の精製に用いられている。 BACKGROUND ART Conventionally, so-called spiral modules, in which a reverse osmosis membrane or an excess membrane is spirally wound to form a spiral element and the spiral element is housed in a housing, have been used for purifying various solutions.

つて処理が全く困難になるなどの欠点を有してい
る。 However, in conventional spiral modules, the liquid to be treated tends to accumulate in the gap between the spiral element and the housing. For example, when processing a perishable solution such as sugar solution, the liquid to be treated spoils in the gap, and the antibiotic solution In this case, the solute becomes heterogeneous in the gap, damaging the membrane, degrading the quality of the processing solution, and sometimes clogging, making the processing completely difficult. .

This forms a spiral membrane 2, and the upper part thereof is covered with an exterior body 3. In order to prevent the spiral membrane 2 from protruding, a telescope stop 5 having several radial bodies 4 is attached to one end of the spiral membrane 2. These permeated water collection pipe 1, spiral membrane 2, exterior body 3, and telescope stopper 5 form one spiral element 6, and each permeated water collection pipe 1 is connected with a connector (not shown). , a plurality of spiral elements 6 are loaded in the housing 7. A gap 8 is formed between the outer periphery of the spiral element 6 and the inner periphery of the housing 7, and this gap 8 is closed with a brine seal 9 provided around the telescope stopper 5.

水管１を介してハウジング７外に取り出す。 When processing a liquid to be treated in a spiral module having such a structure, the liquid to be treated is passed through one side of the housing 7, but as shown by the arrow in FIG. 5
A part of the liquid to be treated passes between the radial bodies 4 and enters the spiral membrane 2, and a part of the liquid to be treated passes between the membranes of the spiral membrane 2 and reaches the next spiral element 6, and the other part of the liquid to be treated is The permeated water passes through the spiral membrane 2 and becomes permeated water, which is collected in the permeated water collection pipe 1 . In this way, the liquid to be treated passes through the spiral element 6 one after another, and the liquid to be treated that has not passed through the spiral membrane 2 is taken out from the other side of the housing 7 as a non-permeated liquid, and the liquid that has passed through the spiral membrane 2 is taken out from the other side of the housing 7. is taken out of the housing 7 as a permeate through the permeate collection pipe 1.

異質化等の種々の障害が生じる。 Since the conventional spiral module has the structure explained above, there is no flow of liquid in the gap 8, and therefore, when the liquid to be treated enters the gap 8, it stays as it is, leading to the above-mentioned spoilage. Alternatively, various disorders such as heterogeneity may occur.

パイラルモジユールに関する。 The present invention solves such drawbacks in the conventional spiral module, and consists of a spiral element having a telescopic stop at one end of the spiral membrane, which is loaded into a housing, and is formed by the outer periphery of the spiral element and the inner periphery of the housing. In the spiral module, the permeate liquid and the non-permeate liquid are obtained through the spiral membrane by closing the gap with a brine seal provided around the telescope stopper and allowing the liquid to be treated to flow in from one side of the housing. The present invention relates to a spiral module characterized in that a communication hole is provided in the telescope stop to allow a portion of the liquid to be processed to flow through the gap that is closed with a seal.
以下に本考案を図面に基づいて詳細に説明す

と同じなので説明を省略する。 FIG. 4 is an enlarged longitudinal cross-sectional view of a main part of an example of an embodiment of the present invention, and FIG.
This is a longitudinal sectional view taken along the line B', and as shown in FIGS. 4 and 5, the telescope stopper 5 of the present invention is provided with one or more communication holes 10. The other parts are the same as the conventional spiral module, so the explanation will be omitted.

