Description

Technical Field

[0001] This utility model relates to the field of chemical machinery technology, and in particular to a condenser with a vibration reduction and noise reduction structure. Background Technology

[0002] Condensers are a common heat exchange device in factories. In shell-and-tube condensers, gas distributors and noise-reducing orifice plates are installed at the hot end inlet and outlet to change the airflow direction and reduce vibration and noise. Most shell-and-tube condensers sold on the market do not fully consider the impact of high pressure and large airflow on the tube side of the gas inside the shell. The high flow velocity will cause the airflow to deflect at the condenser inlet and inside, which will cause local vibration and generate gas noise. Moreover, the deflection will reduce the heat exchange efficiency and fail to achieve the ideal heat exchange effect.

[0003] In existing technologies, the heat exchange area of ​​the condenser is often calculated theoretically. However, in actual use, the noise from airflow and condenser impact that often occurs during condenser operation is usually reduced by adding a silencer to the condenser outlet pipe.

[0004] However, in the aforementioned existing technologies, the installation cost of silencers is relatively high, and they do not reduce noise and vibration by changing the frequency of airflow within the condenser at the sound source. Utility Model Content

[0005] The purpose of this invention is to provide a condenser with a vibration reduction and noise reduction structure, which aims to solve the technical problems of high installation cost of silencers in the prior art and the lack of a method to reduce noise and vibration by changing the frequency of airflow within the condenser at the sound source.

[0006] To achieve the above objectives, this utility model employs a condenser with a vibration reduction and noise reduction structure, comprising a condenser outer cylinder, an air inlet assembly, an air outlet assembly, a stabilizing assembly, and a cooling assembly. The cooling assembly is fixedly connected to the condenser outer cylinder and located on the inner wall of the condenser outer cylinder. The stabilizing assembly is fixedly connected to the condenser outer cylinder and located on the periphery of the condenser outer cylinder. The air outlet assembly is fixedly connected to the condenser outer cylinder and located below the condenser outer cylinder. The air inlet assembly is fixedly connected to the condenser outer cylinder and located above the condenser outer cylinder.

[0007] The condenser outer cylinder includes a cylinder body, an arc-shaped end cap, and a flange-type end cap. The flange-type end cap is fixedly connected to the cylinder body and located at one end of the cylinder body, while the arc-shaped end cap is fixedly connected to the cylinder body and located at the other end of the cylinder body.

[0008] The air intake assembly includes an air intake port, a quadrangular baffle, and multiple round steel bars. The lower end of each round steel bar is fixedly connected to the quadrangular baffle and is located above the quadrangular baffle. The upper end of each round steel bar is fixedly connected to the cylinder and is located on the inner wall of the cylinder. The air intake port is fixedly connected to the cylinder and is located above the cylinder.

[0009] The air outlet assembly includes an air outlet and a honeycomb noise reduction plate. The honeycomb noise reduction plate is fixedly connected to the air outlet and is located on the inner wall of the air outlet. The honeycomb noise reduction plate has multiple regular hexagonal holes.

[0010] The stabilizing component includes a lug and two saddles. Both saddles are fixedly connected to the cylinder and located below the cylinder. The lug is fixedly connected to the cylinder and located above the cylinder.

[0011] The cooling assembly includes a cooling water inlet, a cooling water outlet, a fixing plate, and multiple cooling water pipes. Each cooling water pipe is fixedly connected to the fixing plate and located inside the fixing plate. The fixing plate is fixedly connected to the cylinder and located on the inner wall of the cylinder. The cooling water outlet is fixedly connected to the cylinder and located below the cylinder. The cooling water inlet is fixedly connected to the cylinder and located above the cylinder.

