    摘要: An assembly is provided for purifying toxic gases from production processes by thermal conversion in a reactor chamber and subsequent treatment of reaction products with a sorption agent in a washing device in order to bind water-soluble reaction products and to elute solid reaction products. The reactor chamber has an external wall and an internal wall, the internal wall tapering at its base in the form of a funnel at a predetermined angle. A unit for thermal treatment of toxic gases is located on the reactor chamber, sealing the top of the chamber. An inner face of the internal wall of the reactor chamber comprises a film of water flowing downwards in a uniform manner. The exterior of the internal wall is surrounded by a cloak of water. A waste gas outlet and a connection for a water circuit are located at the lower end of the tapering internal wall.

    摘要: The continuous furnace serves for the simultaneous two-sided sintering of sintered sheets upon substrates. It has a muffle and a conveyor belt longitudinally traversing the muffle and carrying the substrates and consisting of a pair of individual belts which are guided in parallel next to each other and synchronously. The belt surfaces are mutually inclined at a small angle to the horizontal in the muffle. The substrates which are self-supporting between two parallel lateral edges, lie with one lateral edge on the belt surface of one individual belt and with the second lateral edge on the belt surface of the other individual belt, so that the bottom side of the substrate does not touch the individual belts.

    摘要: Anhydrous, solid Raney catalysts in fusible, organic embedding media prepared by initially introducing a Raney catalyst slurry into a vacuum mixer under an inert gas atmosphere, admixing the embedding medium, removing the main quantity of the water at temperatures below the melting point of the embedding medium and removing the residual water above the melting point of the embedding medium in vacuum while maintaining mixing. After the dehydration, the vacuum is terminated by applying an inert gas and the product where called for is shaped into low-surface molded bodies.

    摘要: An apparatus for purifying waste gases, particularly waste gases from CVD (chemical vapor deposition), plasma etching or similar processes, with at least one combustion space, which is in a vertical arrangement within an outer pipe and is limited at the top by an umbrella-like cover, and an internally or externally mixing burner, the combustion gas nozzles of which protrude into the combustion space, combustion gas, oxygen or air and waste gas being supplied to the burner, as well as to means for supplying and discharging oxidizing agents and/or absorbents to a scrubbing space above the combustion space. By means of the invention, an apparatus is to be provided for purifying waste gases, which can be manufactured cost-effectively and by means of which the disadvantages of the state of the art are avoided. The invention is characterized in that the burner (12) is fastened centrally in the cover (5), the burner (12) has combustion gas nozzles (13) and at least one waste gas nozzle (14), which are directed vertically downwards into the combustion space (6), and that the reaction products, formed during the combustion process, are passed along the inside of the outer pipe (1) into the scrubbing space (7).
