Description

Geothermal heat exchanger convenient to install

Technical Field

The utility model belongs to the technical field of geothermal heat exchanger, specifically indicate a geothermal heat exchanger convenient to installation.

Background

Geothermal energy is natural heat extracted from the earth's crust, from lava rock inside the earth, in the form of heat, which is extracted directly from the heat sources in the simplest and most cost-effective way. The average ground temperature gradient of China is about 3 ℃/100 meters. I.e. the ground temperature increases about 3 ℃ for every 100 meters downwards increase under the constant temperature layer. 1000-4000 meters underground, and the ground temperature is about 50-135 ℃. The temperature of the intermediate-deep geothermal resources is not enough to be developed and used for generating electricity, but can be a stable heat source for supplying heat to buildings. At present, the geothermal heat exchanger can obtain heat energy under the condition of not pumping underground water, but the construction cost of the geothermal heat exchanger is higher, and the geothermal heat exchanger is positioned in an underground deep layer, so that the installation and the maintenance are inconvenient, the operation cost is increased, and the popularization and the use of the technology are restricted.

The utility model adopts the following technical scheme: the utility model discloses geothermal heat exchanger convenient to installation, including outer tube, interior sleeve pipe and lifting unit, the outer tube includes diapire, diapire and lateral wall down, it makes outer tube formation sealed cavity tubulose setting to go up diapire, diapire and lateral wall down, be equipped with on the upper wall and collect mouth and filling opening, interior sleeve pipe is both ends open-ended cavity tubulose setting, interior sleeve pipe one end is located and is collected the mouth on the other end locate in the outer tube, it is equipped with two lift passageways to run through the diapire in the outer tube and go to the bottom the wall, lifting unit includes two lifting screw, elevator motor and connecting band, all locate the screw thread on the lifting screw and in the lift passageway, the rotatable lifting screw of locating in the lift passageway, the connecting band is connected it in two lifting screw one end, elevator motor locates on the lifting screw.

Furthermore, the inner sleeve is provided with a heat insulation layer, so that loss in the heat collection process is prevented.

Furthermore, a circulating medium is injected into the outer sleeve, and the circulating medium is water.

Preferably, the outer sleeve is made of J55 or N80 or P110 oil steel pipe.

Preferably, the length of the outer sleeve is 1.2 to 1.5 times of the length of the inner sleeve.

Adopt above-mentioned structure the utility model discloses the beneficial effect who gains as follows: the utility model discloses geothermal heat exchanger easy operation convenient to installation combines together heat exchanger and elevating gear, changes traditional length great, the installation degree of difficulty is higher, the higher heat exchanger of construction cost of maintenance into simple installation, reduces the maintenance change expense to reduce the manufacturing cost of heat exchanger, under the condition that does not change the geothermal effect of gathering greatly reduced the cost of making, maintaining, ann tearing open, increased geothermal exploitation's whole operation income, had extensive popularization and application meaning.
