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...

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...
