Self-cleaning fireproof system for plasma VOCs degradation device

Abstract

The invention discloses a self-cleaning fireproof system for a plasma VOCs degradation device. The self-cleaning fireproof system is characterized by comprising a double-dielectric barrier discharge plasma VOCs degradation subsystem, a gas uniform distribution subsystem, a tar cleaning subsystem and an emergency fire extinguishing subsystem. The double-dielectric barrier discharge plasma VOCs degradation subsystem is used for degrading VOCs entering the reactor; the gas uniform distribution subsystem is used for dispersing gas entering the reaction device; the tar cleaning subsystem is used for cleaning tar which is degraded by plasmas and then accumulated in the reaction device; and the emergency fire-fighting subsystem is used for discharging water and fighting fire when an emergency fire occurs. According to the self-cleaning fireproof system for the plasma VOCs degradation device, the problem that post-treatment of degradation products is difficult in the existing plasma VOCs removal technology is solved, and the safety of plasma VOCs degradation equipment is improved.

Description

technical field [0001] The invention relates to a self-cleaning fire prevention system for a plasma degradation VOCs device, belonging to the technical field of waste gas treatment. Background technique [0002] At present, my country's definition of VOCs is: a general term for organic compounds that are volatile under certain conditions, mainly non-methane total hydrocarbons (such as alkanes, alkenes, alkynes, aromatics, etc.), oxygen-containing organic compounds (such as aldehydes, Ketones, ethers, etc.), nitrogen-containing organic compounds, sulfur-containing organic compounds, etc. VOCs are toxic and carcinogenic, and are the precursors of PM2.5; when they enter the atmosphere, they will undergo a extinction chemical reaction, which will further lead to the destruction of the ozone layer, which is extremely harmful to the human body and the environment. VOCs are volatile and have complex components. The current treatment processes mainly include: adsorption method, abso...
