Description

Technical Field

[0001] The present invention relates to the technical field of petroleum production equipment and process, in particular to a medium distribution device. Background Art

[0002] All major oil production equipment is equipped with a large number of reactors, towers, storage tanks and other devices. These devices are equipped with medium inlets and medium outlets. In particular, the interior of the medium inlet is mostly open, resulting in the medium being transported in constantly impacting the walls or internal components of the above-mentioned devices due to the influence of pressure and fluctuations. Long-term repeated use causes the above-mentioned devices to be damaged. Moreover, the medium cannot be evenly distributed inside the above-mentioned devices, affecting their fluidization and circulation, resulting in low product yield or substandard products. In addition, the long-term impact and erosion of the above-mentioned devices by specific media in a high-pressure state will also cause the wall thickness of the above-mentioned devices to be continuously reduced or cracks to appear, ultimately leading to the premature scrapping of the oil production equipment or even safety accidents, resulting in large losses.

[0003] The media inlets of existing reactors, towers, storage tanks and other devices are mostly open. After the medium enters, it is directly ejected and impacted on the opposite wall under the action of pressure. Especially when the pressure of the medium fluctuates repeatedly, the opposite wall is always under a large fatigue load. Over time, serious fatigue cracks will appear, eventually leading to damage or even explosion. Of course, there are also some powder media with high hardness and high flow rate. Long-term erosion of the walls of the above-mentioned devices will rapidly wear the walls, and over time, problems such as perforation will occur. Summary of the Invention

[0004] The main purpose of the present invention is to provide a medium distribution device to solve the problem that the medium inlets of reactors, towers, storage tanks and other devices in the prior art are mostly open, resulting in long-term erosion of the walls of the above-mentioned devices by the medium, which will rapidly wear the walls and cause perforation over time.

[0013] Furthermore, the assembly hole is located at the bottom surface of the accommodating cavity, the branch pipe structure located at the head is vertically penetrated at the assembly hole, and at least one of the remaining branch pipe structures located in the accommodating cavity is extended in the horizontal direction.

[0014] Furthermore, in the direction from the head to the tail, at least the second branch pipe structure has a first pipe section, a transition pipe section, and a second pipe section that are connected to each other. The first end of the first pipe section of the second branch pipe structure is an open end, which is used to communicate with the connecting port of the first branch pipe structure. The end of the second pipe section of the second branch pipe structure away from the first pipe section is a closed end, and the cross-sectional area of ​​the flow surface of the first pipe section is greater than the cross-sectional area of ​​the flow surface of the second pipe section.

[0015] Furthermore, the transition pipe section is a tapered pipe section, and the large end side of the transition pipe section is used to connect with the second end of the first pipe section, and the small end side of the transition pipe section is used to connect with the end of the second pipe section away from the closed end.

[0016] Furthermore, the medium distribution device further includes a first obstacle, which is disposed in the accommodating cavity and is located on the injection path of the nozzle structure.

[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] In order to solve the problem that the medium inlets of reactors, towers, storage tanks and other devices in the prior art are mostly open, resulting in long-term erosion of the walls of the above devices by the medium, which will rapidly wear the walls and cause perforation over time, the present invention provides a medium distribution device.

[0033] like Figure 1 and Figure 2 As shown, the medium distribution device includes a shell 10 and a medium input assembly 20. The shell 10 has a receiving cavity 11 and an assembly hole 12 and a medium outlet connected to the receiving cavity 11; the medium input assembly 20 includes a plurality of branch pipe structures 21 connected in sequence, each branch pipe structure 21 has an open end and a closed end, and the pipe wall surface of each branch pipe structure 21 is provided with at least one communication port. Among two adjacent branch pipe structures 21, the communication port of the first branch pipe structure 21 is connected to the open end of the second branch pipe structure 21, and the branch pipe structure 21 located at the tail is connected to the open end of the second branch pipe structure 21. The communicating port is used to communicate with the nozzle structure 30; wherein, the branch pipe structure 21 located at the head is penetrated at the assembly hole 12, and the open end of the branch pipe structure 21 located at the head is located outside the accommodating cavity 11 to form a medium inlet 13 for communicating with the accommodating cavity 11, and the closed end of the branch pipe structure 21 located at the head is located within the accommodating cavity 11, and the communicating port of the branch pipe structure 21 located at the head is located within the accommodating cavity 11, for communicating with the open end of the first branch pipe structure 21 among the remaining branch pipe structures 21 located in the accommodating cavity 11.

