Description
Technical field
The present invention relates to a kind of membrane component, particularly a kind of hollow fibre membrane component, is mainly used in field of water treatment equipment.
Background technology
Hollow-fibre membrane two ends, no matter be external-compression type, take out the mode that negative pressure or inner pressed all adopt two ends all sealing, are namely all fixed on the two ends of shell by existing hollow fibre membrane component with glue.
Such as, publication number is that the utility model patent of CN201470318U just provides a kind of column type hollow fiber membrane modular with step end structure, and comprise pressure-bearing type shell, the two ends, outside of pressure-bearing type shell are provided with termination, and termination connects end cap; The inside of pressure-bearing type shell is provided with hollow-fibre membrane, the both sides of hollow-fibre membrane are respectively equipped with fluid sealant, it is characterized in that, the top of termination has staircase structural model, staircase structural model protrudes from the end face of fluid sealant, forms miniature catch basin between staircase structural model and the end face of fluid sealant.This utility model patent is claimed, the utility model has the advantages that to facilitate to install termination accurately, makes it coordinate closely with bearing shell, can retaining on a small quantity in miniature catch basin, makes testing more intuitively easy.
And for example publication number be utility model patent the utility model of CN20139932 provide a kind of in pressure tube-type demountable hollow fiber film assembly, in this hollow fiber film assembly, there is mounting-positioning holes termination to boundling, inside there is hollow fiber film tube locating hole, hollow fiber film tube inserts in hollow-fibre membrane locating hole respectively, and keeps even axial distribution.Gap in hollow fiber film tube and boundling termination between hollow fiber film tube locating hole, carry out bonding with bonding agent, make film pipe become as a whole with boundling termination, the mounting-positioning holes on boundling termination is used for film pipe and boundling termination, and overall accessory is connected with shell etc.This utility model patent is claimed, this assembly is very convenient when mounting and dismounting, and easily cleans, and be particularly suitable for and the feed liquid that can process containing suspended solid not high to feed liquid pre-processing requirements, and structure is simple, dependable performance, transports light.
But the pillar ultrafiltration membrane elements of above-mentioned two kinds of forms contamination resistance when actual motion is poor, pollutant is easily deposited in film pipe, is difficult to pollutant to discharge, the cleaning and regeneration weak effect of film.Because above-mentioned reason, in order to slow down the pollution of film, extend its service life, the pillar ultrafiltration membrane elements of existing structure could must use in complicated pre-place techniques such as prime configuration precipitation, sand filtrations, adds equipment investment and operating cost.
In addition, in film processing system, the pollution of film is difficult to avoid, and in order to slow down the pollution of membrane component, during actual motion, membrane module will carry out periodicity air purge and backwash frequently.At film in membrane component backwash and air purge process, can produce thermal agitation to film silk, the membrane component fixing for prior art two ends easily causes film silk to rupture.Have again, in the fabrication process, the technique that hollow fiber film thread has stretch orientation to shape usually, be encapsulated in after in two sections of fixing putaminas, hollow fiber film thread has the trend of disorientation, occur also causing the phenomenon that film silk shrinks the fracture of hollow fiber film thread, thus affect the normal use of assembly.
In addition according to the dissection and analysis to membrane component ruuning situation under cross-flow technique of prior art, find that pollutant is all that alluvial is at cross-flow exit end.This just causes one end packing phenomenon of pollutant, even if repeatedly rinse, is also difficult to take away with regard to pollutant.
Summary of the invention
