Description of drawings
Fig. 1 is multi-functional distributed triple-generation first embodiment of system of the present invention;
Fig. 2 is multi-functional distributed triple-generation second embodiment of system of the present invention.
Embodiment
The present invention proposes two kinds of concrete technological schemes, these two kinds of technological schemes all have characteristics set forth above.Scheme 1 is gas turbine and the absorption unit distributed triple-generation of residual heat type system, and scheme 2 is gas turbine and the absorption unit distributed triple-generation of steam type system, will be elaborated to these two kinds of schemes below.
The system body of scheme 2 and scheme 1 are basic identical, and warm exhaust heat boiler and steam type lithium bromide double effect absorption unit replaced the gas-type lithium bromide absorption-type machine unit during difference was to use.Identical with scheme 1, this scheme also can be divided into two kinds of methods of operation.Under cooling condition, fuel enters gas turbine power generation, and warm exhaust heat boiler was produced steam during the turbine exhaust at first entered.Steam can be assigned in the double-effect lithium bromide absorption type unit of many parallel connections by the female pipe of steam and freeze, the heat extraction of adopting the method identical with scheme 1 to reclaim absorption unit condenser simultaneously.In the smoke evacuation of warm exhaust heat boiler enter the low temperature exhaust heat boiler, produce the hot water that drives 95 ℃ in absorbed moisture removing device.The effect of compression-type refrigeration unit is with scheme 1.When under heating condition, moving, the steam driven double-effect lithium bromide absorption type unit heat supply that middle temperature exhaust heat boiler produces, remaining part is identical with scheme 1.
More than the concrete thinking of two schemes aspect cascaded utilization of energy be: the heat of high temperature section flue gas be used for the generating; The middle-temperature section heat drives heat pump in the winter time the time, the heat that extracts more low temperature from renewable energy sources or municipal middle water resource is used for heat supply, energy utilizes level to be higher than the direct heating mode of conventional cool and thermal power system, and that the heat of middle-temperature section is used to drive absorption unit refrigeration summer is as broad as long with usual manner; The low-temperature zone heat directly satisfies general hot and the dehumidifying demand used, and reduces exhaust temperature as far as possible, and temperature of exhaust fume is reduced to about 100 ℃, reduces emission loss and environmental pollution.System does not have afterburning under nominal situation, not enough refrigerating capacity is provided by compression-type refrigeration and cold accumulator, but still keeps absorption refrigeration to account for the principal status of public economy of cooling load.Compression type unit and cold accumulator are finished the function of regulating the cold ratio of cool and thermal power system electricity together.Renewable energy sources and water resources and cogeneration cooling heating system complementation are unexistent in the present other system in the scheme.Two schemes that the present invention proposes have all considered to use solar energy, geothermal power and middle water resources in cogeneration cooling heating system.As everyone knows, with the weakening of radiation intensity, heat-collecting temperature sharply descends solar energy in the winter time, and this is the difficult point that solar energy utilizes in the winter time.In summer, the high-temperature water that solar energy produces participates in absorbed moisture removing, and low temperature water is used to supply the domestic hot-water; In the winter time, solar energy can be realized the stable operation in two seasons of summer in solar thermal utilization winter as the part (about 25 ℃) of double effect absorption type heat pump low-temperature heat source.Utilize geotemperature with the little characteristics of variation of ambient temperature, as the cooling water of system's refrigerator, then can be used as the low-temperature heat source of system's heat pump unit with surface water or phreatic water winter summer.Greatly reduce the consumption of cooling water with the cooling water of municipal middle water as cooling machine set summer in the scheme, even need not cooling tower, thereby produce good economic benefit and view benefit.Water is with solar water, underground heat etc. in can utilizing winter, as the low-temperature heat source of absorption heat pump, and also can be through after the temperature raising of compression type unit, indirectly as the absorption heat pump low-temperature heat source.There is a large amount of low temperature hot types to go into environment in the absorption unit condenser, through studies show that wherein nearly 10% heat can reclaim, and is used for productive life hot water.Specific practice is that heat exchanger of addition is used for productive life hot water before condenser, and this method has tangible energy-saving benefit with respect to present method with gas fired boiler or electric heating productive life hot water.The heat temperature of residue 90% can be considered to combine with the function of building about 40 ℃ in the condenser.For example can combine with the natatorium, natatorium Chi Shui will maintain 25 ℃ usually, the low temperature heat extraction of condenser is enough to heat swimming pool water, so not only saved conventional enormous expenditure with natural gas boiler or electric heating Chi Shui, also make absorption unit condenser working condition be improved, having improved the efficiency of energy utilization of absorption unit, is to kill two birds with one stone, and very remarkable energy saving effect is arranged.
