1、 Overview of Carbon Steel Spray Tower:
This device is an absorption type exhaust gas purification device. After entering the absorption tower, the exhaust gas is treated by gas-liquid reverse absorption method, that is, the liquid sprays down from the top of the tower in the form of mist (or small droplets), and the exhaust gas rises in the opposite direction from the middle of the tower to achieve gas-liquid contact. When the liquid flows through the packing layer, the exhaust gas comes into full contact with the liquid (washing solution) flowing on the surface of the packing layer, so that the pollutants contained in the exhaust gas are fully absorbed. After washing and absorption, the waste liquid is collected in a collection tank and then discharged into the wastewater system for treatment. Spray washing can simultaneously cool the exhaust gas and remove particles from the exhaust gas. After absorbing and purifying the gas, it is treated in the dehazing section and discharged into the atmosphere.

2、 Working principle
The washing solution is atomized into small droplets through a nozzle and evenly sprayed downwards. The exhaust gas enters from the lower part of the packed absorption tower and flows from bottom to top. The two come into contact in reverse flow, and the collision between dust particles and water droplets causes them to condense or agglomerate, greatly increasing their weight and settling down by gravity. The captured dust settles by gravity in the storage tank, forming a high solid concentration liquid at the bottom and regularly discharged for further treatment. Part of the clarified liquid can be recycled, and together with a small amount of supplementary clear liquid, it enters the spray tower through a circulating pump from the top nozzle for spray washing. This reduces the consumption of liquid and the amount of secondary sewage treatment. The purified gas after spray washing is discharged from the top of the tower after removing small liquid droplets carried by the gas through a demister.  

3、 Scope of application:

Nitrogen oxides generated in industries such as chemical, electroplating, hardware, aluminum, electrical, pharmaceutical, printing and dyeing; Purification of water-soluble toxic and harmful gases such as hydrogen chloride, hydrogen fluoride, sulfuric acid mist, and chromic acid mist; It can also be applied for deodorization treatment of odorous substances such as ammonia, hydrogen sulfide, formaldehyde, methanol, amines, etc.
