Abstract
A catalyst dumping device (10) for unloading a catalyst (50) inside a reactor (1), in which smashed used catalyst is thrown into a dumping pipe (11) formed of a plurality of pipe member (12) provided to the reactor (1) to unload to outside of the reactor (1) by fall by dead weight. Accordingly, the catalyst can be unloaded only by throwing the catalyst into the dumping pipe (11), thereby improving work efficiency. Furthermore, no special apparatus such as a vacuum apparatus is unnecessary, thereby reducing cost for the special apparatus.
Claims9
A catalyst dumping device for unloading used catalyst from an inside of a reactor, comprising:
- a catalyst dumping-out member extending substantially axially inside the reactor and further extending from the inside to an outside of the reactor, the catalyst dumping-out member including a plurality of pipe members consecutively connected with each other to form an opening and a discharge passage to unload the used catalyst,
- wherein the plurality of pipe members are structured to be detachable during the unloading operation to adjust a level of an opening of the catalyst dumping-out member adjacent to a level of the used catalyst.
