The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
It is shown in Figure 1, a kind of geothermal heating operating system of accumulation of heat and multistage terminal user's combined heat, comprising:
Two heat exchangers 4 in parallel and two concatenated heat pump units 7, the GEOTHERMAL WATER inlet port of two heat exchangers in parallel
43 are set the GEOTHERMAL WATER piping connection of desander 2 to geothermal well 12, and accumulation of heat water is equipped between the desander and heat exchanger
Pond 3, the thermal storage tank are connected in parallel with desander；The heating hot water feed water inlet 42 of two heat exchangers in parallel is connected to level-one
The tail water mouth 41 of the water segregator 5 of heating plant, two heat exchangers in parallel is connected to inverted well 13；Second level heating plant catchments
The hot water backwater outlet of device 6 is connect with hot water backwater's entrance of two concatenated heat pump units, the heat-exchanging water of the heat pump unit
Outlet is connect with the heat exchange water inlet 44 of two heat exchangers in parallel.
Wherein, there is water pump 8 in the thermal storage tank 3, hot water is pumped into two heat exchangers in parallel.Thermal storage tank
3 connect the water outlet of desander 2 by a water inlet pipe, are entered by the GEOTHERMAL WATER of another pipe connection in parallel and heat exchanger
The underground heat water lines that mouth 43 is connected
Wherein, there is water-circulating pump 1 in the geothermal well.
Wherein, the tail water mouth of two heat exchangers 4 in parallel, which is connected on the water return pipeline of inverted well 13, tail water recirculation water
Pump 11.
Wherein, the hot water backwater of the hot water backwater outlet and two concatenated heat pump units of the water collector of second level heating plant
There is the water-circulating pump 9 of mutual backup on the pipeline of entrance connection.
The utility model supplying hot water is the GEOTHERMAL WATER heating unit and connection heat pump unit by connection geothermal well pump house
Heat supply water unit composition.
Wherein, in GEOTHERMAL WATER side, GEOTHERMAL WATER is after desander, into thermal storage tank or heat exchanger, extracts heat through heat exchanger
After amount, geothermal tail water recharge to inverted well.
In supplying hot water side, multi-stage user supplying hot water passes through floor panel heating after flowing through radiator user (primary user)
User's (secondary user's note) enters heat exchanger subsequently into heat pump unit after heat release, supply after promoting temperature for radiator user
