Description

Technical Field

[0001] The utility model relates to the technical field of ammonia water production, in particular to an ammonia water rapid circulation mixing device. Background Art

[0002] Ammonia water is one of the important products of the basic chemical industry and an important chemical raw material. When ammonia water is produced in industrial production, ammonia and water are usually introduced into the reaction system, and ammonia is dissolved in water to form ammonia water. In the specific production process, ammonia is introduced into the reaction system first and then water. When shutting down, ammonia is stopped first and then water. Therefore, in the early and late stages of production, the flow of ammonia and water is relatively unstable, resulting in uneven concentrations of ammonia water produced in the early stage and the late stage. At present, the outlet and reflux port of the circulating mixing device are both at the bottom of the reaction system. When circulating, the ammonia water at the bottom is pumped back to the bottom, causing the ammonia water at the top to not flow and the mixing to be uneven. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0013] like Figure 1 As shown, the utility model ammonia rapid circulation mixing device comprises an ammonia intermediate tank 1 and an ammonia intermediate pump 2, an annular reflux pipe 3 is arranged in the ammonia intermediate tank 1, a nozzle 4 for spraying toward the tank is arranged on the annular reflux pipe 3, an inlet end of the ammonia intermediate pump 2 is connected to a water inlet pipe 5, the water inlet pipe 5 is connected to the ammonia intermediate tank 1, an outlet end of the ammonia intermediate pump 2 is connected to an ammonia external delivery pipeline 10, a reflux pipe 8 is connected to the ammonia external delivery pipeline 10, the reflux pipe 8 is connected to the annular reflux pipe 3 in the ammonia intermediate tank 1, and the annular reflux pipe 3 is located above the connection between the water inlet pipe 5 and the ammonia intermediate tank 1.

[0014] When the utility model is implemented, the annular reflux pipe 3 is horizontally fixed on the inner wall of the ammonia water intermediate tank 1, and a main pipe 6 and a branch pipe 7 are arranged in the middle of the annular reflux pipe 3.
