Description
Technical Field
The utility model belongs to the technical field of the water purification and specifically relates to a can reduce water purification system of first cup of water TDS value.
Background
The reverse osmosis water purifier is the most common scheme of the existing water purifying equipment. However, the existing reverse osmosis water purifier has the following disadvantages: when the reverse osmosis water purifier stops and stands still, the reverse osmosis membrane is in thick water soaking for a long time, so that water on the raw water side of the reverse osmosis membrane permeates into water on the pure water side, the TDS value of the water on the pure water side is close to that of the raw water side of the reverse osmosis membrane, and after the reverse osmosis water purifier restarts to produce water, the initially produced pure water TDS value (within 2 minutes) greatly exceeds a standard value; secondly, because the reverse osmosis membrane is soaked in the concentrated water for a long time, the service life of the reverse osmosis membrane is greatly shortened due to the fact that the surface of the membrane is easy to be structurally formed.
At present, there is reverse osmosis water purification machine to have increased pure bubble membrane function, replaces the high concentration water in the reverse osmosis filter core through the pure water, makes reverse osmosis water purification machine under the machine-halt state, and the water TDS value of its reverse osmosis membrane raw water side is close with the water TDS value of reverse osmosis membrane pure water side, avoids reverse osmosis membrane to be in the machine-halt state at reverse osmosis water purification machine and the osmosis phenomenon appears. However, the reverse osmosis water purifier that has the pure water bubble membrane function now, when the water of the former water side of replacement reverse osmosis filter core, all extrude the pure water into the RO filter core through water tank and pump by force, will originally save the log raft play water purifier in the former water side of reverse osmosis filter core, and this not only can cause the waste to the water resource, and in addition, very easily leads to the pipeline pressure increase of reverse osmosis water purifier, brings the use risk for the user.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a can effectively reduce the TDS value of the pure water of initial preparation when restarting system water after the long-time standby of water purification system to can retrieve the water purification system of the water of reverse osmosis filter core raw water side.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a water purification system capable of reducing the TDS value of initial water comprises a raw water inlet for raw water to flow in, a concentrated water outlet for concentrated water to discharge and a purified water outlet for purified water to flow out; particularly, the device also comprises a preposed filter group, a pure water bubble membrane tank, a pressurizing assembly, an RO filter core, a postposition filter group and a one-way pressure release valve; the RO filter element is provided with a raw water inlet, a concentrated water outlet and a pure water outlet;
the pure water bubble film tank comprises a shell, wherein an elastically deformable inner container is arranged in the shell, and a water flow channel is arranged between the inner container and the shell; one end of the water flow channel is communicated to the pressurizing assembly, the other end of the water flow channel is respectively communicated to the raw water inlet and the one-way pressure relief valve, and the one-way pressure relief valve is respectively communicated to the concentrated water outlet and the pressurizing assembly;
the water flows along the raw water inlet, the pre-filter group, the water flow channel, the pressurizing assembly, the raw water inlet, the RO filter element, the pure water outlet, the post-filter group and the pure water outlet to form a pure water making path;
the water flow flows along the RO filter element, the concentrated water outlet, the pressurizing assembly and the water flow channel to form an in-core water return flow path;
the water flow flows along the inner container, the raw water inlet and the RO filter element to form a pure water bubble film path;
the water flows along the RO filter element, the pure water outlet and the inner container to form a pure water backflow path;
the water flow flows along the water flow channel, the one-way pressure relief valve and the concentrated water outlet to form a concentrated water pressure relief path;
the water flow flows along the water flow channel, the one-way pressure release valve, the pressurizing assembly and the water flow channel to form a concentrated water inner circulation path.
The principle of the utility model is as follows:
when the water purification system is used for preparing pure water, tap water or other raw water flows into the pre-filter group through the raw water inlet, flows into the water flow channel through the pre-filter group and flows to the RO filter element through the water flow channel. And after being filtered by the RO filter element, most of the purified water flows out through the pure water outlet for users to use, and a small part of the purified water is shunted to the inner container through the pure water backflow path to be stored. The concentrated water produced in the process of preparing pure water is discharged through a concentrated water outlet.
After the user stops getting water, this water purification system can switch to the pure water bubble membrane state. At this time, no external water flows into the water purification system, and no water is discharged to the outside. Pressure boost subassembly action, make the water that stops in the raw water side in the RO filter core flow along the interior water reflux route, the water that stops in the RO filter core is taken out from dense water export, flow into the rivers passageway of pure water bubble membrane jar through pressure boost subassembly in, the extrusion inner bag makes inner bag elastic deformation, make the volume of inner bag change, make this inner bag produce deformation and the volume reduces, extrude the pure water of saving in the inner bag through the volume change of inner bag, flow that switches on through inner bag and raw water entry, the pure water can flow to the raw water side of RO filter core through the raw water entry, occupy because of the water that stops in the raw water side of RO filter core originally is taken out the vacancy that brings. And because inner bag pressurized deformation, the volume of inner bag reduces, the volume that sets up the rivers passageway between shell and inner bag can corresponding increase, can hold more water, guarantee from this that the water that stops in the former water side of RO filter core can all be taken out by pressure boost subassembly, make the pure water of originally saving in the inner bag occupy the whole spaces of the former water side of RO filter core, thereby make reverse osmosis purifier under the standby state, reverse osmosis membrane's both sides are the pure water and soak, the water TDS value of reverse osmosis membrane's both sides is close, even the former water side and the pure water side of RO filter core take place the osmosis phenomenon under water purification system standby state, the water TDS value that also can not lead to the pure water side rises by a wide margin, thereby avoid the problem that water purification system first cup water TDS value exceeds standard after long-time standby.
