Embodiment 1

[0046] see figure 1 , a method for solidifying waste combustion fly ash, comprising the following steps:

[0047] S1. Put the waste burning fly ash into the solidification box 1, and then add water to the solidification box 1. The amount of water is 1.5 times the amount of fly ash to obtain a solid-liquid mixture;

[0048] S2. Add a plurality of first auxiliary stirring balls 3 into the curing box 1 again, and stir the fly ash and water through the curing box 1 until an adhesive slurry is formed in the curing box 1;

[0049] S3. Let the adhesive slurry in S2 stand for 30 minutes, and heat the curing box 1 to 40° C. for 10 minutes. Pressurize the adhesive slurry in the curing box 1 to form a stable cured product.

[0050] see Figure 2-4 , the upper cover plate of the curing box 1 in S1 is connected to the stirring shaft 2 through bearing rotation, the first auxiliary stirring ball 3 is located in the curing box 1, the bottom of the stirring shaft 2 is fixedly connected to th...

Abstract

The invention discloses a solidification method of waste burning fly ash, which belongs to the technical field of waste burning, and a method for solidifying waste burning fly ash. This solution can promote the inversion of potassium permanganate powder in an open cylinder by means of the heat generated in the stirring process Gradually decompose, so that the air pressure in the corrugated airbag gradually increases, thereby pulling the corrugated airbag to deform downward, on the one hand, it promotes the generated oxygen to push away the rubber seal and release it from the release guide hole, so that the oxygen enters the curing box. Improve the stirring efficiency of the solid-liquid mixture. On the other hand, with the continuous output of oxygen, it can be promoted to react with the first auxiliary stirring ball. The heat released can accelerate the decomposition efficiency of potassium permanganate and improve the efficiency of the whole process. At the same time With the help of the ferric oxide powder produced by the reaction and the blowing effect of oxygen, the ferric oxide powder is evenly blown to the surface of the compressed film.

Description

technical field [0001] The invention relates to the technical field of waste combustion, and more specifically relates to a method for solidifying waste combustion fly ash. Background technique [0002] Waste incineration refers to the process of reducing the volume of waste through oxidation at high temperature through appropriate thermal decomposition, combustion, melting and other reactions, and becomes residue or molten solid matter. Waste incineration facilities must be equipped with flue gas treatment facilities to prevent heavy metals, organic matter, etc. Such pollutants are discharged into the environmental medium again. Recycling the heat generated by garbage incineration can achieve the purpose of recycling waste. Garbage incineration is an older and traditional method of disposing of garbage. After the garbage is treated by incineration, the reduction effect is remarkable, the land is saved, and it can also be eliminated. Various pathogens convert toxic and harm...
