How to check if the biogas hose is leaking during use

Turn on the switch of the gas pipeline, then add water to the pool to the movable cover, exhaust the air in the space of the air box in the pool, and then turn off the switch. Take out the water from the pool, so that the water level drops to about 600mm below the cover, after 24 hours, if there is no abnormal change (that is, the water level remains unchanged, the movable cover does not leak, etc.), then light a candle or oil lamp, aim the gas pipe nozzle at the flame, turn on the switch, if the flame is sucked in by the nozzle at this time, indicating that the air box part is ***, no air leakage; If the flame does not rise as usual, it indicates that the gas box is leaking.

After a period of time after the biogas digester is charged (5 10 days in summer, and about 20 days after the pool temperature is above 10 in winter), if there is still no gas production, the gas box may leak, and the gas pipeline can be aimed at the flame (note: the gas pipeline is 10m away from the biogas tank, and it is strictly forbidden to ignite at the mouth of the gas pipe, so as not to temper into the pool and cause the pool), turn on the switch. If no air is ejected and the flame does not move, it proves that the gas box (or conveyor) is leaking; If there is gas spewing out and not combustible, it is too much miscellaneous gas, exclude it several times and try again; If it can be ignited, it is less gas production, which is a normal phenomenon in the process of having nothing and going from less to more.

When the biogas pipeline leaks, the following two things should be done in time:

1) Close the total opening of the outlet pipe of the biogas digester immediately to prevent further air leakage.

2) It is strictly forbidden to generate ignition sources and electric sparks in the place where the pipeline leaks, until the biogas is diluted and dissipated; If there is an air leak in the indoor pipeline, in addition to strictly prohibiting the fire source and electric sparks, the doors and windows should be opened immediately for ventilation to dissipate the biogas. Then the air leakage part should be overhauled, and the pressure test should be carried out after repair to ensure that there is no longer air leakage before normal use.

When the biogas pipeline leaks, the following two things should be done in time:

Close the main valve at the outlet pipe of the digester immediately to prevent further air leakage.

In the place where the pipeline leaks, it is strictly forbidden to generate ignition and electric sparks until the biogas is exhausted. If there is a leak in the indoor pipeline, in addition to prohibiting the fire source and electric sparks, the doors and windows should be opened immediately to dissipate the biogas. After the above two steps are done, the air leakage part should be overhauled, and after repair, it should be ensured that there is no more air leakage before normal use.

Cao Qunfang) What is the rural clean energy utilization rate? The rural clean energy utilization penetration rate refers to the percentage of clean energy consumption in administrative villages to their total energy consumption, and the percentage of rural households that use clean energy as the main fuel in the actual operation is replaced by the percentage of all rural households. The so-called clean energy refers to the primary energy and secondary energy that produce no or very few pollutants after consumption.

Clean energy includes solar, wind, hydro, geothermal, tidal, biogas, natural gas, gas, electricity, etc. (Cao Qunfang).

Air leaks in the line are generally in the joints. Replace the fittings or accessories. It should be noted that there should be no open flame during operation.

The leakage of the biogas pipe needs to be checked first** for air leakage, where the leak is treated.
