According to the design of the scale of production, of neutralization tank, the alkali prepared tank, dispersion medium mixing tank, polymerization reaction kettle of the material balance and finishing, obtained in various stages of production process in the process of input and output, the ratio of raw materials and corresponding quality. Also in order to select the optimum operation conditions, develop both economic and reasonable energy consumption scheme, of complex alkali process and neutralization process, polymerization reaction process the input heat and output of heat were heat balance. Finally, we have carried out the calculation and selection of the main equipment, including the height of each kettle, the determination of inner diameter, the size of the jacket, and the separation and drying equipment.. Through investigation, the main types and manufacturers of process equipment and accessories are determined..
According to an annual output of 4000 tons of sodium polyacrylate process design of the
layout design of the workshop, the design workshop features higher monolayer design, and using easy installation and disassembly mobile operating platform steel instead of concrete operation table can better meet the process. This design also takes into account the environmental protection aspects.. In the production process, the waste water and the noise emissions are strict requirements. This design scale for the annual production of sodium polyacrylate 4000 tons, according to the annual 2 days, every day 8 classes, a class of 330 hours of production, a class can produce two batches, each batch of output is 3030.30kg.
This design by the teacher Xu Chunhua, in the whole process design process many teachers made a lot of valuable comments, in this express heartfelt thanks. Through the whole design process of the system training, I have a comprehensive understanding of the production process and application of sodium polyacrylate, which will lay the foundation for the future work.. Because of wide knowledge of polyacrylic acid sodium production process design, and my limited knowledge and experience of, design errors and inappropriate, ask examines teacher criticism and corrections.
KeyWords: Sodium polyacrylate; industrial design; material balance; heat balance; equipment selection
