DIFFERENTIAL PRESSURE CONTROL APPARATUS OF HIGH-PRESSURE AND MULTI-TIP FLUIDIZED BED, DIFFERENTIAL PRESSURE CONTROL METHOD, AND HIGH-PRESSURE AND MULTI-TIP FLUIDIZED BED SYSTEM INCLUDING SAME

摘要

The present invention relates to a differential pressure control apparatus for high-pressure multi-top fluidized beds, a differential pressure control method, and a high-pressure and multi-top fluidized bed system having the same. More specifically, the multi-top fluidized bed system includes: multiple fluidized beds individually fluidizing solid substances with fluidizing gas injected thereto; multiple cyclone units which are individually arranged on the outlets of the fluidized beds to discharge the gas mixed and floating in the gas and solid substances on the fluidized beds to the outside through gas discharging pipes; and a loop chamber which prevents a reverse flow of the solid substances and mixture of the solid and gas substances between the fluidized beds while being arranged between the fluidized beds. The differential pressure control apparatus dealing with a change in the differential pressure which can be generated between the fluidized beds in a high pressure state and during a pressure raising process includes: a pressure measuring unit measuring the internal pressure of at least one of the fluidized beds on a real-time basis; a differential pressure measurement unit measuring the differential pressure value between two of the fluidized beds on a real-time basis; and a pressure control valve which is arranged on each of the gas discharging pipes, adjusts the pressure of the fluidized beds based on the value measured by the pressure measurement unit, and adjusts the pressure of the fluidized beds based on the differential pressure value measured by the differential pressure measurement unit.;COPYRIGHT KIPO 2017
