Background technique

With the rapid economic improvement and the rapid development of the manufacturing industry, processing plants of various types have been rapidly established. During the manufacturing process, the plants will produce a large amount of suspended smoke, particulate dust and odorous gases, especially in This is particularly obvious in workshops with a large number of welding tasks. These fumes not only affect the health of workers, but also when the generated fumes are directly dispersed into the atmosphere, they will also disrupt the natural ecological balance and cause environmental pollution. Among them, welding fumes are purified. As the equipment used in the factory to filter exhaust gas such as smoke and odor generated during the welding process, in recent years, welding fume purification equipment has become more and more popular in the processing industry.

Although the existing welding fume purification equipment has the above advantages, the welding exhaust gas filtered by the welding fume purification equipment often contains dust. If it is discharged to the atmosphere, it will still cause environmental pollution to a certain extent, which is poor in practicality and easy. Technical problems that cause secondary dust in the surrounding environment.
