Description
技术领域technical field
本实用新型涉及浓水回收技术领域，更具体地说，涉及一种具有浓水回收功能的净水机。The utility model relates to the technical field of concentrated water recovery, in particular to a water purifier with the function of concentrated water recovery.
背景技术Background technique
伴随水源的污染，净水机逐渐被广泛应用。净水机利用反渗透原理对水进行净化，将净化后符合标准的纯水输出供用户使用，同时排出浓水(不符合标准的水)。由于浓水与纯水的体积比较大，导致水资源的利用率较低。With the pollution of water sources, water purifiers are gradually being widely used. The water purifier uses the principle of reverse osmosis to purify water, and outputs purified water that meets the standard for users to use, while discharging concentrated water (water that does not meet the standard). Due to the large volume ratio of concentrated water and pure water, the utilization rate of water resources is low.
为了提高水资源利用率，需要减小浓水与纯水的体积比，浓水回收是主要手段。目前，净水机将经过反渗透处理的浓水进行第二次反渗透处理，达到浓水回收的目的。反渗透处理过程中，浓水中的一些离子或者杂质处于过饱和状态时会析出，析出的离子和杂质会堵塞反渗透滤芯，导致反渗透滤芯的使用寿命衰减。由于第二次反渗透处理的反渗透滤芯衰减速度比第一次反渗透处理的反渗透滤芯衰减速度快，导致整个净水机的反渗透滤芯使用寿命存在不一致的情况，即反渗透滤芯使用寿命的一致性较低，使得净水机的维护成本较高。In order to improve the utilization rate of water resources, it is necessary to reduce the volume ratio of concentrated water to pure water, and concentrated water recovery is the main means. At present, the water purifier performs the second reverse osmosis treatment on the concentrated water treated by reverse osmosis to achieve the purpose of concentrated water recovery. During the reverse osmosis treatment process, some ions or impurities in the concentrated water will be precipitated when they are in a supersaturated state, and the precipitated ions and impurities will block the reverse osmosis filter element, resulting in attenuation of the service life of the reverse osmosis filter element. Since the attenuation rate of the reverse osmosis filter element of the second reverse osmosis treatment is faster than that of the first reverse osmosis treatment, the service life of the reverse osmosis filter element of the entire water purifier is inconsistent, that is, the service life of the reverse osmosis filter element The consistency is low, making the maintenance cost of the water purifier higher.
综上所述，如何回收浓水，以提高净水机中反渗透滤芯使用寿命的一致性，降低净水机的维护成本，是目前本领域技术人员亟待解决的问题。To sum up, how to recover concentrated water to improve the service life consistency of the reverse osmosis filter element in the water purifier and reduce the maintenance cost of the water purifier is an urgent problem to be solved by those skilled in the art.

Preferably, the pre-filter element includes: a PP cotton filter element 2 , a granular carbon filter element 4 and a carbon rod filter element 5 connected in sequence. The rear filter element 18 is an activated carbon filter element or a composite filter element composed of an activated carbon filter element and ultrafiltration. It can be understood that the PP cotton filter element 2 , the granular carbon filter element 4 and the carbon rod filter element 5 are distributed sequentially along the flow of water. Of course, the pre-filter element and the post-filter element 18 can also be selected as other filter elements, and are not limited thereto. It should be noted that PP cotton is commonly known as doll cotton, hollow cotton, and filling cotton.
为了控制压力，优先选择在PP棉滤芯2和颗粒炭滤芯4之间串接低压开关3，便于控制压力。当然，也可选择低压开关3位于颗粒炭滤芯4和碳棒滤芯5之间。In order to control the pressure, it is preferred to connect the low-pressure switch 3 in series between the PP cotton filter element 2 and the granular carbon filter element 4 to facilitate pressure control. Of course, the low pressure switch 3 can also be selected to be located between the granular carbon filter element 4 and the carbon rod filter element 5 .
上述实施例提供的具有浓水回收功能的净水机中，前置滤芯的进口与自来水等待净化的水源连通。具体的，前置滤芯的进口通过管道以及三通球阀1与自来水管连通。后置滤芯18通过输送管输送至用户使用处，具体的，输送管上具有出水龙头19。优选的，出水龙头19为鹅颈龙头。In the water purifier with concentrated water recovery function provided by the above embodiment, the inlet of the pre-filter element is connected with the tap water waiting to be purified. Specifically, the inlet of the pre-filter element communicates with the tap water pipe through the pipeline and the three-way ball valve 1 . The rear filter element 18 is transported to the place of use by the user through a delivery pipe. Specifically, the delivery pipe has a water outlet tap 19 . Preferably, the outlet faucet 19 is a gooseneck faucet.
