[0025] Please refer to Figures 1-4 , an embodiment provided by the present invention: a multi-chamber combustion type waste gas treatment furnace body structure, including a furnace body 1, a combustion cavity is arranged inside the furnace body 1, an upper grate 3 is fixedly installed inside the combustion cavity, a lower grate 4 is fixedly installed below the upper grate 3, the aperture of the through hole on the upper grate 3 is larger than the aperture of the lower grate 4, and the upper grate 3 and the lower grate 4 form the internal structure design of a double grate, so as to form a double-layer grate combustion design above the upper grate 3 and the lower grate 4;

[0026] The outer circle of the lower grate 4 and inside the furnace body 1 is wrapped with a secondary combustion chamber 7. The outer circle of the upper grate 3 and inside the furnace body 1 is wrapped with a tertiary combustion chamber 9. The inside of the secondary combustion chamber 7 is filled with heat storage honeycomb steel balls 8, and the heat storage honeycomb steel balls 8 are of the specification of Φ100mm heat storage honeycomb steel balls 8. The porous groove heat storage ceramic balls 10 are of the specification of Φ35mm heat storage ceramic balls. The inside of the tertiary combustion chamber 9 is filled with porous groove heat storage ceramic balls 10, and the porous groove heat storage ceramic balls 10 are of the specification of Φ35mm heat storage ceramic balls;

[0027] When the heat storage honeycomb steel balls 8 and the porous groove heat storage ceramic balls 10 are working, they can store heat up to 900 °C inside;

[0028] Among them, in order to facilitate the smooth entry of flue gas from the secondary combustion chamber 7 into the tertiary combustion chamber 9, the secondary combustion chamber 7 and the tertiary combustion chamber 9 are designed with an intercommunicating structure;

[0029] Through the combined use of the internal main combustion chamber and the structures of the secondary combustion chamber 7 and the tertiary combustion chamber 9, the flue gas containing waste can be combusted multiple times, with the pyrolysis effect of multi-combustion of garbage, effectively improving the pyrolysis quality and the emission quality of flue gas, reducing air pollution, having a good environmental protection use effect, and being suitable for purification use in garbage incineration;

[0030] Moreover, an exhaust port 11 is fixedly installed on the outside of one side of the tertiary combustion chamber 9. Through the provided exhaust port 11, an external pipeline can be connected, so as to facilitate the removal of flue gas from the furnace body of the present invention for the next process;

[0031] The cavity above the upper grate 3 forms an upper combustion chamber 2, and the cavity above the lower grate 4 forms a lower combustion chamber 12. One outer wall of the upper combustion chamber 2 is fixedly connected with a smoking pipe 5. The tail end of the smoking pipe 5 is fixedly connected with the input port of a smoking pump 6, and the output port of the smoking pump 6 communicates with the secondary combustion chamber 7 through a pipeline;

[0032] The flue gas pyrolyzed and combusted in the upper combustion chamber 2 and the lower combustion chamber 12 can be transported to the secondary combustion chamber 7 at the bottom through the smoking pipe 5 and the smoking pump 6, so as to effectively transport the flue gas from the top to the bottom, completing the transport characteristic of reverse suction, in order to fully purify and combust the flue gas subsequently.

[0033] In this embodiment, in order to facilitate the pushing and feeding of garbage, a hydraulic pushing device 13 is fixedly installed on the back of the upper combustion chamber 2 and outside the furnace body 1. The hydraulic pushing device 13 is composed of a hydraulic driving cylinder and a pushing plate. By driving the pushing plate to slowly advance through the provided hydraulic driving cylinder, the slow pushing and feeding of garbage can be completed.

