DETAILED DESCRIPTION
[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0030] REFERENCE Figs. 1-3The utility model provides an embodiment: a condenser of shunt vibration reduction structure, including support 1, support 1 is as the basic support structure of condenser, its main function is the weight of supporting whole condenser, the top fixed connection of support 1 has cylinder 5, is seted up with passageway one 16 in cylinder 5 inside, is seted up with passageway two 17 in cylinder 5 inside, is seted up with passageway three 18 in cylinder 5 inside, through reasonable fluid distribution design, the medium in condenser can flow efficiently, and carry out effective heat exchange with heat exchange tube bundle 3, cylinder 5 inside is provided with a plurality of heat exchange tube bundle 3, heat exchange tube bundle 3 is regularly arranged, provides extensive surface area to improve heat exchange efficiency, cylinder 5 inside is provided with shunt vibration reduction subassembly, and cylinder 5 one end is provided with sealing assembly,

[0032] Specifically, the condenser is stably installed in the use area by two supports 1, ensuring that the equipment can remain stable during operation. The gas first enters the inside of the cylinder body 5 of the condenser through the gas inlet 8. After reasonable flow channel design, the gas flow is guided into the condensing area. In the design, the impact force and vibration that the large flow and large pressure gas flow may cause to the heat exchange tube bundle 3 are considered, and the upright split-flow damping fixed plate 7 and the inverted split-flow damping fixed plate 19 are specially arranged inside the cylinder body 5. These split-flow plates can evenly distribute the incoming gas flow into three directions, so that the gas flow can flow more smoothly through the heat exchange tube bundle 3, thereby improving the heat exchange efficiency and reducing the vibration of the tube bundle. The upright split-flow damping fixed plate 7 has a special arc-shaped design, which can effectively reduce the friction and impact of the gas flow when passing through each passage and the plate surface, thereby significantly reducing the vibration and noise brought by the gas flow. The center part of the split-flow plate is provided with a plurality of circular holes, and the angle between each circular hole is 60°. The layout of these circular holes helps to evenly distribute the gas flow and avoid concentrated impact of the gas flow, further optimizing the flowability of the gas flow. The upright split-flow damping fixed plate 7 is firmly connected with the inside of the cylinder body 5 by welding, to ensure that the plate part can still remain stable under the action of high-pressure gas flow. The heat exchange tube bundle 3 passes through the upright split-flow damping fixed plate 7 and is tightly fixed with the split-flow plate by welding, enhancing the overall strength and durability of the condenser. Especially when facing the impact of large flow and large pressure gas flow, it can effectively avoid the vibration and displacement of the tube bundle, thereby prolonging the service life of the equipment and reducing the maintenance cost. In addition, in order to further reduce the impact and vibration of the gas flow on the heat exchange tube bundle 3, the inverted split-flow damping fixed plate 19 cooperates with the upright split-flow damping fixed plate 7 to further split and dampen, ensuring that the gas flow can remain more stable when passing through the heat exchange tube bundle, maximizing the heat exchange efficiency. Not only does it improve the condensing effect, but it also effectively reduces the noise and vibration during operation, ensuring the long-term stable operation of the equipment.
[0033] Reference Figs. 1-3The sealing assembly comprises a sealing head 2 fixedly connected at one end of a cylinder 5, the right-angled split-flow damping fixed plate 7 and the inverted split-flow damping fixed plate 19 are both arc-shaped, the other end of the cylinder 5 is fixedly connected with a plate sealing head 13, a plurality of holes for mounting bolts 12 are arranged in the plate sealing head 13 to enhance the connection strength between the plate sealing head 13 and the cylinder 5, the plate sealing head 13 is internally provided with the bolts 12, the outer wall of the bolt 12 is threadedly connected with a nut 11, the plate sealing head 13 is fixedly connected with a flange 10, the flange 10 is connected with the bolt 12 through a fastener, and the stability and reliability of the connection are further improved, the cylinder 5 is internally provided with a cold water inlet 9, the cylinder 5 is internally provided with a cold water outlet 14, the cold water inlet 9 and the cold water outlet 14 are respectively used for controlling the inflow and outflow of the cooling liquid, the cylinder 5 is internally provided with an air inlet 8 and an air outlet 15, the air inlet 8 and the air outlet 15 are used for the inflow and outflow of the gas, the smooth flow of the air in the equipment and the effective regulation of the temperature are ensured, the cylinder 5 is internally provided with a relief port 6, in the case of overpressure or other abnormal conditions, the excess pressure or gas is released, the equipment is prevented from being damaged due to overload, and the cylinder 5 is fixedly connected with a lifting lug 4 on the outer wall, which is used for lifting operation during the carrying, installation and maintenance of the equipment.
[0034] Specifically, the inverted flow-dividing damping fixed plate 19 is welded and fixed with the cylinder 5 by changing the installation direction. This structure optimizes the flow direction of the gas flow. Although the direction of the gas flow channel is changed, the cross-sectional area of the gas flow remains unchanged, ensuring the smoothness and consistency of the gas flow, effectively and evenly distributing the gas in the shell side, reducing the dead angle and uneven flow of the gas flow, avoiding the phenomenon of gas flow concentrated in a certain area, thereby ensuring that the gas can fully contact the heat exchange tube bundle 3. In this way, the heat exchange efficiency of the condenser is significantly improved, and the heat exchange process can be completed more efficiently. In the heat exchange process of the condenser, the cold water flows into the heat exchange tube bundle 3 from the cold water inlet 9, and exchanges heat with the hot gas in the heat exchange tube bundle 3. In this process, heat is transferred from the gas to the cold water, and the cold water is heated and flows to the cold water outlet 14 at the bottom of the condenser to be discharged, thereby completing the cooling task. The flow design of the cold water in the tube bundle not only ensures the effective transfer of heat, but also avoids the problem of uneven water flow and reduced heat exchange efficiency by arranging the appropriate flow rate and flow direction. The condenser uses a fixed and welded sealing head 2 at one end and a plate sealing head 13 at the other end, which not only ensures the sealing and safety of the condenser in a high-pressure working environment, but also facilitates the manufacture and maintenance of the condenser. The cylinder 5 is tightly connected with the flange 10 through the bolt 12 and the nut 11, which ensures the firmness between the cylinder 5 and the components, and also facilitates the future disassembly, maintenance and replacement. To ensure that the condenser will not be dangerous due to excessive internal pressure during operation, the cylinder 5 is designed with a relief port 6. When the gas pressure in the condenser exceeds the set value, the relief port 6 can be quickly opened to discharge excess gas and reduce the pressure in the shell side, ensuring the safe operation of the equipment. In addition, the cylinder 5 is also provided with two lifting lugs 4 for easy loading and hoisting, which can ensure the balance and stability of the condenser during hoisting and reduce damage caused by uneven stress.
