Spraying tower for paint mist waste gas treatment

Abstract

The invention discloses a spraying tower for paint mist waste gas treatment. The spraying tower comprises a tower body, a water storage tank, an air inlet, an air outlet, a fan and a circulating waterpump, wherein the water storage tank is positioned under the tower body; the air inlet is positioned under the tower body; the air outlet is positioned above the tower body; the fan is arranged besides the air inlet; the circulating water pump is connected with the water storage tank; a paint mist decomposing agent and a paint mist capturing agent are added into circulating water for spraying waste gas treatment. The spraying tower has the advantages that by arranging a plurality of filler layers and a plurality of spraying devices, paint mist in waste gas can be effectively removed, and thetreatment quality of the waste gas is improved; by adding the paint mist decomposing agent into the circulating water, the sticking of the paint mist to the inner wall of the spraying box can be effectively prevented; floating slag of the paint mist can be favorably treated, the usage cycle of the circulating water is prolonged, and the damage to equipment is reduced.

Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to a spray tower for paint mist waste gas treatment. Background technique [0002] At present, a simple spray box is generally used for paint mist pretreatment, that is, multiple spray devices are installed in a square box, and the circulating water and waste gas sprayed out by the spray device directly pass through the spray box to mix with water vapor, and part of the paint mist is trapped in the spray box. inside the box. Due to the poor paint mist removal effect of this kind of simple spray box, the water vapor mixed in the exhaust gas enters the activated carbon adsorption tower together, causing the activated carbon to become wet and invalid, so it cannot be widely used. Moreover, the paint mist will adhere to the equipment, pipes and the inside of the pump body. After a period of use, it will cause blockage of waterways and airways, making it difficult to clean up, causing...

Problems solved by technology

Due to the poor paint mist removal effect of this simple spray box, the water vapor mixed in the exhaust gas enters the activated carbon adsorption tower together, causing the activated carbon to become wet and invalid, so it cannot be widely used

Moreover, the paint mist will adhere to the equipment, pipes and the inside of the pump body. After a period of use, it will cause blockage of water and air passages, making it difficult to clean up, resulting in the failure of the purification treatment system to operate normally, affecting the effect of waste gas treatment, and affecting the spraying effect. damage to the box and affect its service life
