The arch pipe 4 is a symmetrical structure relative to the output pipe 3, and can keep a stable posture in rotation.

[0032] The top end of the arch pipe 4 is in butt joint communication with the bottom end of the output pipe 3.

[0033] The bottom end of the arched pipe 4 is arranged close to the pipe wall of the reaction container 14, two bottom end nozzles 5 are respectively arranged at the two bottom ends of the arched pipe 4, the water outlet directions of the two bottom end nozzles 5 are opposite, the water outlet direction of the bottom end nozzle 5 is horizontal and perpendicular to the plane in which the extension direction of the arched pipe 4 lies, after the water mist is sprayed by the bottom end nozzle 5, the arched pipe 4 can be pushed to rotate, so that the dynamic effect of rotation is obtained.

[0034] The inner side of the arched pipe 4 is provided with three pairs of inner nozzles 6, which are respectively a pair of symmetrical lower nozzles, a pair of symmetrical middle nozzles and a pair of symmetrical upper nozzles, the spraying direction of the inner nozzles 6 is horizontal and inward, based on the curved feature of the arched pipe 4, the installation positions of the inner nozzles 6 from bottom to top gradually change from close to the inner wall of the container to close to the middle of the container, so the spraying positions of the two lower nozzles are closer to the periphery of the container section, and the spraying position of the upper nozzle is relatively close to the middle position of the container section, a top end nozzle 7 which sprays downward is further arranged at the bottom side of the top end of the arched pipe 4, so that the three-dimensional dynamic spraying effect is realized, when the medium is introduced, after the high-pressure high-speed spray is formed, the spraying of the bottom end nozzle 5 pushes the arched pipe 4 to rotate relative to the rotating joint 1, in the rotating process, the lower nozzle, the middle nozzle, the upper nozzle, the top end nozzle 7 and the bottom end nozzle 5 respectively complete the spraying in different dimensions on the relative container section, combined with rotation, the spraying range of each nozzle is a ring-shaped section, and in summary, each corner of the container section is covered, under the condition of a large area section, even if a plurality of or a plurality of annular branch pipes are not arranged, the spraying uniform and sufficient requirement can be considered, and only a single pipeline is required, without the need for power driving, the structure is simple and the cost is low. And the rotation of the arched pipe 4 has the effect of fluid disturbance on the material flowing through, promotes the full mixing and uniformity of the material, improves the mixing effect, or improves the heat exchange effect.

[0035] If it is applied to the demand of cooling or sufficient multiple spraying, a ring-shaped spraying mechanism can be further arranged below the arched pipe 4, the ring-shaped spraying mechanism comprises a circular second header 8, the second header 8 is arranged outside the reaction container 14, the second header 8 is connected to the material conveying pipe network, a plurality of vertical pipes 9 are arranged in the inner ring annular array of the second header 8, the vertical pipes 9 are five and also annularly arranged relative to the reaction container 14, the vertical pipes 9 are arranged close to the inner wall of the reaction container 14, the bottom end of the vertical pipe 9 is provided with a connecting pipe 10 which extends vertically and horizontally, the outer end of the connecting pipe 10 penetrates the reaction container 14 and is connected to the second header 8, so as to realize communication.

[0037] The annular spraying mechanism does not occupy the cross-sectional space in the reaction container 14. It does not affect the flow and sufficient reaction / cooling of the material. The material disturbed by the rotation of the arch-shaped pipe 4 continues to mix and uniform in the interference-free cavity range, and forms a continuous spraying environment on the periphery, promoting further reaction or cooling. Although the side nozzle 11 is arranged on the wall and forms a spray on the periphery, after the rotation and spraying of the arch-shaped pipe 4 above, a certain spiral airflow and disturbance airflow is generated, which can continuously form airflow continuous mixing and disturbance in the side nozzle 11, promoting uniform contact.

[0038] The example first rotates and sprays through the arch-shaped pipe 4. With the extension characteristics of the arch-shaped pipe 4, the installation layout of the nozzle from outside to inside is realized through one pipe, which realizes spraying care on the entire cross section in a large range, and the rotation of the arch-shaped pipe 4 and the rotation of the spray promote the strong disturbance and mixing of the airflow, so that it can continue to mix and uniform when passing through the side nozzle 11 below, obtain a long-distance spraying environment, and realize the effects of continuous spraying, continuous reaction, and continuous cooling.

[0041] Through the cooperation of the reverse nozzles 13 and the side nozzles 11, when the arch-shaped pipe 4 rotates, the reverse nozzles 13 rotate to realize rotation and horizontal spraying in the middle to the periphery. At the same time, the side nozzles 11 spray inward on the periphery of the reaction container 14 to realize care and coverage of a large cross-sectional range. At the same time, the central pipe 12 hardly occupies the cross-sectional space, and greatly improves the spraying coverage capacity by increasing the single-pipe consumables.
