CN103060044A 一种污泥与生物质混合制备固体燃料的方法 无效 - 驳回 转让

一种污泥与生物质混合制备固体燃料的方法
摘要：
本发明公开了一种污泥与生物质混合制备固体燃料的方法，包括以下步骤：（1）预处理：向污泥中加入占污泥干基质量1%～5%的添加剂，将所得混合物脱水干燥至含水率为10%～25%，粉碎过筛，形成污泥干化原料；将生物质脱水干燥至含水率为10%～25%，粉碎过筛，形成生物质干化原料；（2）混合与成型：将污泥干化原料与生物质干化原料混合并搅拌，得到原料混合物，其中污泥干化原料的质量分数为30%～70%，生物质干化原料的质量分数为70%～30%；将原料混合物挤压成型，得到固体燃料。本发明的方法成本低廉、节能环保、实现了固体废物与生物质的资源化利用，可有效解决固体废物与生物质的处理处置问题。
摘要（英）：

The invention discloses a method for preparing a solid fuel by mixing sludge and biomass. The method comprises the following steps: (1) pretreating: adding additive accounting for 1-5% of the dry basis quantity of the sludge to the sludge; dewatering and drying the obtained mixture until the water content is 10-25%; crushing and sieving to form dried sludge raw material; dewatering and drying the biomass until the water content is 10-25%; crushing and sieving the biomass so as to obtain dried biomass raw material; (2) mixing and forming: mixing and stirring the dried sludge raw material and the dried biomass raw material to obtain a raw material mixture, wherein the mass fraction of the dried sludge raw material is 30-70%; the mass fraction of the dried biomass raw material is 70-30%; and extruding and forming the raw material mixture so as to obtain the solid fuel. The method disclosed by the invention is low in cost, energy-saving and environment-friendly, realizes the recycle of the solid waste and the biomass and effectively solves the treatment problem of the solid waste and the biomass.