[0034] By applying the technical solution of the present invention, a medium distribution device including a medium input component 20 is provided. The medium input component 20 is arranged into a structural form including multiple branch pipe structures 21 connected in sequence. At the same time, each branch pipe structure 21 has an open end and a closed end, and the pipe wall surface of each branch pipe structure 21 is provided with at least one connecting port. Among two adjacent branch pipe structures 21, the connecting port of the first branch pipe structure 21 is connected to the open end of the second branch pipe structure 21, and the connecting port of the branch pipe structure 21 located at the tail is used to connect with the nozzle structure 30.

[0035] Specifically, the branch pipe structure 21 at the head is passed through the assembly hole 12, and the open end of the branch pipe structure 21 at the head is located outside the accommodating cavity 11 to form a medium inlet 13 for communicating with the accommodating cavity 11, and the closed end of the branch pipe structure 21 at the head is located inside the accommodating cavity 11, and the communication port of the branch pipe structure 21 at the head is located inside the accommodating cavity 11, so as to be communicated with the open end of the first branch pipe structure 21 among the remaining branch pipe structures 21 located in the accommodating cavity 11. In this way, the medium inlet 13 is arranged outside the accommodating cavity 11 to ensure the convenience of medium input. At the same time, the branch pipe structure 21 at the head is located inside the accommodating cavity 11. The closed end of the branch pipe structure 21 is located within the accommodating chamber 11, so that when the medium enters the branch pipe structure 21 located at the head through the medium inlet 13, its closed end can play a role in preliminary buffering the impact of the medium. Similarly, the medium passes through each connecting port in sequence and the closed end of each subsequent branch pipe structure 21, which will gradually alleviate the impact of the medium. Finally, the medium is ejected through the nozzle structure 30 on the branch pipe structure 21 at the tail, further reducing the impact force of the medium, effectively alleviating the impact of the medium on the cavity wall of the accommodating chamber 11 of the medium distribution device, and ensuring the service life of the medium distribution device.

[0036] It should be noted that in the present application, the cross-sectional area of ​​the flow surface of each branch pipe structure 21 is gradually reduced from the head to the tail, so as to greatly reduce the impact force of the medium after it passes through each branch pipe structure 21 in sequence.

[0037] Optionally, the geometric centers of the branch pipe structures 21 extend in different directions, so as to ensure that the impact force of the medium can be reduced as much as possible after the medium passes through the branch pipe structures 21 with different extension directions in sequence.

[0038] It should be noted that in this application, Figure 1 and Figure 2 As shown, at least the branch pipe structure 21 at the rear portion has multiple communication ports, and there are multiple nozzle structures 30, each corresponding to the multiple communication ports. This way, as the medium flows through the branch pipe structure 21 at the rear portion, the pressure of the medium after being ejected through each nozzle structure 30 is minimized under the action of pressure.

[0039] It should be noted that in the present application, at least two of the multiple nozzle structures 30 have different spraying directions. This ensures that the medium ejected from each nozzle structure 30 can hit the cavity wall of the housing 10 as evenly as possible, thereby ensuring uniform distribution of the medium within the housing 11.

[0040] Optionally, the spraying direction of the nozzle structure 30 and the extension direction of the branch pipe structure 21 at the rear portion have a preset angle A. This ensures that the medium sprayed through the nozzle structure 30 does not adhere to the outer peripheral surface of the branch pipe structure 21 at the rear portion, and also ensures that the medium sprayed through the nozzle structure 30 is dispersed as much as possible.

