The utility model and existing geothermal utilization method something in common are that the deep-well of beating is all arranged, and all are to gather heat energy from underground water; Difference is that existing geothermal utilization method will be extracted into ground with underground water, and the utility model need not be extracted into the underground water in the well on the ground, can directly gather heat energy the underground water in well, then the underground heat of being gathered be delivered to ground, used for heating.With reference to Fig. 1, evaporimeter (1) is placed on water (7) lining of well (11), and working media (12) is housed in it.We know that the boiling point of general liquid substance is relevant with its residing environmental pressure, and environmental pressure is low more, and boiling point is also just low more.According to this principle, before device is used, we are that evaporimeter (1) vacuumizes with vavuum pump at first, reduce the pressure in the evaporimeter (1), also reduced the boiling point of the interior working media of evaporimeter (1) (12) thereupon, when the boiling point of working media (12) is lower than the water temperature of water (7) of well (11) widely till.Like this, the working media (12) in the evaporimeter (1) will undergo phase transition, and is evaporated to gas by liquid, absorbs a large amount of heats simultaneously.Because evaporimeter (1) is placed on water (7) lining of well (11), so the heat that it absorbs all is water (7) lining; We can say that also evaporimeter (1) has been gathered a large amount of heat in water (7) lining.Therefore say that evaporimeter (1) is a heat energy collecting device of the present utility model.
With reference to Fig. 1, evaporimeter (1) top communicates with an end of heat supply pipeline (2), and the other end of this pipeline communicates with the import of thermal energy converter (3) lining coiled pipe (4).So, the gas that produced of the evaporation of the working media (12) in the evaporimeter (1) will enter coiled pipe (4) lining along heat supply pipeline (2).Working media (13) is equipped with in described thermal energy converter (3) lining.The propagation law of heat energy is to be flowed to lowly by height, that is to say, and be that the high material of temperature is passed to the low material of temperature with heat energy.Because working media (13) is lower than the temperature of working media (12), therefore, the outer working media (13) of the working media (12) of coiled pipe (4) lining and coiled pipe (4) carries out thermal energy exchange, and partial heat energy has been passed to working media (13).Working media (13) has absorbed a large amount of heat energy, and temperature raises.Working media (13) after temperature raises is sent to the end with heat after being sent heat pump (8) pressurization, and working media (12) is because of losing heat energy, and temperature decline causes undergoing phase transition once more, becomes liquid by gas.With reference to Fig. 1, the outlet of coiled pipe (4) communicates with the import of gas-liquid separation valve (5), and the outlet of gas-liquid separation valve (5) communicates with an end of back liquid pipeline (6), and the other end of this pipeline inserts in the evaporimeter (1).So, the working media (12) that coiled pipe (4) lining becomes liquid will turn back to evaporimeter (1) lining by gas-liquid separation valve (5) and back liquid pipeline (6), has finished once circulation.
Should be evaporimeter (1) inside and coiled pipe (4) inside before device of the present utility model uses and vacuumize, can use after vacuum inner when evaporimeter (1) and that coiled pipe (4) is inner is qualified.How to vacuumize? with reference to Fig. 1, valve (f1) and vavuum pump (9) are housed also on the described heat supply pipeline (2); Valve (f1) and vavuum pump (9) are in parallel, and a valve (f3) is equipped with in the import of vavuum pump (9), and three-way pipe is equipped with in outlet, and a valve (f2), (f4) are respectively adorned in the two ends in addition of three-way pipe; The other end of valve (f2) communicates with coiled pipe (4) import, and the other end emptying of valve (f4) communicates with atmosphere.When vacuumizing, should first valve-off (f1), (f2) and (f5), open valve (f3), (f4), at this moment, evaporimeter (1) inside inner and coiled pipe (4) communicates with vavuum pump (9), vavuum pump (9) communicates with the device atmosphere outside again, and so, vavuum pump (9) just can vacuumize for its device.For device vacuumizes, pressure in the device can reduce, does what concrete device internal pressure drop to for qualified? this will be decided by the temperature of underground water (7) and used working media (12), and the pressure in its device will be lower than the saturation pressure of used working media (12) under the temperature of underground water (7).If with water as working media (12), the temperature of underground water (7) is 40 ℃, will what the pressure in its device be lower than for qualified? we know, in the time of 40 ℃, water saturation pressure is 7375pa, so to be lower than 7375pa just qualified for the pressure in the device.If with acetone as working media (12), the temperature of underground water (7) is 20 ℃, will what the pressure in its device be lower than for qualified? we know, in the time of 20 ℃, the saturation pressure of acetone is 27000pa, so to be lower than 27000pa just qualified for the pressure in the device.In the Beijing area, the ground water temperature of ground below hundred meters is about 10 ℃.Under this water temperature, the saturation pressure of acetone is 18500pa; The saturation pressure of ethanol is 3300pa; The saturation pressure of methyl alcohol is 25000pa.Hence one can see that under these conditions, so the pressure in the device should be lower than 18500pa, 3300pa and 25000pa respectively.Because of considering, along with the device running, the temperature of underground water (7) can descend, therefore suggestion, pressure in the device is lower by 20% than the saturation pressure of used working media (12) under the temperature of underground water (7), that is to say, when underground water temperature during 10 ℃ of left and right sides, as working media (12), the pressure in its device should be below 14800pa with acetone; As working media (12), the pressure in its device should be below 2640pa with ethanol; As working media (12), the pressure in its device should be below 20000pa with methyl alcohol.
