DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0022] The incinerator structure of the integrated flue gas treatment device of the present invention is as follows Figure 1 As shown. The incinerator with integrated flue gas treatment device includes: a sewage outlet 1, a sedimentation tank 2, an ash hopper 3, an incineration chamber 4, a smoke collection chamber 5, an emergency exhaust port 6, a spray device 7, a smoke pipe 8, a dry-wet separator 9, a liquid supply pipeline 10 provided with a pump and a valve, and a smoke interface 11 connected to the treatment device outside the furnace. The smoke collection chamber 5 is located below the incineration chamber 4, the ash hopper 3 is located below the incineration chamber 4, and the sedimentation tank 2 is located below the ash hopper 3. In addition to the spray device 7, the smoke treatment device also includes a liquid supply pipeline 10 provided with a pump and a valve, and a smoke pipe 8 connecting the spray device 7 and the sedimentation tank 2. The spray device 7 is arranged in the smoke collection chamber 5.

[0023] When the sacrificial personnel use the incinerator with integrated flue gas treatment device, they can put the sacrifices on the fixed grate through the multiple burning ports arranged around the incineration chamber, and ignite and burn them. The ashes produced by the incineration fall directly into the ash hopper 3 below the grate, and the high-temperature flue gas and smoke generated by the incineration will flow upward into the smoke collecting chamber 5 above the incineration chamber. A temperature measuring device is provided on one side of the smoke collecting chamber 5. When it detects that the temperature in the smoke collecting chamber reaches above 400°C, the motor drives the liquid pump to transport the water in the sedimentation tank 2 through the pipeline 10 to the spray device 7 located in the internal space of the smoke collecting chamber 5. The spray device 7 is provided with a number of high-temperature atomizing nozzles. After the spray water is atomized, it is sprayed obliquely upward into the downward flowing flue gas, thereby increasing the contact area between the water mist and the flue gas, and better cooling and humidifying and filtering the flue gas. After a part of the spray water absorbs a large amount of smoke dust, it flows into the sedimentation tank 2 along the pipeline connecting the smoke collecting chamber 5 and the sedimentation tank 2 together with the flue gas.

[0024] Fiber balls with strong adsorption and filtration functions are provided in the sedimentation tank 2, which can realize the second filtration of smoke gas. In the present invention, the dry-wet separator 9 is arranged at the upper part of the sedimentation tank 2, the purpose of which is to remove the water vapor rich in the smoke after spraying, reduce the operating pressure of the next step processing device, and improve the use efficiency. The interface 11 can be further connected to the processing device outside the incinerator. The external dust removal can adopt a cyclone dust collector or a bag dust collector. In order to further remove odor and fine particles, an electrostatic purifier can be set. An exhaust fan can be set behind the electrostatic purifier, and the smoke is finally discharged into the atmosphere through the chimney.

[0025] An emergency exhaust port 6 is provided on the smoke collecting chamber 5, and a filter screen and a valve are provided inside the pipeline of the emergency exhaust port 6. When the incinerator and internal components temporarily fail, the valve on the emergency exhaust port 6 can be opened, and the incineration smoke can be discharged through the emergency exhaust port 6.

[0026] A sewage outlet 1 is provided at the bottom of the sedimentation tank 2 to discharge the sediment accumulated during long-term use. During long-term use, the water in the sedimentation tank 2 needs to be replaced regularly to meet the needs of dust removal and filtration. For this purpose, a water valve and a water pump are provided on the outside of the sedimentation tank 2 to replace the live water according to the use conditions. A liquid level gauge is provided inside the sedimentation tank to monitor the water level of the sedimentation tank to ensure that the needs of cooling, spraying dust removal and filtration can be met.

[0027] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
