Research On Safe Operation Of Corrugated Tubes Exchanger In Device Of Crude Oil Stabilizing

Shell and tube heat exchangers are typical process equipments in petrochemical industries, and the corrugated tube heat exchanger is a new type of tubular heat exchanger. Corrugated tube has its unique advantages and characteristics, heat transfer coefficient tall, compact structure, but also has dirt-remover. It has been widely used since its after appearing. On the corrugated tube heat exchanger research are generally improved heat exchange research, there are few on the corrugated tube heat exchanger overall safety analysis.Throughout all kinds of domestic and foreign literature material, it is difficult to find safe operation corrugated tube heat exchanger and the analysis of cases. Meanwhile, the corrugated tube heat exchanger and overall safety hasn't been operation analysis.This article simply introduces several common abnormity double-sided strengthening pipe and characteristics. Mainly introduces the structure characteristics of the bellows tube,and the corrugated tube heat exchanger and make a simple improved heat transfer analysis.Then the corrugated tube heat exchanger temperature field analysis of the whole. First do these correctly: model building, mesh generation and loading of the temperature field. Then get the solution to temperature field. Finally, analyzing path results and summing up rules.Make analysis of corrugated tube heat exchanger for four operating conditions operation. Firstly make analyzed for separately corrugated tube, according to the analysis of the results of the corrugated tube test largest stress position, safe operation condition judgment. And in the case of overall modeling analysis, same tubesheet test safe operation condition judgment.In the end the corrugated tube heat exchanger, according to the material analysis materials, materials features simple characteristics of the material safety operation analysis, proposes the solution method.Through the corrugated tube heat exchanger and overall safety operation analysis found that the corrugated tube heat exchanger and safe operation is decided, including many aspects of material, structure, operation environment factors common decision. This equipment is mainly caused by failure of stress corrosion, and puts forward some suggestions.This paper from the aspects of the heat exchanger has research on the characteristics of the whole operation safety for future condition analysis, the corrugated tube heat exchanger and provides some references for safe operation analysis role.
