Abstract
The invention discloses a method for producing high-sulfur ammonium sulfate. The method is characterized by increasing the total amount of sulfur contained in an ammonium sulfate product by adding sulfur or magnesium sulfate of 8%-15% in percentage by weight in the production process of a general ammonium sulfate product. The high-sulfur ammonium sulfate is suitable for a region of severe sulfur shortage to supplement the need of crops, is low in cost, and is suitable for a region which has no need of supplementing a large amount of nitrogen and needs more sulfur, thereby preventing the conditions of high cost and nitrogen waste which are caused by supplementing sulfur by using general ammonium sulfate products.
Description
Technical field
The present invention relates to ammonium sulfate, specifically relate to a kind of production method of ammonium sulfate.
Background technology
Ammonium sulfate, except nitrogenous, also containing element sulphur, is a kind of important sulfur fertilizer.In the area of lack of soil sulfur, use sulphur ammonium can the important sources of soil sulphur as a supplement.
The theoretical nitrogen content of sulphur ammonium is 21.21%, and sulphur content is 24.24%, in its production process, be inevitably mixed into some impurity, may reduce the available nutrient content of sulphur ammonium.In the area of some serious as lack of sulfur, common sulphur ammonium fertilising consumption, the sulphur content of sulphur ammonium is not enough to needed for supplementary crop, if increase the consumption of sulphur ammonium, although improve the total amount of element sulphur, causes the rising of cost and the waste of nitrogen element.
Summary of the invention
The object of the present invention is to provide a kind of production method of high elemental sulphur ammonium, the ammonium sulfate products of the high element sulphur produced is suitable for not needing supplementary a large amount of nitrogen element, but need the area of more element sulphur, avoid that to use general ammonium sulfate products to supplement the cost that element sulphur causes high, the situation of nitrogen element waste.
The technical scheme realizing the object of the invention is: a kind of production method of high elemental sulphur ammonium, be characterized in utilizing the sulphur or the magnesium sulfate that add mass percentage 8-15% in common ammonium sulfate products production process, the element sulphur total amount in ammonium sulfate products is improved.
Aforesaid method may be used for producing crystal sulphur ammonium, also can be used for producing granular ammonium sulfate products.
The advantage of fertilizer of the present invention: high elemental sulphur ammonium of the present invention is applicable to the area of serious a lack of sulfur, and needed for supplementary crop, cost is low; Be suitable for not needing supplementary a large amount of nitrogen element, but need the area of more element sulphur, avoid that to use general ammonium sulfate products to supplement the cost that element sulphur causes high, the situation of nitrogen element waste.
Embodiment
Further illustrate the present invention below by way of specific embodiment, but be not used for limiting the scope of the invention.
Embodiment 1
In the production process of sulphur ammonium, with the addition of the magnesium sulfate of 10% in sulphur ammonium, in magnesium sulfate, the content of element sulphur is 25.35%, and higher than the sulphur content 23.35% of sulphur ammonium, after adding magnesium sulfate, it is 23.55% that the sulphur content of product raises.
Embodiment 2
In the production process of sulphur ammonium, in sulphur ammonium, with the addition of the sulphur of 9%, the element sulphur total amount in ammonium sulfate products is improved.
Claims (2)
1. a production method for high elemental sulphur ammonium, is characterized in that in common ammonium sulfate products production process, add mass percentage 8-15% sulphur or magnesium sulfate, and the element sulphur total amount in ammonium sulfate products is improved.
2. the production method of high elemental sulphur ammonium according to claim 1, is characterized in that described common ammonium sulfate products produces crystal ammonium sulfate products, or produces granular ammonium sulfate products.
