Description

生物质液化气及其制作方法
技术领域
本发明涉及一种生物质液化气及其制作方法，属于能源与环保。
技术背景
利用活性污泥(简称污泥)作生物质原料产生沼气甲烷气，甲烷气在低温条件下转化成液化气。污泥是指由城乡环境中生活污水处理净化厂、啤酒厂、轻工业污水排放企业等，这些企业排放的污水经过净化处理产生的污泥。据报道资料，我国污水处理净化企业不仅大中城市，而且县域乡镇都建设污水处理净化厂，处理处置利用污泥已经成为城乡卫生环境的需要。活性污泥中含有致病微生物和寄生虫卵，必须采取有效方法安全处理，防止病原体和寄生虫卵传播。
生物质作能源原料是用上述污泥经过厌氧微生物发酵技术处理来实现的。污泥中有机物质在无氧环境中被厌氧菌群消化最终分解生成沼气甲烷气和二氧化碳等的过程，这是目前处理污泥的生化技术。污泥厌氧消化是一个极复杂过程，大体上分为三个阶段：水解阶段、产酸阶段及产甲烷气阶段。在整个发酵过程中，三个阶段相互衔接，连续交替进行。三个阶段之间相互约束又相互依存，维持相对动态平衡。
发明内容
利用活性污泥和适量添加增效剂，以提高产气量用于生物质原料。原料配制后在无氧环境中厌氧微生物菌群进行消化有机物质产生沼气甲烷气。消化池、箱、罐中厌氧菌群需要营养物质，用C/N配比表示，C/N是重要的影响因素。C/N过高，含氧量不足，消化液缓冲能力降低，引起PH值下降；反之，C/N过低，含氧量过高，PH值上升。
试验研究表明，消化容器(池、箱、罐)中PH值对产生甲烷气的最佳值是7.0-7.5，可用石灰调节取得最佳效果。
试验用250kg活性污泥，在封闭容器中进行。5月15日投料，监测计量仪出现可然甲烷气后关闭。于7月1日检测计量仪显示可然甲烷气7立方米。
生物质液化气制作方法
测定产气原料活性污泥中有机物质百分含量，增效剂百分含量。原料均匀混合投入封闭的容器池、箱、罐中进行厌氧发酵。厌氧发酵期视环境气温而不同，通常需要15天至20天。在低温条件下可用申请人的发明专利申请号201410053497.3沼气罐进行发酵。
上述发酵过的原料产生沼气，沼气进入管道，输气管道安装一氧化碳、二氧化碳、二氧化硫、硫化氢、水气、氮气等去除仪自动去除。甲烷气进入管道输送至甲烷气池、箱、罐容器，配制超低温液化气设备使甲烷气液化，获得液化气产品。
