[0024] Example

[0025] Please refer to Figs. 1 to 4 The utility model provides a long-diameter ratio optimized heavy pipe type reactor structure, including: first reaction tube 1 and second reaction tube 2, first reaction tube 1 and second reaction tube 2 can be detachably connected;Wherein, first reaction tube 1 is equipped with the temperature control component for adjusting the temperature in first reaction tube 1, and the inside of second reaction tube 2 is equipped with mixing conveying piece for strengthening the mixing effect of fluid medium that is transferred out from the inside of first reaction tube 1, the temperature in the reactor can be accurately controlled through temperature control component, ensures that the reaction is carried out in the optimum temperature interval, effectively reduces the occurrence of side reaction, improves product quality and production efficiency, through mixing conveying piece, the mixing effect of material is further strengthened, promotes the full reaction, improves raw material utilization and product quality.

[0026] Wherein, temperature control component includes the temperature control pipe 4 of the sleeve that sets in first reaction tube 1 outside, and the inner wall of temperature control pipe 4 and the outer wall of first reaction tube 1 form temperature control cavity 5, and temperature control cavity 5 is fixedly connected with liquid inlet pipe 401 and liquid outlet pipe 402, still including temperature sensor 102, temperature sensor 102 is fixedly installed on the inner wall of first reaction tube 1, and the temperature in first reaction tube 1 can be accurately adjusted through the temperature control cavity 5 formed between temperature control pipe 4 and first reaction tube 1, cooperate liquid inlet pipe 401 and liquid outlet pipe 402, through temperature sensor 102 real-time monitoring the temperature in first reaction tube 1, so that timely adjust the flow and temperature of fluid in temperature control cavity 5, ensure that the reaction is carried out in the suitable temperature interval, in addition, liquid inlet pipe 401 and liquid outlet pipe 402 are equipped with at least three groups, are installed at both ends of first reaction tube 1 and middle part respectively, the quick input and output of temperature control fluid are convenient.

[0027] The interior of the first reaction tube 1 is provided with a spiral conveying plate 101, which penetrates the entire interior of the first reaction tube 1. The spiral conveying plate 101 guides the fluid to flow along a spiral path, effectively enhancing the mixing effect of the fluid. On the one hand, the spiral flow increases the contact area and time of the fluid with the pipe wall, strengthening the heat transfer process. In reactions requiring rapid heating or cooling, the spiral conveying plate can accelerate heat transfer, allowing the material to quickly reach the required reaction temperature, improving the reaction rate. On the other hand, it promotes the mixing of the material in the pipe, avoiding excessive local concentration differences, which is beneficial to improving the uniformity and efficiency of the reaction.

[0028] The outer wall and the inner wall of the first reaction tube 1 are coated with a heat-conducting coating, which is a ceramic-based heat-conducting coating with a thickness of 100 microns. The ceramic-based heat-conducting coating effectively improves the heat-conducting performance of the first reaction tube 1. During the heat transfer process, heat can be quickly and efficiently transferred between the temperature control cavity 5 and the material inside the first reaction tube 1, reducing heat loss and improving energy utilization efficiency. Especially in reactions with high heat transfer efficiency requirements, the heat-conducting coating can effectively shorten the heating or cooling time, reduce energy consumption, and improve the overall performance of the reactor. In addition, the ceramic-based heat-conducting coating has strong corrosion resistance and can resist the erosion of various chemicals, prolonging the service life of the first reaction tube 1.

[0029] The mixing conveying member includes a plurality of baffles 201 fixedly installed inside the second reaction tube 2. The baffles 201 are arranged in a staggered manner, and a plurality of perforations 202 are formed on the baffles 201. The baffles 201 arranged in a staggered manner and having perforations 202 inside the second reaction tube 2 effectively enhance the mixing effect of the fluid medium. When the fluid flows through the baffles 201, it is divided into multiple streams by the perforations 202, changes the flow direction, and collides and mixes with each other, further increasing the contact opportunities between the fluids and improving the mass transfer efficiency. This allows the reactants to fully contact, accelerates the reaction rate, improves the reaction conversion rate, and makes the reaction more thorough.

[0030] The diameter of the first reaction tube 1 is smaller than the diameter of the second reaction tube 2. The smaller diameter of the first reaction tube optimizes the fluid flow state in the reactor. During the heat transfer stage of the first reaction tube 1, the smaller diameter can increase the fluid flow rate and enhance the convective heat transfer coefficient, accelerating heat transfer. In the mass transfer stage of the second reaction tube 2, the larger diameter provides more space for the fluid, which is beneficial for the diffusion and mixing of the fluid, allowing gas-liquid or liquid-liquid reactions to occur in a more suitable space, improving the mass transfer effect. The combination of the two improves the efficiency of the entire reaction process.

[0031] The butt joint ends of the first reaction tube 1 and the second reaction tube 2 are respectively provided with flanges, and the flanges are fixedly connected through bolts 3. Through the fixed connection mode of the flanges and the bolts 3, the installation and disassembly are facilitated, the operation can be quickly and conveniently completed when the reactor is assembled, maintained and the reaction tube is replaced according to different reaction requirements, meanwhile, the flange connection has good sealing performance, can effectively prevent the leakage of reaction materials, and ensures the safe and stable operation of the reactor under harsh conditions such as high pressure and high temperature.

[0032] The inner wall of the temperature control pipe 4 and the outer wall of the first reaction tube 1 are fixedly connected with a support column 403, which plays a role in stabilizing the relative position of the first reaction tube 1 and the temperature control pipe 4. During the operation of the reactor, especially when the fluid flows at high speed or the temperature and pressure change, the support column 403 can prevent displacement or deformation between the temperature control pipe 4 and the first reaction tube 1, ensure the uniformity and stability of the temperature control cavity 5, and further ensure that the temperature control component can continuously and stably play a role to maintain the precise control of the temperature in the first reaction tube 1.

[0033] The temperature sensor 102 is of PT100 type.

[0034] As known by those skilled in the art, the working principle and wiring method of the temperature sensor 102 are common, which belong to conventional means or common general knowledge, and will not be described here. Those skilled in the art can select the type of the temperature sensor 102 according to their needs or convenience.

[0035] Working principle: when in use, the fluid medium enters from one end of the first reaction tube 1, the internal spiral conveying plate 101 pushes the fluid medium to advance in the tube, the temperature sensor 102 installed on the inner wall of the first reaction tube 1 monitors the temperature in the tube in real time, when the temperature deviates from the preset range, the liquid flow of the liquid inlet pipe 401 and the liquid outlet pipe 402 is adjusted, the liquid in the temperature control cavity 5 is used to heat or cool the first reaction tube 1, so as to ensure that the reaction is carried out at a suitable temperature. The heat-conducting coating on the inner and outer walls of the first reaction tube 1 helps heat transfer and improves temperature control efficiency. The fluid medium that has been preliminarily reacted and transitioned in the first reaction tube 1 enters the inside of the second reaction tube 2, the multiple baffles 201 with perforations 202 arranged in a zigzag manner in the second reaction tube 2 block and divide the fluid medium, strengthen the mixing effect of the fluid medium, and promote further reaction.
