Publication number: 20240142061Abstract: Disclosed is an anti-leakage device for a hydrogen storage container. A sealing assembly is connected to a right side of a tank body of an anti-leakage device, an impurity removing assembly is connected to a lower side of the tank body, and the impurity removing assembly is connected to the sealing assembly. By adopting the technical solution above, if the leakage occurs from the hydrogen storage container, hydrogen leaks into an inner cavity of the tank body, and an anti-leakage effect is achieved by intercepting and collecting the hydrogen. With the increase of the amount of hydrogen collected in the inner cavity of the tank body, an air pressure in the tank body increases, and a high-pressure gas pushes a first linkage block and a sealing sleeve to move to the right, making the contact between the sealing sleeve and a first cylinder closer.Type: ApplicationFiled: October 17, 2023Publication date: May 2, 2024Inventors: Xiang Li, Jiepu Li, Xin Ma, Yitao Liu

The sprayer body is provided with a swirl generator for generating a swirling air stream, and a power supply connected between the nozzle and the partition, to apply voltage to the nozzle and the partition. The electrospray device may be part of a fluidized bed apparatus comprising a product container, a lower plenum base, an air distribution plate resided therebetween. When the power supply applies voltage in opposite polarities to the nozzle and the partition, the fluidized bed apparatus is used for coating particles; and when the power supply applies voltage of the same, the fluidized bed apparatus is used for spray-drying a solution. The electrospray device uses an electromagnetic hydrodynamic method to improve the performance of the fluidized bed apparatus and optimize the process of product.Type: GrantFiled: October 16, 2017Date of Patent: December 19, 2023Assignee: Tianjin Cenax Biotechnology Co., Ltd.Inventors: Yiming Liu, Huifen Lu, Fei Liu, Yitao Liu, Min Chen

Patent number: 11165251Abstract: A symmetric method for obtaining network-power-loss components induced by sources and loads at individual buses in AC power networks is invented. Two linear expressions of bus injection active and reactive powers in terms of translation voltages and voltage angles of all buses are established at first. Then a linear symmetric matrix-equation model for the steady state of the network is built. Manipulating this model by Moore-Penrose pseudoinverse produces a linear symmetric matrix expression of translation voltages and voltage angles of all buses in terms of bus injection powers. Expressing the network power loss in terms of source's and load's powers by this matrix expression, a symmetric algebraic calculation formula for obtaining the network-power-loss components is produced after manipulating by Shapley value theorem, by which the obtaining of network-power-loss components are achieved. The set of network-power-loss components provides a new efficient tool for economic operation of AC power networks.Type: GrantFiled: January 28, 2019Date of Patent: November 2, 2021Assignee: SHENZHEN UNIVERSITYInventors: Hui Jiang, Jianchun Peng, Yitao Liu
