Description
Technical field
The present invention relates to solid waste resource comprehensive utilization and utilize technical field, be specifically related to a kind of with PO saponification waste residue,
The method that autoclaved fly ash brick is prepared in refuse-burning plant slag and flying dust hydration.
Background technology
PO saponification waste residue is the saponifying process process using chlorohydrination to produce expoxy propane (propylene oxide, PO)
A kind of garbage of middle discharge, often produces the expoxy propane of 1 t, and the waste residue of the chloride saponification waste-water and 2 t that there are about 40 t produces,
Yield is relatively big, and does not still have clear and definite processing mode at present.PO saponification waste residue is canescence Gypsum Fibrosum shape, and granule is the trickleest, equal
Even, density is relatively light, has the advantages that basicity is high, salt content is high and COD is high.The main component of PO saponification waste residue is Ca (OH)2With
CaCl2, be equivalent to Ca (OH)2The carbide slag that content is relatively low, has certain reference function in technology produces, can be as production
The raw material of building materials.The most at home, the general utilization ways of carbide slag makes construction material, as useful waste residue is joined with flyash
Material produces the research of cement, prepares sintering free construction brick with waste residue with cinder or flyash.In addition to making construction material, carbide
Slag also can be as roadbed raw material, and waste residue-flyash is the most qualified as roadbed material, has the spy that the construction period is short, efficiency is high
Point, and road cost can be reduced, reduce the garbage harm to environment.Can be additionally used in and process acid waste gas and waste water, with
And be applied to produce series general chemical product.Carbide slag and sodium silicate react generation calcium silicates, meeting after calcium silicate hydrate solidification
There is the strongest water resistance.Carbide slag or PO saponification waste residue are incorporated in cement concrete, can make its Ca (OH)2Concentration increases
Add, effectively shorten the setting time of cement, improve rupture strength and the comprcssive strength of cement early metaphase.
Refuse-burning plant slag and flying dust are the solid waste produced after waste incineration and generating electricity, are Disposal of City Domestic Garbages
After primary product.In recent years, along with the quickening of Development of China's Urbanization, China's domestic waste is increasing.Current rubbish
Annual production has reached more than 200,000,000 ton, and annual just with the speed increment of 8%-10%.According to statistics, China's municipal refuse annual production in 2004
It is 1.55 hundred million tons, has reached 2.64 hundred million tons by 2010, it is contemplated that to reaching 4.09 hundred million tons during the year two thousand thirty, and 5.28 will be reached to the year two thousand fifty
Hundred million tons.The house refuse that quantity is the hugest, if the most in addition rationalization processes, not only can take substantial amounts of land area, also can
Certain pressure is caused to environment.At present the most at home or even in the world, to the disposal of rubbish with landfill, compost and 3 kinds of sides of burning
Formula is main.When carrying out garbage disposal according to minimizing, innoxious, resource principle, wherein burning electricity generation method reduction is
For substantially, rubbish volume reduction 80% ~ 90% after burning, can be made, and the heat energy that available waste incineration produces is used for generating electricity.Burn and produce
Solid waste in about 80% be slag, 20% is flying dust.Disposal to dregs of incinerator and flying dust typically uses burying method, still needs to
Take large-area soil.Additionally, the intake of solid waste is grown with each passing day by building material industry, refuse-burning plant slag and flying
Ash is the trend gradually risen for building material industry.Slag, as the substitution material of portland cement, can improve concrete
The intensity of material, performance and durability.Flying dust is then the fine ash trapping in refuse-burning plant incineration flue gas, owing to it contains
Have a certain amount of heavy metal to limit its applied research, therefore cured be to refuse-burning plant flying dust maximally efficient one
Plant and select.Slag and flying dust has been had to be applied to portland slag cement, plastic concrete goods, pavior brick and flyash at present
The production of the products such as brick, this is the preferable direction of comprehensive utilization of slag.Within 2007, Xin Liji (Beijing) building materials company limited starts
Pavior brick, insulating powder coal-dust brick etc. is prepared, achieved with successful experience with slag.Additionally, Suzhou City's universe space building material has
Limit company, three enterprises of Taicang Hua Sheng novel wall material company limited and Hao Yu building materials company limited of city of Kunshan are utilized respectively
Domestic waste incineration residue produces non-burning brick, achieved with demonstration, and operation of going into operation.But flying dust integrated application is in steamed pressurized ash coal
Ash brick is the rarest as the report of aggregate.
Currently, autoclaved fly ash brick does one's utmost the building material advocated, vigorously support as country, have light-duty, permeable and
Feature and the good mechanical performance such as ventilative, be applied not only to construction material and inner-outer wall, may also be fabricated which ecological permeable bricks, extensively use
In ground surface works such as flood control the bank protection walling such as seawall, Bang Shan highway and pier storage yard, park, gardens etc..This project utilizes PO
Saponification waste residue, refuse-burning plant slag prepare autoclaved fly ash brick with flying dust hydration steam pressure, can digest PO saponification waste residue, flying dust etc.
Almost cannot process and exist the solid waste of pollution at present, eliminate the pressure that environment is produced by solid waste, save soil
Ground resource, protects environment, turns waste into wealth, it is achieved the recycling of solid waste, has high environmental benefit, social effect
Benefit and economic benefit, be that a kind of merit is in current, the cause of profit is in the future thousands of years.
Summary of the invention
The present invention provides a kind of and prepares autoclaved fly ash brick with PO saponification waste residue, refuse-burning plant slag with flying dust hydration
Method, it is possible to the problem effectively solving PO saponification waste residue, refuse-burning plant slag and flying dust solid waste comprehensive utilization of resources.Many
