  • Filterless industrial vacuum cleaner operated by compressed gas and suitable for connection to an existing suction and filtering system
    Patent number: 5867865
    Abstract: A device for extraction of vacuum-cleaned material comprising a propellant ozzle (1) operated by propellant gas that has on a suction side a vacuum tube (4) with vacuum tool (20) on the end for extraction of vacuum cleaned material and on a discharge side is connected to an extraction pipe (9) leading to a suction and filtering system, wherein means (5,6) to automatically trigger a function switching on said propellant nozzle (1) when said vacuum tool (20) is removed from its rest position and that automatically trigger a function switching off said propellant nozzle (1) when said vacuum tool (20) is inserted in its res position into a mounting (7) into which a plunger (6) of a valve (5) controlling the propellant gas slidably projects.

  • Process and apparatus for controlled thermal afterburning of a process exhaust gas containing oxidizable substances
    Patent number: 4983362
    Abstract: A process and an apparatus for the thermal incineration of oxidizable substances in a process gas are proposed, whereby the process gas is conveyed through an afterburning apparatus (10) comprising, inter alia, a combustion chamber (18) chamber and a process gas outlet (24) in order to remove purified exhaust gas from the process gas outlet (24), and to mix said purified gas in which the process gas in order to maintain a constant concentration of the process gas.

  • Apparatus for the combustion of oxidizable substances suspended in a carrier gas
    Patent number: 4850857
    Abstract: An appliance for the combustion of oxidizable substances in a carrier gas is described, in which the carrier gas is fed through heat exchanger tubes having inlet ends which are bent outwardly adjacent an outlet for gas from which oxidizable substances have been removed by combustion. Prior to entering the tubes the carrier gas passes an annular chamber in which it becomes pre-heated and condensates are evaporated.
