Description

一种减压系统的温度控制设备
本申请要求于2018年08月16日提交中国专利局的申请号为201810935200.4、发明名称为“一种减压系统的温度控制设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明属于煤化工与石油化工设备技术领域，具体涉及一种减压系统的温度控制设备。
背景技术
减压系统用于非固定床加氢装置中300～600℃高温及10～30MPa压力的恶劣工况下多相流介质的压力及流量调节，在减压系统投用前需要进行升温热备，避免高温介质直接进入管线引起管道或设备损坏；在投用后，为了便于快速检修，又需要进行合理速率的降温，以节省检修时间。
现阶段，由于温度和压力的苛刻条件，管线升温热备多采用直接在管线表面进行电加热的方案。但是电加热方案易引起管线外壁局部高温，加速管道及设备材料氧化；电加热的不均匀性也会造成管道应力不均，引起材料晶内/晶间析出、沿晶开裂等现象，并最终产生裂纹，加速管道材料失效。同时，电加热方案在检修时只能采用耗时的空冷方法，或者额外配置冷却系统增加设备造价。
此外，也有一些方案采用介于常温和工况温度之间的单一温度的热油媒介进行管线的温度控制。然而当工况温度较高时，单一温度的热油媒介与管线间的温度差能达到100～300℃，仍会引起管线材料的激冷激热，大幅降低管线寿命。
