Description

Technical Field

[0001] The utility model relates to the field of water washing towers, in particular to a waste gas purification water washing tower. Background Art

[0002] The waste gas purification water washing tower, also known as the spray tower, is a gas purification treatment equipment. Its working principle is to remove impurities in the gas by reacting with a solvent, so as to achieve the purpose of "cleaning" the waste gas. This equipment is usually used for industrial waste gas treatment and ventilation waste gas plants. In some early coal chemical industries, spray towers are also used for dust removal and dehumidification. At present, in order to meet the initial stage of pollution gas treatment, spray towers are widely used in the treatment of polluted waste gas and organic waste gas, and the effect is better as the early stage of comprehensive waste gas treatment.

[0003] During the use of the waste gas purification water washing tower, the waste gas is passed from one side of the purification tower to the inside of the purification tower. At this time, the cleaning liquid is sprayed out through the spray device, and the cleaning liquid contacts the waste gas, thereby achieving the purpose of purifying the waste gas. In this process, when the waste gas is passed into the purification tower, it is generally passed from one side of the purification tower. After the waste gas enters the interior of the purification tower through the pipeline, the waste gas overflows from the pipeline and gradually diffuses outward. Since the waste gas contains heat, the waste gas moves upward and diffuses to the surrounding area. However, the diffusion effect is not good through the diffusion of the gas itself. The flue gas concentration at the center of the inner cavity of the purification tower is higher than the flue gas concentration at the edge of the inner cavity of the purification tower. To a certain extent, the purification effect of the waste gas is reduced.

[0004] Therefore, it is necessary to provide a new waste gas purification water washing tower to solve the above technical problems. Utility Model Content
