Description
Technical field
It the utility model is related to the heating system of a kind of heat pump and power plant cycle water coincidence.
Background technology
Current, China's town dweller's winter heating is concentrated mainly using cogeneration units as origin of heat with big pipe network
It is supplied as principal mode.Cogeneration of heat and power central heating pattern is although the pure condensate generating set heat utilization rate that compares is higher, power supply
Coal consumption is relatively low, but two problems are primarily present in terms of system energy consumption：One is draw gas heat and the actual heating heat of resident
Between quality discrepancy it is larger；The second is there is certain heat loss in hot pipe network.
For large-scale thermoelectricity unit because heating area is very big, heat supply coolant-temperature gage is higher, one-level heat exchange station leaving water temperature one
As at 120~130 DEG C, this causes extracted steam from turbine parameter also higher, and general heating extraction pressure is 0.35~0.55MPa.So
And if resident uses common radiator heating, take around 60~70 DEG C of hot water；If using floor heating or fan-coil heating,
Then 40~50 DEG C of cans of water temperature meet heating demand, and this heat energy quality discrepancy that draws gas with power plant is very big, thus part power plant or
Person can increase heat supply using the high-grade heat energy to draw gas using absorption heat pump by suitably reducing the temperature of outer supplying hot water
Amount or the amount of drawing gas that unit is reduced in the case where heating load is constant, or the pattern using low vacuum (or saying high back pressure) heating
To reduce the hot quality discrepancy in this part.Because hot water in heating network and the outside temperature difference are larger, although having standard in industry to pipe
Net surface heat loss limit value has regulation, but the heat loss of extensive heating network is still very big, and actual test result shows, part city
The actual heat loss of heating network in city even can be close to 50%.
Utility model content
In view of the deficienciess of the prior art, the utility model aims to provide the confession of a kind of heat pump and power plant cycle water coincidence
Heating system, to reduce the energy consumption during resident's heating.
The technical solution adopted in the utility model principle be the recirculated water by the use of plant condenser outlet as low-temperature heat source,
Hot water is produced using large-scale compression formula heat pump to heat for resident.
Specifically, the heating system of heat pump and power plant cycle water coincidence, including condenser, cooling tower, heating pump, pipe
Net, compression heat pump, water circulating pump etc., condenser outlet are connected with heating pump intake, heating pump discharge and heating network phase
Connection, the cold water intake-outlet of compression heat pump are connected with pipe network, and heating network return pipe is connected with cold water tower bottom.It is cool
Water tower is connected by water circulating pump with condenser.
Tthe utility model system is simple in construction, heating process heat loss very little, by increasing capacitance it is possible to increase the delivery of power plant, improves electricity
The peak modulation capacity of factory, the generation of electricity by new energy amount such as wind-force, solar energy can also be effectively dissolved during large-scale application.
Brief description of the drawings
Accompanying drawing is system diagram of the present utility model, does not wherein connect residual heat from boiler fume in the embodiment shown in accompanying drawing 1

In embodiment as shown in Figure 1, the coolant outlet of condenser 3 of steam turbine 1 is connected with the entrance of heating pump 4,
It is connected simultaneously with cooling tower 7.The outlet of heating pump 4 is connected with the entrance of heating network 5, and the cold water of compression heat pump 6 enters
Outlet is connected with heating network 5 for return pipe respectively.The return pipe of heating network 5 is connected with cooling tower 7, cooling tower 7
It is connected simultaneously by water circulating pump 9 with the cooling water inlet of condenser 3.
At work, the cooling water flowed out by condenser 3 is divided into two parts to the system, is partly into heating pump 4 and enters
Mouthful, it is sent into by heating pump 4 in heating network 5；Another part, which then enters in cooling tower 7, to be cooled down.Used in the heat such as residential block, commercial building
Large-scale compression formula heat pump 6 is nearby built at family, and the low-temperature heat source of compression heat pump 6 is provided by the recirculated water in heating network 5, compression
Hot water caused by formula heat pump 6 is the heating of the heat users such as residential building, commercial building.The heating network 5 after the cooling of compression heat pump 6
Interior backwater is flowed into cooling tower 7, and the recirculated water of the bottom of cooling tower 7 is sent into condenser 3 by water circulating pump 8, for cooling down vapour
The steam discharge of turbine 1.
In embodiment as shown in Figure 2, the outlet of heating pump 4 is connected with the entrance of smoke waste heat exchanger of boiler 10, boiler
The outlet of smoke gas afterheat heat exchanger 10 is connected with the water inlet of heating network 5, exports in heating pump 4, smoke waste heat exchanger of boiler
10 inlet and outlet are mounted on valve 11.
The system at work, the recirculated water exported by heating pump 4 enter smoke waste heat exchanger of boiler 10 in continue by
Heat improves temperature, while carries out fume afterheat utilization to boiler, and the recirculated water after heating enters back into heating network 5, is compression
Heat pump 6 provides low-temperature heat quantity.
The utility model is not limited to above-mentioned embodiment, and anyone can draw other under enlightenment of the present utility model
Various forms of products.However, make any change in its shape or structure, it is every same or like seemingly with the utility model
Technical scheme, within its protection domain.
