According to news from July 23, 2025, **information from the Intellectual Property Office shows that Ningxia Baofeng Energy Group Coking Plant No. 2 Co., Ltd. has obtained a patent titled “A low-loss dry quenching device for coking,” with the approval announcement number CN223134397U; the application was filed in September 2024. The patent abstract indicates that this utility model discloses a low-loss dry quenching device for coke production, which includes a furnace body. A nitrogen filling pipe is arranged on one side of the furnace body; the upper end of this pipe is integrally connected to pipe one, and pipe one is in connection with pipe two, which is used for transporting nitrogen. A support plate is placed on one side of the furnace body, and an indentation is provided at the upper end of one end of this support plate. A detection component is mounted rotatably within this indentation, and this component sprays soapy water around the junction of pipe one and pipe two in order to carry out sealing inspections ； The application uses two limit sleeves to clamp and support Pipe 1, thereby keeping it stable. Meanwhile, a support plate is utilized to restrict Pipe 2, ensuring that the joint between Pipe 1 and Pipe 2 remains in a vertical position, which facilitates leak testing. Additionally, through the meshing of a driving wheel and a gear disc, the gear disc causes the spray nozzle to move in a circular motion; the nozzle then sprays in a circular pattern onto the joint between Pipe 1 and Pipe 2. The integrity of the seal can be determined by observing whether bubbles form in the soapy water. This method significantly improves the efficiency of the testing process.
