Abstract

The invention provides a micro-nano high-efficiency painting mist purifying tower. The structure of the micro-nano high-efficiency painting mist purifying tower comprises Pall ring packing layers, a cyclone plate and a purification trough water tank; two Pall ring packing layers are distributed at the top of a water washing tower; the cyclone plate is arranged at the intermediate position of the water washing tower; a sand glass-shaped channel is formed between the cyclone plate and the Pall ring packing layers to form a two-stage impact spraying chamber; the purification trough water tank is arranged at the bottom end of the water washing tower; the outer side of the purification trough water tank is connected with water cycling systems; spraying pipelines are arranged below the Pall ring packing layers and the cyclone plate by the water cycling systems through connecting pipes. According to the micro-nano high-efficiency painting mist purifying tower, atomizing and spraying are performed by adopting micro-nano air bubble liquid; through a two-stage impact structure in the tower, fine paint mist particles form large particles through adsorption, adhesion and collision and are brought out by air-water mixed liquid. Paint slag floats, is adhered into a flake, and is fished out through an air floating purifying trough below the tower, and the removal rate reaches 95 to 98 percent.

Description

technical field [0001] The invention belongs to the field of paint mist purification, in particular to a micro-nano high-efficiency paint mist purification tower. Background technique [0002] At present, the spray paint exhaust gas pretreatment equipment generally adopts the process of ordinary circulating water spraying water washing tower and mechanical filter. Ordinary circulating water spray washing towers rely on the principle of collision between fine droplets of spray water and particles in the exhaust gas to remove paint slag in the exhaust gas, but the removal rate for micron-sized particles is very low, and the removal efficiency for paint mist is only 30%-40%. The currently used circulating water spraying water washing tower first has a low collision rate between spray water droplets and paint mist particles, and secondly, the specific surface area of ​​water mist particles in the tower is smaller than that of micro-nano bubbles.
