Abstract

The invention discloses a process method and process equipment for cleaning a tubular ultrafiltration membrane by dissolved gas water. The process method comprises a technology of promoting sewage to separate from a linear ultrafiltration membrane, and the invention also provides equipment for cleaning the tubular ultrafiltration membrane by dissolved gas water. The equipment for cleaning the tubular ultrafiltration membrane by dissolved gas water consists of a cleaning pipe (1) provided with radial small holes (2), sewage inlets (3), a linear ultrafiltration membrane (4), an ultrafiltration pipe body (5), concentrated water outlets (6) and conditioning water outlets (7). Dissolved gas water is introduced into the cleaning pipe (1) and is discharged from the radial small holes (2) of the cleaning pipe, and the sewage is separated from the linear ultrafiltration membrane by utilizing the shock generated by bursting of bubbles, so that the effect of the cleaning the linear ultrafiltration membrane (4) is achieved, the cleaned sewage is discharged from the concentrated water outlets (6) along with water. The process method and the process equipment are used for solving the technical problem that the tubular ultrafiltration membrane cannot be cleaned thoroughly.

Description

A kind of process of dissolved air water cleaning tubular ultra-filtration membrane and equipment
Technical field
The present invention relates to process and equipment, the particularly cleaning technique of tubular ultra-filtration membrane of a kind of dissolved air water cleaning tubular ultra-filtration membrane.
Background technology
Tubular ultra-filtration membrane is most widely used in water treatment field.It uses pressure differential to promote membrane separating process, and the solution in raw material, by through membrane component, now just reaches the object of concentrating and separating and solution purification.At present, the cleaning of tubular ultra-filtration membrane remains a large technical barrier, and traditional method for washing cleaning performance is poor, there is cleaning dead angle.
Summary of the invention
The object of the invention is to provide a kind of dissolved air water to clean the process of tubular ultra-filtration membrane for the problems referred to above, the use of this process can eliminate the problem that there is cleaning dead angle in cleaning tubular ultra-filtration membrane process well, dissolved air water is passed in cleaning tubular ultra-filtration membrane process, a large amount of free bubble that dissolved air water decompression produces, be attached to wire ultrafiltration membrane surface, the powerful impact that free water follicular rupture produces instantaneously, make dirt and wire Ultra filtration membrane, play the effect of cleaning wire milipore filter, the dirt after cleaning is discharged with water.
With the process equipment of dissolved air water cleaning tubular ultra-filtration membrane by being provided with the scavenge pipe (1) of scavenge pipe radial hole (2), sewage inlet (3), wire milipore filter (4), milipore filter body (5), dense water out (6), process water out (7) form.
The pipeline that described scavenge pipe (1) is closed for one end, coaxially be placed in milipore filter body (5), the part that scavenge pipe (1) is positioned at ultrafiltration membrane pipe body (5) is provided with the scavenge pipe radial hole (2) be evenly arranged, wire milipore filter (4) is filled with between milipore filter body (5) inwall and scavenge pipe (1) outer wall, dissolved air water is passed in scavenge pipe (1), discharged by scavenge pipe radial hole (2), the free bubble that dissolved air water decompression produces, wire ultrafiltration membrane surface can be attached to, the powerful impact that free water follicular rupture produces instantaneously, make dirt and wire Ultra filtration membrane, play the effect of cleaning wire milipore filter (4), dirt after cleaning and water are discharged from dense water out (6).
Compared with prior art, the invention has the beneficial effects as follows: the cleaning performance of (1) tubular ultra-filtration membrane is good, can realize good Penetration ration for a long time; (2) solve milipore filter cleaning and there is the difficult problem at dead angle, improve milipore filter service life.
