Description
technical field:
The utility model relates to a kind of device eliminating underground Rock And Soil hot stack, belongs to earth source heat pump and develops corollary equipment technical field.
background technology:
Utilize underground ground temperature to stablize, not easily by the feature that temperature affects, by heat exchanger of air condition as underground, i.e. embedded underground vertical circulation water pipe (underground pipe), during cooling in summer, ground temperature may lower than temperature, and during heat supply in winter, ground temperature may higher than temperature.The amplitude utilizing heat pump to heat up or to lower the temperature is less, thus improves the efficiency of unit, has saved electric energy.Be suitable for utilizing soil Ground-Source Hot Pump air-conditioning system at middle and lower reach of Yangtze River hot-summer and cold-winter area.During summer air-conditioning, the heat energy of absorption is entered underground.During heat supply in winter, heat energy is drawn from underground.Ground temperature is the key of air conditioner heat exchange efficiency.Along with long-term using air-condition, the heat of the heat and sucking-off in winter that enter underground water annual summer repeatedly produces thermal unbalance, and make subsurface temperature raise continuously or reduce, be called " hot stack ", this can bring the reduction of heat pump operating efficiency and the change of geological environment, have impact on the exploitation of underground heat.
summary of the invention:
The purpose of this utility model provides a kind of device eliminating underground Rock And Soil hot stack for above-mentioned Problems existing, makes ground temperature remain on original ground temperature level, effectively solves the problem of hot stack, improve the efficiency of air-conditioning and saved energy consumption.
Above-mentioned object is realized by following technical scheme:
Eliminate the device of underground Rock And Soil hot stack, comprise the pumped well and inverted well that are separately positioned on both sides, underground pipe distributed area, described pumped well be arranged on described underground pipe distributed area downstream area and apart within described underground pipe 5 meters, described inverted well is arranged on the upstream region in described underground pipe distributed area apart from described underground pipe distributed area 50-60 rice, and the degree of depth of described inverted well and described pumped well is 80-120 rice.
The device of described elimination underground Rock And Soil hot stack, is provided with pumping conduit inside described pumped well, and described pumping conduit connects suction pump, and described suction pump connects to be arranged on by pipeline and recharges pipeline inside inverted well.
The device of described elimination underground Rock And Soil hot stack, the bottom of described inverted well is provided with sedimentation basin, blow-off line is provided with inside described sedimentation basin, described blow-off line connects slush pump, described mud delivery side of pump connects mud emission pipeline, and the outlet of described mud emission pipeline is arranged on the outside of described inverted well.
Beneficial effect:
1. the many experiments through inventor finds, when groundwater velocity is more than 10-6m/s, temperature with underground water diffusion obviously, when being greater than this groundwater velocity, effectively can eliminate the hot stack in soil, and its corresponding pump-out should be greater than 100m
3/ h.The utility model arranges pumped well and inverted well in both sides, underground pipe distributed area, and during cooling in summer, heat is entered underground by earth-source hot-pump system, and ground temperature is increased.Now, switch on the pump and draw water, make Groundwater Flow, flow velocity meets and exceeds 10-6m/s, and the ground temperature of rising can be taken away by underground water, is back to underground water upstream, fills into water-bearing layer, so circulate.Thus make ground temperature remain on original ground temperature level, effectively solve the problem of hot stack, improve the efficiency of air-conditioning and saved energy consumption.According to contrast, under the condition not having hot stack, the observable index conventional air-conditioning energy consumption of soil Ground-Source Hot Pump saves 20-30%.
2. be provided with sedimentation basin bottom inverted well of the present utility model, be convenient to timely blowdown, avoid sludge to manufacture into the not smooth situation of blocking of recharge well subsurface flow, reliability is higher.
accompanying drawing illustrates:
Fig. 1 is main TV structure schematic diagram of the present utility model.
In figure: 1, underground pipe, 2, pumped well, 3, inverted well, 4, pumping conduit; 5, suction pump; 6, pipeline is recharged; 7, sedimentation basin; 8, blow-off line; 9, slush pump; 10, mud emission pipeline.
detailed description of the invention:
As shown in Figure 1-2: the device of the elimination underground Rock And Soil hot stack of the present embodiment, comprise the pumped well 2 and inverted well 3 that are separately positioned on both sides, underground pipe 1 distributed area, described pumped well be arranged on described underground pipe distributed area downstream area and apart within described underground pipe 5 meters, described inverted well is arranged on the upstream region in described underground pipe distributed area apart from described underground pipe distributed area 50-60 rice, and the degree of depth of described inverted well and described pumped well is 80-120 rice.During cooling in summer, heat is entered underground by earth-source hot-pump system, and ground temperature is increased.Now, switch on the pump and draw water, make Groundwater Flow, flow velocity meets and exceeds 10-6m/s, and the ground temperature of rising can be taken away by underground water, is back to underground water upstream, fills into water-bearing layer, so circulate.Due to the distribution appearance of about 100 meters about underground greatly of underground water source, therefore pumped well of the present utility model and inverted well all will arrange the degree of depth that the degree of depth exceedes underground water source, object is to allow underground circulating water be taken away by unnecessary heat, be convenient to descend heat evenly, avoid the generation of hot stack, the well structure of pumped well of the present utility model and inverted well and construction technology should meet corresponding specification.
The device of described elimination underground Rock And Soil hot stack, is provided with pumping conduit 4 inside described pumped well, described pumping conduit connects suction pump 5, and described suction pump connects to be arranged on by pipeline and recharges pipeline 6 inside inverted well.Recharge from inverted well after water higher for heat being released from pumped well, the stable of geologic structure can be maintained, simultaneously because inverted well distance underground pipe distributed area is far away, unnecessary heat can fully be spread, do not produce hot stack, improve the heat exchange efficiency of air-conditioning, be beneficial to energy-saving and cost-reducing.
The device of described elimination underground Rock And Soil hot stack, the bottom of described inverted well is provided with sedimentation basin 7, blow-off line 8 is provided with inside described sedimentation basin, described blow-off line connects slush pump 9, described mud delivery side of pump connects mud emission pipeline 10, and the outlet of described mud emission pipeline is arranged on the outside of described inverted well.Because mud transition accumulation can make the degree of depth of inverted well reduce, if higher than underground reservoir, then speed of recharging reduces, and underground water can not smooth circulation, therefore arranges slush pump and makes system cloud gray model more reliable to the timely blowdown of inverted well.
Technological means disclosed in the utility model scheme is not limited only to the technological means disclosed in above-described embodiment, also comprises and replaces by above technical characteristic is equivalent arbitrarily the technical scheme formed.Unaccomplished matter of the present utility model, belongs to the common practise of those skilled in the art.
