When in use, one end of the conveying arc body is coated with an anode and connected with a spout of the anode, and one end of the conveying arc head extends to the required places that the arc plasma achieves. The utility model facilitates the arc plasma jet current which is ejected from the anode of the plasma generator to be constantly and steadily sent to the appointed place, and ensures the temperature and the length of the jet current of the arc plasma to be not changed in the transmitting process.
Description
Technical field
The utility model discloses a kind of conveying arc device that is used for plasma generator, belong to the servicing unit of plasma generator.
Background technology
Direct current atmospheric pressure arc-plasma is research and most widely used a kind of plasmoid.Because be subjected to the influence of eddy flow stabilising arc and electromagnetism stabilising arc, the high temperature and high speed jet of arc-plasma is after leaving anode nozzle, very serious to entrainmenting of ambient gas, hot and cold air mixes rapidly, the energy of jet is decayed fast, cause arc-plasma just to cool down at short notice, the gradient of axial temperature is very big.It is short to show as arc plasma jet length, can only be in the effect that obtains high temperature in the very near distance of spout.So, under particular environment, in the plasma ignition system such as pulverized-coal fired boiler, in the time of arc plasma jet being transported in anode spout plasma burner central tube far away, the arc plasma jet temperature that arrives in the central tube is just very low, causes coal dust to light.If increase electric current or increase the dielectric gas flow velocity, one side is DeGrain under distance situation far away, and anode and the cathode taps to generator may cause bigger infringement on the other hand.
Summary of the invention
The purpose of this utility model provides a kind of conveying arc device of plasma generator, can successfully solve because under specific service condition, arc-plasma is transported to the technical barrier that causes from anode spout place far away.
The purpose of this utility model is to realize like this, this device is made up of the magnetic conduction of tubular, conveying arc body and the conveying arc head that Heat Conduction Material is made, carry axial alternate fin and the air-cooled groove of being a mass of of outer surface of arc head, carry the arc body and carry arc head for being connected or casting the all-in-one-piece structure, carry arc body one end to be enclosed within on the anode of plasma generator, and be connected with the anode spout, carry arc monic end to reach the place that requires arc-plasma to arrive.
The conveying arc device of aforesaid plasma generator scribbles insulating barrier at the outer surface of carrying the arc body.
The conveying arc device of aforesaid plasma generator, carrying the structure of arc head can be the straight section formula, also can be bending, the arc angle at bending structure circular arc place is realized the transmission of the various situations of arc-plasma between zero degree and 90 degree.
The utility model has the advantages that:
1, continual and steady being transported to from the distant place of anode spout of arc-plasma can be guaranteed that arc-plasma can be applied in a large amount of special environment;
2, reduce the length of anode carrier, cathode rod, anode in the plasma generator, saved a large amount of costs;
3, dwindle and safeguard the space, simplify the program of maintenance and reduced the cost of safeguarding;
4, promoted the application of arc-plasma, allowed arc-plasma be applied to the different aspect in various field and same field more flexibly.In the ignition system especially for pulverized-coal fired boiler, for country saves huge fund and a large amount of fuel oils.
Description of drawings
Fig. 1 is an example structure schematic diagram of the conveying arc device of plasma generator described in the utility model.
Fig. 2 is another example structure schematic diagram of the conveying arc device of plasma generator described in the utility model.
Embodiment
The utility model is by carrying the arc body and carrying arc head to form.It can be under temperature that does not change the arc-plasma that plasma generator produces and the situation that ambient gas is entrainmented, with arc-plasma from the spout of anode continue, the stable place that is transported to appointment.The used material of this device is magnetic conduction, Heat Conduction Material, as iron, and copper etc.After this device is used for plasma generator, the arc-plasma of anode spout ejection can be transported to the far-end of appointment, and carry finish after, the variations in temperature of arc ions body jet is little, and other character is not significant yet changes.
Because whole conveying arc device is made by permeability magnetic material, in the anode spout inserts device and near behind the device, the magnetic field that coil electricity produced also can axial distribution in carrying the arc device, because the effect in magnetic field, energy is the compression arc plasma effectively, increase electric arc and arc plasma jet rigidity, with continual and steady being transported to of arc plasma from plasma generator spout place far away.
There is fin and the air-cooled groove that axially distributes alternately at the outer surface of carrying arc head, increased the contact-making surface with outside atmosphere like this, can distribute fast and carry the first heat that produces because of contact arc and arc-plasma of arc, guarantee to carry the life-span of arc work; Carrying arc inside can continue rotational flow gas from generator, guaranteed the high concentration of the laminar flow shape arc-plasma energy of arc-plasma in rotational flow gas like this, the arc plasma physical efficiency is transported to efficiently the far-end of appointment.
Under special service condition, for example: be applied in the pulverized-coal fired boiler plasma ignition system, the part outer surface of this device scribbles heat-resisting insulating barrier, avoided carrying contacting of arc device and plasma burner like this, and significantly decay in the magnetic field that causes, and carries the intensity of arc internal magnetic field when having guaranteed operate as normal.
Below be further described with the accompanying drawing example illustrated:
Among the figure: the 1st, carry arc body, the 2nd, fin, the 3rd is carried arc head, the 4th, air-cooled groove.
Embodiment 1: conveying arc body 1 among Fig. 1 and conveying arc head 3 are made up of the material of magnetic conduction, heat conduction respectively.Carry arc body 1 to weld together with carrying arc head 3, wherein carry the outer surface of arc body 1 to scribble a layer insulating, fin and air-cooled groove are respectively distributing on the outer surface of conveying arc head 3.Carry the arc body to become 180 to spend angles between the arc head with carrying, the axial transmission of realization arc plasma.
Embodiment 2: Fig. 2 for realize plasma generator radially rotating shaft to the conveying arc device of technology.Carrying the structure of arc head is bending, and the angle of bending radian is adjusted the size of angle according to concrete applicable cases between zero degree and 90 degree.
