Description

Technical Field

[0001] The present invention relates to the field of pressure vessels, in particular to a reaction pressure vessel with high pressure resistance. Background Art

[0002] Reaction pressure vessels are pressure-bearing equipment used to achieve chemical reactions. Their basic characteristics include: they need to withstand harsh working conditions such as high pressure generated by internal medium reactions, medium corrosion, and temperature fluctuations. Structurally, they are mostly composed of a cylinder, a head, a connecting pipe, etc., and have high requirements for sealing reliability and fatigue resistance. Their typical application scenarios cover chemical synthesis, petroleum processing, pharmaceutical engineering and other fields.

[0003] After searching, the existing patent (publication number: CN109833827A) discloses an improved reaction pressure vessel, including a pressure vessel barrel, a head, a head reinforcement ring, a base, and a rotating device. Heads are provided at both ends of the pressure vessel barrel, and a head reinforcement ring is provided at the connection between the head and the pressure vessel barrel. The head reinforcement ring is provided with a front head reinforcement ring and a rear head reinforcement ring. The front head reinforcement ring extends outward along the axial direction of the pressure vessel barrel. This patent sets reinforcement rings on the front and rear heads to rigidly reinforce the joint between the barrel and the head, enhance the local bearing capacity, and has a reasonable structural design.

[0004] However, only rigidity enhancement is achieved through the reinforcement ring, but the pressure cannot be guided and the dynamic load cannot be actively dispersed, which leads to a shortened fatigue life of the equipment. Therefore, those skilled in the art have provided a reaction pressure vessel with high pressure resistance to solve the problems raised in the above background technology. Summary of the Invention

[0005] 1. Technical problems solved In view of the deficiencies of the prior art, the present invention provides a reaction pressure vessel with high pressure resistance, which solves the problem of being unable to guide the pressure.

[0006] 2. Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: A reaction pressure vessel with high pressure resistance comprises two sets of vertical plates, a tank body, a reinforcement mechanism, two sets of sealing structures, and two sets of fastening plates. The tops of the two sets of vertical plates are arc-shaped. The two sets of fastening plates are respectively arranged at both ends of the tank body. The two sets of fastening plates are respectively arranged on the tops of the two sets of vertical plates. The reinforcement mechanism is arranged on the surface of the tank body. Guide plates are arranged near both ends of the tank body. An arc-shaped reinforcement plate is arranged on the outer surface of the tank body at a position where the guide plates on the inner wall of the tank body are adapted. Through the above technical solution, the guide plate inside the tank body and the external arc-shaped reinforcement plate form an internal and external collaborative load-bearing structure. The guide groove transmits the stress in the high-pressure area in the center of the guide plate to the arc-shaped reinforcement plate on the surface of the tank body along a radial path. The arc-shaped reinforcement plate simultaneously strengthens the rigidity of the corresponding part, disperses the local stress, and avoids deformation and rupture caused by pressure concentration.

[0010] Furthermore, the surfaces of the two groups of guide plates are provided with multiple groups of guide grooves, and the guide grooves are radially shaped, and the widths of the two groups of guide grooves are gradually changing. Through the above technical solution, the guide groove is radial and has a gradually changing width, forming a structure with a narrow center and wide edges, which can gradually disperse the stress as it is transmitted along the groove, avoiding secondary concentration on the guide path. The guide groove provides an additional channel for the flow of the medium.

Obviously, the specific embodiments described are only part of the specific embodiments of the present invention, rather than all the specific embodiments.

The outer surface of the tank body 2 is adapted to the guide plate 17 on the inner wall of the tank body 2. An arc-shaped reinforcement plate 3 is provided. The guide plate 17 in the tank body 2 and the external arc-shaped reinforcement plate 3 form an internal and external coordinated load-bearing structure. The guide groove 18 transmits the stress of the high-pressure area in the center of the guide plate 17 to the arc-shaped reinforcement plate 3 on the surface of the tank body 2 along a radial path. The arc-shaped reinforcement plate 3 simultaneously strengthens the rigidity of the corresponding part, disperses the local stress, and avoids deformation and rupture caused by pressure concentration.

