Description

Technical Field

[0001] The invention relates to the technical field of pressure vessels, and in particular to an annular tube nozzle with adjustable spraying direction suitable for use in a pressure vessel. Background Art

[0002] The spray cooling process is often accompanied by phase change, which brings about a large amount of latent heat and can improve the heat transfer efficiency to a certain extent. The application range of spray cooling heat transfer is very wide, such as nuclear power plant reactor cooling system, crude oil processing, seawater resource utilization, etc. In these applications, the equipment forms of spray cooling heat transfer include pressure vessels, distillation towers, drying towers and combustion equipment.

[0003] The spray direction has a great influence on the cooling rate, and the spray coverage area also determines the cooling position. However, the nozzles in the previous stage of the project could not meet the dynamic requirements of adjustable spray direction, resulting in a single cooling position and an unadjustable spray condensation area.

[0004] In summary, we proposed a ring-tube nozzle with adjustable injection direction suitable for pressure vessels to solve the technical problem of difficult adjustment of the cooling position. Summary of the invention

[0006] The embodiment of the present invention is achieved as follows:

[0007] A ring-tube nozzle with adjustable spray direction suitable for use in a pressure vessel comprises a support rod, a spray tube is sleeved on the support rod, and a plurality of sliding openings are opened on the inner ring side of the spray tube.

[0008] A spray ring is rotatably arranged at the sliding opening, any of the above-mentioned spray rings is provided with a spray opening, any of the above-mentioned 5 spray rings is hinged with an adjusting rod, any of the above-mentioned adjusting rod passes through the above-mentioned sliding opening and is hinged to the sliding mechanism, and the above-mentioned sliding mechanism is slidably arranged along the axial direction of the above-mentioned support rod.

[0009] This design allows the spray direction, which was originally only able to cool a single position, to be dynamically changed, so that the cooling position is no longer single, and personnel can dynamically adjust the cooling position according to actual needs.

[0010] The dynamic cooling position can be adjusted according to the sliding speed of the sliding mechanism, thereby realizing the change of the overall spray condensation area.

[0011] In some embodiments of the present invention, the support rod is a screw rod, the sliding mechanism includes a moving block sleeved on the screw rod, the adjusting rod is hinged to the moving block, a rotating member is rotatably provided at the free end of the moving block, the rotating member is connected to a rotating nut, and the rotating nut is slidably sleeved on the screw rod.

[0012] 5 This design is ingenious in structure, so that the support rod can not only fix the injection pipe but also cooperate with the up and down movement of the adjustment rod.

[0013] In some embodiments of the present invention, the rotating member and the rotating nut are integrally formed.

[0014] The integral molding of the rotating member and the rotating nut makes it easier to process the parts and components, and also makes the operation of the entire sliding mechanism more stable.

[0015] In some embodiments of the present invention, the injection pipe is an annular nozzle, and one end of the annular nozzle is a closed end.

[0016] The annular tube arrangement makes the force acting on the support rod uniform, so that the annular tube nozzle with adjustable spray direction in the embodiment of the invention can reduce the occurrence of deflection during installation and use.

The sliding mechanism drives one end of the adjusting rod to move up and down, and the adjusting rod is forced to move upward, so that the jet connected to the other end starts to rotate upward or downward as the adjusting rod slides up and down, thereby adjusting the circumferential position of the injection port at the injection tube, thereby obtaining different jet directions, realizing the change of the cooling position, meeting the dynamic requirements of the spray direction, and changing the spray condensation area.

[0030] Example

[0031] Please refer to Figure 1-Figure 3 The object of the present invention is to provide an annular tube nozzle with adjustable injection direction suitable for pressure vessels, which can meet the annular injection cooling and dust reduction requirements in the container, and at the same time, different jet directions can be obtained by adjusting the circumferential position of the injection port 5.

