Embodiment

[0092] Before the fly ash is melted at high temperature, it is firstly treated with water to remove chlorine, so that the water content in the washed fly ash is ≤ 30%, and the Cl - Content ≤10mg / g.

[0093] Specifically, the washing process includes:

[0094] Sa: Analyze the chlorine content in the fly ash through multi-point and multi-frequency sampling analysis, that is, establish a multi-tank simultaneous ash discharge operation mechanism, and analyze the chlorine content of the fly ash to be processed every 4 hours;

[0095] Sb: According to the analysis results in Sa, determine the flow rate of washing water according to the water-cement ratio 2-4:1;

[0096] Sc: The fly ash is washed by a multi-stage countercurrent washing process, and the ash water washed in the second stage is separated from the solid by dehydration and pressure filtration. Fresh water is supplemented in the stage washing, and the first plate and frame filter, the second plate and frame filter and th...

Abstract

The invention relates to the technical field of solid waste resource utilization, and discloses a fly ash high-temperature melting treatment compatibility method, a control system, equipment and a storage medium. The fly ash high-temperature melting treatment compatibility method comprises the steps that S1, obtaining fly ash and compatibility raw materials, and obtaining material parts in the fly ash and the compatibility raw materials; s2, generating a compatibility scheme based on the fly ash, the material parts in the compatibility raw materials and the standard parts of the target product; and S3, controlling the dosages of the fly ash and the compatibility raw materials based on the compatibility scheme. By analyzing the content of each part in the fly ash and the compatible raw materials and comparing the content with the standard part amount of the target product, accurate compatibility is realized, the melting temperature is 1250-1350 DEG C, the heat preservation time is 30-60 minutes, and the melting standard can be reached, so that the efficiency is improved, and the energy consumption is reduced.

Description

technical field [0001] The present application relates to the technical field of resource utilization of solid waste, in particular to a fly ash high-temperature melting treatment compatibility method, control system, equipment and storage medium. Background technique [0002] Fly ash refers to the tiny ash particles discharged during the combustion process of fuel (such as coal, domestic garbage, hazardous waste, etc.), and its particle size is generally 1-100 μm, also known as fly ash or soot. Accounting for about 20% of the total amount of waste incineration ash, it is the material collected by the flue gas dust collector after waste incineration. [0003] Fly ash cannot be directly landfilled because it contains a large amount of soluble heavy metals and dioxins, and it is a hazardous waste. Dioxins, heavy metals and a large amount of soluble salts in fly ash can easily seep into soil and groundwater, and then enter the food chain, posing a huge threat to the environmen...
