DEVICE AND INSTALLATION FOR INJECTING PARTICULATE MATERIALS INTO A CHAMBER, AND CORRESPONDING METHOD

摘要

The invention relates to a device and an installation for injecting materials, especially particulate materials, into a chamber, and to the corresponding method. The inventive device for injecting materials into a reaction chamber during the course of a pressurised water treatment method has a pressurisation capacity (24) with an internal volume in which a mobile arrangement (29), for example bellows, is mounted, said arrangement dividing the device into two variable volumes in a sealed manner, that is a pressurisation capacity (32) and a hydraulic pressurising capacity (34). The variable hydraulic pressurising capacity of the inventive device is connected to the outlet (15) of the aqueous phase of a liquid/gas separator (14) which separates the liquid and gaseous phases from an effluent leaving the reaction chamber (2).
