Description

Technical Field

[0001] This utility model relates to the field of ethylene compression technology, specifically to a cooling device for an ethylene compressor. Background Technology

[0002] In the industrial sector, the petrochemical industry is undoubtedly one of the important pillars of economic development. Ethylene, as a core basic raw material in the petrochemical field, is widely used in many fields such as plastics, rubber, and fibers. From everyday food packaging and household goods to automotive parts and building materials in industrial production, ethylene products have long been deeply integrated into people's lives and production processes. Ethylene compressors are an indispensable part of the ethylene production and processing process, responsible for compressing ethylene gas to a specific pressure to promote the smooth operation of the entire industrial chain. However, compressors generate a lot of heat when they work continuously. If this heat is not properly handled, it will become a major hidden danger that restricts production efficiency and endangers production safety.

[0003] The core component of the ethylene compressor cooling device is a combination of a cooling fan and heat sinks. The heat sinks are attached to the parts of the ethylene compressor that need to be cooled. When the fan rotates, it forces the surrounding air to flow quickly over the surface of the heat sinks. According to the principle of heat transfer, heat will be conducted from the compressor parts with higher temperatures to the flowing air through the heat sinks, thus achieving heat dissipation.

[0004] In existing technologies, air-cooled cooling devices are commonly used. When the ambient temperature is too high, the cooling efficiency will drop sharply, making it difficult to control the temperature of the ethylene compressor within the ideal range. This will seriously affect the performance and stability of the compressor, ultimately leading to frequent compressor failures, forced production line shutdowns, and huge economic losses to enterprises. Therefore, an ethylene compressor cooling device is proposed to solve the above problems. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] In this invention, the coolant enters the condenser tube through the inlet and flows under the guidance of the return baffle, increasing the contact area and time between the coolant and the surrounding thermal environment. This allows for more efficient absorption of the heat generated during compression, reducing the temperature of the ethylene gas and compressor components, preventing equipment damage and performance degradation due to excessive temperature, and extending the compressor's service life.

[0026] Please see Figure 1-4 An ethylene compressor cooling device includes a housing 1, a support frame 3 on the top of the housing 1, a cooling mechanism 4 on the top of the support frame 3, and a compression mechanism 6 on the inner side of the housing 1. The support frame 3 supports the cooling mechanism 4, and the housing 1 provides a relatively enclosed and stable working space for the internal compression mechanism 6. The cooling mechanism 4 includes a heat-insulating protective shell 401, which reduces heat exchange between the cooling mechanism 4 and the external environment, prevents external heat from entering the cooling mechanism 4 and affecting the cooling effect, and also reduces the loss of cold energy inside the cooling mechanism 4. A protective shell 406 is provided on the inner side of the heat-insulating protective shell 401, and multiple return baffles 402 are fixedly connected to the protective shell 406. A water-cooling component is fixedly connected to the inner side of the return baffles 402.

[0027] The water-cooling assembly includes a condenser tube 403, the outer side of which is fixedly connected to the inner side of a return baffle 402. A protective shell 406 is used to protect the internal water-cooling assembly and the return baffle 402. The return baffle 402 is used to guide the flow path of ethylene. The condenser tube 403 serves as a flow channel for the coolant, absorbing the heat generated during compression through the circulation of the coolant. One end of the condenser tube 403 is fixedly connected to a water inlet 404, and the other end is fixedly connected to a water outlet 405. The water inlet 404 is the inlet for the coolant to enter the condenser tube 403. The outer side of the heat-insulating protective shell 401 is fixedly connected to the outer side of the support frame 3. The outer side of the water outlet 405 is fixedly connected to the inner side of the protective shell 406, and the outer side of the water inlet 404 is fixedly connected to the inner side of the protective shell 406.

[0028] The compression mechanism 6 includes a rotating zigzag column 602, the outer side of which is rotatably connected to the inner side of the housing 1. A push assembly is rotatably connected to the outer side of the rotating zigzag column 602, and a valve assembly is provided directly above the push assembly.

