A cathode with a microporous membrane structure

Abstract

A cathode with a microporous membrane structure and a plasma pyrolysis water spray gun, relating to a plasma spray gun, the cathode is composed of a microporous membrane cathode head and a cathode sleeve, and the micropores of the microporous membrane cathode head form a filtration channel for water molecules , the microporous membrane cathode head is embedded in the wall body at the front of the cathode sleeve, and the head of the microporous membrane cathode head protrudes from the front end of the cathode sleeve; the plasma pyrolysis water spray gun consists of a rear seat, a cathode, a spiral deflector, The anode sleeve and the anode are composed of a water supply guide pipe and a cathode connecting rod in the rotator of the rear seat, and a spiral guide rib is provided in the rotator of the spiral deflector. The anode is a venturi nozzle structure, and the anode is installed in an embedded manner. In the anode sleeve, the space between the outer wall of the anode and the inner wall of the anode sleeve constitutes a cooling water jacket, the cathode is connected to the front end of the cathode connecting rod of the rear seat, the rear end of the spiral deflector is installed on the rear seat, and the anode sleeve and the anode are installed on the spiral front end of deflector. The invention utilizes the latent heat of vaporization of water to quickly absorb the heat of the cathode head, so that the cathode is not easy to be 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.
