Problems solved by technology

[0002] At present, in the traditional production process of carbon microspheres, medium temperature asphalt is used as raw material, and the raw material is single
In the production process, catalysts and toluene auxiliary materials for dilution are added, which is not conducive to the equipment, and at the same time 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

Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] see figure 1 In an embodiment, the high-temperature liquid modified asphalt raw material from the tar plant section is transported to a mixing tank for stirring, and after being evenly stirred, it is transported to the reactor through a pipeline. The reactor is pre-heated to about 220° before the raw material liquid is transported. When it reaches about 78% of the reactor, stop feeding to meet the requirements of synchronous boosting of raw materials in the process of heating up in the closed reactor, and at the same time open the stirrer in the reactor to stir the raw materials. h Raise the temperature of the raw material at a uniform speed. When the temperature of the modified asphalt raw material liquid in the reactor is raised to 438°-440°, the pressure is basically maintained between 780kP-800kP; After the constant temper...

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 ...
