Method for treating waste by adopting microwave plasma

Abstract

The invention discloses a method for treating waste by adopting a microwave plasma torch. The method comprises the following steps: pretreatment of waste, namely preparing solid waste, liquid waste and gaseous waste, and crushing the solid waste by virtue of a crushing device; and pyrolysis, namely generating a plasma torch by carrying out ionization on gas by utilizing a microwave plasma generation device, and carrying out the pyrolysis on the pre-treated waste by virtue of the plasma torch, wherein organic matters in the waste are pyrolyzed into micromolecular substances such as C, H2, CO, and CH4, and inorganic matters in the waste are molten at the high temperature to form a matter in a glass state. According to the method, the waste is pyrolyzed by virtue of the plasma torch generated by the microwave plasma generation device, the waste is pyrolyzed into the micromolecular substances, such as carbon oxide, carbon powder, methane, and hydrogen, and the matter in the glass state, no harmful matter is generated in the treatment process, the secondary pollution for the environment is avoided, the treatment procedure is simple, and the efficiency is relatively high.

Description

technical field [0001] The invention relates to a method for treating waste with a microwave plasma torch. Background technique [0002] The existing waste treatment is generally carried out through multiple crushing, multiple screening, burning and packaging processes. The process is extremely complicated, and new waste will still be generated during the treatment process, which cannot be treated cleanly. Dioxins and furans are often produced during the process, and the pollutants are extremely harmful to the environment and human body; the method of using high-voltage arc discharge plasma torch to treat waste has high energy consumption and short electrode life (generally, the electrode life is 100-200 hours Left and right), poor stability and other shortcomings, can not be widely used. [0003] It can be seen that the existing garbage treatment method has relatively large disadvantages, and there is room for further improvement. Therefore, the present invention provides ...
