る流動層分散装置。 A dispersion plate with a large number of ventilation holes is provided at the bottom of the fluidized bed vessel that stores the fluidized bed inside, and a dispersion plate nozzle with an orifice hole is attached to each ventilation hole, and the dispersion plate is passed through the dispersion plate nozzle. In a fluidized bed dispersion device that allows gas to flow from below to above, there is a pressure detector that detects the pressure inside each dispersion plate nozzle, and a pulsation range of the pressure inside the nozzle based on the signal from this pressure detector. a pulsation width monitoring means that detects the detected value and issues an abnormal signal when the detected value is smaller than a set value; and a clogging release means that causes gas at a higher pressure than the above gas to flow into each dispersion plate nozzle based on the abnormal signal. A fluidized bed dispersion device characterized by being provided with.