[0041] It should be noted that, in the present application, the preset angle A satisfies: 0°≤A≤90°.

[0042] Preferably, the preset angle A satisfies: A=43.50°. This is conducive to accurately controlling the direction of the medium entering the accommodating chamber 11, thereby ensuring that the medium can be distributed as evenly as possible in every corner of the accommodating chamber 11.

[0043] like Figure 1 As shown, the assembly hole 12 is located at the bottom surface of the accommodating cavity 11, the branch pipe structure 21 located at the head is vertically penetrated at the assembly hole 12, and at least one of the remaining branch pipe structures 21 located in the accommodating cavity 11 is extended in the horizontal direction.

[0044] like Figure 1 As shown, in the direction from the head to the tail, at least the second branch pipe structure 21 comprises a first pipe section 211, a transition pipe section 212, and a second pipe section 213 that are connected. The first end of the first pipe section 211 of the second branch pipe structure 21 is open, for communicating with the communication port of the first branch pipe structure 21. The end of the second pipe section 213 of the second branch pipe structure 21, which is remote from the first pipe section 211, is closed. The cross-sectional area of ​​the flow surface of the first pipe section 211 is larger than the cross-sectional area of ​​the flow surface of the second pipe section 213. Thus, by having at least the second branch pipe structure 21 comprise a first pipe section 211, a transition pipe section 212, and a second pipe section 213 that are connected, and the cross-sectional area of ​​the flow surface of the first pipe section 211 being larger than the cross-sectional area of ​​the flow surface of the second pipe section 213, the impact force of the medium is effectively reduced.

[0045] Furthermore, the transition pipe section 212 is a tapered pipe section, with the large end of the transition pipe section 212 being connected to the second end of the first pipe section 211, and the small end of the transition pipe section 212 being connected to the end of the second pipe section 213 away from the closed end. This ensures the reliability and sealing of the connection between the first pipe section 211, the transition pipe section 212, and the second pipe section 213.

[0046] like Figure 1 and Figure 2As shown, the medium distribution device further includes a first obstacle 40, which is disposed within the accommodating chamber 11 and is located on the spray path of the nozzle structure 30. Thus, the provision of the first obstacle 40 further mitigates the impact force of the medium, preventing the medium from directly hitting the wall of the accommodating chamber 11 and damaging the housing 10.

[0047] like Figure 1 and Figure 2 As shown, the first obstacle 40 is arranged at the geometric center of the bottom surface of the accommodating cavity 11 .

[0048] like Figure 1 As shown, the medium distribution device further includes a second obstacle 50, which is disposed within the accommodating chamber 11 and is located on the outer periphery of the first obstacle 40. Thus, the provision of the second obstacle 50 further enhances the mitigation of the impact force of the medium entering the accommodating chamber 11 from different directions, preventing the medium from directly striking the wall of the accommodating chamber 11 and damaging the housing 10.

[0049] like Figure 1 As shown, the line connecting the geometric center of the first obstacle 40 and the geometric center of the second obstacle 50 passes through the geometric center of the housing 10 .

[0050] like Figure 1 As shown, the cross-sectional area of ​​the first obstacle 40 is greater than the cross-sectional area of ​​the second obstacle 50 .

[0051] like Figure 1 and Figure 2 As shown, there are two groups of medium input components 20, and the two groups of medium input components 20 are respectively located on both sides of the line connecting the geometric center of the first obstacle 40 and the geometric center of the second obstacle 50. There are two assembly holes 12, and the two assembly holes 12 are respectively used to pass through the branch pipe structure 21 located at the head of the two groups of medium input components 20.

[0052] It should be noted that, in the present application, the medium distribution device also includes a support frame 60, the first end of the support frame 60 is used to connect to the cavity wall of the accommodating cavity 11, and the second end of the support frame 60 is connected to the second branch pipe structure 21 through a U-shaped card. The setting of the support frame 60 serves as a support point for each branch pipe structure 21 to prevent the branch pipe structure 21 from breaking due to shaking during the operation of the medium distribution device.
