Description

Technical Field

[0001] The utility model relates to the technical field of grinding and gas cutting room equipment, in particular to a dust removal device used for grinding and gas cutting rooms. Background Art

[0002] The process of automobile maintenance involves various maintenance processes, such as grinding and gas cutting of automobile parts. This step will generate a large amount of harmful gas or dust, which will cause a large amount of dust impurities and harmful gases to float in the air. This air state will not only cause harm to the human body, but also easily cause serious problems such as explosion. In order to solve this problem, maintenance plants often use grinding rooms for closed maintenance operations and use air purifiers for air purification, so as to avoid harm to the human body and explosion problems.

[0003] Existing air purifiers in grinding and gas cutting rooms often only have a filtering function. As the use time increases, dust and other impurities accumulate on the filter, causing the efficiency of gas passing through the filter to become lower. At this time, the air purifier needs to be manually dismantled for cleaning or the filter components in the air purifier need to be replaced, which reduces the use time of the filter components. At the same time, traditional air purifiers cannot purify the harmful gases generated during grinding and gas cutting. Utility Model Content