[0029] The pushing assembly includes a rotating ring 603 and a rotating zigzag column 602 for converting the rotational motion of the motor 601 into a pushing motion. The outer side of the rotating ring 603 is rotatably connected to the outer side of the rotating zigzag column 602. A pushing column 604 is fixedly connected to the top of the rotating ring 603. The rotating ring 603 is used to convert the rotational motion of the rotating zigzag column 602 into the up-and-down movement of the pushing column 604. A compression piston 605 is fixedly connected to the top of the pushing column 604. The outer side of the compression piston 605 is slidably connected to the inner side of the housing 1. The pushing column 604 is used to transmit the motion of the rotating ring 603 to the compression piston 605, pushing the compression piston 605 to slide up and down inside the housing 1 to compress ethylene gas. The compression piston 605 is used to draw in ethylene gas by changing the size of the space inside the housing 1.

[0030] The valve assembly includes an intake valve 606, which controls the intake process of ethylene gas. When the pressure inside the housing 1 is lower than the external pressure, the intake valve 606 opens to allow ethylene gas to enter. When the pressure inside the housing 1 increases, the intake valve 606 closes to prevent gas backflow. The outer side of the intake valve 606 is fixedly connected to the lower part of the air inlet of the housing 1. An exhaust valve 607 is fixedly connected to the upper part of the air outlet of the housing 1. The exhaust valve 607 controls the discharge process of the compressed ethylene gas. When the pressure inside the outer casing 1 reaches a certain value, the exhaust valve 607 opens to discharge the compressed ethylene gas. When the pressure inside the outer casing 1 decreases, the exhaust valve 607 closes to prevent external gas from entering. A motor 601 is fixedly connected to the outside of the outer casing 1. The motor 601 is used to drive the zigzag column 602 to rotate. The drive end of the motor 601 is fixedly connected to the outside of the rotating zigzag column 602. A base plate 5 is fixedly connected to the bottom of the outer casing 1. A push handle is provided on the outside of the base plate 5 and a caster wheel is provided at its bottom. A high-pressure input pipe 2 is fixedly connected to the port of the outer casing 1. The outside of the high-pressure input pipe 2 is fixedly connected to the outside of the protective shell 406.

[0031] The working principle of this utility model is as follows: When compressing ethylene gas, the motor 601 drives the rotating zigzag column 602 to rotate inside the outer casing 1. As the rotating zigzag column 602 rotates, the rotating ring 603 makes a corresponding circular motion on its outer side. Due to the special zigzag shape of the rotating zigzag column 602, the rotating ring 603 drives the push column 604 to move up and down reciprocally. The compression piston 605 at the top of the push column 604 slides up and down inside the outer casing 1 under the drive of the push column 604. When the compression piston 605 moves downward, the space inside the outer casing 1 increases and the pressure decreases. At this time, the intake valve 606 opens, and the ethylene gas enters the interior of the outer casing 1 through the high-pressure input pipe 2 from the intake port. When the compression piston 605 moves upward, the space inside the outer casing 1 decreases and the pressure increases. The intake valve 606 closes, the exhaust valve 607 opens, and the compressed ethylene gas is discharged from the exhaust port and discharged from the high-pressure input pipe 2 to the cooling mechanism 4 for cooling, ensuring the normal operation of the compressor.

[0032] Coolant enters the condenser tube 403 through the inlet 404. The condenser tube 403 is fixed inside the return baffle 402. The return baffle 402 guides the flow of coolant and increases the heat dissipation area. The coolant flows in the condenser tube 403, absorbing heat from the surroundings, and then flows out from the outlet 405. At the same time, the heat insulation shell 401 provides heat insulation, reducing heat exchange between the cooling mechanism 4 and the external environment, and improving cooling efficiency. The protective shell 406 protects the internal water-cooling components.

[0033] In this invention, the coolant enters the condenser tube through the inlet and flows under the guidance of the reflux baffle, increasing the contact area and time between the coolant and the surrounding thermal environment. This allows for more efficient absorption of the heat generated during compression, reducing the temperature of the ethylene gas and compressor components, preventing equipment damage and performance degradation due to excessive temperature, and extending the compressor's service life.

[0034] In this invention, the rotating zigzag column, rotating ring, pushing column, and compression piston are driven by a motor to work together, thereby achieving efficient compression of ethylene gas. The specially zigzag-shaped rotating zigzag column ingeniously transforms the circular motion of the motor into the reciprocating motion of the compression piston, which can control the compression process, improve compression efficiency, and thus increase the amount of ethylene gas compressed per unit time, meeting the needs of large-scale production.
