Candle filter is a kind of automatic filter equipment. Candle filter is a filter that uses the filter cartridge as the skeleton. The filter medium are the filter cloth and filter cake layers that covering the filter cartridge, and uses pump pressure to achieve liquid clarification.
Candle filter can choose different filter materials according to the filter medium, filter precision, filter residue viscosity and so on.

Candle filter is mainly composed of cylinder, filter cartridge, filter cloth, filter aid, PLC control system and other accessories. Other auxiliary equipment includes air compressor, pump, etc. The material of cylinder and filter cartridge is mainly stainless steel (304/316/321), carbon steel, titanium, the material of the filter cloth is mainly PP (polypropylene), PE (polyester), PPS (polyphenylene sulfide), PTFE (polytetrafluoroethylene), nylon fiber, etc. The amount of filter agent added is different according to different processes. The recommended ratio is between 1% and 3%, mainly including activated carbon and diatomaceous earth.
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. 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.
