Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-5 , this utility model provides a technical solution:

[0026] A phosphorus pentachloride synthesis reactor comprises a reactor body 1, the reactor body 1 comprising an outer sleeve 2 and an inner sleeve 3. A flow guide baffle 4 is bolted to the bottom of the inner portion of the outer sleeve 2, and the inner sleeve 3 is bolted to the top of the flow guide baffle 4.

The top of the chlorine gas inlet 6 extends into the interior of the inner sleeve 3. A gas distributor 7 is bolted to the bottom of the inner sleeve 3. A distribution assembly 8 and a connecting assembly 9 are rotatably connected and bolted to the top of the gas distributor 7, respectively.

[0027] The distribution assembly 8 includes a delivery pipe 81, which is rotatably connected to the top of the gas distributor 7, and the top and surface of the delivery pipe 81 are both sleeved with a connecting plate 82. The surface of the connecting plate 82 is annular and fixedly connected to a number of diversion pipes 83. The top of the diversion pipe 83 is fixedly connected to a number of nozzles 84. The surface of the delivery pipe 81 is sleeved with a support ring 85. The surface of the support ring 85 is annular and bolted to a support rod 86, and the support rod 86 is bolted to the side close to the diversion pipe 83.

[0028] In this embodiment, by providing a distribution component 8, a portion of the chlorine gas entering the chlorine inlet 6 will be evenly distributed in the inner sleeve 3 through the gas distributor 7, while the other portion of the chlorine gas will enter the delivery pipe 81 and be distributed to multiple branch pipes 83 through the connecting plate 82, and then be sprayed into the inner sleeve 3 through the nozzle 84. This can make the chlorine gas evenly distributed at different radial positions in the inner sleeve 3, thereby improving the uniformity and stability of the chlorine distribution. By providing a connecting component 9, the distribution component 8 can be rotated in the inner sleeve 3 through the connecting component 9, so that the chlorine gas sprayed through the distribution component 8 can be evenly distributed at different radial positions in the inner sleeve 3, thereby improving the uniformity and stability of the chlorine distribution.

[0029] Specifically, such as Figure 5 As shown, the connecting assembly 9 includes a protective shell 91, which is bolted to the top of the gas distributor 7. The interior of the protective shell 91 is rotatably connected to a hollow shaft 92, and a connecting shaft 93 passes through the left side of the interior of the protective shell 91. The surfaces of the connecting shaft 93 and the hollow shaft 92 are both sleeved with bevel gears 94, and the two bevel gears 94 are meshed with each other.

[0030] Specifically, such as Figure 5 As shown, the left side of the connecting shaft 93 passes through the interior of the inner sleeve 3 and the outer sleeve 2 and extends to the outside of the outer sleeve 2. A plurality of shaft seals 95 are sleeved on the surface of the connecting shaft 93, and the shaft seals 95 are respectively arranged inside the inner sleeve 3 and the outer sleeve 2.

[0031] Specifically, such as Figure 5 As shown, a reduction motor 96 is bolted to the left side of the connecting shaft 93 , and a mounting bracket 97 is bolted to the bottom of the reduction motor 96 , and the mounting bracket 97 is bolted to the outer sleeve 2 .

[0032] In this embodiment, by providing the connecting assembly 9, the connecting shaft 93 can be driven to rotate by the reduction motor 96, and the hollow shaft 92 drives the delivery pipe 81 to rotate under the meshing connection of the two bevel gears 94, thereby achieving the effect of evenly distributing the chlorine gas in the inner sleeve 3, thereby allowing the chlorine gas to fully react with the phosphorus trichloride.

[0033] Specifically, such as Figure 2 、 Figure 5As shown, the top of the hollow shaft 92 is connected to the delivery pipe 81, and the bottom of the hollow shaft 92 is connected to the connecting pipe 10, the bottom of the connecting pipe 10 extends to the bottom of the gas distributor 7, and the bottom of the connecting pipe 10 and the top of the chlorine inlet 6 are both connected to the guide cover 11, and the two guide covers 11 are used in conjunction with each other, and the diameter of the top guide cover 11 is smaller than that of the bottom guide cover 11.

[0034] In this embodiment, by providing the connecting pipe 10 and the flow guide cover 11 , it is possible to achieve the effect of allowing part of the chlorine gas to enter the delivery pipe 81 through the connecting pipe 10 and the hollow shaft 92 .

[0035] Specifically, such as Figure 2 As shown, an interlayer 12 is provided inside the outer sleeve 2, and a cavity 13 is formed between the outer sleeve 2 and the inner sleeve 3. A cooling inlet 14 and a cooling outlet 15 are provided on both sides of the outer sleeve 2 and the inner sleeve 3, respectively, and the cooling inlet 14 and the cooling outlet 15 are connected to the interlayer 12 and the cavity 13, respectively.

[0036] Specifically, such as Figure 2 As shown, a temperature sensor 16 and a pressure sensor 17 are bolted to both sides of the top of the outer sleeve 2 , and the bottoms of the temperature sensor 16 and the pressure sensor 17 extend to the interior of the inner sleeve 3 .

[0037] Specifically, such as Figure 2 、 Figure 3 As shown, the inner wall of the inner sleeve 3 is provided with a spiral protrusion 18 , and the direction of the spiral protrusion 18 is consistent with the rotation direction of the distribution component 8 .

[0038] In this embodiment, the provision of the interlayer 12, the cavity 13, the cooling inlet 14, and the cooling outlet 15 allows for multiple control of the reaction temperature within the reactor body 1, thereby improving the quality of the finished phosphorus pentachloride blocks. Furthermore, the provision of the temperature sensor 16 and the pressure sensor 17 facilitates control of the temperature and pressure within the reactor body 1. Furthermore, the provision of the spiral protrusion 18 guides the chlorine gas to drive the phosphorus trichloride to rotate within the tank body, thereby increasing the dwell time of the two substances within the inner sleeve 3 and further promoting the contact reaction between the phosphorus trichloride and the chlorine gas.

[0039] Working principle: When phosphorus pentachloride is synthesized in the reactor body 1, the liquid phosphorus trichloride is atomized into fine particles through the atomizer 5, and chlorine is introduced through the chlorine inlet 6 at the same time. Under the action of the gas distributor 7, part of the chlorine is distributed in the inner sleeve 3, while the other part of the chlorine enters the interior of the delivery pipe 81 through the connecting pipe 10 and the hollow shaft 92, and is distributed to multiple branch pipes 83 through the connecting plate 82, and is then sprayed into the inner sleeve 3 through the nozzle 84, so that the chlorine can be evenly distributed at different radial positions in the inner sleeve 3. At the same time, the connecting shaft 93 is driven to rotate by the reduction motor 96, and under the meshing connection of the two bevel gears 94, the hollow shaft 92 drives the conveying pipe 81 to rotate, thereby achieving the effect of evenly distributing the chlorine gas in the inner sleeve 3, thereby allowing the chlorine gas and phosphorus trichloride to fully react. Finally, the spiral protrusion 18 can guide the chlorine gas to drive the phosphorus trichloride to rotate in the tank body, thereby increasing the residence time of the two substances in the inner sleeve 3, further promoting the contact reaction between the phosphorus trichloride and chlorine gas, and the phosphorus pentachloride synthesized by the reaction is discharged through the discharge port at the bottom.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
