摘要:
The bin of the invention can be used to incinerate waste for a period of more than fifteen minutes in an incinerator without the waste being pre-melted, in particular as it is being inserted into the incinerator. The bin is mainly formed by a fibreglass casing (10) and is preferably reinforced with a lightweight metal structure (12) positioned outside or inside the casing or built into same. The assembly is topped with a gripping handle (14) and the upper portion of the assembly is stiffened by a metal tube (16) to which the lightweight metal structure (12) is secured, with a base formed by a drip pan (18) being secured to the base of the lightweight metal structure (12). The invention is suitable for the incineration of toxic waste.
摘要:
The invention relates to an induction melting furnace comprising shell (7) and a lower sole (11) forming the main part of the structure. In addition, the furnace comprises a removable inner crucible (1) formed by an inner layer (4) that is resistant to heat and to the aggressive nature of the molten bath (20), an outer layer (6) defining the crucible, and an intermediate insulating layer (5). The crucible (1) is a single-use crucible and can be stored, together with its charge, in a suitable container. Heat losses are low, even if the shell (7) is cooled. In addition, stresses due to differential thermal expansions are also very low.
摘要:
The method according to the invention makes it possible to use a rather small facility to incinerate, melt and vitrify mixed waste (30) introduced into a reactor (10), using a basket (18) which in turn passes through an airlock (12). Plasma torches (14) burn all of the waste (30) contained in the basket (18). Said waste is then lowered into a molten bath of a furnace (20) with an inductor (24) comprising a container forming a crucible (23). The facility is completed by a combustion gas treatment chain. The furnace (20) can be disassembled, after a treatment series of several baskets (18) of waste (30), to disassemble the crucible-forming container (23) from the furnace (20). The invention is applicable to the treatment of various radiologically contaminated and/or toxic mixed waste.
