It passes through the materials (1) and (2) and is discharged to the outside, and has a large overstretching force compared to the N volume. As time passes, the scum accumulates on the surface of the bP material, making it impossible for the scum to form a cocoon for convenience, and once the scum becomes a solidified cake, it cannot be easily removed. It is described as an exclusively disposable filter. ゛To extend the service life of the filter, two filters can be installed in parallel so that they can be switched, and 7)' It is sufficient to perform the sludge removal work on the 1st filter and use the 21M filter alternately,
This method cannot increase the plowing rate of the filter as a whole above 50 cm, and it is a waste of time that increases the cost required for the filter by 1%.

It is an object of the present invention to continuously remove 7' slag while using the above-mentioned filter element for overworking, thereby extending the service life of the filter element. The filter element is rotatably supported in the casing, separated into a filtration zone and a regeneration zone, and 5j' filtration is carried out in the filtration zone and at the same time, slag is removed in the regeneration zone. This is accomplished by configuring it as such.

Embodiment 7 To explain with reference to the drawings, rLp shown in FIG.
<A long planar paper (1) and a long corrugated paper (lead paper) having a ridge line in the width direction are laminated, and a ridged portion at one end of the formed paper (2) is formed. and the trough at the other end are filled with an appropriate filler (3), (5) such as synthetic resin base or plaster, and the filter element (5) is wrapped around the boss (4) or shaft. As shown in Fig. 3, it is held rotatably by the prime mover (lo) and belt (uni) and housed in the casing (6), and the purge sector of the casing (6); play zone (8) and play zone (

As for 2>, paper or cloth made of various materials depending on the properties of the fluid to be treated, such as ceramic fiber paper or glass fiber paper, or gold (dark paper or other materials) can be used. It is also possible to remove bad odors at the same time as filtration by impregnating it with a filtration agent. Particularly when using materials with adsorption properties such as paper with activated carbon fine particles or activated carbon fiber paper, it is possible to remove odor at the same time as filtration. It is possible to adsorb active substances such as sulfur dioxide, nitrogen oxides, ozone, organic solvent vapors, or active substances contained in liquids such as dyes, detergents, nitrogen-based organic compounds, sulfur-based organic compounds, etc. To use wind as the regeneration fluid,
The suction material can be removed simultaneously with the slag.

As described above, the present invention rotates the filter rods (5), which have a very large filtration area compared to the volume, at a low speed within the casing (6), thereby achieving filtration and regeneration. In addition, since the +12 ability of light spectral regeneration is performed in an area less than 1/3 of the regeneration zone (9) and the filtering zone (8), the filter element (5) is )'tr: Use it for easy disposal only, or use two units in parallel for more than half of the time. 2-3 or more can be used in succession with 5j' overworking, especially J' of fluid with little slag') 5
It has the characteristic effect that over-processing can be carried out efficiently and at low cost. Of course, depending on the amount and nature of the slag in the fluid, the tXa removing fluid may be allowed to flow intermittently.

