Spray purification tower

Spray tower paint mist treatment equipment for corrosive gases (such as acid, alkaline waste gas) treatment, the current use of liquid absorption method of governance. The key to the treatment of the waste gas by liquid absorption method is the choice 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. The process and products integrate the advantages of similar purification towers at home and abroad, multi-stage rotary spraying and absorption, and at the same time optimize the technical parameters of the packing layer and tower body, with the characteristics of simple structure, low energy consumption, high purification efficiency and wide application range, it can effectively remove water-soluble gases such as hydrogen chloride gas (HCI), hydrogen fluoride gas (HF), ammonia gas (NH3), sulfuric acid mist (H₂ S04), chromic acid mist (CrO3), hydrogen cyanide gas (HCN), alkali vapor (NaOH), hydrogen sulfide gas (H₂ S), formalin (HCHO), etc.

Spray purification tower

工 作 原 理 / The  working  principle  of


The paint mist exhaust gas is introduced into the purification tower through the air pipe and passes through the packing layer. The exhaust gas and sodium hydroxide absorption liquid are fully contacted and absorbed and neutralized. After purification, the paint mist exhaust gas is dehydrated and defogged by the defogging board and discharged into the atmosphere by the fan. The absorption liquid is sprayed down at the top of the tower after being pressurized by a water pump at the bottom of the tower, and finally refluxed to the bottom of the tower for recycling. The purified acid mist exhaust gas meets the emission requirements and is lower than the national emission standard.

结 构 特 点 /Structural   characteristics


The paint mist spray tower is made of PP material and stainless steel material, and the structure is divided into single tower body and double tower body. The circular tower body is connected by flange segments. It is specifically composed of liquid storage tank, tower body, air inlet section, spray layer, packing layer, cyclone demisting layer, observation window, air outlet, etc.

 

Scope of application/Scope of applicatior


Spray spray tower applications: this process and equipment can be widely used in chemical, electronics, metallurgy, electroplating, textile (chemical fiber), food, machinery manufacturing and other industries in the process of acid and alkaline waste gas purification treatment. Such as seasoning food, acid, pickling, electroplating, electrolysis, batteries, etc. There are also a variety of purification tower to choose from: waste gas absorption tower, spray tower, alkali washing tower, tail gas purification tower, activated carbon adsorption tower and other series of purification tower spray tower, washing tower, alkali washing tower, biogas desulfurization tower.
