Description

Technical Field

[0001] This utility model relates to the field of gas, and in particular to an online dredging device and system for gas pipeline drainage pipes. Background Technology

[0002] During the steel production process, a large amount of metallurgical gas is generated. As a combustible gas that can be reused, metallurgical gas can be used as fuel in many processes within the steel industry. Because the processes using metallurgical gas in steel enterprises are numerous and widely distributed, gas pipelines are needed for long-distance transportation and distribution. During transportation, as the temperature and pressure of the metallurgical gas decrease, trace amounts of moisture and dust impurities in the gas condense and accumulate at the bottom of the gas pipeline, causing corrosion and affecting user experience. This can lead to burner blockage, poor combustion, or even flameout. Therefore, gas drainers are installed at intervals along the gas pipeline to remove the water and impurities that have condensed and accumulated at the bottom of the pipeline.

[0003] The currently used gas drainer is a vertically installed drain pipe, with its top end installed on the bottom of the gas pipeline, used to drain water and impurities from the gas pipeline to the outside. As the gas drainer operates for longer periods, scale and blockages will gradually occur in the drain pipe. If the blockage occurs below the primary valve, the drain pipe can be cleared online after closing the primary valve. However, if the blockage occurs above or at the primary valve, online clearing is not possible; the gas pipeline must be shut down for gas treatment before clearing can be performed. This method is less efficient and economical, and forcibly clearing the blockage online poses a significant safety hazard. Utility Model Content
