Method for producing cat litter from coal-series solid waste

Abstract

The invention discloses a method for producing cat litter from coal-series solid waste. The method comprises the following steps: S1, filling fluidized bed fly ash into a powder bin for later use; warehousing bentonite for later use; crushing and grinding the carbide slag to obtain powder with the particle size of less than 200 meshes, and filling the powder into a powder bin for later use; s2, the fluidized bed fly ash, the bentonite and the carbide slag powder in the S1 are put into a mixing machine according to the proportion to be stirred, and then water is added for mixing to prepare granular cat litter; and S3, stacking the granular cat litter in the S2, naturally curing, drying, bagging and warehousing. According to the method for producing the cat litter, fluidized bed fly ash, bentonite and carbide slag are adopted as raw materials, the cat litter is compact in structure and free of harmful chemical components, and the fluidized bed fly ash contains fine dust pores, so that harmful elements and bacteria in the environment can be adsorbed, harmful substances can be subjected to active biodegradation, and the use requirements of the cat litter can be met; the adopted raw materials are all solid wastes, the manufacturing cost is low, and the problem that the fluidized bed fly ash occupies land is effectively solved.

Description

technical field [0001] The invention relates to the technical field of resource utilization of solid waste, in particular to a method for producing cat litter from coal-based solid waste. Background technique [0002] Fluidized bed coal combustion technology is an efficient, pollution-free and clean coal combustion technology, and fluidized bed ash is industrial solid waste discharged from fluidized bed boilers. Because of its unique high sulfur content and high calcium content, it has not been effectively used on a large scale. At present, most of them are stacked in the open air in China, occupying land resources, and even affecting the further promotion of fluidized bed coal combustion technology. [0003] Cat litter is a bedding material for small animals such as pet cats and dogs in the family. It has the advantages of deodorization, strong adsorption, non-toxic, non-polluting, and less garbage. It is a green and environmentally friendly product for household use. Cat ...
