Raise the temperature of the tower of the Milk spary drying equipment
Increasing the temperature of the inlet tower of the hot air of the Milk spary drying equipment Under the condition that the outlet temperature is constant, the higher the inlet temperature of the hot air (also known as the inlet air temperature), the higher the total heat brought in, and the hot air per unit mass is transferred to the mud mist The more heat is dropped, the more water is evaporated per unit of hot air. In the case of a constant production capacity of the drying equipment, the amount of hot air required is reduced (that is, the heat taken away by the hot air when it leaves the tower is reduced), which reduces the heat consumption of the spray dryer powder drying and improves the utilization rate of hot air. And thermal efficiency. However, the temperature of the hot air entering the tower should not be too high (no more than 600 ℃), if the temperature is too high, it will burn out the air distributor on the top of the tower. Reduce the temperature of the hot air outlet tower.In the case of a certain temperature of the hot air inlet tower, the lower the temperature of the hot air outlet tower, the greater the temperature difference between the drying equipment and the tower, and the greater the heat transfer from the hot air to the mud for drying, so the hot air utilization rate The higher. However, the temperature of the exhaust air should not be too low. When the temperature is lower than 75℃, the powder is too wet, which affects the normal drying.
