Natural gas hydrogen doping control device

Abstract

The utility model provides a natural gas hydrogen doping control device which comprises a natural gas pipeline provided with a natural gas adjusting module. The hydrogen pipeline comprises a first hydrogen pipeline and a second hydrogen pipeline which are connected in parallel, a first hydrogen pipeline adjusting module is arranged on the first hydrogen pipeline, and a second hydrogen pipeline adjusting module is arranged on the second hydrogen pipeline; the natural gas pipeline and the hydrogen pipeline are connected to the gas mixing pipeline after being mixed; the controller is used for adjusting the hydrogen flow of the hydrogen pipeline according to the natural gas flow and controlling the first hydrogen pipeline and / or the second hydrogen pipeline to be opened according to the hydrogen doping amount; wherein the caliber of the first hydrogen pipeline is smaller than that of the second hydrogen pipeline, and the size of the first hydrogen pipeline adjusting module is smaller than that of the second hydrogen pipeline adjusting module. According to the natural gas hydrogen doping control device, two or more hydrogen pipelines are connected in parallel, by opening different hydrogen pipelines, comprehensive coverage of the hydrogen doping proportion from 0% to 100% is achieved, and accurate hydrogen doping under different hydrogen doping proportions is achieved.
