Embodiment
With reference to accompanying drawing, the utility model is described in further details.
A kind of middle-shallow layer heat supply system sandy soil layer is incubated well, including feed pipe 5, feed pipe 5 and return pipe 6 bottom
Portion connects；The top insulation layer 2 of return pipe 6 surrounds, outside the heat-insulation layer 2 by the surround ring of soil layer 1 around；The return pipe
6 bottoms are surrounded by backfill material 4 and closed, and closing is surrounded by lithosphere 3 outside the backfill material 4；The top of feed pipe 5 and water inlet
Pipe 9 connects, and the water inlet pipe 9 is with water pump and is connected with the first heat pump main frame 7, the heat pump of the first heat pump main frame 7 and second
Main frame 8 is connected, and second heat pump main frame 8 is connected by outlet pipe 10 with the top of return pipe 6.The backfill material 4 is mixed
Solidifying soil, the heat-insulation layer 2 is foam cement or mineral wool.
As illustrated, the feed pipe 5 supplies water to whole system, the water of confession is the most hot water in geothermal well bosom, described
Hot water in feed pipe 5 enters the first heat pump master in the presence of the water pump of the water inlet pipe 9, by the feed pipe 5
Machine 7, after being extracted heat, temperature reduces, and into second heat pump main frame 8, after being extracted heat again, temperature is further
Reduce, entered by the outlet pipe 10 in the return pipe 6 and heated, wherein in the soil layer 1, because the soil layer
Water temperature is relatively low in 1, so need not exchange heat, if heat exchange may further reduce GEOTHERMAL WATER return water temperature, so by described
Heat-insulation layer 2 is incubated；Then heat supply backwater enters in the deeper lithosphere 3, and GEOTHERMAL WATER is higher by thermal conductivity factor
The backfill material 4 and the lithosphere 3 are fully exchanged heat, and according to geothermic gradient, underground heat backwater is more down warmmer, reaches bottom
Afterwards, underground heat return water temperature reaches highest, is then quickly drawn out and by described in the water inlet pipe 9 entrance by the feed pipe 5
First heat pump main frame 7 and second heat pump main frame 8 carry out heat supply, so circulation.
Above-mentioned embodiment is only intended to clearly illustrate the utility model example, and not to embodiment party
The restriction of formula.For those of ordinary skill in the field, other differences can also be made on the basis of the above description
The change or variation of form, there is no necessity and possibility to exhaust all the enbodiments, and thus amplify out aobvious and
The change or variation being clear to are still in the scope of protection of the utility model.
