Sintered porous candle filter, also known as sintered powder candle filter, is made of sintered metal powder after pressing, forming and high temperature sintering, featuring stable shape, good air permeability and great separation effect.
The pore size, distribution, strength and air permeability of the sintered porous candle filter depends on the powder fineness, compacting and sintering processes. Our sintered porous candle filter achieves a filter rating of 0.1–100 μm.
The most commonly used sintered metal materials are stainless steel and bronze. In addiction, titanium, nickel, Monel and other materials are available upon request.
The filtrate enters at the bottom of the filter and moves upward, which helps to keep the solids in suspension so that they are evenly deposited on the surface of the filter elements. Impurities are retained on the surface of filter elements, and clean filtrate is discharged from the filter through the register. When the filter reaches the set pressure value, the control system stops feeding and the residue liquid in the filter is drained out. The backblowing begins. When the backblowing is finished, the dry cake is discharged from residue discharge nozzle. Close the residue discharge nozzle when the dry cake discharging is finished. The surface of the filter elements is clean and ready for the next round of filtration.
Compared with polymer melt filtration, chemical filtration requires low temperature and low pressure. So, sintered porous candle filter has a diversity of connection types. Connection types are customized upon request.
