通风管道过滤器微波灭菌系统的灭菌性能预测OA

Aiming at the complexity of the microwave disinfection process,a temperature-based predictive method for disinfection performance was proposed.First,a temperature rise characteristics numerical model of the composite filter under micro wave field was established to obtain its heating process.Then,by combining the relationship model between disinfection rate and temperature,the disinfection performance of the ventilation duct filter micro wave disinfection system was predicted.Finally,the validity and accuracy of the numerical model were verified based on the experimental data.Results show that when the microwave power is 600 W and 400 W,the average absolute errors between the simulated and measured final steady-state temperatures at each measurement point on the composite filter are 0.9℃ and 2.4℃,respectively,and the average absolute errors of the predicted disinfection rates from simulated and measured temperatures are 0.2％and 1.2％,respectively.The established numerical model demonstrates high simulation accuracy for the temperature rise process of the composite filter under microwave field,thereby enabling reliable prediction of the microwave disinfection performance of ventilation duct filters.
