Description

Technical Field

[0001] This utility model relates to the technical field of tower reactor equipment in industries such as chemical, pharmaceutical and environmental protection. Specifically, it relates to an internal device of a tower reactor that integrates spraying and stirring functions. It is particularly suitable for scenarios that require uniform spraying, precise flow control and efficient mixing of reaction media. It can be used in tower reactors for multiphase reaction processes such as liquid-liquid and liquid-gas. Background Technology

[0002] Existing tower reactor spraying devices are mostly simple structures consisting of a single pipe and spray heads. The spraying range is limited and unevenly distributed, which can easily lead to incomplete local reactions. This is especially true in large tower reactors, where the spraying medium cannot cover the entire cross-section of the reactor. Traditional spraying systems rely on external valves for flow regulation, making it impossible to adjust the flow rate of the medium at different locations within the spray pipe in real time and with precision. When the viscosity or pressure of the medium changes, it can easily lead to excessive differences in flow rate at each spray point, affecting reaction stability. In most tower reactors, the spraying device and the stirring device are independent of each other. The sprayed medium is difficult to mix quickly with the original materials in the reactor during its descent, which can easily lead to excessively high local concentrations or delayed reactions, reducing the overall reaction efficiency.

[0003] Therefore, it is necessary to design a spray device for a tower reactor to solve the problems mentioned above. Utility Model Content

[0004] To address the problems of existing tower reactor spraying devices in terms of spray uniformity, flow rate adjustment accuracy, equipment durability, reaction efficiency, and ease of maintenance, this utility model provides a spraying device for tower reactors. By integrating spraying and stirring functions and optimizing pipeline structure and connection methods, it achieves efficient spraying and mixing of the reaction medium, thereby improving the overall performance of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A spraying device for a tower reactor includes a tower reactor, a spraying assembly, and a stirring assembly, which work together to complete the process of conveying, spraying, and mixing the reaction medium.

[0007] Furthermore, the tower reactor serves as a reaction vessel, with feed pipe, discharge pipe, liquid pipe, and gas pipe connected to its outer side. The feed pipe is used to transport the materials to be reacted into the reactor, the discharge pipe is used to discharge the reaction products, the liquid pipe is used to introduce the medium required for spraying, and the gas pipe is used to introduce the gas required for the reaction or to discharge the gas generated by the reaction. The connection positions of each pipe to the reactor are set according to the reaction process requirements to ensure the smooth transport of materials and media.

[0008] Furthermore, the spray assembly is located inside the tower reactor, and its top is fixed to the inner top of the tower reactor by a fixing rod made of high-strength metal to ensure the stability of the spray assembly during operation. The spray assembly includes a connecting sleeve, multiple auxiliary conveying pipes, a spray pump, spray heads, and a flow regulating component. The connecting sleeve is connected to the fixing rod, and the multiple auxiliary conveying pipes are distributed around the connecting sleeve and interconnected through the cavity inside the connecting sleeve to form a branched conveying structure, which can evenly distribute the medium to each auxiliary conveying pipe. Each auxiliary conveying pipeline has a spray head connected to its bottom via a spray pump. The spray pump provides power for the media to be sprayed, ensuring that the spray head can spray the media at the appropriate pressure and flow rate. The auxiliary conveying pipeline also has multiple flow regulation components inside. Each flow regulation component includes an adjusting sealing plate that is rotatably connected to the inner wall of the auxiliary conveying pipeline via a hinge. The overall shape and size of the adjusting sealing plate match the internal shape and size of the auxiliary conveying pipeline. By adjusting the rotation angle of the sealing plate around the hinge, the flow cross-sectional area inside the pipeline can be changed, thereby achieving precise adjustment of the media flow rate at that location to adapt to different spraying needs.

[0009] Furthermore, multiple auxiliary delivery pipelines are ultimately connected to the main delivery pipeline through the internal cavity of the connecting sleeve. The bottom of the main delivery pipeline is connected to the delivery pump body via a rotary joint. The rotary joint reduces wear caused by relative movement between the main delivery pipeline and the delivery pump body, improving the durability of the connection. The input end of the delivery pump body is connected to the end of the liquid pipe via a connecting hose. The connecting hose has a certain degree of flexibility, facilitating the installation and positioning adjustment of the delivery pump body. A protective sleeve is installed on the outside of the delivery pump body. The protective sleeve is made of wear-resistant and corrosion-resistant materials, which protects the delivery pump body and extends its service life. Both the main and auxiliary delivery pipelines are made of corrosion-resistant alloy materials, specifically stainless steel alloy or titanium alloy, and their surfaces are also coated with an anti-corrosion coating. The anti-corrosion coating can be polytetrafluoroethylene coating or ceramic coating, further enhancing the corrosion resistance of the pipelines and enabling them to adapt to the transportation environment of corrosive media such as acids and alkalis.

