The Candle Filter (Boilermaker Filter) is a fully automatic, vertical pressure filtration system. It uses unique "plum-blossom" shaped filter elements covered with specialized filter cloth.
Working Principle:
Adsorption & Filtration: Liquid enters the vessel. Under pressure, liquid passes through the cloth, while solids (carbon/catalyst) build up on the cloth surface, forming a "filter cake." The cake itself becomes the filter medium, achieving high precision (0.2 - 1 micron).
Drying: Once filtration stops, compressed air or Nitrogen is introduced to displace the liquid remaining in the vessel and dry the filter cake.
Back-blow Discharge: Clean gas is blown into the candle element from the inside out. The filter cloth expands, shaking off the dry cake, which falls into the bottom discharge outlet.
Key Technical Advantages
Zero Leakage: Hermetic design, suitable for volatile, toxic, or hazardous materials.
Dry Cake Discharge: Liquid content in the cake can be reduced to <20%, saving waste disposal costs.
No Residual Liquid: The unique "Zero-Heel" design ensures the bottom residual liquid is filtered completely via a bottom scavenger nozzle.
Cost-Effective: Manufactured strictly according to GB150 Standards, offering reliable quality at a competitive price compared to ASME-certified units.
