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 an apparatus for measuring a differential pressure of a high-temperature high-pressure fluidized bed system, a method of installing the same and a method of operating the differential pressure measuring apparatus. And more particularly, to a method of measuring a pressure of a fluid in a fluidized bed reactor, which comprises a lower pressure probe for measuring a pressure at a position where the pressure is installed and installed in a solid layer on the upper side of a gas dispersion plate of a fluidized bed reactor, A differential pressure measuring device for measuring a differential pressure between a first pressure value measured at the lower pressure probe and a second pressure value measured at the upper pressure probe, the differential pressure measuring device comprising: A lower pipe connected to the lower pressure probe and having a second end connected to the differential pressure meter; An upper pipe connected at one end to the upper pressure probe and at the other end to the differential pressure gauge; A connection pipe connected between one side of the lower end pipe and one end of the upper pipe; A first valve disposed on one side of the connection pipe, a second valve disposed on a side of the lower pipe, and a third valve disposed on a side of the upper pipe. .
