Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically to a radiant section furnace tube with anti-deformation reinforcement. Background Technology

[0002] The radiant section furnace tube mainly absorbs the radiant heat generated by fuel combustion and transfers the heat to the material inside the tube, bringing it to the temperature required for the process to carry out chemical reactions such as cracking and conversion. In this process, the material inside the furnace tube undergoes physical or chemical changes under high temperature, and the furnace tube plays an important role in containing the material and transferring heat.

[0003] When the radiant section furnace tube is under heating, it will deform over a long period of use. This deformation will damage the structural integrity of the furnace tube and cause local stress concentration. These deformations will cause the stress distribution inside the furnace tube material to become unbalanced, and the stress in weak parts will increase sharply. If it is in this state for a long time, the furnace tube may develop cracks due to fatigue, and in severe cases, it may even rupture, causing material leakage inside the tube. Utility Model Content

[0004] The purpose of this invention is to provide a radiant furnace tube with anti-deformation reinforcement to solve the problem of deformation of radiant furnace tubes after long-term use as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a radiant section furnace tube with anti-deformation reinforcement, including a sealing assembly plate, wherein a liquid reaction tube is welded and fixedly installed on the inner side of the sealing assembly plate, and the liquid reaction tube forms a channel for liquid movement on the sealing assembly plate.

[0006] The liquid reaction tube is movably fitted with a movable support buckle, which applies a vertical support force to the liquid reaction tube. A central support frame is provided inside the movable support buckle for support.

[0007] Both sides of the movable support buckle are provided with side fixing plates. The inner side of the sealing assembly plate is welded and fixedly installed with fixing screws. The fixing screws pass through the side fixing plates and are threaded with first fixing bolts located on both sides of the side fixing plates.

[0008] Preferably, the sealing assembly plate has a liquid inlet and a liquid outlet at the installation position corresponding to the liquid reaction tube.

[0009] Preferably, the central support frame has an X-shaped cross-section, and the central support frame is supported at the corner position of the inner wall of the movable support buckle.

[0010] Preferably, the fixing screws are arranged in pairs, and the fixing screws are located between the horizontal portions of the liquid reaction tube.

[0011] Preferably, the slot on the side fixing plate and the fixing screw are in clearance fit.

[0012] Preferably, the ends of the plurality of fixing screws are connected by a limiting end plate, and the fixing screws are also threaded with a second fixing bolt, which is disposed on both sides of the limiting end plate and fits against the outer wall of the limiting end plate.

[0013] Preferably, the limiting end plate and the second fixing bolt form a limiting structure for the movement of the movable support buckle.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Generally, movable support clips are placed at the junction of the horizontal and vertical directions of the liquid reaction tube to ensure its overall strength and prevent deformation. Simultaneously, the movable support clips can also be installed at the deformation location to prevent further deformation. Supporting at the junction directly enhances the structural strength of this weak point, reducing the likelihood of deformation from the outset. This avoids safety hazards such as rupture and leakage due to excessive deformation of the reaction tube, ensuring the overall safety of the reaction system. Through targeted support, it effectively counteracts the additional stress on the deformed area, preventing further deformation and avoiding small deformations from developing into serious damage. This extends the service life of the reaction tube and reduces downtime and maintenance costs due to equipment failure. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a deformation-resistant and reinforced radiant furnace tube, which mainly includes a sealing assembly plate 1, a liquid reaction tube 2, a movable support buckle 3, a central support frame 4, a side fixing plate 5, a fixing screw 6, a first fixing bolt 7, a limiting end plate 8, and a second fixing bolt 9. The sealing assembly plate 1 serves as the basic load-bearing component, the liquid reaction tube 2 serves as the core of medium flow, the movable support buckle 3 serves as the deformation-resistant adjustment structure, and the remaining components cooperate to achieve the support and fixing functions. All components work together to form a complete deformation-resistant and reinforced system.

[0024] The overall structure has a clear division of labor, and the components work together to ensure the normal operation of the liquid reaction tube, while the targeted support design enhances the resistance to deformation, making it suitable for complex working conditions.

[0025] The sealing assembly plate 1 is made of high-temperature resistant alloy material. The liquid reaction tube 2 is fixedly installed on its inner side by welding process. The liquid reaction tube 2 is a hollow tubular structure and is made of corrosion-resistant and high-temperature resistant alloy material. The tube body forms a closed liquid flow channel on the sealing assembly plate 1. At the same time, the sealing assembly plate 1 has liquid inlet and liquid outlet corresponding to the inlet and outlet positions of the liquid reaction tube 2, respectively, for external pipeline to realize the input and output of liquid.

