Arc plasma gun

Abstract

The invention discloses an arc plasma gun and relates to plasma heating equipment. The gun is characterized by consisting of an anode, a cathode, a gun barrel and a back seat, wherein the anode has a hollow annular body structure; a cooling groove is formed in an annular body and provided with a cooling water interface; the cathode has a hollow stick body structure; a cooling cavity is formed in a stick body and provided with a working water interface; the back seat has a disc body structure; the center of a disc body is provided with a passage hole; the anode, the gun barrel and the back seat are arranged coaxially; the back end of the gun barrel is connected to the back seat so as to form a gun body; the anode is connected to the front end of the gun barrel; the annular space of the anode forms a jet orifice; the internal space of the gun barrel forms an air chamber; the front end of the cathode extends into the gun barrel through the passage hole on the back seat; a discharge spaceis formed in the space between the front end of the cathode and the anode; a back stick body of the cathode is outside the gun body; and the working water interface is connected to the cooling cavityof the cathode from the outside of the gun body. The efficiency of the gun is almost 100 percent and the anode and the cathode are protected from being ablated more effectively.

Description

technical field [0001] The invention relates to electric heating equipment, in particular to a plasma heating equipment. Background technique [0002] At present, plasma technology has been widely used, industrially used in plasma ignition, plasma spraying, metal smelting, plasma heating to manufacture nanomaterials, cutting, garbage incineration and waste treatment, etc. In recent years, the technology of using plasma to treat dangerous and harmful wastes and household garbage has developed rapidly. The plasma treatment method is quite different from the general incineration method. This state, accompanied by the discharge phenomenon, will generate active chemicals of excited atoms, excited molecules, dissociated atoms, free atomic groups, atomic or molecular ion groups, and their collisions with other chemical substances. In the plasma generator, the discharge effect causes the working gas molecules to lose the outer electrons and form an ion state, which generates high t...