[0032] A ring-tube nozzle suitable for adjusting the injection direction in a pressure vessel comprises a support rod 1, the support rod 1 is sleeved with an injection tube 2, a plurality of sliding openings 3 are provided on the inner ring side of the injection tube 2, an injection ring 4 is rotatably provided at any of the sliding openings 3, any of the injection rings 4 is provided with an injection port 5, any of the injection rings 4 is hinged with an adjustment rod 6, any of the adjustment rods 6 passes through the sliding opening 3 and is hinged to a sliding mechanism 7, and the sliding mechanism 7 is slidably provided along the axial direction of the support rod 1.

[0033] Principle of the present invention: The spray direction has a great influence on the cooling rate, and the spray coverage area also determines the cooling position. However, the nozzle in the previous stage project is difficult to meet the dynamic requirements of adjustable spray direction, resulting in a single cooling position and the spray condensation area cannot be adjusted. In the embodiment of the present invention, a support rod 1 is used to connect and fix the position of the injection pipe 2, and a sliding mechanism 7 and an adjusting rod 6 are arranged on the support rod 1. The sliding mechanism 7 drives one end of the adjusting rod 6 to move up and down, and the adjusting rod 6 is forced to move upward, so that the jet connected at the other end starts to rotate upward or downward as the adjusting rod 6 slides up and down, thereby adjusting the circumferential position of the injection port 5 at the injection pipe 2, thereby obtaining different jet directions, realizing the change of the cooling position, meeting the dynamic requirements of the spray direction, and changing the spray condensation area.

[0034] The two ends of the injection ring 4 are sealed and rotatably connected to the injection pipe 2. When dynamic cooling is required, the sliding mechanism 7 is first started, and the sliding mechanism 7 moves upward in the axial direction of the support rod 1, driving the hinged adjustment rod 6 to move upward. At the same time, the injection ring 4 rotates upward, and the position of the injection port 5 on the injection pipe 2 begins to rotate upward along the circumference of the injection pipe 2. When the injection port 5 reaches the side of the sliding port 3, the sliding mechanism 7 begins to move downward in the axial direction of the support rod 1, and the adjustment rod 6 moves downward. At the same time, the injection ring 4 rotates in the opposite direction, and the position of the injection port 5 on the injection pipe 2 rotates in the opposite direction along the circumference of the injection pipe 2. The up and down reciprocating rotation of the injection port 5 is completed; this design method allows the spray direction that can only be cooled in a single position to be dynamically changed, so that the cooling position is no longer single, and personnel can dynamically adjust the cooling position according to actual needs, and can change the change speed of the dynamic cooling position according to the sliding speed of the sliding mechanism 7, thereby realizing the change of the overall spray condensation area. In addition, the shape of the injection pipe 2 can be set according to the shape of the container. For example, if it is a square container, the injection pipe 2 can be bent into a square and sleeved on the support rod 1.

[0035] In some embodiments of the present invention, the support rod 1 is a screw rod, the sliding mechanism 7 includes a moving block 8 sleeved on the screw rod, the adjusting rod 6 is hinged to the moving block 8, a rotating member 9 is rotatably provided at the free end of the moving block 8, the rotating member 9 is connected to a rotating nut 10, and the rotating nut 10 is slidably sleeved on the screw rod.

[0036] In the above embodiment, the moving block 8 is provided with a rotating groove, a rotating ring is provided on the inner side of the rotating member 9, the rotating ring is rotatably set in the rotating groove, a slot is provided on the rotating nut 10, and a block is provided on the rotating member 9. The slot and the block are movably cooperated to complete the connection between the rotating member 9 and the rotating nut 10; the rotating nut 10 rotates, driving the rotating member 9 to rotate upward, and the rotating ring set in the rotating groove pushes the moving block 8 upward, and the moving block 8 slides upward to drive the hinged adjusting rod 6 upward. When the rotating nut 10 changes the rotation direction, the rotating member rotates 9 downward, and the rotating ring pushes the moving block 8 downward. The moving block 8 slides downward, driving the hinged adjusting rod 6 downward; this design method has an ingenious structure, so that the support rod 1 can cooperate to complete the up and down movement of the adjusting rod 6 while playing the function of fixing the injection pipe 2.

[0037] In some embodiments of the present invention, the rotating member 9 and the rotating nut 10 are integrally formed.

