The working principle of the spray tower

The acidic exhaust gas enters the purification tower through the ventilation duct. After passing through the packing layer, the exhaust gas and the sodium hydroxide absorbent come into full contact with the gas and liquid, absorbing and neutralizing the gas. The purified acidic exhaust gas is dehydrated by the ash plate and then discharged to the atmosphere by the fan. After pressurizing the bottom of the tower with a pump, the absorbent is sprayed onto the top of the tower and then recycled to the bottom of the tower. The purified acidic exhaust gas meets the national emission standards.

What kind of chemicals are added to the spray tower?

The reagents in the spray tower are generally strong acids (sulfuric acid), strong bases (sodium hydroxide), and strong oxidants (sodium hypochlorite).

The water treatment agent for the spray painting tower is the paint mist agglomerating agent AB. Here, the paint mist agglomerating agent A decomposes the paint mist that falls onto the spray painting surface through the polymer medium, breaking down the paint mist and forming it in large quantities. Under the action of the paint mist condensing agent B, the paint residue particles aggregate or concentrate. Thus, the circulating water treated by the spray painting tower with the paint mist coagulant has no pipe blockage or odor, and also solves the water pollution problem of the spray painting tower, allowing for recycling.

The principle is mainly based on the components of the odor. Reuse strong acids (sulfuric acid), strong bases (sodium hydroxide), and strong oxidants (sodium hypochlorite) as the spray solution. Then, the odor molecules collide with the odor components in the gaseous phase of the waste gas and are rapidly transferred to the liquid phase. After neutralization, the odor components are effectively removed through the chemical reaction of the chemical agents and the odor components.

The advantages of the spray tower are as follows

The dust removal and desulfurization efficiency is very high. When using alkaline washing water, the desulfurization efficiency can reach 85%.

2. The equipment occupies a small space and is easy to install.

3. The water and electricity consumption indices are relatively low.

4. Corrosion-resistant, without wear, long service life.

5. The equipment operates reliably and is easy to maintain.
