Spray head assembly, the gas outlet at the top of the spray column, be arranged on the air inlet and spray the reaction between head assembly
Area, for by Fe3+Be converted to Fe2+Electroreduction pond and hydrogen peroxide reservoir, wherein the electroreduction pond and hydrogen peroxide reservoir point
It is not connected by the first pipeline and second pipe that are provided with the spray head assembly, first pipeline and second pipe exist
Pipe-line mixer is installed with described one end for being connected of spray head assembly, for by the Fe in the first pipeline2+With second pipe
Interior hydrogen peroxide is chemically reacted.
Further, water circulating pump, the hydrogen peroxide reservoir and are installed between the electroreduction pond and the first pipeline
Metering pump is installed between two pipelines.
Further, the air inlet, which closes on, is arranged on above the waste liquid tank.
Further, the spray head assembly is multiple rows of spray head, and multiple rows of spray head is in be arranged horizontally in institute up and down
State in spray column inner cavity.
Compared with prior art, this programme utilizes Fe by the electroreduction pond by being provided with and hydrogen peroxide reservoir structure2+
Chemically reacted with the hydrogen peroxide in hydrogen peroxide reservoir, produce hydroxyl radical free radical (OH) and sprayed through spraying head assembly
With being chemically reacted from the organic exhaust gas inside air inlet, the pernicious gas in organic exhaust gas is handled, Fe2+With it is double
Oxygen water caused Fe after reacting3+Under fall in waste liquid tank, the Fe in waste liquid tank3+The transfer of electroreduction pond is transferred to again
Change Fe into2+, recycle.
Brief description of the drawings

Embodiment
With reference to specific embodiment, the utility model is described in further detail.
Referring to shown in attached drawing 1, the utility model provides a kind of novel waste gas treatment device, the novel waste gas treatment device bag
Include spray column 1, be arranged on 1 inner cavity bottom end of spray column be used for collect Fe3+The waste liquid tank 4 of ion, be arranged under spray column 1
Portion and what is be connected with its inner cavity be used for air inlet 3, the spray head that is arranged at 1 upper lumen of spray column that organic exhaust gas enters
Component 2, be arranged on spray head assembly 2 region be used for add Fe3+Reaction packing area 13, the outlet positioned at the top of spray column 1
Mouthfuls 5, it is arranged on air inlet 3 and sprays reaction zone between head assembly 2, for by Fe3+Be converted to Fe2+Electroreduction pond 6 and
Hydrogen peroxide reservoir 9.Wherein electroreduction pond 6 and hydrogen peroxide reservoir 9 the first pipeline 10 and second pipe 11 by being provided with respectively
It is connected with spray head assembly 2, the first pipeline 10 and second pipe 11 are provided with pipeline on the one end being connected with spray head assembly 2
Mixer 12, for by the Fe in the first pipeline 102+Chemically reacted with the hydrogen peroxide in second pipe 11, for producing hydroxyl
Base free radical (OH).Electroreduction pond 6 its it is outer be connected in DC current, electroreduction pond 6 its by the water circulating pump 7 that is connected with by its
Interior Fe2+It is delivered to by the first pipeline 10 at spray head assembly 2 and participation reaction is contacted with hydrogen peroxide.Hydrogen peroxide lives pond by setting
Hydrogen peroxide in it is delivered at spray head assembly 2 and participates in reacting by the metering pump 8 being equipped with by second pipe 11.First pipeline
10 and second pipe 11 in hydrogen peroxide converged by the pipe-line mixer 12 being provided with entering at spray head assembly 2,
