On March 29, news reported that the National Intellectual Property Administration of China indicated that China Energy Engineering Group Co., Ltd., China Energy Construction Digital Technology Group Co., Ltd., and China Energy Construction Deep Earth Technology (Hubei) Co., Ltd. applied for a patent titled “Gas Injection Pipeline Flow Guiding Cooling Device and Cooling Method for Tunnel-type Gas Storage.” The authorization announcement number is CN120384781B, and the authorization announcement date is March 27, 2026. The application publication number is CN120384781A, the application number is CN202510485042.7, the application publication date is March 27, 2026, and the application date is April 17, 2025. The inventors are Li Jun, Wan Mingzhong, An Xiaoyu, Zhao Rui, Ji Wendong, Wang Qi, and Cheng Shaozhen. The patent agency is Beijing Qinyou Intellectual Property Agency Co., Ltd., and the patent agent is Guo Na. The classification numbers are E21F17/16, E21F3/00, and E21F17/00.

The patent abstract shows that the invention discloses a gas injection pipeline flow guiding cooling device and its cooling method for tunnel-type gas storage. This device is applied within the gas storage to change the internal air distribution of the gas storage, achieving a reduction in the top temperature of the gas storage and increasing the speed of gas injection into the storage. The device includes: a manhole pipeline, a swing pipe, a top pipeline, multiple gas outlets, and a supporting mechanism. The method is applicable to the aforementioned gas injection pipeline flow guiding cooling device in the tunnel-type gas storage. By using this device, the intake pipeline at the lower part of the gas storage is introduced to the top of the gas storage, and through the gas outlets at the top and the end, the temperature field distribution inside the gas storage is altered to achieve the purpose of lowering the top temperature and improving the gas injection speed.
