Technical Field

[0001] This utility model belongs to the field of formaldehyde filtration technology, and specifically relates to a formaldehyde filtration device for glue workshops. Background Technology

[0002] Formaldehyde is a highly toxic substance, ranking second on my country's list of priority controlled toxic chemicals. The World Health Organization has identified formaldehyde as a carcinogen and teratogen, a recognized allergen, and a potential strong mutagen. Currently, some adhesives contain formaldehyde; therefore, some filtration equipment is installed in adhesive production workshops to filter out formaldehyde.

[0003] However, existing formaldehyde filtration devices require employees to clean the filter screen regularly, which is a waste of manpower. At the same time, since activated carbon boards need to be replaced after a period of use, daily maintenance is quite cumbersome. Therefore, a formaldehyde filtration device for glue workshops is proposed. Utility Model Content
