In order to improve the energy efficiency of the spray dryer, based on a full study of its performance, some effective energy saving and consumption reduction measures are summarized.

The first is to increase the temperature of the hot air entering the tower. With the temperature unchanged from the tower, the higher the temperature of the hot air entering the tower, the more heat is transferred to the mud droplets, and the more water is evaporated per unit of hot air. With constant production capacity, the amount of hot air required is reduced. In other words, this can reduce heat loss, and thus reduce the heat consumption of the spray dryer.

Secondly, the temperature of the hot air leaving the tower can be appropriately reduced. Under the condition that the temperature of the hot air entering the tower is constant, reducing the temperature of the hot air leaving the tower can reduce the heat taken away by the hot air from the tower, and can make maximum use of the heat of the hot air. To dry the mud droplets.

The third is to increase the temperature difference between the hot air entering the tower and the hot air leaving the tower. By increasing the temperature of the hot air entering the tower or reducing the temperature of the hot air leaving the tower, increasing the temperature difference between the hot air entering the tower and the hot air leaving the tower, making full use of the hot The heat of the evaporates the water content of the mist droplets in order to improve the thermal efficiency of the spray drying tower and reduce the energy consumption.

The fourth point is that the production efficiency of the spray dryer can be improved by reducing the moisture content of the ceramic slurry. In fact, the ceramic slurry has good fluidity and is easy to atomize, which can effectively shorten the spray drying time. Adding a suitable water reducing agent to the ceramic slurry can reduce the water content of the slurry.

Fifth, the temperature of the mud can be appropriately raised, which can reduce the annual rate, thereby improving the atomization effect of the spray dryer and reducing the heat consumption of spray drying powder.

The sixth point is the hot air in the separation tower of the recycling unit to reduce thermal energy loss.

The seventh point is the use of heat exchangers to recover waste gas waste heat, thereby significantly saving energy. In other words, during the use of the spray dryer, the heat exchanger will be able to make fuller use of heat, thereby increasing the atomization efficiency of the spray dryer and reducing energy consumption.
