Description

Technical Field

[0001] This utility model relates to the field of fractionation tower technology, specifically to a fractionation tower wall flow redistributor device. Background Technology

[0002] A fractionation column is a device used to separate liquid mixtures. It evaporates liquids of different components by heating them inside the column and separates them based on their differences in boiling point. Fractionation columns are widely used in petroleum, chemical, and pharmaceutical industries to separate different components in liquid mixtures to meet the needs of production processes.

[0003] During the fractionation process, liquid may flow along the column wall due to various reasons. This phenomenon may adversely affect the separation efficiency of the fractionation column, easily leading to uneven liquid layer distribution on the column plate, which in turn affects the contact efficiency of the gas and liquid phases. Therefore, it is necessary to provide a fractionation column wall flow redistributor device. Utility Model Content

[0004] The purpose of this utility model is to provide a fractionating tower wall flow redistributor device to solve the problem mentioned in the background art, which may adversely affect the separation efficiency of the fractionating tower, easily leading to uneven liquid layer distribution on the tray, and thus affecting the contact efficiency of the gas and liquid phases. To achieve the above objective, this utility model provides the following technical solution: a fractionating tower wall flow redistributor device, including a fixed base, a distribution component on the top of the fixed base, the distribution component including a fractionating tower body, the fractionating tower body being fixedly connected to the top of the fixed base, a redistributor body being fixedly connected to the inner wall of the fractionating tower body, a water collection tank on the top of the redistributor body, a drain hole on one side of the water collection tank, and a drainage hole on the top of the redistributor body. By installing the distribution component, the flow can be redistributed in the fractionating tower... During fractionation, the gas produced by fractionation adheres to the inner wall of the fractionation tower and then condenses into liquid. Water droplets on the inner wall of the fractionation tower then flow down the tower wall and collect in the water collection tank. The water in the water collection tank then flows through the drain hole to the top of the redistributor body, and then through the drain hole to the bottom guide plate. The water on the guide plate then flows through the guide channel to the bottom of the fractionation tower, thus achieving redistribution of the wall flow. This avoids the liquid wall flow from adversely affecting the separation efficiency of the fractionation tower and improves the overall mass transfer efficiency.

[0005] More preferably, a water guide plate is fixedly connected to the inner wall of the fractionation tower body, and a water guide groove is provided on the top of the water guide plate.

[0006] More preferably, a distillation tower top plate is fixedly connected to the top of the distillation tower body, and a condenser connector is fixedly connected to the top of the distillation tower top plate.

[0007] More preferably, a liquid inlet is fixedly connected to the side surface of the fractionation tower body, and an outlet is fixedly connected to the side surface of the fractionation tower body.

By installing the heater, the necessary heat passing through the heater can be used and transported to the interior of the main body of the fractionation tower through the heat exchange tube, so that the components in the mixture can reach their respective boiling points, thereby realizing vaporization and separation, and improving the practicality of the device.

[0009] More preferably, the main body of the fractionation tower is internally connected to a discharge pipe, which is fixedly connected to one side of the fixed base, and a control valve is fixedly connected to the side surface of the discharge pipe.

The water in the water collection tank will then flow through the drain hole to the top of the redistributor body, and then through the drain hole to the bottom guide plate. The water on the guide plate will then flow through the guide trough to the bottom of the fractionation tower body, thereby realizing the redistribution of the wall flow, avoiding the adverse effect of the liquid wall flow on the separation efficiency of the fractionation tower body, and improving the overall mass transfer efficiency.

[0012] In this invention, by installing a heater, the necessary heat passing through the heater can be transported to the interior of the fractionation tower body through heat exchange tubes, thereby enabling the components in the mixture to reach their respective boiling points, thus achieving vaporization and separation, and improving the practicality of the device.
