Abstract
The invention relates to a wastewater-free reverse osmosis purified water machine, wherein five-stage filtration is adopted. According to the wastewater-free reverse osmosis purified water machine, raw water passes through PP cotton, fore-lying active carbon and carbon-rod active carbon or a precise PP cotton filtration core, then enters a resin filtration core, enters a RO membrane through a water inlet electromagnetic valve and a pressurization pump, and is subjected to characteristic dividing through the RO membrane to obtain concentrated water and purified water, a circulation automatic pressure reducing system is additionally arranged on the concentrated water discharge pipe position so as to ensure that the concentrated water and raw water mixture meets the reusing requirement after being uniformly mixed, the circulation system is provided with an electronic component to detect the TDS value of the concentrated water, the combination valve is automatically rinsed so as to achieve purposes of RO membrane service life prolonging and concentrated water emission reducing, and the purified water flows out from the water outlet pipe, flows to rear-laying active carbon through a non-return valve, and is subjected to final filtration through the rear-laying active carbon so as to be drunk by people.
Description
Technical field:
The present invention relates to waste water-free reverse osmosis water purification machine, be specifically related to a kind of water purification machine technical field.
Background technology:
There is the condensed water discharge of larger proportion about existing RO reverse osmosis water purifier commercially, I company research staff develops the RO reverse osmosis purified water system of a new generation for a long time in experience.
RO reverse osmosis water purifier is a kind of different water supply system.Tap water is through PP cotton melt-blown filter, granulated active carbon, extruded activated carbon or accurate PP cotton melt-blown filter pre-treatment (removing chlorine residue in water, most suspended substances, iron rust, colloid, peculiar smell and partial organic substances); enter RO reverse osmosis filter core advanced treatment (remove various impurity remaining in water, comprise the microorganisms such as bacterium, intestinal bacteria, heavy metal and harmful levels of pathogens).When tap water water after RO reverse osmosis filter core is divided into two parts of outflows, a pure water, a condensed water for accounting for 75% for accounting for 25%.Now the pure water of 25% eventually passes the further organics removal of post active carbon, peculiar smell, improving mouthfeel can for directly drinking, the condensed water of other 75% uses being discharged or storing with other large containers (it is great water resource waste that the condensed water of 75% is drained through water drain, if take large container storage use to be very loaded down with trivial details and easily produce the full excessive situation of water).
For the 75% condensed water quantity discharged how reducing RO reverse osmosis water purifier, a national difficult problem at present, my company is in line with leading water-saving and environmental protection science and technology new trend, making healthy water-saving RO water purification machine, scientific and reasonable use water resources, the next generation for us leaves valuable water resources, to the requirement of drinking-water quality, the condensed water quantity discharged of RO reverse osmosis water purifier is dropped to Schwellenwert according to national standard " water for city's residential use quality standard " (GB/T50331-2002).My company is ripe for this technical scheme at present, when working conditions, influent quality meet the service requirements of RO film, my the RO reverse osmosis water purifier effluent quality of new generation of company's research and development meets direct-drinking water standard, and RO film, water pump, complete machine extend 20% than original design work-ing life.
Summary of the invention:
The object of the invention is exactly above deficiency for prior art and provides a kind of waste water-free reverse osmosis water purification machine.
Technical problem to be solved by this invention realizes by the following technical solutions.
Waste water-free reverse osmosis water purification machine, it is characterized in that: tap into the first step 10 turns of 5 microns of PP cottons by former water, the preposition activated charcoal in the second stage, in the cotton filter core of the third stage 5 microns of PP, resin filter element is entered at the fourth stage, in the past topping-up pump is supplied through entering water electromagnetic valve after level Four pre-filtering process, the pressure equilibrium safety when entering petcock and ensureing that RO is molded water, RO is molded mass distributary two-way, one is pure water, water tank is entered or post active carbon can reach adjustment mouthfeel by high-voltage switch gear, tap is drunk at supply pure water, second tunnel condensed water through TDS detector to normally closed wastewater valve, the former water interface of the first step is being connected by reverse checkvalve, reach after the former water of mixing is well mixed in one two three level Four filter flasks and send RO mould to and carry out reverse osmosis,
In order to RO mould output high quality pure water again can condensed water better utilised, after wastewater valve, threeway is installed, be connected to and primaryly apply flexibly on water tap filling a reverse checkvalve, install a dropping valve additional former domestic water former waterborne and ensure that condensed water is as domestic water.
Described before waste water reverse checkvalve, a high-voltage switch gear is installed, with high-voltage switch power supply before post active carbon and with together with, RO machine can be helped to clear up washing action when using domestic water.
The invention has the advantages that: this RO water cleaning systems adopts 6 grades of filtrations, first former water is cotton by PP, preposition activated charcoal, carbon-point gac or the cotton filter core of accurate PP, resin filter element, through entering water electromagnetic valve, topping-up pump enters RO film, condensed water and pure water is become through RO film sub-prime, at condensed water delivery pipe, place installs circulation automatic depressurization system additional, reuse to reach after ensureing condensed water and former water Homogeneous phase mixing, this recycle system is installed detected electronically condensed water TDS value, Automatic-washing combined valve, reach with this and extend RO film and reduce condensed water discharge work-ing life, pure water flow to post active carbon from rising pipe through reverse checkvalve, drink to us altogether filtering for the last time through post active carbon.
Accompanying drawing illustrates:
Fig. 1 is schematic flow sheet of the present invention.
Embodiment:
The technique means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific embodiment, setting forth the present invention further.
Waste water-free reverse osmosis water purification machine shown in composition graphs 1, the first step 10 turns of 5 microns of PP cottons are tapped into by former water, enter the preposition activated charcoal in the second stage enter in the cotton filter cores of the third stage 5 microns of PP with resin filter element, in the past topping-up pump is supplied through entering water electromagnetic valve after level Four pre-filtering process, the pressure equilibrium safety when entering petcock and ensureing that RO is molded water, RO is molded mass distributary two-way, one is pure water, enter post active carbon by high-voltage switch gear and can reach adjustment mouthfeel, tap is drunk at supply water tank or pure water, second tunnel condensed water through TDS detector to normally closed wastewater valve, the former water interface of the first step is being connected by reverse checkvalve, reach after the former water of mixing is well mixed in one two three level Four filter flasks and send RO mould to and carry out reverse osmosis,
