The specific embodiment
Specify the embodiment that is connected structure and has the film separation unit that this connections constructs that hollow fiber film assembly of the present invention and media set intersection pipe and medium inject at least a collector of collector according to accompanying drawing.
In Fig. 1～Fig. 5; Reference numeral 1 is for having the immersion filtration device of hollow fiber film assembly 2; This hollow fiber film assembly 2 have from be connected with the liquid that impregnated in not shown treatment trough with upright state the membrane module lid 3c that is connected of the open end of a plurality of hollow-fibre membranes on the pipe joint 3 of hollow fiber film assembly 2 attract and discharge the structure of the treatment fluid that has carried out the Separation of Solid and Liquid gained, be used for the liquid in this treatment trough of isolated by filtration.
In being connected in the structure of the pipe joint 3 that connects hollow fiber film assembly 2 and resin system or metal system media set intersection pipe 4; The pipe joint 3 of hollow fiber film assembly 2 be set on the position of staggering with this pipe joint 3 relative above-mentioned media set intersection pipe 4 shaft core position 3a, 4a each other; The pipe joint 3 of hollow fiber film assembly 2 is connected by flexible hose 5 with media set intersection pipe 4, and the leading section 6 of media set intersection pipe 4 is inclined to the angle that can connect with the bending radius more than the minimum bending radius of flexible hose 5.
No matter be to attract to filter or pressure filtration, flexible hose 5 all can adopt resin system or the metal flexible hose of strengthening coil that is tied with, and for example, can use the flexible hose about external diameter 34mm, internal diameter 25mm, minimum bending radius 105mm.The axle center tilt angle theta of the leading section 6 of media set intersection pipe 4 is preferably set to respect to vertical direction to tilt to the inside about 20 degree～30 degree.When media set intersection pipe 4 was made up of ABS resin (propylene cyanogen, butadiene, cinnamic copolymer resins) moulding article material, the flexible hose 5 preferred non-PVC of employing (polyvinyl chloride) were resin.
The leading section 6 of the inclination of media set intersection pipe 4 can be arranged on respect to the tube body of this media set intersection pipe on the tube body of this matter set collector with rotating freely.Media set intersection pipe 4 can suchly shown in Fig. 5 (a) be made up of the branch construct that is connected with the pipe joint 3 of a plurality of hollow fiber film assemblies 2, also can suchly shown in Fig. 5 (b) be made up of the ring that is connected with the pipe joint 3 of a plurality of hollow fiber film assemblies 2.
Through constituting media set intersection pipe 4, can make from attraction load, the filtering traffic of a plurality of hollow fiber film assemblies 2 even with branch construct, ring structure.In addition, equally spaced arrange thick and fast, can reduce the installation footprint area, can increase the filtration treatment amount through making hollow fiber film assembly 2.
Shown in Fig. 4 (a), media set intersection pipe 4 is provided with outer race section 7a in a side of the line part of the medium concetrated pipe 7 of T font, inserts the 7b of portion in opposite side is provided with, and outer race section 7a can be nested in this with respect to the periphery of inserting the 7b of portion in this with rotating freely and insert on the 7b of portion.So, just can freely adjust the angle of inclination, axle center of leading section 6.Available bonding agent is bonding between outer race section 7a and the interior slotting 7b of portion, through connect a plurality of medium concetrated pipes 7 just the ring structure shown in (b) of the branch construct shown in (a) of available Fig. 5, Fig. 5 constitute media set intersection pipe 4.
In addition, another kind of media set intersection pipe 4 is to constitute like this.Shown in Fig. 4 (b), (c), at the medium concetrated pipe urceolus 9 of the nested T font of periphery of medium set tube core pipe 8.Substantial middle portion at medium set tube core pipe 8 is formed with the slit 8a that cuts in the scope about the periphery half cycle of this medium set tube core pipe 8, thus be located at the stream 9a that thickly can rotate freely the substantial middle portion of the nested medium concetrated pipe urceolus 9 in ground and be connected by O-ring seals 10 liquid.
