Description of the drawings
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
Accompanying drawing to be used needed for having technology description is briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments described in invention, for those of ordinary skill in the art, on the premise of not paying creative work,
Can be with according to these other accompanying drawings of accompanying drawings acquisition.
Fig. 1 is the floor map of fluorine-containing one specific embodiment of alkane burned waste gas processing meanss of the present invention.
Specific embodiment
The present invention is described in detail for shown each embodiment below in conjunction with the accompanying drawings, but it should explanation, these
Embodiment not limitation of the present invention, those of ordinary skill in the art according to these embodiment institute work energy, method,
Or the equivalent transformation or replacement in structure, belong within protection scope of the present invention.
The fluorine-containing alkane burned waste gas handling process of the present invention comprises the steps：
S1, the incinerator with refractory material is preheated, fluorine-containing alkane waste gas is passed through in the incinerator after preheating.
Wherein, during preheating, the incinerator is preheated to into more than 1100 DEG C by fuel, so as to for follow-up halothane hydrocarbon it is useless
Gas carries out pyrolysis and prepares.The refractory material is chromium oxide and aluminium sesquioxide, the chromium oxide and aluminium sesquioxide content
More than 95wt%, and the chromic oxide content >=10 wt %.So as to by using the incinerator with refractory material, Neng Gouke
To prevent high concentration HF etching apparatus, the service life of extension device.
S2, according to the molecule content of fluorine-containing alkane in waste gas, be passed through vapor in incinerator and reacted.
S3, it is passed through natural gas in incinerator, to control the furnace temperature of incinerator.
S4, the amount of filling into for by fluorine-containing alkane waste and natural gas total amount, controlling air in proportion.
Wherein, the purpose for controlling the amount of filling into of air in proportion is that it is same that control air meets burning Minimum requirements oxygen
In time control tobacco curing gas, HF concentration is not higher than 5%, it is ensured that burn stable, to realize that waste gas is fully pyrolyzed and improves service life of equipment
Purpose.Specifically, the amount of filling into of the control air is by being controlled as follows：By exhaust gas flow measured value and
Amount of natural gas measured value is calculated by molecular formula and determines ratio value, is added by both ratios and is determined the air amount of filling into, as benefit
The set-point of air frequency conversion fan, the effusion meter of airduct line as actual air volume measured value, by between measured value and set-point
Bias adjustment frequency conversion fan rotating speed, it is ensured that fill into air quantity infinite approach set-point.
S5, by after burning high-temperature flue gas send into graphite chilling tower, the hydride of halogen in the flue gas after chilling is carried out
Water absorption.
