Method and Apparatus for Pressure Difference Control in Multi Fluidized Beds System at High Pressure Condition and Multi Fluidized Beds System including the Apparatus for Pressure Difference Control

摘要

The present invention relates to a high pressure datap fluidized bed system with a differential pressure control device, method, differential pressure control of the high-pressure fluidized bed datap and a differential pressure control device. More specifically, the plurality of cyclones to become fluidizing gas injected in each discharge is provided in a plurality of fluidized-bed and the fluidized bed, each of the discharge portion side of the fluidized solids to a gas, solids in the gas rich in the fluidized bed through a gas discharge pipe and, as datap fluidized bed system is provided between the fluid bed having a loop seal to prevent gas mixing and solid reverse flow between the plurality of the fluid bed, to respond to the differential pressure changes that may occur between the fluidized bed in the process and high pressure to raise the pressure in the differential pressure control device which can, a pressure measurement unit for measuring at least one of the internal pressure of the plurality of the fluid bed in real time; A differential pressure measuring part measuring a differential pressure value between the two fluidized-bed of the plurality of the fluid bed in real time; And a pressure control valve which is provided to each of the gas discharge pipe, adjusting the fluid bed pressure based on the value measured by the pressure measuring unit or control the fluid bed pressure based on the differential pressure value measured by the differential pressure measuring part relates to a high-pressure control of a differential pressure datap fluid bed apparatus is characterized in that.;
