INSTALLATION FOR CALCIUM CARBIDE OBTAINING Russian patent published in 2014 - IPC C01B31/32 C01F11/00 

FIELD: chemistry.

SUBSTANCE: installation for obtaining calcium carbide includes reactor with case in form of hermetic cylindrical vertical reservoir, upper end of which is equipped with loading channel, coaxial with it (3). Bottom part (2) of case is made conical and is equipped with outlet jet (12). Upper end of loading channel (3) is equipped with hermetic lid, on which placed is plasmatron (18), which forms plasma cord (21), directed downwards into the space between edges (22) of pouring platforms (7). Cavity of loading channel (3) is connected with sources of carbon dioxide (6) and sources of raw material mixture (4), which is connected with coal source (15) and limestone (16). Coal source (15) is connected with loading channel (3) by additional channel of coal supply (29). Upper (10) and lower (11) electromagnetic coils are installed below the lower edge of feed channel (3) coaxially to reactor case and along it on different height. Upper (10) electromagnetic coil is fastened on the surface of rotary platform (13) and is equipped with drive (14) of its rotation relative to base (27), and lower (11) electromagnetic coil is placed near the bottom part (2) of reactor. Space of upper part (1) of reactor case is connected with gas-separating unit (25), outlets of which are connected respectively with source of carbon dioxide (6) and reactor of carbonic acid synthesis (26) by means of gas-discharging channels (23, 24).

EFFECT: increase of target product output and reduction of power consumption of calcium carbide production.
