In order that the air filter is easier to service and maintain, the compressed air is fed over a ring slot (28) into the exhaust (8) and is blown in the direction of the open outlet (21) for the purpose of creating an ejector effect to keep the exhaust free from dust. Compressed air is blown through the exhaust so that blockages cannot build up there nor in the area of the preliminary filtering stage. Specific, regular supervision of this area therefore becomes necessary.

  • Patent number: 5529591
    Abstract: Catalyst and hydrocarbon vapors are separated in separator-stripper vessel by a reverse flow separator assembly in a top portion of the separator vessel. The separator assembly contains a shrouded eductor where the particles and gas enter the eductor, and upon exit the gas reverses direction to travel through the passage between the eductor and the shroud, thus causing disengagement of the particles. The gas free of particles then passes out the vessel exit and the particles return to the particle bed in the lower portion of the vessel.

  • Patent number: 5482536
    Abstract: An apparatus for containing and scrubbing toxic or corrosive gases from a leaking pipe or cylinder is provided. A gas passageway attaches at one end to a leakage location on a pipe or cylinder, and at the other end to an air operated exhauster. The air operated exhauster, through the input of a non-flammable purge gas, creates an exhaust flow from the leakage location to a drum which is attached to the air operated exhauster. The drum contains a scrubbing media which, when it contacts the leaked gas, cleans or removes the harmful component, thus allowing release to the atmosphere of the cleaned air.

  • Patent number: 4934393
    Abstract: A spray gun cleaning apparatus for containing and collecting toxic materials resulting from cleaning a spray gun with a cleaning fluid is disclosed. The apparatus includes an interior airflow passageway, a receptacle at an inflow end of the passageway for receiving the spray from the spray gun nozzle, and an outlet at the other end of the passageway for discharging airflow into the ambient environment. At least one filter/condenser is located within the passageway for condensing cleaning fluid vapor into liquid which flows into a waste container, preferably by gravity flow.

  • Patent number: 4826514
    Abstract: An apparatus is described for dampening hazardous material. A collector pan is positioned at the end of an elongated conduit with a spray nozzle being positioned within the collector pan. The spray nozzle is in communication with a source of water under pressure or a suitable encapsulating fluid. The elongated conduit is in communication with a cylindrical trap which in turn is in communication with a conventional filtration unit. When the filtration unit is actuated, air is drawn through the collector pan, through the elongated conduit, through the cylindrical trap and into the filtration unit. Actuation of the spray nozzle will cause the fluid to be sprayed onto the material to be removed, compressed or encapsulated with any asbestos material being dislodged during the spraying operation being collected in the collector pan and delivered to the cylindrical trap.

  • Patent number: 4735639
    Abstract: Vacuum loading apparatus is provided for ingesting a mixture of debris (such as particulate matter) and ambient air, for collecting the debris for disposal, and for filtering the ingested air before discharging it to atmosphere. The apparatus comprises three relatively light-weight, portable, independently movable modules, each incorporating a weeled chassis, to facilitate their movement to, from and on the jobsite, whereat they are interconnected for use by large flexible hoses. The power module comprises a motor-driven vacuum blower. The debris-receiver module comprises a receiver tank with a removable disposable debris-collection bag therein (which bag may or may not have an associated filter) and a debris-collection vacuum hose connected to the exterior thereof. The upper and lower ends of the receiver tank and the inside and outside of the bag are exposed to the same negative air pressure in the tank to prevent its collapse or damage by a pressure equalization duct.

  • Patent number: 4725409
    Abstract: An arrangement for fine dust separation in a fluidized bed reactor with a clone and dust return conduit. A venturi tube extends from the solids discharge of the cyclone intermediate the cyclone and the dust return conduit, and a gas injector is located at the inlet of the venturi tube. The fine dust which leaves the fluidized bed is separated from the exhaust gas in the cyclone, and the separated dust is conducted from the cyclone, through the venturi tube and the dust return conduit, and into the lower region of the fluidized bed. Gas is conducted through the gas injector to help force the separated dust through the return conduit and into the fluidized bed.

  • Patent number: 4559067
    Abstract: A Coanda-type airmover 16 is mounted vertically on a hollow base 10 to draw air through the base from filtering means comprising a pre-filter 26 and an absolute (HEPA) filter 28. The airmover discharges the filtered air upwards. The two filters are stacked on the base for air to be drawn downwards through them from an inlet duct 30 leading horizontally from a contaminated-air inlet 32 of the device. An air tight cover 34 can be secured to cover the inlet 32 of the duct when the equipment is not in use, enabling contaminated filters to be left in place during transportation. The portable device may be used for withdrawing and cleaning fibre-laden air from a working space where asbestos stripping is taking place.
