Absorption tower Principle of equipment： For the treatment of corrosive gases (such as acid and alkaline waste gas) liquid absorption method is mostly used at present. Using liquid absorption to treat the waste gas is the key to the selection of purification equipment. At present our company has independently developed acid and alkaline waste gas purification process and equipment with high purification efficiency simple operation and management and long service life. The process and products have the characteristics of simple structure low energy consumption high purification efficiency and wide application range can effectively remove hydrogen chloride gas (HCl) hydrogen fluoride gas (HF) ammonia gas (NH3) sulfuric acid fog (H?SO). Chromic acid mist (CrO,) cyanuric acid gas (HCN) alkali vapor (NaOH) hydrogen sulfide gas (H2S) formalin (HCHO) and other water-soluble gas. Acid fog exhaust gas is introduced into the purification tower by the air duct and through the packing layer the exhaust gas and sodium hydroxide absorption liquid are fully contacted absorbed and neutralized. After purification the acid fog exhaust gas is dehydrated and defogged by the defogging plate and discharged into the atmosphere by the fan. The absorption liquid is pressurized by the pump at the bottom of the tower and sprayed down at the top of the tower and finally returned to the bottom of the tower for recycling. The purified acid fog exhaust gas meets the emission requirements of Guangdong provincial emission standards lower than the national emission standards.
Equipment features：The equipment uses packed tower to purify the exhaust gas suitable for continuous and intermittent exhaust gas treatment; Simple process management operation and maintenance is quite convenient and simple will not cause any impact on the production of the workshop; Wide range of application can simultaneously purify a variety of pollutants; Low pressure drop large operation elasticity and has good defogging performance; The tower body can be made of FRP/stainless steel /PP plastic /PVC plastic material according to the actual situation; The packing uses the Pall ring with high efficiency and low resistance which can completely remove the odor and harmful substances in the gas
Structure form：The equipment is divided into single tower body and double tower body. The circular tower body is connected with flange segments. It is composed of liquid storage tank tower body air inlet section spray layer packing layer cyclone defogging layer air cone cap inspection hole and so on
Product use：This equipment can be widely used in chemical industry electronics metallurgy electroplating textile (chemical fiber) food machinery manufacturing and other industries in the process of acid alkaline waste gas purification treatment. Such as flavoring food acid pickling electroplating electrolysis battery and so on
