The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be those skilled in the art will recognize that, protection domain of the present utility model is made to more explicit defining.
Fig. 1 has shown the structure principle chart of the UF ultrafiltration membrane filter in the utility model with backwashing function.As shown in Figure 1, this UF ultrafiltration membrane filter comprises the filter element 1 of at least two.In the present embodiment, this UF ultrafiltration membrane filter comprises four filter elements 1.Each filter element 1 comprises the filtration module of at least two, and each filtration module comprises cartridge filter 2, is arranged on the UF ultrafiltration membrane filter element 3 in cartridge filter 2.UF milipore filter becomes concentrating and separating new and high technology, in water treatment field, is most widely used.It is to use pressure differential to promote film separation process, and the solution in raw material sees through membrane component by high pressure, has now just reached the object of concentrating and separating and solution purification.The whole handling process of this equipment can not cause any pollution, so be subject to the favor of all trades and professions.
The top of each cartridge filter 2 is provided with water inlet 4 and delivery port 5, the bottom of each cartridge filter 2 is provided with sewage draining exit 6, the water inlet 4 of the cartridge filter 2 in same filtration module is connected to form and one enters aquaporin 9, the delivery port 5 of the cartridge filter 2 in same filtration mould is connected and forms aquaporin 10, the sewage draining exit 6 of the cartridge filter 2 in same filtration module is connected and forms drain outlet 11, the aquaporin 9 that enters of each filtration module is provided with a water intaking valve 7, each exhalant canal 10 that filters module is connected, the drain outlet 11 of each cartridge filter 2 is provided with a blowoff valve 8.Filtration module in each filter element 1 is in same duty.Concrete, each filter element 1 comprises that two are filtered module.
Filter element 1 has and filters and two duties of backwash, and when a certain filter element 1 is during in filtration condition, the water intaking valve 7 of this filter element 1 is opened and blowoff valve 8 cuts out.Need the water filtering to flow in water intaking valve 7 from former water inlet 13, then enter filter element 1 from the water inlet 4 of filter element 1, by completing filtration after UF ultrafiltration membrane filter element 3.Complete clean water outlet 14 these UF ultrafiltration membrane filters of discharge from the delivery port 5 of filter element 1 flows to filter again after filtration.
When a certain filter element 1 is during in backwash state, the water intaking valve 7 corresponding with this filter element 1 closed, and the blowoff valve 8 corresponding with this filter element 1 opened.At least one in remaining filter element 1 is in filtration condition.From the clean water flowing out in filtration condition, flow to the delivery port 5 of the filter element 1 in backwash state, filter element 1 in backwash state is carried out to backwash, and by drain outlet 11, flow to blowdown outlet 12 from the sewage draining exit 6 of filter element 1, finally flow out UF ultrafiltration membrane filter.
In the present embodiment, the precision of UF ultrafiltration membrane filter is 0.01 μ m to 0.1 μ m, and the flow of UF ultrafiltration membrane filter is 1t/h to 100t/h.Water intaking valve 7 and described blowoff valve 8 are respectively two pass ball valves.Water intaking valve 7 and described blowoff valve 8 are a tee ball valve.
UF ultrafiltration membrane filter is applicable to the filtration of low viscosity liquid, had both can be used for bodies for purifying fluids as liquid, modularization self-cleaning filters such as seawater, oils, sewage, solvent, gasoline, coking chemical waste water, diesel oil, cooling fluids, meet the cleanliness factor requirement of lower road technique, also can be used for protecting downstream key equipment, avoid causing U.S. button apparatus service life to shorten or operational efficiency reduction because of Particle Blocking, wearing and tearing or fouling; Also can utilize this filter to collect backwash and discharge liquid, recovery high value solid particle wherein etc.UF is super to consider filter, adopt its effectively catching aperture of polypropylene hollow fiber membrane (inner pressed) is 0.1-0.01um, and all kinds of micels of flowing through microorganism in seawater and be greater than this aperture are held back.When liquid is during by filter core. granule foreign is wherein intercepted on the surface of filtering layer.Accumulation forms filter cake.Pressure reduction between filter element 1 import and export is become greatly gradually, when pressure reduction reaches certain preset value, show that filter cake reaches certain thickness, now the filtered stream of filtering layer is put more and more less, differential pressure controller starts backwash action, and liquid is moving to outbound flowing from filtering layer inner counter, takes away surperficial impurity
In another preferred embodiment, the delivery port 5 of each filter element 1 is also circumscribed with a cleaning apparatus, and when the water intaking valve 7 of filter element 1 is closed, described cleaning apparatus passes into clean gas flow to the delivery port 5 of described filter element 1.Clean fluid can be mixed for liquid pressing contracting air.The filter cake that utilizes the clean fluid of outside access to assist filter cartridge flushing surface, during backwash, controller cuts off the terminal valve of one of them filter element 1, then open the inlet valve of auxiliary recoil fluid, lead to a certain amount of fluid, when the inlet pressure of kickback pressure arrival recoil fluid, open rapidly blowoff valve 8, there is liquid: (gas) presses pulse, remove rapidly the filter cake of cartridge surface, then close recoil fluid inlet valve, close blowoff valve 8, open material inlet wealthy, open outlet valve, return to normal filtration state.
In the utility model, in another embodiment of active carbon filter, UF ultrafiltration membrane filter also comprises a controller.This controller is for controlling the shutoff of described water intaking valve 7 and described blowoff valve 8.Concrete, controller is PLC.During backwash, controller switching is treated blowoff valve 8 and water intaking valve 7.A part of this filter element 1 of liquid reverse flow backwash after other filter element 1 filters, removes rapidly the filter cake on filtering layer surface, discharges after raffinate flows into the dirty pipeline of collection and discharges, and then closes blowoff valve 8, opens inlet valve, returns to normal filtration state.Described controller makes described filter element 1 carry out in turn backwash.During backwash, three filter elements 1 are in filtration condition, and a filter element 1 carries out backwash state.By A → B → C → D → A automatic wheel stream, undertaken, backwash finishes automatically to enter filtration condition, waits for program cycle next time, does not affect normal filtration water outlet during backwash.
Above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
