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.
