Abstract
The utility model discloses a rotary plasma electric arc transportation device. The device comprises a circular ring piece made of high-temperature-resistant magnetic conducting material, wherein more than two flow guide holes are uniformly formed on the circular ring piece in a ring manner, and axes of the flow guide holes and the circumference of the ring-shaped piece are arranged aslant, so that gas passes through flow guide holes on the circular ring piece to form excircle type swirl gas, and the electric arc is ensured to blow out from a spout in a rotary manner. The rotary plasma electric arc transportation device has the advantages that 1, the electric arc is blown out from the spout in a high-speed rotation manner and is in contact with the surfaces of electrodes for a short time, and the service life is greatly prolonged; 2, the length, temperature and application range of the plasma electric arc are controlled to increase according to the design requirements; 3, the structure is simple and compact, the cost is saved, and the on-site maintenance is convenient; and 4, the coal applicability of the plasma electric arc is improved, plasma ignition can be applied to different coal types in different boiler structures, and the oil-saving effect is greatly improved.
Description
Technical field
The present invention relates to a kind of plasma-arc rotationally conveying device, be used for plasma-arc is rotated the device that blows out spout at high speed, belong to the accessory of plasma generator.
Background technology
The temperature of plasma-arc can reach 6000K; Arc temperature, arc length control are technical barriers; The case of plasma electric arcing burner inner core can be found everywhere, and this all causes owing to not controlling plasma-arc length, carries electric arc to cause damage to electrode on the other hand.
Summary of the invention
The present invention is directed to the deficiency of prior art, a kind of plasma-arc rotationally conveying device is provided, it can solve the problem that output electrical arc erosion anode and cathode and arc temperature, arc length can not effectively be controlled.
For realizing above technical purpose, the present invention will take following technical scheme:
A kind of plasma-arc rotationally conveying device comprises annulus spare, and this annulus spare adopts high temperature resistant permeability magnetic material to be made, and annular is evenly equipped with plural pod apertures on the annulus spare, and the circumference of the axis of pod apertures and annular element is obliquely installed.
Said pod apertures is eight.
Cutting angle of said pod apertures and annulus disc is 30 degree or 15 degree.
According to above technical scheme, can realize following beneficial effect:
Plasma-arc rotationally conveying device of the present invention; Be connected between the anode lug and insulating sleeve of plasma generator; Insulating sleeve then is connected with negative electrode, therefore, and after the pod apertures of offering on the gas process annulus spare; Become a kind of rotational flow gas of circumcircle formula, can guarantee like this to blow out spout to electric arc with the effect of rotating.Have the following advantages:
1, the electric arc high speed rotating goes out spout, and very short with the time of contact of electrode surface, improve useful life greatly;
2, can be according to designing requirement, the length of control plasma-arc, temperature, the scope of application increase;
3, compact conformation is simple, practices thrift cost and on-site maintenance conveniently;
4, improve the coal adaptability of plasma-arc, let plasma ignition be applied to the different coals under the different boiler structures, oil-saving effect improves greatly.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Wherein: annular element 1; Pod apertures 11.
Embodiment
Accompanying drawing discloses the structural representation of preferred embodiment involved in the present invention without limitation; Below will combine accompanying drawing that technical scheme of the present invention at length is described.
As shown in Figure 1, plasma-arc rotationally conveying device of the present invention comprises annulus spare, and this annulus spare adopts high temperature resistant permeability magnetic material to be made, and annular is evenly equipped with plural pod apertures on the annulus spare, and pod apertures described in the accompanying drawing is eight; And the axis of pod apertures and the circumference of annular element are obliquely installed.Cutting angle of said pod apertures and annulus disc is 30 degree or 15 degree.
During use; Annular element of the present invention is connected between the anode lug and insulating sleeve of plasma generator; Insulating sleeve then is connected with negative electrode, therefore, and after the pod apertures of offering on the gas process annulus spare; Become a kind of rotational flow gas of circumcircle formula, can guarantee like this to blow out spout to electric arc with the effect of rotating.
