[0004] The above-mentioned new type of environmental protection treatment system for waste incineration flue gas is to turn on the thermostat to maintain a suitable temperature after the slag ash enters the degradation bin, and use the biodegradation method to remove heavy metal pollutants in the slag, so that the ash with reduced toxicity is put into the solidification bin for solidification, and then released into the mold for shaping. However, the dust released by the combustion is processed, and the odor generated by the combustion of garbage and the sulfur that is easily carried by the flue gas are not easy to be removed. Secondly, the discharged sulfur needs to be processed before it can be released; for this reason, we provide an environmental protection dust removal device for waste incineration. By setting an annular pipe, the flue gas to be discharged is sprayed, and the sprayed gypsum desulfurizer can react with the sulfur in the flue gas to form lime slurry, which sinks to the bottom of the purification tank for subsequent treatment. Secondly, the garbage has a strong odor. After burning, it needs to be filtered to avoid affecting the external environment. After spraying, the gas will carry moisture, and the moisture capture plate can filter out excess moisture, and the activated carbon adsorption plate can remove irritating odors to ensure that the discharged gas meets the emission standards, thereby effectively compensating for the above-mentioned problems.
