Embodiment Construction

[0016] The accompanying drawings disclose, without limitation, the structural schematic diagrams of the preferred embodiments involved in the present invention; the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0017] like figure 1 As shown, the plasma arc rotary conveying device described in the present invention includes a circular ring, which is made of high-temperature resistant and magnetically conductive material, and more than two guide holes are evenly distributed on the circular ring. There are eight diversion holes in the drawings; and the axes of the diversion holes are inclined to the circumference of the ring. The tangential angle between the diversion hole and the circular surface is 30 degrees Celsius or 15 degrees Celsius.

[0018] When in use, the annular piece of the present invention is connected between the anode sleeve and the insulating sleeve of the plasma generator, and th...

Abstract

The invention discloses a plasma arc rotational conveying device which comprises a circular ring part, wherein the circular ring part is made of a high-temperature-resistant magnetoconductive material; more than two diversion holes are annularly and evenly distributed on the circular ring part; and the axial lines of the diversion holes are inclined relative to the circumference of the circular ring part. Therefore, the air becomes an excircle type rotational flow gas after passing through the diversion holes arranged on the circular ring part, thereby ensuring that arcs can be blown out of a nozzle in a rotation manner. The plasma arc rotational conveying device has the following advantages: 1, the arcs are blown out of the nozzle in a high-speed rotation manner, so that the time of contact with the electrode surface is very short, thereby greatly prolonging the service life; 2, the lengths of the plasma arcs can be controlled according to design requirements, thereby widening the temperature and the serviceable range; 3, the structure is compact and simple, the cost is saved, and the field maintenance is convenient; and 4, the coal adaptability of the plasma arcs is improved, plasma ignition can be applied to different kinds of coal for different boiler structures, and the oil-saving effect is greatly improved.

Description

technical field [0001] The invention relates to a plasma arc rotary conveying device, which is a device for rotating the plasma arc at high speed and blowing it out of a nozzle, belonging to an auxiliary part of a plasma generator. Background technique [0002] The temperature of the plasma arc can reach 6000K. Controlling the arc temperature and arc length is a technical problem. There are many cases where the plasma arc penetrates the inner cylinder of the burner. This is caused by the inability to control the length of the plasma arc. It is bound to cause damage to the electrodes. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a plasma arc rotary conveying device, which can solve the problems that the output arc burns the anode and cathode, and the arc temperature and arc length cannot be effectively controlled. [0004] For realizing above technical purpose, the present invention will take following techn...
