摘要: 旋流式蒸汽混合撬是直接将蒸汽平稳地掺入需加热介质的设备,在掺入蒸汽的过程中有效避免了水击、需加热介质中杂质较快堵塞管道的问题,不考虑壳程损耗的情况下蒸汽利用率可达100%。本文主要展示了由于工业生产中原油加热脱水时遇到的问题,传统原油脱水加热方法采用物理换热法,即通过金属的热传导作用将温度较高热源介质的热量传递给温度较低的需加热介质,使温度较低的需加热介质达到升温的目的,此种方法设备综合热利用效率普遍低于80%,如果再考虑介质流速、导热材料结垢、介质纯净度等因素,综合热效率不足60%;作者等通过对这些问题的分析设计并制造出旋流式蒸汽混合撬;在设计的过程中首先考虑了水击问题和需加热介质易堵塞通道的问题,颠覆了传统的换热理念,通过对该设备的完善和优化,达到了较理想的效果,同时理论上模拟了不同加热温度的节能指标,以及在现场投入使用后的应用效果评价,认为该设备适用于目前的生产工况,可产生较高的经济效益。

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
