Patent number: 11970415Abstract: The present invention discloses a sludge anaerobic fermentation treatment method with simultaneously enhanced acid production and phosphorus removal. The method includes steps of: (1) adding waste activated sludge into an anaerobic reaction system, with a concentration of a total suspended solid (TSS) of 10000-15000 mg/L; (2) maintaining a pH value of the waste activated sludge at 10±0.1; adding powdery magnetite of 0.3-0.9 g/gVS S. Compared with simple alkaline conditions, in the method of the present invention, an accumulation amount of short chain fatty acids (SCFAs) in a fermentation broth is increased by 20%, and a content of orthophosphoric acid is reduced by 10%. The method can further improve the enhancing effect by using sulfuric acid to modify the magnetite, the accumulation amount of SCFAs can be increased by 36.7% at most, and the content of phosphorus and refractory organic substances can be reduced by 32.4% and 40.4% at most, respectively.Type: GrantFiled: January 15, 2021Date of Patent: April 30, 2024Assignee: ZHEJIANG UNIVERSITYInventors: Liang Zhu, Donghui Lu, Jianxun Chen, Chen Wang, Taixing Han, Xiangyang Xu

Patent number: 11460121Abstract: A safety relief valve for a high-pressure hydrogen cylinder is provided therein with a compression spring and an adjusting nut. The adjusting nut can move up and down to adjust the pressure of the compression spring to compress a sealing plug, so as to adjust the pressure in the hydrogen cylinder to reach an upper limit of pressure relief, which is convenient. Meanwhile, the safety relief valve is provided therein with a fusible seal. When the temperature is lower than a melting point, the fusible seal solidifies, and the sealing plug keeps a gas outlet sealed to prevent hydrogen leakage. When the temperature is higher than the melting point, the fusible seal melts. When the pressure in the hydrogen cylinder is higher than the set upper limit, the sealing plug is forced to open, and the hydrogen flows from an exhaust hole to a hydrogen collection tube.Type: GrantFiled: July 14, 2021Date of Patent: October 4, 2022Assignee: Guangdong OPR Hydrogen Energy Technology Co., Ltd.Inventors: Ming Chi, Yong Bai, Jun Li, Zhiyong Fu, Qiaoying Shi, Donghui Chen

Patent number: 6483846Abstract: A middleware approach to implementation of real-time Ethernet that provides deterministic, i.e. predictable, communication services over the conventional Ethernet network is described. The middleware resides above the network interface device and the device driver, yet below the system transport services and/or user applications. The middleware schedules and controls admission of data packets onto the network and guarantees the real-time constraints of the data packets once they are admitted. Collision of data streams is prohibited during transmission of real-time data, yet collisions are allowed during transmission of soft- or non-real-time data for improved utilization of bandwidth. Bandwidth utilization is further optimized by incorporating a quality of service definition into the scheduling determination.Type: GrantFiled: July 10, 1998Date of Patent: November 19, 2002Assignee: Honeywell Inc.Inventors: Jiandong Huang, Donghui Chen
