Abstract

The invention discloses an undershoot jet-flow smoke desulphurization device. The undershoot jet-flow smoke desulphurization device comprises a vulcanizing reaction main body, a lime water mixed solution storage tank, a separator, a lime water pump, a pulse valve, two groups of collision jet-flow nozzles, a lime water circulating pump, four undershoot jet-flow nozzles, a bag dust collector, a circulating draught fan, a circulating smoke inlet, a smoke draught fan and a chimney; a lime water solution is crushed into lime water drops in a jet-flow collision manner to be subjected to desulphurization reaction with pollution smoke, unreacted lime water solution is deposited on a frustum-shaped bottom, the unreacted lime water solution is connected with the lime water mixed solution storage tank through the circulating pump, desulphurized smoke is connected with the bag dust collector, and small part of dust-removed smoke slowly enters from the top end of the desulphurization reaction main body so as to slow down the flow rate of the smoke in a desulphurization area. The desulphurization device comprehensively utilizing the jet-flow characteristics has advantages of high desulphurization efficiency, simple process, good stability, low cost and the like.

Description

technical field [0001] The invention relates to a flue gas downdraft jet flow desulfurization device, which belongs to the technical field of atmospheric environment protection. Background technique [0002] Sulfur dioxide is one of the main pollutants in the atmosphere, which is extremely harmful to the human body and the environment. my country is a big country in coal production and coal burning in the world, and the sulfur dioxide emitted by coal burning has a more serious impact. With the release of the "Action Plan for the Prevention and Control of Air Pollution" by the State Council in 2013, the emission and treatment of sulfur dioxide have attracted much attention. [0003] At present, the flue gas desulfurization technology is mainly based on limestone-gypsum wet desulfurization, rotary spray semi-dry desulfurization, activated carbon dry desulfurization, etc. With the development of science and technology, soda sulfide desulfurization method, membrane absorption m...
