Abstract
The utility model provides a reverse osmosis security filter which comprises a housing and a plurality of filter elements, wherein the filter elements are symmetrically and longitudinally distributed in the housing by taking a center of the cross section of the housing as a center; a water inlet, a cleaning liquid inlet and an air inlet are formed at a water inlet end of the housing; a water outlet, a cleaning liquid outlet and an air outlet are formed at a water production end of the housing; and valves are arranged at the water inlet, the cleaning liquid inlet, the air inlet, the water outlet, the cleaning liquid outlet and the air outlet. According to the reverse osmosis security filter, the mode of cleaning fluid and compressed air back flushing is adopted, so that a compact layer and sundries can be removed sufficiently and effectively; the filter elements can sufficiently recover functions; the water permeability is improved; and the service lives of the filter elements of the security filter can be effectively prolonged by 2-3 times.
Description
Technical field
The utility model relates to a kind of embrane method sewage-treatment plant, relates in particular to a kind of reverse osmosis cartridge filter.
Background technology
Counter-infiltration system is the visual plant of global range water quality desalination, is widely used in water-treatment technology field.Former water is before entering reverse osmosis unit, and the process cartridge filter filters the technique that is absolutely necessary.But, increasingly sophisticated along with current raw water quality, the increasing of large reverse osmosis system, the filter element replacing cost of cartridge filter has just appeared suddenly out.Especially at present adopt many large flux filter cores, single Zhi Chengben is high, and the annual expense of changing is just particularly considerable.
Filter core of security filter mostly adopts and melts and sprays or folding filter core, and filter type is grossflow filtration, also claims dead-end filtration, pollutant is trapped in the surface of filter core, and along with increasing of cartridge surface pollutant, the water flowing of filter core will descend, drop to certain degree, just need more renew cartridge.Generally to judge according to the operating pressure before and after filter core is poor.Surpass certain value and just be considered as the end of run, need more renew cartridge (adopting at present 0.07MPa is the in the majority of terminal).
It is basis that the pollutant of cartridge surface be take particle, organic matter; Owing to not suppressing the composition of microorganism in the running environment of cartridge filter, therefore can grow very soon a large amount of microorganisms on the organic matter in enrichment on cartridge surface, and the coherent substance of growth of microorganism, dead generation can form the compacted zone of the non-constant of water penetration, this is the main cause that causes the filter core water-flowing amount to descend.And prior art can only solve this problem by renew cartridge more.
The utility model content
Technical problem to be solved in the utility model is to overcome above-mentioned deficiency, provides a kind of and can realize that the oneself cleans, the reverse osmosis cartridge filter of long service life.
The reverse osmosis cartridge filter that the utility model provides, comprise housing and a plurality of filter core, and described a plurality of filter cores, centered by the cross-section center of housing, are symmetry and vertically are arranged in housing; The water inlet end of described housing is provided with water inlet, cleaning fluid import, air inlet, produces water end (W.E.) and is provided with delivery port, rinse liquid outlet, gas outlet; Described water inlet, cleaning fluid import, air inlet, delivery port, rinse liquid outlet, place, gas outlet are equipped with valve.
Preferably, the water inlet end of described housing and water side are equipped with pressure sensor.
Preferably, the water inlet end of described housing is provided with water-locator, and described water-locator is connected with water inlet.
Preferably, described filter core is the ultra high molecular polyethylene filter core.
Preferably, the filtrate gap of described filter core is 0.5-5 μ m.
The reverse osmosis cartridge filter that the utility model provides, due to the mode that has adopted cleaning fluid+compressed air blowback, can fully effectively remove compacted zone and foreign material, thereby make the abundant restore funcitons of filter core, raising water penetration, can effectively extend filter core of security filter life-span 2-3 doubly.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
With reference to the accompanying drawings, in conjunction with specific embodiments the utility model is further described, to understand better the utility model.
As shown in Figure 1, the present embodiment provides a kind of reverse osmosis cartridge filter, and main body is housing 1, and the inside of housing 1 is provided with a plurality of filter cores 2, and filter core 2, centered by the cross-section center of housing 1, is the symmetry (not shown) of vertically arranging.In the upper end of housing inner housing 1, be water inlet end, lower end is water side.Water inlet end is provided with water inlet 3, cleaning fluid import 4, air inlet 5, produce water end (W.E.) and be provided with delivery port 6, rinse liquid outlet 7, gas outlet 8, water inlet 3, cleaning fluid import 4, air inlet 5, delivery port 6, rinse liquid outlet 7,8 places, gas outlet are equipped with the valve (not shown).
The water inlet end of housing 1 and water side are equipped with pressure sensor 9.
The water inlet end of housing 1 is provided with water-locator 10, and described water-locator 10 is connected with water inlet 3.
During use, close the valve of cleaning fluid import 4, air inlet 5, rinse liquid outlet 7, gas outlet 8, open the valve of water inlet 3, delivery port 6, normally carry out water filtration.During the compressed air blowback, open the valve of compressing into gas port 5, gas outlet 8, close the valve of water inlet 3, cleaning fluid import 4, rinse liquid outlet 7, delivery port 6, compressed-air actuated pressure can be 3Bar.Discharged after the compressed air blowback, in the time of discharge, opened the valve of cleaning fluid import 4, rinse liquid outlet 7, closed the valve of air inlet 5, gas outlet 8, water inlet 3, delivery port 6, with cleaning fluid, rinse and discharge.
Above specific embodiment of the utility model be have been described in detail, but it is as example, the utility model is not restricted to specific embodiment described above.To those skilled in the art, any equivalent modifications that this practicality is carried out and alternative also all among category of the present utility model.Therefore, not breaking away from the equalization conversion of doing under spirit and scope of the present utility model and revising, all should be encompassed in scope of the present utility model.
