Abstract
The utility model relates to a purified water production device with a water saving function. The purified water production device comprises a tap water tank, and is characterized in that the tap water tank is connected with a filtering device, the filtering device is connected with a membrane filtering device, the membrane filtering device is connected with a water tank used for storing purified water through a sterilization device, a conduit is connected between a wastewater outlet of the membrane filtering device and the tap water tank, and a valve is arranged on the conduit. The device has the advantages that remained water after membrane filtering can completely return into the tap water tank through the residual pressure of the water production for reuse, and the goals of efficiency and water saving are reached.
Description
Technical field
The utility model relates to a kind of device for producing pure water with water-saving function, is applicable to all take tap water as source water, the production of using the modes such as reverse osmosis method, nanofiltration, ultrafiltration to prepare pure water, water purification.
Background technology
Traditional pure water production technique, synoptic diagram (Figure of description Fig. 1) referring to traditional device for producing pure water: water pump makes tap water enter coarse filtration, fine filtering device carries out primary purifying through promoting, the high-pressure pump that is carried by membrane filter appts again is pressed into membrane filtration system and carries out ultimate purification, at this moment, the moisture that enters membrane filtration system is two-way: one road water enters the preparation water tank in order to can through membrane filtration by sterilization and disinfection.Remaining water was directly discharged through pipeline with waste water formation after another road water then became membrane filtration.The water yield that Yu Shui discharges is about 1:1 with the water yield ratio that enters the preparation water tank, causes so huge water resource waste.
Will why remaining water be discharged with waste water formation behind the membrane filtration? mainly be that ideological understanding has mistaken ideas, assume as a matter of course and think that remaining water is exactly the rubbish that pure water production produces afterwards behind the membrane filtration, can not utilize, can only drain.If collect reuse, also can only be for the production of the various hygiene purposes in the workshop.In fact, remaining water is after coarse filtration, smart filter behind the membrane filtration, and the most of impurity in the water is all removed, returns the city water tank reuse, its quality and not second to tap water, and a large amount of valuable water resourcess are saved again in both environmental protection.
Summary of the invention
The purpose of this utility model is to provide a kind of device for producing pure water with water-saving function, and this device can make the remaining water conservancy behind the membrane filtration all return reuse in the tap water tank with the overbottom pressure of water processed, reaches the purpose of water saving.
Of the present utility model being characterised in that: a kind of device for producing pure water with water-saving function, comprise tap water tank, it is characterized in that: described tap water tank and a filtration unit link, described filtration unit and a membrane filter appts link, described membrane filter appts links through the water tank that sterilizing unit and is used for the storage pure water, be connected with a conduit between the wastewater outlet of described membrane filter appts and the tap water tank, be provided with a valve on the described conduit.
Further, above-mentioned valve is the valve that is in normally open.
Further, above-mentioned filtration unit comprises coarse filter and accurate filter.
Further, the water port of above-mentioned tap water tank is connected with a first row water pipe, is provided with the first valve that is in normally off on the described first row water pipe.
Further, also be connected with a second row water pipe on the conduit between the wastewater outlet of above-mentioned valve and membrane filter appts, be provided with the second valve that is in normally off on the described second row water pipe.
Advantage of the present utility model: need not to change original mode of production, improvement expenses is cheap and simple, convenient, can significantly reduce the contents of residual chlorine in the tap water simultaneously, effectively protects the filtration membrane device, and is easy and simple to handle, safe and reliable.In pure water is produced, to the water-saving rate of manufacture water 〉=more than 99%, basically can reach the effect of zero release.
Description of drawings
Fig. 1 is the organigram of prior art.
Fig. 2 is the organigram of the utility model embodiment.
Among the figure: 1 is tap water tank; 2 is filtration unit; 3 is membrane filter appts; 4 is sterilizing unit; 5 is water tank; 6 is conduit; 8 is the first row water pipe; 7 is the second row water pipe; 61 is valve; 81 is the first valve; 71 is the second valve; 21 is coarse filter; 22 is accurate filter.
Embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, embodiment cited below particularly, and cooperate appended graphic being described in detail below.
With reference to legend, a kind of device for producing pure water with water-saving function, comprise tap water tank 1, it is characterized in that: described tap water tank 1 and a filtration unit 2 link, described filtration unit 2 and a membrane filter appts 3 link, described membrane filter appts 3 links through the water tank 5 that sterilizing unit 4 and is used for the storage pure water, is connected with a conduit 6 between the wastewater outlet of described membrane filter appts 3 and the tap water tank 1, is provided with a valve 61 on the described conduit 6.
Above-mentioned valve 61 is for being in the valve of normally open.
Above-mentioned filtration unit 2 comprises coarse filter 21 and accurate filter 22.
The water port of above-mentioned tap water tank 1 is connected with a first row water pipe 8, is provided with the first valve 81 that is in normally off on the described first row water pipe 8.
Also be connected with a second row water pipe 7 on the conduit 6 between the wastewater outlet of above-mentioned valve 61 and membrane filter appts 3, be provided with the second valve 71 that is in normally off on the described second row water pipe 7.
In the utility model one preferred embodiment, an end of conduit is connected with first row water pipe between the first valve and the tap water tank.
This device is in original technical fitting operation step; as improve shown in the synoptic diagram (referring to Fig. 2) of rear water-saving device for producing pure water: under stopped status; cut off host power supply; water in the emptying tap water tank; water pipe before sawed-off the second valve 71 of difference and the first valve 81; and respectively load onto a three links:link of trade，travel and post accessory and link to each other with sawed-off water pipe; and make two " three ports " relative; water pipe connects and mounted valve 61 between the second valve 71 and the first valve 81, and makes the distance as far as possible close (being about 30cm) of valve 61 and the second valve 71 just finish whole installation sequences of this device.
The production operation step of this device: when start was produced, first Open valve 61 was closed the second valve 71 again, make membrane filtration after remaining water return reuse in the city water tank.When producing shutdown, open first the second valve 71, valve-off 61 again, do not make in the city water tank and flow out.Emphasis in this operation steps: absolute prohibition the second valve 71 is closed simultaneously with valve 61, and this can cause membrane filtration system badly damaged.
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
