Description
Technical field
The invention belongs to ground temperature energy development technique, relates generally to a kind of cold district ground temperature energy quarrying apparatus.
Background technology
During ground temperature in north cold area can develop, owing to winter temperature is low, the exploitation of ground temperature energy causes formation temperature near heat exchanging holes to reduce, forming Temperature Field cone of depression, if things go on like this, this heat exchanging holes can exploit, by not having ground temperature, the effect utilized, and existing ground temperature energy recovery method does not also have temperature raising, compensation device, making heat exchanging holes not continue for a long time, effectively carry out heat exchange, shorten the service life of heat exchanging holes, cold district ground temperature can develop and be affected.
Summary of the invention
The purpose of the invention is aiming at the problem that above-mentioned prior art exists, and designs the cold district ground temperature energy quarrying apparatus providing a kind of new construction, is designed by the structure carrying out temperature-compensating for heat exchanging holes, reaches to continue, effectively develop the purpose of ground temperature energy.
The Basic Design of the invention is: a kind of cold district ground temperature energy quarrying apparatus includes heat exchanging holes, source pump and circulating pump, core pipe is set in described heat exchanging holes, it is provided with spacing between described core tube wall face and heat exchanging holes internal face, constitute annular compartment, filter pipe is fitted on core pipe bottom, horizontal coiled pipe is laid on subsurface, at described heat exchanging holes outer periphery position, thermal compensation hole is set, annular compartment is connected by heat pump water inlet pipe with source pump, circulating pump is connected by circulating pump outlet pipe with core pipe, source pump is connected by heat pump outlet pipe with horizontal coiled pipe, thermal compensation hole is connected by circulating pump water inlet pipe with circulating pump, horizontal coiled pipe is connected by filling pipe with thermal compensation hole；Described thermal compensation hole is 1: n with the number ratio of heat exchanging holes.
The invention achieves exchanges the compensation of ground temperature at hot hole in cold district ground temperature energy development process, it is to avoid and eliminate the formation of Temperature Field cone of depression, and comprehensively utilizes the clean energy resourcies such as ground temperature energy, geothermal energy and solar energy, continue, effectively exploitation utilize ground temperature energy.This device is novel in design, rationally, simple in construction, use reliable, effects of energy saving and emission reduction is good, significantly extends heat exchanging holes service life, can continue for the ground temperature of the vast north cold area of China, Efficient Development utilization provides technical support.

Detailed description of the invention
Below in conjunction with the accompanying drawings the invention embodiment is described in detail.A kind of cold district ground temperature energy quarrying apparatus includes heat exchanging holes 3, source pump 5 and circulating pump 6, in described heat exchanging holes 3, core pipe 2 is set, it is provided with spacing between described core pipe 2 outside wall surface and heat exchanging holes 3 internal face, constitute annular compartment, filter pipe 1 is fitted on core pipe 2 bottom, horizontal coiled pipe 10 is laid on subsurface, at described heat exchanging holes 3 outer periphery position, thermal compensation hole 9 is set, annular compartment is connected by heat pump water inlet pipe 4 with source pump 5, circulating pump 6 is connected by circulating pump outlet pipe 12 with core pipe 2, source pump 5 is connected by heat pump outlet pipe 11 with horizontal coiled pipe 10, thermal compensation hole 9 is connected by circulating pump water inlet pipe 7 with circulating pump 6, horizontal coiled pipe 10 is connected by filling pipe 8 with thermal compensation hole 9；Described thermal compensation hole 9 is 1: n with the number ratio of heat exchanging holes 3.
During operation in summer, by circulating pump 6 from deep, thermal compensation hole 9 extraction hot water to core pipe 2, after hot water in core pipe 2 flow to the filter pipe 1 bottom it, enter in the annular compartment between heat exchanging holes 3 hole internal face and core pipe 3 outside wall surface, hot water is by heat exchanging holes 3 hole wall and surrounding formation generation heat transfer process, make formation temperature raise, reduce ground temperature in winter and can exploit the Temperature Field funnel caused；Meanwhile, the water extracted out from annular compartment is freezed by source pump 5, and when the water after refrigeration flows through underground horizontal coiled pipe 10, after solar radiation, water temperature raises；Again by the further temperature raising in filling pipe 8 is injected into thermal compensation hole 9 of the water after temperature raising.During winter job, being utilized as main with the exploitation of heat exchanging holes 3 ground temperature energy, meanwhile thermal compensation hole 9 also can directly be exploited as heat exchanging holes and be utilized ground temperature energy.
