Cathode of microporous membrane structure and plasma pyrolysis water spraying gun

Abstract

The invention relates to a plasma spraying gun and discloses a cathode of a microporous membrane structure and a plasma pyrolysis water spraying gun. The cathode is composed of a microporous membrane cathode head and a cathode sleeve, a hydrone filter channel is formed by micropores of the microporous membrane cathode head, the microporous membrane cathode head is embedded in the wall of the front portion of the cathode sleeve, and the head portion of the microporous membrane cathode head stretches out of the front end of the cathode sleeve. The plasma pyrolysis water spraying gun is composed of a rear base, the cathode, a spiral flow diverter, an anode sleeve and an anode, wherein a rotation body of the rear base is internally provided with a water supply guide pipe and a cathode connection rod, a rotation body of the spiral flow diverter is internally provided with a spiral guide rib, the anode is of a Venturi spraying pipe structure and is embedded in the anode sleeve, the space between the outer wall of the anode and the inner wall of the anode sleeve forms a cooling water sleeve, the cathode is connected with the front end of the cathode connection rod of the rear base, the rear end of the spiral flow diverter is installed on the rear base, and the anode sleeve and the anode are installed at the front end of the spiral flow diverter. Heat energy of the cathode head is rapidly absorbed through latent heat of vaporization of water, so that the cathode is not prone to ablation.

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.
