Technical field
The present invention relates to field of refuse resource utilization, particularly to a kind of side utilizing waste incineration slag to manufacture building materials
Method.
Background technology
Along with rapid development of economy and the raising day by day of living standards of the people, house refuse sharply increases, by city to
Vast rural area is spread, and increasingly threatens the living environment of the mankind.Administer rubbish the most cost-effectively, prevent the pollution of the environment,
Become the pressing issues that the whole society needs to solve.Especially because the place that can be used for dumping is limited, the one-tenth of garbage loading embeading
This increase, burning and the comprehensive utilization of rubbish are more and more paid attention to by people.
Chinese invention patent CN103769287B discloses one way of life waste incineration slag and crushes, sort and recycle work
Skill: garbage slag, after tramp iron separator, injects disintegrating machine formation stream together with water, under material stream action of gravity, by broken
Broken machine, jigging machine and screening installation, it is thus achieved that preferred slag material, after absorption cell and sedimentation tank filter, dry filtering residue is used for mixing
The raw materials such as solidifying soil.This invention achieves the sorting to waste incineration slag and recycling in theory, but lacks not in its technique
The process of the bulk rubbish such as the textile that burns completely, plastics, these not removed bulk rubbish are difficult to pulverize in disintegrating machine,
And follow-up entrance sedimentation tank, it is directly used in the raw materials such as concrete after drying, causes concrete quality to be deteriorated, bring potential safety hazard.
Summary of the invention
The invention discloses a kind of method utilizing waste incineration slag to manufacture building materials, it is possible to solve above-mentioned prior art and ask
One or more in topic.
According to an aspect of the invention, it is provided a kind of utilize waste incineration slag manufacture building materials method, including with
Lower step,
S1. waste incineration: rubbish is inserted incinerator and carries out centralized burning；
S2. except ferromagnetism goods: utilize magnet apparatus to inhale the ferromagnetism goods selecting in slag；
S3. except bulk impurity: use sieve sieve to remove unburned bulk impurity completely in slag；
S4. iron powder screening: by sieve leaks down slag pulverize, add water and stir into serosity, use concentration equipment
Select the iron powder in serosity；
S5. heavy metal screening: remove the serosity after iron powder and enter heavy metal screening plant, wash in a pan out heavy metal therein；
S6. precipitate standby: wash in a pan the serosity after taking heavy metal and flow to sedimentation tank and precipitate, the stove in periodic cleaning sedimentation tank
Slag mud, and transport at building materials manufacture standby.
The invention has the beneficial effects as follows, after waste incineration, reclaim major part bainite article and heavy metal in slag, screen out big
Block impurity.The method of the present invention, has saved resource, improves the recycling rate to rubbish, has gone out the big portion in slag
Point impurity, improves the cleanliness factor of slag for manufacturing building materials, decreases the pollution to environment.
In some embodiments, in step S1, incinerator is connected with electromotor, and the energy after waste incineration is used for generating electricity.
Thereby, it is possible to the saving energy.
In some embodiments, in step S3, bulk impurity particle diameter is more than 3cm.Thus, major part bulk can be sieved
Impurity.
In some embodiments, in step S4, concentration equipment is magnetic platform, and serosity can be sprawled on magnetic platform
Open.Thus, improve the contact area with serosity, thus improve the screening to iron powder and the response rate.
In some embodiments, in step S4, the iron powder in serosity is by magnetic-adsorption on magnetic platform, and remaining is starched
Liquid flows away from platform, enters heavy metal screening plant.Hereby it is achieved that the screening to iron powder.
In some embodiments, step S4 also includes, the iron powder periodically scraping with scraper and reclaiming on magnetic platform.
Thus, can reclaim iron powder, on minimizing magnetic platform, covering is to the screening effect of iron powder in follow-up serosity.
In some embodiments, in step S6, sedimentation tank is at least one, and sedimentation tank is arranged in order.Thus, can basis
Precipitation needs to precipitate serosity.
In some embodiments, in step S6, sedimentation tank is 5.Thereby it is ensured that to the precipitation effect of slag mud in serosity
Really.
In some embodiments, in step S6, the supernatant in sedimentation tank is collected as mixing water in step S4.
Thus, the water in sedimentation tank is circulated utilization, economizes on resources and cost.
In some embodiments, slag mud is cleaned out from sedimentation tank, after being dried, then transport at building materials manufacture.
Thus, convenient after drying other building materials carry out proportioning and mix slag mud with Calx, cement and sandstone etc..
Accompanying drawing explanation
The flow chart of the method utilizing waste incineration slag manufacture building materials of Fig. 1 position one embodiment of the present invention.
Detailed description of the invention
The present invention is further detailed explanation below in conjunction with the accompanying drawings.
The waste incineration slag that utilizes that Fig. 1 show schematically show according to one embodiment of the present invention manufactures building materials
Method.Comprise the following steps:
