Description

Technical Field

[0001] The utility model relates to the technical field of compound fertilizer production, in particular to a tubular reactor for ammoniation of compound fertilizer. Background Art

[0002] Ammoniation granulation compound fertilizer adopts ammoniation and secondary dechlorination granulation production process. The principle is to add potassium chloride and sulfuric acid into the reaction tank, heat them and react under certain conditions. The escaped HCL gas can be absorbed by water to produce hydrochloric acid of a certain concentration. The generated potassium hydrogen sulfate is mixed with dilute phosphoric acid to form a mixed acid. The mixed acid is reacted with synthetic ammonia in a tubular reactor in proportion to generate compound fertilizer slurry, which is directly sprayed into the rotary drum granulator to generate sulfur-based compound fertilizer with a certain proportion of nitrogen, phosphorus and potassium.

[0003] For example, a tubular reactor of an ammonified compound fertilizer disclosed in Publication No. CN217189579U is provided with a sealing cylinder, an end cover, a drawstring, a scraping ring and other structures. When the tube body needs to be cleaned, a cleaning agent is first added to the inside of the tube body, and then the end cover is opened, and the drawstring is pulled through the end cover. The drawstring will act on the scraping ring to move along the inner wall of the tube body, thereby scraping off the dirt, which is more convenient. However, some raw materials of the ammonified compound fertilizer are corrosive, and the drawstring arranged in the reaction tube may be corroded and then broken after long-term use, making the cleaning structure unusable. For this reason, a tubular reactor of an ammonified compound fertilizer is proposed to be improved. Utility Model Content
