Description

Be applied to compound fertilizer's urea sulfate reaction unit
Technical Field
The embodiment of the utility model relates to the field of fertilizers, in particular to a urea sulfate reaction device applied to compound fertilizers.
Background
The current production process of high-concentration compound fertilizer in China mainly comprises the following steps: the method comprises four main production processes of a granulating method, a high-tower granulating and ammonifying granulating method of a melt (comprising a dilute sulfuric acid ammonifying granulating process and a concentrated phosphoric acid ammonifying granulating process), and an ammonifying granulating process of mixed acid full slurry of potassium bisulfate and phosphoric acid. The granulating method is a traditional high-concentration compound fertilizer production process, and various production raw materials are mixed and then are heated by steam in a rotary drum granulator and supplemented with proper water for kneading and granulating. All raw materials in the process of the granule method are solid materials. The high tower granulation process of the melt is to mix nitrogen, phosphorus, potassium and auxiliary materials in three stages, form a co-melt under the condition of heating by an external heat source, spray the co-melt from the top of the granulation tower, form particles by utilizing surface tension and contact with cold air in the falling process to realize the cooling process. All materials in the melt granulation process are solid materials. The ammonification granulation is of various types at present, such as traditional dilute sulfuric acid ammonification granulation, concentrated phosphoric acid ammonification granulation, dilute phosphoric acid ammonification granulation and the like, and is characterized in that acidic liquid and ammonia are subjected to neutralization reaction in a tubular reactor to form high-temperature slurry with certain pressure, and the high-temperature slurry is sprayed on a material bed of a rotary drum granulator through a spray head on the tubular reactor to be mixed with returned materials for hot melt granulation. Although part of raw materials are liquid and gas, a large amount of raw materials are solid materials (phosphorus in the concentrated phosphoric acid ammonification granulation is a full liquid material), more or less secondary processing exists, and the raw material cost and the compound fertilizer production cost are increased. The mixed acid full slurry pelletization is mainly applied to a device for producing sulfur-based compound fertilizer by dechlorination and conversion of potassium chloride, phosphorus and potassium raw materials are mixed liquid and gas ammonia to form high-temperature slurry with certain pressure by neutralization reaction in a tubular reactor, and the high-temperature slurry is sprayed on a material bed of a rotary drum pelletizer through a spray head on the tubular reactor to be mixed with return materials for hot melt pelletization.
With the continuous advancement of technology, few enterprises have begun to use urea sulfate ammoniation slurry spraying. The urea sulfate ammoniation slurry spraying method is an advanced granulation method which integrates the advantages of the various granulation methods, and is suitable for the compound fertilizer which can be produced by the granulation method, the compound fertilizer which can not be or is difficult to produce by the granulation method, and elemental fertilizers such as ammonium sulfate granulation, potassium fertilizer granulation, potassium sulfate granule and the like. However, in practical production, the urea sulfate reaction device used by the traditional urea sulfate process equipment has the advantages of complex structure, troublesome operation and short service period. When participating in granulation, the urea sulfate reaction device is usually required to be placed in a granulator, urea sulfate is sprayed to a material bed of the granulator, and a subsequent granulation link is performed. However, the whole process not only needs to discharge the granulated tail gas, but also needs to discharge the tail gas produced by urea sulfate, and the purification treatment is carried out, so that the production cost of the compound fertilizer is increased.
