Fig. 1 has shown the structure principle chart in the utility model with the active carbon filter of backwashing function.As shown in Figure 1, this active carbon filter comprises intake tunnel 4, filter element 1, exhalant canal 5, the drain outlet 6 of at least two.
One end of intake tunnel 4 is connected with water source, and water source can flow in this active carbon filter from intake tunnel 4.
Each filter element 1 has water inlet 11 and delivery port 12.In each filter element 1, be provided with active carbon filter core 13.Adopt the special-purpose shell activated carbon of water treatment, to the organic matter of flowing through in seawater, colourity, smell, turbidity is effectively adsorbed, reduced to the harmful substances such as heavy metal ion, makes import seawater meet the requirement of system water inlet technology.Concrete, filter element 1 has the inner chamber of a hollow, and active carbon filter core 13 is arranged in this inner chamber.The water inlet 11 of filter element 1 is arranged on the top of this filter element 1.The delivery port 12 of filter element 1 is arranged on the bottom of this filter element 1.
Between the water inlet 11 of each filter element 1 and the other end of intake tunnel 4, be provided with the water intaking valve 2 corresponding with filter element 1.Between each water intaking valve 2 and the water inlet 11 of filter element corresponding thereto 1, be provided with a blowdown pipeline 14.Between each water intaking valve 2 and the water inlet 11 of filter element corresponding thereto 1, be provided with a blowdown pipeline 14.
Concrete, in the present embodiment, active carbon filter comprises an intake tunnel 4, four filter elements 1, exhalant canal 5, drain outlet 6, four water intaking valves 2, four blowoff valves 3.
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 intake tunnel 4, then enter filter element 1 from the water inlet 11 of filter element 1, by completing filtration after active carbon filter core 13.The clean water completing after filtration flows to exhalant canal 5 these active carbon filters of discharge from the delivery port 12 of filter element 1 again.
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 6 discharges active carbon filters from the water inlet 11 of filter element 1 from drain outlet.
In the present embodiment, the precision of active carbon filter is 1 to 3mm, and the flow of active carbon 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.
Active carbon 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, reclaim high value solid particle wherein., the utility model adopts the special-purpose shell activated carbon of water treatment, to the organic matter of flowing through in seawater, and colourity, smell, turbidity is effectively adsorbed, reduced to the harmful substances such as heavy metal ion, makes import seawater meet the requirement of system water inlet technology.
Backwash 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.
In the utility model, in another embodiment of active carbon filter, active carbon 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.
