Abstract
The invention discloses a liquid humic acid water-soluble fertilizer production method. The production method mainly includes the following steps that decomposed coal is crushed and pulped and reacts with alkali liquor to obtain a solution, the obtained solution is separated in a centrifugal mode, after triple-effect concentration is conducted on the liquid humic acid, urea, monopotassium phosphate and nitrate of potash are added to the concentrated liquid to be stirred and filtered and then to be put into another reaction kettle, potassium hydroxide is added in the reaction kettle to conduct a reaction, and finally liquid humic acid water-soluble fertilizer is obtained. The liquid humic acid water-soluble fertilizer production method has the advantages that continuous reaction, centrifugal separation and other technologies are adopted to achieve continuous, self-control and stable production; the utilization rate of raw materials and heat energy is high; the liquid humic acid water-soluble fertilizer can be absorbed by plants easily.
Description
Technical field
The present invention relates to the production method of liquid humic acid water-soluble fertilizer, belong to humic acids preparation field.
Background technology
Water-soluble fertilizer (WaterSolubleFertilizer, be called for short WSF) refers to the multielement compound fertilizer that can be dissolved in water completely, have instant, specific absorption is high, instant effect, without residue, use to facilitate etc. and show advantage.Water-soluble humic acid fertilizer refers to the humic acids of ratio needed for applicable plant-growth, adds the liquid or solid water-soluble fertilizer that the trace elements such as proper N, phosphorus, potassium macroelement or zinc, boron, iron, molybdenum, manganese, copper are made.Water-soluble humic acid fertilizer, through water dissolution or dilution, dips in the purposes such as root for fertigation, leaf dressing, soilless culture, seed soaking.
At present, domesticly substantially continue to use interval extracting small-scale production, unstable product quality, production process energy consumption is comparatively large, and the heat of generation cannot reuse, and energy consumption is high, seriously polluted, causes manufacturing enterprise's deficiency in economic performance.
Summary of the invention
In order to solve the problem described in background technology, the invention provides the production method of liquid humic acid water-soluble fertilizer.
The present invention is achieved by the following technical solutions: a kind of production method of liquid humic acid water-soluble fertilizer, concrete: to comprise the following steps:

(2) coal water slurry and alkaline reaction, the following parameter of concrete control: be that 20% potassium hydroxide solution adds in reactor by the coal water slurry made and percent mass hundred concentration, the additional proportion of the two is according to weathered coal and potassium hydroxide weight ratio 1:0.08-0.09, temperature controls at 80-85 degree, stirring reaction 40-45 minute;
(3) separation of humic acid solution is with concentrated: the solution that step (3) is obtained by reacting is after centrifugation, and the humic acids of liquid, after triple effect is concentrated, obtains the humic acids concentrated solution that mass percentage concentration is 25-30%;
(4) urea, potassium primary phosphate, the anti-filtration of saltpetre stirring is added in the humic acids concentrated solution that step (3) obtains.
(5) liquid that step (4) obtains enters another reactor, adds potassium hydroxide reaction in a kettle., obtains liquid humic acid water-soluble fertile.
Further, in described step (4), urea is incorporated as the 13.3-14.1% of liquid gross weight, the add-on of potassium primary phosphate is the 7.4-7.8% of liquid gross weight, the add-on of nitric acid is the 9.3-9.9% of gained liquid gross weight.Temperature controls at 65-70 degree, stirring reaction 45-60min.
Further, in described step (5), the concentration of potassium hydroxide is 3mol/L, add-on 220ml/L step (4) the gained liquid of potassium hydroxide solution.
The invention has the beneficial effects as follows:: 1, adopt successive reaction, centrifugation, etc. technology realize continuously, automatic control, stably manufactured; 2, raw material, heat utilization rate are high; 3, product is the humic acid water-soluble fertilizer of liquid, is conducive to plant absorption.
embodiment:
The technique of carrying out humic acids production below in conjunction with the feed coal choosing Shanxi Lingshi County is described as follows:
Choosing of feed coal: feed coal moisture≤20%, organic carbon: 50-70%, total humic acid: 40-65%, be less than particle >=90% of 80 order granularities, adopt volumetry to detect mining area containing the humic acids content in humic acid material ore deposit, weighting method measures Raw Ore moisture, ash content and humic acids graded index xanthohumic acid, ulmic acid, Ulmic acids content.
Feed coal is delivered to rubber conveyer through oscillating feeder, vertical-spindle hammer crusher is delivered to after iron removal by magnetic separation, raw material after coarse crushing delivers to surge bunker through rubber conveyer again, deliver to ball mill through belt weigher, screw feeder, added water in right amount by metering water pump simultaneously and carry out wet-milling, deliver to colour strainer by after coal or peat grinding, filter the coal paste storage tank of laggard belt stirrer, be prepared into coal water slurry, in coal water slurry, the granular size of coal controls at 80-100 order, and mass percentage concentration is 20-23%.
Be that 20% potassium hydroxide solution adds in reactor by the coal water slurry made and percent mass hundred concentration, the additional proportion of the two is according to weathered coal and potassium hydroxide weight ratio 1:0.08-0.09, and temperature controls at 80-85 degree, stirring reaction 40-45 minute.
