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 in the utility model with the purpose ceramic-film filter of backwashing function.As shown in Figure 1, this purpose ceramic-film filter comprises the filter element 1 of at least two.In the present embodiment, this purpose ceramic-film filter comprises four filter elements 1.In each filter element 1, be provided with ceramic membrane filter core 13.Ceramic element, English name is ceramic cartridge, be mainly used in to drinking water filter, antibacterial and activation processing, heavy metal ion in the water of filtering simultaneously, harmful chlorine residue and suspended contaminant, organic chemicals, color and peculiar smell, by being used this filter core can filter out the drinking water that reaches certain standard for drinking.Both can be applicable to the industries such as water purifier, bottled water and quality classification water supply, also can be applied to water quality to be supplied with other occasion of corresponding requirements.
Each filter element 1 has water inlet 11 and delivery port 12.Concrete, the water inlet 11 of filter element 1 and delivery port 12 are arranged on the bottom of described filter element 1, and described air bleeding valve 14 is arranged on the top of described filter element 1.The water inlet 11 of each filter element 1 is provided with a water intaking valve 2 corresponding thereto.Water intaking valve 2 is for the water that enters of controlled filter unit 1.When water intaking valve 2 is opened, need water to be filtered to enter the filter element corresponding with this water intaking valve 21 by water intaking valve 2.Each filter element 1 is provided with an air bleeding valve 14, and this air bleeding valve 14 is for discharging the gas of ceramic membrane inside.Delivery port 12 in each filter element 1 is connected.Filter also comprises and filter element 1 blowoff valve 3 one to one mutually, and described blowoff valve 3 is arranged between the water inlet 11 and water intaking valve 2 of filter element 1 corresponding thereto, blowoff valve 3 and water intaking valve 2 conducting separately of each filter element 1.
When filter element 1 is during in filtration condition, the water intaking valve 2 corresponding with this filter element 1 opened, and the blowoff valve 3 corresponding with this filter element 1 cuts out.Need the water filtering to flow in water intaking valve 2 from former water inlet 4, then enter filter element 1 from the water inlet 11 of filter element 1, by completing filtration after ceramic membrane filter core 13.The clean water completing after filtration exports 6 these purpose ceramic-film filters of discharge again from delivery port 12 flow direction filters of filter element 1.
When filter element 1 is during in backwash state, the water intaking valve 2 corresponding with this filter element 1 closed, and the blowoff valve 3 corresponding with this filter element 1 opened.At least one in remaining filter element 1 is in filtration condition.The delivery port 12 that flows to the filter element 1 in backwash state from the clean water flowing out in filtration condition, carries out backwash to the filter element 1 in backwash state, and from sewage draining exit 5, discharges purpose ceramic-film filter from the water inlet 11 of filter element 1.
In the present embodiment, the precision of purpose ceramic-film filter is 0.1 μ m to 200 μ m, and the flow of purpose ceramic-film filter is 1t/h to 100t/h.Water intaking valve 2 and described blowoff valve 3 are respectively two pass ball valves.Water intaking valve 2 and described blowoff valve 3 are a tee ball valve.
Purpose ceramic-film 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.The influent turbidity of purpose ceramic-film filter is lower than 150Um, delivery turbidity is less than 5Um, and suspension visual in the seawater of flowing through, floccule, marine alga, silt and not visible gelatin body are effectively adsorbed, and filters, reduce turbidity, make import seawater meet the requirement of system water inlet technology.
In the utility model, in another embodiment of purpose ceramic-film filter, purpose ceramic-film filter also comprises a controller.This controller is for controlling the shutoff of described water intaking valve 2 and described blowoff valve 3.Concrete, controller is PLC.During backwash, controller switching is treated blowoff valve 3 and water intaking valve 2.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 3, 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.
In a preferred embodiment, when the pressure reduction between the import and export of described filter element 1 reaches certain value, described controller turn-offs the water intaking valve 2 of this filter element 1 and opens the blowoff valve 3 of this filter element 1.When liquid passes through 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 12 of each filter element 1 is also circumscribed with a cleaning apparatus, and when the water intaking valve 2 of filter element 1 is closed, described cleaning apparatus passes into clean gas flow to the delivery port 12 of described filter element 1.Clean fluid can be mixed for liquid pressing contracting air.The filter cake that utilizes the outside clean fluid accessing 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, inlet pressure when kickback pressure arrival recoil fluid, open rapidly blowoff valve 3, there is liquid: (gas) presses pulse, remove rapidly the filter cake of cartridge surface, then close recoil fluid inlet valve, close blowoff valve 3, open material inlet wealthy, open outlet valve, return to normal filtration state.
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.
