[details of embodiments of the present invention]
Hereinafter, being illustrated referring to attached drawing to the filtering module and filter device of embodiments of the present invention.
[first embodiment]
< filtering module >
The filtering module 1 of Fig. 1 has: multiple hollow-fibre membranes 2, is stretched and is aligned by (Z-direction) along the vertical direction, and with curtain
Shape arrangement；The upper end of above-mentioned hollow-fibre membrane 2 is fixed in upside holding member 3；And downside holding member 4, among the above
The lower end of empty fiber membrane 2 is fixed.As shown in figure 3, the filtering module 1 is in upside holding member 3 and downside holding member 4
Upside holding member 3 in the internal external pressure for having and passing through the filtered filtering water route 5 for crossing drainage discharge of hollow-fibre membrane 2
Formula or impregnated filtering module.In addition, " external-compression type " is that the periphery surface side of hollow-fibre membrane is instigated to become high pressure and make to be located
The mode that reason liquid is penetrated to the inner peripheral surface side of hollow-fibre membrane.In addition, " impregnated " is the inner peripheral surface side for instigating hollow-fibre membrane
The mode for penetrating liquid to be treated to inner peripheral surface side." impregnated " is also referred to as " aspiration-type ".
As shown in figure 3, filtering water route 5 has: multiple first water collecting part 5a, along the longitudinal direction pair of upside holding member 3
Multiple hollow-fibre membranes 2 are divided, and are connected to respectively for the open end of the multiple hollow-fibre membranes 2 marked off；And second
Water collecting part 5b is connected to multiple first water collecting part 5a, and has the row that drainage was discharged from a side end of upside holding member 3
Export 5c.
For the filtering module 1, upside holding member 3 has in inside will be filtered by hollow-fibre membrane 2
The filtering water route 5 of drainage discharge is crossed, therefore the drainage of crossing for having penetrated multiple hollow-fibre membranes 2 can be made to lead in the filtering water route 5
It crosses and is discharged.For the filtering module 1, filtering water route 5 has: multiple first water collecting part 5a, along upside holding member 3
Longitudinal direction divides multiple hollow-fibre membranes 2, and connects respectively for the open end of the multiple hollow-fibre membranes 2 marked off
It is logical；And the second water collecting part 5b, it is connected to multiple first water collecting part 5a, and have from a side end of upside holding member 3 and be discharged
The outlet 5c of drainage is crossed, therefore can be realized the homogenization of the filtration yield of multiple hollow-fibre membranes 2, improved the production of drainage
Efficiency.In other words, it is believed that in the case where multiple hollow-fibre membranes 2 are directly connected to the second water collecting part 5b, collect with second
The hollow-fibre membrane 2 of the side the outlet 5c connection of water portion 5b is easy to apply the suction pressure of drainage, thus with the second water collecting part 5b
The side outlet 5c connection hollow-fibre membrane 2 filtering quantitative change it is more, on the other hand, with the outlet 5c's of the second water collecting part 5b
The filtration yield of the hollow-fibre membrane 2 of opposite side connection tails off.In contrast, thinking for the filtering module 1, Duo Gezhong
Empty fiber membrane 2 is connected to multiple first water collecting part 5a, therefore is able to suppress multiple doughnuts using above-mentioned suction pressure as cause
The deviation of the filtration yield of film 2, thus, it is possible to improve the filter efficiency of multiple hollow-fibre membranes 2.
(upside holding member)
As shown in Figures 1 and 2, upside holding member 3 is formed as in the horizontal direction of the beam of multiple hollow-fibre membranes 2
Longitudinal direction (X-direction) is as the rodlike of longitudinal direction.It is formed in addition, upside holding member 3 shows greatly rectangular-shape.Upside is protected
Component 3 is held with the upper surface and the lower surface with horizontal direction parallel, is connected with multiple hollow-fibre membranes 2 in the lower surface.On
Side holding member 3 have lower surface be connected with multiple hollow-fibre membranes 2 main body 3a and the longitudinal direction from main body 3a one
Side end is to discharge nozzle 3b outstanding on the outside of longitudinal direction, and the opening shape of discharge nozzle 3b is at outlet 5c.Upside is kept
Part of the component 3 other than the interconnecting part and outlet 5c being connected to multiple hollow-fibre membranes 2 becomes seal shape.On in addition,
Side holding member 3 has a pair of of the recessed bar slot 3c extended along the long side direction in a pair of of side.A pair of of recessed bar slot 3c is formed in upper
Opposite position in the horizontal direction of a pair of of side of side holding member 3.In addition, " rodlike " refers to elongated shape.
