Embodiment 1

[0035] like figure 1 as shown, figure 1 It shows the waste incineration fly ash recycling system provided by the embodiment of the present invention. The system includes a solidification system and a salt separation system. The waste incineration fly ash is processed continuously through the solidification system and the salt separation system, and finally forms an easy-to-recycle substances and non-polluting emissions.

[0036] like figure 2 As shown, the solidification system includes a beating leaching tank, the beating leaching tank is connected to the first solid-liquid separator, the solid phase outlet and the liquid phase outlet of the first solid-liquid separator are respectively connected to the recovery system and the transfer system, and the transfer system is connected to the salt separation system. system.

[0037] Among them, the drying equipment is mainly to dry and screen the solid residue, and transport it to the clinker calcination system of the cement ki...

Embodiment 2

[0052] like Figure 6 as shown, Figure 6 Shown is the domestic waste incineration fly ash recovery and treatment method provided by the embodiment of the present invention, including the following steps:

[0053] S1. Raw liquid separation: import waste incineration fly ash into the beating and leaching tank through a screw feeder, inject water into the beating and leaching tank, stir to form a raw liquid, and the raw liquid is introduced into the first solid-liquid separator through the pump body; the first solid-liquid The separated solids in the separator are introduced into the gradient beating equipment of the recovery system, and the separated mother liquor is introduced into the transfer tank of the transfer system, and the transfer tank is connected to the heavy metal removal equipment;

[0054] S2. Post-treatment of the solid after the separation of the raw liquid: the gradient beating tank dilutes the solid again, and then imports it into the circulating gradient se...

Abstract

The invention discloses a recovery processing system and method for household garbage incineration fly ash. The system comprises a solidification system and a salt separation system, and the waste incineration fly ash is continuously processed through the solidification system and the salt separation system so as to finally form substances which are easy to recycle and emission substances which are pollution-free. The system has the advantages that the system cross processing can be realized, and the maximization of waste recovery can be achieved. In addition, the invention further discloses the recovery processing method for the household garbage incineration fly ash. The method comprises the following steps of S1, carrying out separation on a stock solution; S2, carrying out post-treatment on separated solids of the stock solution; S3, carrying out post-treatment on separated mother liquor of the stock solution; and S4, carrying out salt separation on the separated mother liquor of the stock solution. The method has the advantages that the uniqueness of emission can be guaranteed, namely, the unique emission can reach the emission standard, and the phenomenon that a new pollutantis generated due to the mutual reaction between various standard emission substances can be avoided.

Description

technical field [0001] The invention relates to the recycling and processing non-polluting discharge technology of household garbage incineration in the field of environmental protection, and in particular to a recovery and treatment system and treatment method for household garbage incineration fly ash. Background technique [0002] Environmental pollution is the most important problem faced in modern production and life. Nowadays, the garbage disposal in daily life is roughly divided into landfill and incineration. Most of the waste is incinerated, and waste incineration produces a large amount of fly ash solid particles, and the treatment of solid particles is also particularly critical. [0003] Waste incineration fly ash contains a variety of chemical substances. If the fly ash is discharged directly, the chemical substances in the fly ash will easily cause secondary pollution to the environment, such as heavy metal pollution, chloride ion pollution, etc. Research has f...
