整個設備可分為加熱蒸發(fā)室、加熱夾套、汽液分離器、攪拌器等四部分。在夾套加熱的基礎上經多方面研究，設計了內加熱、內循環(huán)加熱，蒸發(fā)結晶鍋，用戶使用后反映其蒸發(fā)效果比外加熱〔夾套加熱〕高。
該設備與產品有接觸部分，采用1Cr18Ni9Ti制作，加熱蒸發(fā)室、如一園筒殼體，為按裝維修方便，采用不同厚度材料分兩段加工，用法蘭連接。封底可加工成半球形、碟形或錐形器身上，下圓筒都裝有視鏡，以觀察溶液沸騰狀況，霧沫夾帶高度，溶液的濃度，結晶大小及分布情況等；鍋休內入孔是為方便清洗、維修、下鍋部份焊上加熱夾套，其高度通過計算蒸發(fā)所需面積而定。
攪伴目前多采用錨式攪伴器轉速6一15轉/分，攪伴的按裝目前采用下軸安裝，可縮短軸長度，便于安裝維修。 |

This equipment is composed by four parts: evaporation room, heating jacket, vapor-liquid separator and stirring device. Our factory has made a lot of research based on jacket heating and designed the internal heating, internal circulating heating, evaporation and crystallizing pan. The users all think the evaporation result is 1.8 times than external heating (jacket heating).
All the parts that may contact with the product are made of 1Cr18Ni9Ti. The heating & evaporation room is like a cylinder shell body. In order to make repairing more convenient, materials of different thickness are used to process in two sections which are connected by the flange. The sealing bottom can be processed into hemispheric shape, dish ship and cone shape. The lower cylinder is installed with viewing mirror to observe boiling condition of the solution, entrainment height, solution concentration, crystallization dimension and distribution condition. Opening inside the boiler body is for easy cleaning and maintenance. Heating jacket is welded on lower boiler part of which the height is determined based on calculated area necessary for evaporation.
Anchored type stirring device with rotation speed of 6-15 rotations/min is used for stirring purpose. Lower-shaft installation method is adopted which may shorten shaft length and makes it easier for installation and maintenance.
