Spray painting exhaust gas purification towerOverview

The spray painting exhaust gas purification tower is a new generation of dry adsorption acidic exhaust gas purifier jointly developed by our company under the guidance of relevant design units, after the original BF, DGS, BSG alkaline wet acid mist purification towers. The purifier uses special adsorption fillers and is another novel purification equipment for treating various acidic exhaust gases such as nitrogen oxides (NOx), hydrochloric acid mist (HCL), sulfuric acid mist (H2SO4), and hydrofluoric acid (HF). It has high purification efficiency, compact structure, small footprint, corrosion resistance, good aging resistance, light weight, and is easy to install and transport. Compared with the alkaline wet purification tower, it has the following characteristics:

1. High adsorption purification efficiency;

2. Good temperature applicability;

3. Low operating costs, one-time addition of fillers, can meet long-term operation requirements;

4. Simple operation, management, and maintenance;

5. No secondary pollution is generated during operation;

6. It can purify and process multiple mixed acidic gases simultaneously.

Spray painting exhaust gas purification towerScope of Application

The spray painting exhaust gas purification tower has become suitable for acidic exhaust gas generated in low concentration, large quantities or intermittent explosive high concentration working environments, and its application fields are wide; It can be applied to occasions or factory workshops where acidic waste gases are generated, such as metallurgy, chemical engineering, machinery, electroplating, electronic component production, battery life, acid washing operations, laboratory emissions, etc.

Spray painting exhaust gas purification towerworking principle

The acidic exhaust gas is purified by the filling bed layer inside the purifier (filling materials are divided into YHI and YHII types according to the acidic medium), and the exhaust gas is uniformly adsorbed through the filling material. The treated exhaust gas is directly discharged into the atmosphere by the fan, and the purified exhaust gas meets the requirements of Table 2 of the Comprehensive Emission Standard for Air Pollution GB16297-1996.

Installation of spray painting exhaust gas purification tower equipment, replacement and treatment of adsorption fillers

There is a chemical reaction between the adsorption packing and acid containing waste gas, which occurs from the contact surface inward. Therefore, the adsorption efficiency gradually decreases over time. However, replacing the adsorption packing once can generally last for about a year. If the concentration of the waste gas is greater than 1000mg/m3 or higher, the service life of the adsorption packing will be correspondingly shortened. The replacement of the adsorption packing will be supplied by our company. The replaced adsorption packing can be disposed of at will without causing secondary pollution.
