Description

A workshop vacuum system

technical field

The invention belongs to the technical field of environmental protection dust removal air ducts, and particularly relates to a workshop vacuum cleaning system.

Background technique

At present, various metal or non-metal ore mining, material processing, coal mine, and building materials production enterprises will generate a large amount of dust during production. According to the requirements of national environmental protection, various dust collectors are installed on the operation site of many enterprises to collect dust in the operation workshop. However, from the current situation, the dust collectors installed by various dust-producing enterprises mainly collect dust from material transfer stations, cutting points, discharge ports, etc. There is no special treatment equipment for dust on walls, stairs, building corners, etc. The dust in these parts also seriously affects the environmental quality of the site. In the case of personnel walking, equipment operation, air convection, etc., it is easy to cause secondary dust, resulting in increased dust concentration and affecting the physical and mental health of operators. Therefore, the dust treatment on the job site needs to be solved urgently.
