fully enclosed or semi enclosed manner. In addition, it can purify the smoke and dust during processes such as plasma cutting and flame cutting. Centralized welding dust collectors are more in line with environmental requirements.

　　集中式焊烟除尘器的特点：

　　Characteristics of centralized welding smoke dust collector:

　　配备全自动清灰系统，滤材清理更加方便快捷，不需要关停主机和进行其他操作。当滤筒表面的饱和阻力达到特定数值时，自动清洁功能就会启动，并在主机工作过程中依次对各个滤筒单元进行单独反吹清洁，确保集中式焊烟除尘器始终处于良好的工作状态。

　　Equipped with a fully automatic dust cleaning system, filter material cleaning is more convenient and efficient, without the need to shut down the host or perform other operations. When the saturation resistance on the surface of the filter cartridge reaches a specific value, the automatic cleaning function will be activated, and each filter cartridge unit will be individually backwashed and cleaned during the operation of the main engine, ensuring that the centralized welding smoke dust collector is always in good working condition.

　　滤筒采用进口聚酯纤维过滤材料，过滤效率达到 99.5%，在正常使用条件下，滤筒的使用寿命比普通滤料要长得多，还可以选择配置不同滤料的过滤筒，比如覆膜滤筒、阻燃滤筒等，以满足对不同性质烟尘的清除或空气过滤需求。

　　The filter cartridge is made of imported polyester fiber filter material, with a filtration efficiency of 99.5%. Under normal use conditions, the service life of the filter cartridge is much longer than that of ordinary filter media. It is also possible to choose filter cartridges with different filter media, such as membrane filter cartridges, flame retardant filter cartridges, etc., to meet the needs of removing different types of smoke and dust or air filtration.

　　滤筒的更换方式为抽取式，不需要使用任何辅助工具就能进行更换。设备的左、右侧面都设有管路接口，用户可以根据使用场合自由选择。

　　The replacement method of the filter cartridge is extraction type, which can be replaced without the use of any auxiliary tools. The left and right sides of the device are equipped with pipeline interfaces, which users can freely choose according to their usage scenarios.

　　滤筒采用 15° 倾斜抽屉式安装，能让滤筒的拆换更加方便，而且集中式焊烟除尘器本体内不设置传动部件，减少了维修所需的时间。

　　The filter cartridge adopts a 15 ° inclined drawer installation, which makes the removal and replacement of the filter cartridge more convenient. In addition, the centralized welding smoke dust collector does not have transmission components in the body, reducing the time required for maintenance.

　　所配置的高性能离心风机，吸风量较大，吸力强劲。可以通过控制板面上的数字仪表来观察过滤筒的运行状况。集中式焊烟除尘器对颗粒的净化精度能够达到 0.01μm，能够极大地改善整体空间的烟尘污染情况。

　　The high-performance centrifugal fan configured has a large suction volume and strong suction power. The operation status of the filter cartridge can be observed through the digital instrument on the control panel. The centralized welding smoke dust collector can achieve a purification accuracy of 0.01 μ m for particles, which can greatly improve the overall smoke and dust pollution in the space.
