Abstract:
A reactive waste deactivation facility capable of continuously processing a wide spectrum of hazardous waste includes a building having an outer perimeter defined by a plurality of deactivation bays each including means for deactivating hazardous wastes. One or more expansion chambers are surrounded by the plurality of bays and are commonly connected to an air pollution control system. The deactivation bays are connected with the expansion chamber by means of plurality of expansion ducts each having closable exhaust ports therein such that each inactive deactivation bay may be isolated from the expansion chamber when one active bay is in operation. A computer control system provides for sequencing of operation of said deactivation means in the plurality of bays, as well as among other things, controlling the exhaust ports, to effect continuous processing of hazardous wastes in order to provide a selected output of emission gases to said expansion chamber and air pollution control system.
Abstract:
A method and an apparatus for disposing wastes comprising the steps of conducting a hydrothermal decomposition reaction of the wastes, separating the products into a solid fuel and waste water, combusting the solid fuel, scrubbing the combustion gas, generating steam using the heat generated by the combustion, and purifying the waste water, exhibit a high energy-efficiency, while exhibiting a high removal rate of the pollutants generated during the combustion.
Abstract:
[Problem] To provide a rotating classifier which can keep classification performance high and which can prevent blockages caused by biomass and the like.[Means for Resolution] The rotating classifier is characterized in that: comb teeth-like protrusion portions protruding toward a fixed member side are provided on top of rotary classification fins at intervals along the circumferential direction of the rotating classifier fins; a first gap is provided between an upper end portion of each of the comb teeth-like protrusion portions and a lower surface of the fixed member; a second gap formed between a protrusion portion and a protrusion portion adjacent to the protrusion portion is connected to the first gap; and an air stream flowing from the radial outside to the radial inside of the comb teeth-like protrusion portions through the first gap and the second gap is formed due to the rotation of the rotary classification fins.

Abstract:
Waste processing system including a shredder, a grinder and a steam explosion device such as a cooking extruder. The waste processing system is used to process raw waste, such as consumer waste, into an end product such as pellets. One potential use for these pellets is pyrolization to form biogas. Because of the uniformity composition of the processing waste (see DEFINITIONS section), imparted by the shredder and grinder, and because of the uniformity of distribution of plastic in the processing waster, imparted by the steam explosion processing, the end-product made by systems according to the present invention are superior with respect to several physical characteristics and especially well suited for pyrolization to make biogas.
Abstract:
The present invention provides a high temperature treating method for inflators for an air bag with an excellent workability. The present invention is a high temperature treating method for inflators for an air bag provided with a step of cutting and removing wire harnesses connected for inflator actuation, a step of performing grouping according to main metals constituting inflators, and a step of charging the inflators which have been subjected to treatment in the preceding steps into a thermally treating tower to conduct thermal treatment at a temperature at which gas generating materials inside the inflators burn and the main metals constituting inflators do not melt.
Abstract:
A system and process to provide integrated control for the pyrolytic composition of organic (biomass) waste products especially for municipal solid waste systems. The system includes integrated control that monitors biomass waste stream throughout the entire system and the products produced therefrom and includes presorting, controlling the amount of material processed in a continuous manner, shredding, removing moisture in a continuous process that is controlled and providing the waste stream to the distillation unit for pyrolytic action where it is converted into gaseous fuel and a char residue. The gaseous fuel is scrubbed clean and monitored and stored and reused to provide heat to the system. The entire system may be self-sustaining and continuous with very little or no human intervention. An integrated real time computer control system includes sensors and measuring devices with all the major components to ensure integrated efficiency.
Abstract:
A method for decontaminating both soil and mixed waste water polluted by hydrocarbons in a single integrated process is disclosed. Contaminated mixed waste fluid is separated into water and hydrocarbons which are then used in the thermal decontamination of polluted soil through the volatilization of hydrocarbon contaminants. Flue gases containing the volatilized hydrocarbons from the thermal soil decontamination undergo oxidation. Thermal energy from the soil decontamination process and the thermal oxidization of the flue gases can be recovered and used to facilitate the separation of hydrocarbons and water. In this integrated system, every by-product of each step is either decontaminated or consumed in another operation of the system. Energy conservation within this system is also realized by the use of heat exchangers to transfer energy from where it is created by the process to where it is used elsewhere to enhance efficiency within the process. It is possible to run this apparatus and process so that the only outputs of this system are decontaminated soil and clean exhaust gases.
Abstract:
In the case of a process for treating residues and waste materials, in particular household, commercial, and industrial trash, in a first step in the process these materials are treated thermomechanically, for example in a worm extruder, that is, in particular, heated, separated into fibers, and brought to a solid state. Then the materials in the solid state are separated selectively and subjected to a further recycling treatment.