[0026] The welding fixing method ensures a firm connection between the liquid reaction tube and the sealing assembly plate, reducing the risk of loosening; the closed channel design ensures stable liquid flow in high-temperature environments, and the setting of liquid inlet and outlet facilitates system integration and improves equipment practicality.

[0027] The movable support buckle 3 is an 8-shaped structure adapted to the shape of the liquid reaction tube 2. It is movably sleeved on the outside of the liquid reaction tube 2 and can move along the tube's axial direction. A central support frame 4 is fixedly installed inside it. The cross-section of the central support frame 4 is X-shaped, and its four ends are welded and fixed to the corner positions of the inner wall of the movable support buckle 3 to form a stable support frame. When the movable support buckle 3 is sleeved on the liquid reaction tube 2, the central support frame 4 is in contact with the outer wall of the liquid reaction tube 2. The X-shaped structure distributes the support force to the tube body, mainly applying vertical support force to the liquid reaction tube 2.

[0028] The X-shaped central support frame effectively enhances the structural strength of the movable support buckle, while uniformly transmitting the support force to the liquid reaction tube, avoiding local stress concentration, improving the anti-deformation effect, and the movable sleeve design allows the support position to be flexibly adjusted to adapt to different deformation requirements.

[0029] The movable support buckle 3 has symmetrically welded side fixing plates 5 on both sides. The side fixing plates 5 have circular slots adapted to the fixing screws 6. The fixing screws 6 are threaded metal rods, welded in pairs to the inner side of the sealing assembly plate 1, and located between the horizontal sections of the liquid reaction tube 2, with their axis parallel to the horizontal section of the liquid reaction tube 2. The fixing screws 6 pass through the slots of the side fixing plates 5, and the two are in clearance fit (0.5-1mm), allowing the side fixing plates 5 to slide freely along the fixing screws 6, thereby adjusting the position of the movable support buckle 3. Two first fixing bolts 7 are also threaded onto the fixing screws 6, located on both sides of the side fixing plates 5. Once the position of the movable support buckle 3 is determined, tightening the first fixing bolts 7 on both sides clamps the side fixing plates 5, thus fixing their position.

[0030] The clearance fit design ensures that the movable support buckle can be flexibly adjusted to provide precise support according to the deformation of the liquid reaction tube; the clamping and fixing method of the first fixing bolt 7 is simple to operate and can stably lock the support position to prevent loosening during operation.

[0031] Before the equipment is put into operation, the movable support buckle 3 can be pre-adjusted to the intersection of the horizontal and vertical directions of the liquid reaction tube 2 (stress concentration area) and fixed by the first fixing bolt 7 to achieve preventive support. If the liquid reaction tube 2 undergoes local deformation during operation, the first fixing bolt 7 can be loosened, the movable support buckle 3 can be moved along the fixing screw 6 to the deformation position, and the bolt can be tightened again to prevent the deformation from expanding further. The limiting end plate 8 always restricts the movement range of the support buckle to ensure that it works within the effective support range.

[0032] It combines preventative support and targeted remedial functions, dynamically adapting to the deformation changes of liquid reaction tubes, significantly improving the equipment's resistance to deformation and service life, and reducing maintenance costs.

[0033] Working principle:

[0034] The movable support buckle 3 is installed on the liquid reaction tube 2. The position of the movable support buckle 3 is adjusted according to the need to support the liquid reaction tube 2. Generally, the movable support buckle 3 is supported at the junction of the horizontal and vertical directions of the liquid reaction tube 2 to ensure the overall strength of the liquid reaction tube 2 and prevent deformation of the liquid reaction tube 2. At the same time, the movable support buckle 3 can also be installed at the position where deformation occurs to support the liquid reaction tube 2 and prevent further deformation. During the adjustment of the position of the movable support buckle 3, the side fixing plate 5 will move on the fixing screw 6. After moving to the appropriate position, the side fixing plate 5 is fixed by rotating the first fixing bolt 7. The structure composed of the limiting end plate 8 and the second fixing bolt 9 can limit the movement of the movable support buckle 3 and prevent the movable support buckle 3 from leaving the track.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
