Abstract

PURPOSE:To reduce the amt. of a liq. remaining after filtration and to improve the precision of the completeness test by the pressure holding method, by specifying the ratio of the cross-sectional area of a small gap between a protective plate on the liq. inlet side and the housing lid surface to the cross-sectional area of a liq. inlet. CONSTITUTION:The filtration system consists of a filter cartridge 7, wherein a plate filter unit 3 having a filter membrane 2 on the upper and lower sides of a supporting body 1 is laminated, and the housing 9. In the system, the ratio of the cross-sectional area Y of the liq. inlet passage 12 between the protective plate 8 on the liq. inlet side and the housing lid surface 13 to the cross-sectional area X of the liq. inlet is set at 0.7<=X/Y<=1.2. By this method, since a wide space for distributing the liq. need not be formed under the liq. inlet, a large amt. of the liq. is not accumulated, and the remaining liq. is reduced. In addition, as the space volume on the primary side in the housing is small, the precision of the completeness test by the pressure holding method can be improved.

Conventionally, as shown in FIG.
A stack of flat plate type filtration units 3 having a filtration unit 3 and a central opening 6. In the filter cartridge 1 of the flat plate laminated type from which the filtrate is taken out from the core 15 through the communication port 14 of the core 15, a chamber 10 exists between the enka entry side protection plate 8 and the housing 9 of the filter cartridge, and the filtrate is filtered. The liquid was supplied to the peripheral portion 4 between the housing 9 and the stacked filtration units 3.

[Problems to be Solved by the Invention] However, since the housing 9 of the conventional filter cartridge cartridge has a large space in the chamber 10, there is a problem that there is a lot of liquid remaining in the housing 9 when filtration is completed, or that the filter cartridge is There was a problem in that the measurement accuracy was insufficient in the integrity test using the pressure hold method, which was performed before and after filtration.

At the end of filtration, the residual liquid in the chamber 10 was initially forced to be filtered by air pressure, but at that time, not only the liquid but also the pressurized air passed through the filtration membrane, resulting in contamination of the filtrate and damage to the filtration membrane. In some cases, due to problems such as shortened service life, the final pneumatic pumping is not performed, and the liquid in the filter cartridge is left as it is to complete the il passing operation.

Therefore, since the liquid remains in the housing 9 that houses the filter cartridge, it is desired to reduce the amount of residual liquid. Further, in a complete test using the pressure hold method, the volume of the primary side of the filter cartridge is large, and as mentioned above, the measurement accuracy is not good, so there was a desire to reduce the volume of the primary side as much as possible.

[Means for Solving the Problems] The above object of the present invention is to stack flat plate-type 11tilJ units having filtration membranes on the upper and lower sides of a support, take in liquid from peripheral openings of the filtration units, and remove the filtration membranes. In a filtration system consisting of a filter cartridge and a housing, through which the filtrate is taken out from the central opening, the cross-sectional area Y of the small gap of the liquid intake channel between the liquid inlet side protection plate of the filter cartridge and the housing lid surface This is achieved by a filtration system characterized in that 0.7≦÷≦1.2 for the cross-sectional area X of the liquid intake port.

In the present invention, the cross-sectional area Y of the small gap serving as the liquid intake channel between the liquid inlet side protective plate of the filter cartridge and the housing lid surface is 0.7 with respect to the cross-sectional area X of the liquid inlet.
≦−'! -<1.2 means that the lid surface of the housing of the flat plate type 7i filter cartridge is placed on the top surface of the protective plate on the liquid inlet side, without providing a chamber where the liquid enters a wider chamber once from the main inlet as in the conventional case. A small gap between the housing lid surface or the inner surface of the housing on the enka inlet side and the upper surface with a passage area wider than that of the liquid inlet side protective plate is formed as a liquid intake flow path, for example, in a radial or planar manner. The method of distributing the filtrate around the periphery of the filtration unit is close to the area of the liquid intake port and has a somewhat lower flow resistance.

As described above, in the present invention, there is no need to provide a wide space for distributing the liquid under the liquid intake port of the filter cartridge, and either side may be close between the liquid inlet side protective plate and the housing cover surface. By setting the cross-sectional area Y of the small gap serving as the liquid intake flow path to 0.7≦-≦1.2 with respect to the cross-sectional area X of the liquid intake port, there is no accumulation of liquid, resulting in a filtration system with less residual liquid. can be provided. Similarly, since the primary space volume within the housing of the filter cartridge is small, the accuracy of the complete test using the pressure hole method can be improved.
