Problems solved by technology

[0003] Although the method of landfilling domestic waste does not pollute the atmosphere, it needs to occupy a large amount of land. For each city, it is not advisable to occupy a large amount of land for landfilling domestic waste, and the landfilled domestic waste will pollute the land As well as groundwater resources, it will have a bad impact on future generations; although incineration is feasible, the harmful waste gas produced by kiln incineration will be discharged into the atmosphere without ultra-clean treatment, which will cause smog and toxic and odorous gases, polluting the environment and endanger the health of the people
[0004] The harmful components in the flue gas entangled in waste incineration are complex and diverse, so a single process cannot meet the treatment requirements, and a combination of multiple processes is required

Abstract

The invention relates to the field of environmental protection, and particularly discloses a flue gas purification device used for incineration and capable of realizing efficient adsorption. The fluegas purification device comprises a shell, a heat exchange box, a flue gas inlet pipe and a flue gas outlet, wherein a first transmission shaft is coaxially and rotationally installed on a center shaft of the heat exchange box; a plurality of coaxial check rings are evenly arranged on the outer side of the first transmission shaft, and each check ring is of an annular structure; each check ring isfixedly connected with the first transmission shaft through a plurality of water grooves; a plurality of draining holes are formed in the bottoms of the water grooves; and a spraying cavity, a sand grain filtering cavity and a filter screen filtering cavity are sequentially arranged in the shell from left to right. By arranging the heat exchange box, flue gas makes full contact with cold water; the internal rotating water grooves can bring up the cold water to form a water curtain, and as the flue gas penetrates through the water curtain, heat in the flue gas is absorbed and soot in the fluegas is taken away at the same time; the flue gas sequentially passes through spraying liquid, gravels and a filter screen for filtration and impurity removal; and since multiple purification means areintegrated together, flue gas treatment effect is improved.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a high-efficiency adsorption flue gas purification device for incineration. Background technique [0002] Harmless disposal of domestic waste has become an important task of the environmental protection department; disposal methods of domestic waste include landfill or incineration. [0003] Although the method of landfilling domestic waste does not pollute the atmosphere, it needs to occupy a large amount of land. For each city, it is not advisable to occupy a large amount of land for landfilling domestic waste, and the landfilled domestic waste will pollute the land As well as groundwater resources, it will have a bad impact on future generations; although incineration is feasible, the harmful waste gas produced by kiln incineration will be discharged into the atmosphere without ultra-clean treatment, which will cause smog and toxic and odorous gases, polluting the envir...
