Sugar Industry Candle Type Filter Automatic Slag Discharge Ss316

Automatic Slag Discharge Ss304 Material Candle Filter For Sugar Industry

Candle filtration has gradually replaced pressure filtration and bag filtration as the mainstream filtration method. The repeated utilization of filter media saves a lot of filtration consumables; The cylinder is tightly sealed to ensure no leakage in the production process; Microcomputer automatic whole process control not only better maintains the continuity of enterprise production, but also greatly reduces the risk of production accidents while improving production efficiency and saving labor.

Working principle of candle filter:

When the liquid passes through the filter, the particle impurities are blocked on the outer surface of the filter element and accumulate to form a filter cake, which gradually increases the pressure difference between the inlet and outlet of the filter. When the pressure difference reaches a certain default value (150kPa), it indicates that the filter cake reaches a certain thickness. At this time, the filterable flow of the filter element becomes smaller and smaller. The controller starts the backwashing action, and the liquid flows backward from the inside of the filter element to the outside to take away the impurities on the surface, The filter cake on the outer surface of the filter element is washed by the reverse flow of the filter liquid. During backwashing, the controller switches a group of valves of the filter to be backwashed, that is, close its inlet valve, and then open the blowdown valve. Part of the liquid of the filter liquid flows in reverse to backwash the filter, quickly remove the filter cake on the surface of the filter element, discharge the residual liquid into the sewage collection pipeline, then close the blowdown valve, open the inlet valve and return to the normal filtration state.

• Fully closed filtration. No leakage. No any environmental pollution.
• The entire process can be fully automated.
• The filter cake can be washed and dried to obtain maximum economic benefit.
• The filter element is designed to be the duplex structure.
• It has a wide applications and better filtering effects.
• It is the gas blowback slagging. The slag can be discharged quickly and cleanly.
• It is suitable for a variety of sticky materials.
