冷冻干燥平台的设计与仿真优化
Design and Simulation Optimization of Freeze-Drying Platform
摘要
Abstract
Aiming at the problems existing in the exploration of medium-high maturity shale oil formations that light hydrocarbon components are volatile at room temperature,while the existing closed freezing pyrolysis technology only supports single-sample processing,which is difficult to meet the demand for batch and rapid analysis at exploration well sites,a freeze-drying platform compatible with pyrolyzers was developed.It achieved refrigeration below-30.00℃and moist air isolation under stringent space constraints.Through finite element temperature-flow field simulation combined with experimental verification,the parameters of the platform's refrigeration,thermal insulation,and dry air curtain modules were optimized.Thermoelectric Coolers(TECs)were selected to achieve stable refrigeration at-30.00℃;the designed thermal insulation structure adopted 7.0 mm thick polyurethane insulation cotton,and the air jet structure and intake pressure were optimized to form a dry air curtain.The experimental results show that the platform's module parameters comply with space constraints,meet functional specifications,and enable batch sample processing.This study provides a stable low-temperature and dry environment for shale oil pyrolysis,thereby improving the accuracy of oil-bearing property evaluation,and also offers reference for the simulation optimization in the design of similar low-temperature equipment.关键词
