Embodiment Construction

[0019] The present invention will be further described below in conjunction with the examples.

[0020] like figure 1 Shown is a hybrid dust removal device for removing paint mist from spray paint exhaust gas, which includes a venturi filter 2 , a cyclone filter 3 , a bag filter 7 , a fan 8 , a circulating water pump 5 and a circulating water tank 4 .

[0021] Among them, one end of the venturi dust collector 2 is the air inlet 2-2 for the entry of paint spraying waste gas, and the other end is the water-air mixture outlet 2-3. The water-air mixture outlet 2-3 of the venturi dust collector is connected to the cyclone. The water-air mixture inlet 3-1 on the side of the dust collector is connected, the dust outlet 3-3 at the lower end of the cyclone dust collector is located in the circulating water tank 4, and the air outlet 3-2 at the upper end of the cyclone dust collector is connected with the air inlet of the bag filter 7-4 is connected, the air outlet 7-5 of the bag filte...

Abstract

The invention discloses a mixed dust removal device for removing paint mist in spray paint waste gas. The mixed dust removal device comprises a Venturi tube dust remover, a cyclone dust remover, a bagfilter, a fan, a circulating water pump and a circulating water tank. One end of the Venturi tube dust remover is provided with a gas inlet for enabling spray paint waste gas to flow in, the other end of the Venturi tube dust remover is provided with a water-gas mixture outlet connected with a water-gas mixture inlet of the cyclone dust remover, a dust discharge outlet formed in the lower end ofthe cyclone dust remover is formed in the circulating water tank, an exhaust port at the upper end of the cyclone dust remover is connected with a gas inlet of the bag filter, a gas outlet of the bagfilter is connected with a gas inlet of the fan, gas can be exhausted from a gas outlet of the fan finally, a liquid inlet of the circulating water pump is communicated with the circulating water tank, and a liquid outlet of the circulating water pump is connected with a spraying liquid inlet of the Venturi tube dust remover. Paint mist and other dust particualte matter in spray paint can be effectively removed.

Description

technical field [0001] The invention relates to dust removal equipment, in particular to a hybrid dust removal equipment used for removing paint mist in paint spraying waste gas. Background technique [0002] The exhaust gas discharged from the painting and spray booth contains a large amount of paint mist and various solid particles. Due to the large content of paint mist, the number of tiny particles is large. At present, a single method is used to treat the exhaust gas discharged from the painting and spray booth, but it is difficult to clean up, which increases the operating cost of subsequent exhaust gas treatment. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a hybrid dust removal device for removing paint mist in the exhaust gas of painting, which can efficiently remove dust particles such as paint mist in painting and spraying. [0004] To solve the above-mentioned technical problems, the technical sche...
