Description
Technical field
This utility model belongs to sewage treatment area, particularly relates to a kind of ejector.
Background technology
In sewage disposal, water resource recycling field, MBR reactor, also known as membrane bioreactor, is a kind of by membrance separation
The new type water treatment technology that unit combines with biological processing unit.The membrane structure type used is mainly Flat Membrane and doughnut
Film, can be divided into hyperfiltration technique by membrane aperture.This device mainly utilizes membrane module that the membrane material of unlike material makes by aperture
Retaining in the reactor more than the material of fenestra, thus obtain a kind of technique of the water outlet more cleaned, this technique instead of biography
Secondary sedimentation tank in system activated sludge process, not only has more preferable solid-liquid separation effect, also has the pollutant in waste water more
Strong removal ability, is widely used in the process of sanitary sewage and industrial wastewater.
During in prior art, MBR film is usually used in aerobic reaction pond, this is because containing solids such as more mud in waste water
Impurity, easily produces blocking to MBR membrane module, and typically requires in aerobic reaction pond and carry out Air Exposure, and aeration process again can
Enough MBR film is well washed away, thus avoid the blocking of MBR membrane module.And anaerobic reation pool is confined space, no
Air Exposure being carried out, if using MBR film to carry out solid-liquid separation, being easy to the blocking that MBR film occurs.
Utility model content
The purpose of this utility model is that the MBR film overcoming prior art to exist holds susceptible to plugging defect, it is provided that a kind of jet
Device.
This utility model solves its technical problem and be the technical scheme is that a kind of ejector, including the first water inlet pipe
With the second water inlet pipe, the outlet of described first water inlet pipe is in the taper shunk, and described second water inlet pipe includes that be sequentially connected with enters
Mouth section and outlet section, described inducer is in the taper shunk, and the outlet of the first described water inlet pipe is corresponding with described inducer,
And described inducer is in communication with the outside, described first water inlet pipe and inducer junction form negative pressuren zone, described outlet section top
Being provided with nozzle, described nozzle is flat.
As preferably, for ease of the connection between the second water inlet pipe and the first water inlet pipe, described second water inlet pipe extenal fixation
Connect and have the fixing muscle for it being connected with the first water inlet pipe.
Further, being provided with flange bottom described fixing muscle, described fixing muscle is by described flange and the first water inlet
Pipe connects.
Further, described outlet section includes trunnion and the anemostat being sequentially connected with, described trunnion and described inducer
Connecting, described nozzle is arranged on described anemostat.
As preferably, for ease of being connected with other pipelines by ejector, bottom the first described water inlet pipe, it is provided with connection
Pipe.
Beneficial effect: utilize the outlet of the first water inlet pipe and the pyramidal structure of the inducer of the second water inlet pipe in the application,
Make to be formed negative pressuren zone in both junctions, thus can in negative pressuren zone surrounding sucks biochemistry pool while being passed through new sewage
Treated waste water, both mixing, reach good mixed effect, reduce the COD of newly entering sewage, reduce the load to strain
Impact, improves treatment effect；It addition, use flat nozzle so that the hydraulic shock power sprayed by ejector is big, and washes away
Area is big, it is possible to effectively wash away MBR membrane module, it is to avoid MBR film blocks.

Detailed description of the invention
Embodiment
As illustrated in fig. 1 and 2, a kind of ejector, including the first water inlet pipe 1 and the second water inlet pipe, described first water inlet pipe 1
Exporting in the taper shunk, described second water inlet pipe includes inducer 2 and the outlet section being sequentially connected with, and described inducer 2 is in receipts
The taper of contracting, the outlet of the first described water inlet pipe 1 is corresponding with described inducer 2, and described inducer 2 is in communication with the outside,
Described first water inlet pipe 1 and inducer 2 junction form negative pressuren zone 9, and described outlet section includes the trunnion 3 being sequentially connected with and expands
Dissipating pipe 4, described trunnion 3 is connected with described inducer 2, and described anemostat 4 is provided with nozzle 5, and described nozzle 5 is in flat；
Described second water inlet pipe extenal fixation connects the fixing muscle 6 for it being connected with the first water inlet pipe 1, and specifically, described consolidates
Determining to be provided with bottom muscle 6 flange 7, described fixing muscle 6 is connected with the first water inlet pipe 1 by described flange 7.
For ease of being connected with other pipelines by above-mentioned ejector, bottom the first described water inlet pipe 1, it is provided with connecting tube 8.
Operation principle is as follows, and the application ejector is arranged on MBR membrane module bottom, the sewage newly entered or the sewage of circulation
Enter successively through the first water inlet pipe 1 and the second water inlet pipe through connecting tube 8, in entering of the first water inlet pipe 1 outlet and the second water inlet pipe
Under mouth section 2 pyramidal structure effect, forming negative pressuren zone 9 in both junctions, the sewage that in biochemistry pool, footpath has processed is at suction function
Under be inhaled into inducer 2 by negative pressuren zone 9 surrounding and mix with newly entering waste water, thus reach the purpose of mixing, and right
Forming the effect of stirring in biochemistry pool, mixed sewage is sprayed by nozzle 5 through outlet section, thus rushes MBR membrane module
Brush, owing to nozzle 5 is in flat, its impulsive force is big, and it is big to wash away area, and scouring effect is good.
Should be appreciated that specific embodiment described above is only used for explaining this utility model, be not used to limit this reality
With novel.The obvious change extended out by spirit of the present utility model or variation are still in protection of the present utility model
Among scope.
