1. Product overview of acid mist scrubber
Acid mist scrubber is also called acid mist treatment tower, acid mist purification tower, and acid mist absorption tower. At present, acid mist scrubbers are mainly used to treat corrosive industrial gases (such as acidic and alkaline waste gas), and acid mist scrubbers mostly use liquid absorption to treat waste gas. At present, it has independently developed acid-base waste gas purification processes and equipment with high purification efficiency, simple operation and management, and long service life. The acid mist scrubber produced by our company combines the advantages of similar acid mist treatment towers at home and abroad, adopts multi-stage rotating spray absorption, and optimizes the technical parameters of the packing layer and the tower body. The acid mist absorption tower produced by our company has the characteristics of simple structure, low energy consumption, high purification efficiency, and wide application range. The acid mist absorption tower can effectively remove hydrogen chloride gas (HCl), hydrogen fluoride gas (HF), ammonia (NH3), sulfuric acid mist (H2SO4), chromic acid mist (CrO3), hydrogen cyanide gas (HCN), alkaline steam ( NaOH), hydrogen sulfide gas (H2S), formalin (HCHO) and other water-soluble gases.
2. Working principle of acid mist scrubber
The acid mist exhaust gas is introduced into the purification tower through the air duct, passes through the packing layer, and passes through the packing layer from bottom to top; the circulating absorbent is evenly sprayed into the backing layer from the top of the tower through the liquid distributor, flows down the surface of the backing layer, and enters the circulation Water tank. Due to the continuous contact between the ascending gas and the descending absorbent in the filler, the liquid concentration in the ascending gas is getting lower and lower. The exhaust gas and the sodium hydroxide absorption liquid undergo a gas-liquid two-phase complete contact absorption and neutralization reaction. After the acid mist exhaust gas has been treated, it will be dehydrated and defogged by a defogging board and then discharged into the atmosphere by a fan. The absorption liquid is pressurized by a water pump at the bottom of the tower, sprayed down from the top of the tower, and finally returned to the tower base for recycling. The purified acid mist exhaust gas meets the emission requirements and is lower than the national emission standards.
3. Selection of acid mist scrubber
The selection of the acid mist absorption tower is determined according to the nature, processing capacity and processing requirements of the exhaust gas. Our goal is to ensure the emission of waste gas pollutants and establish a harmless and clean production process. Therefore, when selecting an acid mist scrubber, taking into account the temperature and concentration of the exhaust gas and the corrosiveness of exhaust gas treatment, the acid mist absorber is generally made of PP board and FRP, and the equipment should be optimized and combined to form a high efficiency, low cost, and low energy. Consumption processing technology.
4. The structure of the acid mist scrubber
The acid mist absorption tower combines the tower body, absorption liquid tank, circulating pump and absorption liquid pipeline system into a complete set of equipment.
5. Application range of acid mist scrubber
The acid mist absorption tower is suitable for the production process of the chemical industry, light industry, printing and dyeing, medicine, steel, machinery, electronics, instrument, electroplating, etc. (H2SO1), hydrogen chloride (HC1), hydrogen fluoride (HF), chromic acid mist (CrO3), cyanide Hydrogen sulfide (HCN), hydrogen sulfide (H2S), ammonia (NH3), alkali vapor and other water-soluble gases, using sodium hydroxide as the absorbing and neutralizing liquid, the solution concentration is 2-6%, and the purification efficiency is above 95%.
