[0022] This embodiment provides a fan-shaped tube reactor, such as Figures 1 to 5As shown, it includes: a riser 1; a blind section assembly, which is arranged at the end of the riser 1 and connected to the riser 1; a barrel section back plate 11, which is arranged at the end of the blind section assembly and connected to the blind section assembly; a first side plate, which is arranged on the first side of the barrel section back plate 11 and connected to the barrel section back plate 11; a second side plate, which is arranged on the second side of the barrel section back plate 11 and connected to the barrel section back plate 11, and the first side plate and the second side plate are arranged opposite to each other; an oblong hole sieve plate 8, which is arranged opposite to the barrel section back plate 11 and connected to both the first side plate and the second side plate, the barrel section back plate 11, the first side plate, the second side plate and the oblong hole sieve plate 8 enclose a barrel section 4, and the width of the oblong hole sieve plate 8 is smaller than the width between the first side plate and the second side plate.

[0023] The fan-shaped tube reactor in this embodiment limits the width of the oblong hole sieve plate 8 to be smaller than the width between the first side plate and the second side plate, so that the cross-section of the fan-shaped tube reactor is a "trapezoidal" structure. When multiple fan-shaped tube reactors are fixedly installed inside the reforming reactor, the inside of the fan-shaped tube reactor is filled with reactants. The side of the fan-shaped tube reactor provided with the oblong hole sieve plate 8 faces the catalyst. When the chemical reaction is intense, the impact of the catalyst on the fan-shaped tube reactor increases, and the width of the oblong hole sieve plate 8 is smaller than the width between the first side plate and the second side plate. The oblong hole sieve plate 8 arched in the direction toward the catalyst increases the mechanical strength, thereby improving the overall mechanical strength and service life of the fan-shaped tube reactor, and providing convenience for the installation or maintenance and overhaul of the fan-shaped tube reactor.

[0024] Exemplarily, the riser 1, the blind section assembly, the first side plate, the second side plate, the barrel section back plate 11 and the oblong hole sieve plate 8 are all fixedly connected by welding, thereby ensuring the overall strength of the sector-shaped barrel reactor.

[0025] Exemplarily, the sector-shaped tube reactor is vertically arranged inside the reforming reactor, and the riser 1 is located at the top. The riser 1 is cylindrical, and the area of ​​the circle per unit area is the largest. Therefore, setting the riser 1 to a cylindrical shape is beneficial to the input of reaction materials and the discharge of chemical gases generated during the chemical reaction.

[0026] In a possible embodiment, Figures 1 to 3 As shown, the blind section assembly includes: an upper blind section 2, which is arranged at the end of the riser 1 and connected to the riser 1; and a lower blind section 3, which is arranged at the end of the upper blind section 2 away from the riser 1 and connected to the upper blind section 2.

[0027] Exemplarily, the dimension of the end of the upper blind section 2 connected to the riser 1 is greater than the dimension of the end of the upper blind section 2 connected to the lower blind section 3, and the dimension of the lower blind section 3 is the same as the barrel section 4. This arrangement, on the one hand, ensures the connection between the upper blind section 2 and the riser 1, maximizes the area of ​​the riser 1, and facilitates the riser 1 to discharge the gas generated in the chemical reaction. On the other hand, it ensures the connection between the lower blind section 3 and the barrel section 4, thereby ensuring that the relative dimension of the barrel section 4 is smaller, and correspondingly increases the mechanical strength of the barrel section 4.

[0028] In a possible embodiment, Figures 1 to 3 As shown, the upper blind section 2 includes: a top plate 5, which is arranged at the end of the riser 1 and connected to the riser 1; an upper blind section back plate 9, which is arranged on the side of the top plate 5 away from the top plate 5 and connected to the top plate 5; an upper blind section cover plate 6, which is arranged opposite to the upper blind section back plate 9 and connected to the upper blind section back plate 9, and the top plate 5, the upper blind section back plate 9 and the upper blind section cover plate 6 enclose the upper blind section 2.

[0029] Exemplarily, the top plate 5 of the upper blind section 2 , the upper blind section back plate 9 and the upper blind section cover plate 6 are all fixedly connected by welding, thereby ensuring the overall mechanical strength of the upper blind section 2 .

[0030] In a possible embodiment, Figures 1 to 3 As shown, the lower blind section 3 includes: a lower blind section back plate 10, which is arranged between the upper blind section back plate 9 and the barrel section back plate 11, and is connected to both the upper blind section back plate 9 and the barrel section back plate 11; a lower blind section cover plate 7, which is arranged opposite to the lower blind section back plate 10 and is connected to the lower blind section back plate 10, and the lower blind section back plate 10 and the lower blind section cover plate 7 enclose the lower blind section 3.

[0031] Exemplarily, the lower blind section back plate 10 and the lower blind section cover plate 7 are fixedly connected by welding, thereby ensuring the overall mechanical strength of the upper blind section 2 .

[0032] Illustratively, the sector-shaped tube reactor in this embodiment is placed vertically in the reforming reactor, so that the thickness of the catalyst in each horizontal bed layer is consistent, which helps to evenly distribute the materials in the reforming reactor and improves the efficiency of catalyst use; there is no "dead zone" between the sector-shaped tube reactors, and there is no carbon accumulation, which reduces the agglomeration caused by high carbon deposition and coking of the catalyst, thereby ensuring the operating safety of the sector-shaped tube reactor.

[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
