Modelling of heat transfer processes in film liquid devices
when obtaining fresh water
Abstract: The scheme of a desalination plant is presented in which it is proposed to use the process of evaporation and condensation of moisture in the air (the SCWF process) which moves along a closed contour to produce fresh water. The principle of operation of the installation is based on the property of air to sharply increase its maximum moisture content with increasing temperature. If the temperature is lowered by 30–40 deg. it is possible to obtain up to 520 kg per hour of fresh water. The intensity of evaporation of moisture is determined by the temperature of the wet thermometer. In the present work, an experimental study of heat exchange and the length of the economiser portion of the water film is performed, i.e. the area where the water is heated to the temperature of a wet thermometer. In experimental studies, data were obtained on the changes in air and water film temperatures as well as on the relative and absolute humidity of air along the contact length, and generalisation of the obtained data on heat transfer as criterion dependence was made.
Key words: desalination plant, maximum moisture content, condensation, water film, heat exchange, relative and absolute humidity, water heating.
