Working principle: Acidic gas enters the acid mist purification tower along the tangential direction from the inlet below the tower body. Under the power of the ventilation fan, it quickly fills the space in the inlet section and then uniformly rises through the equalization section to the first stage packing absorption section. On the surface of the filler, acidic substances in the gas phase react chemically with alkaline substances in the liquid phase, producing substances (mostly soluble acids) that flow into the lower storage tank along with the absorbent. The partially absorbed acidic gas continues to rise and enter the first spray section. In the spray section, the absorbing liquid is sprayed at high speed from uniformly distributed nozzles, forming countless small droplets that are fully mixed and in contact with the gas, continuing to undergo chemical reactions. Then, the acidic gas rises to the secondary packing section and spray section for a similar absorption process as the first stage. The density of the secondary and primary nozzles is different, the spray pressure is different, and the range of absorbed acidic gas concentration is also different. The process of contact between the spray section and the packing section is also a process of heat and mass transfer. By controlling the flow rate and retention time of the empty tower, the adequacy and stability of this process are ensured.

The upper part of the tower is the defogging section, where the absorption liquid droplets trapped in the gas are removed and returned to the lower water tank. The acid in the water tank is neutralized by an automatic addition system. The processed clean air is discharged into the atmosphere through the exhaust pipe at the upper end of the acid mist purification tower. Applicable industries: Chemical, light industry, printing and dyeing, steel, machinery, electronics, instrumentation, electroplating and other industrial sectors emit sulfuric acid, nitric acid, hydrochloric acid, hydrofluoric acid and other tail gases, as well as acidic gases such as sulfur oxides (SOx), nitrogen oxides (NOx), carbon oxides (CO, CO2) during production processes. JYSJ series acid mist purification equipment can achieve satisfactory results.
