The wood dryer plays an important role in the wood processing industry, and this kind of equipment consumes a lot of energy and will waste energy. However, as long as we take appropriate reduction measures, it will be saved. The following will teach you how to reduce the energy consumption of the equipment. : Generally speaking, the energy consumption of a convection dryer is mainly composed of two parts, evaporating moisture and exhaust gas, and the latter part accounts for about 15% to 40%, and some are as high as 6%. ten.
Reducing the temperature of the exhaust gas at the outlet of the drying equipment is hindered by two factors: ensuring the moisture content of the product, the temperature of the exhaust gas at the outlet is too low, the moisture content of the product increases, and the required moisture content of the product cannot be reached. When the exhaust gas enters the cyclone separator or bag filter, ensure that its temperature is 20-60°C higher than the dew point.
Reduce heat loss during the drying process; generally speaking, the heat loss of the dryer will not exceed 10%, and if the large and medium-sized production equipment is properly insulated, the heat loss will be about 5%. Therefore, the insulation work of the drying system should be done well, but it is not that the thicker the insulation layer, the better, and a thickness of the insulation layer should be determined.
In order to prevent the leakage of the drying system, the blower and the induced draft fan are generally used in series, and the system is operated in a zero-pressure state after reasonable adjustment, so as to avoid the drying caused by the leakage of the drying medium or the leakage of the ambient air in the convection dryer. Decreased thermal efficiency of the machine.
