Abstract
The invention relates to a technique of a water supply, heat supply and cold supply power plant by trans-critical carbon dioxide to absorb air, water and solar heat, which is characterized in that the physical thermodynamical properties of carbon dioxide and water are used to absorb the heat from the solar radiation, the air and the water by heat pump equipment so as to produce the high-temperature and high-pressure steam to generate electricity. During the power generation, water supply, heat supply, chilled water supply and the like can be conducted. Under the condition of higher air humidity, a heat absorption system of the power plant also can absorb the moisture in the air, which is used by the people. The invention is suitable for be located in the urban area with a natural water source.
Description
Technical field:
The present invention relates to utilize the physical thermodynamics character of carbon dioxide and water,, absorb the heat of solar radiation and environment temperature by heat-pump apparatus.Carry out the technical field of heat supply, cooling, water supply and generating.
Background technology:
The energy is the essential of human survival.Present human combustion fuel obtains the method for the energy, has begun to have developed into the stage of harm humans existence itself.Have ample evidence to prove: the problem that global warming, acid rain increase, the desert constantly enlarges, diastrous weather comprises the continuous increase of sandstorm weather and reinforcement, a large amount of species extinction, a large amount of carcinogenic substance contaminated air, food and water source etc. are extremely serious all has direct relation with the method that human combustion fuel obtains the energy.
Coal is the main force of the present energy of China, also is the main source of making China's environmental pollution.The world enumerated of the World Bank pollutes in 20 the most serious cities according to calendar year 2001, and China occupies 16.The loss that China's atmosphere pollution is made has accounted for 3%～7% of G D P; China's minimum every day has several ten thousand people to fall ill because of environmental pollution, and the annual cancer patient who causes because of environmental pollution surpasses 1,000,000 people.And middle and small scale coal mine is on average produced 1,000,000 tons of coals, will seize 7 workman's life.
The energy has become the bottleneck of China's economic development now, and it is to make the inflationary main cause of China that energy prices constantly rise.
On the other hand, limited energy resources on the earth force some countries to be supplied as fundamental state policy to guarantee the energy.Do not stint and dispatch troops Iraq for the control bunker Middle East, the world as the U.S..It is increasing that big powers fight for the struggle of resource in the world, and development goes down to cause new world war.The present invention is for thoroughly overcoming the above problems service.
Summary of the invention:
The present invention is according to the conservation of energy and transform law, Carnot's theorem and I study the theory that draws " utilize the physical thermodynamics character of operation material, by heat-pump apparatus, low-temperature heat source can be used as high temperature heat source " for many years; Utilize a series of technology and equipments of the physical thermodynamics character of carbon dioxide and water and my invention, absorb solar radiation, water and be higher than the subzero heat of air more than 10 ℃, produce the steam of HTHP, the pushing turbine generating.And realize carbon dioxide and water, vapour complete alternation generating.Because water, vapour complete alternation generating do not have pollutant outwards to discharge, and in the process of generating, carry out purposes such as heat supply, water supply and confession chilled water, therefore, this power plant is fit to build in the urban area of open water supply.
The specific embodiment:
This technology is provided with two cover endothermic systems.One cover is positioned at the roof.Carbon dioxide in the low pressure CO 2 liquid storage cylinder, be compressed into by compressor in the process of supercritical carbon dioxide liquid, the heat that produces, absorb by the natural water after treatment of heat exchanger (or river, well water, underground water), be sent to the heat accumulation sump after becoming temperature required hot water.
Become low-temperature carbon dioxide supercritical carbon dioxide liquid through heat exchanger, through vaporizer, be ejected into the large tracts of land heat dump that is positioned at the roof, become the carbon dioxide of low-temp low-pressure, be higher than the subzero heat of air more than 10 ℃ in order to absorb solar radiation and temperature.The carbon dioxide that has absorbed heat is back in the low pressure CO 2 liquid storage cylinder, and begins to carry out the circulation of a new round.
The condensed water that absorbs airborne moisture and produce in last heat dump then flows in the condensate collector automatically.
The hot water that produces in heat exchanger all is sent in the heat accumulation sump, and presses the requirement of generating and heat supply, and the hot water in the storehouse is delivered to vacuum circulated water warehouse, and its heat becomes steam and reclaimed by vapour recovery warehouse, is used for generating and heat supply purposes.Lose the chilled water of heat in the vacuum circulated water warehouse, then be sent to freezing sump, in order to provide chilled water to the user.This design can guarantee all permanent generating.
The major part of the steam that vapour recovery warehouse reclaims becomes supercritical liq behind HCS storehouse, supercritical pressure vat, being ejected into expands rapidly on the steam turbine becomes the steam of HTHP, the pushing turbine generating.Low-pressure vapor behind the steam turbine power generation is delivered to vacuum circulated water warehouse by vapor extractor, does not become the steam of water, by the powerful air ejector of power, delivers to vapour recovery warehouse by force, to carry out the circulation of a new round.
The part steam that vapour recovery warehouse reclaims in steam heat-exchanger, is heated into the hot water of HTHP with cold water, to carry out the heat supply purposes.
The steam that vapour recovery warehouse reclaims, the condensate water that in the compression temperature-rise period, produces, from the HCS storehouse to vapour recovery warehouse and the condensate water that produces the steam heat-exchanger together, arrive vacuum circulated water warehouse.Heat becomes steam in vacuum circulated water warehouse, reclaimed to carry out the circulation of a new round by vapour recovery warehouse.
Another set of endothermic system is in water, and natural water behind the treated water that becomes cleaning, flows in the heat dump.Water after heat absorption is sent to the waterworks purposes that supplies water.If the temperature of running water is low excessively, can strengthen the treated right boundary water that becomes clean water and flow into the water yield in the heat dump, because when the caloric receptivity of heat dump was certain, inflow was big more, the temperature of discharge water is just high more.
For supply and the increasing generated energy that increases hot water, then strengthen natural water and flow into the water yield in the heat dump, because under the situation of the natural temperature of equal temperature, the water yield that flows in the heat dump is big more, the heat that absorbs in the heat dump is just big more, and institute's liberated heat is just many more.
