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 efficient treatment process in a kind of toxic organic exhaust gas, including sequentially connected purification dress
Set 1, enrichment facility 2 and burner 3, purification device 1 includes tipping tube 4 and vertical pipe 5, tipping tube 4 diagonally downward, tipping tube
4 upper ends are 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
It is respectively arranged 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 10,10 top of clay layer
It is provided with 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, taper by bracket
The outer wall of 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 burner 16, ring 17 of igniting is annular, and section is ellipse half
It is round；Ring 17 of igniting is internally provided with a main channel and a plurality of subchannel, and main channel is connected to one end of a plurality of subchannel, another
It holds as the hole for 17 outer surface of ring of igniting.
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 passes through first
Spongy layer 8 is full of moisture on first spongy layer 8, can adsorb exhaust gas formaldehyde at this time, pass through again after then passing through individual event ventilated membrane 7
The second spongy layer 9, the first spongy layer 8 and the second spongy layer 9 are crossed other than absorbing and being dissolved in the substance of water in exhaust gas, also has and stablizes
The effect of individual event ventilated membrane 7, otherwise one-way ventilating film is under regular one-way ventilating effect, or gradually fenestra increases, and loses
The effect of one-way ventilating；Then exhaust gas enters back into clay layer 10, continues the absorption of exhaust gas, then passes through hydrophobic permeable membrane again
It enters in organic solvent；Absorption before entering back into organic solvent, primarily to by large particulate matter and exhaust gas in exhaust gas
Temperature reduce and be dissolved in water substance absorption fall, subsequently into organic solvent, enter enrichment facility by the exhaust gas of purification
It is concentrated in 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 tracheae
In, another part has entered in taper tracheae, and combustion apparatus jets out flames downwards at this time, and peripheral flame is in ring of igniting
Under the action of, formed it is intermediate small, below big flame, in addition, dissipated outward from venthole into the flame in taper tracheae, from
And flame flame envelope is more blown it is outside, under the action of flame flow, exhaust gas more towards vertical tracheae edge, and this
When, by the effect of ignite ring and taper tracheae, the flame envelope of the edge of vertical tracheae is most, and passes through the process of flame more
It is long；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 reality
Existing 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.
