Equipment principle:For the treatment of corrosive gases (such as acid and alkaline waste gases), liquid absorption method is currently commonly used. The key to using liquid absorption method to treat this exhaust gas lies in the selection of purification equipment. At present, our company has independently developed acid and alkaline waste gas purification processes and equipment with high purification efficiency, simple operation and management, and long service life. This process and product have the characteristics of simple structure, low energy consumption, high purification efficiency, and wide applicability. It can effectively remove water-soluble gases such as hydrogen chloride gas (HCl), hydrogen fluoride gas (HF), ammonia gas (NH3), sulfuric acid mist (H2SO4), chromic acid mist (CrO3), hydrogen cyanide gas (HCN), alkali vapor (NaOH), hydrogen sulfide gas (H2S), formalin (HCHO), etc. The acid mist exhaust gas is introduced into the purification tower through the air duct, passes through the packing layer, and undergoes gas-liquid two-phase contact absorption and neutralization reaction with the sodium hydroxide absorption solution. After purification, the acid mist exhaust gas is dehydrated and defogged by the defogging plate before being discharged into the atmosphere by the 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 refluxed to the bottom for recycling. The purified acid mist exhaust gas meets the emission requirements of the local emission standards in Guangdong Province and is lower than the national emission standards.

Equipment features:This equipment uses a packed tower to purify exhaust gas, which is suitable for the treatment of continuous and intermittent emissions of exhaust gas; The process is simple, and the management, operation, and maintenance are quite convenient and concise, without causing any impact on the production of the workshop; Widely applicable and capable of purifying multiple pollutants simultaneously; Low pressure drop, high operational flexibility, and excellent defogging performance; The tower body can be made of materials such as FRP/PP/PVC according to the actual situation; The packing adopts efficient and low resistance Ball rings, which can thoroughly remove odors, harmful substances, etc. from the gas.

Structural form:This equipment is divided into single tower and double tower. It adopts a circular tower body and is connected in sections with flanges. Specifically, it consists of a liquid storage tank, tower body, inlet section, spray layer, packing layer, cyclone defogging layer, outlet cone cap, observation hole, etc.

Application scenarios:This process and equipment can be widely used for the purification and treatment of acidic and alkaline waste gases emitted in industries such as chemical, electronic, metallurgical, electroplating, textile (chemical fiber), food, and machinery manufacturing. Such as seasoning food, acid making, pickling, electroplating, electrolysis, batteries, etc.
