Abstract

The invention provides a quick aging device for semi-hydrated calcined gypsum powder. The quick aging device comprises a shell and a weighing device arranged below the shell, the shell is provided with a sealed chamber and a stirring device for stirring gypsum powder; the shell is provided with a dry air inlet allowing dry air to enter the sealed chamber, a water vapor inlet allowing water vapor to enter the sealed chamber, and a material hole allowing materials to enter and exit. The device further comprises a temperature control device which is used for regulating and controlling the temperature of the sealed chamber, and a humid air exhaust pipe which is detachably connected with the material hole. The desulfurized gypsum powder is put into the sealed chamber, the dry air inlet and thematerial hole are opened, and the desulfurized gypsum powder in the sealed chamber is heated through the temperature control device to dehydrate the desulfurized gypsum to form anhydrous gypsum; thenthe temperature in the sealed chamber is reduced, the dry air inlet and the material hole are closed, the water vapor inlet is opened, water vapor is slowly introduced, and meanwhile, the stirring device is opened so that the anhydrous gypsum and the water are quickly and fully mixed to form alpha-type semi-hydrated gypsum.

Description

technical field [0001] The invention relates to the technical field of gypsum materials, in particular to a rapid aging device for hemihydrate calcined gypsum powder. Background technique [0002] Gypsum plays an important role in our industrial production, and it can be mainly divided into two categories: natural gypsum and desulfurized gypsum. In order to effectively implement the policy of energy saving and emission reduction, the construction of flue gas desulfurization gypsum equipment in coal-fired power plants has been developed rapidly. Among them, the desulfurization gypsum is made of lime-limestone powder and water to make a slurry, which is used as an absorbent and pumped into the absorption tower to fully contact and mix with the flue gas. The sulfur dioxide in the flue gas, the calcium hydroxide in the slurry and the air blown in from the lower part of the tower Oxidation reaction generates calcium sulfate and calcium sulfite. Among them, the content of dihydr...
