The existing decompression equipment is generally designed for natural gas, and there are few decompression equipment for biogas. In addition, the existing biogas decompression equipment has the following defects that need to be improved:

[0003] 1. The existing biogas decompression equipment does not have the desulfurization link of biogas. The long-term use of sulfur-containing biogas is not conducive to the service life of the back-end gas pipeline and combustion equipment, and is likely to cause damage to the gas pipeline and combustion equipment, and even endanger personal safety;

The volume of each bottle is 205L, and the filling pressure is 20Mpa. The gas cylinder group 1 is connected to the first ball valve 3 through the hose 2. The first ball valve 3 is opened, and the biogas in the gas cylinder group 1 flows into the filter 6. The filter 6 filters the solid impurities in the biogas. The filtered biogas enters the electric heater 12. The power of the electric heater 12 is 8kw. The electric heater 12 is used to keep the temperature of the biogas constant. Then the biogas enters the first-level pressure regulating part 9 through the pipeline. The first-level pressure regulating part 9 regulates the pressure value of the biogas from 20Mpa to 2-4Mpa. The biogas after pressure regulation enters the electric heater 12 to keep the temperature of the biogas constant.

The second-stage pressure regulating part 18 and the third-stage pressure regulating part 28 are respectively composed of one-way pressure regulator 16. The first-stage pressure regulating part 9 has a larger regulating pressure value for biogas, so four-way pressure regulators 16 are used in parallel for regulation.

[0029] Specific implementation method three: Combination Figure 1-Figure 2 The present embodiment is described as a mobile pressure regulating integrated gas supply equipment, wherein the input end of the first-stage pressure regulating part 9 is connected with a first temperature sensor 10 and a first pressure gauge 11, and the output end of the first-stage pressure regulating part 9 is connected with a second pressure sensor 15.

A flow sensor 32 is installed between the torch 31 and the first pipeline 34. The five safety valves on the gas supply device are brought together and lead to the torch 31 through the first pipeline 34.

When natural gas leaks, in order to be easily discovered by people, the natural gas is odorized. The odorization standard is that it can be detected when the lower explosion limit concentration is reached. The odorized gas flows into the three-stage pressure regulating part 28 and passes through the hydrogen sulfide sensor 24 for detecting the hydrogen sulfide concentration in the gas. At the same time, a second emergency shut-off valve 25 is installed between the odorizer 23 and the three-stage pressure regulating part 28, so that it can be shut off urgently when the gas leaks or does not meet the standard.
