Abstract
The utility model discloses a kind of MBR membrane modules aerators, and including aeration manifold and several aeration branch pipes connected with aeration manifold, emptying pneumatic operated valve is equipped in aeration branch pipe end.The utility model can be blocked to avoid membrane module lower end aeration tube.
Description
Technical field
The utility model is related to a kind of MBR membrane modules aerators.
Background technology
MBR membrane treatment process at present（Membrane Bio-Reactor,MBR）It is widely transported in sewage treatment industry
With.In order to which speed is blocked up in the dirt for reducing film, film group is aerated, by being aerated the shake to film wire, by what is adhered in film wire
Cenobium is shaken off.But aeration tube impregnates in biochemical sludge for a long time, membrane module lower end aeration tube can be gradually dirty by biochemical sludge
It is stifled, cause film group aeration uneven, cause the local dirty stifled of film group, serious commercial is caused to influence.
Utility model content
The purpose of this utility model is that：It proposes a kind of MBR membrane modules aerator, can be aerated to avoid membrane module lower end
Pipe is blocked.
The purpose of this utility model is realized by following technical proposals：
A kind of MBR membrane modules aerator, several aeration branch pipes connected including aeration manifold and with being aerated manifold,
Emptying pneumatic operated valve is equipped in aeration branch pipe end.
In this patent, pneumatic operated valve is vented by opening, the gas in aerated conduit is vented, sewage is located at by aeration tube
The aeration head of film device lower end enters in aerated conduit, is then then turned on being aerated, and gas pushes sewage outflow aeration road.The flowing of water
Play an important role of significantly to rinse to aeration tube, avoid aeration tube gradually dirty stifled by sludge.
Alternatively, it is aerated manifold to connect with aeration branch pipe by two-way pipeline in parallel, is set respectively on the two-way pipeline
It is equipped with superposition purging wind pneumatic operated valve and often exposes and purge Pneumatic butterfly valve.In the program, moved by empty pneumatic operated valve with being superimposed purging general mood
The purging to aeration tube is realized in valve and the often cooperation of exposure purging Pneumatic butterfly valve.
As further selection, control device is further included, control device purges respectively with being superimposed purging wind pneumatic operated valve, often exposing
Pneumatic butterfly valve is connected with emptying pneumatic operated valve, and control superposition purging wind pneumatic operated valve often exposes purging Pneumatic butterfly valve and is vented pneumatic operated valve
Opening and closing.In the program, the purging to aeration tube or even the cleaning of automation are realized by the control of control device.
The foregoing main scheme of the utility model and its each further selection scheme can be freely combined to form multiple schemes,
The scheme that can be used and be claimed for the utility model；And the utility model,（Each non conflicting selection）Between selection and
It can also be freely combined between other selections.Those skilled in the art are after the present invention program is understood according to the prior art and public affairs
Know that common sense can be understood there are many combination, be the claimed technical solution of the utility model, do not do exhaustion herein.
The beneficial effects of the utility model：Aeration tube impregnates in biochemical sludge for a long time, and aeration tube can be gradually by biochemical dirty
Dirt is blocked up, and causes film group aeration uneven, causes the local dirty stifled of film group, serious commercial is caused to influence.Therefore, this patent will be aerated
Pipeline is transformed, and by increasing emptying pneumatic operated valve in aeration branch pipe end, changes aeration mode, aeration tube is avoided to be blocked.
Description of the drawings
Fig. 1 is the plane arrangement structure schematic diagram of the single film group of sewage disposal described in the utility model embodiment；
Fig. 2 is one group of film group A-A sections schematic diagram described in the utility model embodiment；
In figure, 1, superposition purging wind pneumatic operated valve；2nd, purging Pneumatic butterfly valve is often exposed；3rd, it is vented pneumatic operated valve；4th, film device；5th, film
Bay wall body；6th, aeration head；7th, it is aerated manifold；8th, aeration branch pipe；9th, aeration tube.
Specific embodiment
The utility model is further described with reference to specific embodiments and the drawings.
With reference to shown in figure 1,2, a kind of MBR membrane modules aerator is connected including aeration manifold 7 and with aeration manifold 7
Several aeration branch pipes 8,8 end of aeration branch pipe be equipped with emptying pneumatic operated valve 3.Be aerated manifold 7 by two-way pipeline in parallel with
Aeration branch pipe 8 connects, and superposition purging wind pneumatic operated valve 1 is respectively arranged on the two-way pipeline and often exposure purges Pneumatic butterfly valve 2.Aeration
Branch pipe 8 corresponds to each film device 4 equipped with aeration tube 9, and aeration tube 9 stretches into has aeration 6, aeration in film device lower end under liquid level
First 6 pairs of film devices 4 are aerated.Pneumatic butterfly valve 2 is purged by closing to be superimposed purging wind pneumatic operated valve 1 and often expose, unlatching is dropped a hint
Dynamic valve 3, the gas in aerated conduit is vented, and the aeration head 6 that sewage is located at film device lower end by aeration tube 9 enters aeration tube
In, it then opens again and often exposes the purging unlatching aeration of Pneumatic butterfly valve 2, gas pushes sewage outflow aeration tube 9.The flowing of water is to aeration tube
9 play an important role of significantly to rinse, and avoid aeration tube 9 gradually dirty stifled by sludge.
Further, control device is further included, control device is respectively with being superimposed purging wind pneumatic operated valve 1, often exposing purging pneumatically
Butterfly valve 2 and emptying pneumatic operated valve 3 connect, and control superposition purging wind pneumatic operated valve 1 often exposes purging Pneumatic butterfly valve 2 and is vented pneumatic operated valve 3
Opening and closing.Purging to aeration tube or even the purging of automation are realized by the control of control device, control device can be used existing
Various control devices, such as microcontroller etc..Preferably control action is：Often exposure purging Pneumatic butterfly valve 2 and superposition is first closed to blow
Swing flap pneumatic operated valve 1 opens simultaneously emptying pneumatic operated valve 3,5（It is adjustable）After second, emptying pneumatic operated valve 3 is closed, opens simultaneously and often exposes purging
Pneumatic butterfly valve 2,10（It is adjustable）Second, it is repeated 3（It is adjustable）It is secondary.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
