Abstract

The invention relates to the technical field of waste treatment, in particular to a plasma generator. The plasma generator comprises a cathode, an arc striking anode and an anode which are sequentially and coaxially connected in series. The cathode is provided with a cathode head, a cathode sleeve and a first cooling channel for cooling the cathode head. The anode is provided with an anode lining,an anode jacket and a second cooling channel for cooling the anode lining. The arc striking anode comprises an arc striking anode lining, a plasma generating chamber which is located on one side, facing towards the cathode head, of the arc striking anode lining and is used for the arc striking anode to break down the working gas to form a plasma, and a preheating chamber which is arranged aroundthe outside of the arc striking anode lining for heat exchange between the low-temperature working gas and the high-temperature arc striking anode lining, wherein the preheating chamber and the plasmagenerating chamber are communicated with each other. The plasma generator has the advantages of simple structure, few parts, small volume and high heat recovery rate.

Description

technical field [0001] The invention relates to the technical field of waste treatment, in particular to a plasma generator. Background technique [0002] At present, plasma technology has been widely used in many fields, and the plasma torch generated by it has a high temperature, which can instantly melt difficult-to-melt objects. In terms of destroying secret-related media, an efficient method that can completely destroy a variety of different secret-related media at the same time is needed, and the use of plasma technology can meet this requirement. The plasma torch generated by the plasma generator can generate a high temperature of over 3000K, which can instantly melt hard disks, magnetic disks, U disks, chips and other confidential media that are difficult to destroy. The general method of destroying secret-related media is difficult to meet the destruction of different media. The use of plasma technology provides a new method for destroying secret-related media. ...
