Description

Technical Field

[0001] This application relates to the field of condenser equipment, and in particular to enamel condensers. Background Technology

[0002] Disc condensers are a type of high-efficiency, compact heat exchanger. They form complex flow channels through stacked discs, offering advantages such as large heat exchange area and compact size.

[0003] However, when using a traditional disc condenser, the flow cross-sectional area suddenly expands as steam enters the condensing chamber from the inlet pipe, resulting in a reduction in steam volume. At the same time, because the steam flow follows the "principle of least resistance," most of the steam will directly impact and concentrate in a few channels near the center of the inlet, while the flow at the edges and far from the inlet will have little steam flow or even form stagnant zones.

[0004] The aforementioned steam flow phenomenon leads to a large number of "dead zones" inside the equipment, leaving a significant portion of the expensive heat exchange area idle, and the overall condensation efficiency far below the design value.

[0005] In other words, existing technologies have the following technical problems: when using ordinary enamel-lined disc condensers, the increased steam flow area leads to a decrease in heat exchange efficiency. Therefore, an enamel-lined condenser is proposed to address these issues. Summary of the Invention

[0006] This application provides an enamel-lined condenser to solve the problem that, in the use of ordinary enamel-lined disc condensers in the prior art, the heat exchange efficiency decreases due to the increased steam flow area.

[0007] According to one aspect of this application, an enamel-lined condenser is provided, comprising:

[0008] Enameled disc assembly, there are several enamel disc assemblies, and several enamel disc assemblies are connected in series;

[0009] The enamel disc assembly includes a disc body, an inner cavity inside the disc body, and a steam distribution component inside the inner cavity.

[0010] The steam distribution assembly includes conical plates;

[0016] Furthermore, a conical plate is provided inside the disc cavity, and a support rod is fixedly connected to the bottom end of the conical plate to suspend and fix the conical plate at the axial position of the disc cavity.

[0017] A conical flow guide gap is formed between the conical plate and the inner wall of the disc body.

[0018] Furthermore, the outer wall of the conical plate is provided with spiral guide ridges, and there are several spiral guide ridges distributed in an equidistant spiral pattern.

[0019] Furthermore, the adjustment assembly includes a connecting cavity, a transverse sleeve, a support sleeve, and an adjustment rod;

[0020] The connecting cavity is fixedly installed at the bottom end of the condensate outlet, and a transverse sleeve is fixedly connected inside the connecting cavity.

[0021] A support sleeve is fixedly connected to the upper end of the transverse sleeve, and an adjusting rod is slidably connected in the inner cavity of the support sleeve. The upper end of the adjusting rod is fixedly connected to the bottom end of the support connecting rod.

[0027] The second bevel gear meshes with the first bevel gear, and the other end of the transmission rod extends to the side wall of the connecting cavity. An adjustment handle is also fixedly connected to one end of the transmission rod.

[0039] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0040] Please see Figure 1 and Figure 2 As shown, the enamel-lined condenser includes:

[0041] Enameled disc assembly 1, several enamel disc assemblies 1 are provided, and several enamel disc assemblies 1 are connected in series to form a condensation heat exchange body.

[0042] The enamel disc assembly 1 includes a disc body 101, an inner cavity 1011 is provided inside the disc body 101, and a steam distribution assembly 3 is provided in the inner cavity 1011.

[0043] The steam distribution assembly 3 includes a conical plate 301 for optimizing the flow distribution of steam in the disc cavity 1011.

[0044] The bottom of the steam distribution assembly 3 is connected to an adjustment assembly 4, which is used to adjust the axial position of the conical plate 301.

[0045] This application, through the combination of enamel disc assembly 1 and steam distribution assembly 3, is suitable for corrosive environments and can improve the uniformity of steam distribution and condensation heat exchange efficiency, thereby overcoming the flow field defects of traditional metal disc condensers. It is particularly suitable for condensation applications in chemical, pharmaceutical, and offshore platforms where corrosive media exist.

