摘要： An apparatus and process is disclosed for the separation of solids from gases in a mixture which is most particularly applicable to an FCC apparatus. The mixture of solids and gases are passed through a conduit and exit through a swirl arm that imparts a swirl motion having a first annular direction to centripetally separate the heavier solids from the lighter gases. The mixture then enters a gas recovery conduit in which at least one plate radially extending from an inner wall impedes rotational motion of the mixture. The mixture enters cyclones at the other end of the gas recovery conduit without substantial swirling motion.

摘要： Granular ore or ore concentrate is charged into a furnace for calcining the ore at temperatures of 400 to 1050° C., the ore forming a stationary fluidized bed in the furnace. The ore is thrown onto the fluidized bed through an opening in the furnace housing disposed above the fluidized bed, the ore being accelerated by blades of a rotating impeller. The impeller is disposed outside the furnace in the vicinity of the opening of the housing. Preferably, the rotational speed of the impeller is variable, and the impeller is movable and/or pivotable with respect to the furnace.

摘要： Two spaces are provided, one of which is at a higher pressure than the other. A transfer arrangement serves for transferring a finely divided solid material, e.g., a combustible fuel, from one to the other space, usually from the lower-pressure space into the higher-pressure space. This arrangement includes a housing bounding a spherical chamber having two openings each of which communicates with one of the spaces. A spherical body is located turnably in the housing and provided with a blind bore the open end of which can be placed into communication with one or the other of the openings, depending upon the turning of the spherical body. A piston is reciprocable in this bore and can be retracted to draw a quantity of solid material into the blind bore when the open end thereof registers with one of the openings, and can be advanced for expelling the quantity when the open end registers with the other of the openings. A direct communication between the two spaces is therefore reliably avoided at all times.
摘要翻译：提供了两个空间，其中一个位于比另一个更高的压力下。传送装置用于将细分散的固体材料（例如可燃燃料）从一个空间传送到另一个空间，通常从低压空间传送到高压空间。这种布置包括限定具有两个开口的球形室的壳体，每个开口与空间中的一个连通。球形体可转动地定位在壳体中并且设置有盲孔，其盲孔可以根据球体的转动而被放置成与一个或另一个开口连通。活塞在该孔中是往复运动的，并且当其开口端与其中一个开口配准时，可以缩回以将一定数量的固体材料吸入盲孔中，并且当开放端与另一个开口端注册时，活塞可以前进以排出量的开口。因此，在任何时候都可靠地避免两个空间之间的直接通信。

摘要： A fluidized-bed system in which a main chamber and an auxiliary chamber communicate with each other through an opening in a common wall near the bottom of the main chamber. An endless traveling grate rises along the bottom of the main chamber and through the opening into the auxiliary chamber. Granular material is fed to the main chamber and fluidized to a first level by gas passing through apertures in the grate. The fluidized material flows through the common wall into the auxiliary chamber and is held to a lower second level there by a gas pressure higher than that in the disengaging space in the main chamber. The conveyor rises beyond the top of the bed in the auxiliary chamber and discharges lifted material from the auxiliary chamber into a water seal.