[0010] Furthermore, the stirring assembly is located below the spraying assembly and is connected in conjunction with it. It includes a drive motor, a rotating shaft, and multiple stirring blades. The drive motor is embedded in the bottom of the tower reactor to provide power for stirring. The output end of the drive motor is connected to the rotating shaft, and multiple stirring blades are arranged around the outside of the rotating shaft. The shape and angle of the stirring blades are designed according to the stirring requirements, which can efficiently promote the flow of materials in the reactor. The top of the rotating shaft is also rotatably connected to the bottom of the protective sleeve through a rotary joint. The rotary joint ensures the stability of the rotating shaft during high-speed rotation and reduces friction between it and the protective sleeve, enabling the stirring assembly to rotate stably and fully stir the materials inside the tower reactor, promoting rapid mixing of the sprayed medium with the original materials.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, a spraying device for a tower reactor achieves the following effects: 1. By using multiple auxiliary conveying pipes distributed around the reactor in conjunction with spray heads, the coverage area of ​​the spraying medium within the tower reactor is expanded, solving the problem of limited spraying range in traditional single-pipe systems and ensuring that the reaction medium can uniformly contact the materials within the reactor; 2. Utilizing the flow regulation components inside the auxiliary conveying pipes, the flow rate of the medium at different locations within the pipes can be adjusted in real time in segments, solving the problem of insufficient adjustment precision of traditional external valves, adapting to the spraying requirements of media with different viscosities and pressures, and ensuring stable flow at each spraying point; 3. The main and auxiliary conveying pipes are made of corrosion-resistant alloy material and have an anti-corrosion coating, improving their resistance to corrosive media such as acids and alkalis and extending their service life; at the same time, the rotary joint connecting the pump body reduces wear at the connection points due to vibration and impact, improving the stability of the device; 4. A stirring component is installed below the spraying component, allowing the sprayed medium to quickly mix with the materials in the reactor under the action of the stirring blades, solving the problem of insufficient mixing caused by the independent operation of traditional spraying and stirring, accelerating the reaction rate, and improving the uniformity of product quality.

[0023] Please see Figure 3Based on embodiment 1, this embodiment further defines the spray assembly 2 as including a connecting sleeve 21, an auxiliary conveying pipe 22, a spray pump 23, a spray head 24, and a flow regulating assembly 25. The connecting sleeve 21 is fixedly connected to the fixing rod 8, and multiple auxiliary conveying pipes 22 are distributed around the connecting sleeve 21 and communicate with the cavity inside the connecting sleeve 21. Each auxiliary conveying pipe 22 has a spray head 24 connected to its bottom via a spray pump 23. The spray pump 23 provides sufficient pressure to the spray medium, allowing the spray head 24 to spray the medium evenly. The auxiliary conveying pipe 22 is equipped with multiple flow regulating components 25. Each flow regulating component 25 includes a hinge 251 and an adjusting sealing plate 252.

[0024] Example 3

[0025] Please see Figure 3 as well as Figure 4 This embodiment, based on embodiment 1, further defines multiple auxiliary conveying pipes 22 that are interconnected through the cavity inside the connecting sleeve 21 and ultimately connected to the main conveying pipe 26.

[0028] The working process of this utility model is as follows: When using the spray device of the tower reactor, the material to be reacted is first introduced into the tower reactor 1 through the feed pipe 4, and the gas required for the reaction is introduced into the tower reactor 1 through the gas pipe 7; at the same time, the spray medium is transported to the connecting hose 281 through the liquid pipe 6, powered by the conveying pump body 28, and pumped into the connecting sleeve 21 through the main conveying pipe 26. The spray medium entering the connecting sleeve 21 is diverted to multiple auxiliary conveying pipes 22 distributed around it. The flow regulating component 25 inside the auxiliary conveying pipe 22 precisely controls the flow rate of the medium in each section of the pipe by adjusting the rotation of the sealing plate 252 around the hinge 251, ensuring... The spray pressure is stable. The medium, after flow regulation, is pressurized by the spray pump 23 and evenly sprayed into the tower reactor 1 through the spray head 24, covering most of the cross-section of the reactor and achieving initial contact with the material to be reacted. The drive motor 31 is started, driving the rotating shaft 32 and the surrounding stirring blades 33 to rotate.
