Abstract

A plasma pyrolysis water spray gun for a millipore membrane cathode is disclosed and the invention relates to a plasma spray gun. The spray gun consists of a rear seat, the cathode, a spiral fluid director, an anode sheath and an anode. A water supply liquid guide tube and a cathode connecting rod are arranged in a revolving body of the rear seat, the cathode consists of a millipore membrane cathode head and a cathode sleeve, the millipore membrane cathode head has a millipore filtration membrane structure which is formed via metal powder sintering operation, the millipore membrane cathode head is inserted into a wall body of a front part of the cathode sleeve, a spiral liquid guide rib is arranged in the revolving body of the spiral fluid director, a screw pitch space of the spiral liquid guide rib forms a spiral liquid guide passageway, the cathode is connected on a front end of the cathode connecting rod, a rear end of the spiral fluid director is mounted on the rear seat, the anode sheath carrying the anode is mounted on a front end of the spiral fluid director, a head part of the cathode enters an inlet space of a Venturi jet pipe of a rear end of the anode, the inlet space of a Venturi jet pipe forms an electric discharge zone, and an inner space of an expansion segment of the Venturi jet pipe of the anode forms an injection chamber. According to the plasma pyrolysis water spray gun, heat of the cathode head can be rapidly absorbed via latent heat of water vaporization, and therefore the cathode cannot be easily ablated.

Description

technical field [0001] The invention relates to plasma equipment, in particular to a plasma spray gun. 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, waste incineration and waste treatment, etc. The plasma treatment method is very different from the general method. Plasma is a state formed under the ionosphere or discharge phenomenon. With the discharge phenomenon, excited atoms, excited molecules, dissociated atoms, free atomic groups, Active chemicals of groups of atoms or molecular ions and their reactions resulting from collisions with other chemicals. 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 temperature through mutual collision, and the temperature can reach more than tens of thousands of degrees.
