Description

A kind of organic fertilizer process containing high-activity humic acid
Technical field
The present invention relates to a kind of activated humic acid organic fertilizers, especially a kind of to contain using lignite, weathered coal as primary raw material The organic fertilizer of high-activity humic acid.
Background technique
Humic acid is decomposition and conversion and a series of geochemical process accumulation of the animals and plants remains by microorganism A kind of organic substance to get up.Humic acid consists of three parts, and according to its dissolubility in different solvents, is classified as yellow corruption Acid, ulmic acid, humic acid.The molecular weight of fulvic acid is smaller, and active highest, ulmic acid takes second place.And pyrotomalenic acid can reducing substances Person's character is widely present in peat, lignite, in weathered coal, and essential element group becomes carbon, hydrogen, oxygen, nitrogen, sulphur and a small amount of phosphorus. Humic acid has good ion exchange, its functional group is to cationic Na+, Ca in soil2+、Mg2+、Fe3\ ai3+ With anion cr, so42There are very strong exchange capacity and suction-operated (complexing, chelating properties).It is multi-functional organises Object is closed, containing hydroxyl, quinonyl, the more active function groups such as carboxyl have very big internal surface area, there is stronger absorption, hand over It changes, is complexed, sequestering power.It is used as organic fertilizer in agricultural, soil texture can be changed, disease resistance volume increase is played to crops It increases income and reducing power, is the necessity of green agriculture.
The purpose of the present invention is a kind of organic fertilizer containing high-activity humic acid is provided, with brown for existing deficiency among the above Coal, weathered coal or peat be primary raw material, first by raw material crush post activation after, acidification, then three times purify after by It is dry, it is made containing high-activity humic acid organic fertilizer.
Summary of the invention
The object of the present invention is achieved like this, characterized in that realizes as follows.
Step 1: the raw material of humic acid is crushed to 80-100 mesh or so；
Step 2: the humic acid material of crushing is added in stirring mixer, and the nitric acid solution that humic acid weight 1%-5% is added is stirred It mixes, reacts, seals, humic acid powder must be activated；
Step 3: the humic acid powder after activation is added into ethanol solution hydrochloride, adjusts PH to 1-4, is mixed；
Step 4: being added sodium hydroxide solution, is heated to 45-80 DEG C, stands 1-2 hours, and filtering obtains filtrate I；
Step 5: by the filter residue after removal filtrate after pure water rinses, sodium hydroxide solution is added, is heated to 45-80 DEG C, stands 1-2 hours, filtering obtained filtrate II；
Step 6: sodium hydroxide solution will be added in the filter residue after removal filtrate, is heated to 45-80 DEG C, stands 1-2 hours, mistake Filter, obtains filtrate III, and recycle filter residue；
Step 7: merging filtrate I ~ III is added sodium hydroxide solution, enters heating kettle and be stirred, and is heated to 45-80 DEG C, reaction 30 minutes, obtain mixture；
Step 8: the mixture after reaction is 1-2 hours dry in drying machine, obtain high-activity humic acid；
Step 9: high-activity humic acid 50%-60%, urea 5%-10%, ammonium sulfate 5%-10%, magnesium sulfate 3%-5%, sulphur Sour zinc 3%-5%, bentonite 3%-5%, borax rare earth 5%-10%, which proportionally matches, to be got ready, is sent into blender and is mixed It is even；
Step 10: the raw material stirred evenly is crushed by pulverizer；
Feedstock transportation to granulating disc after stirring evenly, crushing is granulated by step 11；
Step 12 sieves the finished product being granulated by screening machine, and underproof finished product continues the mistake Step 10: 11 Journey reprocessing, it is qualified at mouth be delivered to dryer carry out moisture be dried into fertiliser granulates；
Step 13 cools down the fertiliser granulates after drying；
Step 14, the fertiliser granulates product quantitative package envelope that will have been cooled down, storage.
Wherein:
In the production method steps one rich in humic acid raw material be lignite or weathered coal, humic acid content 20-50%,
Nitric acid solution concentration 3%-8% in the production method steps two reacts 20-30 minutes, seals 10-15 days,
Ethanol solution hydrochloride is mixed by 10% ethanol solution and 30% hydrochloric acid solution in the production method steps three, salt used The volume of sour ethyl alcohol is 10-20 times for activating humic acid weight, and mixing time is 10 20 minutes.
The concentration of sodium hydroxide solution is 1.5% in the production method steps four, and the volume of sodium hydroxide solution used is 10-20 times of raw material weight.
The concentration of sodium hydroxide solution is 2.0% in the production method steps five, and the volume of sodium hydroxide solution used is 15-25 times of raw material weight.
The concentration of sodium hydroxide solution is 2%-3.5%, the body of sodium hydroxide solution used in the production method steps six Product is 10-15 times of raw material weight.
The concentration of sodium hydroxide solution is 5.0% in the production method steps seven, and the volume of sodium hydroxide solution used is 5-10 times of raw material weight.
It is dried 1-2 hours at 55 DEG C 60 DEG C of dryer temperature in the production method steps eight.
The invention has the advantages that its essential element group becomes carbon, hydrogen, oxygen, nitrogen, sulphur and a small amount of phosphorus.Humic acid tool There is good ion exchange, its functional group is to cationic Na+, Ca in soil2+、Mg2+、Fe3\ ai3+And anion cr、so42There are very strong exchange capacity and suction-operated (complexing, chelating properties).It is multi-functional organic compound, is contained Hydroxyl, quinonyl, the more active function groups such as carboxyl have very big internal surface area, there is stronger absorption, exchange, complexing, chela Conjunction ability.It is used as organic fertilizer in agricultural, soil texture can be changed, disease resistance increasing both production and income and reduction are played to crops Ability is the necessity of green agriculture.
