The waste incineration can generate smoke and release energy at the same time. Due to the complexity of the components of the waste, the flue gas generated by the incineration of the waste contains many harmful substances (such as particulate matters, acid gases, metals and the like), and the substances have different degrees of harm to the environment according to the quantity and the properties of the substances. Therefore, the smoke generated by the incineration of the garbage is a main source of pollution generated in the incineration treatment process. In view of the environmental and human health hazards posed by these materials, incineration flue gases must be cleaned to meet emission standards before being discharged into the atmosphere. Since the 90 s of the 20 th century, economically developed countries attach more and more importance to pollution control of incineration flue gas, emission standards are stricter and more high one-time engineering investment and operating cost for flue gas purification. The requirements of flue gas treatment and flue gas emission also become important factors influencing the economy and the environmental impact of waste incineration treatment.
The importance of the process of removing nitrogen oxides from combustion fumes to prevent environmental pollution has been pointed out as a worldwide problem. The mainstream process in the world comprises the following steps: SCR and SNCR. These two processes are not very different except that the reaction temperature is lower than SNCR due to the use of catalyst for SCR, but the SCR investment is at least several times, even more than 10 times, the SNCR investment if both from the point of view of construction costs and operating costs.
In the prior art, when denitration is performed on garbage combustion flue gas, the denitration is generally performed by introducing the denitration into an alkaline solution to convert nitrogen oxides in the flue gas into nitrate or nitrite, but in the actual operation process, because nitric oxide in the nitrogen oxides can be independently reacted with the alkaline solution, if the nitric oxide is directly discharged into the alkaline solution, part of the nitric oxide is easy to escape due to too high content of the nitric oxide, so that the atmosphere is polluted.

The denitration device based on garbage combustion flue gas as claimed in claim 2, characterized in that: the inner wall of the water delivery conduit (10) is fixedly connected with a blocking-proof filter screen (1001), the blocking-proof filter screen (1001) is positioned on the upper side of the one-way valve, and the aperture of the meshes of the blocking-proof filter screen (1001) is smaller than the particle size of the calcium peroxide powder.
8. The denitration device based on garbage combustion flue gas as claimed in claim 2, characterized in that: the magnetic isolation balloon is characterized in that a plurality of uniformly distributed magnetic isolation powder is embedded in the outer wrapping balloon (11), the magnetic isolation powder is made of iron-nickel alloy, and the nickel content of the magnetic isolation powder is 80%.
9. The use method of the denitration device based on garbage combustion flue gas as claimed in any one of claims 1 to 8, characterized in that: the method comprises the following steps:
s1, promoting the calcium peroxide powder in the dynamic bearing ball frame (5) to decompose through the heat in the smoke, generating a large amount of oxygen, ejecting the oxygen from the release bent guide pipe (7) after the oxygen pushes open the rubber sealing sheet (8), and fully reacting with the nitric oxide in the smoke;
s2, the sealing air bag ring (6) can be rapidly expanded by means of temperature rise, so that the space between the movable bearing ball frame (5) and the sealing air bag ring (6) is sealed, and the efficiency of downward movement of the movable bearing ball frame (5) can be improved by means of air pressure increase of smoke;
s3, the built-in traction ball (9) is made to expand and is made to contact with a magnetic shielding state, and the movable bearing ball frame (5) is made to move downwards to an interface contacting with a sodium hydroxide solution by virtue of the repulsion action of the fixed magnet ball (3) on the built-in traction ball (9), so that calcium peroxide powder in the movable bearing ball frame (5) is broken up, and the collection and decomposition efficiency is improved.
