Description
Technical field
The utility model is related to technical field of environment protection equipment, more particularly to a kind of dry type paint spray table of band VOC processing functions.
Background technology
Currently, the paint or coating used in lacquer spraying technique is mostly using organic solvent as main component, in painting process
In, small paint droplet becomes dust particle after organic solvent volatilization.In order to avoid these dust particles are diffused into workshop
In, and then health is influenced, generally use Paint spraying platform as the ancillary equipment of recycling coating cloud in industry.
According to the difference of working media, Paint spraying platform can be divided into wet type Paint spraying platform and dry type paint spray table two major classes.Wherein, wet type
Paint spraying platform is acted on by cascade or water curtain, coating cloud is trapped in catch basin, purified air is directly discharged in air；
Waste water need to pass through double purification processing and could discharge or recycle in catch basin, and the coating cloud collected can be gathered into paint mud,
It needs to handle again.And dry type paint spray table is to trap coating cloud by the form of filter cotton, filter paper or filter cotton+filter paper
, filter cotton and filter paper are just needed replacing at regular intervals.
Dry type paint spray table has the following advantages relative to wet type Paint spraying platform：
