Self-heating low-voltage arc device for carrying out high-temperature decomposition and gasification on solid material

Abstract

The invention relates to a self-heating low-voltage arc device for carrying out high-temperature decomposition and gasification on a solid material. The device comprises a heating device, a platinum needle, an infrared temperature measurement probe, a gas recovery pipe and a three-way valve, wherein the heating device comprises a pressure resistance shell, a silicon carbide heating rod positioned in the pressure resistance shell and a platinum crucible; the silicon carbide heating rod is connected with an external controller by a wire; the platinum needle is arranged in the pressure resistance shell, is positioned above the platinum crucible to serve as an arc initiating electrode and is connected with the external controller by a wire; the infrared temperature measurement probe is arranged at the top of the inner surface of the pressure resistance shell and is connected with the external controller by a wire; one end of the gas recovery pipe is arranged at the top of the inner surface of the pressure resistance shell, and the other end of the gas recovery pipe is connected with an analysis device; and an opening of one end of the three-way valve is formed at the lower part of the pressure resistance shell; the second end of the three-way valve is connected with a vacuum pump; and the third end of the three-way valve is connected with a gas carrier pipeline. Compared with the prior art, the device implements the gas state analysis on the solid material and solves the problems of large dead volume, low gasification efficiency, fussy operation and environmental pollution of an existing solid gasification device by the compact system structure design.

Description

technical field [0001] The invention relates to a self-heating low-voltage arc device for high-temperature decomposition and gasification of solid materials. Background technique [0002] With the continuous development of our country's social economy and the improvement of people's living standards, social production has higher and higher quality requirements for various industrial products, especially for bulk industrial raw materials and finished products such as steel, non-ferrous metals, and advanced ceramics. For products, accurate and quantitative detection of its composition or content has become an important means of supervising its production. [0003] In the detection process of solid samples, the extraction process of effective components is particularly critical. At present, for solid samples with relatively high melting points, direct heating high-temperature gasification method or direct high-voltage arc gasification method are often used to obtain the compon...
