The candle filter is a system used for the reduction of polluting dust and fumes produced by melting furnaces.
Use: fume extraction and filtration.
Operation: the fumes, cooled in the heat exchanger, are sent to a pulse jet candle filter. The purpose of the candle filter is to collect the gas-borne oven dust and act as a fixed device for the de-acidification process.
For completely reliable operation with low pressure drop and long cartridge life the following features are set:
– Low air-to-fabric ratio
– Good distribution of the gas flow
Composition: The filter is composed of some cellular compartments. The compartment bottoms are equipped with trapezoidal hoppers (minimum slope 60 ° in one corner), with a screw conveyor across the discharge flange; the internal width of this flange is large enough to prevent any clogging. The hopper is equipped with a hatch access and an emergency branch discharge for connection to a mobile suction syste
The candles are vertical, with a round shape; they are made with ceramic elements.
