Abstract
The present invention relates to a n on-line recycle cleaning method of ceramic filter and its equipment. Said method includes the following steps: (1), stopping ceramic filter, discharging slurry and cleaning with water; (2), adopting acid pickling mode to make the cleaning fluid be fed into ceramic filtering plate by means of reverse-washing pipeline; (3), intervally starting ultrasonic cleaning device to make cleaning operation, at the same time using circulating pump to pump out the cleaning fluid from the filtering channel body interior, filtering said cleaning fluid and making the filtered cleaning fluid be returned into filtering plate by means of reverse-washing pipeline; and (4), stopping cleaning operation and removing residual cleaning fluid from filtering plate interior.
Description
Technical field
The present invention relates to the method 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 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), remove the silt particle on the ceramic filtering plate surface on the ceramic filter, the silt particle of rotor surface and the silt particle in the cell body, and water cleans up with the ceramic filter parking, the blowing that run well;
(2) filter is rotated under zero load, cleaning agent is entered in the ceramic filtering plate inner chamber 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 in the filter plate inner chamber by counter-flushing pipeline again;
(4) stop to clean, the discharging cleaning fluid is also used water backwashing, removes the cleaning fluid that remains in the filter plate.
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.

The specific embodiment
As shown in Figure 1, on-line cleaning device of the present invention comprises cleaning fluid liquid dispensing device 1 and cleaning fluid wash cycles device 9 two parts, and cleaning fluid liquid dispensing device 1 comprises basin 2, pump 3, complex acid bucket 4 and measuring pump 5.Cleaning fluid wash cycles device 9 comprises feed tube 14, circulating pump 13, filter 11, discharging tube 8.Its cleaning process is as follows:
With the ceramic filter parking, the blowing that run well, remove ceramic filtering plate 17 surfaces and the silt particle of rotor surface and the silt particle in the cell body 15 on the filter, and rinse well earlier with clean water.The cleaning agent that concentrates that will not contain nitric acid with pump 3 is pumped to the complex acid bucket by basin 2, is provided with level-sensing device in the complex acid bucket, is used for measuring and once cleans required cleaning agent consumption.When treating that the complex acid liquid in bucket reaches set amount, pump 3 is shut down.Filter is set at the pickling pattern, starts the pickling pattern.Measuring pump 5 pumps into the cleaning agent in the complex acid bucket in the discharging tube 8 of cleaning solution circulating device with in the woven hose 6 and mixes from the nitric acid liquid of ceramic filter pickling liquid mixing system by check valve 10, send into counter-flushing pipeline by discharging tube 8 and enter in ceramic filtering plate 17 inner chambers, the micropore through ceramic filtering plate flows to cell body 15 again.When treating that cleaning fluid height in the cell body 15 is near overfall, be interrupted and start ultrasonic transducer 16 cleanings, can be arranged to 20 minutes break time/per hour, while ON cycle pump 13, by feed tube 14 cleaning fluid in the cell body 15 is extracted out, return in filter plate 17 inner chambers by discharging tube 8 after process filter 11 filters out the impurity that cleans out, discharging dirt pipeline 12 is housed on the filter 11.Pressure gauge 7 is housed on the discharging tube 8, is used for measuring the hydraulic pressure of cleaning fluid in filter plate, in order to improve cleaning performance, the hydraulic pressure of cleaning fluid is at 1～1.5Kgf/cm
2Developing result is better under the pressure.Cleaning fluid washes the concrete time can be according to filter plate surface appearance decision, and general about 1～3 hour of the time spent, it is very fast when dry to be adsorbed on its surperficial liquid after filter plate is produced by cell body, show the penetrating ability recovery of filter plate better, can clean end, stop circulating pump, the discharging cleaning fluid.Start backwashing procedures, water carries out backwash, stops behind the rinsing number minute, can change normal production over to and filter operation.
