[0028] Refer to Figure 2 and Figure 3, the connecting device 6 includes an arc plate 602. A semi-circular groove 601 is formed on one side of the reactor body 1.

When using the connecting device 6, slide the arc plate 602 into the semi-circular groove 601, and then set the semi-circular plate 603 on the surface of the reactor body 1. Reverse operation can expose the semi-circular groove 601, and then the coking particles generated at the bottom of the reactor body 1 can be cleaned through the semi-circular groove 601.

[0029] Refer to Figure 4, the limiting device 7 includes a first connecting ring 701 and a second connecting ring 702. Rectangular grooves 703 are evenly formed at the bottom of the first connecting ring 701. Rectangular plates 704 are slidably connected to the inner walls of the rectangular grooves 703. The bottoms of the rectangular plates 704 are fixedly connected to the tops of the second connecting ring 702. When using the limiting device 7, slide the rectangular plates 704 into the interior of the rectangular grooves 703, so that the first connecting ring 701 and the second connecting ring 702 can be connected together, which is convenient for subsequent welding, and then it is convenient to weld the first connecting ring 701 and the second connecting ring 702 together. A first semi-circular strip 705 is sleeved on the surface of the first connecting ring 701. A round rod 706 is fixedly connected to the inner wall of the first semi-circular strip 705.

[0030] Working principle: When using the reactor, the reactants obtained by mixing heavy oil slurry with catalyst and hydrogen enter the interior of the distributor 3 through the feed port 2, and then enter the bottom of the straight pipe section, so that hydrogen and slurry come into contact. Through the deflector 4, a directional internal circulation is formed inside the reactor, enabling hydrogen and slurry to react fully, and thus a hydrogenation reaction can be carried out well (the technology of the hydrogen slurry bed reactor is already very mature and will not be elaborated here). When using the connecting device 6, slide the arc plate 602 into the semi-circular groove 601, and then set the semi-circular plate 603 on the surface of the reactor body 1. Start the motor 610, and drive the threaded rod 611 to rotate through the motor 610. In this way, the threaded rod 611 can drive the moving plate 606 to slide on the inner wall of the connecting frame 609, and then slide the clamping plate 608 into the clamping groove 607, thus well restricting the arc plate 602 inside the semi-circular groove 601. Reverse operation can expose the semi-circular groove 601, and thus the coking particles generated at the bottom of the reactor body 1 can be cleaned through the semi-circular groove 601. This is more convenient for cleaning the coking particles on the inner wall bottom of the reactor body 1, and to a certain extent, it can avoid the influence of coking particles on the subsequent reaction. When using the limiting device 7, slide the rectangular plate 704 into the rectangular groove 703, and sleeve the first semi-circular strip 705 and the second semi-circular strip 707 on the first connecting ring 701 and the second connecting ring 702. Restrict the first semi-circular strip 705 and the second semi-circular strip 707 at the connection of the first connecting ring 701 and the second connecting ring 702 through the support plate 709. Insert the clamping rod 710 to the bottom of the first semi-circular strip 705 and the second semi-circular strip 707. In this way, the first semi-circular strip 705 and the second semi-circular strip 707 can be well restricted at the connection of the first connecting ring 701 and the second connecting ring 702. Furthermore, the first connecting ring 701 and the second connecting ring 702 can be well welded together through the welding groove 708. In this way, the first connecting ring 701 and the second connecting ring 702 can be connected together, which is convenient for subsequent welding, and thus it is convenient to weld the first connecting ring 701 and the second connecting ring 702 together.
