ABSTRACT:
A provision of the disclosed grating composed of closed loops of plurality of parallelly-arranged straps with clearances between adjacent straps is made to encompass a space of a body of a revolution defined by a vane-type impeller. It proves to be effective for improving gas-absorption by a better gas-liquid contact in a chemical process or fermentation process.
