Abstract

The invention provides a plasma fluidized bed powder processing device, which comprises a vertically arranged variable-diameter fluidized bed body, a microwave generator, a rectangular waveguide witha circular hole, a gas feeding system and a cyclone separator, wherein the variable-diameter fluidized bed body is composed of at least two circular tubes with different inner diameters; microwaves generated by a microwave magnetron enter the variable-diameter fluidized bed body through the coupling of the rectangular waveguide and generate plasmas in the bed body; the gas feeding system adds a single or mixed gas to the orifice of the variable-diameter fluidized bed body; and the cyclone separator is used for recycling the powder for re-circulation. The gas outlet on top of the variable-diameter fluidized bed body is connected with gas inlets of a vacuum gauge, an exhaust valve and the cyclone separator via a four-way pipe, and the gas outlet of the cyclone separator is connected to a vacuum pump through an angle valve and an accurate control valve which are connected in parallel; and the power outlet of the cyclone separator is communicated with the side surface of the variable-diameter fluidized bed body through a circulating guide pipe. The bottom circular pipe and the gas inlet of the variable-diameter fluidized bed body are provided with a gas distributor therebetween so as to enable the gas flow to be uniformly distributed and carry the powder.

Description

technical field [0001] The invention relates to the technical field of powder processing, in particular to a plasma fluidized bed powder processing device. Background technique [0002] Surface modification of inorganic powder materials can significantly improve the dispersion, stability, enhancement, electricity, heat, optics, and catalysis of powder materials by adjusting the electrical conductivity, thermal conductivity, refractive index, wettability, hardness, and chemical activity of the surface. and other properties, expanding its application range. [0003] Due to the characteristics of high heat and mass transfer efficiency and uniform treatment, fluidized bed technology has been widely used for powder treatment. By generating free radicals of gas molecules through discharge, plasma technology can greatly improve the reactivity of gases, and is an efficient surface treatment technology. Combining the characteristics of the two to develop a powder processing device ...
