Description
Можно предотвратить образование накипи на поверхност х нагрева выпарных аппаратов, если не допускать соприкосновени гор чей поверхности с увариваемым продуктом или жидкостью, наход щимис в некип щем состо нии. С этой целью предлагаетс склонные к образованию накипи продукты и жидкости доводить в выпарном аппарате до бурного кипени острым паром, подаваемым через барботер, после чего дать теплоноситель к поверхности нагрева, закрыть барботер и вести упаривание в обычном пор дке.It is possible to prevent the formation of scale on the heating surfaces of the evaporators by preventing contact of the hot surface with the product or liquid being boiled or in non boiling state. To this end, it is proposed to incinerate products and liquids in the evaporator to boil with live steam supplied through a bubbler, then give the heat carrier to the heating surface, close the bubbler and evaporate in the usual order.
Если жидкость доведена до бурного кипени , то исключаетс возможность местного ее перегрева, в результате которого образуетс накипь (обугливание или осаждение солей) на поверхност х нагрева. Происходит интенсивное перемешивание упариваемого раствора, и местного перегрева не наблюдаетс .If the liquid is brought to rapid boiling, then the possibility of its local overheating is excluded, as a result of which scale formation (charring or sedimentation of salts) on heating surfaces is formed. Vigorous stirring of the evaporated solution occurs, and no local overheating is observed.
В цел х предотвращени образовани накипи в конце упаривани предлагаетс непосредственно перед прекращением подачи теплоносител к поверхности нагреЬа впускать в упаренный продукт пар через барботер (дл поддержани циркул ции продукта), затем выключать из работы поверхность нагрева, а подачу пара через барботер прекращать по охлаждении поверхности нагрева до температуры, близкой к температуре упаренной жидкости в аппарате.In order to prevent scale formation at the end of evaporation, it is suggested immediately before stopping the supply of heat transfer medium to the heating surface to let steam into the evaporated product through the bubbler (to maintain product circulation), then shut off the heating surface from operation, and stop the flow of steam through the bubbler after cooling the heating surface to a temperature close to the temperature of the evaporated liquid in the apparatus.
В случае, если в процессе упаривани производитс долив жидкости в аппарат, то она должна быть подогрета вне аппарата до температуры , исключающей возможность снижени интенсивности кипени увариваемой в аппарате жидкости. Барботер, устанавливаемый в нижней части аппарата, должен быть сконструирован и смонтирован так, чтобы он обеспечивал бурное кипение жидкости, обмывающей поверхности нагрева аппарата.In the event that topping up the liquid into the apparatus is carried out during the evaporation process, it should be heated outside the apparatus to a temperature that excludes the possibility of reducing the boiling intensity of the liquid boiled in the apparatus. The bubbler, installed in the lower part of the apparatus, must be designed and mounted so that it provides rapid boiling of the liquid washing the heating surfaces of the apparatus.
