Water curtain type paint mist filter

Abstract

The invention relates to a water curtain type paint mist filter which is mainly formed by connecting a water tank 1, a gas collecting box 11 and an air exhaust plenum box 8 in series, wherein a gas-water mixing channel 12 is formed in the water tank 1; a diversion rail 5 and a porous water baffle 7 are arranged in the gas collecting box 11; and the air exhaust plenum box 8 is directly and externally connected with an exhaust fan. Paint mist is collided with a water curtain under the suction action of the exhaust fan, particulate matters are completely cleaned in the water, and gas and the water are separated under the action of the diversion rail 5. The separated gas penetrates through the porous water baffle 7 and an activated carbon filter plate 10 to be filtered and is discharged into the atmosphere; and the separated water is drained to an upper flashing plate 3 and a lower flashing plate 2 through an overflow tank 4 so as to form the water curtain, and the recirculation is formed. The water curtain type paint mist filter has the advantage of being a pump-free filter, the exhaust fan in a system can be directly utilized as unique power, and the energy consumption is low; and the filter is simple in structure and flexible to mount, sewage discharge is avoided, and the purification efficiency of the paint mist is over 95 percent.

Description

technical field [0001] The invention relates to a paint mist filter in painting and spraying equipment, in particular to a water curtain type paint mist filter. Background technique [0002] In the painting industry, the workpiece needs to be painted. During the painting process, a large amount of paint mist will be generated in the spray booth, which will not only pollute the working environment, but also cause great harm to the operators. Many operators will suffer from occupational diseases. Therefore, the treatment of paint mist in the painting process is a very important and indispensable work. [0003] At present, in the painting industry, most of the paint mist treatment filters are used to treat the paint mist. For the spraying of some large and medium-sized workpieces, the paint mist treatment filter generally adopts a paint mist filter cotton filter or a water spin paint mist filter. These paint mist filters must have the basis of production equipment such as wat...

Problems solved by technology

For the spraying of some large and medium-sized workpieces, the paint mist treatment filter generally adopts a paint mist filter cotton filter or a water spin paint mist filter. These paint mist filters must have the basis of production equipment such as water pumps, which not only greatly increases the investment cost. Moreover, there is sewage discharge, causing secondary pollution to the environment
