Description
Technical field
The present invention relates to a kind of disposal of resources of solid waste, specifically a kind of preparation technology of acidic group functional material.
Background technology
With the development of the social economy, living standards of the people are improved rapidly, house refuse annual production up to 1.8 hundred million tons with
On, and with annual 8%~10% speed increase.The processing of house refuse has turned into one of China's problem urgently to be resolved hurrily.Closely
Year over the national main processing disposal options to house refuse have landfill and burn, wherein burning method with its innoxious, minimizing,
The advantage of recycling has obtained extensive use both domestic and external.But, it can be produced in its vent gas treatment link and account for the total matter of rubbish
The flying dust of amount 5% or so, it is estimated that about 400~5,000,000 tons of yield of China's flying dust year at present.Domestic garbage incineration flyash is big
Collected more in the deduster of garbage incinerating tail gas processing procedure, the toxic pollutant such as heavy metal in incineration flue gas is easily enriched in
In flying dust, make the heavy metal and difficult degradation noxious material contained in flying dust.If unprocessed directly fill, can be to neighbouring environment
Cause severe contamination.
Domestic garbage incineration flyash recycling is the unique channel solved the above problems.Domestic garbage incineration flyash
Recycling must pay attention in terms of the utilization of resources and ambient influnence two.In current research, consumer waste incineration
The recycling of flying dust needs to consider 3 each factors：(1) performance and cost.Good performance and low cost
It is the necessary condition that recycling and the marketization are promoted.(2) flexibility (adaptability) of operation.This is mainly determined by the physicochemical properties of flying dust
It is fixed.(3) environmental standard is met and with long-time stability.
The main component of domestic garbage incineration flyash belongs to CaO-SiO2-Al2O3-Fe2O3System, adds some admixture warps
After medicament is excited, it may occur that the reaction of a series of complex, the zeolite structured material of class is formed, can be with preferable adsorptivity
Certain treatment effect is played to the pollutant including heavy metal, environmental requirement is met.Therefore it can be burnt with house refuse
Burn flying dust and prepare economic and environment-friendly acidic group functional material.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, a kind of preparation technology of acidic group functional material is proposed, this
Invention is realized " turning waste into wealth " using domestic garbage incineration flyash and calcining shale production new function material.With great
Environment, economic and social benefit.
The technical scheme is that：A kind of preparation technology of acidic group functional material, it is comprised the following steps that：

Uniformly；
(3) 15~25 parts of water, are added, is placed in net slurry mixer and stirs；
(4), jolt ramming in slurry injection mould；
(5) the mould that slip casting is finished, is coverd with into one layer of heat preservation film, 2 are conserved in the constant temperature weather curing box for being placed in 30~55 DEG C
Form removal after~5 hours；
(6), the block after form removal is placed in dry curing box, acidic group work(is obtained after 12~21d of dry curing at 60~80 DEG C
Can material.
Calcining heat described in preferred steps (1) is 600~800 DEG C；Calcination time is 2~5h.
Grinding sieving described in preferred steps (1) was 100 mesh sieves.
Exciting agent described in preferred steps (2) is the one or more in phosphoric acid, acetic acid or sulfuric acid.
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.
Beneficial effect：
1st, nourishment's time is short, it is possible to decrease the production cycle, there is certain economy；
2nd, flying dust utilization rate is high, and the useless rate of technique profit is big, can high degree realize refuse reclamation；
3rd, product can effectively close the heavy metal in flying dust, while having preferable retaining, water permeability, with certain ring
Border benefit.