DETAILED DESCRIPTION OF THE INVENTION As shown in FIG. 1, a long planar furnace material (1) and a long corrugated furnace material (2) having ridge lines approximately in the width direction are laminated and welded,
Filler material (
3) As shown in (3), fill with a semi-fluid adhesive, or layer and bond the planar furnace material (1) and the corrugated furnace material (2) as shown in Fig. By crushing one end of the waves as shown in (3a) and filling the troughs of the waves at the other end with the filler (3), the peaks at the shoulder and the troughs at the other end of the corrugated furnace material (2) are separated. A filter element formed into a cylindrical shape by irrigating around the boss (4) or shaft or by rolling up only the furnace material as shown in Fig. 3 has already been patented in the United States on June 1, 1952. No. 2.599604 discloses a filter for disposing of feces. This filter element has a large number of small diameter holes extending from one end surface to the other end surface of the cylinder, and half of the small diameter holes are completely sealed (!
3), (3), and as shown in Fig. 4, the fluid flowing in from one end surface is false and wide, and the soaked furnace material (1), (
2) Because it is discharged to the outside through the water, it has a large capacity compared to the volume it occupies, but as it is used for protection, furnace slag gradually accumulates on the surface of the raw material, and eventually It becomes difficult to use, and the slag becomes cake-like and cannot be easily removed. Therefore, in the above-mentioned literature, it is described exclusively as a filter for use in toilet bowls. In order to extend the service life of this filter element, two filters can be arranged in parallel so that they can be switched, and while one filter is performing filtration work, the other filter element's It is possible to install a rack and use 2ii# filters alternately, but with this method, it is not possible to reduce the operation rate of the filter cap to more than 50%, resulting in an additional cost of 4. becomes. The purpose of the present invention is to constantly remove p-slag while using the above-mentioned filter element for filtration work, thereby improving the operating rate of the filter and extending the service life of the filter element. According to the invention, the filter element is rotatably supported in a casing, separated into a filtration zone and a regeneration zone, and is configured to perform filtration work in the filtration zone and simultaneously remove slag in the regeneration zone. This is achieved by To explain the embodiment with reference to the drawings, as shown in Fig. 1, a long planar filter paper (1) and a long corrugated base paper having ridge lines approximately in the width direction are laminated and bonded to form a corrugated filter paper (2). The peaks at one end and the valleys at the other end are filled with appropriate fillers 0) and (3) such as synthetic resin paste and plaster, and one end of the wave of the corrugated filter paper (2) is still filled as shown in Figure 2. As shown in (3a), filler material (3) is filled in the trough of the wave at the other end, and this is applied to the third
As shown in the figure, the filter element 0) wound around the boss (4) or shaft is connected to the driving force ff as shown in Figure 5.
1 (lo), is held rotatably by the belt (11) and stored in the casing (6), and the casing (6)'
This filter is separated into a filtration zone (8) and a regeneration zone (9) by a purge sector (7), and as shown in FIG.
A pipe (13) such as a duct for passing the furnace slag removing fluid (U4) is connected to the regeneration zone (9), and a 4S pipe C15) for passing the furnace slag removal fluid (U4) is connected to the regeneration zone (9). In the top view, (16) is a seal such as a rubber plate that prevents the fluid to be treated (12) from mixing with the slag removal body (14), and is a seal such as a rubber plate.
5) The circular surface is covered with a thin steel plate (17) to form 41R.
strengthen However, in FIGS. 1, 2, and 4, the direction of the wave ridge line does not necessarily have to be perpendicular to both end surfaces of the filter paper. For convenience, as shown in Figures 5 and 6, the filter element (5) is rotated at a relatively low speed in the filtration zone (8).
In the off-shore zone (8), the fluid to be filtered (12) is passed through the regeneration zone (9), and the slag 1 waste fluid (U4) is passed through the regeneration zone (9), preferably in opposite directions as shown by the arrows in the figure. The fluid to be treated (12) is filtered and discharged through the entire filter paper with an extremely wide area as shown by the broken line arrow (12) in Fig. 4, and in the regeneration zone (9), the fluid for removing slag (14) is
As shown by the broken line arrow (14) in the figure, the entire surface of the filter paper is passed in the opposite direction to efficiently remove the furnace slag. The slag removing fluid (14) accompanying this furnace p4 is discharged after removing the slag by an appropriate method such as passing it through water if it is a gas or using a sedimentation tank if it is a liquid. . In the above embodiments, filter paper was used as the furnace materials (1) and (2).
As the furnace material, paper or cloth made of various materials depending on the properties of the fluid to be treated, such as ceramic fiber paper or glass fiber paper, or wire mesh or other mesh, can be used. It is also possible to impregnate an odor agent to remove bad odors at the same time as filtration, especially when using materials with adsorption properties such as paper with activated carbon fine particles layered on one or both of the furnace materials or paper mixed with activated carbon fibers. At the same time, active substances contained in gases, such as sulfur dioxide, nitrogen oxides,
Contains ozone, organic solvent vapor, or liquid! Active substances such as dyes, detergents, etc. It is capable of adsorbing organic compounds, sulfur-based organic compounds, etc. In this case, hot air, hot water, etc.6 are used as the regeneration plate (14), and the adsorbed substance can be desorbed and removed at the same time as the furnace slag. As described above, the present invention is designed to drive and rotate the filter element (5), which has an extremely large filtration area compared to its volume, at a low speed within the casing (6), so as to simultaneously perform the filtration action and the regeneration, that is, the slag removal action. However, since the regeneration zone (9) can provide sufficient regeneration power with an area less than 1/3 of the filtration zone (8), the filter element (5) can be used as a dedicated filter as in the past. Effective over a long period of time without the drawback of not being able to use more than half of the time for filtration, since the furnace 4 and furnace slag removal can be performed alternately by using two units in parallel or by using two units in parallel. /4 or more for filtration work
It is necessary to use these two devices in succession, and it has a significant effect that allows efficient and inexpensive filtration of fluids with a small amount of slag. In addition, depending on the amount of slag in the fluid, the fluid for removing slag may be applied intermittently depending on the person's μ eye.