敗等を効果的に防ぐことができる。 In this way, in the spiral module of the present invention, the communication hole 10 is formed in the telescope stopper 5, so that a part of the liquid to be processed flows through one side of the housing 7 as shown by the arrow in FIGS. As shown in the figure, the flow passes through the communication hole 10 and flows into the gap 8.
Therefore, the liquid to be treated does not remain in the gap 8, and the liquid to be treated does not deteriorate or become heterogeneous during operation of the spiral module. Furthermore, even when the spiral module is suspended, by introducing extruded water from one side of the housing 7, the entire liquid to be treated in the housing 7, including the gap 8, can be replaced with extruded water. It is possible to effectively prevent spoilage of treated water.
本考案における通流孔１０は隙間８に被処理液

１０が閉塞するので好ましくない。 Since the communication hole 10 in the present invention is opened to allow the liquid to be processed to flow through the gap 8, the opening location thereof is not limited to the telescope stopper 5 as in the present invention, but may be opened in the brine seal 9, for example. It is also possible. However, since the brine seal 9 is generally made of a relatively flexible material such as synthetic rubber or natural rubber, even if the communication hole 10 is provided in this portion, the communication hole 10 will be blocked due to deformation of the brine seal 9, so this is not preferable. do not have.
次に通流孔１０の大きさについて説明すると、
スパイラルモジユールの本来の目的は被処理液を
加圧下の状態でスパイラル状膜２に通過させるの
であるから、通流孔１０が大きすぎると、あるい

ラルモジユールの本来の目的を達し得なくなる。
また通流孔１０の大きさが小さすぎると隙間８を
通れる被処理液の流量が低下して本考案の目的を
達し得なくなる。 Next, the size of the communication hole 10 will be explained.
The original purpose of the spiral module is to allow the liquid to be processed to pass through the spiral membrane 2 under pressure, so if the flow holes 10 are too large, or even if the flow holes 10 are small, they may be opened too many times. Then, most of the liquid to be treated passes through the flow hole 10, the gap 8, and then the flow hole 10 of the next spiral element 6, and the gap 8, making it impossible to achieve the original purpose of the spiral module described above.
Furthermore, if the size of the communication hole 10 is too small, the flow rate of the liquid to be treated that can pass through the gap 8 will decrease, making it impossible to achieve the object of the present invention.
本考案の通流孔１０の全断面積については、ハ
ウジング７に通流させる全体の被処理液の流量の
１〜10％の流量の被処理液が通流孔１０に流れる

％以下では本考案の目的を達し得ず、また全体の
流量の10％以上の被処理液を通流孔１０に通流さ
せると、スパイラルモジユールが本来有している
既定の透過液の採取量が低下するので好ましくな
い。 Regarding the total cross-sectional area of the communication hole 10 of the present invention, the total cross-sectional area is such that the liquid to be treated flows through the communication hole 10 at a flow rate of 1 to 10% of the flow rate of the entire liquid to be treated flowing through the housing 7. It is appropriate to determine. That is, the flow rate of the liquid to be treated flowing into the communication hole 10 is 1 of the total flow rate.
If the flow rate is less than 10%, the purpose of the present invention cannot be achieved, and if more than 10% of the total flow rate of the liquid to be treated is passed through the flow hole 10, the predetermined permeate collection that the spiral module originally has will not be possible. This is not preferable because the amount decreases.

のを防止することができる。 Note that, depending on the type of spiral module, the telescope stopper 5 may be attached in reverse as shown in FIG. Even in this case, by opening the flow hole 10 in the telescope stopper 5, it is possible to generate a flow of the liquid to be treated in the gap 8 as shown by the arrow, and to prevent the liquid to be treated from staying in the gap 8. can do.

る。 As explained above, the spiral module of the present invention has the communication hole 10 in the telescope stopper 5, so that the liquid to be treated is always kept in the gap 8 where the liquid to be treated stays in the conventional spiral module. The housing 7
By flowing the extruded water from one side, the liquid to be treated in the gap 8 that has flowed in immediately before the stoppage can be easily replaced with the extruded water. figure,
Various troubles caused by spoilage and heterogeneity of the liquid to be treated occurring in the gap 8 can be effectively prevented.
