[0026] The following will combine the embodiments of the utility model and the drawings of the specification to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the description of the present invention, it should be understood that the terms "center", "vertical", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0028] Post-processing and purification equipment for Fischer-Tropsch synthesis products, such as Figure 1-Figure 3As shown, it includes a purification extraction box 10 for post-treatment of Fischer-Tropsch synthesis products, and the purification extraction box 10 has an extraction mechanism 30 built in it; the extraction mechanism 30 includes a vertically arranged hollow liquid inlet column 31 and a plurality of groups of hollow liquid separation plates 32 connected to the outer wall of the hollow liquid inlet column 31, and the top surface of each group of hollow liquid separation plates 32 is provided with a plurality of liquid outlet holes 33 arranged evenly and equidistantly, and the top of the hollow liquid inlet column 31 is connected to a liquid inlet pipe 34, and each liquid outlet hole 33 is installed with a non-return nozzle 35, and the non-return nozzle 35 is installed with a socket 36 that is compatible with the size of the liquid outlet hole 33 and is plugged in and matched, and the end of each group of hollow liquid separation plates 32 is connected to the middle wall through a plug pipe 39. The inside of the empty liquid inlet column 31 is connected. By setting a hollow liquid separation plate 32 and opening a plurality of evenly and equidistantly arranged liquid outlet holes 33 on its top surface, uniform distribution of the raw liquid is achieved. A non-return nozzle 35 is installed on each liquid outlet hole 33 to ensure that the liquid can be sprayed out of the hole only under a specific pressure, further ensuring the uniform distribution and flow state of the liquid, improving the dispersion of the raw liquid and the contact area with the extractant, thereby improving the extraction efficiency and effect. The socket 36 installed on the non-return nozzle 35 is adapted to the size of the liquid outlet hole 33 and is plug-in compatible, which facilitates the replacement and maintenance of the non-return nozzle and improves the maintainability and service life of the equipment.

[0029] Furthermore, moving wheels 11 are installed at the four top corners of the bottom of the purification extraction box 10, and a push frame 12 with a U-shaped cross section is installed on the top outer wall of one end of the purification extraction box 10, so that the entire purification equipment is easy to move and transfer, and the flexibility and convenience of the equipment are improved. Whether on the production line or in the laboratory, the equipment can be easily moved to the required position, greatly improving work efficiency.

[0030] Specifically, a top cover 20 is provided on the top of the purification and extraction box 10. A socket that matches the size of the liquid inlet pipe 34 and is plugged in is provided on the top cover 20. Lifting rings 21 are symmetrically provided at both ends of the top surface of the top cover 20. The design of the top cover 20 can ensure that the purification and extraction box 10 remains closed during operation to prevent the spillage of the raw material liquid or the entry of impurities. The provision of the lifting ring 21 facilitates the opening and closing of the top cover 20, making the operation of the device more convenient.

[0031] Among them, a support seat 37 is installed at one end of the hollow liquid separation plate 32 away from the hollow liquid inlet column 31, and connecting ring seats 310 are symmetrically arranged at both ends of the hollow liquid separation plate 32. The connecting ring seats 310 are connected to the outer walls of the hollow liquid inlet column 31 and the support seat 37 by fixing bolts, thereby enhancing the structural stability of the hollow liquid separation plate 32 and making it difficult to deform or shift during use. At the same time, the connection method of the fixing bolts also facilitates the disassembly and replacement of the hollow liquid separation plate 32, thereby improving the maintainability of the equipment.

[0032] In addition, a connecting slot 38 that matches the size of the plug-in tube 39 and is plugged in and matched with the hollow liquid separation plate 32 is opened on the outer wall of the hollow liquid separation plate 32, so that the connection between the plug-in tube 39 and the hollow liquid separation plate 32 is tighter and more stable, avoiding leakage of liquid during transmission.

[0033] The working principle of the post-processing purification equipment for Fischer-Tropsch synthesis products is as follows: an extractant is added to the purification extraction box 10, and the raw liquid of the Fischer-Tropsch synthesis product is input into the hollow liquid inlet column 31 through the liquid inlet pipe 34. After the raw liquid accumulates to a certain amount in the hollow liquid inlet column 31, it begins to flow to each hollow liquid separation plate 32 through the plug-in pipe 39. The raw liquid is evenly distributed in the hollow liquid separation plate 32 and then flows out through the liquid outlet hole 33. Since a check nozzle 35 is installed on the liquid outlet hole 33, the liquid can be sprayed out from the hole only after reaching a specific pressure, thereby ensuring the uniformity of the liquid distribution and the flow state, so that the extractant in the extraction box 10 is in full contact with the raw liquid sprayed from the check nozzle 35.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