Device of the present utility model also will pour into working media (12) toward evaporimeter (1) lining before using, how to pour into? with reference to Fig. 1, have a filling opening (10) on the described back liquid pipeline (6), valve (f5) is housed on the filling opening (10).When pouring into working media (12), cut off the power supply of vavuum pump (9), and valve-off (f3) and (f4), open valve (f5) simultaneously, working media (12) will be successfully in filling opening (10) inflow evaporator (1).The amount of pouring into of working media (12) generally accounts for the 40-60% of the inner total measurement (volume) of evaporimeter (1).Irritated work medium (12) valve-off (f5), and then opened valve (f3) and (f4) vacuumize for device.The inner qualified back of vacuum of device cuts off the power supply of vavuum pump (9), and valve-off (f3) and (f4), and this device just can use.
Device of the present utility model exhausts vacuum, has poured into work medium (12) and just can move, and the underground heat of being gathered can have been delivered to ground.Is the underground heat how device of the present utility model will deliver to ground again sent to hot end again? with reference to Fig. 1, heat transfer medium (13) is equipped with in described thermal energy converter (3) lining; Have import and export on the shell of thermal energy converter (3), be equipped with in this outlet and send heat pump (8); Send heat pump (8) and be communicated with, have pipeline to communicate with import on thermal energy converter (3) shell with hot end with the end of heat.So, as long as again for sending heat pump (8) to connect power supply, this pump will extract the heat transfer medium (13) after thermal energy converter (3) lining is heated, and it has been sent to hot end.
The utility model device also has a kind of operation method, when device of the present utility model is irritated the working media (12) that is over, also exhaust vacuum for device once more, after making the device internal pressure also qualified, do not cut off the power supply of vavuum pump (9), also valve-off (f3) not, valve-off (f4), and open valve (f2), and allow vavuum pump (9) work on, the working media (12) of the gaseous state that extracts is sent to coiled pipe (4) lining, allow coiled pipe (4) lining pressure raise, also impel simultaneously the boiling point and the saturation temperature of the gaseous working medium (12) that enters coiled pipe (4) lining to raise, thereby improved the adiabatic condensation temperature of working media (12), make it to satisfy with the terminal requirement of heat.
Described working media (12) can be a water, also can be low-boiling point materials such as acetone, ethanol, methyl alcohol.Which kind of specifically adopts, and it is fixed that this also will be come by the temperature of underground water (7).If the temperature of underground water (7) is higher than 40 ℃, working media (12) just can adopt water; If the temperature of underground water (7) is lower than 40 ℃, working media (12) preferably adopts low-boiling point materials such as acetone, ethanol, methyl alcohol.
Described heat transfer medium (13) can be a water, also can be other low-boiling point material, as long as the heat transfer efficiency height, flow resistance is little, and safety is just passable.
