Description

Technical Field

[0001] This utility model relates to the field of demister technology, specifically to a baffle plate type demister device. Background Technology

[0002] A baffle plate demister is a commonly used device that uses physical means to separate liquid mist, droplets, or foam entrained in a gas from the gas phase. Its core objective is to prevent liquid from flowing with the gas, causing equipment corrosion, material loss, or reduced process efficiency.

[0003] For example, Chinese utility model patent CN216320575U, entitled "A Baffle Plate Demister and a Demister Device Using the Demister," relates to the field of demisters. It includes a frame and a demister assembly disposed within the frame. The demister assembly comprises several parallel demister plates, which are fixedly connected to the frame. The demister plates are inclined relative to the gas flow direction, and a guide column is fixedly connected to one side of the demister plate along its length. The outer wall of the guide column away from the demister plate is curved. This device exhibits low gas flow resistance, allowing gas to pass quickly through the demister plates. Fine droplets, under inertia, impact the demister plates and accumulate along the plates on a tail plate. The fine droplets then coalesce into larger droplets, which, under their own weight, drip down the tail plate, ensuring effective demistering of the fine droplets.

[0004] When high-speed steam flows along a horizontally positioned flow direction, it easily reaches a critical velocity value on the baffle plate. This causes the droplets that have accumulated near the baffle plate outlet to undergo re-separation before being discharged, and they flow along with the high-speed airflow, resulting in the failure of the separation process and poor defoaming effect. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a baffle plate type demister to solve the technical problem in the prior art where high-speed steam, after flowing along a horizontally set flow direction, will separate and carry away the liquid droplets that have accumulated near the outlet of the baffle plate, resulting in poor demister effect.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This utility model provides a baffle plate type demister, comprising: The shell is hollow inside and has an L-shaped demisting channel. The outer wall of the shell has an air inlet and an air outlet that communicate with the demisting channel. A demisting component is disposed relative to the air outlet and built into the demisting channel, and is used to separate liquid mist, droplets or foam in the gas flowing through the demisting channel.

[0007] In some embodiments, the air inlet is disposed on the side wall of the housing, the air outlet is disposed on the top of the housing, and the axis of the air outlet is perpendicular to the axis of the air inlet to form the defoaming channel.

[0008] In some embodiments, the demisting assembly includes a first partition, a second partition, and a baffle plate. The first partition and the second partition are parallel to each other and staggered along the axial direction of the air outlet, and are both connected to the inner wall of the housing. The first partition and the inner wall of the housing form an air inlet communication hole, and the second partition and the housing form an air outlet communication hole. The air inlet, the air inlet communication hole, the air outlet communication hole, and the air outlet together form the demisting channel. The baffle plate is disposed between the first partition and the second partition along the axial direction of the air outlet, and both ends of the baffle plate are respectively connected to the first partition and the second partition.

[0009] In some embodiments, the defogging assembly further includes a plurality of first connecting ribs, which are arranged circumferentially along the housing and are respectively connected to the first partition or the second partition and connected to the housing.

[0010] In some embodiments, the defogging assembly further includes a plurality of second connecting ribs, which are arranged circumferentially along the housing and are respectively connected to the baffle plate and the housing.

[0011] In some embodiments, the circumferential sidewall of the housing is further provided with at least one maintenance manhole, which is disposed between the first partition and the second partition and communicates with the interior of the housing. The baffle-type demister also includes at least one manhole cover, which is disposed opposite to the maintenance manhole and connected to the housing for opening or blocking the maintenance manhole.

[0012] In some embodiments, the baffle-type demister further includes a support connected to the housing and configured to support the housing standing on the ground.

[0013] In some embodiments, the side wall of the housing is provided with a water inlet communicating with its interior. The water inlet is located below the second partition. The bottom of the housing is provided with a drain outlet communicating with its interior. The baffle-type demister also includes a drain pipe connected to the support and communicating with the interior of the housing through the drain outlet.

[0014] In some embodiments, the defoaming assembly further includes a liquid collection tank and a liquid guide pipe. The liquid collection tank is disposed between the first partition and the baffle plate, and the interior of the liquid collection tank is connected to the interior of the baffle plate. The liquid guide pipe is connected to the inner wall of the housing, with one end of the liquid guide pipe connected to the interior of the liquid collection tank and the other end disposed opposite to the drain port.

