Propulsion system and propulsion method based on plasmonic graphite rod electrode

Abstract

The invention discloses a propulsion system based on plasma graphite rod electrodes. The propulsion system based on the plasma graphite rod electrodes comprises a PLC system, an anode component, a cathode component, a support pushing mechanism and a rectifying power supply system. The anode component is graphite rods connected with the positive pole of the rectifying power supply system, and the cathode component is graphite rods connected with the negative pole of the rectifying power supply system. The support pushing mechanism is controlled to stretch and retract through the PLC system, sothat touching and pulling-apart of the anode component and the cathode component are realized, and arc drawing of plasma arcs between the graphite rod electrodes is realized. According to the propulsion system based on the plasma graphite rod electrodes, automatic arc forming of the plasma arcs is realized, precision adjustment is automatically carried out through a PLC program in the arc drawingprocess, the replacement period is long, the replacement is convenient, errors caused by the metal electrode replacement process can be effectively avoided, a lot of manpower, material resources and financial resources are saved, and efficient, fast and accurate plasma arc formation is achieved.

Description

technical field [0001] The invention relates to a propulsion system and a propulsion method based on a plasma graphite rod electrode, and belongs to the field of plasma ignition control. Background technique [0002] In my country's energy structure, there is a shortage of oil resources, and a large amount of oil needs to be imported every year. With the global energy shortage, the price of crude oil is also rising. The ignition and stable combustion of large industrial pulverized coal boilers are traditionally achieved by burning heavy oil, so the oil used for boiler start-up and low-load combustion support has become an important part of the cost of thermal power generation. In addition, when the boiler is fueled and burned, there is a high possibility of secondary combustion at the tail. At the same time, in order to prevent unburned oil droplets from sticking to the electrodes, the electrostatic precipitator is generally in a disconnected state during the fueling period....

AI Technical Summary

Problems solved by technology

The disassembly and installation of metal electrodes is very complicated, because manual replacement cannot guarantee the relative accuracy, and manual accuracy adjustment is required, so it is easy to cause errors

[0013] (3) The disassembled metal electrodes can only be thrown away and have no recyclable value, and the long-term stacking of replaced metal electrodes will also have a certain impact on the environment
