Embodiment 2

[0020] Embodiment 2, compared with Embodiment 1, differs in that the installation method of the blades 5 is different, that is, a support shaft 9 is arranged on the shaft center of the air intake duct 10, and one end of the support shaft 9 is fixedly connected to the inlet. On the air duct 10, the blade 5 is sleeved on the support shaft 9 through the through hole provided in the middle.

Abstract

The invention discloses a device for processing carbon black waste gas. The device comprises a processing chamber, wherein the side wall (close to the bottom) of the processing chamber is provided with a gas inlet pipeline, the upper end of the processing chamber is provided with a gas outlet pipeline, and the upper end of the processing chamber is also provided with spraying devices. The device is characterized in that rotatable blades are arranged in the gas inlet pipeline; and the blades are driven by the carbon black waste gas to be in axial autorotation along an axis of the gas inlet pipeline. With the adoption of the device, calcium sulfate (CaSO4) or calcium sulfite (CaSO3) generated in a pressing of neutralizing sulfur dioxide can be thrown to be far away from the end part of the gas inlet pipeline by centrifugal action so as to avoid the crystallographic calcium sulfate (CaSO4) or the calcium sulfite (CaSO3) to block the gas inlet pipeline.

Description

technical field [0001] The present invention relates to a kind of carbon black preparation, specifically, the present invention relates to a kind of carbon black classifying device. Background technique [0002] Carbon black is a light, loose and very fine black powder whose main component is amorphous carbon. It has a very large specific surface area, ranging from 10-3000m2 / g. Products obtained by incomplete combustion or thermal decomposition under certain conditions (with greater adhesion). Carbon black has a wide range of applications. It can be used as a black dye to make Chinese ink, printing ink, paint, etc. It is also used as a reinforcing agent for rubber and plays an important role in the industrial field. [0003] Traditionally, in the carbon black production process, air and fuel are burned in a reactor, and the raw materials are sprayed into the burning flame after being atomized, and carbon black is generated by high-temperature pyrolysis. Carbon black is sus...
