Abstract
A rotary tube reactor, having at least one treatment line composed of tubes whose individual sections have gas chambers which are sealed from each other and wherein each section has a gas outlet and adjacent sections are joined together by material passages, is used for thermal treatment. In accordance with the invention, the reactor is used for the thermal treatment of carbon containing materials, the production of activated carbon, the activation of zeolite granules, the production of pyrophorous metals in the form of powder to lumpy solid materials and substances in liquid form with the evolution of gas.
Claims8
In a rotary tube reactor for the thermal treatment of material in the form of powdered to lumpy solid material and/or substances in the form of liquid, with evolution of gases and optionally the supply of other substances, having a bundle of axially parallel tubes which are mounted in plates arranged perpendicularly thereto, wherein the individual tubes are joined together to form at least one treatment line whose beginning is provided with material supply means and whose end is supplied with a material outlet, the improvement wherein:
- the treatment line includes means dividing same into individual sections forming gas chambers which are sealed from each other and capable of being maintained at different pressures relative to each other, wherein each section has at least one conveying element rotatable therewith to convey material through the section, a gas outlet and adjacent sections are joined together by material passages.
