Device for removing paint mist

Abstract

The invention relates to the field of waste gas treatment, in particular to a device for removing paint mist. The device comprises a shell, a flow guide mechanism, a water spraying device, an adjusting device, a filtering device, a wastewater pump, a centrifugal pump, a waste gas inlet, a waste gas outlet and a maintenance area, and the waste gas outlet is connected with an exhaust fan. When paintmist waste gas passes through the flow guide mechanism, the paint mist waste gas is mixed with water, which contains a treating agent and is sprayed by the water spraying device. The gas-water mixture forms a high negative pressure vacuum area when passing through the outlet of the flow guide mechanism. Because the gas phase / liquid phase accelerated speeds are different; a part of paint mist particles fall into water; the other part of the paint mist enters a second chamber through the a through hole in a partition plate; the waste gas passes through the filtering device and moves to the waste gas outlet, the water spraying device sprays water containing a treating agent downwards, and thus the paint mist waste gas is rapidly condensed when passing through the filtering device and collected in a storage box. The device is simple in structure, convenient to maintain and operate, and safe and reliable, the problem that a conventional filtering device is easy to block is solved, and theefficiency is improved.

Description

technical field [0001] The invention and the field of waste gas treatment, in particular, relate to a device for removing paint mist. Background technique [0002] With the prominence of our country's environmental protection issues, exhaust emissions have risen to the point of being strictly controlled. At present, the treatment of paint mist is mainly divided into two types: wet type and dry type. Among them, wet type treatment technology is widely used, but there is a problem that the increase of humidity in the spraying space and the humidity requirements of the painting environment are in violation of the problem of wet treatment. It is easy to block, the equipment is prone to explosion risk, the filter device needs to be replaced frequently, the treatment cost is high and the treatment efficiency is low. [0003] The technical problem to be solved by the present invention is that the filter device of the existing paint mist removal device is easily blocked and needs t...
