Process for charging materiels or mixtures of materiels into pressure vessels and apparatus for carrying out the process

摘要

Masses consisting of solid particles, no longer readily pumpable suspensions, pasty or viscous masses, melts and the like, which may be mixed with a suspending agent, binder or solid or liquid lubricant and which are to be introduced into pressurised reaction spaces, are compacted by means of a conveyor screw rotating in a tightly fitting housing to give a gas-tight mass plug. …??In order to prevent an escape of gaseous reactants or reaction products from the reaction space in the forward direction during starting up and shutting down or in the event of a breakdown, the mass plug is transferred into the pressurised reaction space by means of a discharge head with a solids nozzle and at least one shut-off device, a shut-off piston, for example, being arranged rotatably or displaceably in a housing recessed in the discharge head in such a way that the passage orifice in the shut-off position no longer has a connection to the passage channel between the discharge head and the reaction space. …??Examples of applications are the introduction of flammable substances into a pneumatic gasification reactor or the introduction of substances containing carbon chains for hydrogenation into a hydrogenation reactor. …IMAGE…
