Abstract

The utility model discloses a waste heat recovery type distributed energy and sewage source heat pump coupling system. Natural gas is burned by a gas engine to drive a generator; the generator generates power to drive a sewage source heat pump to produce a part of heat; 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 a sewage 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 sewage in the sewage source heat pump can be increased by 2 DEG C, and meanwhile, the efficiency of the heat pump can be increased by about 6 percent again by the increase in temperature of the sewage.

Description

Afterheat recovery type distributed energy and sewage source heat pump coupled system
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 sewage source 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 with afterheat recovery type distributed energy and sewage source heat pump system coupling, solved the energy waste problem that still causes with the direct discharging of the flue gas of heat after the waste heat recovery, effectively again utilized simultaneously sewage resource, solve the too low problem of sewage temperature in the sewage source heat pump in winter, improved the efficient of using energy source.
The utility model is to overcome the technical scheme that its technical problem adopts to be, whole coupled system comprises afterheat recovery type distributed energy subsystem, sewage source heat pump subsystem, and wherein afterheat recovery type distributed energy subsystem comprises: gas engine, generator, waste heat boiler, condensing heat exchanger, absorption heat pump; The sewage source heat pump subsystem comprises: sewage source heat pump, vapor-water heat exchanger; The gas engine gas-firing drives generator, and the generator generating drives sewage source 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 input absorption heat pump; The flue gas of discharging after the condensing heat exchanger heat exchange enters into vapor-water heat exchanger by the flue tail gas pipeline, and vapor-water heat exchanger is replaced the heat in flue gas in the sewage that enters sewage source heat pump.
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 sewage source heat pump system, can reclaim at least 9% waste heat, can make the temperature of sewage improve 2 ℃, replenish the too low deficiency of sewage temperature, the raising of sewage water temperature simultaneously can improve heat pump efficiency 6% left and right again.
Coupling by afterheat recovery type distributed energy and sewage source 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 afterheat recovery type distributed energy and sewage source heat pump coupled system 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 the benefit of the Distribution of Natural formula energy is further promoted, and promotes the benign development of industry, by again utilizing the energy in sewage, the energy that originally runs off is utilized, and has saved resource.
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 in the sewage source heat pump system, thereby improved entire system efficient.
