Description
Technical field
The invention belongs to the flocculating agents of painting applications, agglomerate more particularly to one of spray room aerosol type coating cloud is applied to
Agent.
Background technique
Equipment is chronically exposed to air and is perhaps easy to appear corrosion or other chemical reactions in external environment, causes to set
Standby damage influences service life and its function, so needing the spray paint on the surface of equipment or wall surface, is painting
Cheng Zhong generates a large amount of coating cloud and organic solvent gas, influences the health of operator, the environment and sky around serious pollution
Gas.
Spraying exhaust gas not only contains volatile organic matter, also comprising the aerial coating cloud that suspends in spraying process, coating cloud
It will affect subsequent VOCs treatment, so needing to remove coating cloud therein before lacquer spraying waste gas purification, so that next step is to wherein
Volatile organic matter purification treatment.Mainly there are wet purification method and dry cleaning method at present, wherein wet purification method is according to phase
The molten principle of patibhaga-nimitta, by the coating cloud in solvent absorption (or chemical absorbing) lacquer spraying waste gas, common wet purification method has cascade
Formula handles the method for purification without pump water curtain style, venturi type, water rotation type etc..These wet treatment methods are the disadvantage is that coating cloud is attached on room
Wall, pipeline in sink, are rolled into a ball blocking pipeline compared with lacquer using easily being formed for a long time, painted so also needing to be handled using chemical floc
Mist waste water；Dry cleaning method is that lacquer spraying waste gas is entered filter, using the coating cloud and particulate matter in filtering layer detention lacquer spraying waste gas,
Common glass fibre cotton, clinker etc. are used as filtrate, and theoretically filtration method can remove most of coating cloud, and to volatility therein
Organic matter is adsorbed on a small quantity, and this method is without secondary pollution, does not generate waste water；The disadvantage is that filtering is not thorough enough, to equipment pollution
Seriously, easily blocking.
Therefore, it is necessary to develop a kind of aerosol type lacquer mist coagulant of good performance.
Summary of the invention
It is an object of the present invention to overcome the deficiencies of the prior art and provide a kind of aerosol type lacquer mist coagulant, the spray
