Heat accumulation issue in empty tower cyclic spraying

Thread Content

The empty tower is sprayed with deionized water in a circulating manner; the air intake rate is approximately 10,000 cubic meters per hour at 80°C. (The process involves gas entering the spray tower, flowing through the circulation tank at the bottom of the tower, and then being pumped back for recycling via a circulation pump.) ) Consider only the issue of heat. (Now considering an inlet water temperature of 30°C) I would like to ask how, during design, it is possible to ensure that the heat in the circulating spray water does not accumulate, thereby preventing the heat from being removed. Is it by ensuring that the temperature difference between the inlet water temperature and the outlet water temperature does not exceed a certain value? How can the accumulated heat be removed? I would like to ask the experienced masters.
