The air outlet communication apparatus body of blower fan, and blown in device body, device body build-in cavities are provided with open and close door, ceramics
Diaphragm plummer passes through open and close door in-out apparatus body, and positioned at the top of air outlet.
When the present apparatus occurs decaying or cannot still recovering after on-line cleaning for membrane flux when line is runed, by pottery
The drying and dewatering of porcelain diaphragm and diaphragm is burned, can effectively remove the pollutant of membrane removal surface attachment, realize ceramic membrane under offline mode
The thorough regeneration of component recovers, and improve the contamination resistance of plate membrane bioreactor, it is to avoid clear in general soda acid
The structural damage and damage easily occurred under washing method, and solve ceramic membrane chronicity is dirty stifled cannot Chemical cleaning
Thoroughly situation.
Further preferred scheme is that described device body interior also sets and circulating ventilation pipe, the air-out of circulating ventilation pipe
The air inlet of mouth connecting fan, circulation airduct with the lingering remnants of past customs of absorption plant body, and can be followed with the blower fan formation outside device body
Ring air channel, can to carry out high temperature constant temperature to ceramic diaphragm degerming with significantly more efficient；
Further preferred scheme is that the hot blast heating cooking stove further comprises stable-pressure device, self-checking device, combustion fan,
Stable-pressure device controls combustion chamber operational by self-checking device；
Further preferred scheme is that the outer connected control system of the regenerating unit, control system controls hot blast heating cooking stove and wind
Machine is heated and air-supply；
Further preferred scheme is that instrument board is set on described device body, the signal output part connection control system of instrument board
System；
Above-mentioned control system completes Automated condtrol by PLC system control；
Further preferred scheme is that described device body is provided with more than one exhaust outlet, and exhaust is opened after end-of-job
Mouthful
The beneficial effects of the present invention are：
（1）The present apparatus changes the traditional approach decontaminated by soda acid alternative method cleaning ceramic diaphragm, by the way of heating, can
Effectively to remove the pollutant of ceramic diaphragm, conventional sludge adhesion membrane surface is solved, it is impossible to solve by cleaning way
Block the difficulty in duct.
（2）The present apparatus removes the pollutant of diaphragm by physical means, can reduce such as Chemical cleaning, easily causes
The damage of diaphragm ceramic structure, and thus may cause scrapping for diaphragm.
（3）By the application of the present apparatus, it is possible to reduce the general chemical reagent consumed using Chemical cleaning diaphragm, use
It is convenient and easy, be conducive to popularization and application.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is the structural representation of hot blast heating cooking stove of the invention.
Specific embodiment
As shown in Figure 1 and Figure 2, a kind of regenerated offline device of ceramic membrane, including device body 1, hot blast heating cooking stove 6, blower fan
7 and ceramic diaphragm plummer 3；The air inlet of the air outlet connecting fan 7 of the hot blast heating cooking stove 6, the air outlet connection of blower fan 7
Device body 1, and blown in device body 1, the build-in cavities of device body 1 are provided with circulating ventilation pipe 2, device sheet in cavity
Body 1 is externally provided with the exhaust outlet 5 of open and close door 8 and more than 1, the air inlet of the air outlet connecting fan 7 of circulating ventilation pipe 2, pottery
Porcelain diaphragm plummer 3 is additionally provided with instrument by the in-out apparatus body 1 of open and close door 8 on the top of air outlet, device body 1
Dial plate 4, hot blast heating cooking stove 6 and blower fan 7 are all connected with control system, and control system is focused on by PLC is programmable；Described hot blast
Burner 6-1 is provided with the air outlet of heating cooking stove 6, stable-pressure device 6-3, self-checking device, combustion fan, voltage stabilizing dress is further comprises
Put and control combustion chamber 6-2 to work by self-checking device, also through PLC system control；
The course of work of the present apparatus is：Divide following 3 stages：
First stage：Intensification drying stage
90 DEG C, and constant 1 hour or so are progressively warming up to after igniting in hot blast heating cooking stove 6, heat is delivered to ceramics by hot blast
Membrane surface so that the hygroscopic water of surface and inside is evaporated and surface temperature maintains stabilization, is slowly completed moisture evaporation, this process
In, it is impossible to rapidly heat up, prevent water vapour rapid evaporation, cause structural damage.
Second stage：At the uniform velocity heat up and the constant temperature stage
Transmitted by hot blast after the completion of evaporating the surface of ceramic membrane and internal moisture.Development is at the uniform velocity warming up to 200 DEG C, and permanent
Temperature 2 hours or so, treats that partial contamination thing volatilizees；400 DEG C, and constant temperature 1 hour or so are at the uniform velocity warming up to again；Finally about 600
DEG C, constant temperature 1 hour or so.After constant temperature several times works, the pollutant of diaphragm is volatilized substantially and burn clean.
Phase III：The cooling and drying stage
With the carrying out of heat transfer, when membrane surface with it is internal there is no moisture and pollutant after, unnecessary heat can be by
Its surface is delivered to inside by heat transfer, diaphragm is internally formed thermograde, to ensure state of the diaphragm by the rapidly temperature difference
And deform and damage.After constant temperature terminates, cause that the inside and outside of diaphragm under less thermograde, is released by cooling slowly
Thermal discharge, until normal temperature range, completes whole operation process.Such as occur a small amount of pollutant it is serious dirty stifled and it is incomplete
The phenomenon of removing, with During Repeated Heating, and can lengthen high temperature section constant temperature time.
The beneficial effects of the present invention are：Simple structure, the ceramic membrane regeneration plant have it is safe and reliable, operation efficiently,
Low-loss feature, when the device occurs decaying or cannot still recovering after on-line cleaning for membrane flux when line is runed, leads to
Cross to the drying and dewatering of ceramic diaphragm and burn diaphragm, can effectively remove the pollutant of membrane removal surface attachment, under realizing offline mode
The thorough regeneration of ceramic film component recovers, and improve the contamination resistance of plate membrane bioreactor, it is to avoid general
The structural damage and damage easily occurred under soda acid cleaning method, and solve ceramic membrane and cannot change chronicity is dirty stifled
Learn cleaning thoroughly situation.
