Description
Technical field
The utility model belongs to field of electrical equipment, particularly a kind of low form organic Rankine circulating air thermal source temperature difference electricity generation device.
Background technique
Electricity is indispensable a kind of resource in current people's life and production, along with improving constantly of people's living standard, to the demand of electric power resource also by increasing, particularly in summer and winter, power supply is all very nervous, although the way of production of electric power is more at present, has not enough separately place, thermoelectricity is not renewable energy sources, needs the fossil fuel such as coal combustion, oil.Fossil fuel reserves are limited on the one hand, more burning is fewer, is being faced with exhausted danger.Thermoelectricity will consume disposable fossil resource, no matter be coal, oil or rock gas, a large amount of carbon dioxide etc. that discharge, are the generally acknowledged reasons that causes global climate abnormal simultaneously; The sulfur dioxide of burning coal discharge etc. is also the arch-criminal of acid rain.And northern coal is transported to south generating, also take many transport resources and the energy.The generated energy of thermoelectricity almost accounts for 80% of Chinese gross generation at present, and the rate for incorporation into the power network of thermoelectricity is higher than water power, but lower than solar energy, also lower than wind-powered electricity generation.The common fault of renewable energy power generation, that is exactly high cost.Although present solar electrical energy generation is not subject to the impact in region, the efficiency that solar radiation is converted to electric energy by solar panel is too low, and floor space is larger, and price is high, so should not popularize.In addition the environmental pollution, causing in production Related product process is also denounced by people.And wind-power electricity generation, its main power is to blow against wind, so be subject to the impact in weather and region, its rate for incorporation into the power network is higher, is only second to solar energy, but wind-powered electricity generation unstable (electrical network is referred to as rubbish electricity), therefore dispatching of power netwoks is not positive, and when winter, wind was large, robs load with thermoelectricity.Although unlike solar electrical energy generation cost costliness just like that, hydroelectric development needs to pay great human cost.Building water power plant may cause local resident to move.This is also problem of greatest concern in current hydroelectric development.River improvement is also the water power a great problem facing that generates electricity.In order to tackle flood tide, conventionally need to build in area, river mouth dam.But do like this except meeting raising construction cost, bring the problems such as soil erosion also easily to dirty area.Nuclear power is clean energy resource, and power generation stabilization, rate for incorporation into the power network and thermoelectricity are quite or slightly high.But the nuclear fuel material of nuclear power, nuclear safety, nuclear waste problem are perplexing the mankind always.Nuclear energy power generation can produce nuclear waste, has a large amount of radioactive materials in the reactor of nuclear power plant, can cause nuclear pollution once nuclear power station goes wrong, very harmful.
National governments abandon tradition, the high-carbon row energy gradually, as coal, oil, rock gas etc., then use renewable energy sources to become following main trend.Although from the angle of environmental protection, more use renewable energy sourcess are large trend naturally, and high cost has also become the maximum of Renewable Energy Development to hinder, and even threatens energy security.How to improve to use generating efficiency and to reduce cost of electricity-generating and become the most significant problems that Renewable Energy Development institute must solution.
And airborne heat energy comes from the radiation of the sun, belong to renewable inexhaustible endless nature energy again.The heat energy of getting air is used for generating electricity, and should be a good approach.Particularly the south of China is extremely hot weather for a long time, and these extremely hot weather provide advantageous supremacy clause for air heat energy generates electricity.The cold and hot temperature difference can be used for generating at 16.6 DEG C in theory, if adopt the heat of air as heat source; Adopt the low temperature of the underground deep layer in soil and desert; Or river, lake water, seawater, and the low temperature of Deep Underground is condensation low-temperature receiver, can realize this temperature difference.Therefore the heat energy of air can be used for thermo-electric generation.In addition, along with the raising of living condition, increasing air-conditioning and other main equipments are applied among life, production, these equipment can produce a large amount of heats, greenhouse effect are not only aggravated, and the electric energy that has caused its use very major part be converted into heat energy and distribute in air, cause energy utilization rate not high, energy waste is serious.
