ABSTRACT:
An arrangement for sealingly closing an opening of a reaction vessel includes a frame member which bounds the opening and a closing member which is movable between a closing position in juxtaposition with, and an opening position at a spacing from the frame member, as well as a sealing arrangement for sealing the gap between these members in the closing position of the closing member. The sealing arrangement includes an inner seal and an outer seal which define a sealing space filled with a preferably inert gaseous medium. The outer seal includes two sealing elements which extend across the gap in the closing position and define between themselves a confining space, and a liquid seal confined in this confining space. At the upper region, the liquid seal may be confined in an upwardly open horizontal channel and at the lower region it may be contained in a trough-shaped receptacle. The sealing liquid of the liquid seal is preferably circulated through the confining space to act as a cooling medium.
