摘　　要：植物油浸出车间产生的含正己烷废气,一般采用冷凝和矿物油吸收后排放。随着环保要求的提高,尾气处理采用光催化、冷冻法、燃烧法等多种方法进行处理。近期树脂吸附法被证明高效,得益于树脂有较大的比表面积大、孔容大、疏水性好、稳定性强、使用安全性高、使用周期长等优点。通过连续的吸附脱附工作将废气中的正己烷进行回收,可控制尾气中VOCs低于30 mg/m^(3),优于排放标准。The exhaust gas containing n-hexane generated in vegetable oil extraction workshop,is generally discharged after condensation and mineral oil absorption.As the improvement of environmental protection requirements,many exhaust gas treatment approaches are developed,such as photocatalysis,refrigerated absorption and combustion.Recently,resin absorption is proved to be effective benefits from its high specific surface area,large porosity,good hydrophobicity,strong stability,high safety and long service life.By continuous adsorption and desorption,n-hexane containing in the exhaust gas can be recovered,and the volatile organic compounds(VOCs)in the exhaust gas can be controlled to be below 30 mg/m^(3),which is better than the emission standard.
