Control method for improving quality of calcined gypsum prepared from desulfurization gypsum based on temperature and humidity

The invention discloses a control method for improving quality of calcined gypsum prepared from desulfurization gypsum based on temperature and humidity. The method comprises the following steps: S100, performing warm kiln protection, starting a rotary kiln, and opening a main steam valve; S200, temperature detecting and feeding, namely detecting the outlet temperature of the rotary kiln by a temperature detection device, and starting raw gypsum feeding equipment to feed when the temperature reaches 160 DEG C; S300, temperature control, namely starting an automatic temperature control system within a period of time after feeding, regulating the opening of the main steam valve according to the temperature detected by the temperature detection device, and automatically controlling the internal temperature of the whole rotary kiln; S400, humidity detection and judgment, namely detecting the humidity of a space inside the rotary kiln and judging the humidity variation trend by a humidity detection device, and adj
