Description

A kind of band heating in combination formula reverse osmosis water purifier

Technical field

The present invention relates to a kind of water-purifying machine, it is specifically related to a kind of band heating in combination formula reverse osmosis water purifier.

Background technology

The subject matter that current product exists is that soak test total number of bacterial colony exceeds standard.But existing reverse osmosis water purifier does not all kill the filter core of bacterium colony, the water purifying out at whole reverse osmosis water purifier so again can produce total number of bacterial colony and exceed standard inside pressure pot, cause the injury to HUMAN HEALTH, existing reverse osmosis water purifier RO reverse osmosis membrane duration of service is short, do not have good control for the time changing RO reverse osmosis membrane, cause or can not get timely replacing, or RO reverse osmosis membrane is not also just changed to work-ing life, causes waste.

The water purifier of prior art, RO reverse osmosis membrane only has the work-ing life of 2-6 month usually, because after life-time service the surface sediment of RO reverse osmosis membrane be difficult to through particle, flow rate of water flow is caused to slow down, surface is breed bacteria easily, and make the output capacity of pure water significantly reduce, usual prior art pure water and the waste water ratio of draining are 1:4, because RO reverse osmosis membrane packed particle breed bacteria then can make this ratio significantly improve.And use technical scheme of the present invention, owing to arranging return line at waste water outlet end, effluent part is back to feed-water end, the flow velocity flowing through RO reverse osmosis membrane is impelled to accelerate, certain washing action is served to RO reverse osmosis membrane, avoid surperficial macrobead to pile up and cause perviousness to be deteriorated and breed bacteria, usually can make more than the life to 18 month of RO reverse osmosis membrane.Simultaneously because effluent part backflow is again through RO reverse osmosis membrane, improve the output capacity of pure water, through the control of variable valve, pure water and the waste water ratio of draining can be reached between 1:2 to 1:1 usually.In addition, owing to have employed return of waste water and variable valve, water pressure invariableness when product runs can be realized, avoid the situation causing damage of product because hydraulic pressure is excessive to occur.In addition, water butt adopts " gac+KDF+ or medical stone " filtrate, and (Kai get Fei KDF is highly purified copper/zinc alloy granules, it carries out water treatment work by micro-electrochemical redox reaction Redox, when contacting with water, two kinds of metals in alloy form countless little galvanic cell system on submicroscopic yardstick, the speed of response that this material has powerful response capacity and is exceedingly fast in water, can remove in water up to metal ion and compounds such as the lead dissolved in the chlorine of 99 % and water, mercury, nickel, chromium.To anti-bacteria, fungi, dirt, algae to grow effect distinguished.Can guarantee to be stored in water in water butt because of the long period need not and not breed bacteria, prevent the pure water after purification because leaving the secondary pollution formed in water butt in.Prior art utilizes the time to calculate for the work-ing life of RO reverse osmosis membrane usually, and ignores RO reverse osmosis membrane self work because water quality, flow are on the impact in its work-ing life, usually changes RO reverse osmosis membrane by the cycle of 2-6 month.RO reverse osmosis membrane is the higher and equipment played a major role as relative price in water-purifying machine, and such way has two problems usually, and one is that RO reverse osmosis membrane does not damage itself, and temporally changes the use cost adding user undoubtedly; Another one problem is that RO reverse osmosis membrane has damaged but also not to the replacement cycle, and now uses the water quality of purification beyond doubt to go wrong and energy consumption strengthens.The present invention by being also provided with the way of pressure-display device after the magnetic valve at RO reverse osmosis membrane processing unit water inlet pipe place and water inlet pipe, whether normal by monitoring this place's hydraulic pressure, monitor that whether RO reverse osmosis membrane is working properly, judge whether to need to change RO reverse osmosis membrane with this.Because RO reverse osmosis membrane is as normal work, hydraulic pressure is stablized usually, as RO reverse osmosis membrane cisco unity malfunction, the water-permeable of RO reverse osmosis membrane can be caused to be deteriorated due to the intransitable particle of surface sediment, cause variation in water pressure, monitor that the working order of RO reverse osmosis membrane determines the need of replacing with this, can more in time, grasp the replacing construction of RO reverse osmosis membrane accurately.Selecting more to provide to user, heating tank can be installed additional in the water outlet pipe part of pure water, heat for the pure water that water outlet pipe end is flowed out.
