POWDERY SOLID BODY CONVEYANCE APPARATUS

摘要

PROBLEM TO BE SOLVED: To effectively convey a powdery solid body such as char to a part at a high pressure without using a lock hopper system and reduce the cost in a powdery solid body conveyance apparatus. SOLUTION: An inflow port 43 for the powdery solid body and the char is provided on a central part of an upper part of the cylindrical suction type powdery solid body conveyance apparatus 34. One or two outlet pipes 42 for discharging the powdery solid body and a conveyance gas are arranged along the conveyance apparatus outer wall tangential line direction. Conveyance gas supply pipes 36 and 38 for rotating the powdery solid body and the conveyance gas are arranged in the tangential line direction with respect to the conveyance apparatus outer wall in front of a setting part of the outlet pipe 42. The powdery solid body is rotated by a high speed jet stream 44c from the supply pipe in the conveyance apparatus 34, and thereby the powdery solid body is forcibly rotated and sucked from the inflow port 43. Therefore, a large pressure difference from the outlet pipe 42 is generated and stable and continuous supply without a counterflow can be performed. Thus, performance equal to or more than an ejector system can be achieved.
