Problems solved by technology

[0004] In the second type of absorption heat pump system, its main components are mainly composed of evaporators, condensers, absorbers, generators, heat exchangers, solution pumps, solvent pumps, and connecting pipes, piping and valves connected between various equipment. Among them, the generator and evaporator are heated by a medium-temperature driving heat source, and the output hot water or steam is high-temperature heat energy, which can meet the needs of certain industrial production processes; therefore, the traditional second-type absorption heat pump can only obtain heat energy. Electric energy cannot be output, and cogeneration of heat and power cannot be realized; and the actual high-temperature hot water is obtained from the absorber, and the evaporator is a high-pressure part in the second type of absorption heat pump system, which also needs to consume heat from low-grade heat sources, resulting in the COP of the system reduce

Embodiment Construction

[0016] The specific implementation method of the present invention will be further described below in conjunction with the accompanying drawings.

[0017] The working principle of the cuproammonia primary battery in this application is: both electrodes of the cuproammonia primary battery are copper electrodes. The reaction that takes place is that copper reacts with ammonia to form a copper ammonium complex, and the specific reaction formula is: Cu + 4 NH 3 → Cu(NH 3 ) 4 2+ + 2e - , the reaction at the cathode is that copper ions get electrons and are reduced to copper. The specific reaction formula is: Cu 2+ + 2e - → Cu, which constitutes a primary battery and generates electricity. After the discharge of the primary battery is completed, the anode chamber solution enters the rectification tower, and the copper ammonia complex is rectified by a low-grade heat source to obtain a solution containing copper ions and ammonia gas. The specific reaction formula is: Cu(NH 3...

Abstract

The invention discloses a second-class absorption heat pump capable of outputting electric energy. The heat pump comprises an absorber, a heat exchanger, a throttling valve, a generation tower, a solution pump, a condenser, a solvent pump, a copper ammonia primary battery device and a controller. The heat pump is characterized in that the copper ammonia primary battery device is used for replacing an evaporator of a traditional second-class absorption heat pump system, solenoid valves in the copper ammonia primary battery device are controlled by the controller to switch channels, a cathode and an anode of a copper ammonia primary battery are interchanged after discharging every time, and the copper ammonia primary battery is changed into a regenerative primary battery, so that the system can output the electric energy continuously, and high-temperature water can be obtained in the absorber. Heat sources of the copper ammonia primary battery device and the generation tower of the heat pump can fully utilize low-grade heat sources such as industrial wastewater, process waste heat, solar hot water and the like, so that the system produces higher-grade heat energy and electric energy, combined heat and electricity generation is realized, and energy conservation and emission reduction are realized really.

Description

technical field [0001] The invention relates to a second-type absorption heat pump, in particular to a second-type absorption heat pump that outputs electric energy. Background technique [0002] Energy is an indispensable part of human activities. Today, the energy used in the world is mainly non-renewable fossil energy such as coal, oil, and natural gas. These non-renewable energy sources will decrease and will eventually be exhausted. How to improve the utilization rate of energy It has become an important aspect to solve the energy problem. [0003] In petrochemical, light industry and other industries, there is a large amount of low-grade industrial waste heat, most of which are directly discharged into the environment, which not only causes a huge waste of energy, but also causes thermal pollution of the environment. In recent years, organic Rankine cycle low-temperature waste heat power generation technology, second-type absorption heat pump technology, heat-driven c...
