Filtrating discharge pipe 9 is discharge pipes from the filtrating of the secondary side discharge of film module 3, is configured in the top of film module 3.Filtrating discharge pipe 9 is along the first module column 3a and the second module column 3b, and the cylindrical duct that the direction that promptly forms a line along film module 3 (directions X) is extended is configured in the position intermediate corresponding to the film module that is set up in parallel on the Y direction 3.Filtrating discharge pipe 9 can be made up of a pipe, also can on direction of principal axis, connected and is constituted by many pipes.In this embodiment, connect by three pipes and constitute corresponding to unit 2a～2c.
As shown in Figure 2, be provided with the outlet 9a that discharges filtrating in one distolateral (Fig. 1 left side) of filtrating discharge pipe 9, outlet 9a is connected with not shown filtrate tank.And; As shown in Figure 3; Filtrating discharge pipe 9 another distolateral (right side among Fig. 1) is closed; The inflow entrance 5a of outlet 9a and the stoste supply pipe 5 of filtrating discharge pipe 9 is in identical direction upper shed, and on the short transverse of filter 1, is located along the same line basically with the inflow entrance 5a of stoste supply pipe 5.
As shown in Figure 8, on each stoste arm 7, be connected with air supply pipe 15.Air supply pipe 15 is supplied with compressed air (below be called air) to stoste arm 7, through the air of being supplied with by air supply pipe 15, the outstanding absurd creature that accumulates in the hollow-fibre membrane 30 is got rid of through bubbling (エ ア バ Block リ Application グ).Air supply pipe 15 is responsible for 17 with air feed and is connected, and is responsible on 17 being connected with not shown compressor etc. at air feed.Bubbling running (エ ア バ Block リ ン グ ?translocation) will filtrate through the discharge pipe 9 of filtrating from the secondary side of film module 3 air supply or nitrogen under the condition of supplying in film module 3 via backwashing pump etc. from filtrate tank.
Below the filter method of filter 1 with said structure is described.In filter 1, stoste flows into from the inflow entrance 5a of stoste supply pipe 5, and this stoste is supplied with to the primary side of film module 3 via stoste arm 7.In film module 3; Stoste flows into the through hole 35 that also passes through fixed component 34a in the housing 32 from the inflow entrance 32a of primary side; Flow into fixed component 34a, the stoste between the 34b is under external pressure through hollow-fibre membrane 30, is discharged from as filtrating from the outlet 32b of secondary side.In addition, the concentrate that is not filtered through hollow-fibre membrane 30 is discharged from from concentrate arm 36.The filtrating of discharging from outlet 32b is discharged to filtrating discharge pipe 9 via filtrating arm 11.The concentrate of discharging from concentrate arm 36 is discharged to concentrate discharge pipe 13a, 13b.
Fig. 9 is the sketch map of the existing filter of expression.As shown in Figure 9, existing filter 50 has two stoste supply pipes 51,52, two filtrating discharge pipes 53; 54 and two concentrate discharge pipes 55,56, each film module 60 respectively with stoste supply pipe 51; 52, filtrating discharge pipe 53,54 and concentrate discharge pipe 55,56 connect.This through branch's pipe arrangement to two stoste supply pipes 51; 52 supply with in the structure of stoste; Because the obstruction of film module 60 etc.; Difference in flow appears in the stock solution flow of the stock solution flow of a stoste supply pipe 51 and another root stoste supply pipe 52, the instability of assignment of traffic in two stoste supply pipes 51,52, possibly occur.
To this, in the filter 1 of this embodiment, stoste supply pipe 5 is positioned at the bottom of film module 3 and extends along the direction that a plurality of film modules 3 form a line, and is configured in corresponding to first and second module column 3a, the position between the 3b.In addition, stoste supply pipe 5 is connected through stoste arm 7 with the primary side of film module 3.Like this, from a stoste supply pipe 5 via stoste arm 7 to each film module 3 branch, so make the flow substantially constant of from inflow entrance 5a to end side (closed side) easily, can keep the flow substantially constant of the stoste that provides to film module 3.Therefore, filter 1 can seek to improve the distributivity of flow.
