Technical field
The utility model belongs to the heat supply process field, particularly utilizes the system of steam boiler and steam-powered water source heat pump combining heat supply.
Background technology
Water source heat pump technology is the principle according to Carnot cycle, by importing a part of high-grade energy, utilizes the various reproducible low-grade energies of occurring in nature that heating, refrigeration and domestic hot-water's technology is provided for building.The high-grade energy that water source heat pump technology need be imported is mainly electric energy, and its utilizable various reproducible low-grade energy comprises: the shallow-layer ground energy in the underground, the low grade heat energy in low grade heat energy, municipal sewage and the industrial wastewater in the rivers,lakes and seas, various industrial exhaust heats or the like.
Need consumed power when utilizing water source heat pump technology to carry out heat supply, because the generating efficiency of power plant generally has only about 30% at present, add the loss of power transmission and transformation, the user side power consumption efficiency has only about 25%, that is to say that the user uses a electric energy, power plant will consume four parts primary energy, so the fractional energy savings of electrically driven (operated) heat pump is not high generally.
Existing heat-supplying mode generally is to carry out heat supply with direct heat hot water of boiler or steam.Because the efficient of boiler is generally between 70-85%, so consume the heat energy that a primary energy can only obtain 0.7-0.85 part.
Summary of the invention
The purpose of this utility model is for overcoming the weak point of prior art, a kind of system that utilizes steam boiler and steam-powered water source heat pump combining heat supply is proposed, energy in the utility model system in the steam is not only discharged in vain, but also has obtained a large amount of energy from the external world by heat pump.
The system that utilizes steam boiler and steam-powered water source heat pump combining heat supply that the utility model proposes, it is characterized in that, this system mainly comprises: steam boiler, steam turbine, water resource heat pump and heat exchanger, its annexation is: the outlet of steam boiler links to each other with the inlet of steam turbine, and the outlet of steam turbine links to each other with the heat of heat exchanger inlet; The heat outlet of heat exchanger links to each other with the inlet of steam boiler, the backwater of heating network links to each other with the heat of water resource heat pump inlet (31), the heat outlet (32) of water resource heat pump connects with the cold inlet of heat exchanger, the cold outlet of heat exchanger links to each other with the water supply of heating network, and the backwater that supplies of low level heat energy links to each other with cold outlet (34) with the cold inlet (33) of water resource heat pump respectively; The shaft joint that steam turbine has by himself links to each other with water resource heat pump.
Technical characterstic of the present utility model and beneficial effect:
The utility model directly drives heat pump with the steam that steam boiler produces, for example obtain various reproducible low-grade energies from the outside: the shallow-layer ground energy the underground, the low grade heat energy in low grade heat energy, municipal sewage and the industrial wastewater in the rivers,lakes and seas, various industrial exhaust heats or the like, still contain lot of energy in the steam after the recirculated water driving water resource heat pump that utilizes these low-grade energies to heat heating networks does work, utilize these energy to heat the recirculated water of heating network once more, get back in the boiler and these steam become condensed water at last by heat exchanger.In this course, part energy in the steam is used for obtaining from the outside reproducible low-grade energy, another part is used for directly heating circulation water for heating, and the energy in the steam is not only discharged in vain, but also has obtained a large amount of energy from the external world by heat pump.
Description of drawings
Fig. 1 is that the system of steam boiler of the present utility model and steam-powered water source heat pump combining heat supply constitutes and the workflow schematic diagram.
The specific embodiment
The utility model proposes the system and method for a kind of steam boiler and steam-powered water source heat pump combining heat supply, reach embodiment in conjunction with the accompanying drawings and be described in detail as follows:
Structure of the present utility model as shown in Figure 1, this system mainly comprises: steam boiler 1, steam turbine 2, water resource heat pump 3, heat exchanger 4, its annexation is: the outlet of steam boiler 1 links to each other with the inlet 21 of steam turbine 2, and the outlet of steam turbine 2 links to each other with the heat inlet 41 of heat exchanger 4; The heat of heat exchanger 4 outlet 42 links to each other with the inlet of steam boiler 1, the backwater 6 of heating network links to each other with the heat of water resource heat pump 3 inlet 31, the heat of water resource heat pump 3 outlet 32 links to each other with the cold inlet 43 of heat exchanger 4, the cold outlet 44 of heat exchanger 4 links to each other with the water supply 5 of heating network, and the backwater that supplies of low level heat energy 7 links to each other with cold outlet 34 with the cold inlet 33 of water resource heat pump 3 respectively.The kinematic axis of steam turbine 2 links to each other with the kinematic axis of compressor in the source pump by (himself has) shaft joint, and like this, rotatablely moving of steam turbine can drive rotatablely moving of compressor, thereby drives source pump 3 work.
The course of work of the present utility model is: as shown in Figure 1, the steam that boiler 1 produces enters steam turbine 2, drive water resource heat pump 3 earlier, obtain recirculated water in the heat energy heating heating network in the low level heat energy by water resource heat pump 3, still contain a large amount of heat energy behind the steam drive water resource heat pump 3, heat recirculated water in the heating network once more by heat exchanger 4, like this, recirculated water in the heating network through heat exchanger 4 heating, enters heating network to user's heat supply more at last earlier through water resource heat pump 3 heating.Because the efficient of boiler is generally 75-85%, the efficient of steam turbine is generally 16-30%, and the Energy Efficiency Ratio of water resource heat pump is 4.5-5.0 (consumes a high-grade energy, can obtain the heat energy of 4-5 part).So, according to above technical indicator measuring and calculating, consume a primary energy, the heat energy maximum that is used for heat supply that finally obtains can be 0.85 * 0.3 * 5.0+0.85 * 0.7=187%, and the boiler of same efficiency adopts the heating efficiency of traditional heat-supplying mode only is 85%; Minimum also can reach: 0.75 * 0.16 * 4.5+0.75 * 0.84=117%, it only is 75% that the boiler of same efficiency adopts the heating efficiency of traditional heat-supplying mode.The utility model can improve utilization efficiency of energy greatly.
