Abstract
The utility model discloses an automatic control combined heat transfer well, which relates to an improvement of the structure of an underground heat transfer well, in particular to an improvement of the structure of a single cycle pumping well and overcomes the disadvantage of large recirculation amount existing in the current single cycle pumping well and improves collecting ability. The structure of the automatic control combined heat transfer well is that: the single cycle pumping well is provided with an immersible pump, a temperature detecting head and a lacquer disk sealing device for well; the immersible pump is connected with a heat exchanger through pipes, a return pipe is provided with a tee coupling and electrical valves are arranged on the return pipes which are between the tee coupling and the single pumping well, a recharge well. The inner upper part of the recharge well is provided with a float valve and the electrical valves, the float valve and the temperature detecting head are connected with an automatic control box. The utility model has the advantages that the water temperature in the automatic control maintains comparatively high, thereby improving the collecting ability.
Description
Technical field:
The invention is to be used for the underground heat exchange well, is to utilizing underground heat (energy) to carry out the improvement of the heat exchange well structure of heat (cold) exchange, especially individual well being circulated and take out the improvement of irritating well construction.
Background technology:
Utilize underground heat (energy) to carry out the heat exchange well of heat (cold) exchange.Existing dual mode, the one, the filling mode is taken out in the individual well circulation, and two is that a well is taken out many wells recycling mode.Though the individual well circulation is taken out the filling mode and has been overcome problems such as recharging difficulty, has reduced acquisition capacity.Though and many wells recycling mode acquisition capacity is stronger, but exist problems such as inverted well silts up.These two kinds of technology all in various degree constraint the development and use of this technology.
Summary of the invention:
The purpose of the invention provides a kind of automatic control combined type heat exchange well that filling well acquisition capacity is taken out in the individual well circulation that improves; The purpose of the invention is to realize by following technical scheme: control the combined type heat exchange well automatically, comprise the singlewell pumping well, immersible pump, the temperature detecting head, well lacquer disk(-sc) sealing device, heat exchanger, automatic control box, immersible pump, the temperature detecting head, well is installed in respectively in the singlewell pumping well with the lacquer disk(-sc) sealing device, heat exchanger links to each other with immersible pump by the road, water return pipeline is installed in the singlewell pumping well, automatic control box is connected with the temperature detecting head, it is characterized in that three-way connection being installed at the return pipe of drawing from heat exchanger, at three-way connection and go on the pipeline between the singlewell pumping well electrically-controlled valve is installed, at the surplus termination water return pipeline of three-way connection in inverted well, on its water return pipeline, electrically-controlled valve is installed, electrically-controlled valve is connected with automatic control box, ball-cock assembly is installed in the inverted well, and links to each other with automatic control box.
Automatically control combined type heat exchange well working procedure: take out and irritate when starting, the electrically-controlled valve of guiding on the water return pipeline of inverted well is closed under automatic control box control, the electrically-controlled valve of recharging on the water return pipeline of singlewell pumping well is opened under the control of automatic control box, backwater through heat exchanger recharges in the singlewell pumping well, big when recharging the water yield, the ground water temperature of collection is reduced, can not satisfy the requirement of collecting temperature, the signal of temperature detecting head induction this moment, pass to automatic control box, automatic control box is closed the former electrically-controlled valve of opening, and former electrically-controlled valve of closing is opened, backwater after the heat exchanger heat exchange, recharge in the inverted well through the electrically-controlled valve of opening, the singlewell pumping well is not subjected to the influence of backwater, and water temperature rises gradually, satisfy the collecting temperature requirement, when the ball-cock assembly in the inverted well was worked, the full signal of water passed to automatic control box, under the effect of automatic control box, with former electrically-controlled valve of closing, promptly the electrically-controlled valve on the singlewell pumping well water return pipeline is opened; The former electrically-controlled valve of opening is closed, the electrically-controlled valve that is about in the pipeline on the inverted well is closed, backwater directly recharges in the singlewell pumping well, when the backwater amount big, again coolant-temperature gage is reduced, in the time of can not satisfying the collecting temperature requirement, the temperature detecting head passes to automatic control box with water temperature signal again, enters the next action that comes and goes.
The advantage of the invention: irritate aboveground inverted well and two electrically-controlled valve of having increased by taking out in the individual well circulation, under the control of automatic control box, electrically-controlled valve can realize closing automatically, opening according to water temperature, makes the coolant-temperature gage of collection remain at higher level, has improved acquisition capacity.
Description of drawings:
Fig. 1 is a structural representation of controlling the combined type heat exchange well automatically.
The specific embodiment:
Automatically control the combined type heat exchange well: constitute with lacquer disk(-sc) sealing device 9, heat exchanger 10, automatic control box 5, ball-cock assembly 4, inverted well 3, electrically-controlled valve 6,7 by singlewell pumping well 1, immersible pump 8, temperature detecting head 2, well; Immersible pump is installed in singlewell pumping well inner bottom part, link to each other with heat exchanger by the road, the temperature detecting head is installed in singlewell pumping well inner bottom part, link to each other with automatic control box through lead, with well being installed in the singlewell pumping well with the layering according to actual needs of lacquer disk(-sc) sealing device, water return pipeline after the heat exchanger heat exchange is installed in the singlewell pumping well, a three-way connection is installed on water return pipeline, electrically-controlled valve 7 is installed on the water return pipeline between three-way connection and the singlewell pumping well, at the remaining termination water return pipeline of three-way connection in inverted well, electrically-controlled valve 6 is installed on its water return pipeline, ball-cock assembly is installed in the top of inverted well, electrically-controlled valve 6,7, ball-cock assembly links to each other with automatic control box.
