Description
Technical field
The utility model relates to a kind of coating cloud clarifier, the coating cloud clarifier in especially a kind of lacquer spraying technique.
Background technology
Lacquer spraying technique is widely used in the surface anticorrosion and decoration of materials such as metal, plastics and timber.Spray paint and generally in paint spray booth, carry out, and blowing and discharging fan is set, to satisfy air purity in the paint spray booth, explosion-proof and operating personnel's working environment requirement.The paint that has added diluent in the lacquer spraying technique forms fine particle by spray gun, accepts the working surface of paint and attach to form paint film by spray power or static directive.In painting process, most of paint forms paint film at surface of the work, and some coating cloud is then along with air-flow is escaped.General paint spray booth is caught these coating clouds by cascade is set, but has the part coating cloud to efflux with air draft, forms coating cloud and pollutes.Moreover most of diluent becomes gas mutually in spraying process, and by the discharging of paint spray booth exhaust blower, forms organic solvent contamination.Therefore, in the exhaust emission of paint spray booth, mainly be that coating cloud pollutes and organic solvent pollutes.According to the national environmental protection rule and standard, these two kinds of pollutions all need to administer.
In the improvement method that coating cloud pollutes, mainly contain wet method and dry method dual mode.
(1) dry treatment:
The dry treatment coating cloud pollutes the main mode that adopts filter cotton to filter, and promptly adopts the efficient paint mist filter cotton to filter the air-flow that contains coating cloud, and the coating cloud particulate filter is got off.This filter cotton has the filter densities of variation, and the filter cotton of windward side is the most fluffy, and the aperture is bigger, progressively reduces then, and main purpose is the dustiness that strengthens filter cotton, makes filter cotton be unlikely to very fast obstruction.The filter efficiency of this coating cloud filter cotton is higher, but also has some shortcomings.At first, along with filter cotton contains the increase of lacquer amount, exhaust resistance increases sharply, and therefore must select high-head air draft blower fan, to guarantee the pressure balance of paint spray booth.The required electrical power of this air draft is multiplied, and operating cost improves greatly, and, because windage progressively rises, for the higher paint spray booth of ask for something, exhaust blower must be equipped with frequency converter could guarantee the paint spray booth constant pressure, increases the investment cost of system; Secondly, the filter cotton use of can't regenerating after inhaling full coating cloud can only be changed.In the with serious pollution occasion of coating cloud, frequently change the coating cloud filter cotton.There are strict requirements because filter method is to filtering windward side speed, and under the big air quantity situation, coating cloud filter cotton use amount is very big, and operating cost is surprising; At last, the filter cotton of inhaling the coating cloud of having satisfied can only landfill or burning disposal, forms secondary pollution, increases the expense of post processing.Moreover the ability of filter cotton absorption gas phase organic solvent is limited, and the gas phase organic solvent that is not adsorbed still spreads in air, continues contaminated environment.
(2) wet method is administered:
It mainly is to catch coating cloud by cascade cabinet, washing cabinet that wet method is administered.Its basic principle has two aspects.On the one hand be paint particles when running into the moisture film that cascade cabinet and washing cabinet form on baffle plate, can caught and take in the pond by moisture film.Be after paint particles and water water droplet unrestrained or atomizing contacts, to be gone in the pond on the other hand by the water droplet capture zone.Paint in water is by the effect of flocculating agent, and by precipitation or floatingly separates with water body, and formation is coated with lacquer slag and salvaged processing.Adopt the cascade cabinet to handle mode extensive use in the industry of spraying paint of coating cloud.But this mode exists some shortcomings, can catch most coating cloud particle though design good cascade cabinet, absolutely contacts with moisture film or water droplet owing to can not guarantee the coating cloud particle, still has part coating cloud particle to break away from cascade and escapes.Also have behind cascade the washing of increasing cabinet strengthen the way that coating cloud is caught, but the side effect of this way is to be equal to or greater than under the situation of air themperature in water temperature, the process of washing is actual to be process to air wetting.In the improvement of lacquer spraying waste gas, the method for charcoal absorption is generally adopted in the improvement of organic solvent, and air humidity is very big to the adsorption effect influence of active carbon, too high relative humidity makes the adsorption effect of active carbon descend greatly even is entirely ineffective.Therefore, the method that adopts washing to handle coating cloud has solved the coating cloud pollution problem, but has brought difficulty for simultaneously the improvement of organic solvent, moreover, it is big that water-washing method is handled the coating cloud floor space, and need solve the problem that paint in the recirculated water stops up water pump or nozzle when adopting recirculated water.In addition, when the row of wind of paint spray booth hour, the coating cloud particle that is suspended in the top can sink, if drop on surface of the work, then workpiece surface quality is worked the mischief.In addition, when dull and stereotyped ground is adopted on the ground of paint spray booth, on the suspension coating cloud particle sinking flat board, cleaning has been increased workload.
Summary of the invention
The purpose of this utility model is the existing in prior technology defective of polluting at above-mentioned improvement coating cloud, a kind of combustibility of utilizing coating cloud itself is proposed, by collecting coating cloud, burning, the method that combustion product gases is purified again, coating cloud is carried out the dry type coating cloud clarifier of innoxious purified treatment, to improve the clean-up effect of coating cloud.