[0038] In the above embodiment, the rotating member 9 and the rotating nut 10 are integrally formed, which makes it easier to process the parts and components, and also makes the operation of the entire sliding mechanism 7 more stable.

[0039] In some embodiments of the present invention, the injection pipe 2 is an annular nozzle, and one end of the annular nozzle is a closed end.

[0040] In the above embodiment, the setting of the annular tube type spray pipe 2 is suitable for a variety of working environments, and the annular tube setting makes the force acting on the support rod 1 uniform, so that the annular tube type spray pipe with adjustable spray direction in the embodiment of the invention can reduce the occurrence of the phenomenon of falling during installation and use.

[0041] In some embodiments of the present invention, a connecting member 11 is disposed on the ring side of the injection pipe 2 , and the rotating member 9 is connected to the connecting member 11 .

[0042] In the above embodiment, the connecting member 11 is connected to the injection pipe 2 by welding, and the connecting member 11 and the support rod 1 are also connected by welding. In addition, the rotating member 9 preferably uses a connecting rod 5; this design method plays a role in fixing and supporting the injection pipe 2.

[0043] In some embodiments of the present invention, there are multiple connecting members 11 .

[0044] In the above embodiment, a plurality of connection members 11 can better support the injection pipe 2, so that the position of the injection pipe 2 is more stable.

[0045] In some embodiments of the present invention, a shielding valve 0 is provided on each side of the plurality of injection ports 5 .

[0046] In the above embodiment, the valve is a pipeline accessory used to open and close the pipeline, control the flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. Personnel can control the number of enabled injection ports 5 by opening and closing the shielding valve according to actual needs, and the opening size of the shielding valve can be determined according to specific needs.

[0047] In summary, the present invention provides a ring-tube type spraying device suitable for adjusting the spraying direction in a pressure vessel.

[0048] The nozzle has at least the following beneficial effects: the spray direction has a great influence on the cooling rate, and the spray coverage area also determines the cooling position. However, the nozzles in the previous stage of the project could not meet the dynamic requirements of adjustable spray direction, resulting in a single cooling position and an uncontrolled spray condensation area.

[0049] Adjustment phenomenon; In the embodiment of the present invention, a support rod 1 is used to connect and fix the position of the injection pipe 2, and a sliding mechanism 7 and an adjusting rod 6 are arranged on the support rod 1. The sliding mechanism 7 drives one end of the adjusting rod 6 to move up and down, and the adjusting rod 6 is forced to move upward, so that the injection connected at the other end starts to rotate upward or downward as the adjusting rod 6 slides up and down, thereby adjusting the circumferential position of the injection port 5 at the injection pipe 2, thereby obtaining different jet directions, realizing the change of the cooling position, meeting the dynamic requirements of the spray direction, and changing the spray condensation area.

[0050] The two ends of the injection ring 4 are sealed and rotatably connected to the injection pipe 2. When dynamic cooling is required, the sliding mechanism 7 is first started, and the sliding mechanism 7 moves upward in the axial direction of the support rod 1, driving the hinged adjustment rod 6 to move upward. At the same time, the injection ring 4 rotates upward, and the position of the injection port 5 on the injection pipe 2 begins to rotate upward along the circumference of the injection pipe 2. When the injection port 5 reaches the side of the sliding port 3, the sliding mechanism 7 begins to move downward in the axial direction of the support rod 1, and the adjustment rod 6 moves downward. At the same time, the injection ring 4 rotates in the opposite direction, and the position of the injection port 5 on the injection pipe 2 rotates in the opposite direction along the circumference of the injection pipe 2. The up and down reciprocating rotation of the injection port 5 is completed; this design method allows the spray direction that can only be cooled in a single position to be dynamically changed, so that the cooling position is no longer single, and personnel can dynamically adjust the cooling position according to actual needs, and can change the change speed of the dynamic cooling position according to the sliding speed of the sliding mechanism 7, thereby realizing the speed change of the overall spray condensation area. In addition, the shape of the injection pipe 2 can be set according to the shape of the container. For example, if it is a square container, the injection pipe 2 can be bent into a square and sleeved on the support rod 1.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
