Candle Filter

Description

Candle filter is a more advanced, safe, efficient, pollution-free new filtration mode, candle filter has high efficiency and energy saving, closed and high precision, easy maintenance, safe and reliable, high degree of automation and other characteristics, can be widely used in petroleum, plastics, electroplating, chemical, ceramics, pharmaceutical, sugar and other industries of solid-liquid separation filtration. 

Candle filtration has gradually replaced the filter press and bag filtration as the mainstream filtration method, in which the repeated use of the filter medium has saved a lot of filter consumables. The cylinder is tightly sealed to ensure that the production process has no leakage. The microcomputer automation control is not only a good maintenance of the continuity of enterprise production, but also greatly reduces the risk of production accidents while improving production efficiency and saving labor.

Working Principle

When the liquid passes through the filter, the particle impurities in it are blocked on the outer surface of the filter element, accumulating to form a filter cake, so that the pressure difference between the inlet and outlet of the filter gradually becomes larger, 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 is getting smaller and smaller, the controller starts the backwashing action.

The liquid flows backwards from the inside of the filter element to the outside, taking away the impurities on the surface, using the reverse flow of the filter liquid to flush the filter cake on the outer surface of the filter element, when backwashing, The controller switches a set of valves of the filter to be backwashed, that is, close its inlet valve, and then open the sewage valve, part of the liquid of the filtration liquid reverse flow backwash the filter, quickly remove the filter cake on the surface of the filter element, discharge the residual liquid into the sewage collection pipeline, and then close the sewage valve, open the inlet valve, and return to the normal filtration state.
