Abstract
The utility model discloses a spray paint waste gas purifying and treating system. The spray paint waste gas purifying and treating system comprises a spray paint waste gas conveying pipe, a vortex plate tower, a defogger, a low-temperature plasma purifier and an induced draft fan, wherein the vortex plate tower, the defogger, the low-temperature plasma purifier and the induced draft fan are communicated in sequence; the vortex plate tower is used for cooling spray paint waste gas and removing particulate matters from paint fog; the defogger is used for filtering water fog and the paint fog; the low-temperature plasma purifier is used for pyrolyzing organic molecules in the spray paint waste gas and converting the organic molecules into innoxious gas molecules; the induced draft fan is used for exhausting the innoxious gas molecules to the atmosphere. The spray paint waste gas purifying and treating system is simple in structure, short in process, safe, reliable, high in purifying efficiency, high in operability, low in investment, and low in operation cost. When the waste gas passes through the plasma generator (i.e. the low-temperature plasma purifier), the organic molecules in the waste gas are subjected to inelastic collision under the action of a high-voltage pulse electric field, chemical bonds of the organic molecules are broken, a series of oxidation chemical reactions and degradation chemical reactions occur to the organic molecules, and finally the poisonous noxious organic matters are converted into innoxious carbon dioxide, water and the like. Thus, the waste gas is purified.
Description
Technical field
The utility model relates to environmental protection purifying equipment technical field, relates in particular to a kind of lacquer spraying waste gas cleaning treatment system that lacquer spraying waste gas is processed that is applied to that is applicable to industrial circle.
Background technology
In spraying industry, be generally to adopt " wet process technique ", first resin is made into glue with organic solvent, then by oil supply system, paint is then carried out to levelling and oven dry by spray gun uniform fold to surface of the work.Because the organic solvent in paint contains a large amount of VOCs (VOC) that formaldehyde, benzene, toluene etc. are main component of take.In levelling and drying course, a large amount of VOC can evaporate.If the VOC evaporating is directly discharged in paint spray booth, it can mix with air, and is diffused into rapidly in the surrounding enviroment at production operation scene.When these VOC surpass finite concentration in air, not only heavy damage environment for human survival but also the health that directly endangers operator.Therefore,, along with the enhancing of people's environmental consciousness, the exhaust-gas treatment problem producing in lacquer spraying technique comes into one's own all the more.
At present, the method that is applied to lacquer spraying waste gas purified treatment mainly contains absorption method, absorption process, Production by Catalytic Combustion Process, flame combustion method etc., yet, this several method all cannot purify the coating cloud particle in lacquer spraying waste gas completely at present, the object of accomplishing to turn harm into good, fully recycling, purification efficiency is low, poor stability, poor stability, operating cost are high.
Utility model content
The purpose of this utility model is to provide a kind of lacquer spraying waste gas cleaning treatment system, and to overcome, the lacquer spraying waste gas purification efficiency of prior art is low, poor stability, poor stability, defect that operating cost is high.
To achieve these goals, the technical solution of the utility model is:
Lacquer spraying waste gas cleaning treatment system, comprise lacquer spraying waste gas carrier pipe and the rotating stream tray scrubber, demister, low-temperature plasma purifier, the air-introduced machine that are communicated with successively, described rotating stream tray scrubber is lowered the temperature to lacquer spraying waste gas and is removed the particle in coating cloud, described demister filters water smoke and coating cloud, organic molecule in described low-temperature plasma purifier cracking lacquer spraying waste gas, change into innocuous gas molecule, after by air-introduced machine, send into atmosphere;
Described rotating stream tray scrubber, comprise housing and spiral board, described spiral board is arranged at enclosure interior, and below is provided with downspout, and a port is located at the junction of spiral board and inner walls, oblique lower deflection housing center, another port, spiral board top is provided with spray system, and the top of described housing is provided with air outlet, is communicated with demister, the sidepiece of housing is provided with air inlet, is communicated with waste gas pipeline;
Described low-temperature plasma purifier, comprise three groups of filter chambers that are communicated with successively, one-level core body chamber, one-level maintenance chamber, secondary core body chamber and secondary maintenance chamber, described filter chamber is provided with screen pack, and one-level core body chamber and secondary core body chamber are provided with a plurality of anode carriers and minus plate.
As the improvement to technique scheme, on described waste gas pipeline, be provided with Middle pressure draught fan.
As the improvement to technique scheme, described rotating stream tray scrubber air inlet place arranges a resistance paint net.
As the improvement to technique scheme, described demister is mesh mist eliminator.
Lacquer spraying waste gas cleaning treatment system of the present utility model has the advantages such as technique is simple, flow process is short, safe and reliable, purification efficiency is high, operability is good.Small investment and running cost are low, and Operation and Maintenance is simple and convenient.When waste gas process plasma generator, under the effect of high-pressure pulse electric, in waste gas, organic molecule carries out inelastic collision, make organic molecule chemical bond rupture, there is a series of oxidations, degraded chemical reaction, finally make toxic organics in waste gas change harmless carbon dioxide and water etc. into, waste gas is purified.
