Abstract: Swirl type steam mixer is mixed directly to pry smoothly incorporated into steam heating medium in the process of mixing equipment,the steam to avoid water hammer,impurities heating medium fast block the pipe,without considering the utilization rate of 100% steam shell loss case.This paper mainly presents the industrial production of crude oil dehydration encountered the problem of traditional dehydration of crude oil heating method by physical heat transfer method,namely the high temperature heat source of the heat transfer medium to low temperature heating medium through the heat conduction of metal,to heat the low temperature medium,the equipment comprehensive heat utilization efficiency is generally lower than 80% in this way.If we consider the medium flow rate,heat conducting material fouling,medium purity and other factors,the comprehensive heat efficiency is less than 60%; we design through an analysis of these problems and create a swirl type steam mixer,consider water hammer problems and the heated medium clogging channel problems in this process and subvert the traditional concept of heat exchanger,achieve a more ideal effect through the improvement and optimization of the equipment.At the same time,the energy saving index of different heating temperature is simulated and the application effect after the field is evaluated.It is considered that the equipment is suitable for the current production condition and can produce high economic benefits.

Key words: water hammer, easy to plug, heat transfer mode, energy conservation
