Description
Technical field
The present invention relates to solid waste recycling and reusing fields, and in particular to utilizes domestic garbage burning electricity generation waste residue system
The method and product of standby premixing mortar.
Background technique
With the fast development of China's Development of China's Urbanization, the yield of domestic waste is constantly promoted.By 2017
Bottom, the storage of China's domestic waste are still increased every year with 5%~8% speed more than 8,000,000,000 tons, how innoxious place
House refuse is managed, solves the problems, such as that rubbish surrounds city, garbage environment pollution has become current urgent problem to be solved.
The common method of China's processing domestic waste has sanitary landfills, burning disposal, compost, anaerobic digestion etc.,
The processing of middle consumer waste incineration has minimizing, innoxious, recycling compared to other processing modes, without long-term responsibility and just
The prompt advantage for efficiently waiting five aspects.The especially emergence of mechanical kiln grate furnace and fluidization in recent years is waste incineration skill
The development of art creates advantage, promotes the development of incineration treatment of garbage technology.The product generated after waste incineration is called
Lime-ash.Lime-ash collects source by it, is generally divided into 3 classes: bottom ash, cigarette ash purification system flying dust and mixing bottom ash.Bottom ash, which refers to, burns
The residue being discharged after burning from siege tail end, quality accounts for about 80% or so of lime-ash gross weight, therefore it is the main component of lime-ash,
So lime-ash is generally defaulted as bottom ash.The bottom ash quality that domestic garbage burning electricity generation generates only has the 20% of original rubbish quality
~30%, volume only accounts for 10% or so of original volumes, tentatively realizes the purpose of minimizing.But how house refuse to be burnt
Burning bottom ash (hereinafter referred to as " bottom ash ") further resource utilization is the topic that people widely pay close attention to.
We need to take scientific and reasonable measure to be allowed to turn waste into wealth to handle and utilize these rubbish, for our institutes
It utilizes.The waste residue that the power generation of digestion process house refuse generates how is carried out, the efficient utilization of this part waste residue is realized, researchs and develops
High added value tailings product fully achieves the target of waste-to-energy plant waste residue " zero " discharge, it has also become house refuse power generation
The necessity that enterprise improves benefit with social harmonious development.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of premixing mortar systems for blending domestic garbage burning electricity generation waste residue
Preparation Method, crushing grinding house refuse power generation bottom ash are allocated as replacing the recycled aggregate sand of yellow ground and replace flyash, part of cement
Regenerative micro powder, premixing mortar is made, resistance to compression, flexural strength can be guaranteed, and it is useless to not only solve house refuse power generation
The processing problem of slag, while also saving the production cost of premixing mortar.
The invention is realized by the following technical scheme:
A kind of premixing mortar preparation method blending domestic garbage burning electricity generation waste residue, comprising the following steps:
1) by house refuse power generation waste residue drying 12h to constant weight, it is crushed waste residue partial size≤5mm, 1~5mm's of separation screening partial size
Waste residue is that recycled aggregate is husky, and the polymerization of the activity excitant of its quality 2~3 ‰, 0.5~1 ‰ is added in the waste residue of partial size < 1mm
Polyol grinding aids are ground, and obtain fineness up to the regenerative micro powder of 6000~7000 mesh, exciting agent includes mass ratio 1:2~3
Triacetic acid ammonium and sodium chloride mix；
2) regenerative micro powder, cement, recycled aggregate sand, water-reducing agent and tackifier are weighed by following mass ratio:
0.15~0.25 part of regenerative micro powder
0.75~0.85 part of cement
2~3 parts of recycled aggregate sand
1~2 part of water-reducing agent
0.5~1 part of tackifier
Excess water；
3) regenerative micro powder of above-mentioned weighing, cement, recycled aggregate sand are poured into blender, is stirred evenly, then pour into weighing
Water-reducing agent, regulator and the common mix of water are uniform, obtain premixing mortar.
House refuse power generation waste residue crushing grinding, a part are allocated as recycled aggregate sand and replace yellow ground, and another part is added special
The activity excitant and grinding aid of system, which are further ground, is made regenerative micro powder, replaces flyash and part of cement, is applied to premixing
Mortar, thus realize house refuse power generation waste residue all of.
Can exploitation house refuse power generation waste residue be applied in premixing mortar, realize sufficiently grinding for house refuse power generation waste residue
Mill, reaches the activity of corresponding fine grinding degree and admixture product, this answers the later period of house refuse power generation waste residue admixture
With conclusive influence will be generated, develops specific grinding aid and activity excitant is critical problem.If not adding this grinding aid
Agent need to extend milling time 40% and just reach required fineness, and not add the waste residue gelation activity only up to 50% or so of activity excitant,
Be added this activity excitant activity can >=70%.
The present invention is further improved scheme, the water-reducing agent be lignin sulfonate or Ppolynuclear aromatic salt or
Water-soluble resin Sulfonates.
The further improvement project of the present invention is that the drying of step (1) house refuse power generation waste residue removes iron power removing after being crushed.
The present invention also provides prepare resulting blending house refuse power generation according to method either described in claims 1 to 3
The premixing mortar of waste residue.
Compared with prior art, the present invention having following obvious advantage:
The present invention smash and grind etc. processing to house refuse power generation waste residue, classification obtain the recycled aggregate sand of substitution yellow ground with
Replace the regenerative micro powder of flyash, part of cement, the premixing mortar requisite quality of production.It is useless thoroughly to solve house refuse power generation
Slag all of, fully achieve " zero " discharge target, develop high added value tailings product；Concrete is also reduced simultaneously
The production cost of enterprise's premixing mortar.