[0015] In some embodiments, the defoaming assembly further includes at least one mounting bracket connected to the liquid guide tube and connected to the inner wall of the housing.

[0016] Compared with the prior art, the beneficial effects of the baffle-type demister provided by this utility model include: the shell is hollow inside, and its side wall has an air inlet and an air outlet connected to the inside, forming an "L"-shaped demister channel. The demister assembly is connected to the shell and is positioned opposite the air outlet, and is built into the demister channel to separate liquid mist, droplets, or foam in the gas flowing through the demister channel. Compared with the prior art, by setting the demister channel with an "L"-shaped path, the high-speed steam flows along the demister channel and first hits the inner wall of the shell, forming some liquid mist, droplets, or foam that are separated from the high-speed steam. Subsequently, the high-speed steam that is not completely separated is further separated after passing through the demister assembly located near the air outlet, achieving a highly efficient separation effect and improving the demister effect. This solves the technical problem in the prior art where the high-speed steam, flowing in a horizontal direction, separates and carries away the droplets that have accumulated near the baffle outlet, resulting in poor demister effect.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] To address the technical problem of poor demisting effect caused by high-speed steam separating and carrying away droplets accumulated near the outlet of the baffle plate 230 after flowing horizontally, this invention provides a baffle plate type demisting device. This device utilizes an "L"-shaped demisting channel, where high-speed steam first impacts the inner wall of the casing 100, forming partial liquid mist, droplets, or foam that separates from the high-speed steam. The remaining high-speed steam that is not completely separated is further separated by the demisting component 200 located near the outlet 120, achieving efficient separation and improving the demisting effect.

[0021] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a baffle plate type demister in one embodiment of the present invention. The baffle plate type demister includes a housing 100 and a demister assembly 200. The housing 100 is hollow inside and has an L-shaped demister channel. The outer wall of the housing 100 has an air inlet 110 and an air outlet 120 that are connected to the demister channel. The demister assembly 200 is disposed opposite to the air outlet 120 and is built into the demister channel to separate liquid mist, droplets or foam in the gas flowing through the demister channel.

[0022] In this device, compared with the prior art, by setting an "L"-shaped demister channel, the high-speed steam flows along the demister channel and first hits the inner wall of the wall shell 100 to form some liquid mist, droplets or foam, which is separated from the high-speed steam. Then, the high-speed steam that is not completely separated is further separated after passing through the demister component 200 set near the outlet 120, achieving a high-efficiency separation effect and improving the demister effect. This can solve the technical problem in the prior art where the high-speed steam flows along the horizontally set flow direction and separates and carries away the droplets that have accumulated near the outlet of the baffle 230 again, resulting in poor demister effect.

[0023] Furthermore, after the high-speed steam enters the interior of the housing 100 through the air inlet 110, it flows axially along the air inlet 110 and impacts the inner wall of the housing 100, which can initially separate some of the liquid mist, droplets or foam in the high-speed steam. Subsequently, the high-speed steam flows along the path in an "L"-shaped demisting channel and undergoes secondary separation through the demisting component 200, achieving efficient separation and demisting effect.

[0024] Furthermore, the shell 100 is a high-pressure sealed tank container that is common and readily available on the market, and will not be described in detail here.

[0025] In this embodiment, as Figure 1 As shown, the air inlet 110 is located on the side wall of the housing 100, and the air outlet 120 is located on the top of the housing 100. The axis of the air outlet is perpendicular to the axis of the air inlet to form a defoaming channel.

[0026] To facilitate the separation of liquid mist, droplets, or foam in the gas and improve the demisting effect, the air inlet 110 is located on the side wall of the housing 100 and is arranged in a horizontal direction, while the air outlet 120 is located on the top of the housing 100 and is arranged in a vertical direction. This allows the air inlet 110 and the air outlet 120 to form an "L"-shaped demisting channel with the interior of the housing 100.

