REVERSE CURRENT AND BAFFLE COLUMN FLOATING MATTER DIVIDING DEVICE FOR DIVIDING MINERALS AND UNBURNED CARBON IN COAL LIME

摘要

PURPOSE: A reverse current and a baffle column dividing device is provided to produce a good quality of coal by efficiently dividing and to improve the recycling rate of the coal lime. CONSTITUTION: A reverse current and a baffle column dividing device is composed of: a mineral recollecting tub(9) on the lower side and an unburned carbon recollecting tub(10) on the upper side; a reverse current baffle column(1) supplied the compressed air from the ejector of an aeration system; an aeration system(20 for generating a fine bubble by mixing the coal lime slurry absorbed from a centrifugal pump(8) with the compressed air; a pressure regulation device(7) and a flow meter(6) for mixing the compressed air flowed in from a venturi tube(5) with the mineral liquid absorbed from the column with a right pressure in a right amount; a conditioning tank(11) for coating a water holding agent on the particle surface of the hydrophobic unburned carbon by mixing and agitating a foaming agent and a water holding agent in the cola lime in a slurry state.
