[0036] The working principle of the embodiment is as follows:

[0037] When the flue gas needs to be discharged, the flue gas first flows out from the inside of the cover body 9 through the gas inlet pipe 15, and then the spray pipe 8 and the spray head in the cover body 9 will spray the spray liquid under the supply of the liquid supply pipe 7, so as to preliminarily remove part of the toxic and harmful fixed impurity particles in the flue gas. Subsequently, the flue gas purified by the spray liquid will flow out from below the cover body 9 and flow to the demisting ring plate 4 from the gap between the outer wall of the cover body 9 and the inner wall of the tank body 1, and the spray liquid carrying solid impurity particles will flow out from the liquid outlet pipe 16 and then return to the liquid supply pipe 7 after being filtered in a cycle. Then, the demisting ring plate 4 removes the water mist in the flue gas that passes through, so as to ensure that the flue gas can dry and penetrate the adsorption ring plate 5 and the filter ring plate 6. Finally, the flue gas discharged from the gas outlet of the tank body 1 will be removed by the adsorption ring plate 5 and the filter ring plate 6 in the forms of adsorption and separation, respectively, to remove the toxic and harmful gas and small particles in the flue gas, so as to sufficiently purify the flue gas and make the flue gas quickly reach the discharge standard.

[0038] When the internal components of the tank body 1 need to be cleaned and maintained, first, the screws fixedly connecting the tank body 1 and the tank cover 2 are unscrewed, then the hooks of the crane are hung on the lifting rings 22 on the top of the tank cover 2, and the crane is operated to lift the tank cover 2 from the top opening of the tank body 1. Since the tank cover 2 is connected to the filter ring plate 6, the adsorption ring plate 5, the demisting ring plate 4, the cover body 9 and other structures through the support rod 3, the important components for purifying flue gas will be away from the inside of the tank body 1 during the lifting of the tank cover 2, so as to facilitate the staff to quickly clean and maintain most of the components in the tank body 1. At the same time, the part of the liquid supply pipe 7 above the spray pipe 8 will gradually be positioned in the hole 31 and separated out during the lifting of the tank body 1. Finally, the cleaning liquid is delivered into the liquid supply pipe 7, which will be sprayed out through each water outlet 71 on the liquid supply pipe 7 and sprayed on the inner wall of the tank body 1 in all places, so as to facilitate the staff to manually clean the inner wall of the tank body 1.

[0039] The flue gas purification structure is simple, effective, low in failure rate, and simple and convenient to disassemble the parts in the tank, so that the cost required for manual cleaning and maintenance of the flue gas removal device is low, and the device is relatively safe and stable in long-term use.
