Product Description

TZS Series Candle filter, also known as a candle diatomaceous earth filter, is a self-cleaning filter specifically designed for solid-liquid separation. It is typically used for clarifying and recovering liquids with solid content ranging from 5% to below 1%, or even trace amounts.

TZS Series Candle filter features wide application, close operation, multi-function, large filter area, high dirt holding capacity, easy filter cake back-blowing and automatic running.

Work Principle

The candle filter is closed and composed of multiple porous filter cartridges (candle filter cartridges), and the filter cartridge is covered with a matching filter cloth. During the liquid circulation process, large particles of material are trapped on the surface of the filter cloth.

When these solid substances reach a certain thickness, the so-called "filter cake layer" is formed. Because the gap between the particles in the filter cake layer is very small, the escape of particulate impurities in the liquid is blocked, so that the filtrate becomes clear and the filtration effect required for production is achieved, so the candle filter is also called the filter cake layer filter.

When the filter cake layer exceeds a certain thickness after normal filtration for a period of time, the rate of filtrate passing through the filter cake layer decreases, and the filtration efficiency becomes poor, and the "filter cake layer" needs to be removed. At this time, the system will perform backflushing according to the signal provided by the pressure sensor.

To remove the cake, open the valve at the bottom of the cylinder to discharge slag, and then rebuild a new "filter cake layer" to start a new round of filtration cycle.
