Description

TECHNICAL FIELD

[0002] In the production and manufacturing process of basketball stands, a large amount of welding work is usually required. In the welding process, welding waste gas is easily generated, which is the gas and dust generated in the welding process. Generally, welding waste gas is directly discharged to the outdoor through a negative pressure pipe. Welding waste gas is the vapor generated by metal and non-metal materials under overheating conditions, which is formed by oxidation and condensation. Therefore, the chemical composition of welding waste gas depends on the composition of welding materials and the materials to be welded and the difficulty of evaporation. Long-term inhalation of electric welding dust can cause electric welding pneumoconiosis. For this reason, many countries have developed special safety and health standards for welding work environment.

[0003] At present, when welding waste gas is sucked and treated, a filter is usually used to filter out smoke dust first, and then an activated carbon adsorption tower is used to adsorb and remove harmful gases in the welding waste gas. When the filter is used for a period of time, the internal holes of the filter element close to the inlet end of the filter will be gradually blocked by smoke dust, resulting in poor use effect of the filter, and thus the filter needs to be replaced. However, the internal holes of the filter element close to the outlet end of the filter which is replaced remain unblocked, resulting in low utilization rate of the filter element, and thus increasing the treatment cost of welding waste gas.