In the pure water bubble membrane process, if the water quantity stored in the water flow channel is too much, the internal pressure of the pure water bubble membrane tank is greatly increased, and safety hidden troubles are brought to the pure water bubble membrane tank. To this, after the inside water pressure of rivers passageway reached certain pressure value, the water in the rivers passageway can be followed one-way relief valve and flowed, and partial fluid flows along dense water pressure release route, from this water purification system of dense delivery port discharge, makes the water pressure in the rivers passageway descend to the safety range, and at this moment, another part fluid can flow back to the pressure boost subassembly in along the interior circulation path of dense water, flows into rivers passageway again through the pressure boost subassembly to furthest remains the water of taking out from the former water side of RO filter core.
In the pure water film soaking process, the water inlet and the water outlet of the water purification system are closed, for example, a raw water inlet through which raw water flows into the water purification system, a pure water outlet through which pure water flows out of the water purification system, a concentrated water outlet through which concentrated water flows out of the water purification system, and the like, so that the water purification system enters an internal circulation mode, and an external water source cannot flow into the water purification system. After the pure water bubble membrane state is finished, the water pumped out from the raw water side of the RO filter element stays in the water flow channel. When the water purification system produces water for the next time, the water staying in the water flow channel is completely reused and is filtered by the RO filter element to obtain pure water and concentrated water.
Under the pure water bubble membrane state, the water purification system accessible time control or mode control such as TDS value detection originally store the outflow of the pure water in the inner bag, guarantee originally the outflow of the pure water of storing in the inner bag can satisfy in the RO filter core that the water TDS value of raw water side reduces to the setting value can.
Besides the pure water preparation state and the pure water bubble film state, the water purification system can also be provided with a raw water flushing state to flush the film layer according to the requirements of users. The water flow flows along the raw water inlet, the pre-filter group, the water flow channel, the pressurizing assembly, the raw water inlet, the RO filter element, the concentrated water outlet and the concentrated water outlet to form a raw water flushing path.
After the user stops getting water, the water purification system can enter a raw water flushing state. At this time, the pure water outlet stops discharging water. Running water or other raw water flows along the raw water flushing path, flows into the water flow channel through the pre-filter group, flows to the raw water inlet of the RO filter element through the water flow channel, enters the raw water side of the RO filter element, and extrudes the water staying at the raw water side of the RO filter element to the concentrated water outlet for discharge. In the process, the pure water bubble membrane path forms negative pressure due to the action of the pressurizing assembly, and the pure water stored in the liner does not flow into the RO filter element along the pure water bubble membrane path.
The switching of the water purification system among the pure water preparation state, the raw water flushing state and the pure water bubble film state can be realized based on the opening and closing control of a valve, specifically, a first control valve can be arranged between the preposed filter group and the water flow channel, a second control valve can be arranged between the water flow channel and the inlet of the pressurizing assembly, a third control valve can be arranged between the concentrated water outlet and the inlet of the pressurizing assembly, a fourth control valve can be arranged between the outlet of the pressurizing assembly and the raw water inlet, a fifth control valve can be arranged between the concentrated water outlet and the concentrated water outlet, and a sixth control valve can be arranged between the outlet of the pressurizing assembly and the water flow channel. The first control valve, the second control valve, the third control valve, the fourth control valve, the fifth control valve and the sixth control valve can be manually operated or electronically controlled to open or close the valves, so that the working state switching of the water purification system is realized.
The utility model has the advantages of can reduce the first cup of water TDS value that restarts after the water purification system standby, effectively avoid a large amount of pure water to wash the osmotic membrane and lead to the pure water extravagant, accessible pressure release return circuit in time reduces water purification system pipeline pressure, the concentrated water of accessible that rises at pure water bubble membrane in-process, circulation path furthest retrieves because of pressure release return circuit exhaust water.

Based on the above water flow path, the water purification system has three working states, namely a pure water making state, a raw water flushing state and a pure water bubble film state.
