The possibility of developing a apparatus based on the results of kinetic calculations of the processes, occurring in it, is considered. The studies were carried out with the system solid-liquid-vapor-gas medium with a continuous increase in vacuum above the surface of a layer of the dispersed material. The presence of the liquid phase and the vapor-gas phase in equilibrium with it makes it possible to provide a change in concentration, structure, or cooling in the system due to artificial disturbance of the dynamic equilibrium of the system. To develop a mathematical model of the liquid removal process, a model of ideal mixing in the vapor-gas phase and a layer of the dispersed material was adopted. The calculation results are presented in the form of kinetic dependences of the main process parameters. Calculation of the apparatus is carried out at the highest load in the vapor-gas phase during the period of removal of the free moisture. In this case, the influence of rarefaction on the physical characteristics of the removed fluids and the design features of the apparatus being calculated was taken into account.

基于蒸汽-气体介质减压从固体材料中去除液体过程的动力学计算数据的装置开发

考虑了基于其中发生的过程的动力学计算结果开发设备的可能性。这些研究是在系统固-液-气-气介质中进行的,在分散材料层表面上方的真空度不断增加。由于系统动态平衡的人为干扰,液相和与其平衡的汽-气相的存在使得有可能在系统中提供浓度、结构或冷却的变化。为了建立液体去除过程的数学模型,采用了汽-气相中理想混合和分散材料层的模型。计算结果以主要工艺参数的动力学依赖性的形式呈现。设备的计算是在去除游离水分期间在气相中的最高负荷下进行的。在这种情况下,稀疏对去除流体的物理特性的影响以及被计算设备的设计特征都被考虑在内。
