过硫酸盐生产中冷冻结晶工艺条件的优化和产品质量控制研究+CAD图纸(2)
Product quality or not, the development of chemical enterprises of great significance.This paper also studied the factors affecting the quality of ammonium persulfate products, including ammonium sulfate over management of raw materials, testing, management and testing of the finished product, management testing equipment, production technology and quality inspection standards and other intermediate goods.
This topic is ammonium persulfate Studies Department. By freezing ammonium persulfate crystallizer operation, process calculation of main equipment - mass balance, heat transfer calculation, design structure of the computing device.By the calculation that the raw material liquid solvent quantity 9917kg/h; feed flow 10779kg/h, the total heat transfer coefficient of 282.84 , the heat transfer area of 44.43 , the heat is320427.9 , heat capacity, so the use of the tray heat pipe system; mold diameter of 4 , a height of 10.10 , a volume of 127 .
According to the above ammonium persulfate crystals obtained important factors influencing the crystallization of ammonium persulfate, ammonium persulfate preliminary calculation of the crystallization processes and equipment for the optimization of ammonium persulfate freeze crystallization process provides a reference.
Because this design is based on data provided by the Shanghai Tiantan Auxiliaries Co., Ltd. carried out,And Shanghai Tiantan Auxiliaries Co., Ltd. mainly produces ammonium persulfate, potassium persulfate, sodium persulfateSo this design study aimed at discussing ammonium persulfate.
