The method is simple and reasonable in process flow, stable in quality, and low in energy consumption and cost, and comprises the following steps: respectively conveying a humic acid-containing mineral source raw material and a solid activating agent into a crusher and a mixing machine sequentially through a solid conveying device, then conveying the crushed and mixed humic acid-containing mineral source raw material and solid activating agent to a pelletization equipment inlet through the conveying device, introducing steam and hot water into pelletization equipment simultaneously, performing cohesive granulation on humate powder generated by reaction of the humic acid-containing mineral source raw material and the solid activating agent, and drying and cooling to obtain a humate solid product; or crushing the humic acid-containing mineral source raw material by the crusher, conveying the crushed humic acid-containing mineral source raw material to the pelletization equipment through the conveying device, simultaneously, conveying a liquid activating agent to the pelletization equipment through a pipeline, simultaneously, introducing steam and hot water into the pelletization equipment, performing cohesive granulation on humate powder generated by reaction of the humic acid-containing mineral source raw material and the liquid activating agent, and drying and cooling to obtain the humate solid product.
Description
Technical field
The invention belongs to the prilling process of humate, particularly relate to a kind of prilling process utilizing tablets press to prepare spherical solid particles humate.
Background technology
The traditional processing technology preparing humate with mineral sources humic acid materials such as brown coal, weathered coal, peat takes wet processing flow process: by raw material pulverizing, add the water of activator and several times raw material volume, reacting by heating, then solid-liquid separation, liquid obtains humate product through evaporation drying.The advantage of the method is that the purity of product is high, but there is small scale, the problem such as energy consumption is large, cost is high, residue contamination environment.
Summary of the invention
The present invention is directed to conventional wet technique Problems existing; using crusher, mixing machine, rotary drum granulator and disc-type granulating machine, drying machine, cooler, sieve apparatus as major equipment, humic acid material and activator complete fragmentation, powder process, mixing, priming reaction, granulation, dry integrated dry method technological process simultaneously in said system.Spherical solid particles humate after sieve apparatus is humate product through metering, packaging.
Present method thoroughly avoids the reaction that first adds water existed in wet production, rear evaporation drying removes the problem of residue contamination environment after the highly energy-consuming problem of moisture and solid-liquid separation, to avoid with coal pulverizer be the first drying and dehydrating of dry process Raw of core simultaneously, powder process, the granulation that adds water again after activation drawback, humic acids activation, granulation, drying are once completed, spheroidal particle product is more user-friendly, technical process is succinctly reasonable, and steady quality, energy consumption is low, cost is low.
Technical scheme of the present invention is as follows: enter crusher, mixing machine successively containing humic acid minerals source raw material and solid activating agent respectively through solids delivery device, then granulating equipment entrance is sent into through e Foerderanlage, granulating equipment passes into steam and hot water simultaneously, the humate powder generated containing humic acid minerals source raw material and solid activating agent reaction is glutinous is polymerized to grain, and drying, cooling are humate solid phase prod; Or be delivered to granulating equipment by after crusher in crushing through e Foerderanlage containing humic acid minerals source raw material, simultaneously liquid activating agent through Cemented filling to granulating equipment, granulating equipment passes into steam and hot water simultaneously, the humate powder generated containing humic acid minerals source raw material and liquid activating agent reaction is glutinous is polymerized to grain, and drying, cooling are humate solid phase prod.
Optionally, described containing humic acid minerals source raw material to be humic acids content be not less than 30% brown coal, weathered coal or peat any one or multiple combination.
Optionally, the particle fineness after crusher in crushing crosses 20 mesh sieves, and screenings is less than 10%.
Optionally, described activator comprises strong basicity raw material or strong base weak acid raw material.
Optionally, described strong basicity raw material is sodium hydroxide or potassium hydroxide; Described strong base weak acid raw material is sodium carbonate or salt of wormwood.
Optionally, described activator is made up of one or both compounds above.
Optionally, described granulating equipment is rotary drum granulator or disc-type granulating machine, or their combination.
Optionally, granulating equipment passes into steam and hot water, and the temperature of steam is less than 180 DEG C, and absolute pressure is lower than 1.0Mpa, and the temperature of hot water is less than 100 DEG C.
Humic acid minerals source raw material described in technique scheme is any one in weathered coal, brown coal or peat or multiple combination, and water content is 10%-60%, humic acids content (butt) >=30%.
Mixing machine is more even by what mix containing the powder after the raw material crushing of humic acid minerals source and solid activating agent, and quality product is better, no matter whether arranges mixed processes, can not produce substantial effect to granulating working procedure.
Humate spherical solid particles prepared by method provided by the invention, its main component is: containing water-soluble humic acids more than 15%, and moisture content 10 ﹪-30%, particle diameter is at 1.00mm-5.6mm.
Method provided by the invention is compared with published method, and tool has the following advantages:
1. scale is large
The single covering device scale in conventional wet technique that avoids is difficult to reach the problem of 10,000 tons, and according to the technique of present method, the list cover scale of humate can reach 200,000 tons.
2. energy consumption is low
Avoid the energy consumption of first extracting in water and then drying and dehydrating in humate conventional wet technique, greatly reduce cost.
To avoid with coal pulverizer be the first drying and dehydrating of humate dry process Raw of core, powder process, the granulating and drying that adds water again after activation drawback.
Granulation process in present method needs additional steam and hot water, be used for improving the temperature of material and adjusting water content, even if therefore also do not need drying and dehydrating to the humic acid minerals source raw material of High water cut, humic acids activation, granulation, drying are once completed, technical process is reasonable, and energy consumption is low, cost is low.
3. spherical solid particles shape product
Due to solid content only 6%-18% in humate conventional wet technique, adopt spraying or roller drying, product is Powdered, sheet, not only airborne dust in using, and agricultural machinery can not be used to apply fertilizer, and affects product promoting the use of in agricultural.
Present method not only makes the activation of humate, granulation, drying once complete, and because the product size of capacity is large, energy consumption is low, cost is low, product is attractive in appearance, be suitable for farmland soil and execute popularization, spheroidal particle product applies fertilizer agriculturally can using existing fertilizer machinery, not airborne dust in using, more user-friendly, compensate for the limitation that conventional wet handicraft product cost height is only suitable for dropper, foliage-spray, wide market.
