降低片碱生产过程中的碱损耗

Reduce the alkali loss in the process of flake production

采用三效逆流降膜工艺生产99%片碱,可有效利用蒸汽传热过程中产生的二次蒸汽,实现热能的综合回收,降低能耗。通过对该工艺环节的系统性分析,提出切实可行的解决措施,并将废碱合理地回收利用,既可减少对环境的污染,又节约了生产成本。

The three-effect counter-current falling film technology is adopted to produce 99% flake alkali,which can effectively utilize the secondary steam generated in the process of steam heat transfer to realize the comprehensive recovery of heat energy and reduce energy consumption.Based on the systematic analysis of the process,feasible solutions are put forward,and the waste alkali is reasonably recovered and reused,which can not only reduce the pollution to the environment,but also save the production cost.
