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.
[0023] Embodiment: This embodiment is used to solve the problem that water impacts the reactor but does not diffuse, resulting in insufficient contact between the water and the heat required to release or absorb heat in the reactor, which further leads to limited temperature changes in the reactor.

[0025] The partition plate 3 is provided with through holes 4 distributed in a circumferential array, and a skirt belt 8 is installed on the outer edge side of the lower surface of the partition plate 3;
[0026] A feed port 2 is provided through the middle position of the top of the kettle body 1 corresponding to the two adjacent water inlet pipes 7. The extension line of the feed port 2 is also in contact with the outer wall of the arc plate 5. The inner wall of the water inlet pipe 7 and the outer walls of the inner pipe body 11 and the branch pipe body 12 together form a main water injection chamber 10. The main water injection chamber 10 discharges clean water into the bearing ring 6 through the inclined section and the horizontal section of the water inlet pipe 7.
[0027] See also Figure 3 As shown, in the production process of organic peroxide, after the material enters the kettle body 1 through the feed port 2, part of it is accumulated at the bottom of the kettle body 1 and part of it is retained on the partition plate 3. Clean water is pumped into the kettle body 1 through the water inlet pipe 7, and the clean water enters the water injection cavity 10 in the water inlet pipe 7 and is divided into two parts, namely, the main water injection cavity 10 and the auxiliary water injection cavity. The first part flows into the inner tube body 11, and the second part flows into the carrying ring 6 along the end of the water inlet pipe 7.
[0028] For the first part: see Figure 3 - Figure 5 As shown, the clean water in the inner tube body 11 directly impacts the arc disk 5, and is replenished in a manner of splashing around. The inner tube body 11 is simultaneously diverted outward through the branch tube body 12 and impacts the upper surface of the splash cover 9. The clean water splashes from the surroundings to the middle of the splash cover 9, so that the clean water also splashes around and has an accompanying flushing effect, so that the materials bonded to the inner wall of the kettle body 1 on the upper side of the partition plate 3 are washed and removed. In summary, the materials on the partition plate 3 are impacted by the splashing water and fall through the through hole 4 to the bottom of the kettle body 1, and the splashing water is synchronously poured from the through hole 4 to the bottom of the kettle body 1, so that the materials at the bottom of the kettle body 1 corresponding to the bottom side of the through hole 4 are evenly replenished.
[0029] The upper end of the bearing ring 6 is sealed with a splash cover 9, the inner top end of the splash cover 9 is fixedly connected with a guide column 13, the bottom of the guide column 13 is provided with a guide edge 14 whose cross section forms a 45° angle with the horizontal section of the water inlet pipe 7, the splash cover 9 is a hemispherical body with a hollow structure, the extension line of the branch pipe body 12 is connected to the outer wall of the splash cover 9, the extension line of the end of the inner pipe body 11 passing through the water inlet pipe 7 is connected to the outer wall of the arc disk 5, the interior of the inner pipe body 11 and the branch pipe body 12 constitutes a secondary water injection cavity, and the secondary water injection cavity discharges clean water to the arc disk 5 and the top of the splash cover 9;
[0030] For the second part: see Figure 3 - Figure 5 As shown, clean water is fed into the bearing ring 6 through the connecting sleeve 16 at the end of the water inlet pipe 7, and the clean water horizontally hits the guide edge 14 at the bottom of the guide column 13. Since the cross-sectional angle of the guide edge 14 is 45°, the main part of the clean water impact flow is in the form of vertical downward showering, and the rest is scattered and showered to the bottom of the kettle body 1. From the cross-sectional observation, the clean water is showered in a fan-shaped manner to complete the uniform water replenishment of the material in the middle position of the bottom of the kettle body 1.
[0031] Combining the first and second methods of clean water replenishment, the clean water can be impacted and sprinkled in various ways in the reactor when replenishing water. The clean water impact method of the first part can be used to complete the uniform impact of the materials on the top of the reactor, and the clean water sprinkling method of the second part can be used to achieve direct water replenishment at the bottom of the reactor. The combination of the two forms a relatively uniform all-round water replenishment, and the clean water impacts the reactor to form an all-round diffusion, so that the clean water is in full contact with the heat that needs to release or absorb heat in the reactor, thereby realizing flexible changes in temperature changes in the reactor.
