The chlorine recovery pipe is installed at the top right of the vessel body. A chlorine delivery pipe is installed between the chlorine recovery pipe and the chlorine charging pipe. The LCD screen interacts with the pressure gauge, the chlorine delivery pipe, and the discharge pipe via sensors.

[0004] Regarding the aforementioned technologies, the inventors have discovered at least the following problems: when chlorine enters the tank, due to the generally large size of the tank, the chlorine cannot quickly and fully contact and react with the sodium cyanurate solution inside the tank, resulting in low production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a pipeline reaction apparatus for preparing trichloroisocyanuric acid, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipeline reaction apparatus for preparing trichloroisocyanuric acid, comprising a reaction tank, a pre-reaction mechanism, and a dispersion mechanism. A stirring rod is installed inside the reaction tank. The pre-reaction mechanism includes a cylinder disposed on one side of the reaction tank and a four-channel reaction tube disposed within the cylinder. A discharge pipe is fixedly connected to the bottom of the reaction tank. A circulation pump is connected to one end of the discharge pipe. A first feed pipe is connected to the outlet end of the circulation pump. One end of the first feed pipe extends into the cylinder and is fixedly connected to a Venturi tube. A chlorine inlet pipe is fixedly connected to one side of the Venturi tube. The lower end of the Venturi tube is fixedly connected to the four-channel reaction tube. A second feed pipe is fixedly connected to the lower end of the four-channel reaction tube. A shell is provided at the top of the reaction tank, and one end of the second feed pipe extends into the shell. The dispersion mechanism includes a rotating tube rotatably mounted on the top of the reaction tank, dispersion tubes fixedly connected to both sides of the rotating tube, a discharge port evenly arranged at the bottom of the dispersion tube, and a driving component for driving the rotating tube to rotate. The upper end of the rotating tube is rotatably connected to the second guide tube, and the lower end of the rotating tube is fixedly connected to the stirring rod.

[0007] In a preferred embodiment, a feed pipe is provided on one side of the top of the reaction vessel.

[0008] In a preferred embodiment, a first valve is provided on the discharge pipe.

[0009] In a preferred embodiment, a second valve is installed on the first feed pipe.

[0010] In a preferred embodiment, a third valve is installed on the chlorine inlet pipe.

[0011] In a preferred embodiment, the driving component includes a motor fixedly installed inside the housing, a main gear fixedly connected to the output end of the motor, and a driven gear meshing with the main gear fixedly installed on the rotating tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This pipeline reaction apparatus for preparing trichloroisocyanuric acid, through the setting of a pre-reaction mechanism, allows the opening of the first, second, and third valves after obtaining a sodium cyanurate solution. Then, the circulation pump is started to pump the sodium cyanurate solution in the reaction tank into the first feed pipe, and then into the Venturi tube. At the same time, chlorine gas enters the Venturi tube from the chlorine gas inlet pipe. Then, the sodium cyanurate solution and chlorine gas enter the four-channel reaction tube together for pre-reaction. Due to the narrow space inside the four-channel reaction tube, the chlorine gas can quickly and fully contact and react with the sodium cyanurate solution, thereby improving the reaction efficiency. This pipeline reaction device for preparing trichloroisocyanuric acid, through the setting of the dispersion mechanism, can activate the drive component to drive the rotating tube to rotate during the reaction process. The pre-reacted solution enters the rotating tube from the second feed pipe and is finally evenly discharged from the outlet at the bottom of the dispersion tube into the reaction tank, where it is fully mixed with the solution in the reaction tank, thereby improving production efficiency.

[0015] The present invention will be further described below with reference to the embodiments.

[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0017] Please see Figure 1-3 This utility model provides a pipeline reaction device for preparing trichloroisocyanuric acid, including a reaction tank 1, a pre-reaction mechanism 2 and a dispersion mechanism 3. A stirring rod 11 is installed inside the reaction tank 1, and a feed pipe 13 is installed on one side of the top of the reaction tank 1. During the reaction, cyanuric acid and sodium alkali are first added into the reaction tank 1 through the feed pipe 13, and the cyanuric acid and sodium alkali are stirred and mixed by the stirring rod 11 to obtain a sodium cyanurate solution.

