Abstract:
A processing apparatus capable of separating and recovering resins and metals, respectively, from an object being processed, which has resins and metals as its constituent, comprises a first gastight area (102), in which temperature and pressure are regulated so as to permit selective thermal decomposition of resins from the object (150) being processed, a second gastight area (103), which is partitioned from the first gastight area by an openable and closeable partition (105C) and in which temperature and pressure are regulated so as to permit selective vaporization of metals from the object, first recovering chamber (111) connected to the first gastight area for recovering gases produced by thermal decomposition of resins, and second recovering chamber (115) connected to the second gastight area for recovering vaporized metals.
Abstract:
A treatment method includes heating a treatment target object under reduced pressure in a hermetic zone to vaporize a component of the treatment target object, and opening a hermetic door and inserting a tube from a side of a treatment system for the vaporized component adjoining the hermetic zone with the hermetic door therebetween such that the tube shields the hermetic door from the hermetic zone to introduce the component vaporized from the treatment target object to the treatment system side.
Abstract:
A sound absorbing structure including a sound absorbing member, an air layer, and a resonant sound absorbing structure. The air layer is formed in the rear of the sound absorbing member. The resonant sound absorbing structure includes a slit and is formed in the rear of the sound absorbing member. The sound absorbing member is a surface plate covering the rear air layer and the resonant sound absorbing structure, and the sound absorbing member is shaped in one of a plate and plane.
Abstract:
A processing method by which metals may be recovered at a high purity from metal-containing waste materials. The method for processing metal-containing waste materials comprises crushing a metal-containing waste material to a particle size of 1-50 mesh, separating and recovering the metal-containing particles from the crushed portion, introducing the metal-containing particles into a vacuum heating furnace, pre-heating the furnace while under suction evacuation, and then raising the temperature of the furnace in stages while continuing the vacuum suctioning, recovering the metal and non-metal vapor produced at each temperature level using a condensing and adsorbing means, and recovering the liquated metals as melts. The method may be used to process waste batteries, copper-containing waste materials and the like in the same manner to recover high-purity metals.
Abstract:
A method for recovering substance such as zincing or the like adhered to the surface of an object to be processed, by causing such materials to be evaporated in a vacuum. In this method, the object to the processed is placed in a furnace provided with heating means; the temperature within the furnace is elevated up to a predetermined level with the aid of an oxidizing gas atmosphere; the pressure in the furnace is reduced so that the quantity of the oxidizing gas is reduced to be below the explosion limit; and vaccum or a reducing gas atmosphere is fed into the furnace to reduce the oxidization of the object to be processed. Thereafter, the interior of the furnace is evacuated while being maintained under a predetermined evaporation temperature condition; and the substance evaporated from the object to be processed is passed to recovery means provided in communication with the furnace, so that the substance thus evaporated is condensed in the recovery means and recovered therefrom.
Abstract:
A treatment apparatus of the present invention includes a hermetic door 115b and a retort 115c as an interface for taking out a gaseous emission containing vaporized substances from an object to be treated which is being heated in a reduced pressure state in a second hermetic chamber 103 while maintaining conditions in the second hermetic chamber. When the retort 115c is inserted into a first opening 103b of the second hermetic chamber, the hermetic door 115b in an open state is shielded from the second hermetic chamber 103, whereby condensation of the gaseous emission at the hermetic door is prevented. Accordingly, condensates can be taken out while conditions such as temperature and pressure in the hermetic chamber are maintained without the treatment apparatus being stopped. The productivity of treatment is greatly improved by continuous operation of such a treatment apparatus.
Abstract:
An object to be treated such as soil, burned fly ashes, or the like containing organic halides is introduced to a hermetically sealable thermal decomposition furnace 310 and heated under reduced pressure. Emitted gases of the object to be treated are treated so that the generation and recomposition of dioxins are supressed. A heated residue of the object to be treated is cooled after being purged with a purge gas which is organic halide-free and has no organic halide generating capacity. Thus, the concentration of organic halides remaining in the heated residue can be held to an extremely low level.
Abstract:
Resupply, recycling and exchange of consumption items of office apparatuses made by two or more manufacturers can be facilitated by a customer support center, a supply center, office systems and customer support terminals connected via a communication network, wherein an apparatus management database, a cost and supply information database, an analysis database, and a supply management database are installed at appropriate locations, each associated with functional units such as a data acquisition unit, a data analysis unit, a report generating unit and the like for issuing purchase orders, recycling orders, exchange orders and office system improvement proposals.
