[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] As shown in the figure, a fixed-bed reactor for silicone includes a lower head 1, a lower cylinder 4, an upper cylinder 19, and an upper head 20 that are detachably connected in sequence. The lower head 1 is connected to flange one 2 through fasteners, and the upper head 20 is connected to flange three 7 through fasteners. The lower cylinder 4 is connected to flange one 2 and flange two 5. One end of the upper cylinder 19 is connected to flange three 7, and the other end is connected to flange two 5. The lower head 1, the lower cylinder 4, the upper cylinder 19, and the upper head 20 are detachably connected. When a problem occurs in a part of them, it can be directly replaced. When maintenance and cleaning are required, the above four parts can be disassembled and cleaned and maintained separately. Moreover, the replacement of the internal composite layer structure is more convenient. The composite layer structure includes an orifice plate 16, a grid plate 17, and a screen plate 18. A filter layer 22 is provided between the orifice plate 16, the grid plate 17, and the screen plate 18. The composite layer structure is provided in both the lower cylinder 4 and the upper cylinder 19 and is used to filter impurities in the medium. A feed port 15 is provided at the lower part of the lower head 1, and a distributor 14 is adhered to the feed port 15. The medium is input into the reactor from the feed port 15, and the distributor 14 distributes the medium evenly in the reactor. A drain port 3 and a first manhole 13 are provided on the side of the lower cylinder 4. The drain port 3 can discharge the excess liquid. A second manhole 12 and a vent port 11 are provided on the side of the upper cylinder 19. A temperature measuring port 8, a pressure measuring port 10, and a discharge port 9 are provided at the top of the upper head 20. Packing assemblies 21 are provided in both the lower cylinder 4 and the upper cylinder 19. During use, if the packing assemblies 21 need to be increased or decreased, operations can be carried out through the first manhole 13 and the second manhole 12, and the vent port 11 discharges the excess gas.

[0026] The medium enters the reactor from the feed port 15 through a hydraulic pump and is sequentially sprayed onto the orifice plate 16, the grid plate 17, and the screen plate 18 in the lower cylinder 4 through the distributor 14. A vacuum is drawn at the discharge port 9 of the reactor, and the medium flows upward due to the pressure difference inside and outside the reactor. After passing through the packing assemblies 21, it then passes through the grid plate 17, the screen plate 18, and the orifice plate 16 of the upper cylinder 19 and flows out from the discharge port 9 provided at the upper head 20. Among them, the excess gas passes through the vent port 11 provided in the upper cylinder 19, and the excess liquid is discharged through the drain port 3 provided in the lower cylinder 4. At the same time, the temperature measuring port 8 and the pressure measuring port 10 provided at the upper head 20 are used to monitor the internal working conditions of the reactor. Ear seats 6 are respectively fixedly provided on both sides of the upper cylinder 19 and / or the lower cylinder 4, making it more convenient to move the reactor.

[0027] When maintenance and cleaning are required, a part or the whole can be selected. Only the corresponding flange needs to be disassembled, and then reinstalled after the maintenance and cleaning are completed. It is also more convenient to replace the grid plate 17, the screen plate 18, or the orifice plate 16. The medium with a higher purity is obtained by setting the multi-layer composite layer structure.

[0028] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
