Definitions
- FIG. 9 is a top view of the embodiment of FIG. 8.
- the particles in the fluidized bed will move down into the interior of the passageway 42 in the direction of arrows 46.
- the flow of the gaseous medium such as air entering the restricted opening 43 contacts the particles moving downward through the passageway 42 and causes these particles to be forced upward in a direction indicated by the arrows 47.
- the included angle of the cone is substantially small as illustrated in FIG. 4, the gaseous medium entering the restricted orifice 43 moves along the surfaces of the passageway 42 in the direction of the arrows 48.
- material entering the cone will move down through the center of the cone as indicated by the arrows 46 until it is contacted by the flow of the gaseous medium which is passing in the opposite direction.
- the device could be used as a means of cleaning a gaseous medium such as air prior to being released to the atmosphere or used in subsequent operations.