Provide two specific embodiments below, we are described further at this point:
The hot end of the usefulness of first example is for uncongealable chemical pipeline in winter, and it is 3 ℃ with the terminal temperature requirement of heat, and the temperature of the water (7) of well (11) lining is 10 ℃, and the temperature of atmosphere is 0 ℃ on the ground.Because the temperature of underground water (7) is lower than 40 ℃, so we adopt acetone to be used as working media (12), and inner and coiled pipe (4) pressure inside is reduced to below the 14800pa with evaporimeter (1) with vavuum pump.In the pressure environment of 10 ℃ and 14800pa, acetone will undergo phase transition, and is evaporated to gas by liquid, absorbs a large amount of heats of underground water (7) lining simultaneously.The acetone of per kilogram becomes gaseous state by liquid state will absorb about 558KJ heat.Absorb the acetone that heat becomes gaseous state and rise, enter in the heat supply pipeline (2), enter into coiled pipe (4) lining along heat supply pipeline (2) then from the top of evaporimeter (1).Because coiled pipe (4) is to be positioned at ground thermal energy converter (3), just equals BADIRE and risen on the ground so the acetone of gaseous state enters coiled pipe (4) lining.Heat transfer medium (13) is equipped with in thermal energy converter (3) lining, and coiled pipe (4) just is immersed in heat transfer medium (13) lining.Heat transfer medium (13) is subjected to the influence of atmosphere, and initial temperature is near 0 ℃.Because the gaseous state acetone temperature in the coiled pipe (4) is higher than the outer heat transfer medium (13) of coiled pipe (4), so heat transfer medium (13) radiating and cooling of gaseous state acetone outside coiled pipe (4) in the coiled pipe (4), when the temperature of gaseous state acetone drops to boiling point when following, gaseous state acetone begins to condense into liquid, and emits a large amount of heats.The acetone of per kilogram will be emitted about 558KJ heat by the gaseous state liquefy.Condense into liquid acetone and enter back liquid pipeline (6) lining by gas-liquid separation valve (5), suitable then back liquid pipeline (6) turns back to and is positioned at evaporimeter (1) lining, has finished once circulation.Acetone institute liberated heat in the coiled pipe (4) has all given coiled pipe (4) outer heat transfer medium (13), and the temperature of heat transfer medium this moment (13) will rise.Because the pressure of coiled pipe (4) is 14800pa, so the interior acetone of coiled pipe (4) boiling point at this moment should be 8 ℃.If the heat-transfer effect of thermal energy converter (3) is good, the temperature that can guarantee heat transfer medium (13) fully is more than 5 ℃.Because these 5 ℃ are higher than 3 ℃ that hot terminal temperature requires, therefore can connect power supply for sending heat pump (8), the heat transfer medium (13) after allowing this pump that thermal energy converter (3) lining is heated is sent to the end with heat, has used for it.
The hot end of the usefulness of second example is for warming, and it is 18 ℃ with the terminal temperature requirement of heat, and remaining is the same.Therefore we also adopt acetone to be used as working media (12), also with vavuum pump evaporimeter (1) inside and coiled pipe (4) pressure inside are reduced to below the 14800pa simultaneously.So, the acetone institute liberated heat in the coiled pipe (4) also can all award the outer heat transfer medium (13) of coiled pipe (4), and the temperature of heat transfer medium (13) also can rise simultaneously, but can not exceed 8 ℃.In the pressure environment of 14800pa, the boiling point of acetone is 8 ℃, exceeds 8 ℃ of boiling points that also just exceed acetone this moment.We know and exceed boiling point, condensing of acetone will stop, and also just no longer heat release that is to say simultaneously, and heat transfer medium (13) temperature can only be below 8 ℃.Because these 8 ℃ are lower than 18 ℃,, can not satisfy the terminal requirement of heat so temperature is too low.What if? this problem, we can solve with the pressure that increases coiled pipe (4) lining.Its way is, when device of the present utility model is irritated the working media (12) that is over, also exhaust vacuum for device once more, the device internal pressure make qualified after, do not cut off the power supply of vavuum pump (9), also valve-off (f3) not, valve-off (f4), and open valve (f2), allow vavuum pump (9) work on, the working media (12) of the gaseous state that extracts is sent to coiled pipe (4) lining, allow coiled pipe (4) lining pressure raise, and regulate the pressure of coiled pipe (4) lining with valve (f1), allow its absolute pressure maintain more than the 30000pa.In the pressure environment of 27000pa, the boiling point of acetone is 22 ℃.If the heat-transfer effect of thermal energy converter (3) is good, the temperature that can guarantee heat transfer medium (13) fully is more than 18 ℃, and therefore so, the problem that temperature is too low has also just solved.
