Description

Technical Field

[0001] This utility model relates to the field of flow guide baffle technology, specifically a steam flow guide baffle device for a triple-effect evaporator. Background Technology

[0002] During the operation of a triple-effect evaporator, steam, as the key medium for heat exchange, directly affects the equipment's performance and service life due to its state upon entering the heating chamber. Some existing triple-effect evaporators, due to simplified design or technological limitations, lack a dedicated steam flow guide baffle structure.

[0003] When high-pressure steam is injected directly into the heating chamber from the steam inlet, the high-speed steam forms a "direct jet" that directly impacts localized areas of the heating tube bundle. Prolonged exposure to this impact can lead to tube wall wear and high-frequency vibration, subsequently causing weld cracking at the tube ends and leaks in the tube body. This not only shortens the lifespan of the tube bundle but also increases the frequency and cost of equipment maintenance. Furthermore, damage to heat exchange components can affect the overall heat exchange efficiency and stable operation of the evaporator. Therefore, targeted technical solutions are urgently needed to address these issues. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 The present invention provides a steam guide baffle device for a triple-effect evaporator, comprising: a fixing ring 2 installed on the inner wall of the air inlet pipe 1, and a connecting ring 3 installed on the inner wall of the fixing ring 2. The upper and lower ends of the outer wall of one side of the fixing ring 2 are connected to fixing rods 4, and a first component 5, a second component 6 and a third component 7 are sequentially sleeved on the outer wall of the two fixing rods 4. The first component 5, the second component 6 and the third component 7 form a hemispherical concave structure, and a guide component 8 is installed at one end of the inner wall of the air inlet pipe 1.

[0020] It should be noted that: the device is installed on the inner wall of the inlet pipe 1 via the fixing ring 2, and the connecting ring 3 enhances the connection stability between the fixing ring 2 and the inlet pipe 1, providing a foundation for the installation of subsequent components; the fixing rod 4 is used to sleeve the first component 5, the second component 6, and the third component 7, limiting their installation and movement trajectory. When high-pressure steam enters the inlet pipe 1, the hemispherical concave structure formed by the first component 5, the second component 6, and the third component 7 directly receives the steam, using the concave shape to disperse the impact stress of the "direct jet" steam to the surroundings, avoiding concentrated steam impact on the heating tube bundle.

[0021] Under the action of steam impact, the first component 5, the second component 6 and the third component 7 undergo tensile deformation, further absorbing the steam impact energy and playing a buffering role. At the same time, the gap between the three components increases, providing a flow channel for the buffered steam and reducing the local accumulation of steam.

[0022] The buffered steam flows to the guide component 8 at one end of the inner wall of the inlet pipe 1. The guide component 8 achieves uniform flow, allowing the steam to enter the heating chamber evenly, improving the heat exchange efficiency with the heating tube bundle, and solving the problems of tube bundle wear, leakage and low thermal efficiency caused by direct steam injection in the original equipment.

[0023] In a preferred embodiment, the first component 5 includes a first ring 501, first sliding plates 502 mounted on both ends of the outer wall of the first ring 501, and first springs 503 connected to the outer wall of one side of the two first sliding plates 502, and one end of each of the two first springs 503 is connected to the outer wall of the fixed ring 2.

[0024] It should be noted here that: in the first component 5, the first component ring 501 is the basic component that constitutes the hemispherical concave structure, and the first sliding plates 502 at both ends of its outer wall are sleeved on the fixed rod 4 and can slide along the fixed rod 4.

[0025] When the high-pressure steam impacts the first component ring 501, the first component ring 501 drives the first sliding plate 502 to move away from the fixed ring 2 along the fixed rod 4. At this time, the first spring 503 connected to one side of the first sliding plate 502 is stretched.

[0026] The stretching deformation of the first spring 503 absorbs part of the steam impact energy, thus achieving buffering. At the same time, the elastic force of the first spring 503 can drive the first sliding plate 502 and the first component ring 501 to reset when the steam pressure changes, ensuring that the first component 5 continues to play a stable role in dispersing impact and buffering.

[0027] In a preferred embodiment, the second component 6 includes a second ring 601, second sliding plates 602 mounted on both ends of the outer wall of the second ring 601, and second springs 603 connected to the outer wall of one side of the two second sliding plates 602, with one end of each of the two second springs 603 connected to the outer wall of the two first sliding plates 502 respectively.

[0028] It should be noted here that: the second component ring 601 of the second component 6 cooperates with the first component ring 501 to form part of the hemispherical concave structure, and the second sliding plate 602 is sleeved on the fixed rod 4 and can slide with the steam impact.

[0029] When high-pressure steam impacts, the second component ring 601 is driven by the impact force to slide the second sliding plate 602 along the fixed rod 4, causing the second spring 603 on one side of the second sliding plate 602 to be stretched because the other end of the second spring 603 is connected to the first sliding plate 502.

[0030] The stretching deformation of the second spring 603 further absorbs the steam impact energy, and works in conjunction with the first component 5 to enhance the buffering effect; and the elastic force of the second spring 603 can assist the second sliding plate 602 and the second component ring 601 to reset, ensuring that the second component 6 always stably cooperates with the first component 5 and the third component 7, and maintaining the integrity of the hemispherical concave structure.

