TF Series Automatic Candle Filter System
TF Series Automatic Candle Filter System (TF Filter for short) integrates tubular filter elements inside. After the filter cake is built to certain thickness and the differential pressure reaches the preset value after filtration, the remaining liquid in the filter is discharged and then the gas is introduced to back-blow the filter cake off the filter candle, then filter candles are cleaned for the next filtration loop. TF Filter features wide application, close operation, multi-function, large filter area, high dirt holding capacity, easy filter cake back-blowing and automatic running. TF filter has 5 functions: direct filtration, precoat filtration, slurry concentration, filter cake recovery and filter cake washing. It can adapt to difficult service conditions such as high impurity content, viscous liquid, extreme high filtration ratings, high temperature and so on. Usually TF filter system runs continuously with two filters (one operation and another standby) and has PLC control system which can automatically carry out precoating, filtering, discharging, cleaning and other procedures. Several TF Filter units can be integrated as a large filter system.
LIVIC has developed 5 kinds of filter elements with high performance to meet various filtration requirements. Based on the different filter elements, TF filter is divided into 4 sub-series accordingly. TFC series, filter cloth type, TFV series, V-slot metal filter cartridge type, TFM series ,sintered ss candle type, TFE series, UHMWPE porous candle type. TFC series, supporting pipe wrapped with cloth in quincunx structure, during filtering, filtering cloth wrapped closely against the supporting tube external surface which can increase the filtration area and benefit for filter cake forming, reduce material waste.
