Closed frequency-adjustable resonant microwave reaction chamber

Abstract

A closed frequency-adjustable resonant microwave reaction chamber belongs to the technical field of microwave energy application. The reaction chamber comprises an outer conductor (1), an inner conductor (2), a closing cap (3), and a coaxial feed (4); the outer conductor (1) is a cylinder metal chamber, and the inner conductor (2) passes through a bottom hole (11) and electrically contacts the outer conductor (1); the closing cap (3) electrically contacts the outer conductor (1) through a screw thread; the coaxial feed (4) passes through a feed hole (32) to allow the closing cap (3) to electrically contacts a coaxial feed outer conductor (42). The invention is manufactured by using a TM010 cylinder resonant cavity principle, realizes frequency reconstructible work within a wide scope, and has a continuous and non-blind area frequency adjusting mode; the invention has the characteristic of simple structure, is applicable to research and application demand for broadband microwave reactions, and has application value on accurate recognition of the effect of frequency on microwave reactions and related process guidance.

Description

technical background [0001] The invention belongs to the technical field of microwave energy application, in particular to a resonant microwave reaction cavity with reconfigurable frequency. Background technique [0002] At present, high-power microwaves have been widely used in heating, medical treatment, drying, coating, environmental protection, auxiliary extraction and other occasions, and achieved better results. In order to understand the basic principles of microwave energy application and microwave chemical reaction, researchers need to use microwave reaction devices to study the reaction mechanism of a small amount of samples under different conditions, and finally guide large-scale industrial applications. [0003] With the deepening of research and application, it is found that microwave frequency is very important to the reaction effect. For example, the microwave absorption of a certain sample is related to the microwave frequency, that is, at a certain freque...

AI Technical Summary

Problems solved by technology

[0007] (3) In order to achieve relevant reaction conditions under limited input power, the existing microwave reaction chamber is usually realized by resonance, and resonance also means that it can only work at a specific frequency

To sum up, the existing resonant reaction chamber can only work normally at one frequency, which cannot meet the requirement of reconfigurable frequency. It can only cover several discrete operating frequencies through multiple reaction chambers of different sizes, which is expensive and inconvenient to use.
