Description

工业沼气发电与清洁秸秆制浆联动法
技术领域 本发明是新能源和生物新材料领域的发明。
背景技术 农用小型沼气已推广使用多年，而工业沼气发电仍处于研发试产阶段，仍存在三大难题：一、有机物发酵产生沼气时间长，产气率低，难以实现工业化发电；二、工业沼气发电时产生的大量蒸汽、热水无处利用白白浪费；三、沼渣沼液作为肥料肥效低难与化肥竞争售价较低。而清洁秸秆制浆也存在三大不足：一、制浆用电量大成本高；二、用蒸汽和热水量大，尤其是部分地区禁止燃煤锅炉后成本更高；三、制浆废液处理工序较多工艺繁杂投入高操作难度大。将工业沼气发电与清洁秸秆制浆相结合则可以有效解决两者难题，变难题为优势，实现相辅相成，优势互补。
发明内容 本发明将清洁秸秆制浆80度温度的废液与畜禽粪便、生活垃圾混合后输送至带有搅拌装置的密封沼气发生罐中，温度保持50-60度，搅拌速度100-200转，每10小时可产沼气80％(与原料比)。将产生的沼气输送到沼气贮存罐中，通过分离器去除杂气后送往沼气发电机组发电，再将所发的电直接输送到变压器供制浆造纸用电，将蒸汽与热水用于制浆造纸。沼渣中富含制浆过程中添加的硅钙、钾和氢化纤维素，制作可缓释氮素、促进磷素分解并快速移动供植物吸收的生物有机钾肥。
具体实施方式 1、将清洁秸秆制浆80度温度的废液与畜禽粪便、生活垃圾混合后输送至带有搅拌装置的密封沼气发生罐中。
2、沼气发生罐温度保持50-60度，搅拌速度每分钟100-200转，每10小时可产沼气80％(与原料比)。
3、将产生的沼气输送到沼气贮存罐中，通过分离器去除杂气后送往沼气发电机组发电。
4、将发电厂发的电输送到变压器供制浆造纸用电、蒸汽和热水直接引入造纸厂，供制浆、造纸使用大量蒸汽和热水。
5、沼渣中富含制浆过程中添加的硅钙、钾和氢化纤维素，制作即可缓释氮素，又能促进磷素分解并快速移动供植物吸收的生物有机钾肥。
