Abstract
Due to the loosening and falling off of the "kiln skin" and refractory bricks on the inner wall of the rotary kiln barrel, the temperature in a certain area will rise rapidly, forming a hot spot. In severe cases, the kiln will be shut down. Therefore, the hot-spot water cooling technology of the rotary kiln barrel is studied to provide precise and controllable water mist cooling of the hot-spot area to reduce thermal bending deformation caused by circumferential temperature differences and reduce the damage to the "kiln skin" and refractory bricks, extend kiln operation time. An optimized PID control method is used to control the cooling rate. Simulation and simulation experiments show that this method can reasonably cool the temperature of the hot spot area to the set temperature.
