Abstract

An internal arc plasma gun relates to plasma heating equipment, and consists of a front gun body, a back base and a first electrode, wherein an arc cavity and a cooling water jacket are arranged inside the front gun body; the head part of the first electrode stretches into the arc cavity; the arc cavity and the head part of the first electrode stretching into the arc cavity form an internal arc generator; a metal component at an inlet forms a second electrode; and when the internal arc plasma gun works, an arc is generated inside the arc cavity, sprayed out from a compressing nozzle, and intensely heated after being compressed so as to form a plasma torch. By decomposing water molecules inside the arc cavity, energy of the high-temperature plasma arc is concentrated, the internal arc plasma gun has the characteristics of high heating efficiency and high decomposition rate of the water molecules, is applicable to a daily garbage gasifying furnace, a coal gasifying furnace, an industrial polymer waste gasifying device, a water-pyrolyzing hydrogen making device and a boiler, and compared with the conventional technology, can reduce the consumption of coal resources, improve the quality of synthesized gas and reduce emission of greenhouse gas.

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...
