Description

A kind of water purifier and method reducing pure water TDS value
Technical field
The invention belongs to purifier technical field, in particular to a kind of water purifier and method for reducing pure water TDS value.
Background technique
Traditional reverse osmosis water purifier, water-making ability are usually daily 50 gallons, and water-making ability adds from 400 gallons to 800 Logical sequence or even 1000 add logical sequence and be commonly referred to as big flux water purifier, big flux water purifier is also being defended while improving certain performances New problem is brought in terms of raw index and cost performance, produces " Su Shui " problem.
The pipelined channel of reverse osmosis membrane filter element (RO filter core) is all such as flowering structure at present: raw water enters from one end of filter core, Raw water filters from outside to inside, and filtered pure water is gone out by central tube, and filtered concentrated water is in the outside of central tube.Reverse osmosis The concentrated water of diafiltration core concentrated water side, ion, the organic matter of contained high concentration can be slowly diffused into pure water side, if the time Long enough can make the concentration of two sides reach balance.If passing through the diffusion at a night, the TDS value of pure water will in pure water side Apparent increase, if heavy metal ion is more in raw water, the heavy metal in pure water also can be exceeded, and water quality, mouthfeel all can be big It is impacted.
At work, the TDS at pure water end is in normal condition to big flux water purifier, and user's RO film when stopping using is intake The concentrated water at end can be gradually diffused into pure water end, and the time of diffusion started to show at 5 minutes or more, the general root of the water at pure water end Depending on the size of putamina, 500-1000ml or so is generally had, also results in restarting first glass of water TDS value after work It is higher.
Summary of the invention
It is pure the purpose of the invention is to provide a kind of reduction for being able to solve first glass of higher problem of water TDS value of big flux The water purifier and method of water TDS value.
For this purpose, first technical solution of the invention is: a kind of water purifier reducing pure water TDS value, including fuselage and interior The plate of water route of default pipeline is set, plate of water route is equipped with original water inlet, pure water outlet and concentrated water outlet;It is equipped in the plate of water route Booster pump, the first inlet water solenoid valve and the first RO filter core, booster pump are connected to the first RO filter core by the first inlet water solenoid valve Water inlet end, the pure water end of the first RO filter core are connected to pure water outlet by the first non-return valve, high-voltage switch gear, the first RO filter core it is dense Water end (W.E.) is connected to concentrated water outlet by concentrated water solenoid valve;
It is front filter element outside composite filter element it is characterized by: being also equipped with composite filter element in the plate of water route, inside is second RO filter core, the two are separated by a pipe;The composite filter element is equipped with front filter element import, front filter element outlet, the 2nd RO Filter core import, the 2nd RO filter core pure water outlet and the outlet of the 2nd RO filter core concentrated water, the 2nd RO filter core concentrated water outlet with it is preposition Filter cartridge outlet is connected;The original water inlet is connected to booster pump by the front filter element outside composite filter element, and booster pump passes through Second inlet water solenoid valve is connected to the 2nd RO filter core import, and the 2nd RO filter core pure water outlet is connected to first by the second non-return valve The water inlet end of RO filter core;It is additionally provided with control module in the fuselage, control module controls the first inlet water solenoid valve, booster pump and the The on-off of two inlet water solenoid valves.
Preferably, the 2nd RO filter core concentrated water exit is equipped with third non-return valve, and the 2nd RO filter core concentrated water exports Place is equipped with metering hole.
Preferably, when first inlet water solenoid valve is in running order, the water inlet end of the first RO filter core be connected to raw water into Mouthful;When second inlet water solenoid valve is in running order, the 2nd RO filter core inlet communication original water inlet, the 2nd RO filter core pure water Outlet is connected with the water inlet end of the first RO filter core.
Preferably, the working condition of first inlet water solenoid valve and the second inlet water solenoid valve is mutually staggered, i.e., first into When water solenoid valve is in running order, the second inlet water solenoid valve is that off working state or the second inlet water solenoid valve are in work When state, the first inlet water solenoid valve is off working state.
Preferably, the composite filter element further includes that filter flask, filter flask lid, turntable, platen and RO filter core lid, front filter element are placed in In filter flask, pipe is placed inside front filter element, the 2nd RO filter core is placed in pipe, and pipe and RO filter core lid match;The pressure Disk is matched with turntable, is placed in filter flask lid.
Preferably, the platen towards filter flask side be equipped with multilayer cyclic structure, with front filter element, the 2nd RO filter core into Water outlet matches, and the platen other side is set there are four through-hole, sets that there are four water flowing columns on turntable, is equipped between platen and turntable close Gasket;The turntable can be rotated relative to platen, be connected there are the through-hole of platen with water flowing column in rotation process and disconnected company Logical two states.
Second technical solution of the invention is: a method of pure water TDS value being reduced, using above-mentioned water purifier, just When normal water processed, the first inlet water solenoid valve is opened, and the normal water processed of the first RO filter core, the second inlet water solenoid valve is in off state at this time; When stopping water processed, the first inlet water solenoid valve is closed, and the second inlet water solenoid valve is opened, and the 2nd RO filter core in composite filter element is normally made Water, the pure water of generation enters the water inlet end of the first RO filter core by the second non-return valve, so that the first RO filter core is replaced using pure water Concentrated water in filter core after concentrated water is discharged, closes booster pump, the second inlet water solenoid valve, while the concentrated water that the 2nd RO filter core generates It is back to before booster pump and is mixed into the 2nd RO filter core with raw water.
Due to the problems of liquid flow of booster pump, the first inlet water solenoid valve is closed, in the case that the second inlet water solenoid valve is opened, work It is too big to make pressure, metering hole need to be set or increases flow-limiting valve, the size of metering hole makes composite filter depending on the flow of booster pump 2nd RO filter core operating pressure of in-core is adjusted to normal working range.
The present invention increases the 2nd RO filter core an of low capacity on the basis of traditional big flux water purifier, and will be preposition Filter core and the 2nd RO filter core form composite filter element, avoid increasing RO filter core and lead to that fuselage is excessive, cost abruptly increase.? After shutdown, the concentrated water in the first RO filter core of displacement is gone using the pure water that the 2nd RO filter core generates, so that the concentrated water of the first RO filter core All become pure water in end, solves ion diffusion problem, increase the TDS of pure water in pure water end will not, solve in this way The higher problem of certainly big first glass of water TDS value of flux.
