热风式浆纱机或联合式烘房浆纱机在烘干湿浆纱过程中,有大量水份蒸发到循环热风中。为了不使循环热风的含湿度增加以至降低蒸发速度,设置了排湿风机,不断排出含湿量高、温度也高的湿热空气,同时,由其他风机从外面不断补入含湿量小、温度较低的补给风。一台普通热风浆纱机每小时排 Hot air sizing machine or combined drying room sizing machine in the process of drying wet sizing, a large amount of water evaporated into the circulating hot air. In order not to increase the humidity of the circulating hot air and even reduce the evaporation rate, a dehumidifier blower is set up to continuously discharge hot and humid air with high moisture content and high temperature. At the same time, Lower supply wind. An ordinary hot air sizing machine row every hour
