Ammonia water reheating-injecting power absorption circulation system driven by temperature difference of seawater

Abstract

The invention relates to the field of working by using temperature difference of seawater, in particular to an ammonia water reheating-injecting power absorption circulation system driven by the temperature difference of the seawater. The system comprises a generator, gas-liquid separators and a steam turbine, wherein the steam turbine comprises a primary steam turbine and a secondary steam turbine. The gas channel outlet of the generator is communicated with an inlet of the primary steam turbine through the gas-liquid separator I. The outlet of the primary steam turbine is communicated with an inlet of a reheater through a pipeline. The outlet of the reheater is communicated with the gas-liquid separator II through a pipeline. The liquid outlet of the gas-liquid separator II is communicated with a working fluid inlet of a secondary injector through a pipeline. The gas outlet of the gas-liquid separator II is communicated with an inlet of the secondary steam turbine through a pipeline. The outlet of the secondary steam turbine is communicated with a gas inlet of an injecting absorption heat exchanger through a pipeline. The first outlet of the injecting absorption heat exchanger is communicated with a gas sucking inlet of the secondary injector through a pipeline. The outlet of the secondary injector is communicated with inlets of a solution pump and a solution heat exchanger through pipelines. By virtue of the system, the circulation efficiency is greatly improved.

Description

Technical field [0001] The invention relates to the field of seawater temperature difference work, in particular to an ammonia water reheating-ejection absorption power cycle system driven by seawater temperature difference. Background technique [0002] The currently used ocean thermoelectric power generation devices are mainly closed Rankine cycle devices. The closed Rankine cycle device is mainly composed of an evaporator 1', a steam turbine 2', a condenser 3'and a solution pump 4'. The device uses a low boiling point working medium, such as propane, isobutane, freon, ammonia, etc. Substances, relying on the gas produced by the working fluid to absorb heat and evaporate in the evaporator 1'to drive the turbine 2'to rotate and perform external work. The outlet of the evaporator 1'is connected to the inlet of the steam turbine 2', and the outlet of the compressor is connected to the condenser 3'. The inlet is connected, and the exhaust steam after external work is sent to the c...

Problems solved by technology

[0003] However, the evaporation-condensation of the above-mentioned working fluid is a physical process, and its power generation is limited by the latent heat value of the phase change of the working fluid, thereby limiting the cycle efficiency; in addition, most of the absorbers used in engineering are sleeve-type absorbers, bubbler Absorbers and Membrane Absorbers

The existing absorber has the shortcomings of small contact area between liquid and gas, insufficient contact with the cooling wall, large solution filling volume, which is not conducive to heat exchange, etc.
