Abstract
The invention provides a production technology for coal humic acid for lead-acid cell, comprising disintegrating coal to granule with the size to be 0.5mm, then adding sodium-hydroxide and mixing intimately, heating for 2~2.5 hours, cooling, then adding water with the consumption of four times than the stock in mass, stirring, stewing, extracting supernatant and adding hydrochloric acid solution slowly to supernatant, mixing intimately until the pH value drops to 2, stewing and the residue is the humic acid. Then adding the humic acid and water into autoclave, stirring, adding sulfuric acid solution slowly to autoclave, mixing intimately, stewing for reaction for 24 hours, washing the residue with fresh water until the pH value is6~7, getting the residue out, drying, disintegrating and getting the product. The invention is characterized by the simple process, non pollution, low cost for extraction and high extraction rate, and can be applied extensively.disintegrating and getting the product.
Description
Technical field
The invention belongs to a kind of coal humic acid production technology that is used for lead storage battery.
Background technology
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.Found at present also can use high-technology field through the purified humic acids, make the battery plate swelling agent with humic acids and can improve the store battery cold starting performance, improve electrical capacity and superpotential, prevent the contraction of pole plate paste effectively and peel off the work-ing life of prolongation store battery.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 coal humic acid production technology that is used for lead storage battery, make it have features simple and practical process, free from environmental pollution, extraction cost is low, speed is fast, the advantage that extraction yield and product purity are high.For this reason, a kind of coal humic acid production technology that is used for lead storage battery, 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 8～12 hours, taking precipitate is humic acids;
(3), press humic acids: sulfuric acid: the proportioning raw materials of water=2: 3: 3, earlier humic acids and water are joined in the reactor, after stirring, the sulphuric acid soln that slowly adds proportional quantity again, mix, standing and reacting precipitation 24～30 hours, taking precipitate is 6～7 with clear water rinsing to this sedimentary pH value;
(4), this throw out is taken out, oven dry, pulverize and get product.
Described standing and reacting temperature is 96 ℃～98 ℃.Described bake out temperature is 110 ℃～120 ℃.Described sulfuric acid concentration is 40～50%.
Advantage of the present invention is to have features simple and practical process, free from environmental pollution, extraction cost is low, it only is 60% of traditional method cost, high more about 40% than traditional method for extracting rate, make in the dna purity humic acids iron ion reduce to 0.004%, than fast nearly 10 times of the extraction rate of traditional method, the tool product is longer more than 2 times than the product life of the extraction of traditional method work-ing life, and good prospects for application is arranged.
Embodiment
The present invention adopts enamel reaction still, vertical response pot all can.Can make the cylindrical form reactor by oneself for saving cost, reactor placed and stuck-at-.5 rice * about 1.5 meters platform on, platform is just made with round steel or triangle, and hand steered ladder is arranged, being convenient to operator operates up and down, the reactor top is the stirrer of 0.55～0.75kw with the parallel bracket constant power, the diameter of rotating shaft is 30 centimetres, have oar shape or foliate impeller below, the kettle lower end with 2 cun pipelines that have a valve about 1 meter as delivery pipe, 2 little progress water pipes are inserted in the upper end, and feed 1 cun steam inlet tube, and the air inlet mouth of pipe is from reaching at the bottom of the still about 1 chi, and type of heating is the steam direct heating.
Described dryer is a roller dryer, and dryer is bought or self-control all can.
Brown coal 100Kg joined be broken into the particle that granularity is 0.4mm in the pulverizer.The sodium hydroxid of above-mentioned raw materials with 10Kg is mixed to join in the reactor, stirs, 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 440Kg, after stirring, staticly settled 10 hours, and got supernatant liquor, remove throw out, in supernatant liquor, slowly add hydrochloric acid soln, mix, constantly measure and reduce to 2 until the pH value of supernatant liquor, stop to stir, staticly settled 10 hours, taking precipitate nearly weighs 30Kg, is humic acids.Humic acids 30Kg and water 45Kg are joined in the reactor, after stirring, slowly add concentration again and be 45% sulfuric acid 45Kg, mix, standing and reacting precipitation 24 hours, the standing and reacting temperature is 97 ℃.Taking precipitate is 6.5 with clear water rinsing to this sedimentary pH value.This throw out is taken out, and oven dry, bake out temperature are 110 ℃, are crushed to 0.01 millimeter of particle diameter, promptly get the finished product of about 28Kg.
In a word, features simple and practical process of the present invention, free from environmental pollution, extraction cost is low, and the extraction yield height can be promoted the use of.
