Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention；Technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description；Obviously；Described embodiments are only a part of the embodiments of the present invention；Instead of all the embodiments.It is based on
Embodiment in the present invention；It is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment；It shall fall within the protection scope of the present invention.
Please refer to Fig. 1-4, VOCs treatment process in a kind of toxic organic exhaust gas, including sequentially connected purification device 1,
Enrichment facility 2 and burner 3, purification device 1 include tipping tube 4 and vertical pipe 5, tipping tube 4 diagonally downward, on tipping tube 4
End is active carbon layer 6；The middle position of tipping tube 4 and vertical pipe 5 is provided with one-way ventilating film 7,7 both ends of one-way ventilating film difference
It is provided with the first spongy layer 8 and the second spongy layer 9,9 upper end of the second spongy layer is provided with clay layer 10, is arranged above clay layer 10
There is hydrophobic permeable membrane 11, the top of hydrophobic permeable membrane 11 is provided with organic solvent 12；
Burner 3 includes vertical tracheae 13, and the inside of vertical tracheae 13 supports the bottom end of taper tracheae 14 by bracket,
The outer wall of taper tracheae 14 is provided with multiple ventholes 15, and the top of taper tracheae 14 is provided with burner 16.
First spongy layer 8 and the second spongy layer 9 are wet sponge.
Ring 17 of igniting is provided between taper tracheae 14 and combustion apparatus 16, ring 17 of igniting is annular；It ignites inside ring 17
It is provided with a main channel and a plurality of subchannel, main channel is connected to one end of a plurality of subchannel, and the other end is 17 appearance of ring of igniting
The hole in face.
Working principle:
The exhaust gas being collected into is passed through to the upper end of tipping tube first, active carbon layer 6 is first passed around and is adsorbed, then passed through
First spongy layer 8 is full of moisture on first spongy layer 8, exhaust gas formaldehyde can be adsorbed at this time, after then passing through one-way ventilating film 7
Using the second spongy layer 9, the first spongy layer 8 and the second spongy layer 9 also have other than absorbing and being dissolved in the substance of water in exhaust gas
Stablize the effect of one-way ventilating film 7, otherwise one-way ventilating film is under regular one-way ventilating effect, or gradually fenestra increases,
Lose the effect of one-way ventilating；Then exhaust gas enters back into clay layer 10, continues the absorption of exhaust gas, then again by hydrophobic
Air film enters in organic solvent；Absorption before entering back into organic solvent, primarily to by exhaust gas large particulate matter and
The substance absorption that the temperature of exhaust gas reduced and be dissolved in water is fallen, and subsequently into organic solvent, the exhaust gas by purification enters concentration
It is concentrated in device 2, subsequently into burner；
Exhaust gas enters in the vertical tracheae in burner, and gas can be divided into 2 parts, and 1 part does not fall under taper
In tracheae, another part has been entered in taper tracheae, and combustion apparatus jets out flames downwards at this time, and peripheral flame is drawing
Under the action of fire ring, formed it is intermediate small, below big flame, in addition, into the flame in taper tracheae from venthole outward
Dissipate, thus flame flame envelope is more blown it is outside, under the action of flame flow, exhaust gas more towards vertical tracheae edge,
And at this point, the flame envelope of the edge of vertical tracheae is most by the effect of ignite ring and taper tracheae, and pass through the mistake of flame
Cheng Gengchang；At the same time, it ignites and is additionally provided with channel inside ring, the combustion-supporting ingredient such as oxygen can be passed through to main channel, so as to
Enough realize that flame is more prosperous, to realize the more thorough combustion degradation of exhaust gas, realization reaches zero emission standards.
It is described above；It is merely preferred embodiments of the present invention；But scope of protection of the present invention is not limited thereto；
Anyone skilled in the art is in the technical scope disclosed by the present invention；According to the technique and scheme of the present invention and its
It improves design and is subject to equivalent substitution or change；It should be covered by the scope of protection of the present invention.
