Arrow described in Fig. 2 is represented the phreatic flow direction.
Because when machining large-sized well casing, cost is higher, complex process.The present invention also can adopt two small size well casings, as second embodiment.
Fig. 3, the 4th, the cutaway view of horizontal gyrating type singlewell pumping heat-exchanger rig second embodiment of the present invention and the vertical view of down-hole part, as Fig. 3, shown in 4, I-steel 4 is set in well, well is divided into different chambeies, be respectively equipped with first well casing 3 ' and second well casing 3 that are processed with several through holes on the sidewall of equal diameters in two chambeies arranged side by side therein "; at first well casing 3 ' and second well casing 3 " in to be respectively equipped with first immersible pump 5 identical with first embodiment with second immersible pump 6 and other each several parts with second immersible pump, 6, the first immersible pumps 5.
In two embodiment of the present invention, be used to cut off the I-steel 4 of well or well casing, under the condition that some geologic structures allows, also can adopt dividing plate to replace I-steel, water turn round mobile route and can shorten in the stratum this moment.
With reference to Fig. 1 operation principle of the present invention and process be: I-steel is well 13 separated into two parts, a part is a high pressure chest, a part is a low-pressure cavity, when 5 work of first immersible pump are drawn water, corresponding second valve 2 is opened, the part at first immersible pump, 5 places will be low-pressure cavity this moment, the water of low-pressure cavity is transported in the heat exchanger 11 of well head by first immersible pump 5, carry out heat exchange with the medium in the heat exchanger 11, water after the heat exchange is by voltage-stablizer 12, second valve 2 enters second sleeve pipe 10 and delivers to high pressure chest, because the pressure differential of high pressure chest and low-pressure cavity, force the water of high pressure chest to return low-pressure cavity by the aperture stratum horizontal rotation on the tube wall, glide path as shown in Figure 2.Water returns in the process of low-pressure cavity with behind the soil heat exchange at high pressure chest and flows back into low-pressure cavity.The glide path of the width by regulating the I-steel central dividing plate or the pressure change water of voltage-stablizer 12 reaches the purpose of stabilizing low voltage cavity temperature.The width of central dividing plate is big more, and the route that water streams is long more, and the heat exchange between water and the soil is abundant more, otherwise the width of central dividing plate is more little, and the route that water streams can shorten, and the heat exchanging process between water and the soil shortens, and heat exchange is relatively poor; The pressure of voltage-stablizer is big more, and the flow velocity of water increases, and the flow path of water in soil becomes far away, and the heat exchange between water and the soil just fully.The present invention can only use an immersible pump 5 or 6 to carry out work, still, only uses a pump, when Groundwater Flow, drives the solid particle in the stratum inevitably, moves along water (flow) direction, and long-term use can cause the imbalance of stratigraphic structure.Therefore the present invention has designed two immersible pumps, and first immersible pump 5 and second immersible pump 6 are used alternatingly, and keeps the balance of stratigraphic structure, moves steadily in the long term to guarantee this device.
