Description

A kind of utilization method of organic matter in ardealite
Technical field
The present invention relates to the resource utilization fields of industrial residue, and in particular to the side of organic matter is recycled from ardealite Method, it can also be used to recycle organic matter from other industrial by-products.
Background technique
Gypsum is sulfate mineral, chemical molecular formula CaSO4·xH2O.Gypsum is divided into the natural gypsum and industrial by-product Gypsum.Currently, industry by-product gypsum is mainly ardealite, desulfurized gypsum and titanium gypsum.
Ardealite is the by-product of phosphoric acid by wet process industry, and 1 ton of phosphate fertilizer of every production is (with P2O5Calculate) about generate 4.5~5.0 tons Ardealite.According to statistics, China's ardealite discharge amount in 2014 is up to 80,000,000 tons, and the heap of ardealite high-volume, adds up super over the years Cross 300,000,000 tons.In the whole country, the comprehensive utilization ratio of China's ardealite in 2015 is only 30%.Remaining gypsum is stacked nearby, enterprise Industry spends a large amount of funds for building cinder field and its operational management thus every year.Ardealite containing undecomposed phosphorus ore, free phosphoric acid, The impurity such as fluoride, a large amount of stack can bring environmental problem, contaminated soil, atmosphere and water body.How it is rationally located in Setting and handling is major issue that it is faced.
Organic matter is ethylene glycol monomethyl ether acetate, different sulphur cyanogen methane, 3-methoxyl group pentanes, 2-ethyls-1 in ardealite , 3- dioxolane.For organic matter mainly with physical absorption formal distribution on gypsum crystal surface, content is about 0.1%~0.2%. It make cement setting time extension, day compression strength of strength reduction, especially 28 have it is biggish decline [Zhang Jianxin, Peng Jiahui, The measurement of organic matter and its influence [J] the Sichuan University journal (engineering science to cement performance in Wan Tizhi ardealite Version), 2006,38(3): 110-113].
Biogas be organic substance under anaerobic, a kind of mixed gas generated by the fermentation of microorganism. The main component of biogas is methane.Biogas is by 50%-80% methane (CH4), 20%-40% carbon dioxide (CO2), 0%-5% nitrogen (N2), the hydrogen (H less than 1%2), the oxygen (O less than 0.4%2) and 0.1%-3% hydrogen sulfide (H2The gas compositions such as S).Biogas Main component methane is a kind of ideal gaseous fuel, its colorless and odorless can burn after mixing with appropriate air.Every cubic metre The calorific value of pure methane is 34000 kilojoules, and the calorific value of every cubic metre of biogas is about 20800-23600 kilojoule.I.e. 1 cubic metre After biogas completely burned, the heat that the offer of 0.7 kilogram of anthracite is provided can be generated.Compared with other combustion gas, the capability of antidetonance It preferably, is a kind of good clean fuel.
Although many researchs all propose, organic matter can be removed by flotation, flotation is less using what medicament report. In addition the organic matter floatingly selected recycle report it is also less.
Organic matter in ardealite can be used as the raw material of biogas according to its feature after collection.
Summary of the invention
In order to solve the problems existing in the prior art, the present invention provides a kind of utilization methods of organic matter in ardealite, together Prior art scheme is compared, and this method can save production cost, is improved efficiency, and realizes resource circulation utilization.Phosphorus can be significantly improved Gypsum product quality has significant economic benefit and social benefit.
A kind of utilization method of organic matter in ardealite, comprising the following steps:
Water, gypsum modifying agent, foaming agent and inhibitor is added after mixing evenly in ardealite, blasts air in the solution and obtains Organic foam collects organic foam.Wherein, the quality of water is the 100-500% of phosphogypsum quality；Gypsum modifying agent changes for albumen Property agent, fatty modifier, one of sulfonated melamine compound resin, additional amount is the 0.1-1.0% of phosphogypsum quality；It rises Infusion are as follows: one of methanol, terpenol, sec-octyl alcohol, methyl anyl alcohol, triethoxybutane, pyridine, hydrocarbyl sulfonic, carboxylic acid add Enter the 0.1-1.0% that amount is phosphogypsum quality；Inhibitor is one of starch and dextrin, and additional amount is phosphogypsum quality 0.1-1.0%。
Acid neutralizing agent, pH stable agent, microorganism and carbon source, sealed fermenting are added in organic foam to react to obtain natural pond Gas.Wherein, acid neutralizing agent is one of lime, carbide slag, and additional amount is the 0.5-5.0% of phosphogypsum quality；PH stable agent For one of lime stone, marble, chalk, additional amount is the 0.5-5.0% of phosphogypsum quality.
Described protein modified dose is prepared for animal protein, and fatty modifier is prepared for animal tallow.
The microorganism includes zymogenic bacteria, hydrogen-producing acetogens, consumption hydrogen acetogen, food producing hydrogen and methane bacterium, food Acetic acid and methane producing bacterium.
The carbon source includes straw, people and animals' excreta.
Water and ardealite after defoaming, are separated by filter press, after filtrate lime or carbide slag neutralization are neutrality It recycles, ardealite is used for building materials field.
Compared with the existing technology, the invention has the following advantages that
Organic matter is often adsorbed in ardealite surface, to influence gypsum performance.Gypsum modifying agent is added in ardealite, gypsum changes The adsorption capacity of property agent and gypsum is stronger, and organic matter is exchanged from gypsum surface.In addition, property of the gypsum modifying agent to cement It can influence smaller.Protein modified dose, lime or sodium hydroxide are added in animal protein, is prepared after heating reaction.Rouge Lime or sodium hydroxide are added in animal tallow, is prepared after heating reaction for fat modifying agent.Sulfonated melamine compound tree Rouge is the product that melamine is condensed by sulfuric acid sulfonation, again with formaldehyde.
Foaming agent mainly reduces the surface tension of water, this foaming agent is common foaming agent, is easy to get with raw material, cheap The characteristics of.
Ardealite often contains a small amount of amorphous silicon di-oxide and iron oxide, is easy when blasting air on bubble Floating, inhibitor, which is added, can avoid its floating, reduce the impurity content of organic matter.
The generally aobvious acidity of ardealite, acid condition will affect the growth of microorganism, acid neutralizing agent be added, pH value of solution is adjusted Value is conducive to microorganism growth.
PH stabilizer can be such that organic scum stablizes in neutral environment, be conducive to the growth of microorganism.
Microorganism is the common microorganism for generating biogas, includes: zymogenic bacteria, hydrogen-producing acetogens, consumption hydrogen produce acetic acid Bacterium, food producing hydrogen and methane bacterium, food acetic acid and methane producing bacterium.These microorganisms adapt to the toxicity of ardealite organic matter by domestication. The organic matter that 100kg ardealite generates, the sum about 10 that microorganism is added8It is a.
Carbon source is straw, people and animals' excreta, can provide nutrition for microorganism, promote the generation of biogas.
