The longhole heat exchanger is characterized in that a water circulation heat exchanging pipe is arranged in a metal outer well pipe; sieve-shaped perforations are formed in the pipe wall of the metal outer well pipe at intervals; a PE spiral pipe is arranged in the water circulation heat exchanging pipe; an upper blocking plug and a lower blocking plug are separately and fixedly arranged on the upper end part and the lower end part of the PE spiral pipe; a pump chamber shell is hermetically and fixedly arranged on the upper end part of the water circulation heat exchanging pipe; the pump chamber shell communicates with the water outlet end of the PE spiral pipe through the upper blocking plug; a deep well submersible pump is arranged in the pump chamber shell; a water inlet through hole is formed in the side wall of the bottom part of the water circulation heat exchanging pipe and communicates with the water inlet end of the PE spiral pipe through the lower blocking plug; and geothermal deep well thermal energy is converted into hot water thermal energy by the longhole heat exchanger, and the longhole heat exchanger has the characteristics of being novel, reasonable and simple in structure, reliable for use and good in energy-saving effect.
Description
Technical field
The invention belongs to geothermal energy resources development technique, relates generally to a kind of geothermal energy heat exchanger。
Background technology
Geothermal Well Prospecting at northern China extremely frigid zones becomes in well construction, frequent spot hot well Cheng Jinghou temperature is significantly high, but the technical problem that the water yield is little, its main cause is that underground only has enough temperature without enough groundwater run offs so that the underground heat well water of extremely frigid zones develops and is affected。
Summary of the invention
The purpose of the invention is aiming at above-mentioned prior art Problems existing, and design provides the geothermal well deep hole heat exchanger of a kind of new construction, reaches to increase groundwater run off, makes shaft bottom geothermal energy be converted to heat energy in water, meets the purpose of user's requirement。
The Basic Design of the invention is: geothermal well deep hole heat exchanger includes deep well submerged pump, the equipped water circulation heat exchange pipe of spacing is left in metal outer well tube, on described metal outer well tube tube wall, interval arranges sieve-like perforation successively from top to bottom, PE serpentine pipe is arranged in inside water circulation heat exchange pipe, in described water circulation heat exchange pipe, it is positioned on the upper and lower end of PE serpentine pipe and is fixedly mounted with closure plug and lower closure plug respectively, on described water circulation heat exchange pipe upper end, it is positioned at closure plug upper seal and is fixedly mounted with pump chamber housing, described pump chamber housing is connected with PE serpentine pipe water side by upper closure plug, described deep well submerged pump is arranged in pump chamber housing, on described water circulation heat exchange pipe bottom side wall, it is positioned at position, lower closure plug downside and inlet through hole is set, described inlet through hole is connected with PE serpentine pipe water inlet end by lower closure plug。
The invention achieves geothermal deep well heat energy and is converted to hot water heat energy, is effectively utilized deep-well geothermal energy, to reach and to meet user's requirement。This device novel structure, rationally, simple, use reliable, good energy-conserving effect, develop for the underground heat well water of the vast cold area in north of China and provide technical support。