[0034] In this embodiment, in order to improve the efficiency during garbage pyrolysis, a magnetizer 14 is fixedly installed on one outer wall of the furnace body 1. The output end of the magnetizer 14 is fixedly connected with a magnetization pipeline 15, and the magnetization pipeline 15 is laid inside the secondary combustion chamber 7 at the bottom end of the furnace body 1;

[0035] With this structural design, the air magnetized by the magnetizer 14 enters the interior of the secondary combustion chamber 7 through the magnetization pipeline 15. The pressurized air discharged upward can effectively agitate the flue gas and garbage inside, improving the combustion efficiency. At the same time, the magnetized air will generate wave impacts, forming a magnetic fluid to bombard the large molecular chains of organic substances, accelerating the decomposition of garbage and improving the quality of pyrolysis gasification.

[0036] In this embodiment, in order to facilitate the injection of garbage before pyrolysis, a feed inlet 16 is fixedly installed on the outer wall of the top end of the furnace body 1. The garbage can be injected through the provided feed inlet 16.

[0037] Working principle:

[0038] Before use, a pipeline can be connected to the outside of the exhaust port 11, and the tail end of the external pipeline can be connected to the air inlet of the next process equipment to ensure normal flue gas purification treatment;

[0039] When the present invention is actually used, the garbage to be pyrolyzed can be injected through the provided feed inlet 16, and the injected garbage enters the main combustion chamber inside the furnace body for combustion and decomposition;

[0040] During the combustion and decomposition process in the main combustion chamber, a part of the unburned flue gas is generated. The flue gas is transported from the top to the interior of the secondary combustion chamber 7 at the tail through the smoke pipe 5 and the smoke pump 6. The combustion flame layer inside the secondary combustion chamber 7 performs secondary heating and combustion on the substances in the flue gas that are not fully burned. At the same time, by arranging a heat storage honeycomb steel wire ball 8 inside the secondary combustion chamber, when the flue gas containing residual harmful impurities passes through the 900°C steel wire ball, secondary combustion and purification can be carried out to improve the flue gas treatment effect;

[0041] The flue gas treated by the secondary combustion chamber 7 enters the tertiary combustion chamber 9. Porous groove heat storage ceramic balls are arranged inside the tertiary combustion chamber 9. When the harmful substances containing unburned residues pass through the 900°C porous groove heat storage ceramic balls, combustion and purification are carried out again, and finally, it is discharged through the exhaust port 11 and enters the next treatment equipment;

[0042] At the same time, when the pyrolysis is carried out in the furnace body 1, the magnetizer 14 works synchronously. The air magnetized by the magnetizer 14 enters the interior of the secondary combustion chamber 7 through the magnetization pipeline 15. The pressurized air discharged upward can effectively agitate the flue gas and garbage inside, improving the combustion efficiency. At the same time, the magnetized air will generate wave impacts, forming a magnetic fluid to bombard the large molecular chains of organic substances, accelerating the decomposition of garbage and improving the quality of pyrolysis gasification.

[0043] In summary, for the multi-chamber combustion type waste gas treatment furnace body structure of the present invention, during actual use, through the inverted air extraction type structure design, the waste gas at the top can be inverted and extracted to the secondary combustion chamber at the bottom of the furnace body for secondary and tertiary combustion operations, improving the combustion purification quality of the waste gas;

[0044] Meanwhile, through the combined use of the internal main combustion chamber, secondary combustion chamber and tertiary combustion chamber, the flue gas containing waste can be combusted multiple times, having the pyrolysis effect of multi-combustion of waste gas, enabling the waste gas containing impurities to be combusted multiple times, effectively improving the pyrolysis quality and the flue gas emission quality. The harmful substances in the flue gas have been completely eliminated through multiple combustions, which can effectively reduce air pollution and has a good environmental protection effect in use, and is suitable for purification in waste incineration;

[0045] Moreover, the present invention is equipped with a magnetizer. The air magnetized by the magnetizer enters the secondary combustion chamber through the magnetized pipeline. The pressurized air discharged upward can effectively stir the flue gas, waste and air inside, improving the combustion efficiency. At the same time, the magnetized air will generate wave impacts, forming a magnetic fluid to bombard the large molecular chains of organic substances, accelerating the decomposition of waste and improving the pyrolysis gasification quality.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
