Description

Technical Field

[0001] This utility model relates to the field of corrugated plate technology, and in particular to a corrugated plate defoaming device suitable for high air velocity operation. Background Technology

[0002] According to Chinese Patent No. CN216499395U, a corrugated packing for a calendered orifice plate relates to the field of petrochemical equipment technology. It includes a steel hoop, within which are arranged a group of distribution plates and a group of distribution plates. The group of distribution plates includes an a-rolled plate, and the group of distribution plates includes a b-rolled plate. Distribution holes are arrayed on the surfaces of the a-rolled plate and the b-rolled plate, and burrs are provided on their sides. Because the top surface of the equipment has an arc, liquid flows into the equipment along the inclined surface and flows out quickly through the inclined distribution holes, improving the equipment's working efficiency. The burrs on the calendered orifice plate do not need to be treated, and arranging adjacent calendered plates in sequence increases the stability of the equipment.

[0003] The above-mentioned documents and existing technologies have the following problems: Under high gas velocity operating conditions, the top surface of the existing corrugated plates is prone to fogging residue, resulting in low gas-liquid separation efficiency, inability to actively perform defoaming operation, and difficulty in stable operation of the corrugated plates under high gas velocity. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a corrugated plate demister suitable for high-air-velocity operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a corrugated plate defoaming device suitable for high air velocity operation, comprising a corrugated assembly, a fixed frame provided on the bottom surface of the corrugated assembly, an installation rod provided on the inner wall of the fixed frame, a bearing seat provided on the surface of the installation rod, a rotating shaft provided on the surface of the bearing seat, a fixed sleeve provided on the surface of the rotating shaft, a scraping plate provided on the surface of the fixed sleeve, a driving plate provided on the top surface of the scraping plate, and a strip groove formed on the surface of the driving plate.

[0006] Preferably, the corrugated assembly includes a support frame and corrugated plates, and the inner wall of the support frame is provided with multiple corrugated plates.

[0007] Preferably, the fixing frame is disposed on the bottom surface of the support frame, and the top surface of the fixing frame is welded to the bottom surface of the support frame.

[0008] Preferably, the central axis of the bearing housing is the same as the central axis of the support frame, and the bearing housing is connected to the corrugated plate through the bearing.

[0009] Preferably, the scraper has a triangular cross-sectional shape, and the bottom surface of the scraper is in contact with the top surface of the corrugated plate.

[0010] Preferably, the scraping plate is rotatably connected to the bearing seat via a rotating shaft, and the position of the scraping plate is adapted to the support frame.

[0011] Preferably, the strip grooves are arranged at an inclined angle on the surface of the drive plate, and the strip grooves are arranged in a linear array on the surface of the drive plate.

[0012] Beneficial effects

[0013] In this invention, a drive plate, strip grooves, a scraper plate, and a rotating shaft are used. When liquid falls onto the surface of the drive plate, due to the inclined design of the strip grooves, the liquid flow direction makes an angle with the circumferential direction of the drive plate. According to the momentum theorem, when the liquid changes its flow direction, it will exert a force on the groove wall. This force can be decomposed into a normal force perpendicular to the groove wall and a tangential force along the tangential direction of the groove wall. The tangential forces generated by multiple strip grooves form a resultant force. The resultant force does not pass through the center of the rotating shaft, thus generating an eccentric force. This eccentric force drives the drive plate and the scraper plate to rotate through the rotating shaft. The scraper plate has a triangular cross-section, and during its rotation, it can perform a comprehensive and continuous scraping action on the top surface of the corrugated plate, effectively solving the problem of mist adhesion and residue on the top surface of the corrugated plate. It actively scrapes off the mist, improves the gas-liquid separation efficiency, and enables the corrugated plate to operate stably at high gas velocities. Attached Figure Description

[0020] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0023] Reference Figure 1-4 A corrugated plate demister suitable for high-velocity operation includes a corrugated assembly 1. The corrugated assembly 1 includes a support frame 101 and corrugated plates 102. The support frame 101 serves as the support structure for the entire corrugated assembly 1, providing installation space for multiple corrugated plates 102 to maintain a stable arrangement and ensure the overall structural stability of the demister. Multiple corrugated plates 102 are provided on the inner wall of the support frame 101. The corrugated plates 102 are the main working components for demistering. When a high-velocity airflow passes through, their corrugated structure causes the mist in the airflow to collide and adhere to the surface of the corrugated plates 102, initially achieving gas-liquid separation. A fixing frame 2 is provided on the bottom surface of the corrugated assembly 1, and the fixing frame 2 is located on the bottom surface of the support frame 101. The top surface of the fixed frame 2 is welded to the bottom surface of the support frame 101. The fixed frame 2 is stably connected to the support frame 101 by welding, providing an installation base for components such as the mounting rod 3, and ensuring the structural stability of the entire defogging device. The inner wall of the fixed frame 2 is provided with the mounting rod 3, which is used to support the bearing seat 4, so that the bearing seat 4 can be fixed in a suitable position, providing support for the installation and rotation of the rotating shaft 5. The surface of the mounting rod 3 is provided with the bearing seat 4. The central axis of the bearing seat 4 is the same as the central axis of the support frame 101, and the bearing seat 4 is connected to the corrugated plate 102 through. The bearing seat 4 provides support and positioning for the rotating shaft 5, so that the rotating shaft 5 can rotate smoothly, while ensuring that the rotation center of the rotating shaft 5 is consistent with the center of the entire device.

