Abstract

PURPOSE:To eliminate the apprehension of by-passing the raw liquid due to the deterioration of sealability by burying the reinforcement plate to prevent the elactic deformation of elastic frame in the inside of the middle part between the raw liquid supply/discharge hole in the elastic frame of ceramic element and a ceramic plate. CONSTITUTION:Raw liquid spacers 30 provided with longitudinal through-holes 31 for supplying raw liquid which reach to the raw liquid supply/discharge holes 13 and permeated liquid spacers 20 provided with numerous latitudinal permeated liquid discharge holes 26 are closely stuck on both side of ceramic element 10 in which ceramic plates 11 are fixed on the elastic frame 12 provided with the raw liquid supply/discharge holes 13. The reinforcement plate 18 to prevent the elastic frame 12 form elastic deformation is buried in the inner part of the middle part between the raw liquid supply/discharge holes 13 of the elastic frame 12 and the ceramic plate 11. As a result, the apprehension of by-passing raw liquid due to the deterioration of sealability as well as the reduction of flow passage area of film surface are eliminated, and the performance of filtration is improved as a whole.

(Prior art) Filtration elements such as polymer membranes have traditionally been used for ultrafiltration and precision filtration of liquids, but among these, flat polymer membranes, typically the plate-and-frame type, are There is a drawback that backwashing cannot be performed because the strength of the membrane itself is low. For this reason, the inventors of the present invention
As shown in the publication, we first invented a backwashable ceramic element in which a thin porous ceramic flat plate was bonded to an elastic frame with approximately the same thickness, and this was laminated together with a stock solution spacer and a permeate spacer. Developed a liquid separation device. However, in such a liquid separation device, it is necessary to extend the vertically elongated stock solution supply hole formed in the stock solution spacer to the stock solution supply/discharge hole formed in the elastic frame of the ceramic element. A portion where no pressing force is applied inevitably occurs on the frame, reducing sealing performance, and there is a risk that the stock solution may leak to the permeate side between the ceramic element and the permeate spacer.

Therefore, in order to prevent the deterioration of sealing performance, the present inventors
We have previously invented a liquid separator that solves this problem by protruding a large number of ribs from the elastic frame adjacent to the stock solution supply and discharge hole, and have already filed an application as Japanese Patent Application No. 313043/1982. However, in the case of this prior invention, the membrane surface flow path area decreases by the cross-sectional area of the ribs, which tends to increase pressure loss, and there is also a concern that the ribs become obstructions in the flow path, leading to blockage. there were.

(Function) The device configured as described above guides the stock solution supplied from the stock solution inlet (7) to the stock solution spacer (30) via the stock solution supply discharge hole (13), and the vertically long stock solution supply through hole ( 31
) of the ceramic element OI through the ceramic plate (
11) to perform filtration of the stock solution, and the permeate is collected by the permeate spacer (20) and taken out from the permeate discharge hole (26). It is similar to the separation device, but in the present invention, a reinforcing plate (1
8) prevents deformation of this portion of the elastic frame (12), and due to its rigidity, the ceramic element qω and the permeate spacer (20) come into close contact with each other to reliably seal this portion. Therefore, the stock solution flowing through the stock solution supply and discharge hole (25) of the permeate spacer (20) is transferred to the permeate solution discharge hole (25).
6) is reliably prevented, and unlike the prior invention, there is no lip etc. that protrudes inside the stock solution supply hole (31) of the stock solution spacer (30).
A sufficient membrane surface flow path area is ensured, and the stock solution is guided to the surface of the ceramic plate (11) without any hindrance. As a result, as shown in the graph of FIG. 6, the liquid separator of the present invention can significantly reduce pressure loss compared to the old type liquid separator and the liquid separator of the prior invention. .

In addition, in this embodiment, the ends of each permeate discharge hole (26) of the permeate spacer (20) are extended laterally and communicated with each other through a vertical groove (27) formed on the back surface. Therefore, this permeate flows smoothly from the permeate discharge hole (26) through the groove (27), collects at the lower end thereof, and is taken out from there through the permeate discharge hole (14) of the ceramic element OI, etc. Ru. The cross-sectional area of the permeate flow path at this time is much larger than that of conventional ones, so flow path resistance can be kept to a minimum, and these permeate discharge holes (
Since the end of 26) is formed relatively thin, it is possible to reliably press the elastic frame (12) of the ceramic element 0ω in contact with this part to ensure a complete seal with the stock solution spacer (30). can.

(Effects of the Invention) As is clear from the above description, the present invention includes embedding a reinforcing plate inside the intermediate portion between the raw solution supply/discharge hole of the elastic frame of the ceramic element and the ceramic plate to prevent elastic deformation thereof. This improves sealing performance, eliminates the risk of the stock solution bypassing to the permeate side, and eliminates protrusions into the stock solution supply hole of the stock solution spacer to improve flow path blockage while securing the membrane surface flow path area. However, at the same time, the device succeeded in reducing the pressure loss inside the device, so it will greatly contribute to the development of industry as a liquid separation device that eliminates the problems of conventional devices.
