AI Technical Summary
随着运行时间的延长，灰尘污垢层的厚度不断增加，会产生两大关键问题：一方面，灰尘层的导热系数远低于金属翅片，形成显著的热阻屏障，严重阻碍翅片与冷却介质之间的热量传递，导致冷凝换热效率大幅下降，原本可在规定时间内完成的冷凝过程被迫延长，甚至无法达到预期的冷凝温度，直接影响后续精馏、分离等工艺的效果；另一方面，翅片间的灰尘堆积会缩小气流通道截面积，增加冷却风或冷却液的流动阻力，不仅需要额外消耗更多能源以维持介质循环，还可能因气流分布不均引发局部过热现象，缩短冷凝器的使用寿命
[0010]本实用新型与现有技术相比，具有以下优点及有益效果：本实用新型在散热翅片一侧设置有喷淋头，喷淋头可向散热翅片喷洒清洗液，以将散热翅片和冷凝管道表面的灰尘等附着物冲落，实现冷凝器的自清洁，避免附着物影响冷凝器的冷凝效果。喷淋头可相对散热翅片和冷凝管移动，以完全覆盖散热翅片和冷凝管道，喷淋头可移动使得可采用体积相对较小及喷射范围小单喷射压力大的喷淋头，以满足冷凝管道和散热翅片特殊的清洗需求。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooling device technology, specifically to a high-efficiency condenser for chemical production. Background Technology
[0002] In chemical production, condensation is a crucial process for material separation, purification, and recovery. As a core piece of equipment, the condenser's heat exchange efficiency directly determines the stability of the production process, product quality, and energy utilization. The operating environment of condensers is often accompanied by large amounts of dust, volatile chemical particles, and suspended impurities. Because existing finned tube condensers generally lack effective self-cleaning functions, these impurities easily accumulate on the fin surface, forming a dust and dirt layer. As operating time increases, the thickness of this dust and dirt layer continuously increases, leading to two major problems: First, the thermal conductivity of the dust layer is much lower than that of the metal fins, forming a significant thermal resistance barrier that severely hinders heat transfer between the fins and the cooling medium, resulting in a significant decrease in condensation heat exchange efficiency. The condensation process, which could have been completed within a specified time, is forced to be prolonged, or even fails to reach the expected condensation temperature, directly affecting the effectiveness of subsequent distillation and separation processes. Second, dust accumulation between the fins reduces the cross-sectional area of the airflow channel, increasing the flow resistance of the cooling air or coolant. This not only requires additional energy to maintain medium circulation but may also cause localized overheating due to uneven airflow distribution, shortening the condenser's service life. To address the aforementioned problems, this utility model provides a high-efficiency condenser for chemical production. Utility Model Content
[0003] The purpose of this invention is to provide a high-efficiency condenser for chemical production.
[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: A high-efficiency condenser for chemical production includes: a mounting shell, on which a reciprocating coiled condensing pipe is provided, and heat dissipation fins are connected to the outside of the condensing pipe. The number of heat dissipation fins is several and they are evenly distributed inside the mounting shell along the length direction of the mounting shell. The mounting housing is provided with a mounting bracket, and the mounting bracket is provided with a fan. The airflow direction of the fan is towards the condensation pipe and the heat dissipation fins. A slide rail along the height direction of the heat dissipation fins is provided on the mounting housing between the heat dissipation fins and the fan. A sliding plate is slidably arranged in the slide rail. A plurality of spray heads are provided on the sliding plate. The spray heads are connected to the infusion pipes provided on the sliding plate. The spray head is directed toward the heat dissipation fins, and the spray range covers all of the heat dissipation fins along the length of the mounting housing.
[0005] Based on the above scheme and as a preferred embodiment of the above scheme, the condensation pipe passes through the opposite two sides of the mounting housing, and the section between the opposite two sides is straight, and the heat dissipation fins are connected to the straight section.
[0006] Based on the above scheme and as a preferred embodiment of the above scheme, the slide rail is a grooved slide rail, the two ends of the sliding plate are slidably fitted inside the slide rail, and one end of the sliding plate is threadedly fitted with a lead screw disposed inside the slide rail; one end of the lead screw is connected to the drive motor for transmission.
[0007] Based on the above scheme and as a preferred embodiment of the above scheme, a mounting plate is provided on the top of the slide rail, and the mounting plate connects the two slide rails; the drive motor is mounted on the mounting plate.
[0008] Based on the above scheme and as a preferred embodiment of the above scheme, the infusion tube is a rigid tube in the shape of L, with its horizontal branch connected to the spray head and its vertical branch slidably connected to the mounting plate, and the top of the vertical branch is always located above the mounting plate.
