Q:The working principle of ceramic filter
Based on the work principle of ceramic filter function of the capillary, by using porous ceramic as filter media, a large number of small capillary action with solid-liquid separation equipment design principle using microporous ceramic disc filter in negative pressure, working conditions, characteristics of the microporous ceramic filter plate with its unique water impermeable, extraction of ceramic filter plate and external vacuum cavity the differential pressure tank suspension material under the action of negative pressure adsorption in the ceramic filter plate, solid material can not through the microporous ceramic filter plate is retained on the surface of the ceramic plate, and the liquid due to the hydrophilic effect of vacuum pressure difference and the ceramic filter plate is passed into the gas-liquid distribution device (vacuum barrel) efflux or recycling so as to achieve the purpose of solid-liquid separation.
Q:Principle of chemical engineering drum vacuum filter, the faster the speed, the less the amount of filtrate obtained per turn, the more the amount of filtrate obtained per unit time?
The faster the speed is, the shorter the time required for each turn, i.e., the shorter the filtration time, the less the filtrate will be
Q:What is the reason that ceramic filter does not absorb mineral powder?
There may be a failure of the filtrate pump, the diaphragm of the pump is damaged, and the mechanical seal of the pump is invalid
Q:Microporous ceramic filter plate cleaning
In order to avoid the possibility of plugging, ceramic filter plates with suitable aperture range of different manufacturers can be selected.
Q:The vacuum of ceramic filter is not enough
The vacuum degree of ceramic filter is about -0.08MPa, if the ceramic filter is less than 0.06MPa, the vacuum is not enough. If the vacuum of ceramic filter is not enough, it will influence the suction effect of ceramic filter (mainly the thickness of filter cake and water content of filter cake).
Q:The vacuum degree of the ceramic filter is normal and the cake water is large?
There is a difference between the vacuum display and the actual vacuumThe main speed of the ceramic filter is too fastThe water content of the filter cake is gradually increased within 0~8 hours after the equipment has been continuously turned onThe ceramic filter plate does not meet the aperture range and the opening rate is lowThe ceramic filter plate has a near life and serious blockageCeramic filter cleaning standards (acid, ultrasonic, backwash water)The scraper can not be completely discharged, and the surface of the ceramic plate is coated with a thin filter cakeFailure to manufacture equipment or other causes of failure
Q:Is the filter plate of the ceramic filter afraid of freezing?
In addition, the temperature is one of the factors affecting the filter suction effect of ceramic filter. The lower the temperature, the worse the suction effect.Therefore, the ceramic filter plate, especially the ceramic filter plate after use, should be protected under low temperature environment.
Q:Ceramic filter suddenly do not smoke, a little later on their own good, what reason?
The size of ceramic filter is generally on both sides of the vacuum tank, such as 50 square meters with 5 square meters of ceramic filter / ring ceramic filter plate combination (possible), there are 10 discs, the ceramic plate left a vacuum tank on the left of the 5 disc for filtration, vacuum filtration tank for the ceramic plate on the right right of the 5 disc. If a vacuum system temporarily fails, it may cause poor suction, no suction, and a normal operation at the other end.
Q:Ceramic filter fineness thin mud suction is not what to do more
With ceramic filter to treat pulp dehydration, the particle size is too large, the particles are easy to precipitate, the particle size is too small, too much mud, then the water content of the filter cake will increase, and the life of the ceramic filter plate will be reduced.
Q:The ceramic filter suddenly did not smoke, and later he was all right. What's the reason?
How old the general ceramic filter suction main reason mud cake thickness is not much of a ceramic filter plate is different, because the ceramic filter backwash water, vacuum suction and nitrate are through the distribution valve, are often the same boat". See your description, you do not know the 5 line is about "5 disc or sideways 5 rows of ceramic plates, that is completely not suction or suction effect is poor, I hope to help you:
