Problems solved by technology

[0004] However, in the actual industrial production process, the composition of industrial waste gas is relatively complex, and the composition of industrial waste gas will often change. Even if an induction alarm device is used, it cannot ensure that UV photolysis and low-temperature plasma equipment will not cause deflagration accidents.

Abstract

The invention discloses a UV photolysis and low-temperature plasma anti-explosion device and method. The device comprises a first exhaust pipe and treatment liquid, wherein the first exhaust pipe extends into a filtering pool; the treatment liquid is put into the filtering pool; an electric gas inlet valve is arranged above a treatment pool; a waste gas concentration monitoring instrument is arranged under a first anti-explosion negative pressure wind pipe for connecting the filtering pool and a UV photolysis device; behind the UV photolysis device, a low-temperature plasma device and a negative pressure fan device are connected through a second anti-explosion negative pressure wind pipe and a third anti-explosion negative pressure wind pipe sequentially. By using the method and the device, the damage due to explosion and combustion because the waste gas concentration reaches the explosion limit during the waste gas treatment by the anti-UV photolysis and low-temperature plasma equipment can be avoided.

Description

technical field [0001] The invention relates to a V photolysis and low-temperature plasma explosion-proof device, in particular to a UV photolysis and low-temperature plasma explosion-proof device and method. Background technique [0002] UV photolysis is the use of special high-energy high-ozone UV ultraviolet light beams to irradiate odorous gases, cracking odorous gases such as: ammonia, trimethylamine, hydrogen sulfide, methyl sulfide, methyl mercaptan, methyl sulfide, dimethyl disulfide, carbon disulfide and benzene The molecular bonds of ethylene, sulfide H2S, VOCs, benzene, toluene, and xylene oxidize and combine free pollutant molecules with ozone to form small-molecule harmless or low-harm compounds, such as CO2, H2O, etc. [0003] In the process of plasma generation in low-temperature plasma, the instantaneous high energy generated by high-frequency discharge is enough to open the chemical bonds in some harmful gas molecules to decompose them into simple atoms or h...
