Description

Technical Field

[0001] This utility model relates to the field of ship exhaust gas treatment technology, and specifically to a ship exhaust gas treatment device. Background Technology

[0002] During ship operation, a significant amount of exhaust gas is emitted. If not effectively treated, this exhaust gas can pollute the atmospheric environment. Therefore, exhaust gas treatment devices are needed to effectively treat the exhaust gas. For example, patent document CN220257680U discloses a ship exhaust gas treatment device. This device uses a turbine, which rotates when the exhaust gas flows through it. The turbine drives a rotating shaft, which in turn drives a cleaning brush. The cleaning brush cleans the dust adhering to the filter plate surface, reducing the accumulation of dust on the filter plate surface and preventing clogging of the device. This indirectly improves the filtration and purification effect of the device on the exhaust gas emitted by the ship's main engine.

[0003] However, when the above device is in use, the gas flows in a fixed direction after entering the treatment equipment, which prevents it from making large-scale contact filtration with the filter plate surface, resulting in low utilization of the filter plate and reduced filtration effect of the exhaust gas. Utility Model Content

[0004] In view of the problems existing in the above-mentioned ship exhaust gas treatment equipment, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a ship exhaust gas treatment device that solves the problem that the exhaust gas cannot be effectively purified due to the small contact area between the exhaust gas and the filter plate surface during existing ship exhaust gas treatment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A ship exhaust gas treatment device includes an air inlet hood, an air outlet hood, and a filter hood, wherein the filter hood is disposed between the air inlet hood and the air outlet hood, and filter plates are fixedly provided on both sides of the inner wall of the filter hood. A drive motor is fixedly installed on the outer wall of the filter cover. The output shaft of the drive motor passes through the filter cover and is fixedly installed with a support shaft. Multiple sets of connecting components are fixedly installed on the shaft wall of the support shaft, which are evenly distributed along the axis. Each set of connecting components includes multiple spaced connecting rods. The ends of multiple connecting rods on the same side are jointly fixed with a spoiler.

[0007] Preferably, the filter cover is fixedly provided with a connecting ring on the side close to the air inlet cover and the air outlet cover, and two adjacent connecting rings are in contact with each other and are threaded with a plurality of spaced connecting bolts.

[0008] Preferably, both the air inlet hood and the air outlet hood are arranged in a bucket shape, and the air outlet of the air outlet hood is connected to an external fan.

[0009] Preferably, the end of the support shaft away from the drive motor is rotatably engaged with the other side of the filter cover.

[0010] Furthermore, the longitudinal sections of all of the aforementioned spoilers are L-shaped.

[0011] Preferably, the end of the spoiler away from the support shaft is provided with a guide slope, which is used to separate the exhaust gas.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model, through the provided air inlet hood, air outlet hood, filter hood, filter plate, motor, support shaft, connecting rod and baffle, can cause multiple baffles to rotate and disturb the exhaust gas when the exhaust gas flows through the equipment for filtration, so that the exhaust gas diffuses in the filter hood and makes full contact with the surface of the filter plate, avoiding the occurrence of filtration blind spots, and improving the filtration effect at the same time. 2. This utility model, with its filter cover, air inlet cover, air outlet cover, connecting ring, and connecting ring, allows for easy disassembly of the filter cover and quick cleaning of the filter plate, thus improving the multi-functionality of the equipment.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model discloses a ship exhaust gas treatment device.

[0018] This utility model provides, for example Figure 1-3 The ship exhaust gas treatment equipment shown includes an air inlet hood 1, an air outlet hood 2 and a filter hood 3. The filter hood 3 is located between the air inlet hood 1 and the air outlet hood 2. Both the air inlet hood 1 and the air outlet hood 2 are arranged in a bucket shape. The air outlet of the air outlet hood 2 is connected to an external fan. Filter plates 4 are fixedly provided on both sides of the inner wall of the filter hood 3. A drive motor 5 is fixedly installed on the outer wall of the filter cover 3. The output shaft end of the drive motor 5 passes through the filter cover 3 and is fixedly installed with a support shaft 10. The end of the support shaft 10 away from the drive motor 5 is rotatably engaged with the other side of the filter cover 3. Multiple sets of connecting components are fixedly installed on the shaft wall of the support shaft 10, which are evenly distributed along the axis. Each set of connecting components includes multiple connecting rods 6 spaced apart. The ends of multiple connecting rods 6 on the same side are jointly fixed with a baffle 7. The end of the baffle 7 away from the support shaft 10 is provided with a guide slope 11, which is used to separate the exhaust gas. The longitudinal sections of multiple baffles 7 are all L-shaped.

[0019] To facilitate easy disassembly of the filter cover and quick cleaning of the filter plate, such as... Figure 1-2 As shown, the filter cover 3 is fixedly provided with a connecting ring 8 on the side close to the air inlet cover 1 and the air outlet cover 2. Two adjacent connecting rings 8 are in contact and fitted, and multiple connecting bolts 9 are threaded and spaced apart.

[0020] Working principle: Connect the air outlet of the exhaust hood 2 to the external fan, start the external fan and the drive motor 5 on the outer wall of the filter cover 3. The external fan generates negative pressure, and the ship exhaust gas is sucked into the funnel-shaped air intake hood 1 under the action of negative pressure. The funnel-shaped structure of the air intake hood 1 can expand the air intake range and guide the exhaust gas to enter the filter cover 3 stably. The output shaft of the drive motor 5 drives the support shaft 10 to rotate. The end of the support shaft 10 away from the drive motor 5 is rotated and engaged with the other side of the filter cover 3 to ensure the stable operation of the support shaft 10. When the support shaft 10 rotates, its shaft wall drives multiple baffles 7 to rotate synchronously through multiple sets of connecting components (each set contains multiple spaced connecting rods 6). The baffles 7 have an L-shaped longitudinal section and a guide slope 11 is provided at the end away from the support shaft 10. During the rotation, the guide slope 11 divides the exhaust gas entering the filter cover 3. The L-shaped structure further disturbs the exhaust gas, breaks the fixed flow direction of the exhaust gas, and promotes the exhaust gas to diffuse fully in the filter cover 3. The diffused exhaust gas comes into full contact with the filter plates 4 fixed on both sides of the inner wall of the filter hood 3. The filter plates 4 filter and purify the pollutants in the exhaust gas. The purified exhaust gas continues to flow towards the exhaust hood 2. After being collected by the bucket-shaped exhaust hood 2, it is extracted by the external fan, thus completing the process of treating ship exhaust gas. When the filter plate 4 needs to be cleaned, unscrew the connecting bolts 9 on the connecting rings 8 between the filter cover 3 and the air inlet cover 1 and the air outlet cover 2, separate the filter cover 3 from the air inlet cover 1 and the air outlet cover 2, and then directly clean or replace the filter plate 4 inside the filter cover 3. After cleaning, reassemble and tighten the connecting bolts 9.

[0021] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
