Calculation Model of Liquid Chlorine Evaporator of Drinking Water Disinfection System

The calculation model of the liquid chlorine evaporator for the drinking water disinfection system (chlorinator) was developed, based on the solution of the system of criterion equations of convective heat and mass exchange and heat transfer, describing two stages of the evaporator working process – evaporation of liquid chlorine and superheating of the obtained vapors. It is noted that the existing normative methods of calculation of chlorinator evaporators are outdated and do not fully take into account the heat and mass exchange processes occurring in them. A good match was found when comparing the calculated parameters of the evaporator with those of the prototype. It is concluded that the developed methodology can be used in calculation and design of chlorinators of different capacity.
