The efficiency of ceramic filter is low. What's wrong with it?

Answer:

CleanThe cleaning of ceramic filter is divided into two parts: reverse flush cleaning (also useful gas) and combined cleaning. The purpose of cleaning is to discharge the particles from the hole to the ceramic filter board.Anti flushing and cleaning water filter after direct visual pressure can, generally between 0.08--0.12MPa, such as less than 0.05MPa, while the poor flushing effect without even washing effect, resulting in blocking accumulation eventually led to the ceramic filter plate hole plugging scrap. Replacing the filter element in time and ensuring the water pressure before filtration can provide stable backwashing water pressure.Combined cleaning by ultrasonic vibration, nitrate dissolution method for maximum remove blockage of backwash rushed out, the general ceramic filter every 8 hours of continuous work should stop cleaning 1 hours, such as the use of the old plate or the suction effect is poor, can strengthen cleaning (such as shorten the cleaning period, prolong the period of cleaning, increase the amount of nitric acid etc.).
Ceramic filter by vacuum suction effect in the ceramic filter plate to cake drying purpose, ceramic filter plate needs cleaning and life, if you discover that the slurry sucking effect is poor or even grout should first consider these three aspects:Ceramic filter plateTwo factors of ceramic filter plate most likely, respectively is the rupture and plugging holes: the rupture will lead to distortion and poor vacuum cleaning; plugging holes will cause the filter plate suction effect is poor even if grout, ceramic filter plugging hole, can strengthen cleaning (such as shorten the cleaning cycle, prolong the cleaning time, increase the amount of nitrate), such as strengthening the cleaning effect is still not improved, it should consider the life approaching should be scrapped and replaced with ceramic filter plate new (replacement plate should not put new or different manufacturers is mounted on the same line, best can complete change).Vacuum system failureThe vacuum degree of ceramic filter is usually about -0.085MPa. If the abnormal vacuum is found, the normal vacuum suction can not be provided, and the suction effect will be poor, or even the pulp will not be sucked.If the vacuum is abnormal, should adhere to the vacuum pump, vacuum connection pipe is whether the fault Water Leakage leakage, distribution valve friction sealing, ceramic filter plate is connected with the rubber tube is aging or exfoliation, ceramic filter plate rupture.
Ceramic filter is a new and efficient dehydration equipment. If users find the ceramic filter board surface suction effect is poor, or even do not suck slurry, we should promptly investigate the causes, so as not to affect production efficiency.
