<p>PURPOSE: To detect and inform the stopping of the rotation of a catalyst unit. CONSTITUTION: A fan unit 21 is arranged in an outer box 10 and the air in a storehouse is discharged into a draft chamber 30. The draft chamber 30 is divided with a partition plank 32 into an ethylene removal zone and the regeneration zone, and a catalyst unit 40 is freely rotatably set so that it may cover an opening 31 formed on the side wall. Every time when the catalyst unit 40 makes one rotation, a roration-detecting switch is actuated. When the rotation stops, a timer switch actuates because there is no signal from the rotation- detecting switch and a lamp is switched on to inform the abnormal rotation.</p> |
