[0024] In this embodiment, when the staff needs to use the device to treat the flue gas generated by the incinerator, the alkali substances such as sodium hydroxide, calcium hydroxide and sodium carbonate can be placed on the partition plate 111 of the gas permeable box 110 in advance, which can react with the acidic substances in the flue gas to generate harmless or low-hazard substances such as salt and water, thereby achieving the purpose of deacidification. Therefore, after the cover plate 19 is opened, the gas permeable box 110 containing the alkali substances is placed in the purification box 14, and the flue gas in the incinerator body 12 and the pipeline 13 is extracted into the purification box 14 by starting the air extractor 113 to generate strong suction. The dust and impurities in the flue gas are filtered by the filter screen 16.

At the same time, the protective fence 22 can also prevent external objects from entering the interior of the equipment, thereby avoiding damage to the equipment.

[0027] The utility model provides a kind of incinerator flue gas deacidification device, specific working principle as follows:

[0028] When the staff needs to use the device to carry out deacidification treatment on the flue gas generated by the incinerator, the alkaline substances such as sodium hydroxide, calcium hydroxide and sodium carbonate can be placed on the partition plate 111 of the air tank 110 in advance. In order to put the air tank 110 containing alkaline substances into the purification tank 14, the staff needs to open the cover plate 19, and then generate strong suction by starting the air extractor 113 to extract the flue gas in the incinerator body 12 and the pipeline 13 into the purification tank 14. In the purification tank 14, the flue gas will pass through a filter screen 16, which is used to filter the dust and impurities in the flue gas. The flue gas filtered by the filter screen 16 will react with the alkaline substances in the air tank 110, which makes the treated flue gas cleaner and more environmentally friendly. Because the alkaline substances can neutralize the acidic components in the flue gas, reduce its harm to the environment and human health. Finally, the purified flue gas can be discharged through the air outlet 32, and the flue gas treatment process is completed, achieving the expected purification effect. However, as time goes by, a large amount of dust and impurities may accumulate on the filter screen 16, affecting its filtering effect. Therefore, when the filter screen 16 needs to be cleaned, the staff can pull the pull plate 15 upwards, which can take out the filter screen 16 from the purification tank 14 for cleaning and maintenance. After cleaning, the filter screen 16 is reinstalled into the purification tank 14 to continue the filtering and purification work of the flue gas.
