Description

A kind of paint spray booth

Technical field

The invention belongs to and paint the field of spraying paint, especially relate to a kind of paint spray booth.

Background technology

In existing paint spray booth, coating cloud is generally by cascade absorption, but still have after the cascade absorption 30% in addition more coating clouds be not adsorbed, be discharged into contaminated air in the atmosphere, also affect the healthy of workman simultaneously; The waste water that adsorption process produces directly is discharged in the environment contaminated environment by pipeline.

Summary of the invention

The problem to be solved in the present invention provides a kind of paint spray booth, especially is fit to middle-size and small-size painting workpieces and uses.

For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of paint spray booth, comprise the chamber body, water screen apparatus, air-supply arrangement, air intake device, water circle device, tank, the water shower device, Turbogrid plates, platform sprays paint, discharge outlet, wastewater treatment equipment, water screen apparatus is by water curtain plate, overflow launder forms, air-supply arrangement is by air compressor, screen pack, air supply duct forms, air intake device is by air exhauster, exhaust duct, active carbon filtering device forms, the water shower device is built in the exhaust duct, be provided with drainage plate in the exhaust duct, active carbon filtering device is installed in the exhaust duct upper orifice, water circle device is by water pump, water supply line forms, water supply line supplies water for respectively overflow launder and water shower device, tank is connected with the exhaust duct lower nozzle, be connected with the exhaust duct wall of a side of tank has the waveform ladder, and discharge outlet connects tank and wastewater treatment equipment.

Further, described exhaust duct bottom becomes smooth S type.

Further, described water shower device is built in the S type position of described exhaust duct.

Further, described water shower device has more than two.

Further, described water shower device is Multi-row-tube cellular type shower nozzle.

Further, described water curtain plate is the tangent shape water curtain plates of two circular arcs.

Advantage and good effect that the present invention has are: owing to adopting technique scheme, capture rate that can the Effective Raise coating cloud, on existing cascade basis, increase the spray absorption of water shower device, drainage plate in the exhaust duct, make the water of spray form cascade, the water that flows downward bumps against with the coating cloud that upwards flows, and makes the absorption of coating cloud more complete; Waste gas is through the charcoal absorption at exhaust duct road junction, and organic exhaust gas is adsorbed, and makes the gas that is discharged in the atmosphere safer, environment protection; Water drenches water and the cascade water all is pooled to tank, can be recycling, and after waste water is processed through wastewater treatment equipment, again as recirculated water, reduce water consumption; The wall waviness of tank one side is stepped, the recirculation water from water shower device and cascade is had the effect that stops sedimentation, can remove the part residue in the waste water, is convenient to the water circuit utilization.

The specific embodiment

As shown in Figure 1, the present invention includes chamber body 1, water screen apparatus, air-supply arrangement, air intake device, water circle device, tank 7, water shower device 19, Turbogrid plates 18, platform 3 sprays paint, discharge outlet 9, wastewater treatment equipment, described water screen apparatus is by water curtain plate 2, overflow launder 4 forms, described air-supply arrangement is by air compressor 15, screen pack 17, air supply duct 16 forms, described air intake device is by air exhauster 14, exhaust duct 12, active carbon filtering device 13 forms, described water shower device 19 is built in the exhaust duct 12, be provided with drainage plate 11 in the described exhaust duct 12, described active carbon filtering device 13 is installed in described exhaust duct 12 upper orifice, described water circle device is by water pump 8, water supply line 5 forms, described water supply line 5 supplies water for respectively overflow launder 4 and water shower device 19, described tank 7 is connected with described exhaust duct 12 lower nozzle, be connected with described exhaust duct 12 wall of a side of described tank 7 has waveform ladder 6, and described discharge outlet 9 connects described tank 7 and described wastewater treatment equipments 10.

Further, described exhaust duct bottom becomes smooth S type.

Further, described water shower device has more than two.

The course of work of this example: during use, open air compressor 15 and air exhauster 14, the compressed machine of atmosphere is processed by air supply duct 16 and through filter screen 17 and is filtered backward indoor air-supply, can reduce the impurity of ambient atmosphere, tank 7 injects suitable quantity of water, open water pump 8, water pump 8 is supplied water to overflow launder 4 and water shower device 19 by water supply line 5, after overflow launder 4 water are full, water overflows to circular arc water curtain plate 2 and forms cascade, the workman that sprays paint stands in the opposite side of relative water curtain plate 2 one sides of the platform that sprays paint, and the object that is placed on the platform 3 that sprays paint is sprayed paint, and the effect that the coating cloud that produces in the painting process is compressed air flows downward and adsorbed by cascade; Part coating cloud is adsorbed by cascade, flow in the tank 7 by Turbogrid plates 18, the coating cloud that is not adsorbed of a part pass Turbogrid plates 18 and through tank 7 in exhaust duct 12, coating cloud in the exhaust duct 12 is after 19 absorption of water shower device, waste gas is discharged in the atmosphere by air exhauster 14 after absorbent charcoal adsorber 13 is processed, and effectively reduces organic exhaust gas to the pollution of atmosphere; Water shower device 19 is porous shell and tube shower nozzle, water shower device 19 water sprays, form less cascade by drainage plate 11, the water that flows downward bumps against with the coating cloud that upwards flows, because exhaust duct 12 bottoms become the S type, can increase the collision of coating cloud and tube wall and cascade, and coating cloud there is certain deceleration effect, make the absorption of coating cloud more complete, the number of drainage plate 11 can be regulated according to output, the water that flows out from cascade and the water of water shower device 19 ejections are back to tank 7, and recirculation water is through the sedimentation that stops of the waveform ladder 6 of tank 7, and the residual quarrel of part is removed, the water that tank is 7 li can be for recycling, repeatedly after the circulation, the paint spray booth quits work, and opens discharge outlet 9, waste water is discharged into wastewater treatment equipment 10 through discharge outlet 9, waste water after treatment is discharged into again tank 7, for recycling, to reach pollution and the water-saving purpose that reduces environment.

Above one embodiment of the present of invention are had been described in detail, but described content only is preferred embodiment of the present invention, can not be considered to be used to limiting practical range of the present invention.All equalizations of doing according to the present patent application scope change and improve etc., all should still belong within the patent covering scope of the present invention.
