    • A wet raw material drier comprising fluidized-bed drier (8) for drying a wet raw material, gas supply piping (5) for supplying coke oven emission gas as not only a heat source but also a fluidizing gas to the fluidized-bed drier (8) and dust collector (11) for recovering dust-size particles discharged together with gas from the fluidized-bed drier (8), wherein there is provided binder adding unit (18) equipped with means capable of automatic or manual regulation so that the amount of binder added is a constant ratio to dust-size particles with respect to dust-size particles whose recovery rate by the dust collector (11) is varied in accordance with fluctuations of the drying level of wet raw material caused by fluctuations of the flow rate or temperature of supplied coke oven emission gas. A binder is added by the use of the binder adding unit (18). Thus, even if the amount of dust-size particles discharged together with gas from the fluidized-bed drier (8) and recovered is increased or decreased, any dust dispersal and carbon adhesion onto coke oven wall can be securely prevented.
    • 一种湿式原料干燥机,包括用于干燥湿原料的流化床干燥器(8),用于将焦炉排放气体不仅作为热源而且向流化床干燥器提供流化气体的气体供应管道(5) 8)和用于回收与来自流化床干燥器(8)的气体一起排放的尘埃粒子的集尘器(11),其中提供装有能够自动或手动调节的装置的粘合剂添加单元(18),使得 添加的粘结剂的量相对于尘埃粒子的灰尘粒子的比例恒定,其中集尘器(11)的回收率根据由流动的波动引起的湿原料的干燥程度的波动而变化 供应焦炉排放气体的速率或温度。 通过使用粘合剂添加单元(18)添加粘合剂。 因此,即使与来自流化床干燥器(8)的回收的气体一起排出的粉尘粒子的量增加或减少,也可以可靠地防止灰尘分散和碳附着在焦炉壁上。
