Abstract
The utility model discloses a gas-guide aerator of a curtain hollow fiber membrane module, which comprises a plurality of aerated conduits on which a plurality of aerated hatches are arranged. One end of each aerated conduit is connected with a gas distributing box on which an admitting port is arranged, and the other end is connected with a gas-guide tube. A solenoid pilot actuated valve is fixed at a vent in the gas-guide tube. The gas-guide aerator of the curtain hollow fiber membrane module has the beneficial effects that the mud at the aerated hatchs can be cleaned, the aerated affection caused by the mud is reduced and the best aerated effect is ensured.
Description
Technical field
The utility model relates to the aerating apparatus in the membrane bioreactor, relates in particular to double purging, the aeration that is used for curtain formula hollow-fibre membrane and cleans aerating apparatus in one.
Background technology
Hollow-fibre membrane since its to have resistance to pressure good, need not supporter, advantage such as unit volume film surface-area is big, and flux is big is widely used in the membrane bioreactor.Aeration is important link in the membrane bioreactor, and it provides necessary oxygen for existence biological in the reactor.In the existing curtain formula hollow fiber membrane reactor, aeration tube be placed on usually membrane module below, bubble from bottom to top arrives the surface of mixed solution, in this process, the oxygen in the bubble is understood some and is dissolved in mixed solution, reaches the effect of oxygenation; Simultaneously, the bubble that aeration tube discharges can directly purge on the film surface, and the liquid turbulent flow that causes together with bubble can play shake effect, decelerating membrane pollution to the film surface.But after operation for some time, the aeration opening on the aeration tube can inevitably be adhered to some mud, and these mud have certain inhibition to aeration, also can the blocking aeration mouth when serious.Do not clean the device of aeration opening in the general aeration tube.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, provides a kind of and can automatically, periodically clean aeration opening, with the curtain formula hollow fiber film assembly air guide aerating apparatus of the optimal effectiveness that guarantees aeration.
The technical scheme that its technical problem that solves the utility model adopts is:
Curtain formula hollow fiber film assembly air guide aerating apparatus, it comprises many aeration tubes that have a plurality of aeration opening on it, one end of described aeration tube is connected with the gas distribution box that has inlet mouth on it, and the other end is connected with airway, and described airway is positioned at exhaust ports a magnetic valve is installed.
The beneficial effects of the utility model are, can clean the mud at aeration opening place, reduce the influence of mud accumulation to aeration, guarantee the best effects of aeration.
Description of drawings
Fig. 1 is the shaft side figure of curtain formula hollow fiber film assembly air guide aerating apparatus of the present utility model.
Fig. 2 is the top plan view of curtain formula hollow fiber film assembly air guide aerating apparatus of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Curtain formula hollow fiber film assembly air guide aerating apparatus as shown in drawings, it comprises the many aeration tubes 3 that have a plurality of aeration opening 4 on it, one end of described aeration tube 3 is connected with the gas distribution box 2 that has inlet mouth 1 on it, the other end is connected with airway 5, and described airway 5 is positioned at exhaust ports a magnetic valve 6 is installed.
In Fig. 1, in use, aerating apparatus and hollow fiber film assembly are arranged in the reactor shell, and aerating apparatus is arranged in the below of hollow fiber film assembly 7.Among Fig. 1 Fig. 2, inlet mouth 1 is on gas distribution box 2, and gas distribution box 2 connects some aeration tubes 3, aeration opening 4 is arranged on the aeration tube 3, and these aeration tubes 3 are linked on the airway 5 simultaneously, and airway 5 reaches whole reactor housing outside, be connected with atmosphere, magnetic valve 6 controls are equipped with at the external interface place.
At aeration phase, magnetic valve 6 cuts out, and airway 5 is not communicated with the external world, and gas enters into aeration tube 3, by aeration opening 4 place's aerations.
At wash phase, magnetic valve 6 is opened, airway 5 is in communication with the outside, will be by the gas that inlet mouth 1 enters not at aeration opening 4 place's aerations, be discharged in the outside air but enter airway 5, at this moment gas has higher flow velocity in aeration tube 3, because its venturi action, the gas pressure energy reduces, and the liquid in the reactor can enter in the aeration tube 3 by the aeration opening on the aeration tube 34; Magnet valve 6 is closed, airway 5 is not communicated with the external world again, and at this moment, the gas that enters from inlet mouth 1 can eject the liquid the aeration tube 3 by aeration opening 4, enter aeration phase.In cleaning process, the liquid flow influent stream in the reactor goes out twice by aeration opening 4, the mud at aeration opening 4 places can be taken away, and plays the effect of cleaning aeration opening 4.The time of cleaning is for once a day, each 6～8 minutes.
