Experimental method and apparatus for evaluation of jet nozzle, venturi, bag-cage performance in pulse-jet filtration and dust collecting system

摘要

The present invention relates to an experimental method and apparatus for measuring the performance of a jet nozzle, a venturi, and a bag-cage in a pulse-jet type filtration and dust collecting system by measuring a pressure distribution or a maximum pressure distribution in a filter cloth, It is designed to easily disassemble and assemble test nozzles, venturi, and back-cage with the whole system. Also equipped with pressure sensor, analog-digital conversion card and computer to measure minute pressure in filter cloth. It enables accurate evaluation of the performance of the injection nozzle, venturi, and back-cage in a short period of time.
