| 为研究粒径、开方面风速和热源温度对气溶胶在通风柜内沉积率和逸出率的影响,本文以粒径为1 μm、2.5 μm、5 μm和8 μm的气溶胶为实验材料,通风柜开放面风速分别取0.5 m/s和1 m/s,热源温度分别为300 K、523 K和753 K,进行实验研究.实验结果表明,气溶胶在通风柜内的沉积率和逸出率与粒径、开放面风速以及热源温度有关,其中:1)在1 μm～8 μm内,随着气溶胶粒子粒径的增大,气溶胶粒子在通风柜中的沉积率升高,逸出率降低；2)当开放面风速由0.5 m/s增加到1 m/s时,气溶胶粒子的沉积率和逸出率均降低；3)在300 K～753 K内,随着热源温度的升高,气溶胶粒子的沉积率降低,而气溶胶的逸出率随之升高. |

| To explore the influence of particle size,operating area wind speed and heat source temperature on aerosol deposition rate and escape rate in fume hood,this article takes the aerosol of 1μm,2.5 μm,5 μm and 8 μm as experimental material with the operating area wind speed of 0.5 m/s and 1 m/s and heat source temperature of 300 K,523 K and 753 K.The results of experiments indicate that,operating area wind speed,particle size and heat source temperature have a certain correlation with aerosol deposition rate and escape rate in fume hood:1)within 1μm～8μm,the aerosol deposition rate increases with the increase of particle size,but the aerosol escape rate is on the contrary;2)as operating area wind speed increases from 0.5 m/s to 1 m/s,both aerosol deposition rate and escape rate decrease;3)within 300 K～753 K,the aerosol deposition rate decrease with the increase of heat source temperature,but the aerosol escape rate is on the contrary. |
