摘要
低温甲醇洗工艺中换热器是至关重要的设备,绕管式换热器作为一种新型的高压换热设备,比传统的换热器单位体积的传热面积更大,结构紧凑,能在较小的温差下提供多种介质的换热,传热系数高,节约空间,效率较高,但在使用中因为管子密度大且是环绕的,所以应用中也存在一些问题,绕管式换热器多用于煤化工中的空分、净化、煤制油等工艺中。
The heat exchanger in low temperature methanol washing process is an essential equipment, tube type heatexchanger is a new type of high pressure heat exchanger equipment, it has more heat transfer area than traditional heatexchanger, changing the traditional compact structure, can provide heat for a varietydifference, with high heat transfer coefficient, space saving and high efficiency, butapplication because the pipe is high density and surrounded. The tube heat exchanger ispurification of coal chemical industry and coal oil production process
