The candle filter has many advantages in the process of operation, namely, direct filtration, pre-coat filtration, cake recovery, slurry concentration, and filter cake washing. The candle filter is equipped with a variety of high The performance of the precision filter element enables direct fine filtration, the use of filter cakes formed by the impurity particles to filter more finely, and the cake has excellent peeling performance, with the highest precision of 0.2 micron.
The surface of the filter element of the candle filter is pre-coated with perlite and diatomaceous earth and other filter aids to effectively form a filter cake layer. The filter cake layer is mainly filtered by a filter medium, so that it can be To the extent that it achieves the clarification level of the filtering effect, it has high filtering accuracy, significantly improves product brightness, and has the outstanding advantages of operating cost economy.
The candle filter has a large filter area and excellent filter cake peelability. It can recover a large number of high-value filter cakes from a high-solids liquid at a time. If you add a dry design, you can obtain a dry cake with a moisture content of less than 20%. .
candle
The filter can, to a certain extent, be capable of periodically backwashing and continuously filtering the filter element without continuously discharging particles, continuously increasing the concentration of the particulate material in the filter to a certain concentration, and then Slurry discharge back.
The candle filter can directly wash the intercepted filter cake in the filter for many times, and can be added into the drying design to realize the integration of filtration, washing, drying, and unloading operations, reduce investment, shorten the process flow, and save energy consumption.
