Carbon black producing method |
摘要 |
A carbon black producing apparatus is provided in which a quench fluid is introduced into a reaction zone for cooling hot smoke which contains solid carbon black particles which are produced by the pyrolysis of a carbon black make hydrocarbon by the heating of same with a combusted air/fuel mixture. The quench fluid is introduced into the reaction zone in a generally tangential direction and in a direction counterrotational to the direction of the vortex flow of the hot smoke flowing along the length of the reaction zone. The cooled smoke is passed to a heat exchanger for further cooling of the smoke after which the smoke is separated into an off-gas phase and a carbon black particle phase by filtering means. The carbon black can then be pelleted and dried for use.
