Abstract
The utility model discloses a kind of pressure vessel for reverse osmosis, it includes a membrane pressure vessel, one end is equipped with water inlet interface, the other end, which is equipped with, produces water interface, both ends are equipped with concentrated water outlet and are provided with switch control valve, and water inlet end branches out the other end that a conduit is connected to container, and water inlet is also provided with switch control valve, it is equipped with reverse-osmosis membrane element in container, sealing ring is equipped between reverse-osmosis membrane element and membrane pressure vessel.The utility model is controlled by pipeline connection with valve, under the premise of free of demolition, realizes the positive and negative two-way use to reverse-osmosis membrane element, reduce the probability that membrane component is contaminated object blocking in use, the cleaning frequency is reduced, is prolonged the service life, water treatment efficiency is more preferably.
Description
Technical field
The utility model relates to a kind of pressure vessel for reverse osmosis.
Background technique
Reverse osmosis technology is to realize solute and solvent by the selective retention effect of reverse osmosis membrane using osmotic pressure principle
The impurity such as inorganic ions, bacterium, virus, organic matter in raw water can be removed, are widely applied by the high-end water treatment technology of separation
It is multiple in sea water desalination, bitter desalination, drink water purifying, industrial extra-pure water production and medicine, electronics, chemical industry and food etc.
Field.
Reverse osmosis membrane is inevitably affected by contaminants interfering during carrying out water process, water process is caused to be imitated
The reduction of rate, big multi-pollutant can accumulate runner, block the proper flow of water, and the water flux decline of film reduces working efficiency.
Utility model content
The purpose of the utility model is to provide a kind of novel pressure vessel for reverse osmosis, under the premise of without disassembly, it can be achieved that
The two-way use of reverse osmosis membrane, to prevent pending water from entering showing for the accumulation of pollutant caused by membrane component from one end always
As.Pending water enters reverse-osmosis membrane element from a direction and the pollutant accumulated, there is a strong possibility can by from other direction into
The pending water entered rinses out, and the positive and negative two-way possibility for being contaminated object blocking using membrane component is greatly reduced increases membrane element
The service life of part reduces the cleaning frequency, and water treatment efficiency is more preferably.
The purpose of this utility model is achieved through the following technical solutions:
A kind of pressure vessel for reverse osmosis, it includes a membrane pressure vessel, and one end is equipped with water inlet interface, and the other end is equipped with production water and connects
Mouthful, both ends are equipped with concentrated water outlet and are provided with switch control valve, and water inlet end branches out a conduit and is connected to the another of container
One end, water inlet are also provided with switch control valve, are equipped with reverse-osmosis membrane element, reverse-osmosis membrane element and film pressure in container
Sealing ring is equipped between container.
The beneficial effects of the utility model are: the utility model provides a kind of pressure vessel for reverse osmosis, pass through pipeline connection and valve
Door control realizes the positive and negative two-way use to reverse-osmosis membrane element under the premise of free of demolition, reduces membrane component in use process
In be contaminated object blocking probability, reduce the cleaning frequency, prolong the service life, water treatment efficiency is more preferably.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure, 1- water inlet interface, 2- control valve, 3- sealing ring, 4- reverse osmosis membrane, 5- conduit, 6- control valve, 7- production
Water interface, the outlet of 8- concentrated water, 9- control valve, 10- central tube, 11- membrane pressure vessel, the outlet of 12- concentrated water, 13- control valve.
Specific embodiment
The utility model is further described with reference to the accompanying drawing, but the protection scope of the utility model is not limited to
It is as described below.
As shown in Figure 1, a kind of pressure vessel for reverse osmosis, it includes a membrane pressure vessel 11, and one end is equipped with water inlet interface 1, separately
One end be equipped with produce water interface 7, both ends be respectively equipped with concentrated water outlet 8 with concentrated water outlet 12, and be respectively provided with switch control valve 9 with
Control valve 13, water inlet end branch out the other end that a conduit 5 is connected to container, and water inlet is also respectively provided with switch control
Valve 2 and control valve 6, container is interior to be equipped with reverse-osmosis membrane element 4, is equipped with central tube 10, reverse-osmosis membrane element and film in element
Sealing ring 3 is equipped between pressure vessel.
In use process, when open state is presented in control valve 2 and control valve 9；Control valve 6 is in control valve 13
When existing closed state, water enters container from valve 2, and by filtering, concentrated water is discharged from valve 9, produces water and exports from is produced from the mouth of a river 7, water
Right side is flowed to from the left side of reverse osmosis membrane.When closed state is presented in control valve 2 and control valve 9；Control valve 6 and control valve
When 13 presentation open state of door, water enters container from valve 6, and by filtering, concentrated water is discharged from valve 13, produces water from the production mouth of a river 7
Export, water flow to left side from the right side of reverse osmosis membrane.By positive and negative two-way use, pollutant blocking reverse osmosis membrane is substantially reduced
Probability.
