The invention relates to a
hydrogen mixing
system for
natural gas. The
hydrogen mixing
system for the
natural gas comprises a
hydrogen gas source, a hydrogen
gas pressure regulating mechanism, a hydrogen gas
buffer tank, a
natural gas source, a natural
gas pressure regulating mechanism and a
mixing tank; the hydrogen gas source, the hydrogen
gas pressure regulating mechanism and the hydrogen gas
buffer tank are sequentially arranged on a hydrogen gas input pipeline, the
hydrogen pressure regulating mechanism is used for regulating the
gas supply pressure of hydrogen gas, the hydrogen gas
buffer tank is used for storing hydrogen gas and buffering and stabilizing pressure; the natural gas source and the natural gas pressure regulating mechanism are sequentially arranged on a natural gas input pipeline, the natural gas pressure regulating mechanism is used for regulating the
gas supply pressure of natural gas; and the
mixing tank is connected with the
tail ends of the hydrogen gas input pipeline and the natural gas input pipeline, is connected with a
fuel gas main
pipe network, and is used for uniformly mixing the input hydrogen gas and natural gas and outputting a mixture to the gas main
pipe network for transmission and distribution. Pressure regulation is carried out on the input hydrogen gas and natural gas through the pressure regulating mechanisms, so that the
gas supply pressure meets the mixing pressure, and it is guaranteed that hydrogen mixing of the natural gas in the
mixing tank is smoothly carried out through
pressure stabilization of the hydrogen gas buffer tank, the problem of large-scale hydrogen transportation can be solved without construction of a hydrogen transportation
pipe network, and the hydrogen mixing
system for the natural gas has a wide application prospect.
