Description

Technical Field

[0001] This utility model belongs to the field of chemical machinery technology, and in particular relates to a nozzle device for a tubular reactor of ammonium dihydrogen phosphate. Background Technology

[0002] The core equipment for producing ammonium dihydrogen phosphate using existing methods is a tubular reaction nozzle device. Phosphoric acid reacts with gaseous ammonia to produce a slurry, which is then sprayed out through the nozzle. After the slurry is cooled and the moisture evaporated in a cooling tower, it can be collected as the finished product. If the slurry can rotate within the device and the spray velocity is increased, a better finished product of ammonium dihydrogen phosphate can be obtained. Therefore, a tubular reactor nozzle device that can achieve the above functions is needed. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides a tube-type reactor nozzle device for ammonium dihydrogen phosphate.

[0004] This utility model is achieved through the following technical solution.

[0005] This utility model provides a tubular reactor nozzle device for ammonium dihydrogen phosphate, comprising a mixed acid reactor and a nozzle. The mixed acid reactor has openings at both ends, and a first flange is provided at each of the openings. The nozzle has an opening at one end and a nozzle at the other end, and a second flange is provided at one end of the nozzle opening. The mixed acid reactor and the nozzle are connected and fastened together through the first flange and the second flange.

[0006] Preferably, the mixed acid reactor is provided with a first ammonia inlet and a second ammonia inlet, and a third flange is provided at the inlet ends of the first ammonia inlet and the second ammonia inlet.

[0007] Preferably, the first ammonia inlet and the second ammonia inlet are arranged perpendicular to the axis of the mixed acid reactor, and the first ammonia inlet and the second ammonia inlet are arranged symmetrically.

[0008] Preferably, the inner wall of the nozzle is provided with swirl blades.

[0009] Preferably, the swirl blade is a square-shaped thin sheet.

[0010] Preferably, the swirl blades are arranged in a spiral pattern on the inner wall of the nozzle.

[0011] Preferably, the nozzle is connected to the nozzle outlet via a pressurization pipe.

[0012] Preferably, the booster tube is conical or regular polyhedral in shape.

[0013] The beneficial effects of this utility model are as follows: Using the technical solution of this utility model, phosphoric acid enters from the left side of the mixed acid reactor and reacts fully with the ammonia gas from the upper and lower ammonia inlets to obtain a slurry. After the slurry enters the nozzle, it is guided by the swirl vanes, causing the material to rotate in the pipe. Then, the pressurization effect of the pressurizing cone increases the spray velocity. Finally, the material is sprayed out in an atomized state. The atomized slurry has finer particles and evaporates water faster than the ordinary directly sprayed slurry. Compared with ordinary nozzles, it can produce better finished ammonium dihydrogen phosphate. Attached Figure Description

Detailed Implementation

[0015] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0016] Example 1: like Figure 1-2 As shown, a tubular reactor nozzle device for ammonium dihydrogen phosphate includes a mixed acid reactor 1 and a nozzle 2. The mixed acid reactor 1 has openings at both ends. The opening at the end of the mixed acid reactor 1 away from the nozzle 2 is the raw material inlet. A first flange 11 is provided at the openings at both ends of the mixed acid reactor 1. The nozzle 2 has an opening at one end and a nozzle 24 at the other end. A second flange 21 is provided at the opening end of the nozzle 2. The mixed acid reactor 1 and the nozzle 2 are connected and fastened through the first flange 11 and the second flange 21.

[0017] The mixed acid reactor 1 is provided with a first ammonia inlet 12 and a second ammonia inlet 13. A third flange 14 is provided at the inlet ends of the first ammonia inlet 12 and the second ammonia inlet 13. The first ammonia inlet 12 and the second ammonia inlet 13 can be connected to the ammonia supply equipment through the third flange 14. The mixed acid reactor 1 and the first ammonia inlet 12 and the second ammonia inlet 13 form a cross-shaped four-way structure. By setting two sets of ammonia inlets (12) and (13), a more thorough and complete reaction can be ensured.

[0018] The first ammonia inlet 12 and the second ammonia inlet 13 are arranged perpendicular to the axis of the mixed acid reactor 1, and the first ammonia inlet 12 and the second ammonia inlet 13 are arranged symmetrically.
