An Artificial Density Difference Power Generation System

Abstract

The invention discloses an artificial density difference power generation system comprising a working medium gas generation device, a density difference forming device and a power generation unit, fluid can continuously flow in a communication structure under the action of density difference of gas-liquid two-phase flow and one-phase flow in the density difference forming device to drive the power generation unit to generate power. The artificial density difference power generation system can utilize the existing conventional heat sources such as terrestrial heat, solar energy, industrial waste heat, ocean thermal energy and other medium-low temperature heat sources, also can utilize wind energy and internal energy contained in gases such as compressed gas, liquefied natural gas and the like, and converts the internal energy contained in the working medium gas into mechanical energy of working fluid by an artificial density difference mode and uses a water turbine for power generation, and therefore, the artificial density difference power generation system has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of power generation devices, in particular to an artificial density difference power generation system. Background technique [0002] With the development of economy and society and the continuous advancement of science and technology, power generation technologies closely related to people's lives are also increasingly developed, such as buoyancy power generation, geothermal power generation, solar power generation, etc., but traditional power generation technologies and related systems have various problems and bugs. [0003] The existing buoyancy power generation technology system is complicated, and most of them use various forms of containers or special devices. By accumulating gas in the device and displacing a corresponding volume of water to generate buoyancy, the power generation device is driven to rotate and the generator to generate electricity. Most geothermal power generation uses geothermal s...

Problems solved by technology

The above-mentioned thermal energy utilization methods all need to use steam turbines to do work for power generation. In order to improve the power generation effect, the temperature of the heat source has to be increased, which will correspondingly limit the development of medium and low temperature geothermal and ordinary small medium and low temperature solar power generation devices, which is not conducive to the development of clean energy. Utilization and development, and because the temperature difference between the medium and low temperature heat source and the cooling water is not large, the corresponding system power generation efficiency is not high, which is also the reason why the medium and low temperature geothermal power generation cannot be applied and the medium and low temperature solar collectors are only used for heating

[0004] In view of the defects of the above various power generation devices, the present invention mainly overcomes that the current medium and low temperature heat sources cannot be efficiently utilized, similar to medium and low temperature solar energy, geothermal heat, and industrial waste heat cannot be efficiently utilized, the investment cost of wind power generation devices is high, the operation and maintenance are difficult, and the wind power Power generation is greatly affected by the weather, and it does not have the disadvantages of high-power energy storage. The efficiency of ocean temperature difference power generation is extremely low, and a large amount of plant power is consumed during the operation of the power generation device.
