中文摘要：

为了提高旋风分离器在高温高压条件下的承压耐温能力,根据工业应用成熟的PV型高效旋风分离器的结构,提出一种长圆切向入口、两端封头的压力容器式旋风筒体旋风分离器（简称容器式旋风分离器）。流场模拟分析表明,在相同入口气速下,容器式旋风分离器外旋流区的切向速度明显高于PV型旋风分离器,且器壁附近向下的轴向速度也略高于后者,中心涡核区轴向速度低于后者。用中位粒径为9.8μm的滑石粉进行加尘冷模实验表明,相同气速下,容器式旋风分离器的分离效率较PV型旋风分离器的高约2%;相同压降下,前者的分离效率明显高于后者。容器式旋风分离器结构简单,结构强度和分离性能优良,可供高温、高压工况的分离操作使用。

英文摘要：

To improve resistance ability of the cyclone separator at high temperature and high pressure environments, based on the maturely applied PV type high efficiency cyclone technology, a new type cyclone, named as a pressure vessel type cyclone, with oval tangential inlet, shell cover on both ends and pressure vessel type cylinder, was put forward. The flow field simulation analysis indicated that the tangential velocity in the outer vortex region of the pressure vessel type cyclone was obviously higher than that of the PV type cyclone under the same inlet velocity, the axial velocity near the wall of the former was a little higher than that of the latter and the axial velocity inside the inner upward vortex region of the former was lower. The cold model test by using talc powders in median size of 9.8 μm showed that the separation efficiency of the pressure vessel type cyclone was approximately 20% higher than that of the PV type cyclone at the same velocity. Moreover, the separation efficiency of the pressure vessel type cyclone was higher than that of the PV type cyclone under the same pressure drop, meaning that the pressure vessel type cyclone with simple structure was good in both strength and separation performance, which could be applicable in the separation process under high temperature and pressure environments.
