Deodorizing ceramsite and preparation method thereof
The invention discloses deodorization ceramsite and a preparation method thereof, and belongs to the technical field of waste gas treatment. The ceramsite comprises the following components: 10-20% of dry sludge, 20-30% of fly ash, 30-50% of bentonite, 10-20% of clay, 5-10% of a pore-forming agent and 5-10% of an alkaline substance. The preparation method comprises the following steps: firstly, uniformly mixing all the raw materials except the pore-forming agent, granulating, then uniformly mixing the raw material nodules subjected to primary granulation with the pore-forming agent and other raw materials again, granulating, and finally drying, preheating, roasting and cooling. The prepared ceramsite is rich in outer pores, growth of microorganisms is guaranteed, filler blockage caused by excessive breeding of the microorganisms can be avoided, meanwhile, the strength and corrosion resistance of the ceramsite can meet the use requirements of a deodorization filter tank, the ceramsite has an acidity buffering function, the odor removal effect is effectively guaranteed, the preparation process is simple, and the ceramsite is suitable for industrial production. The energy consumption is low, and the purpose of recycling resources is achieved.
本发明公开了一种除臭陶粒及其制备方法，属于废气处理技术领域。本发明的陶粒组分包括：干污泥10～20％，粉煤灰20％～30％，膨润土30％～50％，粘土10～20％，造孔剂5～10％，碱性物质5～10％；其制备方法为：首先，将除造孔剂以外的所有原料进行混匀并造粒，然后再将一次造粒后的生料球与造孔剂及其他原料再次混匀后造粒，最后干燥、预热、焙烧及冷却。本发明制成的陶粒外孔隙丰富，即保证了微生物的生长又能避免微生物过度繁殖造成填料堵塞的情况，同时该陶粒的强度和耐腐蚀度均可达到除臭滤池使用的要求，并具有酸度缓冲功能，有效保证了臭气的去除效果，制备工艺简单，能源消耗低，并且达到了资源循环利用的目的。
