Abstract

The invention relates to a small-sized tower-shaped combined type waste gas treatment device. The small-sized tower-shaped combined type waste gas treatment device is a treatment device for construction paint of the painting industry, coating cohesive particles and organic waste gas and is mainly suitable for, but not limited to, waste gas treatment of an automobile finish baking house. The small-sized tower-shaped combined type waste gas treatment device comprises a water curtain type gravity dust collection device, a UV high-energy high-ozone lamplight decomposing device and a honeycomb-shaped square activated carbon adsorption device. The working principle is that a draught fan supplies waste gas generated in the coating process in the automobile finish baking house to a tower-shaped treatment device, gravitational dust collection is conducted through a water curtain, and UV high-energy lamplight decomposition is conducted. In order to increase the treatment speed, the draught fan can be used for feeding the waste gas into honeycomb type activated carbon in the tower-shaped treatment device through secondary pressurization for final adsorption and decomposition, and the waste gas is discharged out from an exhaust port after meeting an emission standard.

Description

A kind of small-sized turriform combined type waste gas treatment equipment
Technical field
What the present invention relates to is a kind of small-sized turriform combined type exhaust treatment system, is a kind of paint industry construction paint, coating viscosities particle administers and VOCs treatment device, be mainly applicable to but be not limited to the exhaust-gas treatment that produces in auto repair combined padding and drying system.
Background technology
The pollutant effulent of auto repair is administered along with the expansion of the auto repair produced pollution becomes important, especially the exhaust emission that produces of spray paint.Containing a large amount of carcinogenic substances such as coating cloud, dimethylbenzene in the waste gas that spray paint produces.Process for the volatile organic chemical combination solvent of spray paint generation generally can adopt several way of absorption method, combustion method, decomposition method to solve.The existing equipment that can carry out effectively process to finish-baking room for automobile waste gas, volume is large, cost is high, and maintenance cost, use cost are high, and general maintenance industry is difficult to bear.Most of combined padding and drying system only have employed simple absorption method to the processing mode of volatile organic solvent, the discharge standard of environmental protection far can not be reached to the exhaust-gas treatment produced in vehicle spray painting process, reason is to carry sticky particle secretly in the waste gas such as the benzene,toluene,xylene that paint volatilization produces, the cleaning ambient required for various emission-control equipment can not be met, active carbon in active carbon absorption plant, often become block by oiliness particle adhesion, form the row of stealing and in line present situation that cannot economically use continuously.The present invention mainly solves the miniaturization of waste gas treatment equipment and the problem of low cost, provides a kind of technical scheme of effective waste gas treatment equipment.In prior art, typical technical scheme such as " CN 102784550 A circulation fluid curtain spraying organic waste gas treatment system " institute states, but the greatest drawback of this technical scheme be floor space comparatively greatly, low cost, miniaturization can not be realized.The invention provides a kind of design of small-sized turriform combined type waste gas treatment equipment, mainly solve the miniaturization of waste gas treatment equipment and the problem of low cost, provide a kind of technical scheme of effective waste gas treatment equipment.
Summary of the invention
The present invention is directed to the deficiency of existing vehicle spray painting waste gas treatment equipment, a kind of small-sized turriform combined type waste gas treatment equipment is provided.
The design of this waste gas treatment equipment, have employed turriform layered combination structure, brings three processing links into a rack, realizes Miniaturization Design.Cost is low, easy to maintenance, at the bottom of use cost.
The present invention solves the generation organic exhaust gas that sprays paint to affect because carrying sticky particle secretly the present situation that waste gas treatment equipment could normally use and cause secondary pollution, for the equipment providing a set of low cost movement up to standard to avoid producing secondary pollution is administered in blowdown.
Small-sized turriform combined type waste gas treatment equipment realizes by the following technical solutions: the waste gas produced in combined padding and drying system spraying process is sent into tower treatment facility by blower fan, carry out gravitational dust collection by cascade, UV high energy light decomposes, for improving processing speed, last adsorption-decomposition function can be carried out by the choice for use blower fan secondary pressurized honeycomb fashion active carbon of sending into tower treatment facility, discharge from exhaust outlet after reaching discharge standard.
Small-sized turriform combined type waste gas treatment equipment is reasonable in design, exhaust-gas treatment is divided into three links.First by dust arrester by pollutant maximum for quantity in waste gas---coating cloud processes.Water is administered, for organic waste gas treatment equipment provides the organic exhaust gas not with sticky particle thing the part paint sticky particle thing not adhering to coated article in construction of spraying paint by circulation fluid curtain; Secondly, organic exhaust gas not with sticky particle thing enters waste gas decomposing processor, the method that main employing light decomposes, makes organic exhaust gas micel under low-temperature plasma splitting action, by the open loop of triphen scission of link, be decomposed into subset, namely become carbon dioxide and water by ozone oxidation, the small organic molecule group be not completely broken down, enters photodissociation cleansing phase, by length ultraviolet line scission of link, form carbon dioxide and the purification of water twin-stage; Finally by adsorbent equipment, mainly adopt charcoal absorption, further effective adsorption treatment is carried out to the waste gas after decomposition, ensure that the purification up to standard of spraying organic exhaust gas, reach discharging standards.
