Bunsen burner type low-temperature plasma auxiliary burning device

Abstract

The invention relates to a Bunsen burner type low-temperature plasma auxiliary burning device. The Bunsen burner type low-temperature plasma auxiliary burning device comprises a base, a gas buffer unit and a plasma reaction unit, wherein the gas buffer unit comprises a fixed flange and a fixed rod; the plasma reaction unit comprises an outer electrode, an inner electrode and a quartz glass tube; the bottom of the fixed flange is fixed to the center of a bottom plate, a gas collection chamber and a stepped hole which are communicated are formed in the center of the fixed flange from bottom to top, and an air inlet which communicates with the gas collection chamber is formed in the side wall of the fixed flange; the bottom of the quartz glass tube is fixed to the stepped hole, and the top of the quartz glass tube protrudes to the outside of the fixed flange; the bottom of the fixed rod is fixed to the center of the bottom plate, and a flange cap sleeve is installed on the quartz glass tube and is connected to the top of the fixed flange; and the bottom of the inner electrode is fixed to the top of the fixed rod, and the outer electrode sleeves the quartz glass tube which is opposite to the inner electrode. The Bunsen burner type low-temperature plasma auxiliary burning device can be removed to replace and has the advantage of convenience in use and later maintenance. Low-temperature plasma which is generated by discharge is rich in various active particles, and an obvious strengthening effect is achieved on burning.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of low-temperature plasma application, and in particular relates to a Bunsen burner type low-temperature plasma auxiliary combustion device. [0003] Background technique: [0004] In recent years, with the development of low-temperature plasma technology, the combustion-supporting technology based on low-temperature plasma has attracted the attention of scholars at home and abroad. Low-temperature plasma has a large number of active particles, which plays an important role in reducing ignition delay and improving combustion efficiency. Low-temperature plasma combustion-supporting technology has also become one of the hot issues studied by scholars from all over the world. [0005] However, people’s understanding of the combustion-supporting mechanism of low-temperature plasma is still unclear. The effect of non-thermal equilibrium plasma on combustion characteristics is an extremely complex physical ...

AI Technical Summary

Problems solved by technology

The plasma area generated by general devices is small, and the plasma with higher energy often faces the problem of high temperature. Therefore, arc discharge is prone to occur in a high-voltage environment, and the microwave source or nanosecond pulse source required by the most cutting-edge devices is also Expensive; (2) Matching of plasma reactor and burner structure

The flat electrode structure that is easy to diagnose is difficult to use as a burner, and the widely used center electrode structure faces disadvantages such as the center electrode cannot be fixed well and the manufacturing process is complicated.
