木材干燥是木材加工过程中能耗最大的工序,约占企业总能耗的50～70％,而且我国目前普遍采用的蒸汽干燥其能量利用率很低,大约30％左右。这种干燥方法能耗大的主要原因是进、排气的换气损失和干燥室壳体的散热损失大。它是利用蒸汽的热能加热空气,再送热空气去干燥木材,随着木材中水份的蒸发,空气的相对湿度加大,吸 Wood drying is the most energy-intensive process in wood processing, accounting for about 50-70% of the total energy consumption of the enterprise. And the energy utilization rate of steam drying commonly used in our country is very low, about 30%. The main reason for the energy consumption of this drying method is the loss of ventilation of the intake and exhaust and the heat loss of the housing of the drying chamber. It is the use of steam heat to heat air, send hot air to dry the wood, with the evaporation of moisture in the wood, the relative humidity of the air increases, the suction
