Spray tower, also known as washing tower and water washing tower, is a gas-liquid generating device. The waste gas is in full contact with the liquid, and its concentration is reduced by chemical reaction or chemical reaction, so as to become a clean gas conforming to the national emission standard. It is mainly used to treat inorganic waste gas, such as sulfuric acid mist, hydrogen chloride gas, oxides of different valence states of nitrogen, namely NOx, dust waste gas, etc.
The washing tower has low noise, stable operation, simple and convenient operation; Water washing waste gas treatment system, cheap price and simple treatment method; Gaseous, liquid and solid pollution sources can be treated; Low system pressure loss, suitable for large air volume; The multi-stage packing layer design can be adopted to deal with mixed pollution sources. It can treat acid and alkaline waste gas economically and effectively, and the removal rate can be as high as 99%.
Features:
(1) it has a wide range of applications. The industrial waste gas spray tower can achieve satisfactory results for organic waste gas, sulfuric acid, nitric acid, hydrochloric acid, and other tail gases, as well as sour gases such as sulfur oxide (SOx), nitrogen oxide (NOx), carbon oxide (co, CO2), (HCN) emitted in the production process of industrial departments.
(2) high waste gas purification efficiency: the acid (alkali) mist waste gas purification tower adopts two-stage or three-stage reverse spraying, with large specific surface area of packing. The gas ratio determined by experimental research ensures stable performance, and the purification efficiency of various concentrations of acid (or alkali) waste gas can reach more than 80%.
(3) low resistance of waste gas treatment tower: on the basis of ensuring sufficient gas-liquid contact area, the industrial waste gas spray tower selects packing varieties and structural forms with aerodynamic characteristics to reduce the resistance of the equipment, which is extremely beneficial to the allocation of corrosion-resistant low-pressure fans.
(4) the waste gas treatment tower occupies a small area: the industrial waste gas purification and treatment tower is made of PP, FRP and other materials. The tower body, absorption liquid tank, circulation pump and absorption liquid pipeline system are combined into a complete set of industrial waste gas treatment equipment. The structure is compact, which is convenient for on-site installation and operation management, and the floor area is small.
Generally, spray tower (absorption tower, purification tower) is equipped with activated carbon box to form multi-stage and multi equipment treatment, so that industrial waste gas can reach a good treatment scheme.
Application range:
Chemical industry, light industry, printing and dyeing, medicine, steel, machinery, electronics, instruments, electroplating and other industrial departments
