Abstract
The utility model discloses a reverse osmosis membrane on-line self-cleaning system which is characterized by comprising a cleaning pipeline connected with a water inlet pipeline of a reverse osmosis system. The cleaning pipeline is provided with a cartridge filter, a cleaning pump and a cleaning cylinder in sequence. A water production pipeline of the reverse osmosis system is provided with a cleaning backflow pipeline connected with a cleaning cylinder. Adopting the on-line cleaning technology, the reverse osmosis membrane on-line self-cleaning system is capable of saving workload, solving the problem of membrane fouling fast and promptly, and getting rid of disadvantages of off-line membrane cleaning. The reverse osmosis membrane on-line self-cleaning system has the advantages that the membrane is cleaned fast and promptly by automatic control so that both time and labour are saved; the membrane is free from being repeatedly disassembled membrane by the method of on-line cleaning so that manpower and material resources are saved, simple and convenient operation and low cleaning cost are achieved. The requirement of membrane core disassembling and the operation of high strength are avoided. Cleaning time and temperature is controlled properly and parameters are easy to control.
Description
Technical field
The utility model relates to water treatment field, particularly a kind of reverse osmosis membrane on-line auto-cleaning system.
Background technology
Film is as a kind of macromolecule chemical material, and existing separation, concentrated, purification and desalination function have again the features such as efficient, energy-saving and environmental protection, molecular level filtration, are widely used in the industries such as reusing sewage processing, desalinization, brackish water desalination, ultra-pure water.Membrane technology is acknowledged as one of most important new technology of 21 century.Membrane separation technique mainly comprises micro-filtration, ultrafiltration, nanofiltration and counter-infiltration.
Counter-infiltration is a kind of under pressure-driven, and by means of the separation method that the selective retention effect of reverse osmosis membrane separates the solute in the solution and solvent, it is one of present topmost water technology.In the counter-infiltration system running, reverse osmosis membrane surface can since in the existence of the polluters such as mud pool, jelly, organic matter, microorganism in the former water and the film separation process to the deposition that produces that concentrates of indissoluble material, and then formation is to the pollution of reverse osmosis membrane.Therefore, need in the process of equipment operation, periodically clean reverse osmosis membrane.Conventional reverse osmosis membrane cleans and usually adopts cleaning method off-line, manual, and not only time and effort consuming, and cleaning charge is with high.Need to pull down membrane component from equipment when off-line cleans, and need the artificial film internal contamination thing of cleaning.Loaded down with trivial details hard, scavenging period length of the film of off-line dismounting, complicated operation, expense is high, waste time and energy practical application inconvenience and the risk that exists membrane component to scrap.
Summary of the invention
For the problems referred to above, the purpose of this utility model be to provide a kind of can be automatically, timely and effectively film is cleaned, save time, online, automatic reverse osmosis membrane on-line auto-cleaning system simple to operation.
For achieving the above object, the technical scheme that the utility model proposes is: a kind of reverse osmosis membrane on-line auto-cleaning system, it is characterized in that: comprise the pipe blow-through that links to each other with the counter-infiltration system inlet channel, be provided with successively cartridge filter, scavenging pump, purge tank on the described pipe blow-through, described counter-infiltration system water producing pipe road is provided with a cleaning reflux line and links to each other with purge tank.
Further, described pipe blow-through is provided with a check-valves.
Further, described pipe blow-through is provided with a flowmeter.
Further, described check-valves is pneumatic check-valves.
Adopt technique scheme, counter-infiltration on-line auto-cleaning described in the utility model system adopts online film cleaning technique, saves hand labor, can fast, in time solve membrane pollution problem, overcomes the shortcoming that the off-line film cleans, and is concrete, has following advantage:
1) adopt automation control, can be fast, in time film is cleaned, time saving and energy saving;
2) method of employing on-line cleaning without the repeated disassembled and assembled film, uses manpower and material resources sparingly, and simple to operation, cleaning charge is low;
3) need not to dismantle the film core, also need not high-intensity operation, suitably control scavenging period and temperature, parameter is simple and easy to control.
Description of drawings
Fig. 1 is the counter-infiltration system schematic diagram that reverse osmosis membrane on-line auto-cleaning described in the utility model system is installed;
Wherein: 1. purge tank, 2. scavenging pump, 3. cartridge filter, 4. flowmeter, 5. check-valves, 6. counter-infiltration system, 61. reverse osmosis membranes, 62. inlet channels, 63. water producing pipe roads, 64. dense waterpipes, 7. pipe blow-through, 8. clean reflux line.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, counter-infiltration system 6 comprises reverse osmosis membrane 61, inlet channel 62, water producing pipe road 63, dense waterpipe 64, described reverse osmosis membrane on-line auto-cleaning system comprises the pipe blow-through 7 that links to each other with counter-infiltration system 6 inlet channels 62, be provided with successively cartridge filter 3, scavenging pump 2, purge tank 1 on the pipe blow-through 7, counter-infiltration system 6 water producing pipe roads 63 are provided with a cleaning reflux line 8 and link to each other with purge tank 1, pipe blow-through 7 is provided with a check-valves 5 and flowmeter 4, check-valves 5 preferred pneumatic check-valves.
Concrete, reverse osmosis membrane on-line auto-cleaning described in the utility model system is divided into online washing and chemical cleaning online:
1) online washing: utilize the general water conservancy project skill of producing, adopt RO to produce water, carry out washing away of large flow, high flow rate, with the pollutant flushing on film surface;
2) chemical cleaning online: cleaning agent is pumped in the RO film pipe, soak a period of time, after the pollutant dissolving, coming off, produce water with RO again and clean, can be more up hill and dale with contaminant removal.
Adopt technique scheme, can save hand labor, can fast, in time solve membrane pollution problem, overcome the shortcoming that the off-line film cleans.Reverse osmosis membrane on-line auto-cleaning described in the utility model system, the valve in pipeline changes electrically operated valve into by manually-operated gate, need not to control manually, has overcome the shortcoming of Manual-cleaning time and effort consuming.In addition, by being set, instrument can realize Real Time Monitoring to temperature, flow, pressure.Concrete, when following contamination characteristics (aquifer yield decline 10-15% occurring, produce water deteriorating water quality 10-15%, perhaps the pressure drop between feedwater and dense water increases 10-15%, producing the water desalination rate changes when being no more than 5%, showing that film has pollutes or dirt occurs, thereby in time, rapidly reverse osmosis membrane is cleaned.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; within not breaking away from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
