Abstract

The invention provides a waste incineration fly ash high-temperature melting balling device. The waste incineration fly ash high-temperature melting balling device comprises a trapezoidal support, a first base, a first turnover mechanism, a granulation disc, a rotating driving device, a second base, a second turnover mechanism, a linear driving device and a sieve plate; the second base is rotationally connected with the waist part of the trapezoidal support, the first base is also obliquely arranged, and the second turnover mechanism is connected between the lower end of the second base and the bottom surface of the trapezoidal support; the sieve plate is arranged below the disc wall of the granulation disc, and the sieve plate is matched with the disc wall of the granulation disc in outline; the linear driving device is arranged on the top surface of the lower end of the second base, and the output end of the linear driving device is connected with the sieve plate so as to push the sieve plate to extend to the outer side of the disc wall of the granulation disc. The second base and a screen are additionally arranged on an existing disc granulator, so that fly ash balls with uniform particle sizes are screened out during granulation centrifugal unloading in the granulation disc, the functions of the existing disc granulator are improved, screening equipment does not need to be purchased, and the cost is reduced.

Description

technical field

[0001] The invention relates to the technical field of garbage incineration fly ash melting, in particular to a high-temperature melting pelletizing device and a pelletizing method for garbage incineration fly ash. Background technique

[0002] At present, incineration is the main disposal method of domestic waste in my country. It has the advantages of large processing capacity, obvious reduction, complete harmlessness, and heat energy can be used as a resource. Due to the complex composition of domestic waste in our country, the fly ash produced after incineration of domestic waste contains a large amount of heavy metal elements (such as Pb, As, Cr and Cd, etc.) and highly toxic organic carcinogens (dioxins), which seriously endanger the health and safety of residents. environment safety.

[0003] The harmless treatment technologies of waste incineration fly ash include melting / vitrification solidification, cement solidification, chemical stabilization, ac...