When assembling medium set tube core pipe 8 and medium concetrated pipe urceolus 9; At first; Plain washer 11 is set on the medium set tube core pipe 8 and itself and flange part 8b on the end of being located at this medium set tube core pipe 8 are connected; And O-ring seals 10 is set on this medium set tube core pipe 8 and embeds in its slot part; After being set to medium concetrated pipe urceolus 9 on this medium set tube core pipe 8, again another plain washer 11 and urceolus fixed component 12 are set on the medium set tube core pipe 8, and make the side end overlaid and the butt of they and medium concetrated pipe urceolus 9; The threaded portion 8c that urceolus hold-down nut 13 is threaded over the other end that is formed at medium set tube core pipe 8 goes up and screws, thereby medium concetrated pipe urceolus 9 can be installed on the medium set tube core pipe 8 with rotating freely.In this embodiment, the rotatable scope of medium concetrated pipe urceolus 9 is set at 0 degree～180 degree.
The both ends of medium set tube core pipe 8 are embedded into the both end sides of medium concetrated pipe coupling member 14 and connect.In addition, on the stream 9a of the substantial middle portion that is located at medium concetrated pipe urceolus 9, chimeric successively binding has pipeline tube connector joint adapter 15 and pipeline tube connector joint 16, has constituted the leading section 6 of media set intersection pipe 4.
Adopt said structure; Because the leading section 6 of media set intersection pipe 4 is inclined to the angle that can connect with the bending radius more than the minimum bending radius of flexible hose 5; Therefore; Even the pipe joint of hollow fiber film assembly 23 be set on the position of staggering with this pipe joint 3 relative media set intersection pipe 4 shaft core position 3a, 4a each other, also can be easily and connect both sides reliably, and can make by what flexible hose 5 carried out and be connected to become the shortest connection.In addition, also can reduce the pallet height of hollow fiber film assembly 2, can also make the unit frame densification of supporting hollow fiber film assembly 2, thereby in treatment trough, sling unit frame or handle easily when the unit frame put into treatment trough etc.
In addition, shown in figure 10, in the past connection structure is compared with the structure that is connected of the present invention, through the free space that adopts connection structure of the present invention to represent with hatching in the generation of pipe joint 3 tops.This be because, leading section 6 shaft core position each other of pipe joint of hollow fiber film assembly 23 and media set intersection pipe 4 is provided with staggering, therefore, has guaranteed the horizontal direction separating distance Z between two axle center.Therefore, when in soaking into film device, diffuser portion being overhauled, can utilize this free space that hollow fiber film assembly 2 is mentioned top and be easy to maintenance.
In addition; Because the leading section 6 of the inclination of media set intersection pipe 4 can be arranged on respect to the subject freedom of this media set intersection pipe 4 on the main body of this media set intersection pipe 4 rotatably; Therefore; Can freely adjust the axle center tilt angle theta of the leading section 6 of media set intersection pipe 4 according to pipe joint of hollow fiber film assembly 23 and media set intersection pipe 4 each other shaft core position 3a, the stagger degree of 4a relative with this pipe joint 3.
Shown in figure 12, in the present invention, can be that the leading section of media set intersection pipe tilts, also can be to be connected in the pipe joint that membrane module covers to tilt, also can be their both sides tilt.
In addition, owing to use the branch construct or the ring structure that are connected with the pipe joint 3 of a plurality of hollow fiber film assemblies 2 to constitute media set intersection pipe 4, therefore, can closely accommodate a plurality of hollow fiber film assemblies 2.The example of (a) of Fig. 5 and the example of (b) representing branch construct respectively and ring structure.
At this moment, shown in figure 11 in order closely to accommodate, the direction that media set intersection pipe 4 and pipe joint shaft core position each other stagger need be the direction that the interval between the adjacent hollow fiber film assembly is narrowed down.That is, in Figure 11, need satisfy L ' >=L.
