Description

Technical Field

[0001] This utility model belongs to the technical field of defoaming equipment, and in particular to a composite multi-layer defoaming wire mesh demister. Background Technology

[0002] Wire mesh demisters are a type of high-efficiency gas-liquid separation device. However, most demister wire meshes are currently set horizontally, which results in poor droplet falling of the demistered liquid and affects the subsequent demistering effect.

[0003] A search revealed a Chinese patent document (authorization announcement number CN218077188U) entitled "A Composite Multilayer Demisting Wire Mesh Demister," relating to the field of wire mesh demister technology. The demister body includes a wire mesh demister body with two sets of flaps at its bottom. A rotating shaft passes through the center of each flap, and the flaps and the rotating shaft are connected. A first and second flow guide hood are provided between the flaps and the demister body, with the second flow guide hood located inside the first flow guide hood. Support frames are provided at the bottom of the first and second flow guide hoods. During the dripping process, some water droplets flow down the surfaces of the first and second flow guide hoods onto the flaps, while others drip directly onto the flaps. Finally, as the flaps rotate, the water droplets flow to the flow guide plate. Because the gas exerts force on one side of the flaps from bottom to top, the water droplets drip onto the other side of the flaps, preventing them from interfering with each other and ensuring that the water does not drip into the airflow. The water is ultimately discharged through the outlet. The demister's wire mesh is set horizontally, which makes the droplets formed by demistering fall poorly, affecting the subsequent demistering effect. Utility Model Content

[0004] The purpose of this invention is to provide a composite multi-layer defoaming wire mesh demister to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a composite multi-layer demisting wire mesh demister, comprising:

[0006] The demist box has multiple layers of inclined assembly frames that can be detachably connected to its inner wall. The inner wall of the assembly frames is connected to wire mesh, and multiple wire meshes are used for composite demisting. The mesh count of the multiple wire meshes increases sequentially from bottom to top.

[0007] Multiple vibration assemblies are installed on the outer wall of the demister box for vibration demister removal. The vibration assembly includes two hollow plates fixedly connected to the demister box and a movable plate set in the inner cavity of the hollow plate. A rotating rod is rotatably connected between the two movable plates. Multiple eccentric wheels for vibrating the demister box are connected to the outer periphery of the rotating rod. A rotary motor that provides power to the rotating rod is installed on the side of one of the movable plates.

[0008] A spring with a damper connects the movable plate and the demister box.

[0009] As a preferred embodiment, the side of the demister is connected to an inclined air inlet pipe, and the air inlet pipe is located below multiple assembly frames.

[0010] As a preferred embodiment, both the top and bottom of the demister are connected to ventilation ducts.

[0011] As a preferred embodiment, the upper vent is connected to an air outlet pipe, and the lower vent is connected to a water outlet pipe.

[0012] As a preferred embodiment, the inner wall of the demister is connected to a plurality of inclined baffles corresponding to the assembly frame, and the width of the inclined baffles is smaller than the width of the assembly frame.

[0013] As a preferred embodiment, the side of the demister is rotatably connected to an inspection door, and the side of the inspection door is fitted with a viewing window for easy observation.

[0014] As a preferred embodiment, a linear motor is installed at the bottom of the assembly frame, and the moving part of the linear motor is connected to a cleaning brush for cleaning the wire mesh.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] This composite multi-layer defogging wire mesh demister has both the assembly frame and the wire mesh in an inclined state, which allows the formed droplets to move downwards better with gravity. The rotary motor drives the rotating rod to rotate, which in turn drives the eccentric wheel to rotate, intermittently hitting the demister box, improving the degree and thoroughness of droplet falling. The linear motor drives the cleaning brush to move back and forth, which can process the wire mesh and improve the treatment effect of droplets.

[0017] The composite multi-layer defogging wire mesh demister is equipped with an inclined baffle that can achieve a certain degree of liquid accumulation, allowing the droplets to leak from the gap between the inclined baffle and the demister box and move along the assembly frame, reducing the impact on the wire mesh below.

[0018] This composite multi-layer defoaming wire mesh demister can improve the droplet falling effect of the wire mesh in multiple ways, reducing the impact of droplets on subsequent defoaming. Attached Figure Description

[0028] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0029] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0030] The connection method can adopt existing methods such as bonding, welding, bolting, etc., depending on the actual needs. Techniques, methods and equipment known to those skilled in the art may not be discussed in detail. However, where appropriate, the techniques, methods and equipment should be regarded as part of the specification. The proportions of the components in the drawings are for reference only and can be adjusted to a certain extent according to the actual use.

