Problems solved by technology

However, the current old geothermal power generation process has low thermal efficiency; the waste is extremely serious, and the temperature of geothermal water is required to be relatively high; while the widely existing hot water flowing from the ground with a temperature of only about 40°C cannot be used and made into natural gas. great waste of resources

Embodiment Construction

[0007] The geothermal water is pumped to the multifunctional vacuum circulating water tank. Since the temperature of the multifunctional vacuum circulating water tank is controlled below 5°C, the heat with a temperature higher than 5°C will turn into steam and be recovered by the multifunctional steam recovery bin.

[0008] The steam recovered from the multi-functional steam recovery chamber is transformed into a supercritical liquid by the medium-pressure steam chamber, high-pressure steam chamber, and supercritical pressure cylinder, and then sprayed on the steam turbine to expand rapidly, turning into high-temperature and high-pressure water vapor to drive the steam turbine to generate electricity. The low-temperature and low-pressure water vapor after work is sent to the multifunctional vacuum circulation water tank by the air extractor. The water vapor that does not turn into water is forcibly sent to the multi-functional steam recovery bin by multiple powerful air extrac...

Abstract

The process flow of a geothermic electropower station has the main technical characteristics that a corrosion resistant multifunctional vacuum circulating water sump is used for converting the heat of corrosive geothermal water into steam, then the steam is recovered by a multifunctional steam recovering cabin; the recovered steam is compressed and heated layer by layer to finally form high temperature and high pressure water vapor reaching the supercritical pressure, and the water vapor is used for driving a steam turbine to generate electricity; furthermore, after doing work, the whole low temperature and low pressure water vapor is discharged and recovered, so as to realize circulating power generation.

Description

technical field [0001] The invention relates to the technical field of using the heat of hot water to generate high-temperature and high-pressure steam to drive a steam turbine to generate electricity. Background technique [0002] Thermal power generation is the largest source of pollution and the largest industrial water consumer in the world. For example, the current annual water consumption of thermal power generation in the United States is 272.5 billion cubic meters, which is equivalent to the annual water consumption of five Yellow Rivers in China. There is sufficient evidence to prove that global warming, acid rain increase, disastrous weather increase and intensification, mass extinction, etc. endangering the living environment of human beings are all directly related to thermal power generation. [0003] Coal is the main source of energy in our country, and it is also the main source of environmental pollution in our country. According to the 20 most polluted cit...
