Circulating spray absorption tower for flue gas purification treatment

Abstract

The invention relates to a circulating spray absorption tower for flue gas purification treatment. The absorption tower comprises a cylindrical liquid storage tower body and a cylindrical spray towerbody connected with the top end of the liquid storage tower body; a cleaning and scraping mechanism is arranged on the liquid storage tower body; two spraying pipeline assemblies capable of horizontally rotating are vertically arranged in the spray tower body; and a rotation driving mechanism used for driving the two spraying pipeline assemblies to rotate is arranged on the outer side wall of thespray tower body. According to the absorption tower provided by the invention, a spraying medium liquid can be uniformly and widely distributed in the spraying space, so that flue gas flowing upwardscan be in contact exchange with the spraying medium liquid at equal probability, and the spraying absorption effect can be improved and guaranteed; in addition, solid precipitates can be continuouslyscraped off, and formation and accumulation of a precipitation layer are avoided.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, and specifically proposes a flue gas purification treatment circulation spray absorption tower. Background technique [0002] In the field of industrial production, in order to meet the requirements of the corresponding national environmental protection standards and maintain the air environment, it is generally necessary to purify the waste gas generated in the industrial production process. For the waste gas mixed with a lot of non-toxic smoke and dust, the waste gas is mainly treated by dust removal. Purification treatment, for the treatment of toxic and harmful waste gas, in addition to the general dust removal and purification treatment, it is also necessary to purify the harmful components of the waste gas to meet the emission standards of the waste gas. [0003] In the prior art, purification technologies such as foam towers, spray towers, and packed towers can b...

Problems solved by technology

[0004] 1) The spray pipeline structure in the existing spray tower is basically a fixed structure. In the actual spray process, there is a problem of uneven distribution of the spray medium liquid in the spray space, which makes the upward facing The probability of contact between the flowing exhaust gas and the spray medium liquid is inconsistent, which in turn causes the effect of waste gas treatment to be unsatisfactory. Increase the height of the spray tower (the method of increasing the height is actually to extend the gas flow path) or increase the amount of spray medium liquid In order to ensure the effect of exhaust gas treatment, it will increase the equipment input cost and operating cost, and will also increase the burden of equipment operation;

[0005] 2) For different exhaust gas components, the corresponding spray medium liquid will be proportioned, but some components of the spray medium liquid will form solid precipitation after contacting and reacting with the exhaust gas, and will be deposited in the spray tower with the long-term working process. The formation of sediment accumulation, resulting in the reduction of the working space and the inconvenience of later cleaning
