Embodiment

Embodiment 1

Present embodiment is applicable to that inflammable or harmful working medium efficiently does work, and can change its ultrahigh pressure into medium pressure gas, and don't loss potential; The entering medium pressure turbine is done manual work; Alleviate the requirement of steam turbine operation operating conditions and reveal the extent of injury, and the corresponding exhaust steam flow that has reduced the entering condenser, thereby the heat of condensation discharging reduced; Significantly improve circuit efficient, working medium can be selected second propane, isobutane, R161, R152, R143, R254, dimethyl ether, 2-fluoro-propane for use.

Existing is that example is explained with the 2-fluoro-propane.

150-250 degree centigrade the thermal source that comes by 17, the 2-fluoro-propane in the reheat heat exchanger makes on working medium 2-fluoro-propane temperature to the 150-250 degree; Pressure 10-22MP gets into jet-stream whirl formula compressor pump 16, the low-pressure gas of compression from about the 0.3-0.8MP of turbulence pump 8; Boost to about 3MP, get into pump 8 through diverter valve 20 fractions and remove to compress the weary gas that comes out from steam turbine, rise to about 0.3-0.8MP; Most of heat exchanger 5 that gets into is heated 6 actings of back entering steam turbine by the waste heat of heat exchanger 1; Weary gas after the acting, wherein a part is by pump 16 back pressure, and residue another part then gets into condenser 9 by cold accumulating pond 21 or other refrigerant cold energy institute condensations; Deliver to storage tank 11 through feed back pump 10, deliver to by high-pressure metering pump 12 again and deliver to heat exchanger 1 after heat exchanger 13 preheatings and accomplish circulation.

Embodiment 2

This instance is that available carbon dioxide is a working medium according to cement plant or the useless waste heat situation design of sintering plant higher temperature.

The useless waste heat that comes from the cement plant sintering plant makes the carbon dioxide the heat exchanger 1 rise to the 300-400 degree, and pressure 15-35 MPa gets into steam turbine 2 actings; Weary temperature degree is reduced to 30 deg.c, through heat exchanger 3, draws the waste gas residual heat that comes from heat exchanger; And rise to 4 actings of 200-300 degree centigrade of entering steam turbine, and the exhaust steam outlet temperature is reduced to-20 degree and is got into condenser 9, and the heat absorption back gets into heat exchanger 5; Absorption rises to the 100-200 degree from the useless waste heat supply temperature of heat exchanger 3; Get into low-pressure turbine 6 actings, weary temperature degree can be reduced to-50 deg.c, and above-mentioned weary gas can be used as the low-temperature receiver use and also can directly be compressed by jet-stream whirl formula compressor pump 8; Temperature and pressure all improve a lot, thereby obtain liquefaction through air cooling device 26 and cold accumulating pond 21.Low temperature gas-liquid mixture by heat pump circulating device throttle valve 14; In the time of can guaranteeing that cold accumulating pond 21 is incompetent; Carbon dioxide is liquefied at subzero 20 degrees centigrade; And rise to 32 deg.c through heat pump cycle compressor 15, heat is fed back to carbon dioxide liquid, and heat pump fluid obtains Hui Leng simultaneously in heat exchanger 13; More help in condenser 9, discharging cold energy, the carbon dioxide after the liquefaction is delivered to storage tank 11 through feed back pump 10 and is arrived heat exchanger 1 completion major cycle through high-pressure metering pump 12, heat exchanger 13.Another bypass carbon dioxide liquid is delivered to heat exchanger 19 by high-pressure metering pump 18 after storage tank 11 absorptions are boosted; Still can make it reach the supercritical state about temperature 50-80 degree centigrade, pressure 10-18 MPa by the useless waste heat of heat exchanger 5; Get into the low-temp low-pressure weary gas of jet pump 8 compressions, get into condenser 9 with elevated pressures after the mixed flow and together accomplish condensation process from steam turbine 6.The cold energy condition permission of air cooling device, cold accumulating pond should do one's best and get into condenser 9, and this can significantly reduce condensing pressure, reduces compression power consumption and improves conversion efficiency.For preventing that the high-pressure carbon dioxide liquid condensation from being dry ice, can add anticoagulant, anticoagulant can be selected one or more in methyl formate, acetone, the propene carbonate for use.
