Abstract
A process for preparing the green ecological fertilizer from weathered coal includes such steps as pulverizing, mixing it with sodium hydroxide, stirring, heating cooling, mixing with water, stirring, depositing, taking supernatant, regulating pH=2, depositing, taking deposit, pulverizing to obtain humic acid, mixing it with P, N, K, B, Na, Ca, Fe, Ma and Mg, ginding and granulating.
Description
Technical field
The invention belongs to a kind of technology of producing green ecological fertilizer with coal humic acid.
Background technology
China is large agricultural country, expends a large amount of chemical fertilizer every year, but the volume increase of the increase of chemical fertilizer usage quantity and farm crop is disproportionate, the often increase of chemical fertilizer usage quantity, cause the hardening soil on the contrary, the decline of crop yield, this is because chemical fertilizer utilization ratio is low, fertilizer efficiency descends.According to side examination China chemical fertilizer utilization ratio is about 35% only, is lower than 55% of developed country.Humic acids is a kind of natural organic high molecular compound, is that a kind of multi-functional chemical materials has wide industrial and agricultural use, is used for aspects such as forestry, animal husbandry and medicine in a large number.It has wide industrial and agricultural use as a kind of multi-functional chemical materials for it, also is used for forestry, animal husbandry, livestock industry aspect in a large number.But it is undesirable only to make effect of fertilizer with humic acids, and traditional extraction process is comparatively complicated, and extraction yield is low, the extraction cost height, and extraction rate is slow, and product contains a large amount of impurity, contaminate environment.
Summary of the invention
The purpose of this invention is to provide a kind of technology of producing green ecological fertilizer with coal humic acid, make it have features simple and practical process, free from environmental pollution, extraction cost is low, extraction yield and the high advantage of fertilizer efficiency utilization ratio.For this reason, a kind of technology of producing green ecological fertilizer with coal humic acid, it is to be made of following technological process:
(1), with weathered coal, or brown coal, or mud coal joins in the pulverizer, is broken into the particle that granularity is 0.2~0.5mm;
(2), press coal: sodium hydroxid=8~12: 0.5~1.2 proportioning raw materials, above-mentioned raw materials is mixed to join in the reactor, stir, begin to be heated to 89 ℃~92 ℃, heat and stop heating after 2~2.5 hours, treat that raw material is cooled to 20 ℃~30 ℃ and adds the water that accounts for 4 times of raw material weights again, after stirring, staticly settled 8~12 hours, get supernatant liquor, remove throw out, in supernatant liquor, slowly add hydrochloric acid soln, mix, reduce to 2 until the pH value of supernatant liquor, staticly settled taking precipitate 8~12 hours;
(3), this throw out is taken out; oven dry; it is humic acids that pulverizing promptly gets; again by following weight proportion raw material: 30~40 parts of humic acidss, 16~21 parts of organophosphoruss, 1~3 part in nitrogen, 30~43 parts in potassium, 0.01~0.09 part of boron, 0.9~2 part in sodium, 0.9~3.5 part of calcium, 1.1~4.1 parts of iron, 0.15~1 part in manganese, 2.59~5.3 parts in magnesium; said ratio material separated pulverizing is pulverized; mix, get product with the tablets press granulation.
Advantage of the present invention is to have features simple and practical process, and free from environmental pollution, extraction cost is low, only is 70% of traditional method cost, than traditional method for extracting rate high about 50%.Contain required mineral substance of various plants and trace elements etc. among the present invention, the fertilizer efficiency performance is permanent, the structure of effectively improving the soil, reduce volume weight of soils, the also corresponding increase of soil cell size has strengthened the permeability of soil, chemical fertilizer utilization ratio is 55%, has improved the output of farm crop.
Embodiment
The present invention adopts enamel reaction still, vertical response pot all can.Described dryer is a roller dryer, and dryer is bought or self-control all can.
Weathered coal 200Kg joined be broken into the particle that granularity is 0.3mm in the pulverizer.The sodium hydroxid of above-mentioned raw materials with 20Kg is mixed to join in the reactor, stir, begin to be heated to 90 ℃, heat and stop heating after 2.1 hours, treat to add again when raw material is cooled to 25 ℃ the water of 880Kg, after stirring, staticly settled 10 hours, get supernatant liquor, remove throw out, in supernatant liquor, slowly add hydrochloric acid soln, mix, constantly measure and reduce to 2, stop to stir, staticly settled 10 hours until the pH value of supernatant liquor, taking precipitate nearly weighs 60Kg, this throw out is taken out, oven dry, it is humic acids that pulverizing promptly gets.Get humic acids 33.3Kg, organophosphorus (P again
2O
5) 19Kg, nitrogen 1.27Kg, potassium (K
2O) 37.77Kg, boron 0.05Kg, sodium 1.09Kg, calcium 1.58Kg, iron 2.1Kg, manganese 0.25Kg, magnesium 3.59Kg, said ratio material separated pulverizing is pulverized (crossing 100 mesh sieves) mixes, and promptly gets about 100Kg finished product with the tablets press granulation.
Organophosphorus of the present invention selects for use Vanadium Pentoxide in FLAKES, nitrogen to select for use nitrogen peroxide, potassium to select for use potassium oxide, boron to select for use boric acid, sodium to select for use yellow soda ash, calcium to select for use calcium oxide, iron to select for use ferric oxide or ferric oxide, manganese to select for use Manganse Dioxide, magnesium to select magnesium oxide for use.
In a word, features simple and practical process of the present invention, free from environmental pollution, production cost is low, contains required mineral substance of various plants and trace elements etc., and the fertilizer efficiency performance is permanent, and the structure of effectively improving the soil can be promoted the use of.
