Technical Field

The utility model relates to the technical field of environmental protection, in particular to an acid mist gas recycling device.

Background

Acid mist generally refers to a mist of acids. The particles of the acid mist in the air are very small, smaller than the particles of the water mist, higher than the humidity of smoke, and the particle size is 0.1-10 mu m, so that the acid mist is a substance between the smoke and the water mist, and has stronger corrosiveness. Including acid mist formed by inorganic acids such as sulfuric acid, nitric acid, hydrochloric acid and the like and organic acids such as formic acid, acetic acid, propionic acid and the like.

The formation mechanism of acid mist is mainly two kinds: one is that the acid liquid surface evaporates, the acid molecule enters the air, and the acid molecule is condensed with the water in the air to form fog drops; the other is that the acid solution has chemical reaction, so that bubbles are formed to float up to the liquid level and then burst, and liquid drops are carried out.

Acid solution is often used in modern industrial production, acid mist is inevitably generated, and the acid mist is discharged into the air without treatment, so that the environmental safety is seriously affected. At present, wet electrostatic defogging dust removal equipment is often used, dust particles and acid mist droplets are charged, then the dust and the mist droplets are gathered on a polar plate under the action of an electrostatic field, and then water is sprayed on the polar plate to realize dust removal and defogging.

However, the above patent still has the problem that the collecting plate is not fully utilized and can not be timely cleaned, and when exhaust gas dust particles and mist enter the treatment device from the air inlet, the exhaust gas dust particles and the mist can be preferentially adsorbed to the collecting plate and are close to the air inlet area, so that the collecting plate is far away from the air inlet area and can not be fully utilized, and then water spray cleaning is difficult to timely clean up dirt, so that the adsorption efficiency of the collecting plate is affected.
