Abstract

The invention relates to a method used to stabilize CNG high-flow air feed. A device comprises a collecting pipeline used to collect natural gas released by each tank car. The collecting pipeline comprises a main pipe and branch pipes arranged on the main pipe. The air inflow end of each branch pipe is respectively connected with the air outlet of the tank car. The air outlet end of the main pipe is provided with a main pipe pressure measuring device and a flow measuring device. Each branch pipe is respectively provided with an automatic control valve. The pipe body of each branch pipe between the automatic control valve and the tank car is respectively provided with a branch pipe pressure measuring device. A control device receives signals acquired by the branch pipe pressure measuring devices, the main pipe pressure measuring devices, and the flow measuring device, and analyzes and processes the signals and regulates on-off state of each automatic control valve according to analysis results. In the above technical scheme, the control device regulates on-off state of each automatic control valve, so that the output end of the main pipe can stably provide high-flow air feed, and high-flow air feed requirements of users are satisfied.

Description

technical field [0001] The invention relates to the field of CNG gas supply equipment, in particular to a method for stabilizing CNG large flow gas supply. Background technique [0002] At present, in areas not covered by the domestic natural gas pipeline business, if users use compressed natural gas for large-flow (10,000 to 15,000 m3) gas supply, they generally need to add large-scale gas storage facilities (such as large spherical tanks) for buffer gas supply. To ensure stable gas supply; however, large-scale gas storage facilities are expensive and occupy a large area. Therefore, it is necessary to provide a solution that can stabilize gas supply without using large-scale gas storage facilities. Contents of the invention [0003] The purpose of the invention is to provide a method for stabilizing CNG large-flow gas supply, which can stabilize CNG large-flow gas supply without using large-scale gas storage facilities. [0004] To achieve the above object, the invention...
