A method for producing carbon microspheres and the device used therein

Abstract

The invention discloses a production method for carbon microspheres and a used device thereof, belonging to the technical field of carbon microsphere production. The production method comprises the following steps: subjecting raw-material liquid modified asphalt from a tar workshop section to uniform mixing under stirring, then carrying out heating and pressurizing in a closed space in a constant speed, starting natural cooling and depressurizing, then mixing the liquid modified asphalt and lightweight wash oil so as to form a mixed material, subjecting the mixed material to separation through a centrifuge, and during operation of the centrifuge, allowing mixed oil to be separated from the lower part of the centrifuge; and allowing a carbon microsphere raw material to be separated from the interior of the centrifuge, and subjecting the separated carbon microsphere raw material to drying treatment so as to produce the carbon microspheres. The device provided by the invention comprises a sedimentation tank, wherein two reaction vessels are arranged above the sedimentation tank; each reaction vessel is correspondingly arranged on a weighing measuring unit used for weighing the reaction vessels; the bottom part of each reaction vessel is provided with a pipeline communicating with the sedimentation tank; and each pipeline is provided with a valve. The device provided by the invention has the characteristics of low production cost, high production efficiency, high product quality, safety, environmental protection, etc.

Description

technical field [0001] The invention belongs to the technical field of carbon microsphere production. Background technique [0002] At present, in the traditional production process of carbon microspheres, medium-temperature pitch is used as raw material, and the raw material is single. In the production process, catalysts and diluting toluene auxiliary materials are added, which is not conducive to equipment, but also increases the iron content of the product. The use of toluene reduces the safety factor of the workplace, and the use of metering tanks alone wastes energy consumption and is not conducive to environmental protection. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a production method of carbon microspheres and the device used therein, which have the characteristics of low production cost, high production efficiency, high product quality, safety and environmental protection. [0004] In order to ...
