Abstract: The present invention provides a chemical heat pump with a multi-channel membrane reactor, comprising: a feeding pipe, a liquid phase pump, a first solenoid valve, a multi-channel waste heat recovering membrane reactor, a discharging pipe, a remainder reflowing pipe, a heat regenerator, a second solenoid valve, a high-temperature heat release reactor, and a third solenoid valve. The feeding pipe is sequentially connected to the liquid phase pump, the first solenoid valve, and a feeding port of the multi-channel waste heat recovering membrane reactor; and a discharging port of the multi-channel waste heat recovering membrane reactor is sequentially connected to the heat regenerator, the second solenoid valve, the high-temperature heat release reactor and the third solenoid valve via the discharging pipe, and is then connected to the heat regenerator and an inlet of the liquid phase pump, and a remainder reflowing port of the multi-channel waste heat recovering membrane reactor is reconnected to the inlet of the liquid phase pump via the remainder reflowing pipe. According to the present invention, a working medium subjected to the heat absorption reaction of the chemical heat pump is separated through a membrane, such that the heat consumption of a reboiler and the cold consumption of a condenser in a distillation column can be avoided, a sufficient separation is achieved, and the reaction conversion rate and the heat efficiency of a chemical heat pump system can be improved.

Abstract: A hydrogel capable of desalinating seawater and a preparation method thereof. The hydrogel is a polymer polymerized by a monomer containing a hydrophilic group and a carbon-carbon double bond via carbon-carbon double bonds. A degree of crosslinking of the polymer is 0.01 to 0.2. The monomer accounts for 5 wt % to 50 wt % of a mass of the hydrogel. The preparation method includes: mixing a monomer with a pore-forming agent, a cross-linking agent, a initiator and a catalyst evenly, obtaining a mixed material, then transferring the mixed material into a die; conducting a polymerization for 2 to 3 hours at a temperature of 20° C. to 30° C. first, followed by increasing the temperature to continue the polymerization until the polymerization is completed; and obtaining the hydrogel capable of desalinating seawater. The method according is convenient and efficient, and has advantages of being used under special conditions such as earthquake relief work, maritime rescue and wild adventure.
