Description

Technical Field

[0001] The utility model relates to the technical field of spray towers, in particular to an integrated two-stage spray tower. Background Technique

[0002] The spray tower, also known as the washing tower and water washing tower, is a gas-liquid generating device. It is mainly used to treat inorganic waste gas. By making the waste gas fully contact with the liquid, the concentration of the waste gas is reduced by using the solubility of the waste gas in water or by means of a chemical reaction, so as to become a clean gas meeting the national emission standards. To ensure the absorption effect, one-stage and two-stage spray absorption towers are often used. After the one-stage spray absorption tower absorbs, the two-stage spray absorption tower ensures that the harmful substances in the gas not fully absorbed in the one-stage spray absorption tower are fully absorbed in the two-stage spray absorption tower. However, the commonly used one-stage and two-stage spray absorption towers have a large floor area, increasing the investment cost, and the absorption effect on harmful substances is not obvious.

[0003] The utility model patent with the publication number of CN217887466U discloses a two-stage multi-layer spray absorption tower. By arranging the first spray area around the second spray area, the floor area of the spray absorption tower can be reduced, saving the investment cost. The gas enters the first spray area from the flue gas inlet. After passing through the packing layer and spray layer of the first spray area, most of the harmful substances in the gas are absorbed. Then the gas enters the second spray area through the connection hole and passes through the spray layer and packing layer of the second spray area, so that the harmful substances not fully absorbed in the first spray area in the gas are fully absorbed in the second spray area, and the absorption effect is more obvious.

[0004] However, the spray tower body of the two-stage multi-layer spray absorption tower is provided with a first spray area and a second spray area, and the first spray area is arranged around the second spray area. In this way, the reduced installation area is only a part less than that of the traditional one, and the installation area is not greatly reduced. Therefore, an integrated two-stage spray tower is proposed to solve the problems raised above. Content of the Utility Model