[0018] Specifically, the pre-reaction mechanism 2 includes a cylinder 21 disposed on one side of the reaction tank 1 and a four-channel reaction pipe 22 disposed inside the cylinder 21. A discharge pipe 23 is fixedly connected to the bottom of the reaction tank 1. A first valve 29 is installed on the discharge pipe 23. One end of the discharge pipe 23 is connected to a circulation pump 24. The outlet end of the circulation pump 24 is connected to a first guide pipe 25. A second valve 210 is installed on the first guide pipe 25. One end of the first guide pipe 25 extends into the cylinder 21 and is fixedly connected to a venturi tube 26. A chlorine inlet pipe 27 is fixedly connected to one side of the venturi tube 26. A third valve 211 is installed on the chlorine inlet pipe 27. The lower end of the venturi tube 26 is fixedly connected to the four-channel reaction pipe 22. A second feed pipe 28 is provided, and a shell 12 is provided on the top of the reaction tank 1. One end of the second feed pipe 28 extends into the shell 12. With the setting of the pre-reaction mechanism 2, after obtaining the sodium cyanurate solution, the first valve 29, the second valve 210 and the third valve 211 can be opened. Then, the circulation pump 24 is started to pump the sodium cyanurate solution in the reaction tank 1 into the first feed pipe 25. After passing through the first feed pipe 25, it enters the Venturi tube 26. At the same time, chlorine gas enters the Venturi tube 26 from the chlorine gas inlet pipe 27. Then, the sodium cyanurate solution and chlorine gas enter the four-channel reaction tube 22 together for pre-reaction. Because the space inside the four-channel reaction tube 22 is narrow, the chlorine gas can quickly and fully contact and react with the sodium cyanurate solution, thereby improving the reaction efficiency.

[0019] Specifically, the dispersion mechanism 3 includes a rotating tube 31 rotatably mounted on the top of the reaction tank 1, dispersion tubes 32 fixedly connected to both sides of the rotating tube 31, a discharge port 33 uniformly arranged at the bottom of the dispersion tube 32, and a driving component 34 for driving the rotating tube 31 to rotate. The upper end of the rotating tube 31 is rotatably connected to the second guide tube 28, and the lower end of the rotating tube 31 is fixedly connected to the stirring rod 11. With the setting of the dispersion mechanism 3, during the reaction process, the driving component 34 can be activated to drive the rotating tube 31 to rotate. The pre-reacted solution enters the rotating tube 31 from the second guide tube 28 and is finally uniformly discharged into the reaction tank 1 from the discharge port 33 at the bottom of the dispersion tube 32, where it is fully mixed with the solution in the reaction tank 1, further improving production efficiency.

[0020] Specifically, the drive unit 34 includes a motor 341 fixedly installed in the housing 12. The output end of the motor 341 is fixedly connected to a main gear 342. A driven gear 343 that meshes with the main gear 342 is fixedly installed on the rotating tube 31. The motor 341 can be started to drive the main gear 342 to rotate, which in turn drives the driven gear 343 to rotate, which in turn drives the rotating tube 31 to rotate.

[0021] The working principle and usage process of this utility model are as follows: First, during the reaction, cyanuric acid and sodium alkali are added into the reaction tank 1 through the feed pipe 13, and the drive unit 34 is started to drive the rotating pipe 31 to rotate, which in turn drives the stirring rod 11 to rotate. The stirring rod 11 stirs and mixes the cyanuric acid and sodium alkali to obtain a sodium cyanurate solution. After obtaining the sodium cyanurate solution, the first valve 29, the second valve 210, and the third valve 211 can be opened. Then, the circulation pump 24 is started to pump the sodium cyanurate solution in the reaction tank 1 into the first feed pipe 25. The solution enters the Venturi tube 26 through the first feed pipe 25, while chlorine gas enters the Venturi tube 26 through the chlorine gas inlet pipe 27. Then, the sodium cyanurate solution and chlorine gas enter the four-channel reaction tube 22 together for pre-reaction. Due to the narrow space within the four-channel reaction tube 22, the chlorine gas can quickly and fully contact and react with the sodium cyanurate solution. The pre-reacted solution enters the rotating tube 31 through the second feed pipe 28, and finally is evenly discharged into the reaction tank 1 from the outlet 33 at the bottom of the dispersion tube 32, where it is fully mixed with the solution in the reaction tank 1, improving production efficiency. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
