Low-temperature difference air heat power generation method

Abstract

The invention relates to a low-temperature difference air heat power generation method. Normal-temperature air is absorbed in atmosphere and, 65-DEG C hot air is obtained by increase of a heat pump and fed into a heat-preservation water tank with specific height, so that the temperature of the water tank can achieve 60 DEG C. A rotational structure device arranged in the water tank is provided with a thermal-operated device (1), a laminated memory alloy butterfly spring in the thermal-operated device (1) is sunk in 60-DEG C hot water from a martensite configuration under normal temperature, and is heated and changed into an austenite configuration so as to enable a variable-capacitance valve (13) of the thermal-operated device (1) to move and the buoyancy of an energy transduction tube (19) to be increased, the energy transduction tube (19) emerges from the water, the austenite configuration enters the normal-temperature atmosphere, and is evaporated and cooled so as to enable the laminated memory alloy butterfly spring to be changed into the martensite configuration once again and enter in the hot water. The process is circulating again and again, thus generating mechanical rotation movement and driving a power generator for power generation. The low-temperature difference air heat power generation method has the advantages of having exhaustible clean energy, being high-efficiency and easy to maintain, having no high temperature and no pollution and being green and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a low temperature difference air heat power generation method. Background technique [0002] With the consumption and shortage of global petrochemicals including oil and coal, as well as the greenhouse effect and pollution, people are paying attention to renewable natural energy in addition to nuclear energy. In fact, the sources of renewable energy all come from the sun, including solar energy, wind energy, water conservancy energy, combustible plants and so on. Solar energy is absorbed by the atmosphere and turned into meteorological energy. The meteorological energy in the atmosphere, wind energy and hydraulic energy guided by rainwater have been utilized. Direct solar energy, such as photovoltaic power generation, is in the ascendant, but the thermal energy in the air and seawater is affected by the laws of thermodynamics (temperature difference problem) and fewer ...

Problems solved by technology

But now in the atmosphere, how to use the heat energy in the ocean? The temperature difference between the surface layer and the deep layer of seawater can reach 15-20 degrees, and the entropy value of the low-boiling-point working fluid of the alkanes is used to drive the steam turbine to generate electricity, but the cost, cost, risk, and corrosion are all very challenging, and the remote transmission of electricity is also expensive. project
