  • Patent number: 12005431
    Abstract: A reaction apparatus used for a continuous reaction process for the preparation of trifluoroethane includes a housing, a rotary cutting component, a submersible pump and a flow deflector. The flow deflector includes two sets of flow-deflecting plates, each set of said flow-deflecting plates including a plurality of flow-deflecting plates. Two sets of flow-deflecting plates are fixed to each of the two opposing side walls, and the two adjacent flow-deflecting plates are in offset alignment. The submersible pump is arranged inside the reaction chamber body. A liquid inlet line can connect a directly to the submersible pump without requiring the arrangement of an additional pipeline.

  • Publication number: 20240149170
    Abstract: Disclosed are a game data verification method performed by an electronic device. The method includes: generating a target sequence of target nodes in response to a game start instruction; acquiring target game data corresponding to each of the target nodes, the target game data including game state data and encrypted state data; performing authenticity verification on the target game data of a current target node according to the encrypted state data of a previous target node and the game state data of the current target node; performing accuracy verification on the target game data of the current target node according to the game state data of the current target node and game logic; and after determining that all the target game data corresponding to the target sequence is authentic data and accurate data based on an authenticity verification result and an accuracy verification result, determining that the game verification succeeds.

  • Publication number: 20240076277
    Abstract: A system and method for preparing epoxy chloropropane is provided in that by coupling three stages of high gravity reactors, the product epoxy chloropropane and water vapor are distilled from a reaction system in form of an azeotrope by adopting a water vapor steam stripping method. Further, by combining the azeotrope with the multiples stages of high gravity reactors, the gas phase mass transfer and the liquid phase mass transfer of the azeotrope are improved aiming at the features of the azeotrope in the reaction system, thus making the overall conversion rate higher. In addition, by combining steam stripping and high gravity, dichloropropanol and alkali solution are rapidly mixed for mass transfer, and the product epoxy chloropropane is rapidly distilled from the reaction system in the form of the azeotrope, such that the reaction proceeds continuously towards the direction of producing epoxy chloropropane, thus significantly improving the conversion rate.
