Description
Technical field
The utility model relates to a kind of security personnel's filtration unit for reverse osmosis system.
Background technology
Reverse osmosis system is desalting plant important in water treatment, is also current seawater and brackish water desalination, one of most economical means prepared by pure water and ultrapure water.It makes solvent in solution by reverse osmosis system via reverse osmosis membrane separation out at a pressure sufficient.
Usually the multilayer material adopting several groups to fold successively in a membrane element due to reverse osmosis membrane is wound on a pipe core together, require strictly to the influent quality entering reverse osmosis membrane like this, pollution index requires≤5, so need to arrange cartridge filter before reverse osmosis unit, its objective is and prevent particle large in solution from entering reverse osmosis membrane, scratch film surface, affect filter effect.
Because reverse osmosis requires that the temperature of solution is at 15 ~ 25 DEG C, this temperature is applicable to the growth of bacterium, therefore when water is by cartridge filter, bacterium and decomposed substance thereof can be adsorbed on cartridge surface, water flux is caused to decline, current treatment process is frequent more renew cartridge, and cause filter core rate of utilization low, running cost is high.
Summary of the invention
Technical problem to be solved in the utility model is the present situation for prior art, provides a kind of security personnel's filtration unit for reverse osmosis system that automatically can carry out back flushing and sterilization.
The utility model solves the problems of the technologies described above adopted technical scheme: this is used for security personnel's filtration unit of reverse osmosis system, comprise cartridge filter, the top of described cartridge filter is provided with ventpipe, described ventpipe is provided with breather valve, the bottom of cartridge filter is provided with blow-off pipe, and described blow-off pipe is provided with wash water valve; It is characterized in that also being connected with pump around circuit pipe between described ventpipe and described blow-off pipe, described pump around circuit pipe is provided with water sprayer and dosing pump, and the entrance of described water sprayer connects microbicide solution source.
Conveniently control, can also be connected with bypass duct for emptying at described pump around circuit pipe, described bypass duct is provided with bypass control valve.
Be provided with diaphragm valve between described pump around circuit pipe and described ventpipe, between described water sprayer and described blow-off pipe, be provided with the first control valve, between described water sprayer and described dosing pump, be provided with the second control valve.
Compared with prior art, cartridge filter bottom outlet pipeline and top vent pipeline are communicated with by the utility model, form pump around circuit, return wire increases portable pipe dosing pump and water sprayer, by dosing pump circulation sterilant is drawn in cartridge filter and circulates, regular sterilization, avoid and change cartridge filter inner filter core, extend the work-ing life of filter core, reduce running cost, and use more convenient.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figure 1, this security personnel's filtration unit being used for reverse osmosis system comprises:
Cartridge filter 1, its top exit is connected with ventpipe 2, and ventpipe 2 is provided with breather valve 14, and its outlet at bottom is connected with blow-off pipe 3, and blow-off pipe 3 is provided with wash water valve 15, and blow-off pipe 3 is connected to blowdown trench 9.
Pump around circuit pipe 7, is connected between ventpipe 2 and blow-off pipe 3, which is provided with water sprayer 4 and dosing pump 5, and the entrance of water sprayer 4 connects microbicide solution source, and the present embodiment connects microbicide solution bucket 6.Be provided with diaphragm valve 8 between pump around circuit pipe 7 and ventpipe 2, between water sprayer 4 and blow-off pipe 3, be provided with the first control valve 12, between water sprayer 4 and dosing pump 5, be provided with the second control valve 13.
Pump around circuit pipe 7 is also connected with the bypass duct 10 for emptying, and bypass duct 10 is provided with bypass control valve 11.
After cartridge filter runs for some time, when needing to carry out sterilization cleaning to cartridge filter, open diaphragm valve, the first control valve and the second control valve, pneumatic water sprayer and dosing pump, microbicide solution in microbicide solution bucket is drawn out of under the effect of dosing pump and water sprayer, cartridge filter is entered from the bottom of cartridge filter is reverse via pump around circuit pipe, after the process of cartridge filter internal recycling, kill in cartridge filter the bacterium growing and accumulate, then discharge from the ventpipe of cartridge filter and enter pump around circuit pipe, drain from bypass duct.After rinsing with water again, can handle well cartridge filter.Avoid the trouble changing filter core of security filter, also extend the work-ing life of filter core of security filter simultaneously, reduce running cost.
