〈先行技術と問題点〉
原液を限外濾過、逆浸透濾過等によつて処理す
る濾過装置として積層式濾過装置が公知である。<Prior Art and Problems> A laminated filtration device is known as a filtration device that processes a stock solution by ultrafiltration, reverse osmosis filtration, or the like.

プレートである。 Figure 4 shows a conventional laminated filtration device;
As shown in the figure, a unit u' is attached to both sides of a membrane support plate 1' with membranes 2' and 2' to form a permeate passage between the membrane and the support plate, and is connected via spacers 3', . . . Laminated,
A concentrate passage is provided between the units u' and u' by this spacer 3', concentrate passage holes 13i' and 13o' are provided to communicate with these concentrate passages, and a permeate exchange pipe is provided in each unit leading to the permeate passage. f', . S', ... are separating plates.
この濾過装置による原液の処理要領は、原液流
入口から原液を供給し、この原液がユニツト間の
原液通路を流れる間に、原液中の溶媒をユニツト
の膜を経て透過させ、この透過液を透過液通路を
経て透過液取出管から取出すことにある。 The procedure for processing the stock solution using this filtration device is to supply the stock solution from the stock solution inlet, and while this stock solution flows through the stock solution path between the units, the solvent in the stock solution is permeated through the membrane of the unit, and this permeate is passed through. The purpose is to take out the permeate from the permeate take-out pipe through the liquid passage.

εnax＝Pl2／８・６／t2 −
で与えられる。 By the way, the stock solution pressure is several times in the case of ultrafiltration.
Kg/cm 2 , and particularly when the filtration device starts or stops operating, a transient high pressure acts on the membrane support plate. However, in conventional laminated filtration devices, the membrane support plate has a mechanical structure that can be supported at both upper and lower ends to withstand this high pressure load, and the maximum bending strain ε nax
is generated at the center of the support plate, and is given by ε nax =Pl 2 /8·6/t 2 − where P is the pressure, l is the length of the support plate, and t is the thickness of the support plate.
而して、Ｐが相当に高圧であるために、支持板

においてｌが２分の１になつて最大曲げ歪εmax
を４分の１になし得るに過ぎない。 Since P is a considerably high pressure, it is necessary to increase the thickness t of the support plate considerably, which inevitably results in an increase in the size of the laminated unit. Conventionally, a laminated filtration device in which a permeate passage hole is provided between the above-mentioned stock solution passage holes 13i' and 13o' is also known. In equation 1, when l is halved, the maximum bending strain εmax
can only be reduced to one-quarter.
