Description

Two films do not have waste water reverse osmosis purified water machine

Technical field

The utility model relates to a kind of water-purifying machine, and referring in particular to two films does not have waste water reverse osmosis purified water machine.

Background technology

Reverse osmosis is a kind of membrane separation technique that the nineties grows up, and it mainly utilizes the penetration theory of semi-permeable membranes, gives by certain mode that pre-it is a kind of anti-in the power of naturally osmotic direction, and the water in the strong solution is permeated in dilute solution.The device of being made up of the reverse osmosis element is a reverse osmosis equipment.Utilize Reverse Osmosis Technology that water is further handled, can remove radioelement and various mineral ions such as turbidity in the water, colourity, hardness, radium, uranium, chemical substances such as metal ions such as particularly harmful arsenic, copper, cadmium, barium, chromium, lead, mercury, manganese and prussiate, fluorochemical, it is pure that water is returned to.

But existing purified water machine consumes regretting than multi-source water because aspects such as material, technology can't solve in the pure water manufacturing processed.China is a country that Freshwater resources are very deficient, has made full use of water resources, has become a new problem of China's economy and social sustainable development.Water saving has been each department, unit, the responsibilities and obligations that each citizen should use up.Call the theory of being based on practising strict economy and cutting the waste for active response country " energy-saving and emission-reduction ".For this reason, I utilize nearly year through the principle of work and the process for preparing water of careful research purified water machine, through experiment many times, have researched and developed the energy-saving purified water machine of a new generation's " two films do not have waste water ".Detect in real time through the omnidistance control of intelligence control system (time is adjustable), transmitter, control waste water makes the TDS value reach the pure water quality, and the RO film is not caused any harm, and makes the water reuse rate rise to (former water TDS value is below 600) more than 95% simultaneously.It has overcome 1: 4 discharge of wastewater defective of traditional RO water purification machine, realize brand-new integrated structure design healthy and economic, energy-conservation and that environmental protection is achieved many things at one stroke, more reliable product performance have been guaranteed, more environment for use is provided, annotated the harmony of RO purified water machine and health of people, greatly reducing the water producing cost of purified water machine, is a scientific and technological achievement of benefiting the nation and the people, and also is the revolution on the purified water machine developing history.

Source water is through fine filter, seed activity carbon filter, compression charcoal filter etc.; pressurize by topping-up pump again; utilizing the aperture is that 1/10000 μ m (is equivalent to 1/6000 of intestinal bacteria size; virus 1/300) RO film (reverse osmosis membrane); make the water of higher concentration become low concentration of water; the impurity that industrial pollutants, heavy metal, bacterium, virus etc. are sneaked in the water is in a large number all isolated simultaneously; thereby reach the physical and chemical index and the hygienic standard of drinking regulation; output to pure water, is the optimal selection that human body in time replenishes high-quality moisture to clear.Because the water purity that RO film Reverse Osmosis Technology is produced is the highest in the human at present cutting water technology of grasping, its cleanliness factor almost reaches 100%, so people claim that this machine for producing water device is the reverse osmosis purified water machine.

Reverse osmosis processing technological flow figure can be divided into three parts by the sequencing of handling: pre-treatment, membrane sepn and aftertreatment.The water quality of source water, the water yield etc. are adjusted in pre-treatment, satisfying the requirement that membrane sepn is handled, thereby guarantee final treatment effect.The basic parameter of the water inlet that general poly aromatic acid amides composite membrane assembly requires is: pollution index (FI)＜3～5; Free chlorine residual＜0.1mg/L; Inflow temperature: 1～45 ℃; PH value: 4～10.Some index that aftertreatment is primarily aimed at the reverse osmosis treating water can't satisfy final requirement and the treatment measures taked, generally adopts technology alone or in combination such as the degassing, uviolizing, ultrafiltration.

The reverse osmosis pure water system adopts different technology according to different source water qualities.General tap water is after the one-level reverse osmosis system is handled, produce water conductivity＜10 μ s/cm, behind the secondary reverse osmosis system, produce water conductivity＜5 μ s/cm even lower, behind reverse osmosis system, be aided with ion-exchange unit or EDI equipment can prepare ultrapure water, make resistivity reach 18 megohms.

The utility model content

In view of this, the technical problems to be solved in the utility model is to be provided as and solves the problems of the technologies described above, the technical solution of the utility model is achieved in that a kind of pair of film do not have waste water reverse osmosis purified water machine, it comprises the source water valve that connects in turn, the first step is crossed filter core, the gac filtration device, filter core is crossed in the second stage, low-voltage solenoid valve, topping-up pump, RO film chamber, water side in the described RO film chamber is divided into waste water and two water routes of pure water, the pure water water route comprises that RO film chamber feeds in the retaining pressure-pot through high-pressure valve, and the retaining pressure-pot also is connected with rearmounted exquisite activated charcoal filter and water purifying valve; The waste water water route comprises that process molecular screen membrane chamber, RO film chamber and check reverse flow valve are connected to the low pressure end of topping-up pump, and an end in molecular screen membrane chamber is connected with electromagnetism flush valve, time controller.

It is that 5um crosses filter core that the described first step is crossed filter core.

It is that 1um crosses filter core that filter core is crossed in the described second stage.

The technique effect that the utility model reaches is as follows: the utility model is a kind of tap water and underground water to be carried out the tap water terminal process equipment that secondary deep purifies; the first step, second stage filter core deep bed filter by polypropylene melt-blown are filter just; again by the gac filtration device remove chlorine residue and heavy metal etc., gac filtration device profound level has been adsorbed pre-treatment becomes percolation water; reverse osmosis is carried out in pressurization to percolation water, produces the pure water that can directly drink raw.Isolated waste water is constantly compression in the molecular screen membrane chamber, and through the filtering of RO film high precision, percolation water enters the topping-up pump low pressure end once more, thereby realizes the waste water cycling and reutilization.Then,, start to control the electromagnetism flush valve, the molecular screen membrane chamber concentrated solution that accumulates that concentration constantly raises in the inherent unit time is washed away by time controlled system.
