Description
Technical field
The present invention relates to a kind of power generation system, particularly a kind of power generation system of utilizing low-temperature heat source or higher environment heat resource power generation.
Background technique
The steam power generating efficiency of prior art is generally not high, generally all below 40%, some devices that utilize low-temperature heat source or environment thermal source to generate electricity have also appearred at present, it mainly is to utilize lower boiling working medium gasification back to promote steam turbine power generation, because technical incomplete maturation, efficient is lower, causes the heat more than 50% all to fail to be fully used.
Summary of the invention
Purpose of the present invention just is to provide a kind of low-temperature heat source or environment thermal source heat, power generation system that generating efficiency is high of making full use of.
The technological scheme of being taked is as follows to achieve the above object of the invention:
A kind of power generation system of utilizing low-temperature heat source or environment heat resource power generation, it includes acting unit and heat pump cycle unit, the acting unit is the loop of mainly being made up of vaporizer 1, steam turbine 3, condenser 5 and the preheater 7 of the connection of order head and the tail, and the acting working medium in the loop is low boiling working fluid; The heat pump cycle unit pack contains heat absorber 9 and compressor 10, and wherein the inlet of heat absorber 9 is communicated with the condenser 5 of acting unit, the outlet of compressor 10 is communicated with the preheater 7 of acting unit, and preheater 7 is communicated with condenser 5 by throttle valve 8.
Above-mentionedly also duct thermostat 14 can be set by vaporizer to the pipeline of steam turbine, duct thermostat is furnished with high temperature heat source.The temperature fluctuation of low-temperature heat source or environment thermal source is bigger, may influence the smooth running of system, this is that the high temperature heat source that can start combustion gas, fuel oil or coal-fired heating heats working medium in the loop, to eliminate the adverse effect that low-temperature heat source or variation of ambient temperature are brought.
Above-mentioned steam turbine 3 also can be furnished with water condensation bypass 2.Weary gas is carried out condensation when above-mentioned water condensation bypass 2 can be broken down in the heat pump cycle unit or overhaul temporarily, move continuously to guarantee the normal of system, or use as the simple cycle condensation device.
Beneficial effect of the present invention is the weary gas that its working medium of utilizing the heat pump cycle unit goes condensation to be discharged by steam turbine 3, the weary gas heat reuse that then utilizes the heat pump cycle unit to absorb again, go to heat the acting working medium in the preheater, this with steam generating system in the past in heat of condensation directly discharge the external world and compare and can improve generating efficiency greatly, capacity usage ratio can reach about 85%, and used low-temperature heat source does not need to consume non-renewable resources such as fire coal, fuel oil, when saving the energy, also have the effect of environmental protection, meet the needs of building a conservation-minded society.
The invention will be further described below in conjunction with accompanying drawing:
Description of drawings
Figure is a structural representation of the present invention
Embodiment
Present embodiment is a thermal source with the low-temperature heat source with 130 ℃-230 ℃, and its acting working medium can be selected perfluor ethyl methyl ether, fluorine methyl propyl ether, perfluor Propylene Glycol Dimethyl Ether, perfluoro acetone, perfluoropropane etc. for use.Heat pump cycle unit heat pump fluid can be middle high temperature freon, fluorine ether, methyl alcohol etc.
The loop that vaporizer 1, steam turbine 3, condenser 5 and the preheater 7 that the acting unit is mainly connected by the order head and the tail formed, the heat pump cycle unit pack contains heat absorber 9 and compressor 10, wherein the inlet of heat absorber 9 is communicated with the condenser 5 of acting unit, the outlet of compressor 10 is communicated with the preheater 7 of acting unit, and preheater 7 is communicated with condenser 5 by throttle valve 8.
Heat medium by low-temperature heat source 17, earlier to the heating of the perfluoropropane in the vaporizer 1 vaporization, and make it to be warming up between 130 ℃-230 ℃, after pressure increases to 8-15MP, enter steam turbine 3 expansion actings by duct thermostat 14 again, steam turbine 3 drives generator 4 generatings, become weary gas after the acting of perfluoropropane gas and enter condenser 5, under 40-60 ℃ temperature, liquefy, this condenser 5 carries out heat exchange as the thermal source of heat pump cycle simultaneously, heat pump fluid becomes the wet vapor that is mixed with small amount of liquid after this heat absorption, entering heat absorber 9 further draws by in the vaporizer 1 and come the waste heat of low-temperature heat source, becoming has overheated saturated vapour slightly, enters heat pump compressor 10 superchargings and heats up.The low temperature perfluoropropane liquid that comes out from condenser 5 is delivered to preheater 7 through suction booster 6 and is tentatively heated up, and enters vaporizer 1 again and finishes the acting circulation, and suction booster 6 can be selected the digital control type suction booster for use, and its Control Parameter is adjusted according to actual conditions immediately by master-control room.The heat pump fluid gas that comes out from compressor 10 passes to perfluoropropane with heat at preheater 7, and the liquefaction of self lowering the temperature becomes overcooled liquid, enters condenser 5 by shutoff valve 8 again and finishes heat pump cycle.System's start of run, compressor 10 can drive running by motor 6, and after system ran well, the power of compressor 10 can be provided by steam turbine by coupling 11.
If when heat source temperature is low, but then 14 pairs of working medium of flowing through of start-up temperature regulator heat again, to guarantee the proper functioning of system.
For 80-130 ℃ thermal source, acting working medium can be selected pentafluoroethane or E125 for use, acting pressure 6-10MP, and condensing temperature is 25-65 ℃.
For 25-80 ℃ from underground heat, the cryogenic conditions solar energy heating, the hot air in rivers,lakes and seas, desert, light industry and the high slightly thermal source of life used heat geometric ratio ambient temperature, can compile the back so that large-scale utilization, the acting working medium of selecting for use can be sulphur hexafluoride, perfluor dimethyl ether, hexafluoroethane, about acting pressure 6-9MP, because this type of working medium critical temperature is low, pressure is higher, should be controlled at the following 2-4 of critical temperature ℃ to the working medium liquid storage, to guarantee security of operation.
The present invention can realize simple cycle when opening condensation bypass 2, at normal temperatures weary gas is carried out condensation, satisfy the production under the extensive condition of some producer, but efficient can be reduced to about 55%.
