It can be used as a cement retarder, gypsum building products, model making, medical food additives, sulfuric acid production, paper filler and paint filler, etc. The microporous structure and heating dehydration properties of gypsum and its products give them excellent sound insulation, heat insulation and fire resistance.

[0003] At present, lime slurry enters the desulfurization tower, reacts with sulfur dioxide in the flue gas through nozzle atomization, and finally forms gypsum. The current wet desulfurization process is mature, but sometimes the slurry in the absorption tower cannot be discharged normally due to foaming, causing the slurry density to gradually increase. One of the common problems that the liquid level is difficult to control is that the desulfurization effect is deteriorated, resulting in the outlet sulfur dioxide emission concentration exceeding the standard, which not only affects the production of the enterprise, but also damages the environment. Therefore, it is necessary to provide a defoaming treatment equipment for gypsum slurry preparation to solve the above technical problems. Utility Model Content
