摘要
文章介绍了将资源性废弃物餐厨垃圾经两相厌氧发酵、膜纯化处理后转化为新能源—天然气级燃气系统;以及该系统中的主要装置发酵罐和膜分离组件的结构设计、相关零部件的选择。本系统采用自行设计的中空纤维聚酰亚胺膜组件作为主纯化脱碳装置,在反应温度为25℃条件下,对0.6 MPa的沼气原气进行初步一级膜纯化试验,纯化前后沼气的组分含量CH4从56.72%升至81.90%,CO2从37.80%降至13.69%。该一级膜纯化试验为大中型沼气工程膜分离纯化系统的开发提供了理论基础和实践依据。
This article describes the biogas production from food waste by two-phase anaerobic fermentation process and the purification by membrane process. The whole system convert the biomass into the new energy, and then the natural gas-lev- eled fuel gas. And the structure design of the main device, fermentation tank and membrane separation component, the choice of the related parts, were also presented. The system used a self-designed hollow fiber polyimide membrane module for decarburization as the main purification process. The initial membrane purification was tested at temperature of 25 ℃and original biogas gas of 0.6 MPa. After the purification, the CH4 content of biogas rose from 56.72% to 81.90%, and CO2 drop from 37.80% to 13.69%.
