Example

[0017] See attached Figure 1 As shown, a biogas combustion device for a sewage anaerobic system includes a water seal tank 2, a filter 4 and a biogas torch 14, wherein the inlet of the water seal tank 2 is connected to a biogas manual main valve 1 through a pipeline, a liquid level gauge 3 is arranged in the water seal tank 2, the water seal tank 2 is connected to the filter 4 through a pipeline, a manual butterfly valve 5 is arranged on the output pipeline of the filter 4, and one side of the manual butterfly valve 5 is connected to a biogas pressure gauge 6, and the output end of the biogas pressure gauge 6 is divided into two pipelines;

[0018] One of the paths passes through electromagnetic pressure switch 1 7, electromagnetic pressure switch 2 8, and electromagnetic pressure switch 3 9, and passes through electric butterfly valve 10 and flame arrester 11 on the pipeline to enter nozzle 12 inside biogas torch 14, and a combustion head 13 is provided above the nozzle 12;

[0019] The other path passes through the ignition manual valve 17 , and is connected to the ignition flame arrester 20 via the ignition solenoid valve 18 or the ignition bypass manual valve 19 . The ignition flame arrester 20 is connected to a permanent lamp 21 , and the permanent lamp 21 is connected to an ignition rod 22 .

[0020] Preferably, a flame monitor 23 and a temperature sensor 24 are provided in the biogas torch 14 .

[0021] Preferably, a heat insulating layer 15 is provided inside the biogas torch 14 , and a rainproof cover 16 is provided on the top of the biogas torch 14 .

[0022] Preferably, the filter 4 is provided with a filter drain valve 25 .

[0023] Preferably, the water seal tank 2 is provided with a water seal tank filling valve 26 and a water seal tank drain valve 27 .

[0024] Working principle: Biogas comes from the anaerobic tank, passes through the biogas manual main valve 1 and enters the water seal tank 2. The biogas passes through the inlet pipe of the water seal tank 2 and enters below the water surface in the water seal tank. After reaching a certain pressure, it breaks through the water seal and enters the flare barrel 14 for release, which plays a role in stabilizing pressure. At the same time, the function of the water seal tank 2 is to prevent the occurrence of flashback. If flashback occurs, the flame enters the water seal tank 2 through the flare gas outlet, and because the inlet pipe is below the water surface, the flame is prevented from continuing to spread.

[0025] The water seal tank 2 is provided with a liquid level gauge 3, a water seal tank water filling valve 26 and a water seal tank drain valve 27. The liquid level gauge 3 reflects the water level of the water seal tank 2. If the water level is high, the water is discharged in time through the water seal tank drain valve 27. In addition, when the water seal tank 2 is used, water can be filled into the water seal tank 2 through the water seal tank water filling valve 26, and the water seal tank 2 can also be cleaned through the water seal tank water filling valve 26 and the water seal tank drain valve 27.

[0026] The biogas passing through the water seal tank 2 enters the filter 4 through the pipeline, and the filtered biogas passes through the manual butterfly valve 5 and then passes through the biogas pressure gauge 6 to be divided into two paths;

[0027] One of the paths passes through electromagnetic pressure switch 1 7, electromagnetic pressure switch 2 8, and electromagnetic pressure switch 3 9, and passes through electric butterfly valve 10 and flame arrester 11 on the pipeline to enter nozzle 12 inside biogas torch 14, and finally sprays out through combustion head 13. Electromagnetic pressure switch 1 7, electromagnetic pressure switch 2 8, and electromagnetic pressure switch 3 9 are used to automatically adjust the biogas size according to low, medium, and high biogas pressures;

[0028] The other path passes through the ignition manual valve 17, and is connected to the ignition flame arrester 20 through the ignition solenoid valve 18 or the ignition bypass manual valve 19. At this time, the biogas sprayed from the pilot lamp 23 is ignited through the ignition rod 24, and the flame of the ignited pilot lamp 23 quickly ignites the biogas sprayed from the combustion head 15, so that the biogas torch 16 is in a burning state;

[0029] The combustion condition can be uploaded to the control screen for display via the flame monitor 25 and the temperature sensor 26 to display the ignition condition and normal combustion temperature;

[0030] The interior of the biogas torch is lined with a heat insulation layer 17 to protect the inner wall and prevent the outer wall from being burned by high temperature.

[0031] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model; therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description. Therefore, it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model, and any figure marks in the claims should not be regarded as limiting the claims involved.