The lower limit of longitudinal direction average length as main body 3a, preferably 0.4m, more preferably 0.7m.As main body 3a
Longitudinal direction average length the upper limit, preferably 1.5m, more preferably 1.2m.If the longitudinal direction average length of main body 3a is not
The above-mentioned lower limit of foot is then probably difficult to for the filtering module 1 to be used for large-scale filter device.If the longitudinal direction of main body 3a is averagely long
Degree is more than the above-mentioned upper limit, then probably operability reduces.In contrast, by making the longitudinal direction average length of main body 3a be in upper
It states in range, so as to inhibit the operational reduction of the filtering module 1, and gives full play to based on multiple first water collecting parts
The improvement effect of the filter efficiency of 5a.
Mean breadth (length in the direction vertical with the longitudinal direction in the horizontal direction of main body 3a) as main body 3a
Lower limit, preferably 30mm, more preferably 40mm.The upper limit of mean breadth as main body 3a, preferably 100mm, more preferably
For 70mm.If the above-mentioned lower limit of mean breadth deficiency of main body 3a, is probably unable to fully improve the filtration yield of the filtering module 1.
If the mean breadth of main body 3a is more than the above-mentioned upper limit, probably the operability of the filtering module 1 is reduced, and is probably difficult to clean
Positioned at the hollow-fibre membrane of width direction (Y-direction) central portion.
(filtering water route)
Filtering water route 5 is formed in the inside of the main body 3a of upside holding member 3.Filtering water route 5 has multiple first to catchment
A portion 5a and second water collecting part 5b.In addition, the second water collecting part 5b is located at the upside of multiple first water collecting part 5a.In other words,
Multiple first water collecting part 5a are connected in lower section with multiple hollow-fibre membranes 2, and in the side being connected to multiple hollow-fibre membranes 2
Opposite side be connected to the second water collecting part 5b.
The first water collecting part of < >
Multiple first water collecting part 5a are respectively formed as using the longitudinal direction of upside holding member 3 as longitudinal direction substantially
Rectangular-shape.Multiple first water collecting part 5a are in the lower section of the second water collecting part 5b throughout the both ends of the longitudinal direction of the second water collecting part 5b
And it is arranged.It is preferred that the average length of the longitudinal direction of multiple first water collecting part 5a is equal.Additionally, it is preferred that multiple first water collecting part 5a
Mean breadth it is equal with the mean breadth of the second water collecting part 5b.
The lower limit of the average length of longitudinal direction as the first water collecting part 5a, preferably 50mm, more preferably 80mm.Make
For the upper limit of the average length of the longitudinal direction of the first water collecting part 5a, preferably 400mm, more preferably 200mm.If above-mentioned average
The above-mentioned lower limit of curtailment, then the longitudinal direction length of the first water collecting part 5a unnecessarily becomes smaller, as a result, first catchments
The number of portion 5a increases and probably the filtration yield of multiple hollow-fibre membranes 2 between these first water collecting parts 5a generates deviation.If
Above-mentioned average length is more than the above-mentioned upper limit, then I'm afraid the filter efficiency of multiple hollow-fibre membranes 2 in each first water collecting part 5a
Generate deviation.
The lower limit of number as the first water collecting part 5a in upside holding member 3, preferably 2, more preferably 3.As
The upper limit of the number of the first water collecting part 5a in upside holding member 3, preferably 8, more preferably 7.If in above-mentioned number deficiency
Lower limit is stated, then the longitudinal direction length of each first water collecting part 5a becomes too long, probably in multiple in each first water collecting part 5a
The filtration yield of empty fiber membrane 2 generates deviation.If above-mentioned number is more than the above-mentioned upper limit, probably between multiple first water collecting part 5a
The filtration yield of multiple hollow-fibre membranes 2 generates deviation.
In addition, in the filtering module 1, the preferably average length of the longitudinal direction of the first water collecting part 5a and the first water collecting part 5a
Number within the above range.The filtering module 1 is by making the average length and first of the longitudinal direction of the first water collecting part 5a
The number of water collecting part 5a within the above range, so as to promote the multiple hollow-fibre membranes being connected to each first water collecting part 5a
The homogenization of 2 filtration yield, and sufficiently improve the whole filtration yield of the filtering module 1.
