Description

Technical Field

[0001] The utility model relates to the technical field of reflux distributors, and particularly relates to an efficient frame-type reflux distributor. Background Technique

[0002] A reflux distributor is a gas-liquid or liquid-liquid separation device used in industrial processes. Its main function is to evenly distribute the reflux liquid onto the tray or packing, thereby improving the separation efficiency. Such distributors are usually applied in distillation columns, absorption columns, and reaction columns. During use, the fluid distribution of traditional reflux distributors is uneven, prone to fluid concentration and dead zones, resulting in poor mixing effect, low mass transfer efficiency, affecting the overall performance. At the same time, the flow resistance is large, the eddy current phenomenon is serious, and the fluid distribution is not smooth. Content of the Utility Model

A diffusion plate is fixedly installed inside the frame. The surface of the diffusion plate is provided with openings. A flow guide plate is fixedly installed inside the frame. The surface of the flow guide plate is provided with flow guide holes. A perforated plate is fixedly installed at the bottom of the frame.

[0005] Preferably, the overall material of the frame is selected as 316L stainless steel. Here, 316L stainless steel has high mechanical strength and toughness, ensuring the stability and reliability of the distributor during long-term use under harsh conditions such as high pressure and high temperature.

[0006] Preferably, the number of the flow guide plates is three groups. The three groups of flow guide plates are equidistantly distributed inside the frame, and the flow guide plates are parallelly distributed in the vertical direction. Here, it can evenly distribute the fluid, avoid fluid concentration or dead zones, thereby improving the mixing effect and mass transfer efficiency of the fluid, enhancing the stability of the overall structure, and contributing to maintaining the structural integrity and functional stability of the distributor during operation.

[0007] Preferably, the cross-sections of the diffusion plate, the flow guide plate, and the perforated plate are consistent with the cross-section of the frame. Here, it reduces the resistance and eddy current phenomenon during fluid flow, ensuring more uniform and smooth fluid distribution.

[0008] Preferably, the flow guide plate and the frame are fixedly connected by welding or bolts. Here, it ensures the stable connection between the flow guide plate and the frame, reducing the risk of loosening or falling off caused by vibration or impact.

[0009] Preferably, a housing is fixedly installed on the surface of the inlet, a water inlet is fixedly installed on the surface of the housing, a filling layer is fixedly installed inside the housing, and the filling layer uses ceramic fillers. Here, the housing provides additional protection for the inlet, reduces the influence of the external environment on the inlet, extends the service life of the equipment, and can buffer the water flow entering the distributor, eliminate uneven liquid flow velocity, and ensure the stability of the liquid before entering the distributor.

[0010] Preferably, an upper flange is fixedly installed on the bottom surface of the housing, a lower flange is fixedly installed on the surface of the inlet, and the upper flange and the lower flange are fixedly connected by quick-release bolts. Here, the flange connection method provides reliable sealing performance, prevents leakage, and ensures the safe operation of the distributor.

[0012] 1. In the present utility model, the openings formed on the surface of the diffusion plate and the three groups of equally spaced flow guiding plates inside the frame can evenly distribute the fluid, avoid fluid concentration or dead corners, improve the mixing effect and mass transfer efficiency of the fluid. The parallel distribution of the flow guiding plates and their firm connection with the frame enhance the stability of the overall structure, ensure the maintenance of the structural integrity and functional stability of the distributor during operation. The cross-sections of the diffusion plate, the flow guiding plate, and the porous plate are consistent with the frame, reducing the resistance and vortex phenomena during the fluid flow process, ensuring more uniform and smooth fluid distribution, and achieving efficient, stable, and safe fluid distribution.

[0013] 2. In the present utility model, the housing fixedly installed on the surface of the inlet and the ceramic fillers inside it provide additional protection for the inlet, reduce the influence of the external environment on the inlet, extend the service life of the equipment.
