Oxygen flame composite plasma torch

Abstract

The invention discloses an oxygen flame composite plasma torch. A mounting frame is equipped with a first mounting flange and a second mounting flange; a through hole extending from the first mountingflange to the second mounting flange is formed in the middle of the mounting frame; an air intake passage is formed in an air intake pipe; the air intake end of the air intake passage is located on the side of the first mounting flange away from the second mounting flange, and the air outlet passes through the mounting flange and extends out of one side of the second mounting flange; and an electrode assembly is located on one side of the second mounting flange far from the first mounting flange, and is mounted on the second mounting flange. In the optimally-designed oxygen flame composite plasma torch, the air intake pipe is arranged, the air outlet end of the air intake pipe extends into the electrode assembly, gas blows arc generated between electrodes to the top ends of the electrodes, and the arc is regenerated near the two adjacent electrodes after the arc reaches the top ends of the electrodes and is broken, so that a continuous sliding arc is formed between the electrodes; theoccurrence of the arc is greatly improved; the running power cost is lowered; and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of plasma torches, in particular to an oxygen-flame composite plasma torch. Background technique [0002] The plasma torch can provide high temperature and high energy density, and has a good application market in the treatment of hazardous and refractory waste, such as the melting treatment of incineration fly ash, medical waste, chemical solid waste, rock wool waste, etc. At present, the key factors affecting the use of plasma torches are the operating cost and the service life of the electrodes. The plasma torches widely used in China have the disadvantages of serious electrode burnout, frequent replacement cycles, and short service life. At the same time, the equipment cost for generating high-power arcs High and consumes a lot of power during operation. Existing experiments have shown that the power consumption of using the existing graphite electrode plasma torch to treat incineration fly ash is above...

At present, the key factors affecting the use of plasma torches are the operating cost and the service life of the electrodes. The plasma torches widely used in China have the disadvantages of serious electrode burnout, frequent replacement cycles, and short service life. At the same time, the equipment cost for generating high-power arcs High and consumes a lot of power during operation

Existing experiments have shown that the power consumption of using the existing graphite electrode plasma torch to treat incineration fly ash is above 1000 degrees / ton
