Problems solved by technology

The structure of the middle insertion section of the existing plasma generator is mostly a multi-stage insertion section, and the insulation design is used between the insertion sections and between the insertion section and the cathode and anode. Current arc switching device to realize jumping between arc electrodes
However, the further downstream the arc channel is, the structure of the arc channel flow field changes, and the turbulence increases. The arc length is unstable when the air flow is increased, and an external magnetic field is often required to stabilize the arc. This not only increases the process complexity, but also increases the arc length. Engineering Application Difficulty

Abstract

The invention discloses a plasma generator with a middle section structure, which comprises a front electrode, a middle section, a rear electrode, a main gas inlet cyclone gas ring and an auxiliary gas inlet cyclone gas ring. One end of the front electrode is connected with one end of the auxiliary gas inlet cyclone gas ring, and the other end of the auxiliary gas inlet cyclone gas ring is connected with one end of the middle section; the other end of the middle section is connected with one end of the main air inlet cyclone gas ring, and the other end of the main air inlet cyclone gas ring is connected with one end of the rear electrode. The unique middle section structural design is adopted, the middle section and the front electrode do not need to be insulated, jumping from the middle section of the arc root of the electric arc to the front electrode is achieved through the exquisite design of the middle section structure, the pneumatic organization and the main air inlet and auxiliary air inlet airflow distribution technology, and compared with a multi-stage middle section, the structure is simple, and large voltage and large power can be stably output without adding a large-current arc jump device.

Description

technical field [0001] The invention relates to a plasma generator, in particular to a plasma generator with an intermediate section structure, and belongs to the field of plasma. Background technique [0002] As an optional technical route for hazardous waste treatment, thermal plasma has been paid more and more attention, and its characteristics of high temperature and high energy density are prominent. However, there are no development reports and applications of megawatt-level and above high-power plasma generators in China. The main development difficulties are: the arc current of high-power plasma generators often reaches 600A or even more than 1000A, and the electrode ablation accumulation increases; the arc voltage of megawatt-level plasma generators exceeds 1500V, and the arc stability and arc root motion control are more difficult. [0003] Traditional high-power plasma generators adopt a multi-stage middle section structure design, such as US4543470 SKF plasma ge...
