| 中文摘要: |
| 油脂加工厂臭味气体包括油脂氧化生成小分子物质及豆腥味气体，浸出车间因正己烷、油脂和豆粕在生产过程中产生各种气味，精炼和污水处理中的油脂和化学剂等接触氧化产生臭味气体，小品种油料浓香油机榨车间产生的油味等。阐述几种脱除臭味气体技术，对芝麻油机榨车间的臭味气体采用3级静电场+氧聚解，压榨和精炼车间采用微波等离子光氧催化恶臭气体净化，对预处理、浸出和精炼车间产生的臭味气体采用脱臭液喷淋洗涤+复合光催化+VP布气脱臭。3级静电场+氧聚解的臭味气体脱除率达83％，脱臭液喷淋洗涤+复合光催化+VP布气技术的臭味气体排放指标达到国家相关标准。 |
| 英文摘要: |
| Foul smell gas from oils and fats processing plants included small molecules and bean smelly gases produced by oxidation of oils and fats, various kinds of odor and smell oils, meals and n-hexance in the leaching workshop, the foul smell gas from the oxidation of edible oils contacted with chemicals in the oil refinery and sewage disposal, and oily flavor from the fragrant oil press workshop produced by small variety of oil seeds, etc. The several foul smell gas removal technologies were described, such as the three stage electrostaic field and oxidative polymerization used for the sesame oil press workshops,microwave plasma photo-oxygen catalyzed stink gas purification for press and refining workshops and the deodorant spraying washing and composite photocatalysis and neutralization deodorization adopted for pretreatment,leaching and refining workshops.And the removal efficiency of foul smell gas achieved 83% of three stage electrostaic field and oxidative polymerization and the emission index of foul smell gas met national standard by deodorant spraying washing and composite photocatalysis and neutralization deodorization. |
