Exhaust gas purification tower equipment principle: BJT mist purification tower for corrosive gases (such as acid and alkaline waste gas) governance, the current use of liquid absorption treatment. The key to the treatment of the waste gas by liquid absorption is the selection of purification equipment. Hoffen exhaust gas purification tower said the process and the product has the advantages of simple structure, low energy consumption and high purifying efficiency and wide application range, can effectively remove the hydrogen chloride gas (HCl), hydrogen fluoride (HF), ammonia (NH3), sulfuric acid mist (H2SO4), chromium acid (CrO3), hydrogen cyanide gas (HCN) and alkali (NaOH), hydrogen sulfide (H2S), Faure Marin (HCHO) and water soluble gas. The introduction of acid mist exhaust purification tower by air duct, exhaust gas passes through the filler layer, and sodium hydroxide absorption liquid two-phase full contact absorption neutralization reaction, acid mist emissions after cleaning, the demisting plate dehydration fog by the fan into the atmosphere. The absorption liquid is sprayed at the bottom of the tower after the booster of the water pump, and finally returns to the bottom of the tower to be recycled. Acid mist emissions after purification reached Guangdong local discharge standard requirements, lower than the national emission standard.

Hongfeng said exhaust gas purification tower for purifying waste gas by adopting a packing tower, governance suitable for continuous and intermittent emissions; simple process, management, operation and maintenance is convenient, will not have any effect on the workshop production; wide application range, can also purify many kinds of pollutants; low pressure drop, high operating flexibility. The fog removal performance and has very good; the tower body can be used according to the actual situation of FRP/PP/PVC and other materials; Bauer ring filler with high efficiency and low resistance, can thoroughly remove the smell of gas, and other harmful substances.

Waste gas purification tower application occasions: the process and equipment can be widely used in chemical, electronic, metallurgical, electroplating, textile (chemical fiber), food, machinery manufacturing process emissions of acid, alkaline waste gas purification treatment. Such as seasoning food, acid making, pickling, electroplating, electrolysis, storage battery, etc..
