Exhaust gas recycling of Stainless Steel Milk Powder Spray Dryer
Recycling of hot air (exhaust gas) from the tower after spray drying and pulverization of ceramic mud. If the hot air from the tower is directly discharged into the atmosphere, this part of heat loss will be considerable (about 10-20% of the energy consumption in the milling process). Therefore, this part of the residual heat should be fully utilized, for example, the hot air from the tower can be recycled to the preheating and drying process. In addition to the direct recycling of hot air out of the tower, this part of waste heat can also be stored or exchanged by a heat exchanger before reuse. Overall sealed control. Because the system uses negative pressure operation, if there is air leakage, it will increase energy consumption.Therefore, the thermocouple jacks of the hot air furnace, hot air pipe, exhaust pipe, and the tower body on each part of the equipment and the connection flange The negative pressure measuring hole, the discharge port of the lower cone of the tower, the discharge port of the cyclone dust collector, and other parts should be sealed well, and no air leakage is allowed.