In (a) of Fig. 6, show with the central axis of the pipe joint 3 of fixing hollow fiber film assembly 2, be shaft core position 3a and media set intersection pipe 4 central axis, be the pipe arrangement connected mode of shaft core position 4a when being configured on the same straight line.In this case, in the time will using flexible hose 5 tube connector joints 3,, these flexible hose 5 deflections are to a certain degree connected for this flexible hose 5 is inserted on the pipe joint 3 with media set intersection pipe 4.Therefore, the length of this flexible hose 5 needs the so long surplus of deflection.In addition, this moment, the bend that produces because of deflection was 3 places, made this flexible hose 5 crooked and when connecting, and produced reaction force and was difficult to connect in bend branch.Therefore, compare with other pipe arrangement connected modes shown in (b)～(d) of Fig. 6, the reaction force that results from this sweep is bigger.In addition, when connecting, on hollow fiber film assembly 2 and media set intersection pipe 4, bending stress can be produced, this media set intersection pipe 4 distortion or damaged maybe be caused.In order to eliminate this misgivings, need to strengthen this media set intersection pipe thick and heavyly.In addition, when flexible hose 5 during, also there is the problem that is prone to produce crooked folding line for resin system flexible pipe.
In (b) of Fig. 6; Show the pipe joint 3 that makes fixing hollow fiber film assembly 2 central axis, be shaft core position 3a; With the central axis of media set intersection pipe 4, be that shaft core position 4a staggers, thereby guaranteed the pipe arrangement connected mode of situation of the separating distance Z of horizontal direction.The total length of flexible hose 5 has increased the size quantity of separating distance Z; But, therefore, compare with the pipe arrangement connected mode shown in (a) of Fig. 6 because this flexible hose 5 can obtain mild bending radius; The reaction force that results from the flexible hose 5 is less, connects flexible hose 5 easily.
But, in the method for Fig. 6 (b), because bend is two places; Therefore; Not only can not make the length of this flexible hose 5 the shortest, and on the streamline of the fluid of bend pipe internal circulation, can produce vortex, the pressure loss is risen.
In (c) of Fig. 6; Show the pipe joint 3 that makes fixing hollow fiber film assembly 2 central axis, be shaft core position 3a; With the central axis of media set intersection pipe 4, be that shaft core position 4a is consistent, and the pipe arrangement connected mode that the leading section 6 of media set intersection pipe 4 is tilted.At this moment, connect flexible hose 5 easily, but under the situation of the axle center tilt angle theta of the leading section 6 of media set intersection pipe 4, the reaction force that results from the flexible hose 5 is bigger, the total length of this flexible hose 5 has also increased the amount of replication part.In addition, compare with the (a) and (b) of Fig. 6, other pipe arrangement connected modes shown in (d), in the pipe arrangement connected mode shown in (c) of Fig. 6, the length of flexible hose 5 is the longest.
In (d) of Fig. 6 of one of embodiment of the present invention; Show the pipe joint 3 that makes fixing hollow fiber film assembly 2 central axis, be shaft core position 3a; With the central axis of media set intersection pipe 4, be that shaft core position 4a staggers; Guaranteed the separating distance of horizontal direction, and made the pipe arrangement connected mode of leading section 6 inclinations of media set intersection pipe 4.
Such shown in Fig. 6 (d), make the axle center tilt angle theta of the leading section 6 of media set intersection pipe 4 be inclined to suitable angle, just can connect, therefore, can make the bend of this flexible hose 5 be merely 1 place with the minimum bending radius of flexible hose 5.So, this flexible hose 5 just can connect sleekly, and therefore, the strain of this flexible hose 5 is less, is difficult for producing folding line.And, can make the length of flexible hose 5 the shortest, because the pipe joint 3 of hollow fiber film assembly 2 and the separation spacing H of the short transverse between the media set intersection pipe 4 are shortened, therefore can reduce the height of immersion filtration device 1, and can realize densification.In addition, compare, can reduce the pressure loss that produces because of the pipe friction resistance in the pipe arrangement of bent portion with Fig. 6 (b).
In addition, in mode shown in (d) of Fig. 6, when connecting this flexible hose 5,, can connect the pipe joint 3 of hollow fiber film assembly 2 and the leading section 6 of media set intersection pipe 4 with less power through utilizing the elastic force of this flexible hose 5.
In the present invention, the state that the leading section 6 of so-called media set intersection pipe 4 is inclined to the angle that can connect with the bending radius more than the minimum bending radius of flexible hose 5 is meant, can regulate so as follows.For example; When increasing the length of flexible hose 5; Can be through increasing the tilt angle theta of leading section 6, perhaps increase the pipe joint 3 of hollow fiber film assembly 2 central axis, be shaft core position 3a and media set intersection pipe 4 central axis, be that the separating distance Z of the horizontal direction between the shaft core position 4a regulates.
