Description

A kind of lacquer spraying waste gas treatment system and technique
Technical field
The invention belongs to metal and manufacture the exhaust-gas treatment of manufacture field, specifically a kind of lacquer spraying waste gas treatment system and technique.
Background technology
In today of rapid economic development, the people's quality of life improves day by day, and the product of many change lives is following, in the new product of metal manufacture processing, " spraying paint " this operation is arranged greatly.The mankind's existence be unable to do without air, and the change of the variation of air physical character and chemical composition all directly has influence on the health of human body.Produce a certain amount of organic exhaust gas in the production process of spraying paint, these organic exhaust gas major pollutants are benzene,toluene,xylene etc.The organic gas that this waste gas is contaminative, slightly, containing toxicity, irritant smell, have larger harm to health and surrounding enviroment.For improving working environment and ensureing the healthy of workman, enterprise need take practicable lacquer spraying waste gas control measures to reduce health and surrounding enviroment harm that pollutant emission reduces venomous injurant confrontation painting workshop workman.
Current conventional lacquer spraying waste gas processing method has: firing method, bioanalysis facture, condensation separation method etc.But all be not suitable for the VOCs treatment of low concentration, large discharge capacity, and floor space is large, investment is large, and cost is high.
Summary of the invention
The object of the present invention is to provide a kind of lacquer spraying waste gas treatment system and technique.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of lacquer spraying waste gas treatment system, it is characterized in that, comprise centrifugal blower, multipole spray system, purifier, circulating water pool, water circulating pump, described centrifugal blower is connected with multipole spray system, described multipole spray system also is connected with purifier, and described water circulating pump one end is arranged in circulating water pool, and circulating water pool supplies water to multipole spray system.
Described multipole spray system includes one-level spray, secondary spray, and described one-level spray is connected with the secondary spray.
Described purifier inside is provided with sorbing material.
Described sorbing material is cellular activated carbon or NACF.
The present invention also provides a kind of lacquer spraying waste gas treatment process, it is characterized in that, comprises the following steps:
(1) water circulating pump pumps into multipole spray system by the water in circulating water pool, and centrifugal blower is blown into multipole spray system by lacquer spraying waste gas, and multipole spray system is removed dust, particle, benzene,toluene,xylene in lacquer spraying waste gas;
(2) the multipole spray system of step (1) waste gas out enters purifier, further adsorbs dust, particle, benzene,toluene,xylene in lacquer spraying waste gas, the waste gas qualified discharge of discharge.
Beneficial effect of the present invention:
1, the present invention adopts absorbing process, with reclaiming class organic waste-gas purification equipment, compares, and need not be equipped with the optional equipments such as compressed air, steam and cooling tower, and running does not produce secondary pollution, and equipment investment is low.
2, the present invention adopts cellular activated carbon or NACF as sorbing material, the adsorbent long service life, and the adsorption system resistance is low, there is efficiency of dust collection high, do not stop up, the advantage that resistance is little, the water smoke clearance is high, efficiency of dust collection >=95%, water smoke clearance >=90%, purification efficiency is higher than 90%.
3, the present invention can be used for purified treatment and produces continuously the organic exhaust gas of generation and also can be used for the organic exhaust gas that batch production process produces.
4, the present invention adopts the water spray process, and water resource is easy to get, low price, but reuse after filtering, precipitating simultaneously reduces the waste of water resource to greatest extent, greatly reduces the lacquer spraying waste gas processing cost.
