Abstract
The utility model discloses a water treatment system for utilizing pure water to flush a reverse osmosis membrane and particularly relates to the water treatment system for utilizing the pure water to flush a reverse osmosis membrane element. The water treatment system comprises a source water tank, the source water tank is connected with an inlet of a reverse osmosis device composed of a plurality of reverse osmosis membrane pipe fittings which are arranged in parallel, a pure water outlet of the reverse osmosis device is connected with a pure water tank of a pure water collecting device, a flushing pump is further arranged between the pure water tank and an inlet of the reverse osmosis device, a water inlet of the flushing pump is connected with the pure water tank, and a water outlet of the flushing pump is connected with the inlet of the reverse osmosis device. The pure water is utilized to flush the reverse osmosis membrane element, so that the surface of the membrane element is flushed to be extremely clean, scaling of inorganic salt is avoided to the largest extent, times of chemical cleaning of the reverse osmosis membrane and dosage of chemicals are also reduced simultaneously, pollution to the environment is reduced, the service life of the membrane element is greatly prolonged, the replaced membrane elements are reduced, and the water treatment system has extremely high economic benefit.
Description
Technical field
The utility model relates to the technical field of water treatment facilities, especially a kind of water treatment system of utilizing pure water to wash reverse-osmosis membrane element.
Background technology
At known water-treatment technology field; Former water is divided into two-way after getting into counter-infiltration system; One Reuter crosses the reverse osmosis membrane surface and becomes product water; Another curb reverse osmosis membrane surface is parallel to be moved and concentrates gradually, in these water that concentrate, has comprised a large amount of salinities, even has also had organic matter, colloid, microorganism and bacterium, virus etc.When counter-infiltration system normally moves; With certain flow rate, these pollutants are difficult to deposit concentrated stream along the reverse osmosis membrane surface, if but counter-infiltration system is out of service; These pollutants will be deposited on the surface of film immediately; Membrane component is polluted and fouling, so self-stripping system will be set in counter-infiltration system the membrane component surface is washed, to prevent the deposition of these pollutants.
In the prior art, be to utilize the former water in the water tank of source that the membrane component surface is washed, because former glassware for drinking water has a lot of impurity and salinity; Developing result is very limited; Can not effectively prevent the incrustation of calcium salt and magnesium salts, follow-up needs use the method for Chemical cleaning that membrane component is washed in a large number, owing in Chemical cleaning, will use the medicine bronsted lowry acids and bases bronsted lowry; Not only can reduce the service life of membrane component greatly, also cause environmental pollution easily.
The utility model content
The technical problem that the utility model will solve is: provide a kind of developing result good, can reduce the Chemical cleaning number of times and improve the membrane component water treatment system in service life.
The utility model solves the technical scheme that its technical problem adopted: a kind of water treatment system of utilizing the pure water rinsing reverse osmosis membrane; Comprise the source water tank; Described source water tank is connected with the inlet of the reverse osmosis unit that a plurality of reverse osmosis membrane pipe fittings that are provided with by parallel connection are formed; The pure water outlet of described reverse osmosis unit links to each other with pure water collection device pure water case; Also be provided with flushing pump between the inlet of described pure water case and reverse osmosis unit, the water inlet of described flushing pump links to each other with the pure water case, and the delivery port of described flushing pump links to each other with the inlet of reverse osmosis unit.
The beneficial effect of the utility model the utility model is: the utility model utilizes pure water to wash reverse-osmosis membrane element; Because the pure water in the pure water case is treated very clean water; Salt seldom; So come the flushing membrane element surface with it, it is very clean that the membrane component surface washing is got, and prevented the fouling of calcium salt and magnesium salts to the full extent.Simultaneously, owing to adopted the pure water rinsing technology, the Chemical cleaning number of times of reverse osmosis membrane is significantly reduced, Chemical cleaning medicine bronsted lowry acids and bases bronsted lowry consumption significantly reduces; Both practiced thrift cost, reduced pollution again, improved the life-span of membrane component greatly environment, change membrane component time lengthening 50%-80%; The membrane component of changing under the identical like this production capacity is just few, because membrane component is external import, price is more expensive; For example, suppose per hour to produce 50 tons pure water equipment, use more than 100 of the reverse osmosis membrane of model 8040; The market price of every membrane component is about 4500 yuan, and the total fund of saving can reach 450,000, so the utlity model has high economic benefit.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
Among the figure: 1. source water tank, 2. reverse osmosis membrane pipe fitting, 3. reverse osmosis unit, 4. pure water case, 5. flushing pump.
The specific embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of water treatment system of utilizing the pure water rinsing reverse osmosis membrane of the utility model as shown in Figure 1; Has source water tank 1; Source water tank 1 is connected with the inlet of the reverse osmosis unit 3 that a plurality of reverse osmosis membrane pipe fittings 2 that are provided with by parallel connection are formed, and the pure water outlet of reverse osmosis unit 3 links to each other with pure water collection device pure water case 4, and reverse osmosis unit 3 also is provided with other dense water out; Also be provided with flushing pump 5 between the inlet of pure water case 4 and reverse osmosis unit 3; The water inlet of flushing pump 5 links to each other with pure water case 4, and the delivery port of flushing pump 5 links to each other with the inlet of reverse osmosis unit 3, when equipment is stopped transport; Utilize the transportation of pure water through flushing pump 5 in the pure water case 4, the reverse osmosis membrane in the reverse osmosis unit 3 is washed.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
