Description of drawings
Fig. 1 is the structural representation of single well type collecting apparatus of the present invention.
The specific embodiment
As shown in Figure 1, wherein described a kind of single well type collecting apparatus, it comprises the lifter 50 that heat-collection well 10 is connected with heat-collection well 10.Lifter 50 comprises by what evaporimeter 51, compressor 52, condenser 53 and expansion valve 54 were formed and heats the loop.The outlet side of lifter 50 links to each other with user load, wherein 81 expression circulating pumps, 82 expression wind dish groups.Described first balanced reservoir 71 and second balanced reservoir 72 form integrated water tank 70.By dividing plate 75 integrated water tank 70 is divided into first balanced reservoir 71 and second balanced reservoir 72.
The outlet pipe 61 of heat-collection well 10 is communicated with first interface tube 65 of first balanced reservoir 71 and lifter 50 respectively.The return pipe 62 of heat-collection well 10 is communicated with second interface tube 67 of second balanced reservoir 72 and lifter 50 respectively.One end of first tube connector 73 is communicated with the pipe joint 63 of outlet pipe 61 of the other end connected set hot well 10 of first balanced reservoir, 71, the first tube connectors 73.One end of second tube connector 74 is communicated with the pipe joint 76 of return pipe 62 of the other end connected set hot well 10 of second balanced reservoir, 72, the second tube connectors 74.
Described heat-collection well 10 comprises vertical shaft 1, is provided with water sucting cavity 2, accumulator 13, pump chamber 21 in described vertical shaft 1 from bottom to top successively.Described accumulator 13 the below that the position is positioned at level of ground water is set.Interval between the borehole wall of accumulator 13 and vertical shaft 1 is to guarantee that backwater is all extruded vertical shaft 1 is advisable, with the rate of heat exchange between reinforcement and the stratum.Too little at interval meeting increases resistance to water-flow.One end of suction hose 6 connects immersible pump 22.The other end of suction hose 6 passes accumulator 13 and is positioned at water sucting cavity 2, and the outlet pipe 61 of the delivery port connected set hot well 10 of immersible pump 22, an end of the drainpipe 11 of heat-collection well 10 pass accumulator 13 and be positioned at water sucting cavity 2.The other end of the drainpipe 11 of described heat-collection well 10 connects an end of control valve 30, the return pipe 62 of the other end connected set hot well 10 of control valve 30.
Between the borehole wall 15 of the sidewall of accumulator 13 and vertical shaft 1, has space 3.Accumulator 13 has the passage for the underground water turnover.Be provided with check valve 8 between described accumulator 13 and the water sucting cavity 2, make underground water can only unidirectionally enter accumulator 13.In the outlet pipe 61 of heat-collection well 10, between the delivery port of immersible pump 22 and pipe joint 63, be provided with non-return valve 28.In accumulator 13, be provided with the vent valve 26 that is communicated with ambient atmosphere, between accumulator 13 and pump chamber 21, be provided with sealing device 24.
In order to prolong the service life of heat-collection well 10, the enough sand setting collecting chamber (not shown)s of capacity can be left in the bottom of the water sucting cavity 2 in vertical shaft 1.
Contrast accompanying drawing 1 is described the running of single well type heat collector provided by the invention below.
As shown in Figure 1, in single well type heat collector provided by the invention, immersible pump 22 and control valve 30 interlocks are provided with, and when immersible pump 22 was opened, control valve 30 was closed.Otherwise when immersible pump 22 cut out, control valve 30 was opened.
Underground water enters water sucting cavity 2 by the annular space 3 between the accumulator 13 and the borehole wall 15.
Immersible pump 22 will be pumped into first balanced reservoir 71 and lifter 50 by outlet pipe 61 by the underground water that suction hose 6 sucks.Because the present invention does not relate to the improvement of riser configuration, in order to simplify description, does not describe the structure and the running of lifter in this article in detail.Name that can the REFERENCE TO RELATED people about the structure of lifter and running is called " geothermal energy-storage air conditioner system that hot water can be provided ", and the patent No. is 02205880.X or referring to the patent document of being mentioned in the background technology.
The underground water that enters lifter 50 in lifter 50 by release heat or absorb heat, heat or the power conversion of freezing after low temperature or high-temperature water enter second balanced reservoir 72.Because first and second balanced reservoirs 71 and 72 all are closed tanks, along with the water yield that enters in first balanced reservoir 71 and second balanced reservoir 72 increases, the water level in balanced reservoir increases gradually, and the pressure in balanced reservoir increases gradually thereupon.The water yield in entering first balanced reservoir 71 and second balanced reservoir 72 increases gradually, and the pressure in first balanced reservoir 71 reaches predetermined value, for example 4Kg/cm
2The time, no longer enter first balanced reservoir 71 from the underground water of immersible pump 22, and only supply subsurface water to lifter 50.When second balanced reservoir, 72 internal water pressures are increased to predetermined value, 4Kg/cm for example
2The time, immersible pump 22 cuts out, and simultaneously, control valve 30 is opened.At this moment, water in first balanced reservoir 71 enters lifter 50 and carries out heat exchange under the effect of water tank internal pressure, the water that from lifter 50, returns with from the water of second balanced reservoir 72, under the effect of second balanced reservoir, 72 internal pressures, enter in the water sucting cavity 2 by drainpipe 11.Under pressure, the water of discharging from drainpipe 11 is pressed into the annular space 3 between water sucting cavity 2, accumulator 13 and the borehole wall 15, and the stratum around the vertical shaft 1, carries out heat exchange with the underground water that is present in this.Water in first balanced reservoir 71 and second balanced reservoir 72 flows out gradually, and pressure drops to predetermined value, for example 1.5Kg/cm gradually
2The time, immersible pump 22 starts, and control valve 30 is closed, and supplies subsurface water to first balanced reservoir 71, lifter 50 and second balanced reservoir 72 once more, begins next working cycles.
Above content only is the preferred embodiments of the present invention.What should emphasize is that under the prerequisite that does not break away from inventive concept, those of ordinary skills all should be included within protection scope of the present invention various modification or the improvement that the present invention makes.
