High-pressure gas potential enthalpy circulation type power generation device

Abstract

The invention discloses a high-pressure gas potential enthalpy circulation type power generation device. The high-pressure gas potential enthalpy circulation type power generation device comprises a gas heating pipe, a gas cooling pipe, a steam turbine generator set, a heat exchanger, a cool exchanger and a high-pressure gas working medium, the gas heating pipe communicates with the gas cooling pipe at the low-position end, the gas heating pipe and the gas cooling pipe communicate with the steam turbine generator set at the high-position end, the gas heating pipe exchanges heat with hot seawater outside the pipe through the heat exchanger, the gas cooling pipe exchanges heat with cold seawater outside the pipe through the cool exchanger, and the high-pressure gas working medium is arrangedin pipelines of the gas heating pipe and the gas cooling pipe. By implementing the high-pressure gas potential enthalpy circulation type power generation device, the following beneficial effects thatthe energy collection cost is reduced, the intensification is relatively high, large-scale development can be achieved, the cost is reduced, and the cost of electricity of per kilowatt hour is reduced are achieved.

Description

Technical field [0001] The invention relates to the field of thermoelectric power generation, in particular to a high-pressure gas potential enthalpy cycle power generation device. Background technique [0002] There is a basically constant temperature difference of 20~25℃ between the ocean surface in the tropical zone and the depth of several hundred to thousands of meters, which provides a huge and stable cold and heat source for power generation, with 50 billion kilowatts of exploitable Power generation capacity, seawater absorbs solar energy, stable supply, and can generate electricity day and night. It is an important new energy system that can provide most of the energy needed by humans. [0003] Due to the low energy density of ocean temperature difference, cold sea water is at a depth of hundreds to thousands of meters. The current power generation methods mainly include open cycle, closed cycle, hybrid cycle, droplet lifting, etc. Due to the low temperature difference, the...

Problems solved by technology

[0003] Due to the low energy density of the ocean temperature difference, cold seawater is at a depth of hundreds to thousands of meters. The current power generation methods mainly include open cycle, closed cycle, mixed cycle, droplet lifting, etc. Due to the low temperature difference, the thermal efficiency is not good. High, there are high energy collection costs, low intensification, and the inability to reduce costs through large-scale development. The project investment is large, the cost of electricity is high, and commercial operation cannot be realized
