The black reactor be applied in all devices in the carbon black manufacturing processed, particularly production of carbon black is the nucleus equipment of carbon black production device.
Black reactor, in the chemical industry technical field, is that a kind of temperature of reaction is high, heat load intensity is large, one of the reactor of severe reaction conditions.Almost the major progress each time of carbon black production technology all relates to the improvement of carbon black reactor directly or indirectly.
The experimental study of carbon black reactor and to design and develop be to improve carbon black list furnace output and efficiency, raising reactor hot strength, the reaction of strengthening soot formation is ultimate aim.
Common carbon black is the carbon black that adopts oven process to manufacture, and is divided into tyre surface carbon black and carcass carbon black, in the industry the inside, is called again: hard (carbon) black and soft carbon, and oven process tyre surface carbon black manufacture method generally has two kinds.
A kind of is regardless of oil fuel and stock oil, by black reactor, is axially entered.Oil plant part fuel combustion under the effect of process (combustion-supporting) air provides the hot kinetic energy of remainder oil-cracking, generates the mixture of carbon black and flue gas.
