Since ship fuel mainly consists of distillate fuel oil and residual fuel oil, a large amount of flue gas is generated during combustion, which contains dust, sulfur and nitrogen oxides, etc., which can have a great impact on people's health. Therefore, energy-saving and emission-reduction devices are often used to treat the flue gas and reduce the emission of harmful substances.

[0003] For example, Chinese utility model patent CN216572460U discloses a shipborne energy-saving and emission-reduction treatment device, belonging to the field of marine technology. It includes a spray tank with a gas inlet pipe and a spray inlet pipe connected to a spray pump. The spray pump is connected to a spray outlet pipe with nozzles. The spray tank has a hot water jacket and a gas outlet pipe connected to a heat exchanger. The heat exchanger is connected to an activated carbon box, which is connected to a fan with a vent pipe. The spray tank also has a circulating water tank connected to a heat exchange jacket circulation pump and a heat exchanger circulation pump. The heat exchange jacket circulation pump is connected to the hot water jacket, which is connected to the circulating water tank. The heat exchanger circulation pump is connected to the heat exchanger, which is connected to the circulating water tank. The heat exchanger circulation pump is connected to the heat exchanger, which is connected to the circulating water tank. This utility model uses a circulating spray of alkaline solution to remove sulfur dioxide and nitrogen oxides, and recovers the heat for use as domestic hot water on board, achieving the goal of saving energy and reducing emissions.

They are generally not convenient for double filtration and filter cleaning of flue gas generated by ship fuel, not convenient for waste heat recovery and utilization, and not convenient for reaction purification of flue gas before emission. Therefore, we propose a marine energy-saving and emission-reduction device to solve the problems mentioned above. Utility Model Content

[0028] Please see Figure 1-5 This utility model provides a technical solution: a marine energy-saving and emission-reduction device, comprising a housing 1, a smoke pipe 2, a first filter screen 3, a second filter screen 4, a fixing strip 5, a housing cover 6, a first sealing gasket 7, a limiting strip 8, a heat exchange pipe 9, a second sealing gasket 10, a solenoid valve 11, a water pipe 12, a drain pipe 13, a temperature sensor 14, a controller 15, a nozzle 16, a pump 17, a third sealing gasket 18, a liquid pipe 19, a liquid level sensor 20, and a smoke exhaust pipe 21.

Fixing strip 5, box cover 6, first sealing gasket 7 and limiting strip 8, and the first filter screen 3 and the second filter screen 4 set below it are nested and attached to the inner side of the left end of the box body 1. The inner side of the middle part of the box body 1 is provided with a waste heat recovery structure, which includes a heat exchange pipe 9, a second sealing gasket 10, a solenoid valve 11, a water pipe 12, a drain pipe 13, a temperature sensor 14 and a controller 15.

[0029] To address the problem in existing technologies that make it inconvenient to perform dual filtration and filter removal on flue gas generated from ship fuel, this embodiment employs the following technical solution: Figure 1 , Figure 2 , Figure 3 and Figure 4Firstly, flue gas generated by ship fuel can be introduced into the device through the flue pipe 2, which is fixedly connected to the upper left side of the housing 1. Below the flue pipe 2, a first filter screen 3 and a second filter screen 4 are sequentially arranged and nested with the housing 1. Fixing strips 5, which are fixedly connected to the housing 1, are attached to the lower front ends of the first filter screen 3 and the second filter screen 4. A housing cover 6, which is fixedly connected to the first filter screen 3 and the second filter screen 4, is nested with the housing 1. A first sealing gasket, which is adhered and fixed to the housing 1, is tightly fitted to the outside of the housing cover 6. 7. The limiting strip 8, which is attached to the rear right side of the box cover 6, is connected to the box body 1 in a damped rotational manner. Therefore, it is convenient for the exhaust gas generated by ship fuel to be double filtered by the first filter screen 3 and the second filter screen 4 under the cover 6 and the first sealing gasket 7. After the device has been used for a long time or after use, the limiting strip 8 can be rotated to disconnect the limiting strip 8 from the box cover 6. Then the box cover 6 can be moved backward so that the box cover 6 can drive the first filter screen 3 and the second filter screen 4 out of the box body 1, thereby facilitating the cleaning of the filtered material. Specific Implementation Example 2

[0030] To address the problem of inconvenient waste heat recovery and utilization in existing technologies, this embodiment employs the following technical solution: Figure 1 , Figure 2 , Figure 3 and Figure 4 Because heat exchange tubes 9 are evenly spaced on the inner side of the middle part of the box 1, and the lower left end of the heat exchange tube 9 is connected to the left end of the box 1, and a second sealing gasket 10 is tightly attached to the outer side of the left end of the heat exchange tube 9 and fixed to the box 1, after filtering the flue gas generated by the ship fuel, the flue gas can easily enter the heat exchange tube 9 under the seal of the second sealing gasket 10. The heat exchange tube 9 heats the water in the inner side of the middle part of the box 1, achieving the purpose of waste heat recovery and utilization. The controller 15 installed on the inner side of the upper end of the box 1 can control the temperature sensor 14 installed on the box 1 below the controller 15 to operate and sense the water temperature so that the user can know the water temperature. The controller 15 can also control the solenoid valves 11 fixedly installed on the inner side of the upper end and the inner side of the lower rear end of the box 1 to operate, so that the water pipe 12 and the drain pipe 13 connected to the outside of the solenoid valve 11 are connected to the box 1 for drainage. Specific Implementation Example 3

[0031] To address the problem in existing technologies where it is inconvenient to purify flue gas through reaction before emission, this embodiment employs the following technical solution: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5Since the upper right end of the heat exchange tube 9 is connected to the right end of the housing 1, it facilitates the passage of the flue gas after heat exchange to the inner side of the right end of the housing 1. Because a nozzle 16 threadedly connected to the housing 1 is provided on the upper right side of the heat exchange tube 9, and a liquid passage pipe 19 threadedly connected to the pump 17 is connected to the nozzle 16, the pump 17, which is nested and installed on the inner side of the lower right front end of the housing 1, can be controlled by the controller 15 to operate. This allows the pump 17, under the tight seal of the third sealing gasket 18, to pump the gas from the housing 1... The reaction liquid on the lower right inner side circulates through the liquid pipe 19 to the upper inner side of the chamber 1, and is then sprayed out through the nozzle 16, so that the reaction liquid reacts and purifies the flue gas. Finally, it is discharged through the exhaust pipe 21 connected to the right inner side of the chamber 1. During the flue gas reaction process, the liquid level sensor 20 embedded in the lower right inner side of the chamber 1 can be controlled by the controller 15 to sense the liquid level of the reaction liquid so as to add the reaction liquid and avoid affecting the reaction. All the electrical components mentioned above are existing technologies and will not be described in detail here.
