Description
Technical field
The present invention relates to a kind of disposal of resources of solid waste, the preparation process of specifically a kind of acidic group functional material.
Background technique
With the development of the social economy, living standards of the people improve rapidly, house refuse annual output up to 1.8 hundred million tons with
On, and with the increase of annual 8%~10% speed.The processing of house refuse has become China's one of problem urgently to be resolved.Closely
The national main processing disposal options to house refuse have landfill and burning over year, wherein incineration method is innoxious with its, minimizing,
The advantage of recycling has obtained extensive use both domestic and external.But it can be generated in its vent gas treatment link and account for about the total matter of rubbish
The flying dust of amount 5% or so, it is estimated that about 400~5,000,000 tons of flying dust year yield of China at present.Domestic garbage incineration flyash is big
It is mostly collected in the deduster of garbage incinerating tail gas treatment process, the toxic pollutants such as heavy metal in incineration flue gas are easily enriched in
In flying dust, make the heavy metal contained in flying dust and noxious material difficult to degrade.It, can be to neighbouring environment if unprocessed direct landfill
It causes seriously to pollute.
Domestic garbage incineration flyash resource utilization is the unique channel to solve the above problems.Domestic garbage incineration flyash
Resource utilization must pay attention in terms of the utilization of resources and environment influence two.In current research, consumer waste incineration
The resource utilization of flying dust needs to consider 3 each factors: (1) service performance and cost.Good service performance and low cost
It is resource utilization and the necessary condition that the marketization is promoted.(2) flexibility (adaptability) of operation.This is mainly determined by the physicochemical properties of flying dust
It is fixed.(3) meet environmental standard and there are long-time stability.
The main component of domestic garbage incineration flyash belongs to CaO-SiO2-Al2O3-Fe2O3Certain admixture warps are added in system
After medicament excitation, it may occur that the reaction of a series of complex forms the zeolite structured material of class, has preferable adsorptivity, can be with
Certain treatment effect is played to the pollutant including heavy metal, is met environmental requirements.Therefore it can be burnt with house refuse
It burns flying dust and prepares economic and environment-friendly acidic group functional material.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, propose a kind of preparation process of acidic group functional material, this
Invention produces new function material using domestic garbage incineration flyash and calcining shale, realizes " turning waste into wealth ".With great
Environment, economic and social benefit.
The technical solution of the present invention is as follows: a kind of preparation process of acidic group functional material, the specific steps of which are as follows:
(1), appropriate shale is taken, natural cooling after calcining is ground up, sieved spare；
(2) 40~60 parts of incineration of refuse flyash, 40~60 parts of admixture (butt), 20~25 parts of exciting agent, are weighed, is mixed
Uniformly；
(3) 15~25 parts of water, are added, is placed in net slurry blender and stirs evenly；
(4), jolt ramming in slurry injection mold；
(5), the mold for finishing slip casting covers with one layer of heat preservation film, is placed in 30~55 DEG C of constant temperature weather curing box and conserves 2
Demoulding after~5 hours；
(6), the block after demoulding is placed in dry curing box, obtains acidic group function after 12~21d of dry curing at 60~80 DEG C
It can material.
Calcination temperature described in preferred steps (1) is 600~800 DEG C；Calcination time is 2~5h.
Preferred steps are ground up, sieved described in (1) to sieve with 100 mesh sieve.
Exciting agent described in preferred steps (2) is one of phosphoric acid, acetic acid or sulfuric acid or a variety of.
Speed of agitator described in preferred steps (3) is 100~200 revs/min, and mixing time is 10~20min.
Jolt ramming frequency described in preferred steps (4) is 20~30 beats/min, and the jolt ramming time is 3~5min.
The utility model has the advantages that
1, nourishment's time is short, can reduce the production cycle, there is certain economy；
2, flying dust utilization rate is high, and the useless rate of technique benefit is big, can high degree realization refuse reclamation；
3, product can effectively close the heavy metal in flying dust, while have preferable water storage, water permeability, have certain ring
Border benefit.