And in this embodiment, filtrating discharge pipe 9 is positioned at the top of film module 3 and extends along the direction that a plurality of film modules 3 form a line, and is configured in corresponding to first and second module column 3a, the position between the 3b.In addition, filtrating discharge pipe 9 is connected through filtrating arm 11 with film module 3.Like this, identical through the formation that makes filtrating discharge pipe 9 with stoste supply pipe 5, can further improve the distributivity of the flow of filter 1.
And in this embodiment, the outlet 9a of the inflow entrance 5a of stoste supply pipe 5 and filtrating discharge pipe 9 is opening in the same direction.Like this; Because the outlet 9a and the concentrate discharge pipe 13a of the inflow entrance 5a of stoste supply pipe 5, filtrating discharge pipe 9, the outlet 14a of the tube connector 14 of 13b is opening in the same direction, therefore; For example under the situation of the configurating filtered device 1 of small space, can seek to improve utilization of space.
And, in filter 1, can reduce pipe arrangement owing to comparing with existing structure, therefore can seek to reduce cost.And,, can also reduce the process number of making filter 1, thereby seek to improve operation property through reducing pipe arrangement.
Then, other embodiments are described.Figure 10 is the front view of the filter of other embodiments, and in filter 1A shown in Figure 10, the structure of concentrate discharge pipe 13A is different with above-mentioned embodiment.Shown in figure 10, filter 1A has a concentrate discharge pipe 13A.Concentrate discharge pipe 13A filtrating discharge pipe 9 below and be configured between the first module column 3a and the second module column 3b.Film module 3 is connected through concentrate arm 36A with concentrate discharge pipe 13A, and this concentrate arm 36A extends to concentrate discharge pipe 13A side straight line from the side of the housing 32 of each film module 3.
Figure 11 is the front view of the filter of other embodiments, and in filter 1B shown in Figure 11, the structure of concentrate discharge pipe 13B is different with above-mentioned embodiment.Shown in figure 11, filter 1B has a concentrate discharge pipe 13B, concentrate discharge pipe 13B filtrating discharge pipe 9 below and be configured between the first module column 3a and the second module column 3b.Film module 3 is connected through concentrate arm 36B with concentrate discharge pipe 13B, and this concentrate arm 36B extends from the side of the housing 32 of each film module 3 to concentrate discharge pipe 13B straight line, and its roughly mid portion to above extend.At this filter 1A, among the 1B, because concentrate discharge pipe 13A, 13B is one, therefore can form easy structure.
In addition, in filter 1A, concentrate arm 36A also can constitute structure shown in Figure 12.Shown in figure 12, the concentrate arm 36a that the film module 3 of one side extends from the diagram top and the relative direction of film module 3 form specified angle and extend, and are connected with concentrate discharge pipe 13B.In addition, the concentrate arm 36b that extends from the film module 3 of the opposite side of diagram below forms specified angle (to the relative direction inclination) with the relative direction of film module 3 and extends, and is connected with concentrate discharge pipe 13B.Be that concentrate arm 36a and concentrate arm 36b can not be connected in concentrate discharge pipe 13B on same straight line, its bearing of trend also can not be identical direction.
The utility model is not limited to above-mentioned embodiment, for example, in the above-described embodiment, constitute filter 1 by a plurality of unit 2a～2c, but the structure of filter 1 is not limited thereto.
And, in the above-described embodiment, illustration the outlet 14a of outlet 9a and tube connector 14 of the inflow entrance 5a of stoste supply pipe 5, filtrating discharge pipe 9 in the structure that is positioned on the short transverse of filter 1 on the roughly same straight line.But inflow entrance 4a, outlet 9a and outlet 14a also can stagger each other on width (Y direction) and dispose.
