Description
Technical field
The invention belongs to plate membrane cleaning technique field, and in particular to a kind of plate membrane on-line cleaning device and its cleaning side
Method.
Background technology
Membrane bioreactor（MBR）Be gradually rise in recent years it is a kind of in advanced treatment of wastewater technology, because it is with work
The many merits such as skill flow is short, high treating effect, floor space is few, microorganism concn is high, are in quick in Practical Project
Developing stage.Certainly, MBR is while with many merits, it may have it is certain the shortcomings that：2. 1. fouling membrane than is comparatively fast invested into
This is higher.Especially membrane pollution problem, has become a urgent problem to be solved for limiting the popularization of its Rapid Popularization.
Fouling membrane refers to film in filter process, and physics occurs for the particulate, colloidal particle or solute transportation and film in water
Adsorbed caused by chemical action or mechanism in film surface or fenestra, deposit and cause membrane aperture to diminish or blocks etc. work
With the phenomenon for making film generation permeation flux change with stalling characteristic.For fouling membrane, the structure of film in itself does not occur
Change, as long as can just make the performance recovery of film or part return to original state by appropriate cleaning.Therefore, for film
Membrane reactor is cleaned in pollution problem, extend the service life of membrane module just become membrane reactor research hot spot ask
Topic.
The cleaning way of membrane bioreactor mainly has two kinds at present：On-line cleaning and offline cleaning.It is either online clear
Wash or offline cleaning, MBR module are all not normally functioning, the water yield of whole system declines.
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 that plate membrane is fixed 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 modules self-cleaning in the process of running, pole
The earth improves its resistant to pollution ability, but still remains problems with：
1st, chemical is sprayed using orientation, and clean range is limited, and medicament wastes serious；
2nd, purged using gas, power consumption is high, energy waste；
3rd, gas purging deposits the defects of intensity is low, and general effect is poor.
The content of the invention
It is an object of the invention to provide a kind of good, easy to use, operating cost saving the plate membrane of cleaning performance is online
Cleaning device and its cleaning method.
To solve above technical problem, the present invention uses following technical scheme：
A kind of plate membrane on-line cleaning device, it is characterised in that including connected drug-feeding tube and chemical feed pipe, the exit of drug-feeding tube
Equipped with atomizer, cannula cleaning is equipped with by bearing holder (housing, cover) outside chemical feed pipe, chemical feed pipe is equipped with duct, and cannula cleaning is equipped with
Perforate, opening direction are along cannula cleaning tube wall tangential direction.
The drug-feeding tube is formed by connecting You Transverse pipes and vertical tube, and the side of vertical tube is equipped with track, the outer wall of vertical tube equipped with
The sliding block of track adaptation.
The outside 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
Be of same size.
The drug-feeding tube is equipped with booster pump, and drug-feeding tube is flexible duct.
A diameter of 0.1-1mm in duct on the chemical feed pipe.
The atomizer is refraction type atomizer.
The cannula cleaning is lined with the steel-plastics composite pipe of polytetrafluoroethylene ethylene layer for internal layer.
The method cleaned using plate membrane on-line cleaning device to plate membrane, cleaning method step are as follows：1）, will be clear
Casing is washed to be placed in inside plate membrane；2）, the import of drug-feeding tube is connected with equipped with the dosing tank of cleaning agent, cleaning agent is through booster pump
Entering atomizer after pressurization to be atomized, the cleaning agent after atomization enters chemical feed pipe and enters cannula cleaning by the duct of chemical feed pipe,
Sprayed by the perforate on cannula cleaning, rotate cannula cleaning, the medicament of ejection cleans plate membrane；3）, cleaning
During, control slide block is moved up and down along track（It is 10-30cm/min to move up and down speed）, full side is carried out to plate membrane inside
Position cleaning.
The pressure of atomizer is 0.2MPa, flow 50L/h, controls the pressure and flow of atomizer, is to make
Cleaning agent is sprayed with suitable state, cannula cleaning rotating speed caused by avoiding hypertonia, flow excessive it is too fast and to plate membrane
Damage, also avoid not caused enough the cleaning performance of cleaning pressure of cleaning agent caused by pressure is too low, flow is too small poor.
It is 10-30cm/min to control operating rate control of the cannula cleaning inside plate membrane, this is because speed is too high
When, cleaning is difficult to totally thoroughly, and when speed is too low, cleaning efficiency is low and wastes cleaning agent,
Drug-feeding tube is flexible duct, its material is polyesters.
Cannula cleaning is steel-plastics composite pipe, its internal layer is lined with polytetrafluoroethylene ethylene layer.
The beneficial effects of the present invention are：
1）Cleaning performance is good.The cannula cleaning of on-line cleaning device of the present invention is arranged on outside chemical feed pipe by bearing mode, because
This can rotate cannula cleaning when being sprayed by the Application of spray chemical cleaning technology for evaporating agent that cannula cleaning sprays through tangential perforate, while dosing
Pipe and cannula cleaning can be run up and down along track, so that cannula cleaning can be inside plate membrane after being placed in plate membrane inside
Operation up and down, since the chemical that rotation sprays is comprehensive to plate membrane progress, is cleaned without dead angle, clean range is wider,
Effect is more preferable.
2）It is easy to use, it is stable.On-line cleaning device using the present invention carries out plate membrane on-line cleaning, cleaning
Process can cover the Life cycle of plate film assembly.Using apparatus of the present invention in the cleaning process to plate membrane, it is not necessary to
Plate membrane is stopped intaking, does not influence the production water and treatment effeciency of MBR processing systems.
3）Operating cost is low.Cleaning agent passes through atomizer to on-line cleaning device of the present invention in use
Atomization process, makes cleaning agent enter chemical feed pipe and cannula cleaning in spray pattern, and final spray pattern, which sprays, is cleaned, can be
The usage amount of cleaning agent is reduced on the premise of reaching same cleaning performance, saves reagent cost.
