Abstract
The utility model discloses a kind of MBR film case, comprise the skeleton of three-dimensional arrangement, be fixed on intraskeletal at least one diaphragm, be arranged on some aeration tubes bottom skeleton, this skeleton four side is provided with shrouding.The utility model MBR film case is transformed the film case skeleton in traditional really meaning, in the side of skeleton, shrouding is set, closed cavity is formed by the diaphragm of shrouding to inside of four sides, realize film case truly, this closed film case can limit the aeration tube bubble trend of bottom, make it according to the longitudinal flow of film case, such bubble can all act on membrane surface and wash away, improve the working efficiency of aeration tube, simultaneously, more bubble is conducive to the fermentable in membrane surface residue in diaphragm, make residue process more thorough.
Description
Technical field
The utility model relates to water technology, especially a kind of MBR film case.
Background technology
Polyvinylidene difluoride (PVDF) is a kind of macromolecular material of excellent property, has good chemical stability, thermostability and physical strength.Therefore utilize polyvinylidene difluoride (PVDF) to make hollow-fibre membrane, this Pvdf Microporous Hollow Fiber Membrane is widely applied at membrane bioreactor (MBR).
Work because this tunica fibrosa is immersed in sewage, therefore the casing fixed and aeration tube is needed to wash away the residue of membrane surface, but the casing of fixing diaphragm is not containment housing truly, and be the skeleton of casing, aeration tube is arranged on the bottom of skeleton, wash away the diaphragm in skeleton, fact proved, this open skeleton film case efficiency is very low, the bubble of aeration tube blowout all can not act on diaphragm toward directly over, bubble ascent direction is unrestricted, and part bubble can scatter toward side.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of closed MBR film case.
The technical solution adopted in the utility model is:
A kind of MBR film case, comprise the skeleton of three-dimensional arrangement, be fixed on intraskeletal at least one diaphragm, be arranged on some aeration tubes bottom skeleton, at least one side of this skeleton is provided with shrouding.
Preferably, this side, skeleton front, rear, left and right four is provided with shrouding.
Preferably, this shrouding first half is provided with through hole.
Wherein, this shrouding all seals or the side of part sealing framework.
Further, described MBR film case also comprise be communicated with respectively the upper and lower two ends of diaphragm on to catchment end, next part water end (W.E.), the two root framves up and down of described skeleton one side be respectively the square tube that catchments, under to catchment square tube, on catchment square tube, under the square tube that catchments there is some water inlet pipes, the end that catchments on described is directly communicated with the water inlet pipe of the square tube that above catchments, next part water end (W.E.) directly with under the catchment water inlet pipe of square tube be communicated with, above catchment square tube with under catchment between square tube and be communicated with by a supporting tube.
The square tube that catchments on described is provided with a rising pipe.
The beneficial effects of the utility model:
The utility model MBR film case is transformed the film case skeleton in traditional really meaning, in the side of skeleton, shrouding is set, closed cavity is formed by the diaphragm of shrouding to inside of four sides, realize film case truly, this closed film case can limit the aeration tube bubble trend of bottom, make it according to the longitudinal flow of film case, such bubble can all act on membrane surface and wash away, improve the working efficiency of aeration tube, simultaneously, more bubble is conducive to the fermentable in membrane surface residue in diaphragm, make residue process more thorough.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
Fig. 1 is the structural representation of the utility model MBR film case.
Embodiment
As shown in Figure 1, for a kind of MBR film case of the present utility model, comprise the skeleton 1 of three-dimensional arrangement, be fixed at least one diaphragm 2 in skeleton 1, be arranged on the some aeration tubes 3 bottom skeleton 1, be communicated with respectively diaphragm about 2 two ends on to catchment end 6, next part water end (W.E.) 7, the two root framves up and down of described skeleton 1 one side are respectively the square tube 8 that catchments, under to catchment square tube 9, on to catchment square tube 8, under the square tube 9 that catchments there is some water inlet pipes 10, the end 6 that catchments on described is directly communicated with the water inlet pipe 10 of the square tube 8 that above catchments, next part water end (W.E.) 7 directly with under the catchment water inlet pipe 10 of square tube 9 be communicated with, on catchment square tube 8 with under catchment between square tube 9 and be communicated with that next part water end (W.E.) 7 is led to the square tube 8 that catchments by a supporting tube 11, on the square tube 8 that catchments be provided with a rising pipe 12.
As mentioned above, on the end 6 that catchments directly be communicated with the water inlet pipe 10 of the square tube 8 that above catchments, next part water end (W.E.) 7 directly with under the catchment water inlet pipe 10 of square tube 9 be communicated with, the end that herein catchments optimizes the complicated pipeline of tradition greatly with the direct mode of connection (grafting or be threaded) between square tube, make water outlet more efficient, and save materials;
Main innovate point of the present utility model is: this at least one side of skeleton 1 is provided with shrouding 4, and preferably, this side, skeleton 1 front, rear, left and right four is provided with shrouding 4, forms the closed cavity surrounding diaphragm 2 in the vertical.
Preferably, this shrouding 4 first half is provided with through hole 5, certain open treated is done on this through hole 5 forms cavity basis at shrouding 4, is convenient to aeration tube 3 and is got rid of from this through hole 5 in time by the residue on diaphragm 2 surface.
Wherein, the side of the whole sealing of this shrouding 4 or part sealing framework 1, shrouding 4 selected in the accompanying drawing of the present embodiment is part sealing, at the first half opening of skeleton 1 side; Here it should be noted that, part sealing also comprises other forms of sealing, as grating stripe board, and concentric ring, or if diagram is only at left and right side reinforcing shrouding 4, the change of these conventional design is all within protection domain of the present utility model.
The utility model MBR film case is transformed the film case skeleton 1 in traditional really meaning, in the side of skeleton 1, shrouding 4 is set, closed cavity is formed by the diaphragm 2 of shrouding 4 to inside of four sides, realize film case truly, this closed film case can limit the aeration tube 3 bubble trend of bottom, make it according to the longitudinal flow of film case, such bubble all can act on diaphragm 2 surface and wash away, improve the working efficiency of aeration tube 3, simultaneously, more bubble is conducive to the fermentable in diaphragm 2 surface residue in diaphragm 2, make residue process more thorough.
The foregoing is only preferred embodiments of the present utility model, the utility model is not limited to above-mentioned embodiment, as long as the technical scheme realizing the utility model object with basic same approach all belongs within protection domain of the present utility model.
