Filter for removing paint and dust

Abstract

The invention relates to a filter for removing paint and dust. The filter comprises a spraying apparatus and a fog-clearing apparatus, wherein the spraying apparatus comprises a housing and a motor mounted on the back surface of the housing; the fog-clearing apparatus comprises a fog-clearing barrel and a fog-clearing motor; a guiding plate is arranged at an exhaust port of the housing; a fog-breaking guiding ring is installed in the rear side of the guiding plate; the fog-breaking guiding ring is provided with a plurality of grid holes; the grid holes are inclined axially toward the exhaust port; a plurality of fog-splashing nets are installed in an exhaust pipe; the fog-splashing nets are in circle or pot shapes; and the edges of the fog-splashing nets are fixed with the inner wall of the exhaust pipe. With the filter, the smoke dust, the paint and toxic materials in a tail gas are mixed in water fog rapidly through the spraying apparatus; water drops are allowed to be atomized in the exhaust pipe; the tail gas is enabled to fully contact with the water fog; the water fog with impurities is removed by the fog-clearing apparatus; and finally pure gas is discharged. The filter has the advantages of simple structure and high purifying efficiency; and plays an active effect for protection of ecological environment.

Description

technical field [0001] The invention relates to a device for purifying and treating various tail gases, in particular to a purification and filtering device capable of removing smoke, paint and toxic substances in the tail gas discharge. Background technique [0002] With the development of industry, the discharge of all kinds of industrial waste gas is increasing day by day. Industrial waste gas often contains smoke and a large amount of toxic substances, which will not only pollute the environment and seriously affect the health of workers and residents around the factory, but also affect the ecological environment of the earth. Serious destruction. Existing waste gas treatment devices mainly spray water mist into the waste gas to mix the smoke and toxic substances in the waste gas into the water mist, but there is no good way to completely separate the water mist from the air flow, so Soot and toxic substances in the discharged gas still cannot be effectively removed. T...

AI Technical Summary

Problems solved by technology

The spraying effect of the spray device of this kind of equipment is not ideal, so the water mist and the exhaust gas cannot be fully contacted and mixed, and the fog trapping effect of the mist catcher is not ideal, and some water mist carrying smoke and toxic substances is still discharged.
