Abstract
A kind of carbon ammonia granule compound mixing fertilizer can be widely used in various farm crop, is characterized in adopting bicarbonate of ammonia as nitrogenous source, and one of phosphogypsum or rhombspar and sepiolite mixture are made additive, and its raw material sources are abundant, and are cheap.The fertile various nutrients of the compound of forming are stable, but longer-term deposit, nutrient content meets national standard.This compound is fertile to adopt no drying machinery extruder grain, and Production Flow Chart is short, and facility investment is few, in being suitable for, small fertilizer plant and township and village enterprises's use.
Description
The present invention relates to a kind of fertilizer and production method thereof, is a kind of production method of composite fertilizer specifically.
Composite fertilizer's applying on agricultural in recent years, effect of increasing production is very remarkable, and agriculture production needs more and more urgent to composite fertilizer.The existing composite fertilizer strain overwhelming majority is a urea-Pu calcium system, part ammonium chloride-Pu calcium system and a spot of urea (or ammonium chloride)-phosphorus ammonium system etc., and the required nitrogenous source of these several strains is very in short supply at present.But the carbon ammonium that small nitrogenous fertilizer plant is produced, owing to many reasons, its selling market is extremely unstable, and the fertilizing method of singly executing the carbon ammonium more and more can not adapt to the development of agriculture production.
The research of carbon ammonium series compound fertilizer is not seen in report abroad as yet, domestic carry out the fertile research of carbon ammonium compound so far for to existing report related to the present invention have following two kinds: pulverize (1) general calcium oven dry back, add carbon ammonium, Repone K again, mix back packing (or extruder grain).There are a lot of defectives in this way, at first general calcium has been sloughed partial crystallization water in drying course, make the part water-soluble phosphorus be converted into the molten phosphorus of Chinese holly simultaneously, when evidence reaches 200 ℃ when temperature, water-soluble phosphorus can only keep 50%, and when general calcium mixed with the carbon ammonium, its free acid and monocalcium phosphate reacted in addition, make water miscible monocalcium phosphate change into secondary calcium phosphate, reduced water-soluble rate.(2) pulverize behind the calcined dolomite, add the phosphorus ammonium, mix, add carbon ammonium, Repone K again, mix back packing (or passing through extruder grain).This method also has a lot of defectives, at first cost is too high, as rhombspar through exploitation, calcining, pulverizing, transportation cost need 170 surplus yuan, main component is MgO and CaO behind the dolomite calcination on the other hand, the ammonium magnesium phosphate that itself and the reaction of phosphorus ammonium generate has very strong water-absorbent, but it is insoluble in water, and phosphorus all is the molten phosphorus of Chinese holly, the CaHPO of generation
4Also be the molten phosphorus of Chinese holly, water-soluble phosphorus reduces greatly in the phosphorus ammonium thereby make.Test shows: the water-soluble phosphorus 87.3% in the phosphorus ammonium adds the molten phosphorus of compound rich water that ground dolomite produces only 15.06%.For above-mentioned reasons, be that the compound fertilizer that nitrogenous source produces all can not be up to state standards with the carbon ammonium at present.
The objective of the invention is to overcome the defective of aforesaid method, a kind of method of new production carbon ammonium compound fertilizer is provided.
Below narrate main contents of the present invention:
Carbon ammonia granule compound mixing fertilizer of the present invention is made up of bicarbonate of ammonia, phosphorus ammonium, potash fertilizer (Repone K or vitriolate of tartar) and additive.A large amount of evidences, the selection of additive is the key of producing carbon ammonium compound fertilizer, it should have the intensive water sorption, to improve the stability of carbon ammonium, stronger plasticity and viscosifying power are arranged again so that the production of compound fertilizer granulation, and less to water-soluble phosphorus content influence in the product, raw material sources are extensive, cheap.Through optimizing in many ways, screening, the present invention proposes the mixture of phosphogypsum or rhombspar and sepiolite and makes additive.This carbon ammonia granule compound mixing fertilizer, its major ingredient scope is: volatile salt hydrogen 40-60%, phosphorus ammonium 10-20%, potash fertilizer 10-20%, additive is the add-on difference according to the kind difference, if phosphogypsum then add-on be 8-12%, if rhombspar and sepiolite mixture, then the rhombspar consumption is the 1/3-1/4 of phosphorus ammonium consumption, and the sepiolite consumption can account for the 3-30% of compound fertilizer.
Narrate the manufacturing process of carbon ammonium compound fertilizer below.
1, gets the raw materials ready
The phosphorus ammonium: phosphorus ammonium source is different, and its water content and anti-caking differ greatly, if water content (MAP＜2% that is above standard in the phosphorus ammonium, DAP＜2.5%) must dry and make moisture content up to standard, and hard foreign material such as pulverizing, (1mm) impurity elimination, the especially irony of sieving, store for future use then.
Additive: the general water content of phosphogypsum (or rhombspar and sepiolite mixture) is all higher, and average moisture content reaches 30%, it must be dried, and sloughs crystal water, and impurity elimination is pulverized, and crosses the 1mm sieve, cools off standby.
Potash fertilizer: potash fertilizer is avoided chlorine different selective chlorination potassium or vitriolate of tartar according to crop, preferably selects powder-like product, if the macrobead product must be pulverized it, standby then, the general water content of potash fertilizer need not dried all less than 1%.
The carbon ammonium: carbon ammonium water content answers＜3.5%.
