Installation and Operation Method of Differential Pressure Measurement Apparatus in a High Temperature and High Pressure Fluidized Bed System

摘要

The present invention relates to a differential pressure measuring device for a high temperature and high pressure fluidized bed system, an installation method for a differential pressure fluidized bed system, and an operation method for the same. Specifically, a high temperature and high pressure fluidized bed system includes: a lower pressure probe installed in a solid layer in the upper part of a gas dispersion plate of a fluidized bed reactor and measuring the pressure of an installation position; an upper pressure probe installed in an upper end of the fluidized bed reactor and measuring an inner pressure of the fluidized bed reactor; and a differential pressure measuring unit measuring the differential pressure between the first pressure value measured by the lower pressure probe and the second pressure value measured by the upper pressure probe. The differential pressure measuring device for a high temperature and high pressure fluidized bed system includes: a lower pipe whose one end is connected to the lower pressure probe and the other end is connected to the differential pressure measuring unit; an upper pipe whose one end is connected to the upper pressure probe and the other end is connected to the differential pressure measuring unit; a connection pipe connected between one side of the lower pipe and one side of the upper pipe; a first valve installed on one side of the connection pipe; a second valve installed on one side of the lower pipe; and a third valve installed on one side of the upper pipe.
