Drum-type carbon black ozonation retort

The invention discloses a drum-type carbon black ozonation retort which can perform uniform rolling around a fixed shaft forming a certain included angle with the horizontal direction to facilitate flowing of carbon black. During oxidation of carbon black, granular carbon black flows into a retort body through a material conveying pipe which forms a certain angle with the axial position of the feeding-side end surface of the retort, ozone axially flows into the retort body from the end surface of the same side through a gas conveying pipe of which the tail end is closed, vertically sinks and then is buried at the bottom of the carbon black layer in the horizontal direction of the wall of the retort, the gas conveying pipe, of which the tail end is closed, in the horizontal direction of the wall of the retort is bestrewed with lots of micropores, and on dependence of pressure of an ozone generator, ozone is discharged out from the micropores to be subjected to oxidation reaction with carbon black. After oxidation of carbon black is finished, carbon black flows out from a discharge opening in the bottom of the end surface of the other side while waste gas is discharged out from an exhaust hole in the upper part of the end surface of the same side. The drum-type carbon black ozonation retort is wholly made of stainless steel, realizes a continuous controllable production process, ensures that oxidized carbon black is uniform and stable in quality, and facilitates equipment maintenance and safety production.