[0024] A rotating shaft 5 is provided on the surface of the bearing housing 4. The rotating shaft 5 rotates under the support of the bearing housing 4, serving as a key component for power transmission. It drives the scraper plate 7 to rotate around the shaft, thus scraping away the mist on the top surface of the corrugated plate 102. A fixing sleeve 6 is provided on the surface of the rotating shaft 5 to fix the scraper plate 7, ensuring that the scraper plate 7 rotates synchronously with the rotating shaft 5. This allows the scraper plate 7 to stably scrape the corrugated plate 102 during rotation. The scraper plate 7 has a triangular cross-sectional shape, with its bottom surface in contact with the top surface of the corrugated plate 102. The scraper plate 7 is rotatably connected to the bearing housing 4 via the rotating shaft 5, and its position is adapted to the support frame 101. The rotating mechanism thoroughly and continuously scrapes away the mist adhering to the top surface of the corrugated plate 102, solving the problem of mist residue and improving gas-liquid separation efficiency. The top surface of the scraper plate 7 is equipped with a drive plate 8. When the liquid falls into the strip groove 9, the interaction between the liquid flow and the groove wall generates an eccentric force, driving itself and the connected scraper plate 7 to rotate, providing rotational power for the scraper plate 7. The drive plate 8 has strip grooves 9 on its surface, which are set at an inclined angle and arranged in a linear array on the surface of the drive plate 8. The strip grooves 9 guide the liquid flow, so that the liquid generates a tangential force on the groove wall according to the momentum theorem during the flow. Multiple tangential forces form a resultant force to generate an eccentric force, which is the key structure for generating the driving rotational power.

[0025] A high-velocity airflow containing mist passes through corrugated plates 102 supported by a support frame 101. The mist collides with and adheres to the surface of the corrugated plates 102, initially achieving gas-liquid separation. However, mist easily remains on the top surface of the corrugated plates 102. At this time, the liquid collected from above falls into the inclined and linearly arrayed strip grooves 9 on the surface of the drive plate 8. Because there is an angle between the liquid flow direction and the circumferential direction of the drive plate 8, according to the momentum theorem, the liquid generates a tangential force on the groove wall. Multiple tangential forces form a resultant force that generates an eccentric force. This eccentric force generates a torque on the rotating shaft 5, driving the drive plate 8 to rotate. This causes the rotating shaft 5 connected to it and the scraper 7 fixed on the rotating shaft 5 to rotate around the shaft. The scraper 7 has a triangular cross-section, with its bottom surface in contact with the top surface of the corrugated plates 102. During its rotation, it comprehensively and continuously scrapes away the mist adhering to the top surface of the corrugated plates 102, thereby solving the problem of mist residue, improving the gas-liquid separation efficiency, and ensuring the stable operation of the corrugated plates 102 at high air velocities. Specific Implementation Example 2:

[0027] A corrugated plate defogging device suitable for high air velocity operation, based on the basic structure in Specific Embodiment 1, further discloses the following: the triangular scraper 7 can be replaced with a flexible scraper with elasticity, such as rubber material, which can better conform to the fine undulations of the corrugated plate 102 surface, further improve the scraping effect, and reduce mist residue.

[0028] In summary:

[0029] 1. The system employs a drive plate 8, strip grooves 9, scraper plate 7, and rotating shaft 5. When liquid falls onto the surface of the drive plate 8, due to the inclined design of the strip grooves 9, the liquid flow direction forms an angle with the circumferential direction of the drive plate 8. According to the momentum theorem, the liquid will exert a force on the groove wall when it changes its flow direction. This force can be decomposed into a normal force perpendicular to the groove wall and a tangential force along the tangential direction of the groove wall. The tangential forces generated by multiple strip grooves 9 form a resultant force. The resultant force does not pass through the center of the rotating shaft 5, thus generating an eccentric force. This eccentric force drives the drive plate 8 and scraper plate 7 to rotate through the rotating shaft 5. The cross-section of the scraper plate 7 is triangular. During its rotation, it can perform a comprehensive and continuous scraping action on the top surface of the corrugated plate 102, effectively solving the problem of mist adhesion and residue on the top surface of the corrugated plate 102. It actively scrapes off the mist, improves the gas-liquid separation efficiency, and enables the corrugated plate 102 to operate stably at high gas velocities.
