Abstract
The utility model discloses a well water recharge system which comprises a water suction pump and a booster pump. A water outlet of the water suction pump is connected with a water inlet end of a water source heat pump unit through a feed piping and the booster pump. A water inlet end of the water source heat pump unit is connected with a backwater well through a recharge piping. A sediment filter is arranged on the water inlet end of the water source heat pump unit. The arranged sediment filter can filter silt for cooling water sucked from a pumping well high-efficiently, the backwater well losing recharge ability caused by a lot of silt backfilling the backwater well can be avoided, and normal operation of the whole recharge system can be ensured. Furthermore, a frequency converter is used for controlling the operation of the water suction pump, so the water suction pump can work according to practical needs, electric power waste situation can be avoided effectively through frequency conversion and energy saving, and a lot of ground water can be saved at the same time.
Description
Technical field
The utility model relates to a kind of central air-conditioner cooling water recharge system.
Background technology
Groundwater heat pump system, common described well water recharging water source heat pump system is namely extracted underground water out by building pumped well, by secondary heat exchange or directly deliver to water source heat pump units, after extracting heat or release heat, returns underground by recharging well irrigation.Existing well water recharge system is generally a pumped well and three back water wells, the pumped well well head only arranges cyclone desander, the effect of removing sand extreme difference, in use can cause a large amount of silt backfills in back water well, cause back water well to lose water recharge capacity, affect the normal operation of whole well water recharge system.
In the existing well water recharge system, suction pump in the pumped well is according to the maximum water consumption design of unit, in use, even if when air-conditioning system does not need the larger cooling water water yield, suction pump remains that also the water yield of setting carries out work, power consumption is large, and the power wastage phenomenon is serious.
The utility model content
The purpose of this utility model provides a kind of well water recharge system, can carry out to the cooling water that wet well is extracted out high efficiency silt filters, avoid occurring a large amount of silt backfills in back water well and cause back water well to lose water recharge capacity, guarantee the normal operation of whole well water recharge system, can save a large amount of underground water simultaneously.
The utility model adopts following technical proposals:
A kind of well water recharge system, comprise suction pump and relay pump, the delivery port of suction pump is connected the water inlet end of water source heat pump units with relay pump by water supply line, the water side of water source heat pump units connects back water well by recharging pipeline, and the water inlet end of described water source heat pump units is provided with deposition filter.
Also comprise control module and frequency converter, described recharging is provided with temperature collect module in the pipeline, the signal input part of the signal output part link control module of temperature collect module, the signal output part of control module connects the control signal input of frequency converter, and the power output end of frequency converter connects the power input of suction pump.
Described back water well well head is provided with well mouth sealing device.
Described well mouth sealing device adopts flange.
Described back water well periphery is provided with the concrete dense seal.
Be provided with watertight composition between described concrete dense seal bottom and the soil.

The utility model is by arranging deposition filter, can carry out to the cooling water of extracting out from pumped well efficiently that silt filters, and can avoid a large amount of silt backfills in back water well and causes back water well to lose water recharge capacity, guarantees the normal operation of whole well water recharge system; Further, the utility model makes suction pump carry out work according to actual demand by using the work of Frequency Converter Control suction pump, by energy-saving and frequency-variable, has effectively avoided the power wastage phenomenon, can save a large amount of underground water simultaneously.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises the suction pump 1 that is arranged on the pumped well shaft bottom, the delivery port of suction pump 1 is connected the water inlet end that connects deposition filter by pipeline with relay pump, the water side of deposition filter connects the water inlet end of water source heat pump units, and the water side of water source heat pump units connects back water well by recharging pipeline.Owing to having installed deposition filter additional, can carry out to the cooling water of extracting out from pumped well efficiently that silt filters, can avoid a large amount of silt backfills in back water well and cause back water well to lose water recharge capacity, guarantee the normal operation of whole well water recharge system.
The utility model also is provided with control module and frequency converter, recharging of being connected with the water source heat pump units water side is provided with temperature collect module 3 in the pipeline, the signal input part of the signal output part link control module of temperature collect module 3, the signal output part of control module connects the control signal input of frequency converter, and the power output end of frequency converter connects the power input of suction pump 1; Temperature collect module 3 adopts temperature sensor.Temperature sensor can gather and recharge ducted cooling water water temperature after water source heat pump units is carried out heat exchange, and temperature signal transferred to control module, control module is sent to frequency converter with control signal after judging as calculated, frequency converter is selected the water yield of the Current Control suction pump 1 of output suitable frequency, by energy-saving and frequency-variable, effectively avoided the power wastage phenomenon.
Recharge quality in order further to ensure, the well water recharge system adopts closed system, and the back water well well head is provided with well mouth sealing device 2, and well mouth sealing device 2 can adopt flange.The back water well periphery is provided with concrete dense seal 5, is provided with watertight composition 6 between concrete dense seal 5 bottoms and the soil, can prevent effectively that well water is excessive.Because the well water recharge system is closed system, can effectively increase the hydraulic pressure that recharges cooling water, reaches and recharges better effect.
Described deposition filter is ripe existing product, and control module control frequency converter also belongs to ripe prior art, does not repeat them here.
