Description
Technical Field
[0001] The utility model relates to the technical field of chemical equipment, and particularly relates to a feed distribution device for a hydrogenation reactor. Background Art
[0002] A hydrogenation reactor is a device widely used in petroleum refining and chemical production, mainly used for carrying out chemical reactions between hydrogen and hydrocarbon compounds to improve the quality of products or change their properties. During the operation of a hydrogenation reactor, the uniformity of feed distribution has an important impact on the reaction rate and the service life of the catalyst. Hydrogenation reactions usually need to be carried out under high temperature and high pressure conditions. The uniformity of feed distribution directly affects the contact efficiency of reactants on the catalyst surface, thereby affecting the rate and selectivity of the entire reaction. The catalyst is a key component in the hydrogenation reaction, and its activity and selectivity directly affect the quality of the product. Uniform feed distribution helps to evenly utilize the catalyst, avoid local overload, and extend the service life of the catalyst.
[0003] In actual use, if the feed distribution device lacks a uniform dispersion component, it may lead to uneven distribution of reactants in the reactor, thereby causing local reactions to be too fast or too slow, affecting the overall reaction rate. If the reactants cannot evenly contact the catalyst surface, some catalysts may not be fully utilized, resulting in a decrease in catalyst efficiency. Uneven feed distribution may lead to too high temperature or concentration in local areas, increasing the occurrence of side reactions and affecting product quality. The uneven distribution of temperature inside the reactor will increase the difficulty of temperature control, may cause local overheating, affecting the stability and safety of the reactor. Uneven material flow may lead to too high local flow rate, increasing the pressure drop of the system, thereby increasing energy consumption. Summary of the Utility Model

A shunt groove 9 is formed on the outer circumference of the shunt pipe 10, and its function is to increase the flow area of the materials in the shunt pipe 10 and improve the distribution efficiency.
[0026] The number of the fixed columns 4 is three, and its function is to provide a more stable support structure. The bottom ends of the fixed columns 4 and the motor 3 cooperate with each other, and its function is to ensure that the motor 3 is stably installed on the fixed column 4.

[0027] Working principle: First, install the fixed column 4 at the top of the tank body 1. The fixed column 4 provides a stable support point for the entire device, and its uniform distribution helps to maintain the structural balance. Install the motor 3 at the top of the fixed column 4. The tight fit between the motor 3 and the fixed column 4 ensures that the motor will not displace during operation, thus ensuring the stability of power transmission. Connect the output end of the motor 3 to the rotating column 8. The connection between the output end of the motor 3 and the rotating column 8 is the key to power transmission, ensuring that the power of the motor can be effectively transmitted to the rotating column 8. Install the input pipe 2 at the top of the tank body 1. The rotating column 8 penetrates the outer ring of the input pipe 2. The input pipe 2 serves as a channel for the material to enter. The fact that the rotating column 8 penetrates its outer ring enables the material to be preliminarily dispersed under the action of the rotating column 8. Install the rotating blades 5 at the bottom end of the rotating column 8. The number of rotating blades 5 is five. The uniform distribution of the rotating blades 5 helps the material to achieve a wider distribution under the drive of the rotating column 8. The design of five blades can provide sufficient dispersing force. Use the fastening bolts 7 to fix the rotating blades 5 at the bottom end of the rotating column 8. The use of the fastening bolts 7 ensures the stability of the rotating blades 5 during high-speed rotation and prevents the blades from falling off due to vibration or centrifugal force. Fix the diffusion hood 6 to the bottom end of the input pipe 2. The bottom end of the diffusion hood 6 is penetrated by the shunt pipe 10. The diffusion hood 6 is the first contact point after the material enters from the input pipe 2. The shunt pipe 10 at its bottom end further guides the flow direction of the material and provides a channel for the further dispersion of the material. Install several shunt pipes 10 at the bottom end of the diffusion hood 6. The installation of the shunt pipes 10 increases the dispersion points of the material, and the cooperation with the diffusion hood 6 ensures that the material can flow out evenly from multiple directions. Open the shunt grooves 9 on the outer ring of the shunt pipe 10. The design of the shunt grooves 9 expands the flow channel of the material, improves the flow efficiency of the material, and helps to achieve a more uniform material distribution.