[0009] Based on the above scheme and as a preferred embodiment of the above scheme, the other end of the sliding plate is slidably engaged with a sliding rod disposed in another slide rail.
[0010] Compared with the prior art, this invention has the following advantages and beneficial effects: A spray head is provided on one side of the heat dissipation fins. The spray head can spray cleaning fluid onto the heat dissipation fins to wash away dust and other adhering substances on the surface of the heat dissipation fins and condenser pipes, achieving self-cleaning of the condenser and preventing adhering substances from affecting the condenser's condensation effect. The spray head can move relative to the heat dissipation fins and condenser pipes to completely cover them. The movable nature of the spray head allows for the use of relatively small spray heads with a small spray range and high single spray pressure to meet the special cleaning needs of the condenser pipes and heat dissipation fins.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art.

[0017] like Figure 1 and Figure 2 As shown, a high-efficiency condenser for chemical production includes: a mounting housing 1, on which a reciprocating coiled condensing pipe 2 is disposed. Specifically, the condensing pipe 2 passes through opposite sides of the mounting housing 1, and the section between the opposite sides is arranged in a straight line. The condensing pipe 2 is a rigid pipe with an inlet and an outlet.
[0018] The condenser pipe 2 is externally connected to several heat dissipation fins 3, which are evenly distributed inside the mounting housing 1 along its length. The heat dissipation fins 3 are connected to the straight section of the condenser pipe 2 located inside the mounting housing 1. The straight section of the condenser pipe 2 is arranged along the length of the mounting housing 1.
[0019] The mounting housing 1 is provided with a mounting bracket 4, and a fan 5 is provided on the mounting bracket 4. The fan 5 blows air towards the condenser pipe 2 and the heat dissipation fins 3 to achieve air cooling of the condenser pipe 2 and the heat dissipation fins 2.
[0020] like Figure 2 As shown, a slide rail 6 is provided on the mounting housing 1 between the heat dissipation fins 3 and the fan 5, running along the height direction of the heat dissipation fins 3. A sliding plate 7 is slidably mounted inside the slide rail 6, and several spray heads 8 are mounted on the sliding plate 7. The spray heads 8 are connected to infusion pipes 9 mounted on the sliding plate 7. The sliding plate 7, spray heads 8, and infusion pipes 9 can slide along the slide rail 6 to achieve spraying at different positions.
[0021] The spray head 8 is directed towards the heat dissipation fins 3, and the spray range covers all the heat dissipation fins 3 along the length of the mounting housing 1. At the same time, the spray head 8 slides along the slide rail 6, and its spray range covers the heat dissipation fins 3 and the condensation pipe 2 along the height of the mounting housing 1, achieving full-area cleaning of the condensation pipe 2 and the heat dissipation fins 3.
[0022] The slide rail 6 is a recessed type, formed by the recess in the side wall of the mounting housing 1. The sliding plate 7 is slidably fitted inside the slide rail 6 at both ends, and one end of the sliding plate 7 is threadedly engaged with a lead screw 10 located inside the slide rail 6. One end of the lead screw 10 is connected to a drive motor 11. The drive motor 11 is connected to a control device and can drive the lead screw 10 to rotate under the control of the control device, thereby causing the sliding plate 7 to rise and fall.
[0023] A mounting plate 12 is provided on the top of the slide rail 6. The mounting plate 12 connects the two slide rails 6, and the drive motor 11 is mounted on the mounting plate 12. The mounting plate 12 not only serves as a support component but also as a limiting component, which can limit the distance the sliding plate 7 rises and prevent it from disengaging from the slide rail 6.
[0024] like Figure 3 and Figure 4 As shown, the infusion tube 9 is a rigid L-shaped tube. Its horizontal branch connects to the shower head 8, and its vertical branch is slidably connected to the mounting plate 12, with the top of the vertical branch always positioned above the mounting plate 12. The rigid tube does not bend, thus fixing the position of the infusion tube 9 within the mounting housing 1 and preventing interference. The top of the vertical branch of the infusion tube 9 is used to connect to an external pipe, at least one section of which is a flexible or telescopic tube to accommodate the sliding of the shower head 8.
[0025] The other end of the sliding plate 7 is slidably engaged with the sliding rod 13 located in another slide rail 6 to improve the stability of the sliding plate 7.
[0026] Working process: The control device controls the drive motor 11 to work at regular intervals or under the input command of the operator. The drive motor 11 drives the sliding plate 7, the spray head 8 and the infusion pipe 9 to rise and fall. At the same time, the spray head 8 sprays cleaning fluid onto the heat dissipation fins 3 and the condensation pipe 2.
[0027] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