[0046] In a preferred embodiment of this application, see [reference] Figure 2 and Figure 3 As shown, an annular edge 102 is fixedly provided on the arc-shaped outer wall of the disc body 101. Several annular edges 102 are connected by connecting rods 106. Specifically, several connecting rods 106 are provided, and each connecting rod 106 passes through the corresponding mounting holes on several annular edges 102 from top to bottom, and is engaged with the annular edges 102 by threads and locking nuts.

[0047] The connecting rod 106 uses locking nuts tightened at both ends to press several annular edges 102 between the flanges at both ends and lock them in place, thereby assembling multiple disc bodies 101 into a sturdy integral module.

[0048] Further, see Figure 3 As shown, a sleeve shell 110 is also fixedly connected to the outer wall of the disc body 101. The adjacent disc bodies 101 and sleeve shell 110 are combined to form a medium cavity 109, forming a flow channel for the flow of cooling medium.

[0049] A medium output end 103 is fixedly connected to one side of the medium cavity 109 for leading out the cooling medium after absorbing heat; a medium input end 105 is fixedly connected to the other side of the medium cavity 109 for introducing the cooling medium to be input.

[0050] A medium connecting pipe 104 is also provided between the medium chambers 109 to connect the cooling medium channels of adjacent medium chambers 109 in series, forming a continuous cooling medium flow.

[0051] With this technical solution, when the cooling medium flows in from the medium input end 105, it can flow through each medium cavity 109 connected in series in sequence, thereby fully absorbing the latent heat of condensation of the vapor in the inner cavity 1011 of the disc and transmitted through the disc body 101, thereby achieving efficient condensation.

[0052] In one specific embodiment of this application, see [reference]. Figure 3 and Figure 5 As shown, a conical plate 301 is provided inside the disc cavity 1011. A support rod 302 is fixedly connected to the bottom end of the conical plate 301 to suspend and fix the conical plate 301 at the axial position of the disc cavity 1011.

[0053] A conical guide gap is formed between the conical plate 301 and the wall of the inner cavity 1011 of the disc body 101, which is used to promote more uniform diffusion of steam to the entire circumferential wall of the inner cavity 1011 of the disc.

[0054] This technical solution, by setting a conical plate 301, allows steam to enter from the top and first impact the conical surface of the plate 301, forcing it to change its flow direction and enter the annular conical guide gap. This enables the steam to contact the enamel wall of the entire inner cavity 1011 of the disc more evenly and fully, thereby avoiding steam short-circuiting and flow dead zones, improving the utilization rate of the heat exchange area, and optimizing the flow field distribution.

[0055] Furthermore, to further enhance the effect of steam flow on thinning and removing the condensate film, refer to... Figure 5 As shown, a spiral guide ridge 303 is also provided on the outer wall of the conical plate 301. Several spiral guide ridges 303 are provided and distributed in an equidistant spiral pattern to form a spiral flow channel that guides the steam to generate swirling flow.

[0056] With this technical solution, when steam flows through the annular conical gap with spiral guide ridge 303, it can be given rotational motion to generate swirling flow. Then, the centrifugal force generated by the swirling flow is used to thin the condensate film on the wall and accelerate its downward discharge, thereby further improving the condensation heat transfer efficiency.

[0057] In a preferred embodiment of this application, see [reference] Figure 3 and Figure 4 As shown, in order to adjust the height of the conical plate 301 to adapt to different steam load conditions, the adjustment assembly 4 includes a connecting cavity 401, a transverse sleeve 402, a support sleeve 403, and an adjustment rod 404.

[0058] The connecting cavity 401 is fixedly installed at the bottom end of the condensate output end 108, and a transverse sleeve 402 is fixedly connected in the inner cavity of the connecting cavity 401.

[0059] A support sleeve 403 is fixedly connected to the upper end of the transverse sleeve 402. An adjusting rod 404 is slidably connected in the inner cavity of the support sleeve 403. The upper end of the adjusting rod 404 is fixedly connected to the bottom end of the support connecting rod 302, and is used to transmit the axial movement of the adjusting rod 404 to the support connecting rod 302 and the tapered plate 301.

