Apparatus for delivering treating gas to bulk material such as hot coke or coal situated in a container

摘要

An apparatus for treating bulk material such as hot coke or coal by supplying a treating gas thereto includes a container in which the bulk material is situated during treatment thereof. A gas distributor extends into the interior of this container and includes a plurality of coaxial elongated pipes which have open ends in the interior of the container, an elongated bar extending coaxially along the innermost one of said pipes and also having a free end situated in the interior of the container. The ends of the several pipes which are in the container are open and are enlarged while the inner free end of the bar in the container is also enlarged, and a moving structure is operatively connected with at least one of the pipes as well as the bar for axially moving the same relative to each other so as to adjust the positions of the free end of the bar and the open ends of the pipes with respect to each other. The pipes define between themselves passages for treating gas while the bar and the innermost pipe also define between themselves a passage for a treating gas. Thus with the above structure by regulating the axial positions of the pipes and bar with respect to each other it is possible to provide at the open ends of the pipes and by way of the enlarged end of the bar the equivalent of adjustable nozzles through which a treating gas can flow into the interior of the container.
