Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of natural gas hydrogen mixing, and in particular relates to a natural gas hydrogen mixing system. Background technique [0002] With the development of society, primary energy dominated by fossil fuels such as petroleum and coal cannot meet the demand. Environmental pollution, the greenhouse effect and the gradual depletion of fossil energy make it urgent to find new clean energy. Hydrogen energy is a clean secondary energy carrier, which has been widely concerned at home and abroad for a long time. Among them, safe and efficient hydrogen transportation technology is one of the main bottlenecks in the large-scale application of hydrogen energy. Pipeline transportation of hydrogen has a large volume and low cost, but special hydrogen pipelines need to be built. [0003] Natural gas hydrogen mixing hydrogen transmission technology is a new hydrogen transmission scheme proposed by developed countries in rece...