[0031] In a preferred embodiment, the third component 7 includes a third ring 701, third sliding plates 702 mounted on both ends of the outer wall of the third ring 701, and third springs 703 connected to the outer wall of one side of the two third sliding plates 702, with one end of each of the two third springs 703 connected to the outer wall of the two second sliding plates 602 respectively.

[0032] It should be noted here that the third component ring 701 of the third component 7, together with the first component ring 501, the second component ring 601 and one end of the flow guiding component 8, forms a hemispherical concave structure. The third sliding plate 702 is sleeved on the fixed rod 4 to provide sliding support for the third component ring 701.

[0033] When the high-pressure steam impacts the third component ring 701, the third component ring 701 drives the third sliding plate 702 to slide along the fixed rod 4, causing the third spring 703 on one side of the third sliding plate 702 to be stretched (the other end of the third spring 703 is connected to the second sliding plate 602).

[0034] The tensile deformation of the third spring 703, together with the first spring 503 and the second spring 603, forms a three-stage buffer to maximize the absorption of steam impact energy. At the same time, the elastic force of the third spring 703 can drive the third sliding plate 702 and the third component ring 701 to reset, ensuring the continuous stability of the hemispherical concave structure composed of the three components and efficiently dispersing the steam impact stress.

[0035] In a preferred embodiment, the first sliding plate 502, the second sliding plate 602 and the third sliding plate 702 all form a sliding fit with the outer wall of the fixed rod 4.

[0036] It should be noted that the first sliding plate 502, the second sliding plate 602 and the third sliding plate 702 all form a sliding fit with the outer wall of the fixed rod 4, which limits the movement of the three sliding plates to the axial direction of the fixed rod 4, thus preventing the sliding plates from shifting laterally or wobbling.

[0037] In a preferred embodiment, the flow guiding component 8 includes a flow guiding block 801, a plurality of equidistant flow guiding grooves 802 formed on the outer wall of the flow guiding block 801, a mounting rod 803 mounted on one end of the flow guiding block 801, and a circular plate 804 mounted on one end of the mounting rod 803.

[0038] It should be noted here that: after being buffered by the first component 5, the second component 6 and the third component 7, the steam flows into the guide block 801. When the steam flows on the surface of the guide block 801, it will be divided and guided by the guide groove 802, breaking the disordered flow state of the steam, so that the steam is evenly distributed and flows along the guide groove 802 to the heating chamber.

[0039] The evenly distributed steam can fully contact the heating tube bundle, avoiding local overheating or insufficient steam coverage, thus improving heat exchange efficiency and inhibiting scale deposition, solving the problem of low heat exchange efficiency in the original equipment.

[0040] Working principle:

[0041] Component installation and foundation positioning: The device is installed on the inner wall of the intake pipe 1 via the fixing ring 2; the two fixing rods 4 on one side of the fixing ring 2 provide sliding mounting tracks for the first component 5, the second component 6, and the third component 7, ensuring that the three components move in a fixed direction.

[0042] Buffering and shock dispersion of high-pressure steam:

[0043] When high-pressure steam enters the inlet pipe 1, it first comes into contact with the hemispherical concave structure composed of the first component ring 501, the second component ring 601, the third component ring 701 and the circular plate 804. The concave shape disperses the impact stress of the "direct jet" steam to the surrounding area, avoiding the steam from concentrating and impacting the local heating tube bundle.

[0044] The steam impact force drives the three component rings to push the corresponding first sliding plate 502, second sliding plate 602, and third sliding plate 702 respectively, sliding along the fixed rod 4 away from the fixed ring 2. At this time, the first spring 503 connecting the first sliding plate 502 and the fixed ring 2, the second spring 603 (connecting the second sliding plate 602 and the first sliding plate 502), and the third spring 703 (connecting the third sliding plate 702 and the second sliding plate 602) are stretched synchronously, absorbing the steam impact energy through spring deformation, and realizing secondary buffering.

[0045] During the sliding process, the gap between the three components increases with the sliding distance, providing a smooth flow channel for the buffered steam and preventing steam from accumulating locally and causing additional impact.

[0046] Stable fit of sliding engagement: The first sliding plate 502, the second sliding plate 602, and the third sliding plate 702 all form a sliding engagement with the fixed rod 4, limiting the sliding direction to the axis of the fixed rod to prevent the component from shifting laterally or shaking; when the steam pressure changes, the spring elastic force can drive the sliding plate and the component ring to reset, ensuring the continuous stability of the hemispherical concave structure and maintaining the buffering and dispersion effect.

[0047] Uniform steam flow and enhanced heat exchange: The buffered steam flows towards the guide assembly 8 at one end of the inner wall of the inlet pipe 1.

[0048] Multiple equidistant guide grooves 802 on the outer wall of the guide block 801 divide and guide the steam, breaking the disordered flow state.

[0049] The steam, after being regulated by the guide channel 802, is evenly distributed and can fully contact the heating tube bundle, avoiding local overheating or insufficient steam coverage. This not only improves heat exchange efficiency but also reduces scale buildup, extends the service life of the tube bundle, and lowers equipment maintenance costs.

[0050] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
