Problems solved by technology

However, in some applications (such as metal deposition, such as the preparation of high-quality graphene on non-metallic substrates, etc.), the reaction temperature needs to reach 1300°C-2000°C, but due to the material and design of the device, it is difficult to achieve in general fluidized bed devices

Abstract

The invention discloses a high-temperature fluidized bed reaction device, and belongs to the technical field of powder material production. The device comprises a high-temperature heating furnace body, a feeding cabin, an upper sealing flange, a high-temperature-resistance furnace pipe, an airflow regulator, and air distributor, a lower sealing flange and a discharging cabin, wherein the inner cavity of the high-temperature-resistance furnace pipe is served as a fluidized bed reaction cavity; the feeding cabin is connected with the top end of the high-temperature-resistance furnace pipe through the upper sealing flange; the bottom end of the high-temperature-resistance furnace pipe is connected with the discharging cabin through the lower sealing flange; the airflow regulator and the gas distributor are arranged in the high-temperature-resistance furnace pipe. According to the device, power material fluidization can be realized under a high-temperature environment, and the problems ofthe powder layering, hardening and the like of a conventional device in a reaction process due to an uneven atmosphere condition are avoided. Meanwhile, since a controllable feeding cabin and a controllable discharging cabin are designed, continuous material loading and unloading and quick material cooling can be realized, production efficiency is greatly improved, and production cost is lowered.

Description

technical field [0001] The invention relates to the technical field of powder material production, in particular to a high-temperature (1300-2000° C.) fluidized bed reaction device. Background technique [0002] Powder materials are widely used in various fields of production and life, and are a very important type of material. However, for the powder materials prepared in the gas phase environment, if the conventional static gas phase deposition process is used, problems such as delamination and hardening of the powder materials will be caused due to uneven growth atmosphere. [0003] The above-mentioned problems can be avoided by using a fluidized bed device. A fluidized bed device refers to a reaction device that suspends a large number of solid particles in a moving fluid, so that the particles have some apparent characteristics of the fluid. This fluid-solid contact state is called solid fluidization, that is, a fluidized bed. It uses high-speed airflow to drive the ...
