Belong to smelting, heating plasma manufacture nano material, cutting, the processing of waste incineration waste etc..Plasma is showed by ionic discharge
As being formed by a kind of state, along with electric discharge will generate excited atom, excitation molecule, dissociation atom, free atomic group,
The activity chemistry object of atom or molecular ion group and they reacted with caused by other chemicals collisions.In plasma
In spray gun, discharge process makes work gas molecule lose outer-shell electron and form ionic condition, is mutually collided and generates high temperature,
The central temperature of plasma flare may be up to tens of thousands of degree Celsius or more, and torch lip temperature also can reach thousands of degree or more, quilt
When the substance of processing is impacted by high-temperature plasma, molecule will be decomposed, atom will reconfigure and generate new object
Matter makes harmful substance become innocuous substance.
On coal gasification production line, gas making is carried out with coal after water vapour is passed through pyrolytic and is reacted, makes coal more
It is easy gasification, improves the rate of gasification of coal, realizes and saves coal resources；In house refuse or industrial organic wastes disposal system

There is the access of unstripped gas input interface in channel, and there is unstripped gas spout at the head end center of cathode, and feed gas passage passes through unstripped gas spout
It is communicated to contraction chamber.Water vapour is sprayed into the region of discharge in contraction chamber by the spout at cathode head end center by the patent, steams water
The heat that vapour is absorbed into cathode head end is preheated, while anticathode head end has cooling effect, overcomes Conventional plasma
The shortcomings that spray gun body electrode easy ablation.But since the patent is taken " the head end side wall of cathode fits closely over cathode base
Seat axis front end wall body in, the tail end of cathode fits closely in the wall body of cathode pedestal rear end " measure carry out water jacket it is close
Envelope, the effect of expanding with heat and contract with cold of material will be such that cathode loosens, and cause shift cathode and seal unreliable, the cooling water in water jacket
It is easy to leak into the region of discharge in contraction chamber, influences spray gun normal work.
