Abstract
The invention relates to a method for producing a chlorine-based guniting compound fertilizer. The method comprises the following steps: mixing potassium chloride, ammonium chloride and water in a certain ratio, grinding in a ball mill to obtain slurry as a product A, mixing ammonium chloride with concentrated sulfuric acid in a certain ratio, performing low-temperature transformation, neutralizing the mixture together with phosphoric acid and liquid ammonia in a tubular reactor in a certain ratio so as to obtain slurry as a product C, feeding the product A and the product C into a slurry storage tank by using a metering pump in a certain ratio, uniformly mixing, feeding into a granulating barrel for guniting granulation by using the metering pump, and cooling and screening the product, thereby obtaining the chlorine-based guniting compound fertilizer. The chlorine-based guniting compound fertilizer has the advantages of small amount of byproduct hydrochloric acid, low production cost and relatively flexible formula.
Description
Technical field
The present invention relates to the production method of a kind of chloro whitewashing composite fertilizer, belong to technical field of fertilizer production.
Background technology
Current domestic whitewashing composite fertilizer is all sulfenyl product, and the sal enixum that the potassium element in sulfenyl product is mainly produced by low temperature conversion method is main, when producing sal enixum, by product is hydrochloric acid, current domestic hydrochloric acid market saturation, hydrochloric acid faces process trouble and waits series of problems, and the producer even had pays out of one's own pocket and sells hydrochloric acid, causes burden to society and enterprise.
On the other hand, because potassium content in sal enixum and the potassium content in Repone K are all than much lower, so potassium content does not increase in whitewashing composite fertilizer, constrain the handiness of product.
The third aspect, traditional sulfenyl whitewashing composite fertilizer cost is far above the chlorine base fertilizer on market, and product competitiveness is not strong.
Fourth aspect, sulfenyl is in the market mainly used in cash crop, and chloro is mainly used in field crop, domestic with land for growing field crops
Crop is main, and cash crop are auxiliary, therefore is not so good as the large of chlorine base fertilizer to the fertile demand of sulfenyl.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of chloro whitewashing composite fertilizer producing process, by-product hydrochloric acid is few, and production cost is low, and formula is more flexible, to meet the need of market better.
In order to solve the problems of the technologies described above, the present invention by the following technical solutions:
A kind of chloro whitewashing composite fertilizer producing process, is characterized in that carrying out according to following steps:
(1), Repone K, ammonium chloride are mixed according to the ratio of mass ratio 0.06 ~ 2.5:0 ~ 2.5:1 with water after, become slip through ball mill grinding, obtain component A;
And mixed with the ratio of the vitriol oil according to mass ratio 0.7 ~ 1.5:1 by Repone K, and after transforming through 110 ~ 220 DEG C, obtain B component; Then B component and phosphoric acid are neutralized by tubular reactor and liquefied ammonia according to the ratio of volume ratio 1:0.5 ~ 6, obtain component C;
(2), squeeze in slip storage tank by volume pump according to the ratio of volume ratio 1:2 ~ 9 by component A and component C, mixing, then squeezes into spray granulating in pelletizing drum by volume pump, after cooling, screening, obtains chloro whitewashing composite fertilizer.
The degree of neutralization neutralized by tubular reactor and liquefied ammonia is controlled 1.0 ~ 1.5.
Positively effect of the present invention is:
1), the present invention produce by-product hydrochloric acid less, can alleviate the saturated of current hydrochloric acid market and store difficulty etc. problem.
2), the present invention transforms on original sulfenyl spray granulating basis, and less investment, not only can produce sulfenyl but also can produce chloro after transformation, and formula is more flexible, meets the need of market.
3), product of the present invention compared with traditional sulfenyl fertilizer, production cost is fertile far below traditional sulfenyl.
4), the blank of domestic whitewashing chlorine base fertilizer has been filled up.
5), product of the present invention mainly based on Repone K, suitably add sal enixum and regulate chloride ion content in product, product is more flexible, can produce the multiple products such as low chlorine, middle chlorine, high chlorine.
