Abstract
The invention provides a method for producing fulvic acid potassium by furfural residue and biological ash. The method comprises the following technical processes of: adding raw materials comprising biological ash powder, furfural residue powder, alkali product and water according to a weight ratio of biological ash powder to furfural residue powder to alkali product to water of 100: (150-200): (5-10): (750-1200) into a reaction kettle, stirring uniformly, heating to 89-91 DEG C, stopping heating after the heating is performed for 2-2.5 h, standing for depositing, and obtaining reaction sediment and reaction supernate after the reactant in the reaction kettle stands for delamination; taking the reaction supernate, adding a hydrochloric acid solution into the reaction supernate slowly, mixing uniformly until the pH value of the supernate is reduced to 2, standing and depositing for 8-12h, taking the supernate sediment and drying to obtain the finished product of fulvic acid potassium. An fertilizer including potassium and humic acid can be obtained by taking the reaction sediment, putting into a sedimentation basin, uniformly mixing the raw material comprising the reaction sediment and the humic acid according to a weight ratio of 1: (0.5-0.8) standing for 2-3h, and then granulating the mixture by spraying. The method for producing fulvic acid potassium by furfural residue and biological ash has the advantages of waste recycling, no environment pollution, no wasting of resources, simple and practical technology, low extraction cost, and is capable of being popularized and used.
Description
Technical field
The invention belongs to the environmental friendly regenerated technical field of utilizing of trade refuse, relate to a kind of method of producing potassium fulvate with furfural dregs and biological power plant biomechanical gray.
Background technology
China is large agricultural country, the chemical fertilizer of annual labor, but the raising the output 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.Be merely about 35% according to side examination China chemical fertilizer utilization ratio, be lower than 55% of developed country.
Furfural dregs is an industrial residue of producing furfural, and it contains xanthohumic acid 24%-30%, quick-acting nitrogen 0.04%, and available phosphorus 0.56%, pH value 1.90 is the fertile resources of a kind of good corruption.Can be used to make biological organic synergistic fertilizer, biological active synergistic fertilizer, culture medium of edible fungus etc.Biomechanical gray is the ash that produces behind the cigarette ash, burning plants in the flue gas that is produced behind the coal combustion, contains effective potassium about 8%, and it is very big in the annual output of China, as not handling, then can cause atmospheric dust pollution, enters water body such as lake, river and also can cause water to pollute.Just can be used to produce potassium fulvate if both are carried out proportioning through certain process, realized the comprehensive utilization of resource, reached certain economic benefits.
Agriculturally, the soil but the potassium fulvate activation is hardened promotes the physiological metabolism of various gourd, fruit and vegetables and land for growing field crops farm crop; Promote well developed root system, cauline leaf is in great numbers, can make the crop ripen in advance about ten days; Raising the output belongs to the energy-conservation fertilizer of green high-efficient more than 20%, has the characteristic of quick dissolved, quick effect; Can effectively kill various subterranean pest-insects, to the special efficacy that has of prevention root knot nematode disease, be the required a kind of ultra-high efficiency of friend peasant, the new bio-fertilizer of ultra concentrated.Also can be used as foliage fertilizer, towards the host or the additive of fertilising, fertilizer or fertilizer.
In industrial aspect, potassium fulvate is used for cement water reducing agent, and also as the oil drilling slurry treatment agent, in addition, potassium fulvate also is widely used in briquetting to the xanthohumic acid goods, foundry sand sticker etc.
Summary of the invention
The purpose of this invention is to provide a kind of method of producing potassium fulvate, make it have regenerated resource development and utilization with furfural dregs and biomechanical gray, free from environmental pollution, powerlessness waste, features simple and practical process, the advantage that extraction cost is low.For this reason, the present invention is made up of following technological process:
(1), collection of biological ash, sieve, impurity elimination, biological ashes;
(2), furfural dregs is sieved, impurity elimination is put in the shredder, and grinding to form granularity is the grain powder of 0.1～0.3mm, processes the furfural ground-slag;
(3), by biological ashes: furfural ground-slag: alkaline substance: the raw material weight proportioning of water=100: 150～200: 5～10: 750～1200; Above-mentioned raw materials is mixed to join in the reaction kettle, stirs, begin to be heated to 89 ℃～91 ℃; Heat and stop heating after 2～2.5 hours; Staticly settle, after the reactant static layering in the question response still, get reaction precipitation thing and reaction supernatant;
(4), negate answers supernatant, in the reaction supernatant, slowly adds hydrochloric acid soln, mixes, and reduces to 2 until the pH value of supernatant, staticly settles 8～12 hours, gets the oven dry of supernatant throw out, the potassium fulvate finished product;
(5), negate answers throw out, places settling tank, presses the reaction precipitation thing: the raw material weight proportioning of humic acids=1: 0.5～0.8, above-mentioned raw materials is mixed, left standstill 2～3 hours, compound is carried out spray granulating, must contain the fertilizer of potassium and humic acids.
Described alkaline substance is sodium hydroxide or Pottasium Hydroxide or Potassium peroxide 85 or hydrated barta.
Described biomechanical gray comprises the ash that produces behind cigarette ash in the flue gas that is produced behind the coal combustion, the burning plants.Aforesaid method has been realized the object of the invention.
Advantage of the present invention is a regenerated resource development and utilization, and is free from environmental pollution, reduced effluent charge usefulness significantly, and it is simple and practical also to have method, and extraction cost is low, only is 70% of traditional method cost.Do not have the wasting of resources in the leaching process of the present invention, production process does not produce solid waste, and reactant all has utilization, increases resource utilization.