[0027] In one embodiment, please refer to Figure 1 The demisting assembly 200 includes a first partition 210, a second partition 220, and a baffle 230. The first partition 210 and the second partition 220 are parallel to each other and staggered along the axial direction of the air outlet 120, and are both connected to the inner wall of the housing 100. The first partition 210 and the inner wall of the housing 100 enclose each other to form an air inlet communication hole 130, and the second partition 220 and the housing 100 enclose each other to form an air outlet communication hole 140. The air inlet 110, the air inlet communication hole 130, the air outlet communication hole 140, and the air outlet 120 enclose each other to form a demisting channel. The baffle 230 is arranged between the first partition 210 and the second partition 220 along the axial direction of the air outlet 120, and the two ends of the baffle 230 are respectively connected to the first partition 210 and the second partition 220.

[0028] By utilizing the first baffle 210 and the second baffle 220, which are arranged parallel to each other and staggered along the axial direction of the outlet 120 and are both connected to the inner wall of the housing 100, the flow path of high-speed steam inside the housing 100 can be extended, promoting the separation of liquid mist, droplets or foam in the gas, so that the high-speed steam can collide with the inner wall of the housing 100 or the first baffle 210 and the second baffle 220 multiple times.

[0029] Furthermore, the baffle plate 230 here is made of stainless steel or plastic, and parameters such as the plate spacing and baffle angle directly affect the separation effect. For example, increasing the number of baffles (such as using a densely arranged angle steel structure) can improve the capture ability of tiny droplets. The baffle plate 230 is a common and readily available device on the market and is a conventional setting known to those skilled in the art. For reference, please refer to Chinese Utility Model Patent No. CN216320575U, entitled "A Baffle Plate 230 Type Demister and a Demister Device Using the Demister". Further details will not be elaborated here.

[0030] In some embodiments, the baffle 230 can also be a wire mesh, which will not be described in detail here.

[0031] In one embodiment, please refer to Figure 1The defoaming assembly 200 also includes a plurality of first connecting ribs 240, which are arranged along the circumference of the housing 100 and are respectively connected to the first partition 210 or the second partition 220 and connected to the housing 100.

[0032] By providing multiple first connecting ribs 240 in the circumferential direction of the first partition 210 and the second partition 220, the connection strength between the first partition 210 and the second partition 220 and the housing 100 can be increased, thereby increasing the stability of the device operation.

[0033] In one embodiment, please refer to Figure 1 The defoaming assembly 200 also includes a plurality of second connecting ribs 250, which are arranged circumferentially along the housing 100 and are respectively connected to the baffle plate 230 and the housing 100.

[0034] By providing multiple second connecting ribs 250 in the circumferential direction of the baffle plate 230, the connection strength between the baffle plate 230 and the housing 100 can be increased, thereby increasing the stability of the device operation.

[0035] In one embodiment, please refer to Figure 1 The circumferential sidewall of the housing 100 is also provided with at least one maintenance manhole, which is located between the first partition 210 and the second partition 220 and is connected to the interior of the housing 100. The baffle plate type demister also includes at least one manhole cover 300, which is positioned opposite the maintenance manhole and connected to the housing 100 for opening or blocking the maintenance manhole.

[0036] By providing a maintenance manhole on the side wall of the housing 100, it is convenient to clean or repair the interior of the housing 100, thereby improving the stability and safety of the device operation.

[0037] Furthermore, the manhole cover 300 is used to open or block the maintenance manhole. Multiple manhole covers 300 are spaced apart along the circumference of the housing 100. The manhole covers 300 are common and readily available equipment on the market and are a conventional arrangement known to those skilled in the art, so they will not be described in detail here.

[0038] In this embodiment, as Figure 1 As shown, the baffle plate type demister also includes a support 400, which is connected to the housing 100 and is configured to support the housing 100 to stand on the ground.

[0039] By setting a support 400 at the bottom of the housing 100, the housing 100 can be supported to stand vertically on the ground, thereby improving the stability and safety of the device operation.

[0040] In one embodiment, please refer to Figure 1 The side wall of the housing 100 is also provided with a water inlet 150 that communicates with its interior. The water inlet 150 is located below the second partition 220. The bottom of the housing 100 is provided with a drain outlet that communicates with its interior. The baffle plate type demister also includes a drain pipe 500, which is connected to the support 400 and is connected to the interior of the housing 100 through the drain outlet.

