夹套式高压釜装置
摘要：
本发明涉及一种具有外部加热组件的聚合高压釜，包括高压釜容器主体、高压釜入口、压力释放阀和加热导管。高压釜容器主体限定了在其内部可发生聚合反应的内部反应室。高压釜容器主体也为合金钢。加热导管围绕外表面的热传递部分并且与之相连。加热导管具有多个围绕高压釜容器主体的盘绕体使得加热流体可环形流经过加热导管以穿过热传递部分将热量传递到内部反应室。加热导管由铬钼合金钢制成。加热导管也与热传递部分相连以大体上避免源自于大于80℃的重复周期温度差异的低周期疲劳损坏。
摘要（英）：

A polymerization autoclave having an exterior heating assembly can include an autoclave vessel body, an autoclave inlet, a pressure release valve, and a heating conduit. The autoclave vessel body defines an interior reaction chamber within which a polymerization reaction can occur. The autoclave vessel body is also of a steel alloy. The heating conduit is wrapped around and attached to a heat transfer portion of the outer surface. The heating conduit has multiple wraps around the autoclave vessel body such that heating fluid can be circulated through the heating conduit to transfer heat into the interior reaction chamber across the heat transfer portion. The heating conduit is formed of a chromium-molybdenum steel alloy. The heating conduit is also attached to the heat transfer portion so as to substantially avoid low cycle fatigue damage from repeated cyclic temperature differentials greater than 80 DEG C.
