Lightweight ceramsite fired from solid waste and method thereof
The invention provides a lightweight ceramsite fired from solid wastes and a method thereof. The invention relates to a method for firing light ceramsite by using solid wastes. The method comprises the following steps: S1, preparing materials: selecting an undisturbed raw material of gold tailings, an undisturbed raw material of waste incineration fly ash and polluted soil for later use; s2, preparing a core: adding water into the raw materials in the S1, and mixing to prepare a mixture containing the core; s3, balling and screening: adjusting and preparing water quantity for balling, and selecting wet raw material balling; s4, drying and dehydrating: drying and dehydrating the wet raw material nodules to obtain dry raw material nodules; and S5, firing: transferring the dry raw material pellets into a roasting furnace, preheating, roasting and cooling to obtain the lightweight ceramsite. According to the light ceramsite fired by utilizing the solid waste and the method thereof, the gold tailings are used as the main raw material, the waste incineration fly ash is matched as the fluxing agent and the binder, then the polluted soil is added as the plastic material, and the light ceramsite fired by utilizing the solid waste has excellent performance through the processes of granulation, drying, preheating, roasting and the like; the method for firing the light ceramsite by using the solid wastes has the advantages of high preparation efficiency, low energy consumption and low cost, realizes full resource utilization of the gold tailings, the waste incineration fly ash and the polluted soil, and has good economic benefits, environmental protection benefits and social benefits.
本发明提供了一种利用固体废弃物烧制的轻质陶粒及其方法。利用固体废弃物烧制轻质陶粒的方法，包括以下步骤：S1、备料：选取黄金尾矿原状原料、垃圾焚烧飞灰原状原料以及污染土备用；S2、配制成核：将S1中的原料加水混合，制备含球核的混合料；S3、成球筛分：调整、配制水量进行成球，选取湿生料球；S4、干燥脱水：对湿生料球进行干燥脱水，获取干生料球；S5、烧制：将干生料球转移至焙烧炉中，经预热、焙烧、冷却，制得轻质陶粒。本发明的一种利用固体废弃物烧制的轻质陶粒及其方法，以黄金尾矿为主要原料，配以垃圾焚烧飞灰作为助熔剂和粘结剂，再加入污染土作为塑性料，经造粒、干燥、预热、焙烧等过程，使得利用固体废弃物烧制的轻质陶粒具有优异的性能，利用固体废弃物烧制轻质陶粒的方法具有制备效率高、能耗低、成本低的优点，实现了黄金尾矿、垃圾焚烧飞灰和污染土的全资源化利用，具有很好的经济效益、环保效益和社会效益。
