摘要:
A blasting method of blasting an explosive device at least containing an explosive and a chemical agent in a sealed pressure vessel that prevents soot generation during blasting and improves an efficiency of decomposing the chemical agent. First, a transported chemical bomb (explosive) 100 is placed and sealed in a blasting chamber (pressure vessel) 10. The blasting chamber 10 is then brought into a reduced-pressure or vacuum state by aspiration of the air therein by using a vacuum pump 13a and oxygen is supplied through an injection port 12 into the blasting chamber 10 to a pressure of 15 to 30% of atmospheric pressure. The chemical bomb 100 is then blasted, as it is ignited by an ignition device not shown in the Figure.

A reactive waste deactivation facility capable of continuously processing a wide spectrum of hazardous waste includes a building (10) having an outer perimeter defined by a plurality of deactivation bays (A1-A4, B1-B4, C1-C4) each including means for deactivating hazardous wastes. One or more expansion chambers (20, 98), are surrounded by the plurality of bays and are commonly connected to an air pollution control system (24). The deactivation bays are connected with the expansion chamber by means of plurality of expansion ducts (22, 98, 104) 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 (18) 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.

The design of a lightweight and compact furnace used for the treatment of wastes is disclosed. The furnace has been designed specifically for use in applications where the weight of the furnace must be minimized and where the available space for installing the furnace is limited. The furnace consists of three main chambers. In a first chamber (12), the water and the organic compounds are dissociated and vaporized and the metals and ceramics are vitrified and transformed into molten slag. A plasma torch (18) or an induction coil can be used to provide the energy required for this operation. In the second chamber (28), the dissociated and vaporized compounds are burned in air or oxygen using a plasma torch (32) to supplement the energy requirements. The third chamber (38) receives and stores the vitrified slag. The furnace disclosed herein uses a unique lightweight, multilayered, hot chamber wall construction which incorporates advanced materials to provide both high energy efficiency and a dynamic cooling control. The lightweight wall construction used for the furnace is an essential feature of the present invention.

Known disposal devices are unsuitable for the disposal of toxic materials and can only be operated discontinuously, and repla cement of wearing parts is complex and costly. The proposed device is constructed in such a way that at least the inner lining of the explosion and combustion chamber (4) is made from stacked steel rings (5) which when joined form an upper inlet aperture (3) of the explosion and combustion chamber (4) through which hazardous material is introduced and a lower outlet aperture (6) for the produced waste; the inlet aperture (3) of the explosion and combustion chamber (4) can be closed off by a steel block (10) which can be lowered in the lock chamber (1). The device is suitable among other things for the disposal of explosives and toxic materials.

Zur Aufarbeitung von pyrotechnischem Material brennt man dieses pyrotechnische Material in einem ersten Reaktor ab und läßt es ausschwelen, trägt die bei der Verbrennung entstehende Schlacke aus und leitet das bei der Verbrennung entstehende Rohgas in einen Feststoffabscheider, um feste Bestandteile abzutrennen, leitet das von festen Bestandteilen befreite Rohgas in einen zweiten Reaktor, in dem es auf eine Temperatur von mehr als 800°C erhitzt wird, leitet anschließend das Rohgas in mindestens eine Waschvorrichtung zur Naßwäsche, beaufschlagt das gewaschene Rohgas mit einem Additiv, das aus einer Kalk-Kohle-Mischung besteht, leitet dieses Rohgas anschließend durch eine Filtereinheit und entläßt das so gereinigte Gas dann als Abluft.
摘要:
An incineration tray (1) for burning away explosive substances has a base plate (4) on which is mounted a trough (2) of scale- and high temperature-resistant material for containing the explosive substances. To obtain a combustion tray which withstands the enormous, erratic increase in the heat developed during combustion of the explosive substances so that it remains substantially dimensionally stable and can thus in particular be frequently re-used, the trough (2) is mounted at a distance from the base plate (4) on pillar-type supports (6) quincuncially arranged. As a result of these two measures, the forces generated by the thermal stresses set up in the material during combustion are diverted through the supports (6), and in addition the high temperatures of up to 3000 °C produced during combustion are restricted mainly to the trough (2) due to the fact that the space between the base of the trough and the base plate (4) acts as a cooling, temperature-reducing space.
