Description
Technical field
The water supply well that the utility model relates to water-source heat-pump central air conditioner technical field recharges problem, especially a kind of water-source heat-pump central air conditioner with well go out, the cone-shaped seal structure of water recovery apparatus.
Background technology
Water-source heat-pump central air conditioner, be taking temperature all the year round constant underground water as medium, by source pump, improve or reduce water temperature and reach refrigeration, heat object, for building provides the central air-conditioning of cold and heat source.Because its Energy Efficiency Ratio is high, than other traditional form central air-conditioning energy 40～60%, energy conservation and consumption reduction effects significantly and is progressively subject to the favor of government, office, business unit, has reached most user's accreditation simultaneously.At present, the return water mode of having implemented to install water-source heat-pump central air conditioner all adopts " many wells recharge " mode.Draw water from a bite water supply well, the heat exchanger by heat pump main frame after the cold in water or heat are taken away is discharged water, recharges to more than two mouthfuls or two mouthfuls water supply wells.This mode advantage is that Energy Efficiency Ratio is high, but exists the water of discharging all to recharge in time to underground problem.First, because backwater is naturally to trickle without pressure in well head open type, not only back-flow velocity is slow, and easily causes backwater to pollute.And cannot get back in time underground water, can overflow or directly be disposed to ground by pipeline from well head.Long-term discharge, not only causes the waste of water resource, also may cause level of ground water to decline even exhausted, and then has influence on the safety of surrounding building; Secondly, the well number that need to beat is more, and the land area that need take is large, in the less groups of building of floor space (thing), cannot use.The above-mentioned shortcoming of " many wells recharge " mode, the power savings advantages of water-source heat-pump central air conditioner is cancelled, being to promote at water-source heat-pump central air conditioner, implementing to save energy and reduce the cost, improve a bottleneck problem in the process of environment, is also the behavior that national hydraulic department is strictly forbidden.
Due to its drawback large area manifest, be mainly manifested in the underground water of taking and can not accomplish that 100% all recharges to underground, then discharge earthward, cause that thermal source well silts up, water level declines.This mode in " taking " underground water temperature, also " uses " underground water, caused valuable water resource to waste greatly, make water-source heat-pump central air conditioner paralyse because of the anhydrous available whole system that causes simultaneously.Therefore.The shortcoming of " many wells recharge " mode becomes the bottleneck that water-source heat-pump central air conditioner is promoted and developed.
Summary of the invention
The purpose of this utility model is the defect in order to overcome " many wells recharge " completely, provide that a kind of same well goes out, the flat hermetically-sealed construction of water recovery apparatus, solve the problem that thermal source well silts up, water level declines, backwater energy 100% is all recharged to underground, can make leaving water temperature remain at suitable temperature simultaneously.
For achieving the above object, the utility model adopts following technical scheme: a kind of water-source heat-pump central air conditioner with well go out, the cone-shaped seal structure of water recovery apparatus, comprise a support water-permeable pipe that is sleeved on water supply well inner side, support water-permeable pipe and comprise n+1 permeable section and n supporting section, permeable section is alternately distributed with supporting section; Be fixed with respectively n bellmouth at n supporting section madial wall, n >=1 and be integer; In this support water-permeable pipe, be provided with outlet pipe and return pipe simultaneously; Outlet pipe arranged outside heat insulation structural is also fixed with n tapered piston; A described n tapered piston mates respectively pressing with n bellmouth and is sealed n separation layer of formation; The water inlet of described outlet pipe gos deep into the downside of n separation layer, and the delivery port of each return pipe lays respectively in the backwater space of n separation layer upside.Outlet pipe arranged outside heat insulation structural is at outlet pipe arranged outside thermal insulation layer, and is fixed with n tapered piston in outlet pipe outside; Or outlet pipe is set to compound outlet pipe, be set with the outlet pipe sleeve pipe of matched in clearance in outlet pipe outside, be fixed with n tapered piston in the outside of outlet pipe sleeve pipe.Between described outlet pipe and outlet pipe sleeve pipe, be air heat-insulation layer, or in interlayer between outlet pipe and outlet pipe sleeve pipe, pour into heat-barrier material and form thermal insulation layer.The quantity of described return pipe is n, and the delivery port of each return pipe lays respectively in the backwater space of n separation layer upside; Or the quantity of return pipe is not more than n, same return pipe has delivery port at adjacent backwater spatial placement.On the interface between any a pair of tapered piston and bellmouth, be respectively arranged with flexible seal layer.
The beneficial effects of the utility model are:
1. the utility model utilizes the tapered piston and the bellmouth composition backwater spaces of organizing separation layer and independent sealing of supporting on water-permeable pipe on outlet pipe sleeve pipe more, thereby can make return pipe be pressed into respectively in different backwater spaces, reaches many backwater path objects.Make to realize in same well water outlet, the backwater of equivalent, and utilize soil to carry out sufficient heat exchange.Because underground water seals, recycles in overall process, can not cause any pollution to underground water, really accomplish the temperature of " taking " underground water only and " use " groundwater resources are not achieved environmental protection, cycles, economized economy.
2. the utility model reasonable in design, utilizes the deadweight of outlet pipe sleeve pipe, can make tapered piston and bellmouth be combined to form stable confining bed.
3. in backwater and outlet pipe tube wall contact process, not with the heat exchange that water generates is new that goes out that reaches initial leaving water temperature, thereby can significantly improve water source heat pump units efficiency.
4. the utility model can all be recharged the water of extraction to underground, has accomplished veritably the heat of " utilization " underground water only and cold and does not waste valuable groundwater resources.With respect to the mode such as " underground pipe ", " many wells recharge ", greatly reduce floor space, ensure that level of ground water is normal, and can not affect the basis of building, make the narrow and small place of area also can adopt energy-conservation water-source heat-pump central air conditioner.
5. the utility model reasonable in design, guarantees that individual well can complete whole backwater tasks.By means of annular permeable layer and soil horizon, reduce backwater flowing velocity, so that high backwater and the stratum of temperature fully carries out, after heat exchange, backwater is being summarized in to underground water, finally reach the object of same well water resources circulation.Thereby avoid the waste of water resource, avoid level of ground water because of the mobile even exhaustion that declines, guarantee that subsurface structure is stablized and the safety of surrounding building.
