METHODS OF STRUGGLE AGAINST ADJOURNMENTS ON HEAT-EXCHANGE SURFACES OF THE DEVICES, APPLIED FOR EVAPORATION OF PHOSPHORIC ACID
In article the analysis of the existing problems, complicating conducting of process of evaporation of wet-process phosphoric acid, and also the factors influencing its efficiency is carried out. The special attention is given the processes, directed on struggle with buildups of salts on heating elements of evaporating devices. Unfortunately, completely to prevent process of formation of buildups on heat-exchange surfaces at evaporation now it is not possible. It is necessary to clear walls of the heat-transmitting equipment of the formed incrustations periodically. The review of patent and literary sources on the given subjects (both domestic, and foreign authors) is resulted. Recommendations about application of the most rational methods of decrease in speed of adjournment and increase of efficiency of clearing of heat-exchange surfaces of devices are made.
