焊接烟尘净化器该如何选择？
焊接烟尘对人体的危害
The hazards of welding fumes to human health
焊烟对人体的危害是多方面的，首当其冲的是对肺功能的影响。焊工在焊接作业时，焊条中的焊芯、药皮和金属母材在电弧高温下熔化、蒸发、氧化，产生大量金属氧化物及其它物质的烟尘，长期吸入可引起焊工尘肺。
The harm of welding smoke to the human body is multifaceted, with the first and foremost being its impact on lung function. During welding operations, the welding core, coating, and metal base material in the welding rod melt, evaporate, and oxidize at high arc temperatures, producing a large amount of metal oxides and other substances in the form of smoke and dust. Long term inhalation can cause pneumoconiosis in welders.
其次，焊烟对于神经系统也有损伤。研究表明，焊接烟尘中的锰、铝、铅等元素，可能导致涉及人脑记忆、分析等信息加工处理的功能损害；
Secondly, welding fumes can also cause damage to the nervous system. Research has shown that elements such as manganese, aluminum, and lead in welding fumes may cause functional damage to information processing involving human brain memory and analysis;
再者，焊烟中存在的一些金属氧化物
Furthermore, some metal oxides present in welding fumes
如果被工人吸入，则会导致一些全身性疾病的发生，如乏力、胸闷、气急、肌肉关节酸痛等等。
If inhaled by workers, it can lead to the occurrence of some systemic diseases, such as fatigue, chest tightness, shortness of breath, muscle and joint pain, etc.
焊接烟尘对环境的危害
The hazards of welding fumes to the environment
焊接烟尘如果不经处理就排放，会给大气中留下大量微粒粉尘，它们能在环境中形成雾霾，降低空气能见度，也直接影响植物的光合作用。而烟尘颗粒如果回落到水系中，则会污染水体生态！
If welding fumes are emitted without treatment, they will leave a large amount of particulate dust in the atmosphere, which can form haze in the environment, reduce air visibility, and directly affect plant photosynthesis. If smoke particles fall back into the water system, they will pollute the aquatic ecology!
在环保督查日益严格的今天，焊烟污染无处理排放等于是已经明令禁止了，工厂想要维持正常开工，非配备上焊烟净化设备不可！
In today's increasingly strict environmental inspections, untreated emissions of welding smoke pollution have been explicitly prohibited. If factories want to maintain normal operations, they must equip themselves with welding smoke purification equipment!
从焊烟的捕捉方式角度来讲，我们建议采用源头捕捉的方式来处理焊接烟尘，因为这样最经济、最可靠，而且效果会最好，然而在现实中，一些大型工件、大型钢构厂房、多工位不定点焊接等工况中，实现源头捕捉也不太现实，有的会大大降低工人的工作效率、有的会对其工作路线产生干涉等等。因此，焊接烟尘在净化器布置中需要综合考虑整个现场的工艺路线、焊点布局、工位特点以及工作效率，沟通最适合企业当前工况的处理方式。
From the perspective of capturing welding fumes, we recommend using source capture to deal with welding fumes, as it is the most economical, reliable, and effective method. However, in reality, it is not very practical to achieve source capture in some large workpieces, large steel structure factories, and multi station non fixed welding situations. Some may greatly reduce workers' work efficiency, while others may interfere with their work routes, and so on. Therefore, in the layout of the purifier, it is necessary to comprehensively consider the process route, welding point layout, workstation characteristics, and work efficiency of the entire site, and communicate the most suitable treatment method for the current working conditions of the enterprise.
1、目前常用的捕捉方式有哪几种？
1. What are the commonly used capture methods currently?
（1）焊接烟尘净化单机，配备单万向吸气臂、双万向吸气臂。
(1) Welding smoke purification single machine, equipped with single universal suction arm and double universal suction arm.
（2）多工位万向吸气臂，配中大功率焊接烟尘净化主机。
(2) Multi station universal suction arm, equipped with a medium to high-power welding smoke purification host.
（3）环保焊枪，一般为手工焊接、机器人焊接用。
(3) Environmentally friendly welding guns are generally used for manual welding and robot welding.
（4）局部捕集罩，从正面、侧面设置烟尘罩捕捉。
(4) Local capture hood, set up smoke hood from the front and side to capture.
（5）顶部抽烟罩，在四周配备防护软帘。
(5) Top smoking hood, equipped with protective soft curtains around.
（6）焊接工作站，建立全密封式焊接房。
(6) Welding workstation, establish a fully sealed welding room.
（7）一体式自循环净化单机，类似于柜式空调。
(7) Integrated self circulating purification unit, similar to cabinet air conditioning.
（8）吹吸式整体车间净化系统。
(8) Blow suction integrated workshop purification system.
2、那焊接烟尘净化器主机该如何选型？
2. How to choose the host of the welding smoke purifier?
（1）过滤材质：如果是一般性碳钢、不锈钢的金属焊接，采用阻燃材料过滤材料。如果是铝镁等易燃易爆合金焊接，采用防静电阻燃过滤材料。
(1) Filter material: If it is a metal welding of general carbon steel or stainless steel, flame-retardant filter material should be used. If welding flammable and explosive alloys such as aluminum and magnesium, anti-static and flame-retardant filter materials should be used.
（2）过滤风速：越低越好，综合经济性和实用性。过滤风速≤1.2 m/min。
(2) Filter wind speed: The lower the better, considering both economy and practicality. Filter air speed ≤ 1.2 m/min.
（3）过滤精度：对于当量直径在0.3?m以上的烟尘颗粒过滤精度99%以上。
(3) Filtering accuracy: For an equivalent diameter of 0.3? The filtration accuracy of smoke particles above m is over 99%.
（4）清灰方式：建议使用自动脉冲反吹清灰，避免大量的人工清灰作业，耽误工作效率。
(4) Cleaning method: It is recommended to use automatic pulse back blowing cleaning to avoid a large amount of manual cleaning operations, which may affect work efficiency.
（5）其他选配：前置火花捕集器、隔爆阀、火花探测及熄灭系统、泄爆口、无焰泄爆装置等。
(5) Other optional features: front spark arrester, explosion-proof valve, spark detection and extinguishing system, explosion-proof port, flameless explosion-proof device, etc.
