    1414007 Agitating powders CESKOSLOVENSKA AKADEMIE VED 27 June 1973 [27 June 1972] 30611/73 Heading B1C A rotatable gas nozzle for fluidizing powders has at least one gas inlet with a nozzle making an angle α to the plane of rotation of the nozzle opening which is in the range 0‹ to +60‹ and an angle # with the radius in the plane of rotation which has any effective positive or negative angle. Preferably α lies in the range 0 to +45‹ and # in the range 0 to +90‹. As shown there are two gas inlets with respective nozzles 6, 6' at different distances from the axis of rotation. Another embodiment (see Figs. 3 and 4, not shown) has a horizontal nozzle with agitating vanes (7, 7') attached to the nozzle head.

    (54) APPARATUS FOR CARRYING OUT PROCESSES IN A PSE-DRIED LAYER
    .7
    It is advisable to choose a large gas flow rate from the nozzles to obtain high kinetic energy that can penetrate long distances. At the same time the number of nozzles with nozzles can be reduced. Making the ends of the tubular tips at an angle in the direction of rotation of the shaft and the bottom makes it possible to use the rotational energy to increase the radial distance of gas penetration into the layer, as a result of which the total number of nozzles can be further reduced. According to experience, with a sufficient gas pressure, one or more nozzles are required to completely fill a 500 mm vessel with a diameter of 500 mm with gas (for complete carbonation) and two to three nozzles for a 1000 mm vessel. If the gas pressure is not large enough, the number of nozzles must be increased.
    It is necessary that the gas flow emanating from the nozzle of the longest nozzle penetrates the walls 1 and the vessel, which prevents the formation of arches. In case of their occurrence, the resulting arch has no support and falls to the level of rotating nozzles, where the gas flow is destroyed.
    A further improvement is that there are two or more gas supply channels along the axis of the rotating body, each channel has its own gas supply and only one nasaoka with a nozzle is connected to each channel, which guarantees that no nozzle contamination and supplying the required gas in a separate nozzle can control the circulating force in the fluidized bed.
    A typical example of the use of the present invention is the direct synthesis of methyl or phenylchlorosipano from powdered silicon and methyl chloride or chlorobenzene.
    FIG. 1 shows the proposed; apparatus, general view; in fig. 2 shows the node T in FIG. If in FIG. 3 - gas distribution device with one radial nozzle; in fig. 4 - the same, top view. The device includes a body made of four tsars 1, piecher44
    Tel 2 with gas-gas nozzle 3 n bottom 4. Inside the case there is a gas distribution device 5 installed by the engine 6.
    The gas distribution device consists of a shaft-7 installed in the upper 8 and lower 9 pin with two parallel channels 10 and 11, which leave the shaft from the side through a system of glands.
    On the shaft 7 in the housing above the bottom, the mixing blades 12 and the radial tubular nozzles 13 with the nozzles 14 are fastened.
    Nozzles have different lengths, and their ends have a deviation by 30 from the radial direction to the bottom of the vessel and 45 from the radius of the shaft in the direction of rotation.
    Fluidizing gas is introduced by one
    or several tubes 15, depending on the number of channels, which i contain shaft 7.
