Embodiment 1

[0056] A preparation process for non-sintered garbage tailings bricks, comprising the following steps:

[0057] 1) Dry the incineration residue to a moisture content of 3-8%;

[0058] 2) Crushing the drying and incineration residue until the particle size is no more than 3mm, which becomes a natural gradation;

[0059] 3) Wheel mill mixing process: 82.9 parts by weight of incineration residue, 4 parts by weight of MSW fly ash, 8 parts by weight of sea shell ash, 4 parts by weight of microsilica, 1.1 parts by weight of F14 activator, 10 parts by weight Input the water into the XLH-800 planetary wheel mill mixer for mixing and grinding, and the grinding time is 6min to form a mixture;

[0060] 4) Mixed material digestion process: input the mixed material into the continuous digestion bin for continuous digestion, the temperature in the bin is kept at 60°C, and the digestion time is 3 hours to become digested material;

[0061] 5) Digestive material mixing and repeated wheel mi...

Embodiment 2

[0065] A preparation process of non-sintered garbage tailings brick:

[0066] 1) Same as embodiment 1 process step 1);

[0067] 2) Same as embodiment 1 process step 2);

[0068] 3) Wheel grinding mixing process: 79.2 parts by weight of incineration residue, 5 parts by weight of MSW fly ash, 10 parts by weight of sea shell ash, 5 parts by weight of microsilica, 0.8 parts by weight of F14 activator, 12 parts by weight Input the water into the XLH-800 planetary wheel mill mixer for mixing and grinding, and the grinding time is 6 minutes to form a mixture;

[0069] 4) The mixture digestion process step is the same as the process step 4) of embodiment 1;

[0070] 5) Digestive material mixed and repeated wheel milling process steps: input 90 parts by weight of digested material, 10 parts by weight of consolidation agent, and 0.06 parts by weight of polycarboxylate superplasticizer into the XLH-800 planetary wheel mill for mixing Machine mixing, repeated round milling, milling tim...

Embodiment 3

[0074] A preparation process of non-sintered garbage tailings brick:

[0075] 1) Same as embodiment 1 process step (1);

[0076] 2) Same as embodiment 1 process step (2);

[0077] 3) Wheel grinding mixing process: 75.5 parts by weight of incineration residue, 6 parts by weight of MSW fly ash, 12 parts by weight of sea shell ash, 6 parts by weight of microsilica, 0.5 parts by weight of F14 activator, 13 parts by weight Input the water into the XLH-800 planetary wheel mill mixer for mixing and grinding, and the grinding time is 6 minutes to form a mixture;

[0078] 4) The mixture digestion process step is the same as the process step 4) of embodiment 1;

[0079] 5) Digestive material mixed and repeated wheel milling process steps: input 87 parts by weight of digested material, 13 parts by weight of consolidation agent, and 0.06 parts by weight of polycarboxylate superplasticizer into the XLH-800 planetary wheel mill for mixing Machine mixing, repeated round milling, milling t...

Abstract

The invention discloses a non-fired rubbish gangue brick, and in particular relates to a non-fired rubbish gangue brick which is made of incineration residues generated from waste incineration and waste incineration of power plants, fume emitted from chimneys after incineration, incineration fly ash collected by using a special capturing device, sea wastes such as seashell lime, an agglomerator and the like by using innovative processes. On premise of resource utilization of wastes, the non-fired rubbish gangue brick has the purposes of low energy and resource consumption and low environment burden, stable and reliable technique methods are utilized to make wall materials with stable quality and good use properties and security properties, and sustainable development of economy, society and environment can be achieved.

Description

technical field [0001] The invention relates to a non-sintered garbage tailings brick, in particular to a non-sintered garbage tailings brick and a preparation process thereof. Background technique [0002] The rapid development of the national economy, the promotion of industrial and agricultural production and the improvement of people's lives and materials have brought about a huge and increasing amount of waste - garbage, which needs to be incinerated and landfilled. Waste incineration is an advanced waste reduction technology at home and abroad. Since the incineration residue and incineration fly ash (referred to as MSW fly ash) produced in the process of waste incineration contain many types and high proportions of heavy metals such as mercury, chromium, lead, nickel, copper, aluminum, tin, vanadium, molybdenum, iron, and manganese, etc. And it contains a large amount of chloride ions, and also contains highly toxic and harmful dioxins, etc., and ordinary treatment me...
