PRESSURE CONTROL MECHANISM OF CONTAINER

摘要

PROBLEM TO BE SOLVED: To provide a mechanism capable of well and stably controlling the pressure of a container without generating the errosion or clogging of a control valve. SOLUTION: This pressure control mechanism is constituted so that the pressure in a reactor 12 is regulated by a first pressure control valve 26 provided to an outflow pipe 20 for allowing a fluid containing solid fine particles to flow out of the reactor 12 and the fluid is separated into a liquid component and gaseous component by a gas-liquid separator 28 provided on the downstream side of the pressure control valve 26 and the pressure of the gas-liquid separator is controlled by a second control valve 36 provided to a gas sending-out pipe 30 for sending out the separated gaseous component from the gas-liquid separator 28 and the liquid level of the gas-liquid separator is controlled by liquid level control valve 40 provided to a liquid sending-out pipe 32 for sending out the separated liquid component from the gas-liquid separator 28. A filter 44 for catching solid fine particles in the liquid component is provided to the liquid sending-out pipe 30 on the upstream side of the liquid level control valve 40.
