废水蒸发器环形管板的分析设计

Analytical Design of Annular Tubesheet in Waste Water Evaporator

高温气冷堆示范工程液废处理系统废水蒸发器管板是中间大开孔的环形管板,其设计计算已超GB/T 151—2014常规设计标准的规定。对这种环形管板的设计进行了研究,并采用有限元法对该管板进行计算与分析,进而对其安全性进行了验证。

The tubesheet for waste water evaporator in High Temperature Reactor Pebble Module(HTR-PM)is annular one with a large opening in the center.The design and calculation of annular tubesheet is beyond the applicable scope of GB/T 151-2014.In this paper,the design method for annular tubesheet was studied first,and then by using finite element method the tubesheet was calculated and analyzed,so that the safety of the tubesheet was verified.