[0041] By setting the inlet 150, the baffle plate 230 can be flushed when high-speed steam is introduced, which can wash off the liquid mist, droplets or foam attached to the baffle plate 230. At the same time, the drain pipe 500 can discharge the liquid mist, droplets or foam separated in the housing 100, so as to avoid affecting the defoaming effect of the device.

[0042] Furthermore, the drain outlet is located at the center of the housing 100 to avoid blockage or clogging caused by impurities or sediment. The drain pipe 500 is a common and readily available connecting hose on the market, which is a conventional setting known to those skilled in the art and will not be described in detail here.

[0043] In one embodiment, please refer to Figure 1 The defoaming assembly 200 also includes a liquid collection tank 260 and a liquid guide pipe 270. The liquid collection tank 260 is disposed between the first partition 210 and the baffle 230. The interior of the liquid collection tank 260 is connected to the interior of the baffle 230. The liquid guide pipe 270 is connected to the inner wall of the housing 100. One end of the liquid guide pipe 270 is connected to the interior of the liquid collection tank 260, and the other end is disposed opposite to the drain port.

[0044] By setting up a liquid collection tank 260 and a liquid guide pipe 270, the liquid mist, droplets or foam that are washed down can be collected and discharged to the drain outlet along the liquid guide pipe 270, thus avoiding its impact on the defoaming effect. Furthermore, the fluid guide tube 270 here is a common and readily available connecting hose on the market, which is a conventional setting known to those skilled in the art, and will not be described in detail further.

[0045] In one embodiment, please refer to Figure 1 The defoaming assembly 200 also includes at least one mounting bracket 280, which is connected to the liquid guide tube 270 and to the inner wall of the housing 100.

[0046] By setting the mounting bracket 280, the liquid guide tube 270 can be fixed, thereby improving the stability and safety of the device operation.

[0047] To better understand this utility model, the following is combined with... Figure 1 The technical solution of this utility model is described in detail below: The housing 100 is hollow inside, and its sidewalls have an air inlet 110 and an air outlet 120 that communicate with the interior, forming an "L"-shaped demister channel. A demister assembly 200 is connected to the housing 100 and positioned opposite the air outlet 120, and is built into the demister channel to separate liquid mist, droplets, or foam from the gas flowing through it. Compared to existing technologies, by setting an "L"-shaped demister channel, high-speed steam flowing along the demister channel first impacts the inner wall of the housing 100, forming some liquid mist, droplets, or foam that separates from the high-speed steam. The remaining high-speed steam that is not completely separated is further separated by the demister assembly 200 positioned near the air outlet 120, achieving efficient separation and improving the demister effect.

[0048] In the specific working process of this utility model, after the high-speed steam enters the interior of the housing 100 through the air inlet 110, it flows along the axial direction of the air inlet 110 and impacts the inner wall of the housing 100, which can initially separate some of the liquid mist, droplets or foam in the high-speed steam. Then the high-speed steam flows along the path in an "L"-shaped demisting channel and undergoes secondary separation through the demisting component 200.

[0049] Furthermore, this device employs a novel barrel-type demister, which, compared to traditional demisters, adds an additional inertial collision process between steam and the barrel wall. Before entering the baffle 230, some droplets form a liquid film on the barrel wall due to inertial force and flow down and are collected due to gravity. This reduces the amount of demister material removed by the baffle 230 and improves the demistering effect. The novel barrel-type demister fully utilizes the demister barrel diameter and the height of the straight section. Its steam flow rate adjustment depends on the product of the straight section height and the barrel diameter, changing the traditional method of adjusting the steam flow rate only by the barrel diameter. The novel barrel-type demister has a larger adjustment margin for the steam flow rate and a better match between the equipment and the operating conditions. The steam flow direction is 90° to the flushing water, which effectively avoids the problem of secondary steam carrying flushing water after demistering, thus preventing a decrease in demistering effect.

[0050] This device, through the aforementioned structure, can solve the technical problem in the prior art where high-speed steam, after flowing along a horizontally positioned direction, will separate and carry away the droplets that have accumulated near the outlet of the baffle 230, resulting in poor defoaming effect.

[0051] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