[0021] according to Figure 1 、 Figure 5 and Figure 4The reinforcement mechanism 4 includes multiple groups of first reinforcement hoops 401 and multiple groups of second reinforcement hoops 404. The lower parts of the multiple groups of first reinforcement hoops 401 and the multiple groups of second reinforcement hoops 404 are respectively connected by hinges. The multiple groups of first reinforcement hoops 401 and the multiple groups of second reinforcement hoops 404 are fixedly connected by connecting frames 402. The upper parts of the multiple groups of first reinforcement hoops 401 and the multiple groups of second reinforcement hoops 404 are respectively fixedly installed by studs 403. The surfaces of the multiple groups of studs 403 are threadedly connected with nuts 405. The two groups of sealing structures 8 include two groups of flanges 801. The surfaces of the two groups of flanges 801 are provided with multiple groups of tapered thread grooves 803. The multiple groups of tapered thread grooves 803 are threaded with tapered thread rods 802. Sealing plates 804 are arranged in the two groups of flanges 801. The surface of the tank body 2 is provided with two groups of pipe nozzles 6. The surfaces of the two groups of pipe nozzles 6 are provided with pressure-resistant plates 5. The two groups of sealing structures 8 are respectively arranged on the tops of the two groups of pipe nozzles 6. 405 , the first and second reinforcing hoops 401 and 404 are fixed to the surface of the tank body 2, and the surface of the tank body 2 is clamped to increase the pressure resistance of the surface of the tank body 2. Through the cooperation of the tapered threaded rod 802 and the tapered threaded groove 803, the higher the medium pressure, the tighter the thread teeth fit, and the sealing pressure ratio increases linearly with the pressure. With the cooperation of the sealing plate 804 and the flange 801, the sealing performance of the sealing structure 8 can be significantly improved. With the help of the pressure-resistant plate 5 and the guide rib 7 at the pipe mouth 6, the stress concentration caused by the opening is transmitted to the reinforcement mechanism 4 through the guide rib 7, so that the concentrated stress at the pipe mouth 6 is dispersed, thereby achieving the effect of pressure guidance and increasing the pressure resistance at the pipe mouth 6.

[0022] according to Figure 1 and Figure 2, the surfaces of the two groups of guide plates 17 are provided with multiple groups of guide grooves 18, and the guide grooves 18 are radially shaped, and the width of the two groups of guide grooves 18 is a gradual structure. The tops of the two groups of vertical plates 1 are provided with arc grooves 11, and the surfaces of the two groups of fastening plates 9 are provided with arc plates 10. The two groups of arc plates 10 are respectively slidably connected in the two groups of arc grooves 11. Both sides of the two groups of vertical plates 1 are provided with card slots 12. Both sides of the two groups of vertical plates 1 are movably connected with support plates 13 through pins. The bottoms of the two groups of support plates 13 are provided with bottom plates 15, and the tops of the two groups of bottom plates 15 are provided with threaded holes 14. The other side of the two groups of guide plates 17 is provided with multiple groups of damping shock absorbers 16, and the other end of the multiple groups of damping shock absorbers 16 is provided on one side of the fastening plate 9. The guide grooves 18 are radial and have a gradual width, forming a structure with a narrow center and a wide edge, which can gradually disperse the stress when it is conducted along the groove, avoiding two The secondary concentration, the guide groove 18 provides an additional channel for the flow of the medium. Under high pressure, part of the fluid is diverted through the groove body to reduce the solid bearing load of the guide plate 17. The sliding design of the arc plate 10 in the arc groove 11 allows the tank body 2 to generate adaptive displacement between the vertical plate 1 and the fastening plate 9 when the tank body 2 shakes due to pressure or other reasons, thereby avoiding stress concentration caused by rigid connection and improving structural fault tolerance. With the help of the card slot 12, the support plate 13 can be folded in the card slot 12 for easy storage. When the supporting device is in place, the base is in contact with the ground, and the support rod is fixed to the base through the threaded block to form a triangular support structure to improve the stability of the device. The damping shock absorber 16 connects the guide plate 17 and the fastening plate 9. When the internal pressure suddenly changes, the impact energy is absorbed through elastic deformation and damping dissipation. The damping shock absorber 16 can suppress material fatigue caused by high-frequency pressure fluctuations. Working principle: Fix two sets of vertical plates 1 to the ground according to the designed position, with the arc groove 11 on the top of the vertical plate 1 facing upward, and anchor it with expansion bolts through the threaded holes 14 of the bottom plate 15. Lift the tank body 2 so that the arc plates 10 of the fastening plates 9 at both ends slide into the arc groove 11 of the vertical plate 1. Then install the reinforcement mechanism 4 on the surface of the tank body 2, fit the first reinforcement hoop 401 and the second reinforcement hoop 404 to the tank body 2 through hinges, and connect them flexibly with the lower hinge. Tighten and fix the upper part with studs 403 and nuts 405. Tighten the studs 403 to improve the surface rigidity of the tank body 2. Install the pressure-resistant plate 5 at the pipe mouth 6 to cover the edge of the opening, and weld one end of the guide rib 7 to the pressure-resistant plate 5. The other end is fixed to the reinforcement mechanism 4 to form a stress diversion path. The flange 801 is installed on the top of the pipe mouth 6 and is tightened with the tapered threaded rod 802 and the tapered threaded groove 803 to make the sealing plate 804 close to the pipe mouth 6. The medium pressure is used to achieve self-tightening sealing. After the medium is injected into the tank body 2, the internal pressure is dispersed to the edge through the radial gradient guide groove 18 on the surface of the guide plate 17 to prevent the pressure from being concentrated in the center of the guide plate 17. The external arc-shaped reinforcement plate 3 simultaneously bears the stress. When the pressure fluctuates, the damping shock absorber 16 on the other side of the guide plate absorbs energy through elastic deformation and attenuates the pressure peak. The above can improve the pressure resistance of the reaction pressure vessel.
