Abstract
The invention discloses a process method for producing a building gelling agent from industrial residues. The gelling agent consists of an activating agent, gypsum, cement clinker and cinder, wherein the activating agent consists of alumina-containing residues, lime sludge and alkali metal sulphate residues. The process method comprises the following steps of: drying 1-50 percent by weight of alumina-containing residues, 1-50 percent by weight of alkali metal sulphate residues and 2-90 percent by weight of lime sludge, smashing and sieving till the particle size is smaller than 5 millimeters; mixing to obtain the activating agent; smashing blast furnace grain slag and pulverized fuel ash in the weight ratio (80-100):(0-20), sieving and mixing to obtain cinder; and adding the activating agent, gypsum, cement clinker and the cinder into a ball mill in the weight ratio 4:4:(8-30):(84-62) for milling till the surface area is 420-500 m<2>/g. According to the process method, industrial residues are fully utilized, the quality of the gelling agent can be ensured, the production cost of the gelling agent for buildings is lowered, fuel consumption is eliminated, energy resources are saved, and environmental pollution is avoided.
Description
Technical field
The present invention relates to material of construction, especially relate to a kind of processing method that can replace the building jelling agent of cement with industrial residue production.
Background technology
1824 British A Sipuding (Joseph Aspdin) be fired into cement with Wingdale and clay, nearly two over 100 years, manufacture of cement adopts Wingdale and coal always, adopt the one firing technique production of two mills, consume a large amount of energy, discharge a large amount of greenhouse gases carbonic acid gas, havoc environment.In producing cement, also addition portion is divided iron-smelting blast furnace grain slag and flyash at present, but adding proportion seldom.If increase blast furnace granulated slag or flyash usage quantity, will directly add materials such as NaOH, organic amine, calcium chloride, salt, so not only increase cost, and bring the harmful elements such as the organic and chlorion that is corrosive that are unfavorable for later strength into, quality is wayward.
Summary of the invention
Add the problem of blast furnace granulated slag and flyash equal industrial residue existence at manufacture of cement in the above-mentioned prior art, the invention provides a kind of industrial residue that utilizes and to produce the building jelling agent that replaces cement, neither need consume fuel, can not discharge the processing method of carbon dioxide greenhouse gas again.
The technical scheme that the technical problem to be solved in the present invention is taked is: the described building jelling agent of producing with industrial residue is made up of promoting agent, gypsum, cement clinker and slag, described promoting agent is made up of salic waste residue, lime mud and alkali metal sulfates waste residue, described slag is blast furnace granulated slag or blast furnace granulated slag and mixture of fly ash, and is prepared from by following processing method:
(1) become granularity less than 5mm the salic waste residue of 1-50%wt, the alkali metal sulfates waste residue of 1-50%wt and the dry respectively crushing and screening of lime mud of 2-90%wt earlier, again it be mixed and made into promoting agent,
(2) the dry crushing and screening of blast furnace granulated slag is made slag, or is to be mixed and made into slag behind the blast furnace granulated slag of 80～99 ﹕ 1～20 and the dry crushing and screening of flyash weight ratio,
(3) be that the promoting agent, gypsum, cement clinker, slag of 4 ﹕, 4 ﹕, 8 ~ 30 ﹕ 84 ~ 62 adds ball mill and carry out ground and mixed again with weight ratio, make its surface-area reach 420 ~ 500 ㎡/g.
Described salic waste residue is preferably calcined aluminium vanadine waste residue, aluminum oxide waste residue.
Described alkali metal sulfates waste residue is meant at industrial anhydrous sodium sulphate, vitriolate of tartar waste residue.
Described blast furnace granulated slag can be used as the fine cement raw material owing to have potential hydraulic gelling property; Described flyash is to receive the thin ash of catching the flue gas behind coal combustion, flyash is one of bigger industrial residue of the current discharge capacity of China, along with development of electric power industry, the flyash quantity discharged of coal-burning power plant increases year by year, a large amount of flyash does not add processing, will produce airborne dust, atmosphere pollution, if entering water system can cause the river to silt up, and toxic chemical substance wherein also can work the mischief to human body and biology; Described salic waste residue is preferably calcined bauxitic clay waste residue and aluminum oxide waste residue, the calcining bauxitic clay is mainly used in the High Alumina Porcelain high-abrasive material, industrial ceramics etc., to the aluminium sesquioxide content requirement than higher, to influencing the whiteness iron level strict restriction is arranged, often the bauxitic clay that aluminium sesquioxide content in calcining back is low and iron content is high is just discarded, serious waste calcinating fuel and influence environment; The present invention is preferably generating product processes such as chemical fibre such as viscose fiber or formic acid, a large amount of industrial residue sodium sulfate of generation.This waste residue is on the low side or contain some impurity odorous because of purity, influence its again other field use direct landfill or stack and influence environment often.
Bare bones of the present invention utilizes the Na2SO4(K2SO4 in the alkali metal sulfates waste residue) and CaO in thing hydration process generation chemical reaction of the present invention, generate contain NaOH(KOH) and the promoting agent of CaSO4, NaOH and CaSO4 can excite blast furnace granulated slag or blast furnace granulated slag and flyash, make it have potential hydraulic gelling property, the calcining bauxitic clay contains a large amount of activated aluminas, generate calcium aluminate with Ca (OH) 2 reactions, can improve early stage resistance to compression of the present invention and anti-folding rapidly and wait physical strength, can replace cement to be used for building.The present invention has made full use of industrial residue, turns waste into wealth, and can not only guarantee the jelling agent quality, reduces gelling agent production cost for building, and does not need consume fuel, has saved the energy, does not pollute the environment again, is a kind of novel environment-friendly type building jelling agent.
The relevant portion chemical equation is as follows:
HCOONa+H2SO4=HCOOH+Na2SO4
Na2SO4+Ca(OH)2=2NaOH+?CaSO4。
