Problems solved by technology

However, after the waste residue fly ash enters the landfill, it is exposed to the sun, rain, and wind, and the harmful components in it can directly or indirectly cause water resources to be polluted through soil, surface or underground water bodies, etc.
Garbage ash also contains a large amount of fine powder and particles, which enter the atmosphere in strong winds, pollute the air, produce haze weather, cause new secondary environmental pollution, and cause great harm to human health
Long-term landfill also needs to occupy a large amount of land resources. How to scientifically treat and dispose of garbage ash and solid waste to make it harmless and resourceful

Embodiment 1

[0051] Sorting and crushing household garbage, office and commercial activity sites, farmers' markets, garden cultivation and production, sanitation systems cleaning roads, streets, squares, parks and other public places, and waste residues discharged after incineration and power generation 1. After removing scrap metal by magnetic separation, it is crushed, dried, wheel-milled, and sieved to make garbage ash powder with a fineness of less than -0.045mm;

[0052] The waste ash discharged by the flue gas system during the incineration of domestic waste for power generation is sorted and magnetically separated to remove scrap metal, then dried, wheel milled and sieved to make a fly with a fineness of less than -0.04mm. ash powder;

[0053] The river sand excavated from the river channel is naturally dehydrated, dried and sorted to make river sand powder with a particle size of less than -3mm;

[0054] Quicklime is made of limestone with a fineness of 125um lime powder after hig...

Embodiment 2

[0057] Get the garbage ash powder 53kg of embodiment 1, fly ash powder 12kg, river sand 26kg, Portland cement 9kg, lime powder 15kg, calcium sulfate powder 5kg, polycarboxylate water reducer 0.8kg, aluminum Powder 0.08kg, saponin powder 0.4kg, borax 0.04kg, sodium chloride 0.8kg and water 38kg, the above-mentioned raw materials are stirred into a lake shape with a biaxial mixing mixer, poured into the mold, stop gas generation, solidify, and mechanically Cut into shape, then send the formed garbage ash slag aerated concrete recycled blocks into the autoclave for steam curing, first heat up for 2 hours, then keep the temperature at 100 degrees for 7 hours, and then cool down naturally for 1.5 hours to make garbage ash Slag aerated concrete recycled block products. After testing, the average compressive strength is: 5.8Mpa, and the minimum value of a single group is: 4.6Mpa, which is a qualified product.

Embodiment 3

[0059] Get the garbage ash powder 60kg of embodiment 1, fly ash powder 10kg, river sand 30kg, Portland cement 8kg, lime powder 18kg, calcium sulfate powder 4kg, polycarboxylate water reducer 1.0kg, aluminum Powder 0.07kg, saponin powder 0.6kg, borax 0.03kg, sodium chloride 1.0kg and water 35kg, the above raw materials are stirred into a lake shape with a biaxial mixing mixer and then poured into the mold, statically stopped to generate gas, solidified, and mechanically Cut into shape, and then send the formed garbage ash slag aerated concrete recycled blocks into the autoclave for steam curing. First, heat up for 2.5 hours, then keep the temperature at 98 degrees for 6 hours, and then cool down naturally for 2 hours to make garbage ash Slag aerated concrete recycled block products. After testing, the average compressive strength is: 6.0Mpa, and the minimum value of a single group is: 4.8Mpa, which is a qualified product.

Abstract

The invention relates to an aerated concrete regenerative building block produced by using garbage clinkers and a manufacturing method thereof. The manufacturing method comprises the following steps of: adopting the garbage clinkers, flying ash, river sand, silicate cement, lime, calcium sulfate, poly-carboxylate water reducing agent, aluminum powder, glcditsia sinensis powder, borax, sodium chloride and water as raw materials; stirring the raw materials into a paste by using a double-shaft hybrid stirring machine, and pouring the paste into a die; performing delaying curing for gas development and solidification; forming the paste through machinery cutting; putting the formed garbage clinker aerated concrete regenerative building block into a still kettle to perform steam curing; and raising the temperature to heat up the building block for 2 to 3 hours first, heating the building block for 5 to 8 hours at a constant temperature of between 95 and 100 DEG C, and then naturally cooling the building block for 1 to 2 hours to obtain a garbage clinker aerated concrete regenerative building block product. The product has the advantages and effects of light weight, high strength, no pollution, low cost and good benefit, and accords with a national prescription for saving energy, reducing emissions, developing low-carbon economy and protecting the environment.

Description

technical field [0001] The invention relates to a regenerated aerated concrete block produced from garbage ash. Specifically, it is sorted, crushed, pulverized, and then sorted, broken, and crushed from domestic garbage incinerated from furnace bottom waste and chimney dust removal fly ash. The regenerated aerated concrete block produced from the selected powder as the main raw material belongs to the field of waste treatment. [0002] The invention also relates to a manufacturing method of the waste ash slag aerated concrete regeneration block. Background technique [0003] With the rapid development of my country's economy, the scale of urban development continues to expand, the urban population increases and the population is highly concentrated, and with the continuous improvement of people's living standards and consumption concepts, the generation of urban domestic waste is also increasing. Household garbage mainly comes from the daily life and consumption of resident...
