APPARATUS FOR THERMAL TREATMENT OF CARBON-CONTAINING FIBROUS MATERIALS Russian patent published in 2014 - IPC D01F9/12 D01F9/32 

FIELD: chemistry.

SUBSTANCE: apparatus for thermal treatment of carbon-containing fibrous materials includes a carbonisation device and a graphitation device insulated from the carbonisation device, between which is integrated a device for accumulating and cooling carbonised material and/or washing and drying thereof. The graphitation device can be in the form of two identical electro-graphite furnaces which are not linked with each other and arranged in parallel one over the other. The electro-graphite furnace includes a heating element, a pipe for removing volatile products, a valve at the outlet for preventing entry of gaseous medium into the furnace, pipes for feeding an inert gas, a drive mechanism for transporting the material to be thermally treated, and a cooled metal housing with a heat insulation unit, in which there are horizontal slit-type channels for transporting material. The inlet channel is in the form of a pipe with a rectangular cross-section for removing volatile products, and between its upper and lower inner surfaces over the transported material at an inclination to said surfaces there is a graphite screen with gaps between the upper surface of the channel and the upper end of the screen, and between the lower surface of the channel and the lower end of the screen. The screen divides the heating chamber into a maximum temperature area, having a heater, and a medium temperature area.

EFFECT: high efficiency and stability of the process of thermal treatment of carbon-containing fibrous materials, high quality of the end product.
