Description

The invention concerns a dust removal system for purifying gases from a carbide furnace. Polish patent no. 90965 describes a flue gas removal system equipped with a transfer filter, in which one of the feed components, preferably coke, used in the production process of the furnace whose flue gases are being dedusted, is used as the filtering material. The filter material, continuously collected by conveyors, moves vertically from the hopper through a container whose two walls are made of flat bars, allowing flue gases to flow through the filter layer. The dust removal system for purifying gases from a carbide furnace, according to the invention, has a transfer filter with a filter bed located inside the feed material hopper, in which the feed material level is continuously maintained automatically by an isotope sensor. An inlet funnel is located above the filter for introducing a portion of the feed material into the filter. The invention is illustrated in an example embodiment in the drawing, which shows a diagram of a dust removal plant for carbide production. The dust removal plant has a transfer filter 1 with a filter bed 2 located inside the feed material container 3. The raw material level is continuously and automatically maintained by isotope sensors not visible in the drawing, which ensures a constant material height. An inlet funnel 4 is located above the filter 1 to introduce a portion of the feed material into the filter 1. After passing through the filter 1, the filter material 2 combines with the remaining feed material from the container 3 and is transported by tightly enclosed conveyors to the furnace in continuous motion.
