The specific embodiment
Below describe embodiment of the present invention in detail based on accompanying drawing.Fig. 1 is the diagrammatic side views of one of expression membrane component embodiment of the present invention, the state before expression is installed in diffusion barrier 11 on the support plate 12.Fig. 2 is the diagrammatic side views of one of embodiment that is illustrated in the film unit 42 that has used this membrane component 1 membrane module 41 of combination diffusion blowning installation.Fig. 3 is the top diagrammatic top view of this film unit 41 of expression.
The upper end of support plate 12 has the infiltration water outlet 17 of nozzle form.On the other hand, laminar diffusion barrier 11 is set, forms the filtered water space (filtration hydroecium) of flowing thus in the inboard of diffusion barrier at the positive and negative of support plate 12.And infiltration water outlet 17 is connected with filtration hydroecium between diffusion barrier 11 and the support plate 12 by intercommunicating pore 18.Filtering and enter the indoor filtered water of filtered water from the outside of diffusion barrier 11 discharges from infiltration water outlet 17 by intercommunicating pore 18.
Through bolt is set on the spacer portion 13 to be inserted through with hole 14.As shown in Figures 2 and 3, through bolt 46 is inserted through with hole 14 fastening a plurality of membrane components 1 by through bolt, the former current road 51 between each membrane component is maintained fixed, thereby can between each membrane component, flow through uniform gas-liquid mixed stream.In addition, because be firmly fastened between the spacer portion of the membrane component of adjacency, so even when fluctuation taking place, also can prevent the wearing and tearing of spacer portion 13 and the breakage of support plate 12 because of the high-speed gas-liquid mixed flow.
Be arranged on the shape that the through bolt of spacer portion 13 is inserted through with hole 14 and be not particularly limited, can determine according to the required fastening force of spacer portion.But, if when forming the positive and negative that connects membrane component as shown in Figure 1 to the hole of the recess shapes of side surface direction opening, then can from the side through bolt 46 be inserted the membrane component of stack, operation becoming easily, so preferably.In addition, the degree of depth of recess shapes is more than the diameter of through bolt 46, through bolt 46 integral body can be accommodated in the hole of recess shapes.The degree of depth of recess shapes is in the face direction of membrane component and is the length on the horizontal direction, and is the length from the ledge of spacer portion to sunk part, shown in the L1 among Fig. 1.
Through bolt is inserted through with the number in hole 14, size etc. also can be determined according to the needed fastening force of spacer portion.As the required fastening force of spacer portion, can enumerate 1kg/cm
2More than (9.807 * 10
4Pa) stress is preferably set simultaneously with the specification of through bolt 46, so that obtain this fastening stress.For example, when using the through bolt 46 of M12～M16 (SUS304 system), preferably on two spacer portion, diameter (circle) is set and is inserted through with hole 14 than the through bolt of the big 0.5～3mm of bolt with the interval of 100～1000mm.
In Fig. 1～3, the width of spacer portion 13 is uniformly on the length direction (vertical direction during use) of membrane component, but also can preferably use the uneven shape of this width.Need to prove that the width of so-called spacer portion shown in L2 among Fig. 1, is meant that through bolt is inserted through with the part beyond the hole 14 in membrane component face direction and be the length on the horizontal direction.
In addition, for example the load that causes at gas-liquid mixed stream is very high, when needing further to improve the power of fastening spacer portion, and the methods such as diameter that can consider to increase the radical of through bolt or increase through bolt, but shortcoming is all arranged under any situation.When increasing the through bolt radical, the problem that exists the assembling of problem that the cost of through bolt increases or film unit 42 to become loaded down with trivial details.In addition, increase the through bolt diameter and when increasing fastening force, because must be corresponding to the width of the increasing diameter large-spacing portion of bolt, so problem that also exists the cost of support plate to raise, perhaps because the increase of the area of the part that contact with the adjacency membrane component, so the problem of each one of even fastening spacer portion occurs being difficult to.
Therefore, in order to address the above problem, also preferred membrane component 1 as shown in Figure 4 is provided with flange part 23 discontinuously in the outside portion of spacer portion 13, through bolt is set in this flange part 23 is inserted through with hole 14.This flange part 23 can carry out one-body molded the manufacturing by utilizing the raw material identical with other parts of spacer portion 13.If be said structure, then can keep fastening force by the through bolt that runs through specified diameter, in addition, owing to can dwindle the area of the spacer portion of contact, so can fastening equably each other each spacer portion.
