PP acid mist purification tower
For the treatment of corrosive gases (such as acid and alkaline exhaust gas), the PP acid mist purification tower currently adopts the liquid absorption method. The key to using liquid absorption to treat this exhaust gas is the choice of purification equipment. At present, our company has independently developed acid and alkaline exhaust gas purification processes and equipment with high purification efficiency, simple operation and management, and long service life. The process and product have the characteristics of simple structure, low energy consumption, high purification efficiency and wide application range, and can effectively remove hydrogen chloride gas (HCl), hydrogen fluoride gas (HF), ammonia gas (NH3), sulfuric acid mist (H2SO4), chromium Water-soluble gases such as acid mist (CrO3), cyanohydrin gas (HCN), alkali vapor (NaOH), hydrogen sulfide gas (H2S), and formalin (HCHO). The acid mist exhaust gas is introduced into the purification tower through the air duct. After the filler layer, the exhaust gas and the sodium hydroxide absorption liquid are brought into full gas-liquid two-phase absorption and neutralization reaction. The fan is discharged into the atmosphere. The absorption liquid is sprayed down on the top of the tower after being pressurized by a pump at the bottom of the tower, and finally returned to the bottom of the tower for recycling. The purified acid mist exhaust gas meets the emission requirements of Guangdong Province's local emission standards and is lower than the national emission standards.
Equipment features: PP acid mist purification tower This equipment adopts a packed tower to purify the exhaust gas, which is suitable for the continuous and intermittent exhaust gas treatment; the process is simple, the management, operation and maintenance are quite convenient and concise, and will not affect the production of the workshop; Wide range of application, can purify multiple pollutants at the same time; low pressure drop, large operating flexibility, and good defogging performance; the tower can be made of FRP / PP / PVC and other materials according to the actual situation; Low-resistance Bower ring can completely remove odors and harmful substances in the gas.
Structure: PP acid mist purification tower This equipment is divided into single tower and double tower. It adopts a circular tower body and is connected in sections by flanges. Specifically, it consists of a liquid storage tank, a tower body, an air inlet section, a spray layer, a filler layer, a swirling demister layer, an air outlet cone cap, and an inspection hole.
Application: This process and equipment can be widely used in the purification of acid and alkaline exhaust gas discharged in the process of chemical, electronics, metallurgy, electroplating, textile (chemical fiber), food, machinery manufacturing and other industries. Such as seasoning food, acid-making, pickling, electroplating, electrolysis, batteries, etc.
