AI Technical Summary

Technical Problem

The existing technology for treating fly ash incineration is mainly cement curing method. Although it can achieve harmless treatment, it cannot be recycled and utilized, which wastes resources and fails to achieve rational resource utilization.

Method used

A construction aggregate granulation device based on waste incineration fly ash particles is used to form CaCO3 by mixing fly ash, water and Na2CO3, and then granulating it with silicate cement, sulfur aluminate cement and other materials to form a construction aggregate blast body. The device includes a reactor, a mixing and stirring device, a granulating device and a primary forming device, and the full mixing and granulating of materials are achieved through the control of the valve assembly.

Benefits of technology

The resource conversion of fly ash is realized, and aggregate can be used for building materials is formed, which solves the problem of resource waste in fly ash treatment. The yield of aggregate is improved by heating the preforming device, preventing adhesions and improving the quality of aggregates.

Abstract

The present invention discloses a building aggregate and granulation device based on fly ash particles from garbage incineration, belonging to the technical field of building materials, including a reactor, a mixing and stirring device, a granulation device and a primary forming device, wherein the mixing and stirring device is arranged between the reactor and the granulation device, and the primary forming device is arranged at the output end of the granulation device. The present invention arranges a reactor, a mixing and stirring device, a granulation device and a primary forming device, firstly puts fly ash, water and a set amount of Na2CO3 into the reactor for reaction to produce CaCO₃, so that the mixed material in the reactor enters downward into the mixing and stirring device, and at the same time, granulation materials are added into the mixing and stirring device, and then the mixed material is fully stirred in the mixing and stirring device to form a slurry, so that the slurry enters the granulation device for granulation, and the particles produced by the granulation device first enter the primary forming device, and the primary forming device preheats the particles for preliminary forming, so as to achieve the purpose of producing fly ash into granular aggregate.