The lower limit of radical as the hollow-fibre membrane 2 being connected to each first water collecting part 5a, preferably 150, more preferably
200.As the upper limit of above-mentioned radical, preferably 3000, more preferably 2500.If the insufficient above-mentioned lower limit of above-mentioned radical, each the
The filtration yield of one water collecting part 5a is insufficient, and then is probably unable to fully improve the filtration yield of the filtering module 1.If above-mentioned radical is super
The above-mentioned upper limit is crossed, then probably the filtration yield of multiple hollow-fibre membranes 2 in each first water collecting part 5a is easy to produce deviation.
In addition, the lower limit of total quantity as the multiple hollow-fibre membranes 2 being connected to upside holding member 3, preferably
1000, more preferably 1500.As the upper limit of above-mentioned total quantity, preferably 6000, more preferably 5000, further preferably
4500.If the above-mentioned above-mentioned lower limit of total lazy weight, probably it is unable to fully improve the filtration yield of the filtering module 1.If above-mentioned
Total quantity is more than the above-mentioned upper limit, then probably the filtration yield of multiple hollow-fibre membranes 2 is easy to produce deviation.
First water collecting part 5a preferably has intercommunicating pore 5d in the opposite side for the side being connected to multiple hollow-fibre membranes 2.The
One water collecting part 5a and the second water collecting part 5b are connected to by intercommunicating pore 5d.As the intercommunicating pore for being formed in each first water collecting part 5a
The upper limit of the number of 5d, preferably 3, more preferably 2, further preferably 1.In addition, being formed in a first water collecting part 5a
In the case where multiple intercommunicating pore 5d, preferably these intercommunicating pores 5d to form at equal intervals.And filtering module 1 particularly preferably each the
One water collecting part 5a is formed in the long side of the first water collecting part 5a with the intercommunicating pore 5d of intercommunicating pore a 5d, multiple first water collecting part 5a
Central portion on direction.The filtering module 1 being capable of the multiple doughnuts easy to accomplish that be connected to each first water collecting part 5a as a result,
The homogenization of the filtration yield of film 2, the homogenization of the filtration yield for the multiple hollow-fibre membranes 2 for promoting the filtering module 1 whole.This
Outside, intercommunicating pore 5d is preferably formed in the central portion of the width direction of the first water collecting part 5a.
It as the shape of intercommunicating pore 5d, is not particularly limited, circle, ellipse, triangle, polygon etc. can be enumerated.Wherein,
As the conveniently of circular shape of intercommunicating pore 5d.In addition, the diameter as intercommunicating pore 5d, as long as being able to suppress multiple doughnuts
The deviation of filtration yield in film 2 and the drainage of crossing for being directed into the first water collecting part 5a be discharged to the second water collecting part 5b, then not spy
It does not limit, such as 1mm or more and 50mm or less can be become.In addition, " diameter of intercommunicating pore 5d ", which refers to, to be had and intercommunicating pore 5d
Area equation area positive diameter of a circle.
As shown in figure 4, the intercommunicating pore 5d of multiple first water collecting part 5a also can have identical diameter.The filtering module 1
In the case where the intercommunicating pore 5d of the first water collecting part 5a multiple like this has the same diameter, based on as caused by intercommunicating pore 5d
The pressure loss can be realized the homogenization from each first water collecting part 5a to the second water collecting part 5b flowing water amount.As shown in figure 5,
The intercommunicating pore 5d of multiple first water collecting part 5a also can be located remotely from the intercommunicating pore 5d of the position of outlet 5c, and then diameter is got over
Greatly.The filtering module 1 is possible to more be proximate to the intercommunicating pore 5d of outlet 5c, then easier by the mistake being discharged from outlet 5c
The influence of the suction pressure of drainage.The face it is therefore contemplated that the intercommunicating pore 5d for passing through the position for being located remotely from outlet 5c is then open
Product is bigger, is able to suppress using the suction pressure as the deviation of the filtration yield of cause.And, it is believed that the filtering module 1 is for example, by increasing
The number etc. for adding the intercommunicating pore 5d of the first water collecting part 5a of the position for being located remotely from outlet 5c, can also make the conjunction of intercommunicating pore 5d
