Abstract

PURPOSE:To enable to easily utilize geothermal energy, by a method wherein an inner pipe with a heat-insulated pipe wall is inserted into an outer wall with an end closed to consitute a double pipe, which is buried underground, cold water is fed from a part on the ground, heat is received underground, and a high temperature water is taken out. CONSTITUTION:The inner pipe 2 with the heat-insulated pipe wall is inserted into the outer pipe 1 with an end closed to constitute the doulbe pipe, which is buried underground. Cold water is fed in through a cold water inlet 3 to sequentially absorb geothermal energy at a deep underground part, hot water reaching the maximum temperature at the deepest part is moved upward through the inner pipe 2, and hot water is obtained through a hot water outlet 4. In this case, since the inner pipe 2 is heat-insulated, hot water moving upward can not loose heat to the side of cold water moving downward. In addition, since cold water has a high specific gravity and tends to move downward while hot water has a low specific gravity and tends to move upward, power cost required for circulating water for utilizing geothermal energy can be reduced as compared to that in a conventional case.

Description

【発明の詳細な説明】 この発明は、二重管を利用し、地中に入れることにより
従来誹り簡単な方法で地熱を利用する方法に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of utilizing geothermal heat using a double pipe and placing it underground, which is simpler than conventional methods.

従来は、１本の管な地中に挿入し、地下７１（を汲み上
げ、更に１本の貿を地中に挿入して使用済地下２１りを
地中に戻す方法が多く、汲上げ、坩中戻しの為の動力を
必要とした。Conventionally, there were many methods in which one pipe was inserted into the ground to pump up the underground 71, and another pipe was inserted into the ground to return the used underground 21 to the ground. Power was required for the return.

更に、汲上げた水の熱利用時に水中に慎まれる有害成分
及スケール除去に多くの対策を必要とした。Furthermore, many measures were required to remove harmful components and scale from the pumped water when it was used for heat.

本発明Ｃ：１前記の欠点を改良し１こ増熱利用方法に関

その有効なりノＬを失なう事がない。To explain this with a diagram, the inner tube 2 is inserted into the vertical tube 1 and buried underground. Cold water is sent through a cold water inlet 3 to sequentially collect geothermal heat deep underground, and hot water reaching a maximum of 2 grades in the deepest part is allowed to rise through an inner cylindrical pipe 2, and hot water is obtained from a hot water outlet 4. At this time, since the inner cylinder W 21 and the flange 1 are added, there is no loss of effectiveness on the cold water side when the temperature is rising (2) < 11 and falling.

It has characteristics. Note that the lid can be changed to any liquid, and the %IIjA* temperature can be arbitrarily selected depending on the lengths of the outer tube 1 and the inner tube 2.
