Technical field
The present invention relates to low-temperature cogeneration fields, more particularly to one kind to be based on the high magnetic conduction stream of carbon dioxide-base nanometer mixed phase
The low-temperature waste heat power generation system of body；Big industry such as cement, steel, thermoelectricity, ceramics and coloured are discharged more particularly to industrial waste heat
The low taste heat resource power generation in the fields such as metal, also including the use of generations of electricity by new energy such as solar energy, geothermal energy and sea water heat energies.
Background technique
Currently, the generation mode of mainstream is the thermoelectricity based on the fossil fuels such as coal and natural gas, but fossil fuel conduct
A kind of non-regeneration energy has one day exhausted eventually.Currently, a kind of very promising scheme is sent out using low-grade heat source
Electricity.Industrial waste heat discharges big industry such as cement, steel, thermoelectricity, ceramics and non-ferrous metal etc., these industries not still waste heat
Rich and influential family is discharged, and is also the main industries of room temperature air discharge.
The basic reason of China's Energy situation sternness at present is that energy consumption efficiency is low.The output of China's standard coal per ton is imitated
Rate just corresponds to the 28.6% of the 10.3% of the Japan, U.S..Nearly 60~65% energy conversion is waste heat money in China's energy consumption of industry
Source.The most country of UTILIZATION OF VESIDUAL HEAT IN is the U.S. at present, and for its utilization rate up to 60%, European utilization rate is 50%, we are national only
Have 30%.With regard to waste heat (waste heat) using status from the point of view of, China utilizes space there are also very big.350 DEG C of domestic industry enterprise at present
Low temperature exhaust heat below accounts for 60% or more of waste heat total amount, because its utility value is lower, recovery technology relatively fall behind, the rate of recovery and
Recovery value is low, and invests retirement period long (6~7 years) and abandoned by most enterprises.
The highly energy-consumings industry development such as cement, steel and the ceramics in China is rapid, has driven the quick of high, middle temperature cogeneration
Development, has formd more complete industry, but low-temperature cogeneration has then just started.As the worldwide energy is tight
It lacks, various countries are committed to energy conservation and emission reduction, strive sustainably developing.Such a fact based on energy shortages, more than low temperature
The problem of heat utilization, each state was all in the investment and research for reinforcing this respect at more and more important energy striving direction, it is desirable to
Obtain bigger and more incomes.

Power generation of the organic working medium (such as R123, R245fa, R152a, chloroethanes, propane, normal butane and iso-butane) as cycle fluid
System generates higher pressure since organic working medium can gasify at a lower temperature, pushes turbine (turbine) acting,
Therefore organic working medium cycle power generation system can be at 200 DEG C of flue-gas temperature or so, water temperature has utility value in 80 DEG C or so realizations
Power generation.This technology is exactly more advanced application technology in developed country, and the enterprise that China has in recent years is absorbed by introducing,
Also this technology has been grasped, has also had more outstanding product at home and abroad to apply.
2, Stirling thermomotor cycle generating system
Stirling thermomotor cycle generating system is the waste heat recovery plant using low-temperature cogeneration, can be recycled 100 DEG C
To 300 DEG C of waste heat, 20% generating efficiency can be reached.From the point of view of data, generating efficiency is better than the Low Temperature Steam of existing market
The generating efficiency of cycle generating system and organic working medium electricity generation system, system generating efficiency under the conditions of 100 DEG C of waste heat reach
7.3%, generating efficiency is up to generating efficiency under conditions of 13.7%, 200 DEG C up under conditions of 18.4%, 250 DEG C under conditions of 150 DEG C
Generating efficiency is up to generating efficiency under conditions of 22.1%, 300 DEG C up to 25.0%.It can reach in this way under the conditions of such temperature of waste heat
Generating efficiency be at present it can be seen that best level, reached the advanced technology water that electric energy is converted into from low temperature heat energy
It is flat.In low temperature to moderate temperature (100~300 DEG C) range, Stirling engine be by the development of evil in febrile disease of low level thermal energy at mechanical or
The optimal selection of electric power.

Supercritical carbon dioxide electricity generation system is the working medium that supercritical carbon dioxide liquid is rankine cycle system, with dioxy
Change the newest cogeneration technology that carbon turbine specific turbine is core technology.This electricity generation system has wider in terms of cogeneration
General application advantage, all technical be better than water vapour wave agree the circulatory system and current state-of-the-art organic wave is agreed
The circulatory system especially has apparent advantage in terms of generating efficiency and equipment volume.Supercritical carbon dioxide heat engine is one
Kind platform technology, efficiency is up to 30%.Application range include gas turbine, fixed dynamic power unit, industrial waste heat recycling,
The recycling heat energy of solar heat, underground heat and mixing internal combustion engine etc..Currently, it is limited due to being machined with the technology of sealing etc.
System, China is in terms of supercritical carbon dioxide turbine circulating generation also in test development phase.
