Description
Technical field
It the utility model is related to a kind of percussion flow photocatalysis membrana separator.
Background technology
When membrane separation process handles natural organic wastewater, due to containing a large amount of humic acid in natural organic wastewater, easily make
Into serious fouling membrane and concentration polarization phenomenon, the normal operation of membrane filtration is hindered.To naturally having before membrane filtration or when filtering
Machine waste water carries out photocatalysis treatment, humic acid in waste water is moderately degraded, strengthens its hydrophily, is control fouling membrane and concentration polarization
Change most efficient method；Photocatalysis efficiency is improved, then is that the technology is successfully crucial.Generally it is aerated, is aerated during photocatalysis
On the one hand oxygen is provided, the generation of hydroxyl radical free radical can be promoted, on the other hand, the turbulence caused by liquid internal is aerated, can carry
High mass transfer rate, improve the efficiency of photochemical catalytic oxidation.It is relatively low due to being commonly aerated the less turbulence caused by liquid internal, to passing
The improvement of matter performance is limited, thus constrains the further raising of photocatalysis membrana separative efficiency.
Utility model content
Its purpose of the utility model, which is that, provides a kind of percussion flow photocatalysis membrana separator, can be applied to natural organic
The photocatalysis membrana separating treatment of waste water, the present apparatus are strengthened the absorption of oxygen and the characteristics of material transfer rate using percussion flow, exposed
Gas part impact tube hits aeration and instead of traditional bubble type aerator, enhances the absorption of oxygen, improves liquid
Interior material transfer rate, so as to improve photocatalytic oxidation efficiency, mitigate the fouling membrane in membrane filtration and concentration polarization, there is height
Imitate compact object point.
The technical scheme realized above-mentioned purpose and taken, include the shell of drum-shaped, the bottom of shell is provided with sewage draining exit, outside
Membrane module is provided with shell, the membrane module is arranged on the centre position of drum-shaped shell, and the both sides of the membrane module are symmetrical arranged
Two ultraviolet lamp tubes, are symmetrical arranged two impact tubes below the membrane module, and the side of impact tube is provided with that diameter is identical, the center of circle
Multiple small pipes point-blank are uniformly distributed, the opposite side of impact tube is connected with air inlet pipe, described two impact tubes pair
Put, multiple small pipe faces on two impact tubes are opposed.
Beneficial effect
The utility model has advantages below compared with prior art.
The device replaces common aeration using percussion flow aeration, can not only improve absorption rate, increases molten in liquid
Oxygen content is solved, promotes the generation of hydroxyl radical free radical, and the mass transfer rate in device can be improved, improves the oxygen of hydroxyl radical free radical
Change efficiency.In addition, percussion flow can cause pressure oscillation and vibration in film surface, membrane contaminant is prevented in the deposition of film surface, therefore the dress
Put with it is efficient the advantages of.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present apparatus；
Fig. 2 is the impact tube structural representation in the present apparatus.
Embodiment
The present apparatus includes the shell 1 of drum-shaped, and the bottom of shell 1 is provided with sewage draining exit 6, is provided with membrane module 3 in shell 1, such as
Shown in Fig. 1, Fig. 2, the membrane module 3 is arranged on the centre position of drum-shaped shell 1, and the both sides of the membrane module 3 are symmetrical arranged
Two ultraviolet lamp tubes 2, the lower section of the membrane module 3 are symmetrical arranged two impact tubes 4, the side of impact tube 4 be provided with diameter it is identical,
The center of circle is uniformly distributed multiple small pipes 7 point-blank, and the opposite side of impact tube 4 is connected with air inlet pipe 5, described two to hit
Hit that pipe 4 is opposed, multiple small faces of pipe 7 on two impact tubes 4 are opposed.
Embodiment
As shown in figure 1, the shell 1 of this percussion flow photocatalysis membrana separator is drum-shaped, bottom is provided with sewage draining exit 6,
Centre sets membrane module 3, and the both sides of membrane module 3 are symmetrical arranged two ultraviolet lamp tubes 2, and the lower section of the membrane module 3 is symmetrically set
Two impact tubes 4 are put, impact tube 4 is connected with air inlet pipe 5.
As shown in Fig. 2 the side of impact tube 4 is that diameter is identical, the center of circle is uniformly distributed multiple roundlets point-blank
Pipe 7, opposite side are connected with air inlet pipe 5, and two impact tubes 4 are opposed in percussion flow photocatalysis membrana separator, multiple small pipes
Face.
Its operation principle is as follows：
In percussion flow photocatalysis membrana separator, the opening by pending natural organic wastewater and photochemical catalyst from top
Adding apparatus, two ultraviolet lamp tubes 2 are powered, air enters opposed impact tube 4 from the air inlet pipe 5 on both sides, and air is from shock
Pipe 4 carries out bubbling and hit to promote the absorption of oxygen in a liquid after coming out；In the presence of ultraviolet light and catalyst, absorption
Oxygen and water generation hydroxyl radical free radical, after hydroxyl radical free radical contacts with the pollutant in waste water, occur oxidation reaction, by pollutant
Degraded.After pre-processing certain time to natural organic wastewater photocatalysis, outwards aspirated from membrane module 3, clear water is obtained through fenestra
To the percolate of purification, pollutant is trapped into device.Pressure oscillation, vibration can be produced in the film surface of membrane module 3 by hitting aeration
And air scour, prevent pollutant from being deposited in film surface, so as to control fouling membrane.
