The geothermal pipe 500 may include a heat insulating portion for reducing the heat exchange efficiency between the inside and the outside of the geothermal pipe 500.

The heat insulating part may be formed with at least one heat insulating material along the surface of the geotechnical pipe 500 and may be provided in the space between the outer and inner pipes of the dual pipe type geothermal pipe 500 including the outer and inner pipes Can be advantageous.

In this configuration, the heating medium injected into the geothermal column 400 and the heat medium heated by the geothermal heat exchange heat with each other through the geothermal connection pipe 500 during the circulation of the heating medium inside the geothermal column 400 And it may be advantageous to improve the efficiency of the geothermal heat recovery.

The structure of the cover 300 described above is provided at the upper part of the structure of the tile passive 400 and the tile pass pipe 500 to seal the upper surface of the tile pass 400 and to seal the inner space of the tile pass 400 It can be formed as a closed channel.

That is, the inlet of the geothermal heat pipe 400 may be formed so as to be closed so that the remaining portions except for the portion connected to the geothermal heat recovery passage 100 and the heat medium supply passage 200 are not communicated with the ground.

At this time, the sealing portion 330 of the cover 300 comes into contact with the upper end of the paper dust trapping pipe 500 to isolate the inside and the outside of the paper dust trapping pipe 500, It is possible to prevent the tablets from communicating with each other.

In order to prevent the inflow of air through the ground in the inner space of the geothermal column 400, the upper and lower portions of the geothermal and / It may be advantageous that the structure of the wafer W is further included.

Such a configuration can obtain the effect that the geothermal heat recovery system according to the present invention forms a more closed flow path.

The main pump 600 is connected to the geothermal heat recovery passage 100 connected to the inner side of the geothermal return pipe 500 to recover the heat medium inside the geothermal power system 400. It may be a configuration corresponding to the first pump in the geothermal recovery circulation apparatus.

In this embodiment, the main pump 600 is connected to the geothermal heat recovery channel 100 to provide power for recovering the heated heating medium from the production chamber inside the geothermal pipe 500 to the ground.

The auxiliary pump 700 is connected to the heating medium supply passage 200 connected to the outer side of the geotechnical pipe 500 and supplies the heating medium to the inside of the geotechnical station 400. In the present invention, And the second pump in the geothermal recovery circulating apparatus according to the present invention.

In this embodiment, the auxiliary pump 700 is connected to the heating medium supply passage 200 to provide power for injecting the heating medium into the injection hole, which is the outer side of the geotechnical pipe 500.

That is, the main pump 600 and the auxiliary pump 700 may be provided on the outside of the DPF 400, that is, on the ground.

The use of the geothermal recovery system according to the present invention including such a construction will be described in more detail as follows.

3 and 4, in the course of lifting the heated heat medium inside the production chamber of the geothermal column 400 to the ground, the main pump 600 for recovering the production definition heat medium is disposed in the geothermal return channel 100 The height at which the main pump 600 is installed may be the same as the height H1 at which the geothermal heat recovery flow path 100 protrudes upward.

In this case, it is possible to apply a variety of pumps, which are generally inexpensive and relatively inexpensive to the main pump 600, without using an underwater pump, thereby achieving cost reduction effects.

In addition, since the main pump 600 is provided on the ground to improve the accessibility, maintenance such as maintenance of the pump and replacement of the pump can be facilitated.

However, since the main pump 600 is higher than the ground surface H1 in the present embodiment, the load applied to the main pump 600 may be relatively higher than that of the pump provided inside the geothermal control unit 400. [

In this case, the geothermal heat recovery system according to the present invention may include the auxiliary pump 700 because the main pump 600 needs to be provided with a higher output pump or a failure due to a high load may occur .

The auxiliary pump 700 can intentionally apply pressure to supply the heating medium to the heating medium 400 when the heating medium is supplied thereto so that the heating medium is not supplied using only gravity.

When the pressure of the heating medium supplied to the injection chute is increased, the total internal pressure of the geothermal control system 400 is increased, and the heating medium recovered from the production well is also recovered to a relatively high pressure. Effect can be obtained.

That is, the auxiliary pump 700 may be configured to compensate for a load that rises as the arrangement of the main pump 600 increases.

At this time, it is advantageous that the main pump 600 and the auxiliary pump 700 are provided at the same height.

In this case, it is possible to obtain an effect of reducing the load due to the height difference of the height of the main pump 600 and the auxiliary pump 700.

In addition, it may be advantageous that the main pump 600 is provided to have a relatively large output as compared with the auxiliary pump 700.

Basically, the power required for the heat medium flow in the geothermal heat recovery system according to the present invention is provided by the main pump 600, and the auxiliary pump 700 is provided for canceling the load of the elevated height so that the main pump 600 is installed on the ground It is possible to provide only the power for.

Therefore, a plurality of pumps having the same output need not be provided, so that the auxiliary pump 700 can use a relatively low-output pump with a low output.

Such a configuration can reduce the cost of manufacturing and managing the geothermal heat recovery system according to the present invention.

Meanwhile, air may be introduced into the inside of the geothermal heat system 400 of the geothermal heat recovery system according to the present invention for some reason.

In this case, since the internal heat medium is received by the main pump 600 to be discharged to the outside, an air layer may be formed on the upper portion of the injection well as shown in FIG.

In this case, the height H1 at which the position of the main pump 600 is higher than the water surface of the heating medium becomes the height H3 at which the height is increased, and the load applied to the main pump 600 can be larger.

Accordingly, the air layer formed inside the trough 400 is discharged to the outside through the valve unit 320 to raise the level of the heating medium, thereby preventing an increase in the load applied to the main pump 600 .

At this time, it is possible to check the water level of the heating medium inside the geothermal control unit 400 through the above-described sensor unit 310 and to immediately cope with the lowered water level.

In addition, it is also possible to prevent air from being generated inside the geothermal control unit 400 by applying the configuration of the partition wall W described above.

It is possible to provide a pump of the geothermal pump system for recovering the geothermal heat from the geothermal heat through the geothermal heat recovery system and the geothermal heat recovery system according to the present invention, .

In addition, it is possible to utilize relatively inexpensive and various pumps, thereby reducing the construction and management cost of the geothermal heat recovery system.

In addition, a relatively low-output pump can be applied and the load on the pump can be reduced.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is self-evident to those of ordinary skill in the art. Accordingly, it should be understood that such modifications or alterations should not be understood individually from the technical spirit and viewpoint of the present invention, and that modified embodiments fall within the scope of the claims of the present invention.
