Description

Technical Field

[0001] This utility model relates to the field of fume hood technology, and more specifically, to a dust collection fume hood. Background Technology

[0002] Dust collection hoods, also known as smoke hoods or suction hoods, are an important component in flue gas collection and treatment. They are the front-end components for flue gas collection. The dust collection hood uses the suction force generated by a fan to draw oil fumes and particulate matter from the air into a filter. The filter typically uses a metal mesh or activated carbon filter plate, which effectively removes oil fumes and particulate matter from the air. The purified air is then discharged through the exhaust vent, reducing indoor air pollution. Because the dimensions of dust collection hoods vary depending on usage requirements, it is necessary to adjust their size.

[0003] In related technologies, during the use of dust collection hoods, the size of the dust collection hood is usually selected and replaced by the staff according to the actual usage needs and the power of the external filter.
