Description

Technical Field

[0001] The invention relates to a reaction kettle, in particular to a sulfamic acid reaction kettle provided with a quantitative feeding structure, belonging to the technical field of sulfamic acid production equipment. Background Art

[0002] Sulfamic acid is an inorganic solid acid formed by replacing the hydroxyl group of sulfuric acid with an amino group. Sulfamic acid can be used to synthesize herbicides, fire retardants, sweeteners, preservatives, metal cleaning agents, etc. It is a common chemical raw material. During its preparation, a reactor is used for preparation. The fuming sulfuric acid method is a more commonly used preparation method. During the preparation, the raw materials are urea and fuming sulfuric acid. Under the condition of 40-70℃, urea and fuming sulfuric acid undergo sulfonation reaction to generate crude sulfamic acid. After the reaction is completed, the refined product is obtained through filtration, water treatment crystallization and other steps. During the reaction, a reactor is required to react. During the reaction, the accurate amount of urea granule feed is required. The properties and sufficiency of urea in contact with fuming sulfuric acid are important measures to improve the quality and yield of aminosulfonic acid. In addition, since the sealing environment needs to be strictly controlled to avoid leakage during the production of aminosulfonic acid, some current quantitative feeding structures may easily cause the internal environment of the reactor to be connected with the external environment during the quantitative feeding process, resulting in damage to the sealing environment. Moreover, during feeding, since urea granules are contained, which are corrosive to a certain extent, the feeding structure is prone to wear and tear after long-term use, which is inconvenient to maintain. Moreover, during feeding, urea granules or detached powder are easily attached to the quantitative feeding structure, resulting in inaccurate quantitative feeding. Summary of the Invention

Through the feed hopper, the quantitative urea granules in the quantitative assembly are discharged into the connecting pipe and enter the interior of the reactor body through the guide pipe. When feeding, the electric ball valve is opened, and the reactor body is sealed from the outside by rotating the ball, thereby preventing the reactor body from being connected to the outside through the feed assembly and the quantitative assembly.
