Why is the gypsum produced by the lime-gypsum desulfurization method not in solid form, but rather in a thin paste-like state?

Hello. How to detect the oxidation effect. We just have a gas explosion tank. A large amount of oxygen is introduced. I’m not sure how to judge the effect.
Hello, is there a significant difference when using limestone powder and quicklime powder? Different calcium oxide contents
Find a laboratory and ask about the methods for testing SO4+ and SO3+ in gypsum； And then test your products again ； It should be possible to find out ；
What does that mean? Limestone powder is CaCO3, while quicklime is CaO; both can be used for desulfurization, but their processes differ greatly, and their operating costs are also different ；
I’m confused; I’ll reply first to your other post, where it says that the filter press products don’t take shape. So you mean the gypsum products don’t take shape. It is recommended to consider the following aspects: 1. The vacuum belt conveyor equipment itself: Pay special attention to the vacuum level ； 2. Slurry moisture content from the cyclone station to the belt conveyor ； Check the operating status of the swirl station ； 3. Oxidation effect in the absorber slurry tank: Try increasing the amount of oxidizing air ； 4. Check whether the host is burning oil: An increase in the oil content in the slurry may cause the filter cloth of the belt conveyor to become clogged ； 5. The pH value, density of the absorption tower, as well as the dust content in the flue gas – all of these factors have an impact on the moisture content of the filter cake. I hope this helps you
