Why does lime gypsum method desulfurization bubble

Why does lime gypsum method desulfurization bubble

Answer:

Bubble is a very common problem, the reason is more, there are several reasons:1 the boiler in the operation of the oil, combustion is not sufficient, unburned components with the boiler flue gas into the absorption tower, resulting in the absorption tower organic matter content increased;2 the dust collector in the rear of the boiler is not in good condition, and the concentration of flue gas dust is excessive, and the impurities in the absorption tower slurry are increased after the impurities containing a large amount of inert substances enter the absorber. The increase of heavy metal ions leads to the increase of the surface tension of slurry, which makes the surface of slurry bubble;
The dehydration system or waste water treatment system can not be put into normal operation, which makes the quality of absorption tower gradually deteriorate;5 the boiler combustion is not good, fly ash in some carbon particles or tar with smoke into the absorption tower;6 in the course of operation, the phenomenon of the sudden trip of the oxidation fan suddenly appeared, and the gas-liquid equilibrium of the absorption tower was destroyed, resulting in a large amount of overflow of the absorber.
The limestone contains excessive MgO (foaming agent), and the reaction of sulfuric acid with a large number of foam (foam fire extinguisher is the use of this principle);
