INSTALLATION OF CARBONISATION OF FIBRE VISCOSE MATERIALS FOR OBTAINING COMPOSITE CARBON FILAMENTS Russian patent published in 2014 - IPC D01F9/16 D06C7/00 

FIELD: textiles, paper.

SUBSTANCE: invention relates to chemical technology of fibrous materials and relates to installation of carbonisation of fibre viscose materials for obtaining composite carbon filaments. The installation comprises a housing and a carbonation chamber placed in it, which end walls are provided with slotted holes for input of the source material and output of carbonised material, and sealing closures, as well as electric heating elements, pipe branches for supply of inert gas and output of distilling gases. The housing with the chamber is mounted obliquely at an angle 10-15° to the horizontal plane. The hole for input of the source material is located in the lower end. The chamber is placed into the additional casing, which upper wall is spaced from the upper chamber wall at a distance of 100-150 mm, is provided with a transverse slot that extends the entire width of the upper wall of the chamber and communicates with the pyramidal-shape pipe branch for devolatilisation, integrally mounted near the output end of the housing of the installation, and equipped with heating. Heat insulation of the installation is located between the walls of the housing and the casing, the heaters are located outside the chamber, at that they are in direct contact with the lower wall, and in relation to the upper wall they are fastened with the possible variable clearance.

EFFECT: invention provides improvement of the installation design and improves the quality of the carbonised material produced at this installation.
