Description

The water purifier that Double-pressure-relief is ensured

Technical field

The present invention relates to purifier.

Background technology

Water purifier is the equipment for carrying out depth-type filtration, purified treatment to water quality by the use requirement to water, its technological core It is the filter membrane in filter element device, current major technique derives from two kinds of milipore filter and RO reverse osmosis membranes.Water purifier can be filtered effectively Iron rust, sandstone in water removal, colloid, the chemical agent such as chlorine residue, odor, heterochromatic, agricultural chemicals, can also effectively go in water removal in absorption water Bacterium, impurity, toxin, heavy metal etc..Water purification technology in the application of drinking water field, efficiently solve many places due to Harmful minerals is exceeded in underground water and the endemic illness that causes, there is provided health, the water way of safety.Because water purification sets Standby to need just be used after the heavy filtering of raw water, it is slower to go out water speed, needed for being difficult to meet immediately sometimes, therefore all can There is pressure pot to be saved in water side, so that the water deposit that water purifier idle is purified is got up, and pressure pot finite capacity, because This can cut off circuit in good time by installing the interior pressure of electronic high voltage inductive switching bucket, it is to avoid staving, pipeline burst.But only There is potential safety hazard using electronic high voltage switch, if high-voltage switch gear breaks down, whole water purifier will lose safety assurance.

Specific embodiment

In order to be more clearly understood to technical characteristic of the invention, purpose and effect, now compare accompanying drawing and describe in detail Specific embodiment of the invention.

The water purifier that Double-pressure-relief as shown in Figure 1 is ensured, including the water supply conduit of water pump, the water supply conduit are installed On preposition activated charcoal filter 1, PP cottons filter 2, entering water electromagnetic valve 3, RO reverse-osmosis filtering devices 4 are installed, it is described The output end of preposition activated charcoal filter 1 is connected with the PP cottons filter 2, the output end of the PP cottons filter 2 The entering water electromagnetic valve 3, the output of the RO reverse-osmosis filtering devices 4 are installed between the RO reverse-osmosis filtering devices 4 Electronic high voltage is installed on pipeline 5 and switchs 6 and relief valve 7.

In water quality pretreatment system, active carbon filtering device can adsorb the chlorine residue that cannot remove in prime filtering in case Only rear class reverse osmosis membrane receives its oxidative degradation, while also adsorbing the contaminative things such as the small organic molecule come from prime leakage Matter, has obvious Adsorption to act on, also with the work for reducing COD to peculiar smell, colloid and pigment, heavy metal ion etc. in water With, can further reduce RO water inlet SDI values, it is ensured that SDI<5, TOC<2.Oppm.

PP cottons filter 2, using nonpoisonous and tasteless polyester fiber particle, by heating melting, spinneret, traction, receiving The tubulose filter core for shaping and being made.Between its filtering accuracy is from 1um to 300um, the filter core is set without interior axle using interior close outer dredging Meter, can not only maintain flow, pressure differential and the service life of stabilization, while having extremely excellent depth-type filtration effect and pollutant tired Accumulated amount.Because the chemical composition of PP cottons is clean, and meet food sanitation standard, will not be by material to the liquid to be filtered Produce secondary pollution, with flow is big, high precision, corrosion-resistant, high pressure the features such as, be widely used in pure water, food drinking water Prefilter treatment, prefilter treatment of RO machines infiltration etc..PP cottons filter 2 is removed straight more than filter opening by mechanical grading The physical pollution thing in footpath, goes the particulate contamination more than 5 microns in water removal, such as：Suspension, silt, red worm, iron rust, colloid Etc. the material of large volume, the turbidity of water is reduced.

RO is the abbreviation of English Reverse Osmosis, and Chinese means counter-infiltration.The type of flow of general water be by Low concentration flows to high concentration, after water is once pressurize, will from high concentration flow to low concentration, that is, so-called reverse osmosis principle, due to The aperture of its film is 100 a ten thousandths of hairline in RO reverse-osmosis filtering devices 4（0.0001 micron）, general naked eyes cannot See, bacterium, virus are its 5000 times, therefore, only hydrone and part mineral ion can by (ion for passing through without Benefit damages orientation), other impurity and heavy metal are discharged by waste water outlet duct 8.

In certain embodiments, check valve is installed on the output pipe 5 of RO reverse-osmosis filtering devices 4, it is to avoid water countercurrently, The normal operation of guarantee equipment.The output pipe 5 of general RO reverse-osmosis filtering devices 4 is connected to pressure pot and tap, Pressure pot is used for retaining；Tap can also install rearmounted filter directly to use water in the arrival end of tap, general to use Various filter cores such as activated carbon carry out filtration treatment again to water.

In Water treatment, in addition to the increase of water, can also there is hydrogen in pipeline, either water or hydrogen is all A warning amount is had, electronic high voltage switch 6 and relief valve 7 form dual fail-safe, water cleaning systems are closed in time and stops water filtration, Or release hydrogen, unnecessary water, it is to avoid the explosion of pressure pot, pipeline or rearmounted filter core, it is ensured that the use of equipment Life-span, and the waste of water resource is reduced, relief valve 7 is typically using the valve of 5KG ranks.The outlet of wherein relief valve 7 connects Enter the waste water outlet duct 8 of RO reverse-osmosis filtering devices 4, because waste water outlet duct 8 is the intrinsic knot of RO reverse-osmosis filtering devices 4 Structure, the water that relief valve 7 is discharged is processed without separately setting structure, is conducive to simplified system, reduces cost.

The preferred embodiments of the present invention are the foregoing is only, is not intended to limit the invention, for the skill of this area For art personnel, the present invention can have various changes, combination and change.It is all within the spirit and principles in the present invention, made Any modification, equivalent substitution and improvements etc., should be included within scope of the presently claimed invention.
