US 2023/0129933 A1 · INCINERATOR FLY-ASH PELLETIZATION METHOD AND APPARATUS THEREOF

Abstract

Disclosed is an incinerator fly-ash pelletization method that concentratively arranges incinerated garbage fly ash inside a supporting member, and uses upper and lower molding members that are respectively provided with upper and lower pressing forces of different magnitudes to press and mold the incinerated garbage fly ash into a fly-ash pellet having a rounded projection portion on each of upper and lower surfaces thereof for reuse in a subsequent stage. The rounded projection portion functions to separate multiple fly-ash pellets that are stacked together to facilitate complete combustion, so as to effectively reduce environmental pollution and realize the purposes of recycling and reusing waste resources and improving economic values. The apparatus includes an apparatus chassis, and upper and lower hydraulic cylinders are arranged in the apparatus chassis to respectively connect to the upper and lower molding members that are each provided, at a central portion, with an arc-form shallow trough.

Dependent claims

An incinerator fly-ash pelletization method, comprising:

arranging an upper molding member and a lower molding member in an upper part and a lower part of an apparatus chassis, respectively;
subjecting incinerated garbage fly ash collected from an incinerator to operations of sieving and drying;
disposing an amount of the incinerated garbage fly ash from the incinerator concentratively between the upper molding member and the lower molding member arranged in the apparatus chassis;
adjusting pressing forces supplied from the upper molding member and the lower molding member;
and
pressing and molding the incinerated garbage fly ash into a fly-ash pellet by means of different magnitudes of the pressing forces, which are respectively around 300 tons supplied from the upper molding member and around 10 tons supplied from the lower molding member.

3 more elements

An incinerator fly-ash pelletization apparatus, comprising an apparatus chassis, wherein an upper molding member is arranged in an upper part of the apparatus chassis and is connected to a driving rod of an upper hydraulic cylinder;

a supporting member is arranged in a lower part of the apparatus chassis and a lower molding member is disposed inside the supporting member and connected to a driving rod of a lower hydraulic cylinder;
a feeding structure is arranged at one side of the apparatus chassis, wherein the upper molding member and the lower molding member are each formed, in a central portion thereof, with an arc-form shallow trough;
incinerated garbage fly ash from an incinerator is fed by the feeding structure into the supporting member, and the upper hydraulic cylinder and the lower hydraulic cylinder are operable to apply different pressing forces to respectively drive the upper molding member and the lower molding member, so as to press the incinerated garbage fly-ash into a fly-ash pellet having a rounded projection portion formed at a central part thereof.
