Henan Dazhang Filter Equipment Co., Ltd.

A candle filter is a closed-loop precision filtration device with multiple candle-shaped filter elements installed inside. It achieves solid-liquid separation through pressure filtration. The equipment features high filtration accuracy, good sealing, and a high degree of automation, making it suitable for fine filtration processes. Working principle: Liquid containing solids enters the filter. Under pressure, it passes through the surface of the filter element. Solid particles are trapped and form a filter cake, while the filtrate flows out through the filter element. After filtration, the filter cake is removed by backflushing or vibration, achieving continuous filtration operation. Advantages: High filtration accuracy, clear filtrate; closed filtration avoids contamination; high degree of automation; compact structure, small footprint; suitable for filtering high-value products. Disadvantages: Relatively small throughput; not suitable for materials with high solids content; relatively high filter element cost; not suitable for coarse particle filtration. Main uses: Fine chemical filtration; edible oil filtration; pharmaceutical liquid filtration; catalyst recovery; solvent and resin filtration. Application industries: Chemical industry; food industry; pharmaceutical industry; petrochemical industry; new energy materials.
