VERTICAL CHAMBER KILN FOR HEAT TREATMENT OF DIFFICULTLY CONVERTIBLE CARBON MATERIALS Russian patent published in 1997 - IPC

FIELD: coke industry. SUBSTANCE: invention aims to convert carbon raw materials of the type of crude oil electrode coke into finely structured product. To that end, vapor-gas-withdrawing collectors 6 are provided with dust-settling recesses 15. The latter have material-returning chutes 16, discharge holes 17 of which are disposed on walls of working chambers 2 at preselected distance from cooling agent-delivery nozzles 13. This distance is equal to (0.1- 2.0)H where H is level at which chains of agent-delivery nozzles 13 are disposed and which is measured from plane on which inlet cuts of working chambers 2 is disposed. Solid coke particles leaving disperse system are settled in dust-settling recesses 15 and flow over chutes 16 into working chamber 2. EFFECT: facilitated processing of raw material. 6 dwg
