Description
Affiliated technical field
The present invention relates to method and device that ceramic filtering plate is cleaned on the ceramic filter.
Background technology
Ceramic filter is a capillary principle of utilizing ceramic capillary, and-------permeable airtight and solid-liquid separating equipment of design, the ceramic capillary size is generally at 0.1～10um.In the production use, filter cake is adsorbed on the ceramic filtering plate surface, and filtrate is sucked away by the ceramic filtering plate micropore.The reciprocation cycle of process like this, in micropore, form chemical fouling and machinery obstruction (depositions such as particle and glutinous mud) inevitably, though this equipment has designed the nitric acid cleaning, ultrasonic wave cleans and the water purification back purge system, and used once in per 8～10 hours, but to different filtering objects, blockage problem still often takes place, at least less than one month, less than 1 year, discard because of stopping up fully at most once the cover ceramic filtering plate.So just problem that the article of a piece " cleaning practice of ceramic filter and discussion " by name of the 24th phase the 1st volume 34-37 page or leaf publication of publishing " mining metallurgical engineering) " in February, 2004 is discussed.In incomplete obstruction process, throughput of filtration has been subjected to very big influence, and more transducer set ceramic filtering plate expense is also very expensive, more than 5000 yuan of average every square meter.
The obstruction of ceramic filtering plate has not only increased operating cost to the user, simultaneously the market development of manufacturing enterprise and the extensive use of this energy-conserving and environment-protective equipment all has been subjected to serious restriction.Also just because of this reason, at present international and domestic ceramic filter equipment manufacturers all optionally sell by test the user of need Separation of Solid and Liquid.
Summary of the invention
The purpose of this invention is to provide a kind of online washing method and device of ceramic filter, ceramic filtering plate is cleaned, the micropore of mediation ceramic filtering plate is to recover filtering function.
Method of the present invention is achieved in that it comprises the steps:
(1) with the ceramic filter parking, the blowing that run well, remove the silt particle in ceramic filtering plate, rotor and the cell body on the ceramic filter, and water cleans up;
(2) filter is set at the pickling pattern, cleaning agent is entered ceramic filtering plate by counter-flushing pipeline, the micropore through ceramic filtering plate flows to cell body again;
(3) be interrupted the startup ultrasonic wave and clean, with circulating pump the cleaning fluid in the cell body is extracted out simultaneously, after filtration, be back to filter plate by counter-flushing pipeline again;
(4) stop to clean, discharging cleaning fluid and water recoil Xian remove the cleaning fluid that remains in the filter plate.
Be used to realize that the device of method of the present invention comprises:
A circulating pump is used for extracting the cleaning fluid in the ceramic filter cell body;
, a feed tube, the one end communicates with the ceramic filter cell body, and the other end communicates with above-mentioned circulating pump inlet;
, a drain pipe, the one end communicates with above-mentioned circulating-pump outlet, and the other end communicates with the inlet of ceramic filter feed liquor distributing valve;
A filter that is installed on the drain pipe is used for filtering the cleaning fluid from the ceramic filter cell body.
During cleaning, filter is arranged on the pickling pattern, filter rotates under zero load, and cleaning fluid is pumped in the ceramic filtering plate inner chamber by ceramic filter recoil Xian Guanlu, and the micropore through ceramic wafer flows to cell body again.Be interrupted and start the ultrasonic wave cleaning, when treating the interior cleaning fluid height of cell body near overfall, the ON cycle pump, cleaning fluid is turned back in the filter plate inner chamber after filtration by cell body again, make cleaning fluid under certain pressure by ceramic filtering plate in to outer flushing, treat when producing the filter plate surface liquid rapid draing of cell body, show that filter plate has recovered filtering function, clean and finish, stop circulating pump, the discharging cleaning fluid.
For the cleaning fluid of can providing and delivering easily, device of the present invention also comprises a cleaning fluid liquid dispensing device, and this device comprises:
A basin that is used for depositing concentrated cleaning agent;
One is used for from the pump of above-mentioned basin extraction cleaning agent;
A complex acid bucket that is used for depositing the cleaning agent that is extracted by basin is provided with level-sensing device in the bucket, and the liquid that enters bucket is measured;
A measuring pump is used for the cleaning agent in the complex acid bucket is pumped in the above-mentioned cleaning fluid wash cycles device.
Advantage of the present invention is to make cleaning fluid by the wash cycles incessantly from the inside to the outside of capillary micropore on the filter plate by circulation, is equipped with ultrasonic wave and cleans, and improves the service life of filter plate, can enlarge the scope of application of ceramic filter.Another advantage of the present invention is can improve the pressure of cleaning fluid in filter plate by circulating pump, is convenient to cleaning fluid and penetrates micropore on the filter plate, so that cleaning fluid contact the raising cleaning performance with dirt in the micropore.
