Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly
Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of the present invention rather than complete
The embodiment in portion.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creativeness
The every other embodiment obtained under work premise, broadly falls into the scope of protection of the invention.
As it is shown in figure 1, present invention is disclosed a kind of surface water water source heat pump central air-conditioning system diafiltration water intaking dress
Putting, including outdoor water intaking part and indoor water intaking part, key point and the improvement of the present invention are outdoor
Water intaking part, there is no much differences between indoor water intaking part and end air conditioning part and prior art,
Owing to indoor water intaking partly belongs to prior art, in technical scheme and being not shown in the drawings.
Outdoor water intaking part includes at least one water intake well 1, and the heat pump central air conditioner of the present invention is provided with 6 mouthfuls and takes
Well-water supplies, owing to the architectural feature of every mouthful of water intake well is consistent, therefore only to a bite therein in the present embodiment
Well is described in detail；Water intake well 1 choosing is built in applicable bank or Ha Noi, currently preferred, water intaking
Well 1 is built in bank, hole diameter, well depth according to on-the-spot physical condition (water yield etc. as on-the-spot) and the scale of water intaking (as
The water yield needed for indoor water intaking) depending on, shaft bottom is embedded under stratum, riverbed at least 3 through loosely-packed layer by well body
Rice, the borehole wall of water intake well is welded, at water intake well by spiral steel pipe 2, bridge-type percolating pipe 4 and precipitation tube 5
Bottom and the surrounding of water intake well fill for the gravel 3 at diafiltration water source, wherein, the thickness of the gravel 3 filled
Degree is 15-50cm.
Preferably, bridge-type percolating pipe 4 is located at the position that water source flow in water intake well is big, its a length of 7-10m,
Water source is fetched water into interior, due to by gravel 3 by flowing into after gravel 3 diafiltration around bridge-type percolating pipe 4
Diafiltration flows in water intake well the silt of the trace that can adulterate, and therefore the lower end weld length at bridge-type percolating pipe 4 is 3
The precipitation tube 5 of rice, for precipitating the silt in water intake well.
Being provided with the immersible pump 6 for extracting water source in described water intake well, the dynamic water of water intake well is located at by this immersible pump 6
At Wei, i.e. the centre position of bridge-type percolating pipe 4 is on the lower side, being arranged over for extracting water intake well at water intake well
Interior precipitated silt sludge pump 7, when the sediment deposition in water intake well to immersible pump position, in water intake well
Putting into a flexible pipe, a termination sludge pump of flexible pipe, the other end accesses at the mud in well, by water intake well
Interior mud is discharged outside well, it is ensured that the diafiltration water source in water intake well is normally for indoor water intaking.
The method of surface water water source heat pump central air-conditioning system diafiltration water intaking, comprises the steps:
Water intake well choosing is built in applicable bank or Ha Noi, and hole diameter, well depth are according to on-the-spot physical condition and water intaking rule
Depending on mould, at least 3 meters of the stratum, embedding riverbed, shaft bottom of water intake well, the water intake well of the present invention is preferred, and choosing is built
In river bank, in the well accomplished fluently, put into steel thimble as retaining wall, after the degree of depth of well reaches requirement, in shaft bottom
Interior filling gravel, the thickness of the gravel in shaft bottom at least 20cm；By the spiral steel pipe welded, bridge-type diafiltration
Pipe, precipitation tube put into the center position of steel thimble, spiral steel pipe, bridge-type as the borehole wall of diafiltration water intake well
The diameter of percolating pipe and precipitation tube is less than the diameter of steel thimble, and bridge-type percolating pipe is located at the middle section position of water intake well
As the diafiltration use at water source, the lower section of bridge-type percolating pipe is located at by precipitation tube, is used for precipitating water source trace silt；
Filling gravel between the inwall and the outer wall of diafiltration water intake well of steel thimble, filled gravel thickness is
Behind the position of the weld upwards 30cm of 15-50cm, gravel pack to bridge-type diafiltration water pipe and serpentine pipe, then
Firm sleeve pipe is taken out；At the dynamic water level of water intake well, (i.e. lower position in bridge-type percolating pipe) is installed and is used for
The immersible pump at extraction water source, the water source in water intake well is by the gravel around bridge-type percolating pipe and bridge-type percolating pipe
After diafiltration, at immersible pump extraction to indoor water intaking, heat pump central air-conditioning uses.
The above-mentioned a length of 7-10m of bridge-type percolating pipe, a length of 3 meters of precipitation tube.
For the ease of to fetch water into maintenance, above water intake well, build an inspection-pit, in inspection-pit
Sludge pump is installed, when the position of the sludge settling in water intake well to immersible pump, in water intake well, puts into one
The sebific duct that root is connected with sludge pump, discharges the mud in well outside well, and the effect of inspection-pit is conveniently to work
Personnel overhaul entering interior equipment, as immersible pump is out of order, or need to recoil in water intake well
Wash, in order to prevent rainwater or other from polluting object and flowing in water intake well, therefore pacify above inspection-pit
Fill a fluid pressure type closing door.
The diafiltration intake technology of the present invention solves for the vile weather impact on water source water temperature, take riverbed with
Under diafiltration water source, water temperature have also been obtained constant, boisterous is not affected by the summer in winter.Answering of this technology
With, thoroughly break that surface water water source heat pump central air-conditioning system is the most energy-conservation or vile weather has needed to assist cold
The saying of thermal source, it provides the stable water yield, water temperature and water quality for unit equipment, thus improves unit
Efficiency and service life, save the equipment such as unit and pipeline, the cleaning maintenance of water system, maintenance etc. numerous
Trivial manage after sale work.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all at this
Within bright spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in this
Within bright protection domain.
