Abstract
The utility model relates to a recharging type underground water ground-source heat pump device, in particular to a unidirectional open type tail water recharging device of the underground water ground-source heat pump, which can greatly improves the recharge rate of tail water. The device comprises a water outlet well, a water pump, a water inlet pipe, a refrigerating and heating machinery room, a return pipe and a recharging well, wherein a well cover is added on the recharging well, and a one-way exhaust valve is arranged on the well cover of the recharging well. The device can introduce air which is generated in the recharging device into atmosphere, can effectively eliminate the main inducements which cause the rapid attenuation of the tail water recharge rate of the underground water ground-source heat pump system and even the failure of the recharging system, can greatly improve the rail water recharge rate and can create necessary conditions for the 100% recharge rate, thereby preventing the problems of underground water body damaging, environment pollution, heat pollution and the like due to geothermal surplus water, and simultaneously the device is beneficial to maintain the reservoir pressure and prolongs the service life of thermal fields.
Description
Technical field:
The utility model relates to and recharges formula underground water earth source heat pump device, especially a kind of unidirectional open tail water backflow device of underground water earth source heat pump that can increase substantially the tail water recharge rate.
Background technology:
Known underground water earth source heat pump refrigeration and heating system are divided into two classes, and a class is a single flow underground water earth-source hot-pump system, and a class is to recharge formula underground water earth-source hot-pump system.Because single flow underground water earth-source hot-pump system has only pumped well, there is not inverted well, underground water behind the heat-obtaining directly enters surface water body, not only surface drainage and soil are polluted, and heavy damage groundwater resources, therefore present underground water earth-source hot-pump system seldom uses direct air system, and most the employing recharged formula underground water earth-source hot-pump system.But the underground water earth-source hot-pump system tail water actual average recharge rate of operation is very low at present.The main reason that causes underground heat tail water water recharge capacity to descend is the blockage problem of inverted well, and the reason that inverted well stops up is except because the suspended particle that contains in the water, attached to recharging on the borehole wall or entering in the crack of heat storage and influence outside the water recharge capacity, the bubble in the recharge water also is to influence to recharge one of principal element of speed under the effect of recharging pressure.So resolving tail water recharge system bubble obstructing problem is the important prerequisite that realizes that underground water earth-source hot-pump system tail water 100% recharges.But at present domestic do not have good solution as yet to this problem, thereby limited the further raising of tail water recharge rate technically.
Summary of the invention:
The purpose of this utility model aims to provide the unidirectional open tail water backflow device of a kind of underground water earth source heat pump, to solve underground water earth-source hot-pump system tail water recharge system bubble obstructing problem, effectively eliminate and cause the major incentive that underground water earth-source hot-pump system tail water recharge rate is decayed rapidly even recharge system lost efficacy, increase substantially the tail water recharge rate, recharge the creation necessary condition for realizing 100% tail water.
The technical solution adopted in the utility model is: the unidirectional open tail water backflow device of a kind of underground water earth source heat pump, comprise wet well, water pump, water inlet pipe, cooling and warming machine room, return pipe, inverted well, described inverted well adds well lid, and this inverted well covers and is provided with one-way exhaust valve.Can in time the gas that produces in the inverted well be entered in the atmosphere by this one-way exhaust valve, thereby effectively prevent the recharge system vent plug.
The utility model is compared with original closed tail water backflow device, its beneficial effect is: the technical scheme of introducing atmosphere by the gas unidirectional that will produce in the backflow device, effectively eliminate and cause the major incentive that underground water earth-source hot-pump system tail water recharge rate is decayed rapidly even recharge system lost efficacy, increase substantially the tail water recharge rate, for realizing that 100% tail water recharges the creation necessary condition, thereby problems such as the body of groundwater destruction of avoiding underground heat to abandon water causing, environmental pollution, thermal pollution, help keeping reservoir pressure simultaneously, prolong the hot field life-span.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure: water pump 1, wet well 2, outdoor natural terrace 3, water outlet well lid 4, water inlet pipe 5, central air-conditioning cooling and warming machine room 6, return pipe 7 recharges well lid 8, one-way exhaust valve 9, inverted well 10.
The specific embodiment:
The utility model is described in further detail below in conjunction with drawings and Examples.
The unidirectional open tail water backflow device of the described underground water earth source heat pump of present embodiment, its wet well 2, inverted well 10 settings separated by a distance add water outlet well lid 4 respectively and recharge well lid 8; Water pump 1 can be that immersible pump places wet well 2 bottom well water, and well water is introduced central air-conditioning cooling and warming machine room 6 by water inlet pipe 5; The anti-mouth of tail water row of central air-conditioning cooling and warming machine room 6 is introduced in the inverted wells 10 by return pipe 7; Recharge well lid 8 and be provided with one-way exhaust valve 9.When the pressure of the gas that produces when recharge system surpassed atmospheric pressure, described single-way gas-discharge valve 9 started, and unnecessary gas in the system is introduced atmosphere.
