Description
Technical field
The utility model is related to a kind of volatile organic matter（VOCs）Prevention and cure of pollution device, more particularly to a kind of spraying is useless
Gas purifying processing device.
Background technology
The main waste gas that produces in the production process including coating and during use of spraying waste gas, is modern industry
Inevitable pollutant, its sensory experience to people, it is even healthy cause harm, need badly and administered.Particularly
The use of coating is in extensive range, can be applied to vehicle spray painting, furniture spray paint, equipment spraying, electronic product spraying, packing material surface
The fields such as spraying.In actual production, many medium-sized and small enterprises use outdoor spraying；The strict place of some environmental requirements, production
Enterprise uses the plan of the rights and interests such as cascade filtering, charcoal absorption；Simultaneously as spraying waste gas is low concentration, big flow, normal temperature give up
Gas, control《Atmosphere pollution comprehensive discharge standard》, some enterprises take the method for high altitude discharge, although this method can be met
Current discharge standard, but waste gas is substantially unprocessed dilution discharge, and the harm caused to air is also very serious.
Volatile contaminant in lacquer spraying waste gas is water insoluble, is just to remove coating cloud and formed with the purpose of water curtain or cascade
Slag is painted, and painting slag needs to be used as solid waste progress special disposal after periodic cleaning, it is also desirable to carry out sewage disposal.
It is a kind of effective industrial treatment means, organic waste using the microporous characterization of adsorption absorption spraying waste gas of activated carbon
Gas is contacted by adsorbent bed with activated carbon, and the organic pollution in waste gas is attracted to activated carbon surface, so as to be taken off from air-flow
Separate out and, reach clean-up effect.But in view of the economy and environment friendly of processing procedure, i.e., by the work of saturation adsorbing contaminant
Property charcoal must be parsed and be regenerated, make its recover adsorption capacity.Therefore it is once to abandon or make profits again afterwards that activated carbon, which is used,
With being a factor that can not ignore, but the enterprise of many use charcoal absorptions does not use active carbon regenerating technology and dress
Standby, its using effect is well imagined.
In order to ensure the people's livelihood conscientiously, instruct enterprise to select appropriate pollution prevention technique to carry out exhaust-gas treatment, National Environmental
Protection portion is issued《Volatile organic compounds prevention and cure of pollution policy》（Bulletin No. 31 2013-05-24 in 2013 is implemented）, in the policy
And clearly proposed in policy development explanation：
1）Encourage to post-process using closed integrated production technology and to the waste gas categorised collection produced in production process.
2）For the waste gas of the VOCs containing low concentration, adsorption technology, absorption techniques can be used to organic molten by having during recovery value
Qualified discharge after agent is reclaimed；When should not reclaim, Adsorption Concentration combustion technology, biotechnology, absorption techniques, plasma can be used
Qualified discharge after the purification such as technology or ultraviolet light high-level oxidation technology.
In actual production, three benzene concentrations in spraying waste gas are generally below 300mg/m3, wherein paint spray booth exhaust gas concentration
It is lower, generally in 100mg/m3Left and right；For low concentration, the VOCs treatment of Wind Volume, using Production by Catalytic Combustion Process（It is applied to
Concentration is more than 500mg/m3）Processing is improper, and " current photocatalysis oxidation technique has that reaction rate is slow, photon efficiency is low,
Catalyst inactivation, the shortcomings of be difficult to fix, the also non-large-scale application in industrial vocs purification "（In explanation of compilation 2.2.7
Hold）.After technical characterstic comprehensive analysis, it is believed that using plasma technology come handle spraying waste gas be preferable scheme.
In Chinese Ministry of Environmental Protection《Volatile organic compounds prevention and cure of pollution policy（Exposure draft）Explanation of compilation》In, list using etc. from
The structure configuration of body technique, saves content referring to 2.2.6 and 5.6.2, mainly has with Types Below：
1）Cascade demisting+water absorption tower absorption+plasma purification；
2）Process schematic representation is as follows：Waste gas-rotational flow and spray tower-demister-plasma purifier-blower fan-aiutage-reaches
Mark discharge cooling water.
