精馏型油分离器的仿真与实验研究
The simulation and experimental study of a distillation-type oil separator
摘要
Abstract
Aiming at the problem that the oil separation coefficient of oil separator is insufficient,in order to ensure the stable operation of auto cascade refrigeration system,a distillation-type oil separator was proposed according to the separation principle of traditional oil separator and distillation principle.Software Aspen was used to simulate the separation of R134a and PAG mixture in the distillation-type oil separator with an inlet temperature of 62℃and mass ratio of 9:1.An experimental device was established to test the efficiency of the distillation-type oil separator under different working conditions.The results show that the separation efficiency increases first and then decreases with the increase of mass flow rate of refrigerant under constant top heat transfer.When the mass flow rate of refrigerant is constant,the separation efficiency increases with the increase of heat transfer at the top.The experimental results are consistent with the simulation results.When the mass flow of refrigerant is 9.19g/?s and top heat transfer is 200W,the separation efficiency is up to 99.928%.Compared with traditional oil separator,the oil separation efficiency of distillation-type oil separator is significantly improved.关键词
