Wind energy and geothermal energy combined power generating system

Abstract

The invention discloses a wind energy and geothermal energy combined power generating system that consists of a wind energy generating system and a geothermal energy heat pipe generating system, wherein the wind energy generating system consists of impellers and an engine room, wherein the engine room is internally provided with a transmission system and a generating unit; the geothermal energy heat pipe generating system consists of a geothermal energy heat pipe and a turbine generating system, wherein a body of the geothermal energy heat pipe consists of a pipe wall, a liquid-absorbing coreand a working medium; a chamber body of the geothermal energy heat pipe consists of an evaporating chamber, a condensing chamber, a gradually-shrunk pipe chamber, a vacuum heat insulating chamber anda spraying nozzle; and the turbine generating system consists of a multi-stage blade, a supporting mechanism, a bearing, a rotating shaft, a magnetic fluid sealing device and a generating unit. By adopting the wind energy and geothermal energy combined power generating system, the extracting and the back-filling of geothermal resource are not required, the wine energy and the geothermal energy are utilized effectively, the running and the maintenance processes are green and environment-friendly, the running cost and the maintenance cost are low, the power generation is continuous and stable, the generating efficiency is high, practical contributions can be made on aspects such as the development and the utilization of new energy, and the energy saving and the emission reducing, and the sustainable development of circulated economy and the long-term development of low-carbon economy and green economy can be promoted.

Description

technical field [0001] The invention relates to a wind energy power generation system, and also relates to a geothermal energy power generation system, in particular to a combined wind energy and geothermal energy power generation system. Background technique [0002] According to the Medium and Long-Term Development Plan for Renewable Energy published by the National Development and Reform Commission, “Energy is an important material basis for economic and social development. The rapid consumption of resources, the continuous deterioration of the ecological environment, especially the increasingly severe global climate change caused by greenhouse gas emissions, have seriously threatened the sustainable development of human society. At present, my country has become a major energy production and consumption country in the world, but the per capita energy consumption level is still low. Very low. With the continuous development of the economy and society, my country's energy de...

Problems solved by technology

However, in the process of using underground natural steam and hot water in geothermal power stations, minerals or impurities contained in geothermal resources will cause certain corrosion and damage to related equipment in direct contact with it, which is not conducive to the long-term maintenance of equipment. Stable operation, and continuous extraction and recharge of geothermal resources, will also affect and destroy the distribution of geothermal resources, geological structure and ecological environment in the area where it is located, causing a series of problems

On the other hand, with the continuous strengthening of the protection of groundwater resources, the direct use of geothermal water resources will be more restricted
