Abstract

The invention relates to a hydrogen-doped natural gas technology, and aims to provide a device and a method for testing gas component distribution in hydrogen-doped natural gas. The device comprises: a stirring kettle internally provided with a stirring paddle, wherein the inlet of the stirring kettle is respectively connected with a natural gas cylinder group and a hydrogen cylinder group through pipelines; a vertical gas cylinder, wherein at least three layers of partition plates are arranged in the vertical gas cylinder, and can be controlled by valves to be opened and closed so as to form mutually independent internal partitions; a pneumatic booster pump respectively connected with the stirring kettle and the vertical gas cylinder; a plurality of gas outlets formed in the wall of the vertical gas cylinder and connected with a chromatographic analyzer through pipelines, wherein each gas outlet corresponds to one internal partition; and a control system connected to the chromatographic analyzer, the stirring paddle and the driving motor of the pneumatic booster pump through signal lines. According to the testing device and the testing method provided by the invention, the gas component distribution of hydrogen-doped natural gas in a high-pressure gas cylinder in a station yard after long-term standing layering can be conveniently and accurately measured.

Description

technical field [0001] The invention belongs to the technology of hydrogen-doped natural gas, in particular to a device and method for testing the distribution of gas components in hydrogen-doped natural gas. Background technique [0002] With the continuous optimization of my country's energy structure, renewable energy is developing rapidly. Although renewable energy represented by wind energy and solar energy is developing rapidly, the intermittent and unpredictability of wind / solar power generation limits its large-scale integration into the main power grid. In particular, the unbalanced distribution of wind / light geographical resources in my country has led to the separation of power generation centers and load centers, causing serious "abandonment of wind and power cuts" for its large-scale application. [0003] Hydrogen is produced from excess wind power or photoelectric water splitting, and the hydrogen is mixed with natural gas to form hydrogen-doped natural gas (H...
