Embodiment 1

[0017] A waste incineration slag treatment process, comprising the following steps:

[0018] (1) Carry out magnetic separation after collecting the slag to remove metal impurities in the slag;

[0019] (2) Send the slag to the vibrating mesh screen for screening, collect the particles with a particle size greater than 5mm, and the particles with a particle size less than 5mm contain some nitrogen and potassium elements, which can be used as agricultural fertilizers;

[0020] (3) Mix the particles with a particle size greater than 5mm, the clay and the binder in the following weight percentages, 40% of the particles with a particle size greater than 5mm, 35% of the clay, and 30% of the binder;

[0021] (4) Add 10% glycerol and phenolic resin solution of mixture weight to the mixture of step (3), then send into the mixer and stir evenly;

[0022] (5) Send the stirred material into the high-pressure chamber for high-pressure compression, and the pressure in the high-pressure cha...

Abstract

The invention discloses a waste incinerator slag processing technology. The technology comprises the following steps: removing metal impurities from slag; sending the obtained slag to a vibration mesh screen, screening, and allowing particles containing nitrogen and potassium elements and having a granularity being smaller than 5mm to be used as an agricultural fertilizer; mixing 40-50wt% of particles with the granularity being greater than 5mm and 25-35wt% of clay with 25-30wt% of an adhesive; adding a glycerin and phenolic resin solution accounting for 10% of the weight of the above obtained mixture, sending the obtained material to a stirrer, and stirring until uniformity; sending the stirred material to a high-pressure chamber, and carrying out high-pressure pressing; and carrying out molding block formation on the compressed material, disposing obtained blocks in a brick kiln, and carrying out high temperature sintering to obtain finished bricks. Waste incinerator slag screening allows fly ash containing N and K elements to be used as the agricultural fertilizer, and the bricks formed after mixing the particles with the granularity being greater than 5mm, clay and the adhesive, pressing and sintering can be used as a building material.

Description

technical field [0001] The invention relates to the technical field of garbage slag treatment, in particular to a garbage incineration slag treatment process. Background technique [0002] Using domestic waste incineration power generation technology, domestic waste will produce slag after incineration at high temperature. The volume of the slag is about 20% to 30% of the original domestic waste. The composition of domestic waste incineration slag is complex, the main components are Ca, Si, Na, N, K, Fe, Al and some heavy metals. my country's waste incineration technology has just started, and there is no suitable treatment method for the slag of waste incineration. Contents of the invention [0003] The object of the present invention is to provide a process for treating waste incineration slag, by screening the waste incineration slag, using fly ash containing N and K elements as agricultural fertilizer, and mixing particles with a particle size greater than 5mm with c...
