换热器全逆流与交叉逆流在操作中的实际应用

The application of heat exchanger full counter-flow and cross counter-flow on practical operation

为了解决解吸水解系统废水排放不合格、解吸系统严重带液等现象,分别从两种不同换热流程来阐述在工艺操作中的实际应用效果,结果表明完全逆流换热效果比交叉逆流换热效果明显、经济价值可观、系统操作更优化。

To solve the problem of that waste water discharge was not qualified, stripper with liquid seriously in stripper hydrolyzing system, the practical effect of 2 different kinds of heat exchanger flow path was expounded. The results shown that effect of full counter - flow was significantly better than cross counter - flow, economic value con- siderable, operation system more optimized.
