Description
Technical field
The utility model relates to a kind of cleaning device more particularly to a kind of off-line cleaning device for reverse osmosis membrane.
Background technique
Reverse osmosis cleaning is typically cleaned online at present, and during (1) on-line cleaning, equipment stops producing water transport
Row is in clean cycle state, until cleaning terminates, can just be transferred to normal operation；(2) during on-line cleaning, whole branch
Several membrane component series connection cleanings in membrane tube, pollutant, which has to pass through every membrane component, can just leave system, make cleaning cannot be thorough
(3) during on-line cleaning, scheme working-out and cleaning operation can only be carried out according to whole system operation conditions, cleaning each time is only
Membrane components all in system can be cleaned with a kind of medicament, and scavenging period, cleaning temperature, cleaning condition are the same；(4) exist
Line cleaning, can only partially restore the operating status of whole system；(5) during on-line cleaning, cleaning solution is full of whole system, makes
The pollutant stripped down from seriously polluted membrane component is recirculated to system, causes to cleaner membrane component secondary
The hidden danger of pollution.
Utility model content
Stifled serious to solve long-term reverse osmosis membrane dirt, the cycle of operation is short, and frequently, frequent clean film service life is significantly for cleaning
The technical issues of reduction, the utility model provide a kind of off-line cleaning device for reverse osmosis membrane.Heavier film preferably can be blocked up to dirt
Cleaning is completed, without influencing or damaging the operation of other films.
The technical solution adopted in the utility model:
Off-line cleaning device for reverse osmosis membrane, it includes cleaning water tank, cleaning pump, cleaning filter, and the cleaning water tank is logical
Over cleaning pump is connect with cleaning filter, the piping connection of the cleaning filter and more Membrane cleaning devices, Membrane cleaning device
On be configured with water-in and water-out pipeline, the outlet of the Membrane cleaning device also passes through pipeline and returns to cleaning water tank, the Membrane cleaning device
Pipeline on pressure gauge is installed.
Further, the Membrane cleaning device includes the reverse osmosis membrane of shell and installation inside the shell.
Further, the Membrane cleaning device is 10, and two rows respectively install 5 in parallel.
Compared with prior art, the utility model has the beneficial effects that film is cleaned offline because to single branch Membrane cleaning, cleaning solution is logical
Amount is big, and cleaning effect substantially improves, and not will cause secondary pollution, and the offline cleaning effect of film is more preferable, blocks up serious film to part dirt
It is cleaned offline, the spare film of system conversion during cleaning, guarantees that system operates normally.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
1, cleaning water tank, 2, cleaning pump, 3, cleaning filter, 4, Membrane cleaning device, 41, shell, 42, reverse osmosis membrane, 5,
Water inlet line, 6, outlet conduit, 7, pressure gauge.
Specific embodiment
In order to deepen the understanding to the utility model, with reference to the accompanying drawing and specific embodiment is described in detail, this
Embodiment described in specification is only used for explaining the utility model, is not used to limit the utility model.
Shown in Fig. 1, the off-line cleaning device for reverse osmosis membrane of the utility model, it includes cleaning water tank 1, cleaning pump 2 and clear
Filter 3 is washed, cleaning water tank 1 is connect by cleaning pump 2 with cleaning filter 3, cleaning filter 3 and more Membrane cleaning devices 4
Piping connection, be configured with water inlet line 5 and outlet conduit 6 on Membrane cleaning device 4, the outlet of Membrane cleaning device 4 also passes through pipe
Road returns to cleaning water tank 1, is cleaned again, pressure gauge 7 is equipped on the pipeline of Membrane cleaning device 4.
Membrane cleaning device 4 includes shell 41 and the reverse osmosis membrane 42 being mounted in shell 41.
The cleaning system of the utility model increases by 10 Membrane cleaning devices, and two rows respectively install 5 in parallel.Cleaning system
(two groups are designed using upper and lower water-in and water-out) is arranged in parallel using upper and lower two groups.Serious film is blocked up to part dirt to be cleaned offline,
The spare film of system conversion during cleaning guarantees that system operates normally.
Membrane off-line cleaning system dock with former cleaning system, is used original system and is cleaned water tank, cleaning pump, cleaning filter with
And part cleaning pipeline, serious film is blocked up into dirt and is extracted from system, is fitted into off-line cleaning device, according to it is dirty block up object into
Row configures corresponding cleaning solution and carries out chemical cleaning.
The utility model has the advantage that
(1) film is cleaned offline because to single branch Membrane cleaning, cleaning solution flux is big, and cleaning effect substantially improves, while to single branch
Film carries out offline cleaning and not will cause the lower foul of cleaning causing secondary pollution to rear road film, it is logical film clean offline with online clearly
It washes and compares, the offline cleaning effect of film is more preferable.
(2) film is cleaned offline because cleaning effect is good, and operation pressure decline is obvious after cleaning replacement, average one after putting equipment in service
Section operation pressure can decline 0.16MPa, and water flow is produced after putting equipment in service and improves 10 tons, running current declines about 6A, can save in year
About 20,000 degree of electricity, this is the effect that on-line cleaning is not achieved.