[0060] The support sleeve 403 is equipped with an adjustment unit inside, which is used to drive the adjustment rod 404 to perform precise axial lifting and lowering movements.

[0061] Furthermore, the adjustment unit of the adjustment assembly 4 includes a threaded sleeve 405, an adjustment screw 406, and a transmission part.

[0062] A threaded sleeve 405 is fixedly installed in the inner cavity of the adjusting rod 404. An adjusting screw 406 is rotatably connected in the inner cavity of the support sleeve 403. One end of a connecting rod 407 is fixedly connected to the bottom end of the adjusting screw 406. The other end of the connecting rod 407 is rotatably connected to the bottom wall of the inner cavity of the transverse sleeve 402. The adjusting screw 406 passes through the threaded sleeve 405 and is threadedly engaged with the threaded sleeve 405, forming a threaded pair that converts the rotational motion of the adjusting screw 406 into the linear motion of the adjusting rod 404.

[0063] To prevent the adjusting rod 404 from rotating with the adjusting screw 406 and to ensure that it only moves axially, a guide groove is provided between the adjusting rod 404 and the support sleeve 403. Specifically, a protruding key is provided on the outer wall of the adjusting rod 404, and a vertical guide groove is opened on the inner wall of the support sleeve 403 to cooperate with it. The circumferential limit is achieved through the cooperation of the protruding key and the guide groove.

[0064] Furthermore, the transmission unit includes a first bevel gear 408, a second bevel gear 409, and a transmission rod 410.

[0065] A first bevel gear 408 is fixedly connected to the arc-shaped wall of the connecting rod 407, and a transmission rod 410 is rotatably connected to the inner cavity of the transverse sleeve 402. A second bevel gear 409 is fixedly connected to one end of the transmission rod 410.

[0066] The second bevel gear 409 meshes with the first bevel gear 408. The other end of the transmission rod 410 extends to the side wall of the connecting cavity 401. An adjustment handle 411 is also fixedly connected to one end of the transmission rod 410.

[0067] With this technical solution, when the operator rotates the adjusting handle 411 from outside the equipment, it can drive the transmission rod 410 and the second bevel gear 409 to rotate, thereby driving the first bevel gear 408 and the adjusting screw 406 to rotate. The threaded pair can drive the adjusting rod 404 and the conical plate 301 to rise and fall, thereby changing the size of the flow guide gap of the annular cone. By adjusting the size of the flow guide gap, a suitable match can be made according to the amount of steam entering, thereby further adapting to various working conditions.

[0068] To provide a passive solution that can adaptively adjust the guide gap according to steam pressure, see [reference needed]. Figure 6 As shown, in another embodiment of the steam distribution assembly 3:

[0069] The support link 302 includes a support sleeve 3021, a floating rod 3022, and a support spring 3023.

[0070] A floating rod 3022 is slidably connected in the inner cavity of the support sleeve rod 3021, forming a connection that can slide relative to each other axially. The upper end of the floating rod 3022 is fixedly connected to the bottom of the conical plate 301, and the bottom end of the floating rod 3022 is fixedly connected to a support spring 3023.

[0071] Specifically, the stiffness and preload of the support spring 3023 need to be designed according to the steam pressure range of the design working conditions. Its elastic deformation is used to balance the steam dynamics acting on the conical plate 301. In practice, a high-temperature resistant and relaxation-resistant alloy spring material is selected. By abutting the other end of the support spring 3023 against the bottom of the inner cavity of the support sleeve 3021, the conical plate 301 can be pushed down when the steam pressure increases, increasing the annular gap to reduce resistance. When the steam pressure decreases, it is pushed back by the support spring 3023, reducing the annular gap to maintain the flow rate, thereby achieving adaptive adjustment to different steam flow rates and maintaining a better flow field state.

[0072] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software and methods.

[0073] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
