Method for producing roadbed base material from low-calorific-value solid waste
The invention discloses a method for producing a roadbed base material from low-calorific-value solid wastes, belongs to the technical field of solid waste resourceful treatment, and solves the environmental problem caused by random stacking of the low-calorific-value solid wastes. The method comprises the following steps: naturally airing a certain amount of low-calorific-value solid waste, then air-drying the solid waste, and then crushing and screening the solid waste; adding the material obtained after treatment in the step A into a roasting device to be roasted, and obtaining a roasted material after roasting; cooling the roasted material obtained in the step B to obtain a material of which the temperature is less than 60 DEG C; and adding the material cooled in the step C into a grinding device, and grinding to obtain the roadbed base material. According to the invention, the low-calorific-value solid wastes are subjected to aerobic roasting, so that organic matters in the low-calorific-value solid wastes are volatilized, and residues are mainly silicon dioxide and other components, so that the low-calorific-value solid wastes can be turned into wealth as a roadbed base material, and the purpose of efficient and comprehensive utilization is achieved.
本发明公开了一种低热值固体废弃物生产路基基础材料的方法，属于固废资源化处理技术领域，解决了低热值的固体废弃物随意堆放带来的环境问题。本发明包括以下步骤：将一定量的低热值固体废弃物经自然晾晒后风干，然后破碎筛分；将步骤A处理后得到的物料加至焙烧装置中焙烧，焙烧后得到焙烧料；对步骤B得到的焙烧料进行冷却，冷却后得到温度＜60℃的物料；将步骤C冷却后的物料加入磨粉装置中进行研磨，研磨后得到路基基础材料。本发明将低热值固体废弃物经有氧焙烧，使其中的有机物挥发，剩余物主要为二氧化硅等成分，以此作为路基基础材料，能够实现低热值固体废弃物变废为宝，达到高效综合利用的目的。
