Title: A process for melting down plastic-contaminated scrap with fractional decomposition of the organic fractions in a shaft furnace
Inventor: JESCHAR RUDOLF PROF DR ING
IPC: C21C5/52
Filed: 1993-02-27
Abstract: For melting plastic-contaminated scrap, predominantly motor vehicle scrap, the latter is coarsely comminuted, for example by cutting, and charged together with coke and additives to a shaft furnace. In a first preliminary shaft, the scrap is preheated to such an extent that predominantly the chlorine-containing decomposition gases escape from the plastics. These gases are extracted and processed. In a second preliminary shaft, the scrap is preheated further until the remaining, almost chlorine-free decomposition gases have been released. These gases of high calorific value are likewise extracted and then, after superheating in order to prevent condensation, utilized in the process itself. For this purpose, a part of this gas is burned in the blast tuyeres of the melting zone. Another part is used for indirect preheating of the scrap. For this purpose, the particular decomposition gas is fed in the heated state to the top of the two preliminary shafts. At the bottom of the shaft, the cooled gas is extracted again and heated, for example in a recuperator, by combustion of decomposition gases of the second stage. The gases of the two preliminary shafts are thus each circulated - for the major part. In each case the quantity of gas generated in the shaft by the decomposition is taken off from the circulating gases. After the decomposition of the plastics, the scrap passes into the actual melting shaft and is melted in the conventional way. The fractional decomposition of the plastics can, if appropriate, also ... in separate equipment outside of ... Original abstract incomplete.
