PURPOSE: A device for preventing reverse flow of corrosive gas in a centrifugal dehydrator is provided to prolong the lifetime of the centrifugal dehydrator by preventing corrosion of internal parts such as a bearing, a screw, and a screw axis. CONSTITUTION: A reverse flow of corrosive gas preventing device of a centrifugal dehydrator comprises: a supernatant inflow chamber(11); a supernatant evacuated chamber(12); a closure(10) in which the partition wall(13) having a discharge hole(13a) communicating the supernatant inflow chamber and supernatant evacuated chamber; an evacuation pipeline(20) being combined in the discharge hole of the partition wall, and discharges the supernatant flowing in into the supernatant inflow chamber to the supernatant evacuated chamber; and a corrosive gas reverse flow preventing plate(30). The corrosive gas reverse flow preventing plate is made of elastic material, connected to one end of the evacuation pipeline, and is fixed on the partition wall. |
