SPECIFIC EMBODIMENTS

[0011] The following will further elaborate on the specific embodiments of the present invention in conjunction with the drawings.

[0012] The present invention discloses a sewer gas burner, including a stove top panel 1 and a stove bottom plate. A closed flame pot ring 3 is installed on the stove top panel. In the center of the closed flame pot ring 3, an inner circle 2 of the return air channel fixed on the stove bottom plate is installed. In the center of the inner circle of the return air channel, a gas combustion device connected to the gas delivery pipe 9 is installed. The outer wall of the inner circle 2 of the return air channel is connected to the air outlet of the fan through the first intake pipe 15, and the gas combustion device is connected to the switch control of the fan; The air inlet of the fan is connected to a desulfurization device 14, and the desulfurization device is also connected to a second intake pipe 20. The outer wall of the closed flame pot ring is also connected to an exhaust pipe.

[0013] Installation holes for the closed flame pot ring 3 and the gas power ignition valve 8 are provided in the center of the stove top panel 1. Installation holes and through holes for the exhaust pipe 14, the first intake pipe 15, and the gas fire bucket pipe 10 are provided on the ring walls of the closed flame pot ring 3 and the inner circle 2 of the return air channel. The center of the stove top panel 1 is fixed on the stove bottom plate 16.

[0014] The combustion fire bucket cover 4 is provided with combustion fire holes 5 for combustion and is installed on the surface of the combustion fire bucket 11. The bottom of the combustion fire bucket 11 is provided with a fire bucket ventilation hole 12 to facilitate the entry of air for combustion assistance.

[0015] The side wall of the combustion fire bucket positioning disc 6 is also provided with a positioning disc ventilation hole 7 to further facilitate air circulation and assist combustion at the top layer of the combustion fire bucket. The combustion fire bucket 11 is installed in the center of the combustion fire bucket positioning disc 6 and is installed together with the combustion fire bucket positioning disc 6 at the upper half part within the inner circle 2 of the air return channel. The pot body 27 is placed on the closed flame pot ring 3 and can be used for cooking, stir-frying, and boiling water, so that the flames generated during the combustion of the combustion fire bucket cover 4 do not spread outwards, improving the thermal energy utilization rate.

[0016] The gas power ignition valve 8 is connected to the gas delivery pipe 9 and is connected to the combustion fire bucket 11 through the gas fire bucket pipeline 10. The gas power ignition valve 8 is installed on the stove top panel 1 and serves to ignite the stove fire and control the size of the gas flow rate.

[0017] The stove wall panel 17 is installed below the stove top panel 1 and serves to support and enclose the periphery of the stove top panel 1. The stove wall panel 17 is provided with installation through holes for the exhaust pipeline 14 and the second intake pipeline 20.

[0018] The desulfurization device 19 is installed below the stove top panel 1 and is closely attached to the stove wall panel 17. The desulfurization device is a device that can adsorb sulfur-containing gas components, such as a metal grid filled with quicklime, as Figure 1 shown. The desulfurization device 19 is a rectangular box-shaped device with two ventilation hole interfaces. During operation, it is filled with granular desulfurizing agent such as quicklime. The upper ventilation hole interface is connected to the suction pipe interface of the fan 18 and is welded to the fan as a whole. The lower ventilation hole interface is connected to the second intake pipeline 20.

[0019] As Figure 1 and Figure 2 shown, in the use state, one end of the second intake pipeline 20 is connected and installed on the floor drain pipe 22, and the other end is installed on the desulfurization device 19 through the through hole of the stove wall panel 17. One end of the first intake pipeline 15 is installed on the fan 18, and the other end passes through the air return channel 13 and the inner circle 2 of the air return channel through the through hole on the wall of the closed flame pot ring 3 and enters the inner circle 2 of the air return channel. Through the above connection method, the gas containing microorganisms and toxic and harmful components in the sewer can be introduced into the combustion fire bucket 11 to be mixed and burned with the conventional gas.

[0020] A return air channel 13 is formed between the closed flame pot ring 3 and the inner circle 2 of the air return channel to surround the inner circle 2 of the air return channel. The return air channel 13 is connected to the external sewer pipeline through the exhaust pipeline 14 to discharge the exhausted gas after combustion.

[0021] One end of the exhaust pipe 14 is connected to the floor exhaust pipe 21, and the other end is connected to the enclosed flame cooker ring 3, so as to discharge the burned dust and waste gas through the floor exhaust pipe 21. The floor exhaust pipe 21 is a flue gas pipe that is compulsorily installed in existing residential buildings for discharging kitchen and water heater waste gas.

[0022] The floor sewer 22 is mainly used for discharging wastewater, waste and food waste on the floor. It is connected to the outdoor main sewer purification pool 23 and the outdoor ground sewer 24. The present invention seals and stores the toxic and harmful gases such as hydrogen sulfide H2S, methane CH4, ammonia NH3, carbon monoxide CO, non-methane total hydrocarbons NMHC and other pathogenic parent bodies generated by the outdoor main sewer, the garbage purification pool 23, the outdoor ground sewer 24 and the floor sewer 22, and then returns them to the combustion hopper 11 through the floor sewer 22 to be mixed and burned with other combustible gases sent by the gas cooker pipeline 10. The sewer odor and microbial pathogenic parent bodies are exterminated during combustion, effectively controlling the carbon emissions of the sewer and the diffusion and transmission of microbial pathogenic parent bodies through the sewer.

[0023] The sewer closing device 25 is installed on the wellhead of the outdoor ground sewer 24, lower than the outdoor ground 26, facilitating the inflow of surface water and debris into the sewer. Without interfering with the original wellhead function, it seals and stores the toxic and harmful substances such as hydrogen sulfide H2S, methane CH4, ammonia NH3, carbon monoxide CO, non-methane total hydrocarbons NMHC and other pathogenic parent bodies generated in the sewer, as well as other pathogenic parent bodies and carbides, controlling the spread and facilitating treatment and utilization.

[0024] The process of the sewer gas burner of the present invention during operation is as follows: Start the gas power ignition valve 8. The gas power ignition valve 8 is connected to the switch control of the blower 18 through an electronic control device. When the ignition valve is closed by the knob switch and the ignition circuit starts to control, an enabling signal is simultaneously sent to make the blower 18 work synchronously. The gas generated in the sewer is sent into the inner ring 3 of the return air duct through the floor sewer pipe 22, the second intake pipe 20, the desulfurization device 14, the blower 18 and the first intake pipe 15, then enters the combustion hopper 11, is fully mixed with the gas sent by the gas pipeline, and then sprays out from the combustion holes of the combustion hopper cover 6 for combustion.

[0025] By using the sewer gas burner of the present invention, the combustible gas in the floor and ground sewers can be utilized to generate heat energy during combustion, and the toxic and harmful gases in them can be removed simultaneously during the combustion process, effectively controlling the carbon emissions of the sewer and the spread of microorganisms.

If the preferred implementation manners in each preferred embodiment are not obviously self-contradictory or premised on a certain preferred implementation manner, each preferred implementation manner can be arbitrarily superimposed and combined for use. The embodiments and the specific parameters in the embodiments are only for clearly expressing the inventor's invention verification process, and are not used to limit the patent protection scope of the present invention.
