吸附式和冷冻式空气净化装置选型比较

Type selection between the adsorption and freezing dehumidifier

结合本公司 6万t聚酯工程设备选型对两种净化装置进行了性能经济比较。冷冻式运行费用低 ,体积小、重量轻、占地少 ,安装使用维护方便 ,露点稳定 ,工作时间长 ,能量可随介质相对温度变化自动调节。致命弱点是露点温度不能要求太低 ,否则将会结冰 ,导致整个系统报废。另外还受环境温度的影响。为满足本工艺的要求 ,露点为 -4 0℃的选吸附式 ,露点为 -2 5℃和

Combine with the equipment type selection of 60 kt polyester engineering in Jindi Company,the two types cleaning plant are comparied in properties and ecnomic.The freeaing dehumidifier has many advantages such as the operation cost is low,the volume is small,the weight is light,the occupation is little,the installation,using and maintenance is convenient, the dew point is steady,the working time is long and the energy can be automatic adjusted by the change of medium relative humidity.The weakness is that the dew point temperature has to be lower ,otherwise it can be freeze,the whole system is scrapped.To fit for the request of process, the adsorption type is selected at the dew point -40 ℃, the freezing type is selected at the dew point -25 ℃～-15 ℃.
