A wire barrel type unipolar charging device for charging solid particles

Abstract

The present invention proposes a wire barrel type monopolar charging device for charging solid particles. The diameter of the stainless steel cylinder of the device is smaller than the diameter of the perforated quartz tube, and the two are coaxially connected through a No. The diameter of the perforated quartz tube is smaller than the diameter of the grounding shell, and the two are connected coaxially through the No. 2 reducing joint; the perforated rubber plug is inserted into the tube wall of the perforated quartz tube, and the quartz sleeve penetrates the perforated rubber plug and inserted into the perforated quartz tube , the metal rod includes a long side and a short side, the long side and the short side are perpendicular to each other in an "L" shape, the long side of the metal rod is located at the axis of the open-hole quartz tube and the grounded shell, and the short side of the metal rod passes through the quartz sleeve upwards Tube. To solve the phenomenon of creepage and local breakdown caused by the failure of insulating materials in the wire drum charging device in the prior art, a wire drum type unipolar charging device for charging solid particles is provided. The insulation between the various parts is guaranteed, and the safety hazard in the experiment process is greatly reduced.

Description

technical field [0001] The invention discloses a wire barrel type monopolar charging device for charging solid particles, which belongs to the technical field of aero-engines. Background technique [0002] Under some specific operating conditions, the aero-engine is in a fuel-rich combustion state, which inevitably produces some soot particles. A large number of soot particles produced by incomplete combustion will be deposited on the surface of the engine nozzle, affecting fuel consumption. If the atomization and combustion effects are severe, the nozzles will be clogged, causing parking accidents in the air. The harm of carbon deposition faults is huge, and the existing carbon deposition suppression methods more or less affect the performance of the engine, and cannot completely eliminate carbon deposition, so how to suppress carbon deposition under the condition of ensuring the normal operation of the engine The occurrence of such failures has become one of the key bottl...
