Apparatus for contacting solids in the form of freeflowing lumps with liquids or gases

摘要

The invention is directed to an apparatus for contacting in a reactor solids in the form of free-flowing lumps with liquids or for contacting solids with liquids and gases by bringing the reactants into contact with each other, said reactor comprising a housing containing a screen in the area of which contacting takes place whereinP Pthe screen is a rotary screen drum 5,PPthe screen drum 5 rotates in a bottom vat during the operation, said vat holding a gaseous or liquid medium reacting with the solids, andPP the bottom vat 10 can be lowered such that the solids in the screen drum 5 and the medium in the bottom vat 10 can be separated from each other whenever it is desired to alter or interrupt the chemical reaction or physical process.
