Membrane bioreactor (MBR) be gradually rise in recent years one kind in advanced treatment of wastewater technology, because it is with work
The many merits such as skill process is short, high treating effect, occupied area is few, microorganism concn is high are in quickly in practical projects
Developing stage.Certainly, MBR is while with many merits, it may have certain disadvantage: 1. 2. fouling membrane than is comparatively fast invested into
This is higher.Especially membrane pollution problem has become and limits a universal urgent problem to be solved of its Rapid Popularization.
Fouling membrane refers to film during the filtration process, and physics occurs for the particle, colloidal particle or solute transportation and film in water
It adsorbed in film surface or fenestra caused by chemical action or mechanism, deposit and membrane aperture is caused the work such as to become smaller or block
With making film generate the phenomenon that permeation flux and stalling characteristic change.For fouling membrane, there is no occur for the structure of film itself
Variation can make the performance recovery of film or part be restored to original state as long as through cleaning appropriate.Therefore, for film
Membrane reactor is cleaned in pollution problem, and the service life for extending membrane module just becomes the hot spot that membrane reactor is studied and asks
Topic.
At present there are mainly two types of the cleaning ways of membrane bioreactor: on-line cleaning and offline cleaning.It is either online clear
It washes or offline cleaning, MBR module is all not normally functioning, the water yield decline of whole system.
A kind of self-cleaning MBR flat sheet membrane module and its cleaning were once disclosed in Chinese patent application 201310314883.9
Method, the membrane module are to be fixed on plate membrane in special frame to be made, and add charger to carry out film in frame
Gas flushing.The self-cleaning MBR flat sheet membrane module and its cleaning method realize MBR membrane module self-cleaning in the process of running, pole
The earth improves its resistant to pollution ability, but still remains following problems:
1, for chemical using orientation spray, clean range is limited, and medicament waste is serious；
2, it is purged using gas, power consumption is high, energy waste；
3, gas purging deposits the low defect of intensity, and general effect is poor.
Utility model content
Good, easy to use, operating cost saving plate membrane that the purpose of this utility model is to provide a kind of cleaning effects
On-line cleaning device.
In order to solve the above technical problems, the utility model uses following technical scheme:
A kind of plate membrane on-line cleaning device, which is characterized in that including connected drug-feeding tube and chemical feed pipe, drug-feeding tube goes out
Mouthful place is equipped with atomizer, and cannula cleaning is housed by bearing holder (housing, cover) outside chemical feed pipe, and chemical feed pipe is equipped with duct, on cannula cleaning
Equipped with aperture, opening direction is along cannula cleaning tube wall tangential direction.
The drug-feeding tube is formed by connecting by transverse tube and vertical tube, and the side of vertical tube is equipped with track, the outer wall of vertical tube be equipped with
The sliding block of track adaptation.
The outer diameter of the cannula cleaning is less than the spacing of plate membrane, is slightly less than 1-2cm, the length and plate membrane of cannula cleaning
It is of same size.
The drug-feeding tube is equipped with booster pump, and drug-feeding tube is flexible duct.
The diameter in duct is 0.1-1mm on the chemical feed pipe.
The atomizer is refraction type atomizer.
The cannula cleaning is the steel-plastics composite pipe that internal layer is lined with polytetrafluoroethylene ethylene layer.
The utility model has the beneficial effects that:
1) cleaning effect is good.Chemical feed pipe is arranged in by bearing mode in the cannula cleaning of the utility model on-line cleaning device
Outside, thus by cannula cleaning spray Application of spray chemical cleaning technology for evaporating agent sprayed through tangential aperture when cannula cleaning can be made to rotate,
Chemical feed pipe and cannula cleaning can be run up and down along track simultaneously, thus can be flat after so that cannula cleaning is placed in plate membrane inside
The operation up and down of plate film inside, the chemical sprayed due to rotation is comprehensive to plate membrane progress, cleans without dead angle, cleans model
It encloses more extensively, effect is more preferable.
2) easy to use, it is stable.On-line cleaning is carried out to plate membrane using the on-line cleaning device of the utility model,
Cleaning process can cover the Life cycle of plate film assembly.Using utility model device in the cleaning process to plate membrane
In, it does not need that plate membrane is stopped intaking, does not influence the production water and treatment effeciency of MBR processing system.
3) operating cost is low.Cleaning agent sprays on-line cleaning device described in the utility model by atomization in use
The atomization process of head makes cleaning agent enter chemical feed pipe and cannula cleaning in spray pattern, and final spray pattern ejection is cleaned,
The usage amount of cleaning agent can be reduced under the premise of reaching same cleaning effect, save reagent cost.