Then; With Fig. 7 the pipe joint 3 of the hollow fiber film assembly 2 of pipe arrangement connected mode shown in Fig. 6 (b), Fig. 6 (d) and the vertical direction separation spacing H between the media set intersection pipe 4 are compared, and the setting of the axle center tilt angle theta of the leading section 6 of explanation media set intersection pipe 4.As shown in Figure 7; Under the state of the horizontal direction separating distance Z between the shaft core position 3a of the pipe joint 3 of shaft core position 4a that has guaranteed media set intersection pipe 4 and hollow fiber film assembly 2; Be used for connecting axle center tilt angle theta drawing-off water horizontal line a on the 3b of the connector top of the pipe joint 3 of hollow fiber film assembly 2 of leading section 6 of the media set intersection pipe 4 of flexible hose 5 with minimum bending radius; Making the starting point of the circular arc that flexible hose 5 draws out is the connector top 3b of the pipe joint 3 of hollow fiber film assembly 2, sets the minimum bending radius R of this flexible hose 5.
The central axis of the leading section 6 of media set intersection pipe 4, and shaft core position 6a on draw horizontal line b through connector top 6b; Can draw the connector top 6b on the shaft core position 6a of leading section 6 of central point O and media set intersection pipe 4 of the minimum bending radius R through flexible hose 5; And the straight line c vertical with this shaft core position 6a asks this straight line c and above-mentioned horizontal line a angulation θ.That is, this angle θ is the axle center tilt angle theta of the leading section 6 of media set intersection pipe 4.Therefore the axle center tilt angle theta equates because horizontal line a, b is parallel but corresponding angles.
At this; The separating distance of the horizontal direction between the shaft core position 3a of the pipe joint 3 of shaft core position 4a that establishes media set intersection pipe 4 and hollow fiber film assembly 2 is Z; If the separation spacing of the vertical direction between the pipe joint 3 of hollow fiber film assembly 2 and the media set intersection pipe 4 is H; If the vertical direction separation spacing H between the pipe joint 3 of hollow fiber film assembly 2 and the media set intersection pipe 4 is that the difference of this H size the most in short-term is Δ H; If the minimum bending radius of flexible hose 5 is R, the central angle of establishing flexible hose 5 formed circular arcs is θ, and the length (length of flexible hose 5) of establishing flexible hose 5 formed circular arcs is L; If the length of the coupling part at flexible hose 5 both ends is LC, then the length of flexible hose 5 can use L=∏ * R * (θ/180)+2 * LC to represent.
In addition; In the above-described embodiment; An example when being applied to shown in Fig. 8 (a) such dipping membranous type filter that makes the filtered fluid decompression type in hollow fiber film assembly 2 impregnated in dipping tank 17 with the state of erectting the liquid is illustrated; But also can be applicable to shown in Fig. 8 (b) such hollow fiber film assembly 2 to be contained in the closed container 18; Stoste is sent in pressurization in this closed container 18; Or the container type filter that reduces pressure and attract filtered fluid and filter; In addition, also can be applicable to have shown in Fig. 9 (a) in such hollow fiber film assembly 2 during being contained in urceolus housing 19 from the inboard interior die mould membrane module structure that filters stoste of hollow-fibre membrane, and as Fig. 9 (b) shown in such the structure of the External Pressure Type membrane module that filters stoste from the hollow-fibre membrane outside, pressurization send into stoste or the various filters of the method for the attraction filtered fluid that reduces pressure in.In addition, in Fig. 8, Reference numeral 20 is a skirt portion, and Reference numeral 21 is a diffuser.
Figure 13 is when applying the present invention in the compression type assembly, uses an example of the method for attachment of flexible hose.
In addition; In the above-described embodiment; The structure that situation was suitable for to media set intersection pipe 4 is connected on a plurality of hollow fiber film assemblies 2 is illustrated; Replacing this media set intersection pipe 4 medium is injected collector and be connected under the situation on a plurality of hollow fiber film assemblies 2, also can adopt identical structure.At this moment, with the above, can the leading section that medium injects the inclination of collector be arranged to and can rotate freely with respect to the tube body that this medium injects collector.
