Abstract
The utility model discloses a waste heat recovery type distributed energy and underground water source heat pump coupling system. Natural gas is burned by a gas engine to drive a generator; the generator generates power to drive a underground water source heat pump; meanwhile, smoke produced by the gas engine enters a waste heat boiler; the smoke and steam discharged by the waste heat boiler are absorbed by a condensing heat exchanger and an absorption heat pump respectively; heat discharged by the condensing heat exchanger is input into the absorption heat pump so as to provide another part of heat; in a waste heat recovery process, waste heat of the smoke discharged by the condensing heat exchanger accounts for 10 percent of the heat produced by burning of all the natural gas, and the part of heat is displaced into underground water in an underground water source heat pump system through a steam-water heat exchanger, so that at least 9 percent of waste heat can be recovered, the temperature of the supplied underground water can be increased by 2 DEG C, the defect of over-low temperature of the underground water can be overcome, and meanwhile, the efficiency of the heat pump can be increased by about 6 percent again by the increase in temperature of the underground water.
Description
Technical field
The utility model relates to distributed energy and water resource heat pump coupled system, especially a kind of afterheat recovery type distributed energy and groundwater heat pump coupled system.
Background technology
Be accompanied by the increase of electricity needs and the aggravation of world energy sources crisis, readjust the energy structure, improve energy utilization rate, improve energy security, the solution environmental pollution is own through becoming the emphasis of China's energy strategy.Distributed energy resource system is a kind of multiple-supplying supply system that is based upon on the cascaded utilization of energy ideal basis, by at Demand-side according to the different demands of user to the energy, realize the energy supply pattern of " temperature counterpart, cascade utilization ", the loss of conveying process is down to minimum, thereby realize the maximization of efficiency of energy utilization and environmental benefit.The Distribution of Natural formula energy is to utilize natural gas to be fuel, and after the combustion machine generated electricity by gas-firing, the high-temperature flue gas of generation was sent into waste heat utilization equipment, can be used for heating winter, can be used for cooling summer, but productive life hot water also, and driving the shortage of heat part can be supplied by the combustion gas of afterburning.Thereby realize the cascade utilization to the energy, can improve efficiency of energy utilization to 80%-90%.That but this conventional distributed energy resource system exists is single, energy utilization rate promotes the problems such as limited, economic not good enough.Therefore produced gradually new distributed energy coupled system, it is based on conventional distributed energy technology be coupled environment, regenerative resource, conventional energy resource system, novel regional complex ENERGY PLANNING, intelligent grid and intelligence communication control technology etc., consisted of a kind of new distribution type energy resource system, but still the situation that exists a part directly to discharge with the flue gas waste gas of low-grade energy.Pollute environment, wasted energy.
Summary of the invention
The utility model is the coupling of afterheat recovery type distributed energy and groundwater heat pumps, solved the energy waste problem that still causes with the direct discharging of the flue gas waste gas of heat after the waste heat recovery, improved the efficient of using energy source.
The utility model is to overcome the technical scheme that its technical problem adopts to be, a kind of afterheat recovery type distributed energy and groundwater heat pump coupled system, comprise afterheat recovery type distributed energy subsystem, groundwater heat pump subsystem, wherein afterheat recovery type distributed energy subsystem comprises: gas engine, generator, waste heat boiler, condensing heat exchanger, absorption heat pump; The groundwater heat pump subsystem comprises: groundwater heat pump, vapor-water heat exchanger; The gas engine gas-firing drives generator, and the generator generating drives groundwater heat pump and carries out heat supply; The flue gas of gas engine generation simultaneously enters into waste heat boiler, and condensing heat exchanger and absorption heat pump absorb respectively flue gas and the high-temperature steam that waste heat boiler gives off, and condensing heat exchanger is emitted heat as the low-temperature heat source of absorption heat pump; The flue tail gas of discharging after the condensing heat exchanger heat exchange enters into vapor-water heat exchanger, and vapor-water heat exchanger is replaced the heat in flue gas in the underground water that enters the groundwater heat pump evaporator end.
In said system, condensing heat exchanger gives off all natural gas firing that fume afterheat accounts for and produces 10% of heat, by vapor-water heat exchanger, this part heat is replaced in underground water in groundwater heat pumps, can reclaim at least 9% waste heat, can make the temperature of groundwater supply improve 2 ℃, the deficiency that the recharge of groundwater temperature is too low, the simultaneously raising of ground water temperature can improve heat pump efficiency 6% left and right again.
Coupling by afterheat recovery type distributed energy and groundwater heat pump, realize that the system capacity step takes full advantage of, according to the performance of heat pump (Energy Efficiency Ratio be 4.0 consider), 40% electric power that gas engine sends can produce heat or the cold more than 160%, more than 40%, the final primary energy comprehensive utilization ratio of the coupled system of afterheat recovery type distributed energy and groundwater heat pump can reach more than 200% in conjunction with the primary energy comprehensive utilization ratio of residual neat recovering system.Native system can also make the electric energy of online difficulty be fully used, and heats by groundwater heat pump, and the benefit of the Distribution of Natural formula energy is further promoted, and promotes the benign development of industry.
The beneficial effects of the utility model are: native system realized the taking full advantage of of NG Distributed Energy System fume afterheat, and improved the water inlet water temperature of groundwater heat pump subsystem evaporator end, improved entire system efficient.
