Description
Technical field
A kind of filter method of water and device are used for sewage disposal and increase water quality, and industrial circulating water and occasion such as swimming water purification etc. belong to the advanced treating field of water.
Background technology
Fabric filter be a kind of be the filter of filter element with the fiber filtering, compare with particulate filter, the specific area of fiber filtering is bigger, bigger Interfacial Adsorption is arranged and hold back suspension, fiber is soft simultaneously, when filtering, can realize Auto-regulating System of Density of Heavy Medium or, realize in-depth filtration dramatically, equipment effluent characteristics, retaining power, operation flow velocity all are greatly improved along the reasonable filter type that the water (flow) direction pore size filter diminishes gradually.
Industrial fabric filter commonly used mainly is divided into fiber ball filter, capsule squash type fabric filter and mechanical lifting formula fabric filter at present.Fiber ball filter is simple in structure, and fibrous nodules is a spheroid radially, near the fibre dense at ball center position, but can't realize loosening during backwash, and the dirt of holding back is difficult to thorough removing; Fibrous nodules easily runs off during with gas, water combined cleaning, and fibrous nodules is easily broken when cleaning with mechanical agitation.Capsule squash type fabric filter stretches the compacting filter material layer by air bag, and service life is short, and it is very frequent to change air bag.Mechanical lifting formula filter need be provided with mechanical lifting mechanism in the filter outside, drives removable orifice plate and fibre bundle and stretches, and this equipment countershaft part water-stop requires very tight, and seal is changed frequent, investment and operating cost height.Therefore, develop a kind of simple in structure, backwash easily, the filter of good sealing effect just seems very important.
Summary of the invention
The object of the present invention is to provide a kind of filter method and device of water, simple in structure, characteristics such as backwash easy, good sealing effect that this device has.
The present invention is achieved through the following technical solutions:
Characteristics such as the present invention utilizes the fixing long fibre in two ends as filtrate water to be filtered, and fiber filtering has the filter efficiency height, and the backwash resistance is little.
The long fibre filtering layer is made up of the multi beam layer, and each layer is at the top, or top and bottom is distance at the fibre bundle of water purification passage both sides to be shorter than water purification channel water open width wide, has guaranteed that fibre bundle can tensioning in the flushing process.
Long fibre is tightened up during filtration, makes that longitudinal void reduces between filament; Backwash duration fibre bundle is loosened, and makes the diastole of filametntary space and is in dither state, has quickened the process of backwash.
Backwash process uses the injection equipment that moves up and down to fiber jet with air or water from the water purification side, and fluid passes fibrage, will remove attached to the solids on the fiber, and the flushing process time is short, effective and water-saving.
Realize that long fibre tension and the mechanism that loosens are that the long fibre bottom fixes, its top is fixed on movably on the plate, the reverse side of the plate that is connected with fiber, and the realization that is connected with mechanism moving up and down moves up and down.
The movably plate that is connected with long fibre is connected with the flexible material that can be out of shape with filter housing, realizes the sealing of filter, prevents overflowing of sealing.
Realize that device of the present invention is made up of following mechanism at least: long fibre, long stapled bottom fixed mechanism, long stapled top fixed mechanism, the supporting mechanism of long stapled water purification STH, the water purification passage, former aquaporin, long fibre top fixed head, the reciprocating mechanism of fixed head, the flexible material that fixed head is connected with filter housing.
In filter process, filter is by former aquaporin, the long fibre filtering layer, and the filter element plural number that long fibre supporting mechanism and water purification passage are formed is disposed in the same filter side by side, and long fibre layer top fixed head is connected with a plurality of long fibre filtering layers unit.
The invention has the beneficial effects as follows the degree of tightness state that utilizes the plate control fibre bundle move up and down, help filtering or the carrying out of backwash; Backwash uses the injection equipment that moves up and down to fiber jet with air or water from the water purification side, and is simple in structure, the good and saving water of backwash effect; The plate that moves up and down is connected with the flexible material that can be out of shape with filter housing, realizes the sealing of filter, prevents overflowing of sealing, good sealing effect, and the life-span is long.

The specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Embodiment 1.
This example is the embodiment that recirculated cooling water is carried out advanced treating.Water filtering device as shown in Figure 1 is made up of 3 filter elements.Wherein the tension mode of fibre bundle is shown in Fig. 3-1.Former water enters the former aquaporin 2 of filter element through former water inlet 1, and meanwhile, reciprocating mechanism 7 drives long fibre fixed heads 6 and moves up, and the long fibre bundle is in tension.Long fibre bundle fixed head links to each other with flexible material 5 with filter housing, prevents overflowing of sealing.In the filter process, former water enters the inside of the long fibre supporting mechanism 3 of porous by long fibre 4 under action of pressure, enter water purification passage 8, and it is intrafascicular that the suspension in the former water is trapped within long fibre, and water purification is discharged by pure water inlet 9; During backwash, flushing water enters from the water purification passage, by the hole outflow of long fibre bundle branch support mechanism long fibre Shu Jinhang is washed, simultaneously, air duct 10 beginning bubbling airs are blown by 11 pairs of long fibres of aeration tube, make long fibre produce shake, stir backwashing water simultaneously.Filter efficiency has reached 92%, backwashing time 3min, and the backwash water amount is for handling 3.1% of the water yield.
This example is that the water after sewage disposal is handled carries out advanced treating.Filter process is identical with embodiment 1, when different is backwash, the injection equipment that utilization moves up and down passes through the hole of long fibre supporting mechanism to long fibre inject high pressure water at the water purification passage, can impel simultaneously the long fibre shake, the water after the backwash is discharged from former water inlet and pure water inlet respectively through former aquaporin and water purification passage.Treated, filter efficiency has reached 95%, and backwashing time 1.5min, backwashing water consumption handle 2.8% of the water yield.
This example is that the recirculated water to plant carries out filtration treatment.Filter process is identical with embodiment 1, when different is backwash, the injection equipment that utilization moves up and down passes through the hole of long fibre supporting mechanism to long fibre inject high pressure air at the water purification passage, make long fibre produce shake, and stirring backwashing water, backwashing water enters from the water purification passage, discharges by former water inlet from former aquaporin.Treated, filter efficiency has reached 89%, and backwashing time 3.5min, backwashing water consumption handle 3.6% of water.
Embodiment 4.
This example is the embodiment to the swimming-pool water advanced treating.Filter process is identical with example 1.Different is that filter is made up of 5 filter elements, and the tension mode of fibre bundle is shown in Fig. 3-2.Treated, filter efficiency has reached 98%, and backwashing time 2min, backwashing water consumption handle 2.5% of water consumption.