[0012] This utility model discloses a condenser with a vibration reduction and noise reduction structure. Hot-end gas enters through the inlet, and the quadrangular baffles change the direction of the airflow while simultaneously distributing the gas evenly around its perimeter, effectively reducing the vertical impact vibration of the airflow on the cooling water pipes. After heat exchange through the cylinder and cooling water pipes, the hot-end gas finally exits the cylinder through the honeycomb noise reduction plate in the outlet and proceeds to the next process. The design of the honeycomb noise reduction plate in the outlet ensures that the exhaust airflow passes more evenly through each regular hexagonal hole, dividing the large airflow into several uniform small airflows exiting the cylinder. The area of ​​the regular hexagonal holes and the slightly... The cross-sectional area of ​​the air inlet pipe is slightly greater than or equal to ensure the throughput of the exhaust airflow.

The cooling water inlet and outlet facilitate the entry and exit of cold end water, ensuring the heat exchange efficiency of the cylinder. A discharge port is also provided on the top of the cylinder to prevent overpressure of the condenser and ensure the safety of the condenser during operation. The flange-type end cap design facilitates the maintenance of the cooling water pipe. The two saddle structures support the weight of the condenser.

Detailed Implementation

[0019] Please see Figures 1 to 4 This utility model provides a condenser with a vibration reduction and noise reduction structure, including a condenser outer cylinder 1, an air inlet assembly 2, an air outlet assembly 3, a stabilizing assembly 4, and a cooling assembly 5. The cooling assembly 5 is fixedly connected to the condenser outer cylinder 1 and is located on the inner wall of the condenser outer cylinder 1. The stabilizing assembly 4 is fixedly connected to the condenser outer cylinder 1 and is located on the periphery of the condenser outer cylinder 1. The air outlet assembly 3 is fixedly connected to the condenser outer cylinder 1 and is located below the condenser outer cylinder 1. The air inlet assembly 2 is fixedly connected to the condenser outer cylinder 1 and is located above the condenser outer cylinder 1.

[0020] Furthermore, the condenser outer cylinder 1 includes a cylinder body 6, an arc end cap 7, and a flange end cap 8. The flange end cap 8 is fixedly connected to the cylinder body 6 and located at one end of the cylinder body 6, while the arc end cap 7 is fixedly connected to the cylinder body 6 and located at the other end of the cylinder body 6.

[0021] Furthermore, the air intake assembly 2 includes an air intake 9, a quadrangular baffle 10, and multiple round steel bars 11. The lower end of each round steel bar 11 is fixedly connected to the quadrangular baffle 10 and located above the quadrangular baffle 10. The upper end of each round steel bar 11 is fixedly connected to the cylinder 6 and located on the inner wall of the cylinder 6. The air intake 9 is fixedly connected to the cylinder 6 and located above the cylinder 6. The quadrangular baffle 10 and the multiple round steel bars 11 form an air intake distributor. The quadrangular baffle 10 changes the direction of the airflow while uniformly distributing the gas around the perimeter, effectively reducing the vertical impact vibration of the airflow on the cooling water pipe 20.

[0022] Furthermore, the air outlet assembly 3 includes an air outlet 12 and a honeycomb noise reduction plate 13. The honeycomb noise reduction plate 13 is fixedly connected to the air outlet 12 and is located on the inner wall of the air outlet 12. The honeycomb noise reduction plate 13 has a plurality of regular hexagonal holes 14.

[0023] Furthermore, the stabilizing component 4 includes a lug 15 and two saddles 16. Both saddles 16 are fixedly connected to the cylinder 6 and located below the cylinder 6. The lug 15 is fixedly connected to the cylinder 6 and located above the cylinder 6.

