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 acting work, in particular to an ammonia water reheating-ejection absorption power cycle system driven by seawater temperature difference. Background technique [0002] The current ocean temperature difference power generation device is mainly a closed Rankine cycle device. The closed Rankine cycle device is mainly composed of evaporator 1', steam turbine 2', condenser 3' and solution pump 4'. The device uses low boiling point working fluids, such as propane, isobutane, Freon, ammonia, etc. Substance, relying on the gas generated by the heat absorption and evaporation of the working fluid in the evaporator 1' to drive the steam turbine 2' to rotate and do work externally, 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 outlet of the condenser 3' The inlets are connected, and the exhaust steam aft...

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 casing 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.
