An ignition intake device for microwave plasma reformer

Abstract

The invention discloses an ignition intake device for a microwave plasma reformer, comprising: a reaction chamber, which is an annular cylinder; a microwave power tube, which goes deep into the inside of the reaction chamber, and the microwave power tube can Emitting microwaves into the reaction chamber; a microwave plasma reaction tube, which is arranged at the center of the reaction chamber; and an ignition intake reflection pin, which communicates with the microwave plasma reaction tube, and the ignition intake reflection pin Discharge can be generated under the action of the microwave electromagnetic field to break down the mixed gas in the microwave plasma reaction tube. The invention integrates the gas inlet and outlet ports of the mixed gas on the reflection pin, completely avoiding the gas pipeline entering and leaving the reaction chamber. The problem derived from the cavity opening machine, the invention also effectively uses the mixed gas to cool the discharge tip of the reflective pin, improving the service life of the reflective pin and the reliability of the entire reaction process.

Description

technical field [0001] The present invention relates to microwave electromagnetic induction technology, in particular to a microwave plasma reformer ignition intake device that uses a reflective pin as an intake port. Background technique [0002] The microwave plasma reformer uses microwaves to excite the mixed gas to generate plasma, and the plasma promotes the reforming reaction of the mixed gas to generate hydrogen-rich gas, which has the advantages of high reaction yield and no catalyst required. When carrying out the reforming reaction, a large electric field strength is first required to break down the mixed gas to generate a small number of initial charges. The initial charges obtain energy in the microwave electric field and continue to ionize the neutral gas. The ionization speed of the neutral gas is greater than the recombination speed of the charge. plasma. Once the mixed gas is successfully ignited to generate plasma, only a low microwave power is needed to ma...

AI Technical Summary

Problems solved by technology

The quartz tube needs to be provided with air inlet and outlet ports on the surface of the reaction chamber body, which requires larger air inlet outlets and exhaust outlets on the reaction chamber body. The cavity wall current has a great influence, which not only increases the design difficulty but also has a great influence on the microwave distribution in the reaction cavity
