Accompanying drawing 1 is a structural representation of the present invention.
Working principle of the present invention is as follows:
The core-engine of the generation power of being made up of gas engine casing 1, gas compressor 2, firing chamber 3 and compressor wheel 4 is the same with present gas engine, and by the air of gas compressor 2 compressions, burning produces high-temperature high-pressure fuel gas in firing chamber 3.High-temperature high-pressure fuel gas expands at compressor wheel 4 places and does work, and promotes compressor wheel 4 and rotates.And compressor wheel 4 drives gas compressor 2 rotations conversely with pressurized air, keeps normal operation.Also contain a large amount of interior energy by the combustion gas behind the compressor wheel 4.Continue the expansion acting after flowing to power turbine 6 places, energy drives generator 7 rotations by power turbine 6 outputs after changing mechanical energy into by power turbine 6 absorptions.Form with electric energy after generator 7 transforms mechanical energy into electricity is exported.By the combustion gas behind the power turbine 6, also contain certain low thermal energy, use exhaust heat boiler 10 to reclaim.In exhaust heat boiler 10, steam heat-exchanger 11 is at first passed through in combustion gas, and heating heat supply working medium wherein makes it to become saturated vapour.Saturated vapour does work in steam turbine 8, and the rotor rotation in the pushing turbine 8 is rotated generating thereby drive motor 9.Enter high-temperature heat exchanger 16 through after the heat supply working medium condensation of steam turbine 8.In high-temperature heat exchanger 16, heat supply working medium is heated by the cryogen solvent vapo(u)r that produces in the high-pressure generator in the absorption refrigeration unit 27 13, and heat supply working medium is exported after being enhanced temperature, with the form output energy of heat energy.Heat supply recycle pump 12 is used for carrying out the circulation of heat supply working medium.Combustion gas through steam heat-exchanger 11 also has certain heat, enters regenerative heat exchanger 23, to refrigeration working medium thermal regeneration wherein, makes its temperature reach the high pressure boiling point, to concentrate binary refrigeration working medium.
In the present invention by high-pressure generator 13, low pressure generator 14, absorption chamber 15, high-temperature heat exchanger 16, low temperature heat exchanger 17, condensation chamber 18, absorption chamber recycle pump 19, regenerative cycle pump 20, vaporization chamber 21, the absorption refrigeration unit 27 that vaporization chamber recycle pump 22 is formed.The absorption refrigeration unit of forming 27 is a kind of non-compression refrigeration machines that use the double base refrigeration working medium to use thermal pumping, and its working principle is as follows:
The low density refrigeration working medium of absorption chamber 15 outlets delivers into low temperature heat exchanger 17 by regenerative cycle pump 20.In low temperature heat exchanger 17, the low density refrigeration working medium absorbs the heat by the high concentration refrigeration working medium of low pressure generator 17 outputs, enters the refrigeration working medium regenerative heat exchanger 23 in the exhaust heat boiler 10 then.Refrigeration working medium in regenerative heat exchanger 23 is heated to the high-boiling temperature.Refrigeration working medium with high-boiling temperature enters high-pressure generator 13.In high-pressure generator 13, the refrigeration working medium boiling produces the cryogen solvent vapo(u)r, and the concentration of refrigeration working medium is raise.The refrigeration working medium that is come out by high-pressure generator 13 bottoms enters low pressure generator 17 after high-temperature heat exchanger 16 coolings, heated by the cryogen solvent vapo(u)r from high-pressure generator 13 tops in the pipe, boiling produces the cryogen solvent vapo(u)r once more, and the concentration of refrigeration working medium further improves.
The cryogen solvent vapo(u)r that produces in the high-pressure generator 13 is by the line transportation on high-pressure generator 13 tops, in low pressure generator 17 with low pressure generator 17 in refrigeration working medium carry out emitting latent heat after the heat exchange, condense into the cryogen solvent, after throttling, enter condensation chamber 18.The cryogen solvent vapo(u)r of evaporation also enters condensation chamber 18 in the low pressure generator 17.Be cooled water quench in the water coiler 24 and become the cryogen solvent of cryogen solvent vapo(u)r in condensation chamber 18.The cryogen solvent enters behind throttling arrangement in the solvent dish of vaporization chamber 21, and by 22 conveyings of vaporization chamber recycle pump, the heat of freezing heat-transfer working mediums in freezing heat-transfer working medium coil pipe 26 outer surfaces of spray in vaporization chamber 21, absorption refrigerating heat-transfer working medium coil pipe 26 and vaporize and become the cryogen solvent vapo(u)r.Freezing heat-transfer working medium temperature reduces, and exports cooling power, reaches the purpose of refrigeration.
On the other hand, the high concentration refrigeration working medium that is come out by low pressure generator 14 enters absorption chamber 15 after low temperature heat exchanger 17 reduces temperature, mix the back with absorption chamber 15 original low density refrigeration working mediums by on 19 conveyings of absorption chamber recycle pump and the cooling water serpentuator 25 of spray in absorption chamber 15, circularly cooling working medium is absorbed in the cryogen solvent vapo(u)r that produces in the vaporization chamber 21, make vaporization chamber 21 keep required low pressure, the cryogen solvent is able to constantly vaporization heat absorption.Concentration reduced after the refrigeration working medium of spray absorbed the cryogen solvent vapo(u)r, became the low density refrigeration working medium again, was carried by generator recycle pump 20 again, through behind the low temperature heat exchanger 17, was sent to the refrigeration working medium regenerative heat exchanger 23 in exhaust heat boiler 10.The heat that absorption process produces is then taken away by the cooling water in the cooling water serpentuator 25 in the absorption chamber 15.
The present invention uses gas engine to do power source, absorb back drive generator by the row combustion gas by power turbine and obtain the output of part electric energy, contain the combustion gas that has surplus heat and in exhaust heat boiler, produce the rotation of steam pushing turbine by the heating heat supply working medium, thereby the drive generator for electricity generation, output another part electric energy.And the mode pumping heat that uses waste heat combustion gas thermal regeneration double base refrigeration working medium in exhaust heat boiler obtains refrigeration output to produce the refrigeration cold junction.Obtain heat supply output with the hot junction heating heat supply working medium that freezes, realize electric, hot, the cold output of uniting, make full use of the output energy of gas engine, to satisfy the composite demand of energy.
Core-engine of the present invention and power turbine association can use homemade YD-3(SK), also can use similar unit, exhaust heat boiler 10 can directly adopt at YD-3(SK) method that adds tube coil type heat exchanger in the air outlet flue realizes.The common low-pressure turbine that steam turbine 8 can use the power station to use.Generator 7 and 9 can use common synchronous alternator group, also can use as the full speed rare-earth synchronous motor of number of patent application as CN 91101413.6, uses converter technique, can not control the rotating speed of power turbine 6 and steam turbine 8.Such device will have the electric energy output of about 3.5MW, the cooling power output of 4.5MW and the heat supply energy output of 2MW.
When using common building thing air-conditioning among the present invention, the double base refrigeration working medium of absorption refrigeration can use lithium bromide and water, and it requires lower to refrigeration plant manufacturing (as sealing), when being used for natural gas liquefaction, also water and ammonia can be made, lower cryogenic temperature can be obtained.Heat supply working medium can make the water heat absorbing type cooling machine set 24 can be with reference to the design of common Absorption Refrigerator, the present invention except that the size that can reduce high-pressure generator 14, with common Absorption Refrigerator require identical.
