Description
Technical field
The present invention relates to a kind of painting workshop spray tower for waste gas.
Background technique
With the development of economy and society, being required in fields such as electronic manufacture, automobile, chemical industry, building materials in workpiece, equipment
Upper spray painting.Lacquer spraying technique is to be dispersed into uniform and fine droplet by means of air pressure by spray gun, and painting imposes on coated article
Surface.
Contain the organic solvents (the readily volatilized generation exhaust gas of organic solvent) such as ester, alcohol, benzene, ketone, dimethylbenzene, first in paint
The volatile organic compounds such as benzene, ethylbenzene, styrene, formaldehyde；The heavy metal substances such as dissoluble lead, cadmium, chromium, mercury.Therefore it paints
It must be provided with emission-control equipment in workshop, handle the various exhaust gas rich in toxin generated in painting process.
Due to containing paint aerosol during paint lacquer spraying technique in the exhaust gas of generation, paint aerosol has certain adherency
Property, when spraying cleaning using spray column, paint aerosol is readily adsorbed in the filler of spray column, is caused filler to block, is influenced to spray
Effect is drenched, simultaneously as containing a large amount of VOC in exhaust gas, existing packed tower is difficult to effectively remove VOC, after causing spray
Shower water in contain a large amount of organic solvent, need to carry out secondary wastewater processing, increase cost.
Summary of the invention
To solve the above problems, the present invention provides a kind of painting workshop spray tower for waste gas.
The invention provides the following technical scheme:
A kind of painting workshop spray tower for waste gas, the spray column include the discharge chamber, spray chamber, filler being from top to bottom sequentially distributed
Room, inlet plenum, Sewage treatment room, expansion chamber；The inlet plenum connects air inlet pipe, and the air inlet pipe side wall is equipped with blow vent, institute
Air inlet pipe is stated equipped with activated carbon adsorption layer；Filler is equipped in the filler chamber；The spray chamber includes spray tube, spray head,
The discharge chamber is equipped with escape pipe, and the Sewage treatment room connects soda acid tank, additive tank, and Sewage treatment room side is equipped with
PH detection window, level sensing window, the PH detection window is interior to be equipped with PH detector, and the level sensing window is equipped with liquid level
Meter；Sedimentation plate is equipped in the expansion chamber, the expansion chamber bottom is equipped with removable side panel.
Further, the removable side panel connects unloading valve.Unloading valve can convenient for discharging ash, while as needed, can will
Unloading valve connects totally enclosed type chain mat machine, and further automatic words unload ash.
Further, the sedimentation plate is Multilayer Network panel.Grid sedimentation plate can uniformly settle the dust of spray washing.
Further, the spray head is located at spray column center.
Further, ultraviolet lamp tube, photochemical catalyst plate are equipped in the Sewage treatment room, the ultraviolet lamp tube setting is useless
At the top of water recovery room, the photocatalysis pole plate is connected on the locular wall of Sewage treatment room.Under the action of ultraviolet lamp tube, realization has
Organic gas is resolved into water and carbon dioxide by the decomposing organic gas of effect, realizes the processing of exhaust gas.
The present invention is compared with prior art: the present invention realizes the exhaust gas that effective spray washing painting workshop generates, purification
Harmful substance in exhaust gas avoids paint aerosol blocking filler, adsorbs paint in effective air inlet pipe, and due to air inlet pipe side wall
The paint of absorption can be washed when spraying water spray equipped with blow vent, realize that the sorbent circulation in air inlet pipe uses；
To realize the effect for avoiding paint blocking filler, when exhaust gas passes through in filler, it is possible to increase contact of the exhaust gas with shower water
Area realizes efficiently dust, pernicious gas, harmful liquid in rapidly scrubbing exhaust gas, removes VOC, meanwhile, it is useless after removing
Contain a large amount of harmful substance in water, Sewage treatment room connects soda acid tank, additive tank, realizes the PH for adjusting waste water, and pass through
It adds chemical reagent or microbial bacteria is realized to the detoxication in waste water；Treated waste water settles powder by expansion chamber
Dirt, effective dedusting.
