Equipment for coproduction of interphase charcoal microspheres through hydrogenation of high-temperature coal tar

Abstract

The invention discloses equipment for coproduction of interphase charcoal microspheres through hydrogenation of high-temperature coal tar. The equipment comprises a furnace body, a primary heater, a material guide pipe, a base plate, four heating pipes, a scraper, a retaining ring, a restoring spring, a motor, a threaded rod, a driving bevel gear, a driven bevel gear and a threaded sleeve, whereinthe material guide pipe is inserted to one side of the top of the furnace body, the primary heater is mounted at a central position of the bottom surface of the furnace body, the base plate is arranged inside the furnace body, the four heating pipes are symmetrically mounted on the bottom surface of the base plate, and the threaded sleeve is rotatably mounted at the top of the furnace body. According to the equipment for coproduction of the interphase charcoal microspheres through hydrogenation of the high-temperature coal tar, through joint heating of the primary heater and the heating pipes, the efficiency and uniformity of heating of materials are increased, the generation of the interphase charcoal microspheres is facilitated, and proceeding of follow-up work is effectively assisted;and due to production by the process, economic benefits of enterprises are increased, industry chains of companies are prolonged, and perfect transformation of energy industries represented by coal tar into a high-quality lithium-ion negative-pole material industry is performed.

Description

technical field [0001] The invention relates to the technical field of mesophase carbon microsphere processing, in particular to equipment for high-temperature coal tar hydrogenation and co-production of mesophase carbon microspheres. Background technique [0002] The high-temperature coal tar hydrogenation technology firstly distills high-temperature coal tar, the light components enter the hydrogenation and cracking section to produce light fuel oil, and the heavy component bitumen is directly sold as a by-product. Coal tar pitch is very versatile and can be used to produce high-end carbon materials. Such as carbon fiber, needle coke, mesocarbon microspheres and mesophase pitch. As a product for direct sale, the price is very low first of all, maintained at less than 4,000 yuan / ton all the year round. For the enterprise, the economic benefit is very low. [0003] Mesophase carbon microspheres are the main raw material of high-end lithium-ion anode materials. They have go...

Problems solved by technology

[0003] Mesophase carbon microspheres are the main raw material of high-end lithium ion anode materials. They have the characteristics of good stability and are ideal raw materials for the production of power batteries. The heating efficiency of the carbon microsphere reactor is low. Therefore, we propose an equipment for high-temperature coal tar hydrogenation and co-production of mesophase carbon microspheres.
