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, in the fiber-bundle filtering bed of material 5, 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 5 disturbances of the fiber-bundle filtering bed of material from bottom to top and cleans subsurface fiber bundle media, and liquid level is produced strong perturbation action make liquid level strongly wash away fiber bundle media, make the body refuse that is attached to filter material surface be stripped from up hill and dale and take away with cleaning current. 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, in fibrous nodules (or comet fiber filter) filter material layer 9, 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 9 disturbances of fibrous nodules (or comet fiber filter) filter material layer from bottom to top and cleans subsurface fibrous nodules (or comet fiber filter) filtrate, and liquid level is produced strong perturbation action make liquid level strongly wash away fibrous nodules (or comet fiber filter) filtrate, make the body refuse that is attached to filter material surface be stripped from more up hill and dale 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.
Claims (1)
1. filtrate cleaning method, it is characterized in that: filter draining or water inlet by filter when cleaning moved inswept filter material layer from top to bottom or from bottom to top with liquid level, air passes through filter material layer from bottom to top from the filter bottom, the liquid level that dependence is subjected to the air strong disturbance washes away filter material surface strongly, make attached to the body refuse of filter material surface and thoroughly be stripped from and take away discharge filter with cleaning current, air is from the discharge suitable for reading of filter.
