[0002] Fischer-Tropsch wax is extracted from a plant that is common in some Southeast Asian countries. The source of Fischer-Tropsch wax is mainly the wax in its fruit or seeds. There are many methods to extract Fischer-Tropsch wax, the most common of which is the solvent method. First, the raw material is crushed and added to the solvent, and then the wax is extracted from the solvent through stirring, distillation, separation and other steps. The extracted Fischer-Tropsch wax needs to be further refined to remove impurities and improve quality. The production process of Fischer-Tropsch wax mainly includes the following steps: raw material preparation, cracking, dewaxing, washing, filtering, polymerization, catalyst removal, solidification and encapsulation.

[0003] At present, washing is to wash the wax hydrocarbons after dewaxing to remove impurities and impurities therein. Washing generally adopts solvent washing to fully mix the wax hydrocarbons and the solvent and separate them so that the solvent takes away the impurities therein. In order to ensure that the solvent and the wax hydrocarbons are fully mixed during use, a stirring component is usually set to stir the solvent and the wax hydrocarbons to speed up the mixing efficiency. The stirring rod will come into contact with the solvent. After use, the surface of the stirring rod needs to be cleaned. The stirring rod is located inside the box, which is not convenient for thorough cleaning and inconvenient to use. Based on this, a Fischer-Tropsch wax purification device that solves the above problems is proposed. Utility Model Content

The addition pipe 1 4 is used to add wax hydrocarbons, and the addition pipe 2 5 is used to add solvents. A pneumatic stirring assembly is installed inside the mixing box 1, and the pneumatic stirring assembly is used to accelerate the mixing of the solvent and wax hydrocarbons. A control valve 7 is installed on the surface of the connecting pipe 2, and the control valve 7 is used to control The connecting pipe 2 is on and off, and a filter frame 8 is slidably installed inside the filter box 3 below the connecting pipe 2. A filter screen 9 is installed at the bottom of the filter frame 8. The filter screen 9 is used to filter the washed wax hydrocarbons. An exhaust pipe 10 is installed at one end of the filter box 3 below the filter screen 9, and an exhaust fan 11 is installed at one end of the exhaust pipe 10. An air inlet 12 is arranged at the other end of the filter box 3. The air of the filter box 3 is extracted by using the exhaust fan 11, so that the air flow rate below the filter screen 9 is greater than the air flow rate above the filter screen 9, and the pressure below the filter screen 9 is less than the pressure above the filter screen 9, which effectively speeds up the filtration efficiency of the washed wax hydrocarbons. A discharge pipe 13 is installed at the bottom of the filter box 3, and the discharge pipe 13 is used to discharge the filtered wax hydrocarbons.

[0021] Specifically, the pneumatic stirring assembly includes a pneumatic device 601, a vent pipe 602, a diffuser plate 603 and a branch pipe 604. The pneumatic device 601 is installed on the upper end of the filter box 3, and the vent pipe 602 is installed on the output end of the pneumatic device 601. One end of the vent pipe 602 extends to the inside of the mixing box 1, and a plurality of diffusers 603 are installed on one end of the vent pipe 602. The interiors of the diffusers 603 are all connected through pipelines. The upper ends of the diffusers 603 are all installed with a plurality of branch pipes 604. The gas is discharged into the diffuser plate 603 through the vent pipe 602 through the pneumatic device 601, and discharged from the branch pipe 604 on the diffuser plate 603. Bubbles rise from the bottom of the solvent and wax hydrocarbon mixture. The purpose of stirring is achieved in the process of rapid rising and bursting of the bubbles, thereby achieving stirring of the solvent and wax hydrocarbons, and facilitating the full mixing of the solvent and wax hydrocarbons.

[0022] Furthermore, a one-way valve 14 is installed on the ventilation pipe 602 . The one-way valve 14 has one-way conductivity to facilitate the passage of gas.

The solvent and wax hydrocarbons enter the interior of the mixing box 1. At the same time, the pneumatic device 601 discharges the gas into the interior of the diffuser 603 through the vent pipe 602, and discharges it from the branch pipe 604 on the diffuser 603. The bubbles rise from the bottom of the solvent and wax hydrocarbon mixture to achieve stirring of the solvent and wax hydrocarbons, so that the wax hydrocarbons and the solvent are fully mixed and separated, so that the solvent takes away the impurities therein. The washed wax hydrocarbons enter the filter screen 9 inside the filter box 3 through the connecting pipe 2 for filtration. In this process, the exhaust fan 11 is used to extract the air from the filter box 3, so that the air flow rate below the filter screen 9 is greater than the air flow rate above the filter screen 9, and the pressure below the filter screen 9 is less than the pressure above the filter screen 9, which effectively accelerates the filtration efficiency of the washed wax hydrocarbons. The filtered wax hydrocarbons are discharged through the discharge pipe 13, which effectively increases the purity of the Fischer-Tropsch wax.
