    • PROBLEM TO BE SOLVED: To provide a fluidized-bed apparatus in which tilted partition plates are used and which is hardly clogged by powder to be supplied as a raw material even when the size of the fluidized-bed apparatus is made larger.
      SOLUTION: The tilted-rack fluidized-bed apparatus is provided with: a first tilted rack which is tilted downward from one base end part on the inner wall surface of a vertically-arranged tower toward the vertical central axis of the tower and the tip of which is extended to the position exceeding the vertical central axis; a second tilted rack which is tilted downward from the other base end part on the inner wall surface of the tower toward the vertical central axis of the tower, the tip of which is extended to the position exceeding the vertical central axis and which is arranged so that the first tilted racks and the second tilted racks are arranged alternately and apart; and one or more accumulation preventing plates arranged between a first straight line, which is formed by vertically connecting the tips of the first tilted racks to one another, and a second straight line, which is formed by vertically connecting the tips of the second tilted racks to one another, for preventing raw material powder to be fluidized and scattered from being accumulated on the uppermost surfaces of the first tilted trays.

    • 要解决的问题:即使流化床装置的尺寸较大,提供一种流化床装置,其中使用倾斜的分隔板,并且几乎不被作为原料供给的粉末堵塞。 解决方案:倾斜架流化床装置设置有:第一倾斜齿条,其从竖直布置的塔的内壁表面上的一个基端部向塔的垂直中心轴向下倾斜, 其尖端延伸到超过垂直中心轴线的位置; 第二倾斜架,其从塔的内壁表面上的另一基端部朝向塔的垂直中心轴线向下倾斜,其尖端延伸到超过垂直中心轴线的位置,并且布置成 第一倾斜架和第二倾斜架互相交替排列; 以及一个或多个堆积防止板,其布置在通过将第一倾斜齿条的顶端彼此垂直连接而形成的第一直线和第二直线之间,所述第二直线通过垂直连接第二倾斜齿条 彼此之间,用于防止原料粉末被流化和散射而积聚在第一倾斜盘的最上表面上。 版权所有(C)2009,JPO&INPIT
