Welding fume purification system and use method thereof

Abstract

The invention provides a welding fume purification system, and belongs to the technical field of welding fume purification equipment, the welding fume purification system comprises a primary dust removal filter and a secondary dust removal filter communicated with the primary dust removal filter, and an air outlet of the secondary dust removal filter is communicated with a purification box through a pipeline; each of the first-stage dust removal filter and the second-stage dust removal filter comprises a filter cartridge dust removal box, a detachable filter cartridge fixed through a filter cartridge fixing frame is arranged in the filter cartridge dust removal box, and a fan is arranged in an upper box body above the filter cartridge dust removal box; a speed regulation air inlet box is arranged at an air inlet of the second-stage dust removal filter; a speed reduction baffling assembly positioned above the filter cartridge is arranged in the second-stage dust removal filter; the purification box is internally provided with a uniform flow air outlet assembly communicated with the air inlet, and an activated carbon adsorption layer opposite to the uniform flow air outlet assembly; the first-stage dust removal filter and the second-stage dust removal filter effectively filter particles and dust in welding fume, harmful gas in the welding fume is effectively purified and treated through the purification box, and efficient treatment of the welding fume is achieved.

Description

technical field [0001] The invention relates to the technical field of welding fume purification equipment, in particular to a welding fume purification system and a method for using the same. Background technique [0002] Welding fume purification system is a kind of industrial environmental protection equipment, which is usually used in welding places such as tin welding and hand arc welding to collect welding fume generated by purification, so as to protect the environment and the health of workers. It is a purification device specially designed for the treatment of small metal particles suspended in the air that are harmful to the human body during welding, cutting and grinding. 95% of the large amount of smoke generated in the welding process comes from the particles generated by the solder, and 5% is the harmful gas generated by the volatilization of the flux in the solder. This smoke particle will be adsorbed in the human lungs. In such an environment, there will be ...

Problems solved by technology

[0003] The current welding fume purification system adopts a high-altitude discharge after dust removal and filtration to deal with harmful gases. There is still a small amount of dust in the discharged gas, and the treatment of particle dust needs to be optimized; in addition, in the structure of using activated carbon to deal with harmful gases, it is impossible It is convenient to replace activated carbon. Saturated activated carbon cannot effectively purify. The usual activated carbon replacement is troublesome and not timely, which reduces the convenience and safety of the existing welding fume purifier.
