    摘要: A device for improving waste vitrification in a disposable canister, the process for using the device, and the process for making the device. The disposable canister, also known as a module, has outer and inner containers with thermal insulation therebetween. The device includes an inner container of graphite having a layer of pyrographite on its external wall. The outer container is typically made of stainless steel. The inner container is heated, typically by induction, to melt the frit and waste. The melted mixture is then cooled to form a vitrified product in the module. The fabrication of the pyrographite coating on the inner container involves heating the container to about 1500 degrees centigrade in a methane atmosphere, then cooling the container to ambient temperature.

    摘要: The invention disclosed here is a starter tube for initiating a vitrification process for melting contaminated soils, waste products, and hazardous materials. The starter tube comprises a tubular sheath made of a flexible material. Received within the sheath is an electrically conductive starter material. The sheath is gas-permeable so that gases created by the starter material during commencement of vitrification will escape from the tube.

    摘要: A method and apparatus for treating cullet before use as a raw material in a glass manufacturing process is disclosed. The method includes providing a bed of cullet; passing hot gases through the bed, the quantity and temperature of gases being sufficient to pyrolyze odor creating impurities within the bed of cullet; entraining volatile products of pyrolysis into gases leaving the moving bed; heating the gases leaving the bed to oxidize odor creating impurities; and discharging the gases to the atmosphere. The apparatus includes a housing containing a moving bed of cullet; a source of hot gases which permits the gases to pass through the moving bed of cullet to pyrolyze odor creating impurities within the cullet and entrain volatile products of pyrolysis into gases leaving the moving bed; and an incinerator to remove odor creating impurities from gases leaving the moving bed.

    摘要: Lead-contaminated soil and battery casings are remediated using a plasma arc furnace which pyrolyzes the soil and waste battery casings so as to form a vitrified slag and a combustible gas, respectively. The combustible gas along with volatilized lead (and other heavy metals which may be present) are transferred to, and used as a primary fuel by, a conventional smelting furnace. The volatilized lead that is entrained in the combustible gas is thus transferred to the recovery and environmental protection/control equipment associated with the smelting furnace or other conversion system. The soil, on the other hand, is converted into a non-toxic (i.e., according to the Toxicity Characteristic Leaching Procedure) vitrified slag by the plasma arc which may be crushed and used as a commercial material (e.g., roadway aggregate, asphalt filler material and the like) or simply transferred to a landfill where it poses no environmental threat.
