Abstract
The invention provides a method which leads liquid surface, from top to bottom or from bottom to top, to sweep through a filter material layer when gas-water composite washing is used, thus leading mud adsorbed on the surface of the filter material to be thoroughly peeled off and washed away and drained out of a filter by cleaning water. The reinforced cleaning method provided by the invention can conveniently and thoroughly clean the filter-bed typed filters.
Description
Technical field
The present invention relates to the reinforcement of filter precoat cleaning performance.
Background technology
Filter bed filter, as quartz sand filtration device, fiber bundle filter, fibrous nodules (or comet filtrate) filter etc., cleaning method commonly used is the air-water combined cleaning.This method is that filter material layer is submerged in the water fully, closes with gas scouring, water backwash or air-water and washes.The weak point that this method exists is that the cleaning performance of filtrate is often not ideal enough, and the deposition of filter material layer meeting in the course of time seriously causes hardens.
Summary of the invention
The purpose of this invention is to provide a kind of method that is used for intensive filtration device filter material layer cleaning performance.
Be used to realize a kind of filtrate cleaning method of the object of the invention, it is characterized in that filter passes through the draining of filter or intake liquid level is moved inswept filter material layer from top to bottom or from bottom to top when cleaning, air relies on the liquid level be subjected to the air strong disturbance to wash away filter material surface strongly by filter material layer from bottom to top from the filter bottom, makes attached to the body refuse of filter material surface thoroughly to be stripped from and to take away discharge filter with cleaning current.
Method of the present invention can be used for cleaning fiber bundle filter, fibrous nodules (or comet filtrate) filter, quartz sand filtration device, charcoal filter, ion-exchanger, doughnut film filter etc.
Method of the present invention both had been applicable to pressure filter, also was applicable to gravity one.
Method of the present invention also can be used for the cleaning of other fluid filter of wet goods.
The method that reinforcement provided by the invention is cleaned can make things convenient for, up hill and dale bed filter be cleaned.
The specific embodiment
Describe the present invention in detail below in conjunction with accompanying drawing.
Fig. 1 fiber bundle filter liquid fluctuating cleans schematic diagram
Fig. 2 fibrous nodules (or comet filtrate) filter liquid fluctuating cleans schematic diagram
Fig. 3 granular filter material filter liquid fluctuating cleans schematic diagram
Figure 1 shows that the fiber-bundle filtering bed of material 5 liquid fluctuating cleaning processes. Rinse water inherent filtration device End opening 2 enters filter, flows from bottom to top in the fiber-bundle filtering bed of material 5, and liquid level 4 is from lower And upper the propelling, air enters from the air inlet pipe 7 that is arranged on the filter bottom and passes through air distributing device again 8 distribute a large amount of bubble 6 of generation, and bubble 6 enters 5 disturbances of the fiber-bundle filtering bed of material from bottom to top Clean subsurface fiber bundle media, and make liquid level strong to the strong perturbation action of liquid level generation Wash away fiber bundle media, the body refuse that is attached to filter material surface is stripped from and up hill and dale with rinse water Stream is taken away. Air is discharged from suitable for reading 1 of filter.
Figure 2 shows that fibrous nodules (or comet fiber filter) filter material layer 9 liquid fluctuating cleaning processes. Rinse water inherent filtration device end opening 2 enters filter, at fibrous nodules (or comet fiber filter) filter material layer Flow from bottom to top in 9, liquid level 4 advances from bottom to top, and air is from being arranged on the filter bottom Air inlet pipe 7 enter again to distribute by air distributing device 8 and produce a large amount of bubbles 6, bubble 6 from Lower and on enter 9 disturbances of fibrous nodules (or comet fiber filter) filter material layer and clean subsurface fibrous nodules (or comet fiber filter) filtrate, and liquid level is produced strong perturbation action liquid level is washed away strongly Fibrous nodules (or comet fiber filter) filtrate, make be attached to filter material surface body refuse more up hill and dale by Peel off and take away with cleaning current. Air is discharged from suitable for reading 1 of filter.
Figure 3 shows that granular filter material layer 10 liquid fluctuating cleaning process.Rinse water inherent filtration device end opening 2 enters filter, in granular filter material layer 10, flow from bottom to top, liquid level 4 advances from bottom to top, air enters to distribute by air distributing device 8 from the air inlet pipe 7 that is arranged on the filter bottom again and produces a large amount of bubbles 6, bubble 6 enters 10 disturbance of granular filter material layer from bottom to top and cleans subsurface granular filter material, and liquid level is produced strong perturbation action make liquid level wash away granular filter material strongly, make attached to the body refuse of filter material surface and be stripped from up hill and dale and take away with cleaning current.Air is discharged from suitable for reading 1 of filter.
