Putting absorbing liquid preparation vessel, carry out configuring absorbing liquid according to harmful gas in absorbing liquid preparation vessel, absorbing liquid adheres to paint for absorbable
The liquid chemical substance of harmful gas in bag stove, the inner spray piping that arranges of absorbing liquid spraying layer 4, absorbing liquid sprays through absorbing liquid
The spray piping of layer 4 is vaporific unrestrained, spreads in retort 1, is finally deposited in slurry pool 2；
General enamel-cover boiler tube road 3 is positioned at slurry pool 2 top, a little higher than slurry pool 2, it is ensured that discharge into from enamel-cover boiler tube road 3
Harmful gas has the climb of maximum, fully can contact fusion with the absorbing liquid fallen；
Catalyst reaction device 5, catalyst reaction device 5 generally heating or ionization device it is provided with in described absorbing liquid spraying layer 4
Deng, the absorbing liquid carrying harmful substance can be carried out catalytic reaction so that it is reduction release harmful substance again；
The top of described retort 1 also sets up purifier, and described purifier includes burn pot 6 and dedusting groove 7, described reaction
Tank 1, burn pot 6 and dedusting groove 7 are contacted by pipeline, arrange fuel dust and agitating device 16, fuel dust one in burn pot 6
As with carbon dust, agitate to be diffused in by carbon dust in burn pot 6 by agitating device 16, concentration is had by ignition carbon dust
Evil gas burns, and forms stable non-toxic gas and enters back into dedusting groove 7, arranges porous panel 13, dedusting groove in dedusting groove 7
Filling water in 7, gas forms multiple minute bubbles through porous panel 13, is fully contacted with water, dust granules therein just precipitation
In water, the gas such as some carbon dioxide, carbon monoxide, sulfur dioxide also incorporates in water；
The top of retort 1 also sets up decomposer, and described decomposer includes air pump 8, swelling bag 9 and high-temperature pipe 10, point
When solving device use, concentrated gas pipeline 6 is closed mode, and described air pump 8 connects retort 1, and air pump 8 is arranged on swelling bag 9
On, described swelling bag 9 is provided with air flow valve 11, in air pump 8 abstraction reaction tank 1, gas enters swelling bag 9, the gas of extraction
For contacting the gas of absorbing liquid, the concentration of its harmful substance is diluted, and swelling bag 9 overdraught valve 11 is closed mode,
After swelling bag 9 is expanded to certain limit, opening air flow valve 11, high-temperature pipe 10 is positioned at air flow valve 11, having of dilution
Evil gas is quickly blown out, and simultaneously through high-temperature pipe 10 by high-temperature heating, further, is provided with in described high-temperature pipe 10
Bocca 14 and high temperature silk screen 15, owing to the harmful substance contents that adulterates in the gas in swelling bag 9 is low, it is not necessary to obtain filling of high temperature
Divided combustion and heat treated, so it is shorter to typically last for the time the step for that internal gas being blown out by swelling bag 9, therefore high-temperature pipe
Road 10 needs the time heating blow gas the shortest, and gas is heat treatment during quickly flowing out and be enough to it
In harmful substance remove.
Further, being additionally provided with circulating line 12 outside described retort 1, the two ends of described circulating line 12 connect respectively
Absorbing liquid spraying layer 4 and slurry pool 2, described circulating line 12 is provided with compression pump, it is achieved that recycling of absorbing liquid.

Structure, the diameter of several ring body structurcs is arranged from large to small, and the ring body structurc of small diameter is always provided in bigger ring body knot
In structure.
Harmful gas in enamel-cover stove enters retort 1 from enamel-cover boiler tube road 3, and it is vaporific that absorbing liquid spraying layer 4 sprays
Absorbing liquid fall contact with the harmful gas flowed up, absorbing liquid the harmful substance in harmful gas is absorbed in a large number after in the lump
Falling into slurry pool 2, the pipeline leading to decomposer is opened, and under the extraction of air pump 8, the gas being diluted is inhaled into swelling bag 9,
Opening air flow valve 11 after certain limit to be achieved, high-temperature pipe 10 is opened the gas releasing swelling bag 9 and is carried out heat treated,
After this step terminates, closing the pipeline of decomposer, the catalyst reaction device 5 in retort 1 is opened, the nuisance in absorbing liquid
Matter is released, and burn pot 6 is opened, and the harmful substance that concentration is higher enters burn pot 6, starts burning with burning mix dust,
Then noxious substance is mixed to form other chemical compound gas with burning dust high temperature, and gas and dust that burning produces enter dedusting
Groove 7, gas is received dust and some hydrophilic gas, is finally discharged to air by dedusting groove 7.
The above, only the application preferably detailed description of the invention, but the protection domain of the application is not limited thereto,
Any those familiar with the art in the technical scope that the application discloses, the change that can readily occur in or replacement,
All should contain within the protection domain of the application.Therefore, the protection domain of the application should be with scope of the claims
It is as the criterion.
