Abstract
A process for preparing humic acid includes such steps as pulverizing peat or weathered coal, adding alkaline solution, stirring, adding ammonium salt, stirring, sealing, reaction baking and pulverizing. Its advantages are simple process, high concentration and low cost.
Description
Technical field:
The present invention relates to a kind of technology for preparing humic acids, belong to a kind of production method of humic acids.
Background technology:
The application of humic acids on agricultural obtained domestic and international expert's abundant affirmation, particularly in the last few years, because the continuous minimizing of fertilizer sowing amount, the organic matter in the soil, corruption were planted matter content and were sharply descended, cause soil compaction, soil fertility to descend, sustainable development of agriculture has been subjected to threat.Humic acids can replenish the organic matter in the soil rapidly, and matter is planted in corruption, reaches the effect of fertilizing soil, enhancement soil fertility.
Traditional technology is produced humic acids, mostly be Sodium salts humic acids, sylvite, its production method is: weathered coal with alkaline purification after, again through clarification, evaporation, concentrate, technological process such as drying just can produce this product, it is bigger to produce the humic acids investment in this way, and technology is complicated, and the cost of product is also than higher simultaneously, this series products is used for producing liquid level more and sprays fertilizer, so purposes is restricted.Another kind of is " the native chemical fertilizer " of rural production in the past---ammonium humate, method be with the carbon ammonium with after weathered coal mixes by a certain percentage, add suitable quantity of water, make its slaking at a certain temperature.Though the humic acids technology of producing with this method is simple, to invest for a short time, the effective constituent of product is extremely low, (solubility humic acids less than 1%), result of use is bad.
Summary of the invention:
The object of the present invention is to provide that a kind of investment is less, technology is simple, steady quality, a kind of technology for preparing humic acids of being convenient to promote.
Purpose of the present invention is implemented by following technical scheme: steps in sequence is: with 1000 parts of peat or weathered coals (by weight), be ground into the powder that particle diameter is not more than 2mm, add 200 parts by weight---300 parts, concentration is 10%---20% strong alkali solution, fully stirred 3 minutes---5 minutes, add 100 parts of weight parts---150 parts ammonium salt then, restir 3 minutes---5 minutes, discharging, with streams closed, temperature remains on 60 ℃-80 ℃, the fully reaction through 36-72 hour, and oven dry, pulverizing are promptly.
Described strong alkali solution can be sodium hydroxide solution, potassium hydroxide solution, sodium pyrophosphate solution.
Described ammonium salt can be bicarbonate of ammonia, primary ammonium phosphate, Secondary ammonium phosphate etc.
Advantage of the present invention is: production technique is simple, with the humic acids of this kind explained hereafter, humic acids content is more than 40%, solubility humic acids content is greater than 20%, and its manufacturing cost reduces greatly, can be used in all many-sides: as making organic fertilizer, organic-inorganic compound fertilizer etc.
Embodiment:
Embodiment 1: a kind of technology for preparing humic acids, and steps in sequence is: with 1000 kilograms of peat or weathered coals, be ground into the powder that particle diameter is 0.5mm, add 200 kilograms of concentration and be 10% sodium hydroxide solution, fully stirred 3 minutes---5 minutes, add 100 kilograms bicarbonate of ammonia, restir 3 minutes then---5 minutes, discharging, with streams closed, temperature remained on 60 ℃, through 72 hours, fully reaction, oven dry, pulverizing are promptly.
Embodiment 2: a kind of technology for preparing humic acids, and steps in sequence is: with 1000 kilograms of peat or weathered coals, be ground into the powder of particle diameter less than 1mm, add 300 kilograms of concentration and be 20% potassium hydroxide solution, fully stirred 3 minutes---5 minutes, add 150 kilograms Secondary ammonium phosphate, restir 3 minutes then---5 minutes, discharging, with streams closed, temperature remained on 80 ℃, through 36 hours, fully reaction, oven dry, pulverizing are promptly.
Embodiment 3: a kind of technology for preparing humic acids, and steps in sequence is: with 1000 kilograms of peat or weathered coals, be ground into the powder that particle diameter is 2mm, add 250 kilograms of concentration and be 25% sodium pyrophosphate solution, fully stirred 3 minutes---5 minutes, add the primary ammonium phosphate of 120 kg, restir 3 minutes then---5 minutes, discharging, with streams closed, temperature remained on 70 ℃, through 48 hours, fully reaction, oven dry, pulverizing are promptly.
