Liquid working medium temperature change self circulation power generation device and power generation method

Abstract

The invention relates to a liquid working medium temperature change self circulation power generation device and power generation method, which belong to the technical field of comprehensive utilization of energy. The technical scheme is that: a liquid working medium heating device is arranged in a heater; the liquid working medium is rose in temperature, reduced in density and increased in volume after being heated in the heater; the liquid working medium is driven by buoyancy lift to automatically flow to a water wheel generator along an outlet pipeline on the upper part of the heater to push the water wheel generator to apply work; the decompressed liquid working medium automatically flows back to an inlet on the lower part of the heater from a liquid return pipeline to form a natural circulation loop; and the water wheel generator applies work continuously to generate power. The water wheel generator is introduced to a liquid working medium temperature change self circulation system to convert kinetic energy of the self circulation system into electric energy, so that the power generation method is safe, environment-friendly, energy-saving, water-saving, low-cost, high in power generation efficiency, without cold and heat effects and consumption of cooling water and cooling air, and is a novel power generation method.

Description

technical field [0001] The invention relates to a liquid working medium temperature change self-circulation power generation device and a power generation method, which belong to the technical field of energy comprehensive utilization. Background technique [0002] At present, electricity, as one of the cleanest energy sources, still occupies a dominant position. Electric energy comes from thermal power, hydropower, nuclear power, wind power and solar power, etc. Thermal power generation consumes a lot of non-renewable resources and causes serious environmental pollution; Hydropower generation requires the construction of dams on the river, which damages the ecological environment; nuclear power, wind power, and solar power generation cannot be widely promoted due to high costs; hydropower generation efficiency is 75-98.5%, and the cost of power generation is low, but it is limited by water sources.

[0002] At present, electricity, as one of the cleanest energy sources, still occupies a dominant position. Electric energy comes from thermal power, hydropower, nuclear power, wind power and solar power, etc. Thermal power generation consumes a lot of non-renewable resources and causes serious environmental pollution; Hydropower generation requires the construction of dams on the river, destroying the ecological environment; nuclear power, wind power, and solar power generation cannot be widely promoted due to high costs; hydropower generation efficiency is 75-98.5%, and the cost of power generation is low, but it is limited by water sources. Constraints, accounting for a relatively small proportion; thermal power cogeneration devices have a total efficiency of 60-70%, but due to the limitation of heat demand, the proportion is also small; thermal power condensing turbine power generation occupies a large part of the power generation industry Dominant position, but the cold and heat effect of the power generation process of the condensing turbine is serious, it needs to consume a large amount of cooling water or cooling air, the total efficiency of power generation is only 30-45%, the waste of energy is serious, and the cost of power generation is high