[0024] Further, the cooling assembly 5 includes a cooling water inlet 17, a cooling water outlet 18, a fixing plate 19, and multiple cooling water pipes 20. Each cooling water pipe 20 is fixedly connected to the fixing plate 19 and located inside the fixing plate 19. The fixing plate 19 is fixedly connected to the cylinder 6 and located on the inner wall of the cylinder 6. The cooling water outlet 18 is fixedly connected to the cylinder 6 and located below the cylinder 6. The cooling water inlet 17 is fixedly connected to the cylinder 6 and located above the cylinder 6. Hot-end gas enters from the air inlet 9. The quadrangular baffle 10 changes the direction of the airflow and evenly distributes the gas around the cylinder, effectively reducing the vertical impact vibration of the airflow on the cooling water pipes 20. After heat exchange through the cylinder 6 and the cooling water pipes 20, the hot-end gas is finally discharged from the cylinder 6 through the honeycomb noise reduction plate 13 in the air outlet 12 and enters the next process. The design of the honeycomb noise reduction plate 13 inside the inlet 12 allows the exhaust airflow to pass more evenly through each of the regular hexagonal holes 14, dividing the large airflow into several uniform small airflows that are discharged from the cylinder 6. The area of ​​the regular hexagonal holes 14 is slightly larger than or equal to the cross-sectional area of ​​the air inlet 9 pipe, ensuring the throughput of the exhaust airflow. The setting of the fixing plate 19 facilitates the fixing of each of the cooling water pipes 20, avoiding the impact vibration of the cooling water pipes 20 caused by the large airflow. The setting of the cooling water inlet 17 and the cooling water outlet 18 facilitates the entry and exit of cold end water, ensuring the heat exchange efficiency of the cylinder 6. A discharge port is also provided on the top of the cylinder 6. The discharge port is for the purpose of preventing overpressure of the condenser, ensuring the safety of the condenser in operation. The design of the flange-type end cap 8 is conducive to the maintenance of the cooling water pipes 20. The two saddles 16 structure serve to support the weight of the condenser. The setting of the lifting lugs 15 facilitates hoisting and transportation.

[0025] In this embodiment, by setting an intake splitter, the airflow distribution direction is changed, which serves to split the flow and reduce the direction of vertical impact vibration. The smaller the vibration, the smaller the noise generated by the vibration. The quadrangular baffle 10 effectively changes the distribution direction of the intake airflow in the condenser, causing the airflow to disperse in all directions. After the intake port 9, a first-stage splitting and vibration reduction is performed. The honeycomb noise reduction plate 13 set in the outlet port 12, using the porous structure of the regular hexagonal holes 14, evenly splits the airflow from the cylinder 6 into multiple small airflows that exit the condenser. The diameter of the outlet port 12 is larger than that of the intake port 9, and the area of ​​the regular hexagonal holes 14 is slightly larger than or equal to the cross-sectional area of ​​the intake port 9. A second-stage splitting and noise reduction is performed on the honeycomb noise reduction plate 13 at the outlet port 12 for the hot-end outlet gas. This structure is more resistant to the impact of high-pressure, high-flow-rate, and high-velocity airflow. The two-stage splitter design further ensures that the airflow is evenly split in the condenser, effectively reducing the noise generated by the gas. The vibrations caused by vertical impact and flow deviation at the air inlet 9 and the air outlet 12 are mitigated by the uniform airflow distribution and the porous structure plate design, which increases the contact area and improves the noise reduction effect. This overcomes the original vibration and noise problems caused by vertical airflow impact and uneven airflow distribution, thus improving the overall noise reduction effect and service life of the condenser. It also saves the cost of adding a silencer to the air outlet 12 pipe. The quadrangular baffle 10 weakens and disperses the direction of gas vibration (the impact vibration generated by a large inlet airflow). The honeycomb noise reduction plate with multiple regular hexagonal holes 14 makes the outlet airflow uniformly distributed, resulting in a better noise reduction effect than a condenser without a flow divider and noise reduction plate. The hot-end gas can fully contact each cooling water pipe 20 in the condenser, resulting in uniform heat exchange. This effectively avoids uneven contact and insufficient heat exchange caused by gas flow deviation, improving heat exchange efficiency and avoiding the economic investment of silencer equipment on the hot-end air outlet 12 pipe of the condenser.

[0026] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the utility model.
