Background
The main components of the desulfurized gypsum are the same as natural gypsum, the desulfurized gypsum is a byproduct of an FGD process, and the FGD process is a technology for recovering sulfur dioxide in flue gas of coal or oil by using lime-limestone and is widely applied to industries such as building materials and the like.
With the continuous development of society, the desulfurized gypsum generated by flue gas desulfurization of thermal power plants is increased year by year, and the desulfurized gypsum has high viscosity and is extremely inconvenient to ship, thereby bringing difficulty to further utilization. Because the desulfurized gypsum has small particles and is dried quickly, crystal form generated at 105 ℃ is converted into semi-hydrated gypsum, and the drying temperature of the desulfurized gypsum is not required to be very high. At present, a hot gas direct contact method is mostly adopted in a drying method, such as equipment and processes of a rotary dryer and the like, wet-based desulfurized gypsum is sent into a high-efficiency rotary dryer through a double-screw feeder and a rubber belt conveyor for drying, physical water is removed, the dryer adopts high-temperature smoke gas as a heat source, and waste gas discharged from the dryer is subjected to dust collection through a high-temperature gas box pulse bag type dust collector and then is discharged after reaching standards. This kind of drying technique is difficult to make the inside steam of material dry to the stoving of material, and along with the stoving of desulfurization gypsum, moisture content diminishes, a large amount of dry desulfurization gypsum get into waste gas and form the gas-solid phase and discharge, and the dust concentration in the waste gas is high, brings the degree of difficulty to the processing of waste gas, leads to causing negative effects to the atmospheric environment, also increases the manufacturing cost of enterprise simultaneously, and when drying, the lotion adhesion appears on the stoving bucket lateral wall easily, the condition that is difficult to the clearance.
