Candle filter vessel/ candle filter housing and filter sleeves
The general introduction of candle filters from Zonel Filtech:
The Candle filter from Zonel Filtech is a kind of pressure filter, the feeding port from lower side of the filter vessel, the solid particles be collected at the surface of the filter element and the filtrate go out from the inner core of the filter element to filtrate tank.
The operating procedures include: solution feeding, initial filtrate recycling, filtrate quality checking, filtration, cake washing and air blowing squeezing, reverse air blowing cake release, if the particles specific gravity higher, bottom side of the vessel may accumulate the slurry, then bottom size may design with filter board to help dry the slurry and help to handle the residual well.
The candle filter combined with filter tank, filter element plus filter sleeves, filtrate flow system, air wash and air squeeze system, reverse blow cake release system, cake discharge set, control cabinet and support shelf, etc.
The candle filter is operated in the sealing tank provide the safe operating environment, can be design to operation automatically, compact modularized structure, save the maintenance works, can be design to meet various industrial conditions and with the wide range of applications.

The properties of the candle filter from Zonel Filtech:
a. The candle filters from Zonel FIltech with big flow volume, can filter directly, or coated first with cake filtration to improve the filter efficiency, widely used for cake recycling, liquid concentrating applications, and the cake can be washed before recycle them, with a much higher purity.
b. The candle filter was with PLC controlled, the filter procedures like the solution feeding, prefiltration, filtering, raffinate draining, reverse blow cake release, cake discharge and so on will be arranged automatically.
c. Suitable for high precision (0.2 to 200 micron), high solid particles content (PPM level to 5%), sticky solution filtration.
d. The filter element/ filter candles distance is adjustable according to the cake thickness requested.
e. The filter housing of the candle filter is highly sealed, suitable for corrosive or some dangerous solution treatment.
f. The candle filter With optimistic drying design, can meet various moisture content requirements from different clients.
g. The candle filter is static design, easy to maintenance
