Description

Deep filtration cartridge {deep bed filter cartridge}

The present invention is a cylindrical media storage case in which raw water is introduced and discharged; A fiber bundle for filtering the raw water, the filter material bundle having both ends bound by an auxiliary string; It is coupled to both ends of the filter storage case, the auxiliary straps of the filter bundle is coupled to a plurality of coupling device configured to hold a plurality of the filter bundle inside the filter storage case, characterized in that deep filtering of the raw water in the raw water It is about depth filter cartridge to make.

The present invention for the deep filtration is to deeply filter the density or size of the filter media by the means of interpolating the bundle of different lengths, using a conical filter case, or by pressing means for compressing the filter case Relates to a cartridge.

In general, the operation of the filtration system consists of filtration and backwashing.

Filtration refers to the operation of separating the suspended solids and liquid particles in the fluid in a broad sense, and in the narrow sense to separate the solid particles in the liquid, such as water, the liquid mixture containing the solid particles through the porous filter medium, Solid means deposition on the surface or inside of the filter medium, and liquid means permeation to separate the two.

Hereinafter, the filtration of the present invention will be described by taking filtration in a narrow sense as an example, but the scope of the present invention is not limited thereto.

The narrow filtration means a filtration layer filled with suspended solids such as fine particles, algae, etc. in water of a liquid (hereinafter referred to as 'raw water') that needs to be filtered to contain suspended solids (hereinafter, referred to as 'filtrate'). In the following, abbreviated as "extra layer"), a process of entrapment and removal by physical and chemical operations such as diffusion, interception, inertia collision, precipitation, aggregation and adsorption is performed.

Sedimentation of suspended solids occurs in the filtrate filled with the filter medium during the filtration process, thereby reducing the air gap of the filtrate, thereby generating filtration resistance.

Since the filtration resistance lowers the filtration efficiency, the filter medium in the filtrate needs to be backwashed.

Therefore, the performance of the filtration system is evaluated by the filtration and backwashing processes, which are determined in detail by the efficiency of removing the suspended solids and the size of the removal particle size, the filtration rate, the filtration duration, the backwash frequency, the backwash quantity, and the backwash time. .

The media is mainly used for particulate matter such as sand, anthracite, activated charcoal, clay, crushed magnetite, garnet, inert media, etc., but these media have a problem that the filtering device and the installation area are very large.

In addition, since the trapping space of the underwater particles during filtration is not only limited to the surface layer, but also has a fixed pore structure due to the characteristics of the media, air gap reduction or void occlusion of the suspended solids in the water frequently occurs, Since the loss is increased, the backwashing frequency of the filter medium in the filtrate is increased, and the filtration rate is reduced.

In order to solve the problems of the conventional method, a pre-rotated backwash precision filtration device (application number: 10-1997-023068) has been introduced, and the invention is a fiber yarn filter radially attached to the side of the porous drum rotor. One end is attached to the rotary spring fixed to the pressure vessel wall, and the filter is filtered and backwashed through the reverse and forward rotation of the drum.

However, the filtration apparatus is severely damaged by the fiber yarn filter due to friction, and the particle capture space is small, so that the filtration duration is short, the frequency of backwashing is frequent, and it is difficult to cope with fluctuations in water quality of raw water.

Then, a permanent filtration device (application number: special 1998-0405542) having a variable filter layer which is a filtration device that is compressed and filtered by the feed pressure of the raw water, and is relaxed by back pressure by the pressurized air and backwashing water pressure. However, this method also suffers from entanglement and damage of the fibrous fiber, which is a medium in the process of repeated compression and relaxation of the piston, and because of the formation of a single layer during the filtration operation, the trapping time and the amount of particle trapping are small. Frequently, the frequency of washing is not high, and the filtration rate is not large, and it is difficult to cope with changes in the quality of the feed water.

In order to solve the above problems, the present invention has a long life of the fiber yarn filter, a large particle capture space, long filtration duration, easy backwashing, easy to cope with the fluctuations of the water quality of the deep water filter cartridge The purpose is to provide.

That is, the present invention aims to provide a deep filtration cartridge in which the size of the trapping particles for each site is different because the pore density of the discharge portion and the inlet portion is different.

In addition, an object of the present invention is to provide an in-depth filtration cartridge that is easy to wash the suspended matter during backwashing.

As shown in the drawings, the present invention is largely composed of a filter housing case 3, a filter bundle 1, and a filter fixing device 6.

Hereinafter, the present invention will be described in detail with reference to FIG. 1.

The media storage case 3 of FIG. 1 is a cylindrical case into which raw water is introduced and discharged.

The filter housing case 3 is not necessarily limited to a cylindrical shape.

The raw water means water in which suspended matter (sludge) is contained in the water and needs to be purified.

The filter media bundle (1) is composed of a fiber bundle that both ends are tied by the auxiliary string (12).

As the raw water flows into the fiber bundle, suspended matter in the water is filtered through the fiber to allow the water to be purified.

The filter medium fixing device 6 is a porous plate coupled to the inlet and the outlet of the filter housing case 3 and is divided into an inlet filter device 61 and an outlet filter device 62.

The filter bundle (1) is a plurality of interpolation in the interior of the filter housing case (3) is fixed by coupling the auxiliary strap 12 to the filter medium (6).

The filter medium fixing device 6 is preferably made of a porous plate so as not to block the passage of raw water.

In the present invention, the media storage bundles 3 having different lengths are equally interpolated in the media storage case 3 to form a media layer.

As a result, end portions of the long filter bundle are scattered to form a filter layer at the inlet of the filter storage case 3, and the filter bundles are compressed to form the filter layer toward the discharge part, thereby changing the filter density of the inlet and the discharge part.

At this time, one end of the filter media bundle (1) is connected to the inlet filter medium fixing device 61 by hanging the auxiliary string 12, the other end of the filter medium bundle (1) discharge part filter medium (62) It is desirable to connect so that the density of the filter medium linearly from the outlet to the outlet.

According to the configuration of the present invention described above, as the density of the filter, that is, the filling rate of the filter, increases from the inlet to the outlet, and the size of the pores capable of capturing the suspended matter becomes smaller toward the outlet, a large particle of suspended matter is caught in the inlet. In the discharge section, small particles of suspended matter are caught.