When the water purification system is in a pure water production state, the raw water inlet 1 is opened, the pure water outlet 8 is opened, the first control valve 15 is opened, the second control valve 16 is opened, the third control valve 17 is closed, the fourth control valve 18 is opened, the fifth control valve 22 is opened, and the sixth control valve 19 is closed, at this time, tap water flows into the pre-filter group 2 from the raw water inlet 1 through the pressure reducing valve 26, flows into the water flow channel 14 through the first control valve 15, then flows into the pressurizing inlet 24 of the pressurizing pump 4 through the second control valve 16, and flows into the fourth control valve 18 from the pressurizing outlet 25. After passing through the fourth control valve 18, the water flows into the RO cartridge 5 through the raw water inlet 9. After being filtered by the RO filter element 5, most of the purified water flows to the post-filter unit 6 through the purified water outlet 11 and the third check valve 23, and flows out from the purified water outlet 8 for the user to use after being filtered by the post-filter unit 6, and a small part of the purified water is shunted through the purified water backflow path, flows to the inner container 13 from the purified water outlet 11 and is stored in the inner container 13. The concentrated water generated in the filtering process flows to the fifth control valve 22 through the concentrated water outlet 10 and is then discharged from the concentrated water outlet 7.
When the water purification system is in a raw water flushing state, the raw water inlet 1 is opened, the purified water outlet 8 is closed, the first control valve 15 is opened, the second control valve 16 is opened, the third control valve 17 is closed, the fourth control valve 18 is opened, the fifth control valve 22 is opened, and the sixth control valve 19 is closed, at this time, tap water flows into the pre-filter group 2 from the raw water inlet 1 through the pressure reducing valve 26, flows into the water flow passage 14 through the first control valve 15, then flows into the pressurizing inlet 24 of the pressurizing pump 4 through the second control valve 16, and flows into the fourth control valve 18 from the pressurizing outlet 25. After passing through the fourth control valve 18, the water flows into the RO cartridge through the raw water inlet 9. Since the pure water outlet 8 is closed, the RO filter element 5 does not filter pure water, and tap water flowing into the RO filter element 5 washes the raw water side of the reverse osmosis membrane, flows to the fifth control valve 22 through the concentrated water outlet 10, and is then discharged from the concentrated water outlet 7. This washing process's effect lies in the water that the discharge stayed in 5 former water sides of RO filter core, and clean reverse osmosis membrane and tentatively reduce the water TDS value of 5 former water sides of RO filter core.
When the water purification system is in a pure water bubble membrane state, the raw water inlet 1 is closed, the pure water outlet 8 is closed, the first control valve 15 is closed, the second control valve 16 is closed, the third control valve 17 is opened, the fourth control valve 18 is closed, the fifth control valve 22 is closed, the sixth control valve 19 is opened, at the moment, the booster pump 4 acts, so that the water staying at the raw water side in the RO filter element 5 flows along the core water return path, the water staying in the RO filter element 5 is pumped out from the concentrated water outlet 10, flows to the booster pump through the third control valve 17, then flows to the sixth control valve 19 through the booster outlet 25 and finally flows into the water flow channel 14 of the pure water bubble membrane tank 3, at the same time, the inner container 13 of the pure water bubble membrane tank 3 is deformed by the water in the water flow passage 14, and the pure water stored in the inner container 13 is extruded from the inner container 13, flows to the raw water inlet 9 through the first check valve 20, and further flows into the raw water side of the RO filter element 5. The water flowing to the raw water side of the RO filter element 5 flows out from the concentrated water outlet and returns to the water flow channel 14 of the pure water bubble membrane tank 3 through the pressurization effect of the booster pump 4.
In the above-mentioned in-process, the pure water of depositing in inner bag 13 originally can replace the water that stays in the 5 former water sides of RO filter core gradually, makes the water TDS value of the raw water side reduce in the RO filter core 5, makes the water TDS value of the raw water side in the RO filter core 5 and the water TDS value of the 5 pure water sides of RO filter core tend to be close, has avoided water purification system under the standby state, and the former water side and the pure water side of RO filter core 5 appear the osmosis phenomenon and lead to the water TDS value of pure water side to rise by a wide margin. When the water purification system is switched from the pure water bubble membrane state to the pure water making state, most of water in the core water return flow path, the pure water bubble membrane path and the inner container 13 enters the RO filter element 5 again through the raw water inlet 9 for filtration and reuse.
In the above process, after the internal water pressure of the water flow channel 14 reaches a certain pressure value, the water in the water flow channel 14 can flow out from the one-way pressure release valve 28, a part of the fluid flows along the concentrate pressure release path, and is discharged from the water purification system through the concentrate water outlet 7, so that the water pressure in the water flow channel 14 falls within a safe range, at this time, as the internal water pressure of the water flow channel 14 decreases, the other part of the fluid can flow back into the booster pump 4 along the concentrate circulation path, and flows into the water flow channel 14 again through the booster pump 4, thereby maximally retaining the water extracted from the raw water side of the RO filter element 5.
The preferred embodiment of the present invention is only listed in the present specification, and all the technical changes equivalent to those made under the working principle and thought of the present invention are considered as the protection scope of the present invention.
