Description
Technical field
The utility model relates to a kind of external placed type hollow-fiber membrane bioreactor that is used for sewage disposal.
Background technology
At present, tubular fibre has been widely used in filtration or the purifying treatment to water or liquid.Former water sees through the micropore permeation of hollow-fibre membrane and becomes water purification.In the use, materials such as the colloid in the former water, suspended particulates are constantly concentrated and the hollow-fibre membrane surface, cause efficient to reduce, and therefore, need clean.The hollow fiber film assembly that is used for membrane bioreactor mainly adopts immerseable not have the periostracum assembly, there is the gas-liquid skewness, tubular fibre is easily by the mud adhesion, cleaning operation is loaded down with trivial details, be difficult to clean-in-place, hollow fiber film assembly repair maintenance difficulty, hollow-fibre membrane is easily damaged by foreign matter, reduces thereby make film forming work-ing life.
The utility model content
Technical problem underlying to be solved in the utility model is, overcome the defective that existing technology exists, and provide a kind of new external placed type hollow-fiber membrane bioreactor, it can realize that feed liquid is evenly distributed, the clean-in-place of membrane module, no dead angle can prevent the adhesion between the fiber, system is easy to management and maintenance, and strainability is stable.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of external placed type hollow-fiber membrane bioreactor, the gas-liquid distributor, the shell that comprise hollow fiber bundle, band center Link Port, gas-liquid distributor is positioned at an end of membrane module, hollow fiber bundle places in the gas-liquid distributor, membrane module one end fiber and gas-liquid distributor bonding are also fixed in the enclosure, the other end of membrane module is open, and at the housing upside of this end material liquid outlet is set.
The gas-liquid distributor of band center Link Port is made of radial grid distributor, is furnished with pod apertures on the grid distributor, and there is the center Link Port at the position therebetween.
Shell is connected together by the arc snap ring of fast-assembling by housing, sieve tube and an end end socket and constitutes.
Hollow fiber bundle and gas-liquid distributor are with in resin package sieve Yu tube.
Between housing and sieve tube by the stressed joint of quick-mounting clamp ring lock.
Have gas-liquid mixed feed liquid inlet on the end socket and see through the liquid outlet, end socket has the pipe connecting that inserts gas-liquid distributor center Link Port.
The other end fibrous bundle of membrane module is to seal and dispersive.
The other end fibrous bundle of membrane module is the structure of U type.
Working process is: feed liquid evenly flows into through sparger from end socket central authorities inlet, flows out at material liquid outlet, and the outside surface that sees through liquid process hollow-fibre membrane sees through the hole of film and enters hollow fiber cavity and flows out, and has realized the filtering separation process of feed liquid.
The utility model is evenly distributed feed liquid (comprising liquid and gas), has improved the operation and the cleaning efficiency of film, and membrane module is detachable, can clean-in-place, no dead angle can prevent the adhesion between the fiber, system is easy to management and maintenance, reaches the stable purpose of strainability.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is an overall construction drawing,