[0031] Please see Figures 1 to 4 As shown, a composite multi-layer demisting wire mesh demister, in this embodiment, includes:

[0032] The demister box 1 has multiple layers of inclined assembly frames 2 detachably connected to its inner wall. The lowest end of the assembly frame 2 does not contact the demister box 1 to allow for liquid leakage and prevent droplet accumulation. However, the gap needs to be designed to be very small to prevent most of the gas from flowing through this area. However, the inclined baffle 9 will also block the air to a large extent, allowing the air to flow from the top of the wire mesh 3. The inner wall of the assembly frame 2 is connected to the wire mesh 3. Multiple wire meshes 3 perform composite demistering. The mesh count of the multiple wire meshes 3 increases sequentially from bottom to top. The gas enters the demister box 1 through the air inlet pipe 5 and is then demistered by the wire meshes 3. As the gas continues to flow upward, it can perform composite demistering on multiple wire meshes 3.

[0033] A linear motor 11 is installed at the bottom of the assembly frame 2. The moving part of the linear motor 11 is connected to a cleaning brush 12 for cleaning the wire mesh 3. The linear motor 11 drives the cleaning brush 12 to move back and forth, which can process the wire mesh 3 and improve the treatment effect of droplets.

[0034] Multiple vibration assemblies 4 are installed on the outer wall of the demister box 1 for vibration demisting. The vibration assembly 4 includes two hollow plates 41 fixedly connected to the demister box 1 and a movable plate 42 disposed in the inner cavity of the hollow plate 41. A rotating rod 43 is rotatably connected between the two movable plates 42. Multiple eccentric wheels 44 for vibrating the demister box 1 are connected to the outer periphery of the rotating rod 43. A rotary motor 45 that provides power to the rotating rod 43 is installed on the side of one of the movable plates 42. A spring 46 with a damper is connected between the movable plate 42 and the demister box 1. During the demisting process, droplets will form on the wire mesh 3. The larger droplets will tilt and move downward along the wire mesh 3. The rotary motor 45 drives the rotating rod 43 to rotate, which in turn drives the eccentric wheels 44 to rotate, intermittently striking the demister box 1 to assist the droplets in falling and sliding down.

[0035] To meet usage requirements, the side of the demister box 1 is connected to an inclined air inlet pipe 5, and the air inlet pipe 5 is located below multiple assembly frames 2. The top and bottom of the demister box 1 are connected to air ducts 6. The upper air duct 6 is connected to an air outlet pipe 7, and the lower air duct 6 is connected to a water outlet pipe 8.

[0036] The inner wall of the demister box 1 is connected to multiple inclined baffles 9 corresponding to the assembly frame 2. The width of the inclined baffles 9 is smaller than the width of the assembly frame 2. The inclined baffles 9 can achieve a certain degree of liquid accumulation, so that the liquid droplets leak from the gap between the inclined baffles 9 and the demister box 1 and continue to move down along the assembly frame 2, and finally exit from the water outlet pipe 8.

[0037] The air inlet pipe 5, water outlet pipe 8, and air outlet pipe 7 are all designed as deformable corrugated pipes to achieve vibration.

[0038] The side of the demister box 1 is rotatably connected to an inspection door 10, and the side of the inspection door 10 is fitted with a viewing window for easy observation.

[0039] Since the linear motor 11 is located inside the demister box 1, it needs to be designed to be heat-resistant, waterproof, and corrosion-resistant to ensure safety and continuous operation.

[0040] Linear motor 11 and rotary motor 45 are both conventional instruments. Their working principles, dimensions and models are irrelevant to the problems solved by this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0041] Working principle

[0042] In this composite multi-layer demisting wire mesh demister, gas enters the demister box 1 through the air inlet pipe 5, and is then demisted by the wire mesh 3. When the gas continues to flow upward, it can perform composite demisting on multiple wire meshes 3.

[0043] During the defoaming process, droplets will form on the wire mesh 3. Larger droplets will tilt and move downwards along the wire mesh 3. The rotary motor 45 drives the rotating rod 43 to rotate, which in turn drives the eccentric wheel 44 to rotate, intermittently hitting the defoaming box 1 to assist the droplets in falling and sliding down. The linear motor 11 drives the cleaning brush 12 to move back and forth, which can process the wire mesh 3 and improve the treatment effect of droplets. After the droplets move down to the defoaming box 1, the inclined baffle 9 can achieve a certain degree of liquid accumulation, so that the droplets leak from the gap between the inclined baffle 9 and the defoaming box 1 and continue to move downwards along the assembly frame 2, and finally exit from the water outlet pipe 8.
