Technical field
The invention belongs to VOCs exhaust-gas treatments field, and in particular to a kind of 4 S auto shop sprays emission-control equipment
Background technology
Painting dressing automobiles be can produce in automobile making, a significant process of care and maintenance, coating process it is substantial amounts of useless
Gas.4 S auto shop is the main place of vehicle maintenance and maintenance, and 4 S auto shop coating waste gas total amount even more high is in automobile making
Process sprays waste gas total amount.The main component of coating waste gas is coating cloud and organic exhaust gas.The main component of organic exhaust gas be triphen,
Ester, aldehyde, ketone, ether and other compounds.Coating cloud and organic exhaust gas can cause very big harm to the health of people.
Application refers to metal and nonmetallic surface protective mulch or decorative layer, is that product surface protection and decoration are used
Most basic technological means.Coating process can be simply summarized as：Pre-treatment → spraying → drying or solidification.Pre-treatment is general
Including oil removing, derusting, passivation (phosphatization) technique.Required for different coatings and to erosion-resisting, oil removing, derusting, phosphatization etc.
Processing method will be selected depending on the situation of workpiece raw material.In preceding processing derusting process, sandblasting, ball blast or technique for grinding,
Use is selected on demand in the different departments of different industries.With developing rapidly for application techniques, application automated production has significantly
Progressive, electrostatic spraying, electrophoretic coating, powder spray technology have obtained application.
According to manufacturing technique for painting dressing, coating waste gas mostlys come from pre-treatment, spraying, drying process, the pollution discharged
Thing is mainly：The dust or acid mist produced in pretreatment process, the coating cloud and organic solvent produced during spray painting, is produced during drying and volatilizing
Raw organic solvent.Coating cloud mostlys come from the part that solvent based coating disperses in aerial spraying operation, and its composition is with being used
Coating it is consistent.Organic solvent mostlys come from solvent, the diluent during coating use, overwhelming majority category volatility row
Put, its main pollutant is dimethylbenzene, toluene, benzene, butyl acetate, naphtha etc..The harmful exhaust discharged in application is main
Concentrate on painting line, wherein paint spray booth, paint, drying chamber are the main occurring sources of waste gas.
Substantial amounts of paint slag, dust, peculiar smell for being produced when spraying etc., can enter human body by respiratory tract, produce human body
The symptoms such as raw dizziness, nausea, also result in aplastic anemia when serious.Spraying waste gas is not only polluted to environment, and right
Human body has larger damaging effect, while also destroying the environment on periphery, causes bad influence.For environmental protection, state
Emission control of the family to paint industry VOC organic exhaust gas is more and more stricter, and lacquer spraying waste gas needs effectively to be administered and reach ring
It can be discharged after guaranteed request.
