The flash-point of methyl alcohol is 12 DEG C, and self-ignition point is 463 DEG C, and the flash-point of pyridine is 17 DEG C, and self-ignition point is 482 DEG C.Because the organic matter such as methyl alcohol, pyridine flash-point in waste liquid is low, and easily produce blast, the method that therefore can not ignite with naked light, should adopt and under hot conditions, make its natural method.Pass through repetition test, when chamber temperature is during higher than 600 DEG C, waste liquid can completing combustion, considers the resistance to elevated temperatures of combustor material and the heat resistance of rear class flue gas processing device, the operating temperature of combustion chamber is set as 600-1000 DEG C by we, preferably 700 DEG C.
Because waste gas is sour gas, the solution taking up in cooling vessel 6 is dilute alkaline soln, the sodium hydroxide solution of preferred mass concentration 5%, and the solution taking up in exhaust-gas treatment container 7 is concentrated alkali solution, the sodium hydroxide solution of preferred mass concentration 33%.Filter by the interior dilute alkaline soln of cooling vessel 6, not only can reduce gas temperature, the dust granules material in all right filtering gas, prevents that it from stopping up smoke discharging pipe.By the concentrated alkali solution processing in exhaust-gas treatment container 7, can absorb the sour gas such as carbon dioxide in flue gas, nitrogen dioxide, sulfur dioxide, sulfur trioxide.
Waste liquid is relevant with sample size the burning time in Muffle furnace, and 10mL waste liquid all burns to be needed more than 2 minutes.Air capacity is relevant with component of effluent and sample size, and what we selected is the air pump of flow 30L/min, and 10mL waste liquid approximately needs 56L air.
If waste liquid karl-Fischer reagent waste liquid, its clean-burning condition
Combustible in waste liquid is mainly pyridine and methyl alcohol, and their clean-burning chemical equations in oxygen are as follows:
2C

By constituent analysis, in waste liquid, the volume ratio of pyridine and methyl alcohol is about 3:7, supposes to have waste liquid X(mL), while fully burning, need the content of oxygen to be
The volume that is converted into air under standard state is
0.05X×22.4×5=5.6X（L）
0.98,0.79 density (g/mL) that is respectively pyridine and methyl alcohol in formula, 79,32 are respectively their molal weight (g/mol), and 22.4 is the molal volume (L/mol) of gas under standard state.
Calculating above shows to make X(mL) the waste liquid required volume of air of fully burning is about 5.6X(L), because combustion furnace cavity volume is little, in chamber, air is not even enough to allow the waste liquid of 1mL fully burn, therefore need to use air pump to increase the intake of combustion furnace air, we have chosen the small size air air pump that a flow is 30L/min.Under the condition of 600 DEG C, add the waste liquid of different amounts to carry out repetition test, the concentration that detects gas in the flue gas producing that burns is observed the combustion case of waste liquid.
In the time that sample size is 10mL, the incineration of liquor time is about 2 minutes, and it is 5.6 × 10=56(L that waste liquid completing combustion needs volume of air), and the volume of air of air pump suction is about 30 × 2=60(L), substantially meet result of calculation.Therefore can determine fully burning of waste liquid when each sample size is 10mL, adjust on this basis different furnace temperatures to test, observe the combustion case of waste liquid.
Above-mentioned test shows, when chamber temperature is during higher than 700 DEG C, waste liquid can completing combustion, considers the resistance to elevated temperatures of combustor material and the heat resistance of rear class flue gas processing device, and the operating temperature of combustion furnace is set as 700 DEG C by we.
In addition, can also in the interior concentrated alkali solution of exhaust-gas treatment container 7, be added with acid-base indicator, for example phenolphthalein, when normal, NaOH solution takes on a red color, when alkali lye by sour gas completely in and time, it is colourless that solution is, and judges with this whether solution lost efficacy, so that in time with changing.
Adopt the method for high temeperature chemistry processing to process karl-Fischer reagent waste liquid, the noxious material in waste liquid changes into the gas of environmental sound after absorbing by processing, can directly enter atmosphere.Use aqueous slkali later substantially to become neutral, and the material that in solution, reaction generates is inorganic salts, can directly discharge after reconciling into neutrality by soda acid, can polluted water yet, therefore substantially can accomplish the harmless treatment of waste liquid, greatly reduce the pollution of waste liquid to environment.
The device of developing can effectively be processed karl-Fischer reagent waste liquid, not only can be applied in power industry, and can be adapted to the use such as oil, medicine karl-Fischer method and measure the field of micro-water, has wide promotion prospect.Can also process some common organic wastes, can be adapted to the refuse processing of chemical laboratory simultaneously.
