Non-transfer arc plasma gun and plasma device with non-transfer arc plasma gun

Abstract

The invention discloses a non-transfer arc plasma gun and a plasma device with the non-transfer arc plasma gun; the non-transfer arc plasma gun comprises an insulation shell, an air inlet pipe and ananode, wherein the air inlet pipe is arranged on the insulation shell, and one end of the air inlet pipe extends into a containing space; the part, extending into the containing space, of the gas inlet pipe is provided with a cathode; the cathode is electrically connected with the gas inlet pipe; a gas passage in communication with the gas inlet pipe is arranged in the cathode; the gas passage isprovided with a gas outlet arranged on the outer peripheral wall of the cathode; the anode is arranged on the insulation shell; a gas through hole communicated with the containing space is formed in the anode; on the flow path of the plasma gas, the anode is located downstream of the cathode. According to the non-transfer arc plasma gun, the anode is integrated on the insulation shell; the anode and the cathode are matched to generate a non-transfer plasma arc; extra external anodes do not need to be additionally connected, so operations are convenient, and production cost is saved. The non-transfer arc plasma gun is simple in structure, can be manufactured finely, and has strong practicability.

Description

technical field [0001] The invention relates to the field of plasma technology, in particular to a non-transferred arc plasma gun and plasma equipment with the same. Background technique [0002] With the development of science and technology, plasma technology is more and more widely used in the fields of weapon system stealth, communication and detection, aircraft interception, environmental governance, and space propulsion. Plasma equipment mainly includes transferred arc plasma equipment and non-transferred arc plasma equipment. Transferred arc plasma equipment is simple in structure and cheap in price, but it needs an external anode in actual use, which brings a lot of inconvenience to the operation. Although non-transferred arc plasma equipment is easy to operate, it is Expensive, high cost of use. [0003] In order to solve the above problems, in the related art, a non-transferred arc plasma device is proposed, which mainly includes a cathode part, an intake ring, an...
