Description
Technical field
The utility model belongs to environmental protection water technology and membrane separation technique field, particularly a kind of external pressure weeping willow formula hollow-fibre membrane or capillary-pipe film filter that has comprised quick-fried device of air.This kind film filter is applicable to membrane bioreactor (MBR), intensified membrane bioreaction device (MEBR) and membrane filtration.
Technical background
Common decomposition pressure formula of hollow-fibre membrane or capillary-pipe film or submerged membrane filter in the known technology.Wherein the submerged membrane filter is normally used for the higher liquid of impurity screening.The submerged membrane filter generally by in the liquid around the film from bottom to top waterfall gas lower solid impurity in the liquid in the deposition on film surface with to the pollution on film surface.It is the biochemical reaction liquid that filters in the biochemical reactor that is used for sewage disposal that submerged membrane filters a kind of special applications of setting up; This technology that biochemical reactor and membrane filtration module are combined is called as membrane bioreactor.Chinese patent (application number 200610002387X) has disclosed the intensified membrane bioreaction device (MEBR) that biofilm reactor and membrane filtration are combined in addition.The submerged membrane filter has curtain formula and pillar in the known technology.Chinese patent application (application number 200720155208.6) has disclosed a kind of weeping willow formula film filter of vertical placement, wherein hollow-fibre membrane or capillary-pipe film top are drawn sap cavity with the top and are cast in, hollow-fibre membrane or capillary-pipe film inner chamber and top are drawn sap cavity and top and are drawn the sap cavity liquid sucking tube and be communicated with, and hollow-fibre membrane silk or capillary-pipe film lower end seal respectively and scatter relatively.Apply negative pressure by draw the sap cavity liquid sucking tube to the top during use, liquid being filtered sees through the hollow-fibre membrane silk under the atmospheric pressure effect or the capillary membranous wall enters inner chamber, enters liquid sucking tube through drawing sap cavity then.This film filter makes that at film silk bottom waterfall gas air scour film surface effect is better, and the solid impurity that the film surface comes off can fall more freely and leave the film surface.One of submerged membrane filter common trait is doughnut or capillary-pipe film filter to be immersed in be filtered in the liquid.This mode makes that the cleaning of film is comparatively difficult.
The pressure type membrane filtering device that is used for membrane bioreactor in the known technology mainly is the inner pressed film filter.This inner pressed film filter often need form higher flow rate of liquid to avoid the pollution of pollutant to the film surface on the film surface.Film surface high liquid flow velocity is realized by liquid circulation pump usually, has caused relatively large ability loss.
United States Patent (USP) (application number 20040035779A1) has disclosed a kind of pasture and water formula membrane module, it is characterized in that every hollow-fibre membrane silk or capillary-pipe film one end fixed to one another, hollow-fibre membrane silk or capillary-pipe film inner chamber with draw sap cavity inner chamber and bottom and draw the sap cavity liquid sucking tube and be communicated with, the hollow-fibre membrane silk or the capillary-pipe film other end seal respectively and scatter relatively, hollow-fibre membrane silk or capillary-pipe film end fixed to one another scatters end upwards relatively down.This film filter be filtered the solid suspension that dams when falling easily in hollow-fibre membrane silk or capillary-pipe film bottom bearing deposition, bring film from the bottom pollution problems gradually upwards.In addition when the quick-fried gas flushing of needs, gas is can only be from the next door of hollow-fibre membrane or capillary-pipe film quick-fried goes into, and influences the scouring effect of gas.Chinese patent (ZL03230296.7) has been cancelled quick-fried device of air on the kit form basis of class formula, increased pressure vessel.This filter exists solid suspension to deposit at hollow-fibre membrane silk or capillary-pipe film bottom bearing easily when falling equally, bring film from the bottom pollution problems gradually upwards, owing to lack effective quick-fried device of air, cause when using gas to wash away, to exist and wash away the dead angle simultaneously.
Summary of the invention
The utility model to solve in the prior art in the immersion weeping willow film filter hollow-fibre membrane or capillary-pipe film surface liquid flow velocity low, be easy to generate the dirt technical problem that the external-compression type film filter exists gas to wash away the dead angle in the technical problem of film surface deposition and known technology, a kind of weeping willow formula external pressure hollow-fibre membrane or capillary-pipe film filter that has comprised quick-fried device of air is provided.
Aerating gas external pressure willow type membrane filter of the present utility model comprises many hollow-fibre membranes or capillary-pipe film, and two are drawn sap cavity, a shell and a waterfall device of air.Wherein hollow-fibre membrane or capillary-pipe film top are drawn sap cavity with the top and are cast in, hollow-fibre membrane or capillary-pipe film inner chamber and top are drawn sap cavity inner chamber and top and are drawn the sap cavity liquid trap and be communicated with, the sealing and scattering relatively respectively of hollow-fibre membrane or capillary-pipe film upper end.Hollow-fibre membrane or capillary-pipe film place tells enclosure.Outer casing bottom draws sap cavity with the bottom and is connected, the bottom draw sap cavity be provided with feed tube to and admission line.The quick-fried device of air that admission line draws in the sap cavity bottom being located at is communicated with.The waterfall device of air is upwards continuous or interruption waterfall gas in filter bottom, and cover top portion is provided with gas liquid outlet.Liquid being filtered sees through hollow-fibre membrane or capillary membranous wall under pressure and enters the top and draw in the sap cavity, enters liquid trap then in drawing sap cavity.Because hollow-fibre membrane or capillary-pipe film bottom can freely swing, be located at the bubble that quick-fried device of air is produced under these hollow-fibre membranes or the capillary-pipe film bottom and can more effectively wash away the film surface.
Technical characterictic of the present utility model is a branch of upper end is cast in together, doughnut that the lower end seals respectively or capillary-pipe film place all to be had up and down in the pressure casing that draws sap cavity, be provided with quick-fried device of air in outer casing bottom draws sap cavity, continuously or be interrupted quick-fried gas, shell upper is provided with the gas-liquid flow outlet.
Technical characterictic of the present utility model is that also described quick-fried device of air can be aerating pipe or aerate head.
