Title:
可燃性及び侵食性のガスを収容する容器に内容物を装てん又は排出する装置及び方法
Document Type and Number:
Japanese Patent JP4873581
Kind Code:
B2
Abstract:
An arrangement for charging or discharging solids to or from a vessel under gas pressure, has an upper flap-valve combination (1), a holding chute (2) provided with a purging system (3) and a lower flap-valve combination (4). An Independent claim is included for charging or discharging solids to or from a vessel under gas pressure, where a pair of upper and lower valve arrangements, enclosing an intermediate solids holding air-lock (2), are operated in sequence. The main features of the process are that: (a) only one of the pairs of upper and lower valve combinations is allowed to be open at any instant, the flap valves (6,9) are interlocked by switches (7,10); (b) the air lock space (2) is purged with inert gas, e.g. nitrogen, between valve operations, to displace either air or reactor atmosphere gases to a receiving system; and (c) the valve closure efficiency is pressure tested between valve operations.
