[0002] Internal combustion engines are widely used, including various types of transportation vehicles (cars, tractors and internal combustion locomotives, etc.) on the ground, machinery in mining, construction and engineering, and main and auxiliary engines for inland and offshore ships. When working, internal combustion engines will emit air pollutants due to incomplete combustion of carbon-containing fuels. The most important emissions are carbon dioxide, water vapor and some carbon black particles. They also emit carbon monoxide, nitrogen oxides, sulfides (mainly sulfur dioxide) and some unburned hydrocarbons.

[0003] Although the existing internal combustion engine exhaust gas filtering device can filter most of the exhaust gas generated by the internal combustion engine, and the exhaust gas purifier can be used to perform secondary combustion on the exhaust gas in the internal combustion engine, the content of harmful substances discharged will be greatly reduced. However, there is still some exhaust gas that cannot be filtered in the gas released after filtering and purification by the existing filtering device, and the purification and filtering efficiency is low. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0018] A carbon dioxide capture device for an internal combustion engine, such as Figure 1-Figure 4 As shown, it includes a bracket 1, a filter barrel 2, an internal combustion engine exhaust pipe 3, a drain port 4, an air pipe 5, an air valve 8, a cylinder 9, an air outlet 10, a filter module 11 and a heater 12. The right part of the bracket 1 is fixedly connected to the filter barrel 2, the right side of the filter barrel 2 is fixedly connected to the internal combustion engine exhaust pipe 3, the internal combustion engine exhaust pipe 3 is inserted into the filter barrel 2, the filter barrel 2 is filled with water, the water level is higher than the pipe mouth of the internal combustion engine exhaust pipe 3, the bottom of the filter barrel 2 is provided with a drain port 4, the upper part of the bracket 1 is fixedly connected to the cylinder 9, the air pipe 5 is connected between the top of the filter barrel 2 and the right side of the cylinder 9, the heater 12 is fixedly connected to the left front side of the cylinder 9, the filter module 11 is fixedly connected inside the cylinder 9, the air outlet 10 is fixedly connected to the left side of the cylinder 9, and the air valve 8 is fixedly connected to the middle of the air pipe 5.

[0019] Initially, the air valve 8 is in an open state. When the internal combustion engine discharges the exhaust gas from the internal combustion engine exhaust pipe 3 into the filter barrel 2, the exhaust gas first enters the water in the filter barrel 2. The water can filter most of the harmful gases and particulate matter in the exhaust gas. After the filtered exhaust gas is discharged from the water, it enters the cylinder 9 along the air pipe 5. The hydroxide solvent in the filter module 11 absorbs the carbon dioxide in the exhaust gas, selectively removes the acidic carbon dioxide from the exhaust gas and forms weak compounds, while other impurities in the exhaust gas will be isolated and accumulated on the right side of the filter module 11. When the filter module 11 reaches a saturated state, the air valve 8 is closed after the internal combustion engine is turned off to prevent over-exhaustion. The exhaust gas in the filter barrel 2 enters the cylinder 9 and interferes with the subsequent process. The heater 12 is started to heat the filter module 11. The weak compounds and carbon dioxide on the filter module 11 are released by heating, and the carbon dioxide is discharged from the outlet 10. The air valve 8 is opened, and the internal combustion engine is started to capture carbon dioxide again. In this way, harmful gases in the exhaust gas can be filtered out, and clean carbon dioxide is finally discharged, thereby improving the exhaust gas purification efficiency of the device. If the water in the filter barrel 2 needs to be replaced, the drain port 4 is opened, the water in the filter barrel 2 is discharged from the drain port 4, and then clean water is injected from the drain port 4.

[0020] The filter plate 6 is also included, and the filter plate 6 is fixedly connected to the filter barrel 2, and the filter plate 6 is higher than the exhaust pipe 3 of the internal combustion engine. When the exhaust gas is discharged from the water in the filter barrel 2, there is still a small part of harmful gas and particulate matter in the exhaust gas that is not filtered by the water. The filter plate 6 can filter the remaining harmful gas and particulate matter, so that most of the gas entering the cylinder 9 is carbon dioxide, further improving the filtering efficiency of the device.

[0021] A water baffle 7 is also included, and the filter barrel 2 is fixedly connected with the water baffle 7, and the water baffle 7 is located between the filter plate 6 and the exhaust pipe 3 of the internal combustion engine. When the exhaust gas is filtered out of the water in the filter barrel 2, bubbles will be generated, and the water baffle 7 can block the splashing water caused by the bursting of the bubbles, prevent water from entering the filter plate 6, prevent the filter plate 6 from being contaminated, and keep the filtering efficiency of the filter plate 6 unchanged.

[0022] It also includes a square shell 13, a collecting box 14, a motor 15, a winding wheel 16, a wire 17, a scraper 18, a guide rod 19 and a coil spring 20. The square shell 13 is fixedly connected to the left upper side of the cylinder 9, and the collecting box 14 is fixedly connected to the left lower side of the cylinder 9. The square shell 13 and the collecting box 14 are both connected to the cylinder 9. The winding wheel 16 is rotatably connected to the top of the square shell 13. The motor 15 is installed on the top of the square shell 13. The output shaft of the motor 15 is fixedly connected to the winding wheel 16. The winding wheel 16 is wound with a wire 17. Two guide rods 19 are fixedly connected between the inside of the square shell 13 and the inside of the collecting box 14. A scraper 18 is slidably connected between the two guide rods 19. Two coil springs 20 are fixedly connected between the square shell 13 and the scraper 18, and the lower end of the wire 17 is fixedly connected to the scraper 18.

[0023] Initially, the two coil springs 20 are in a contracted state, the wire 17 is in a taut state, and the scraper 18 is located at the top edge of the filter module 11. After the internal combustion engine is turned off, the motor 15 is started, and the output shaft of the motor 15 rotates counterclockwise to drive the winding wheel 16 to rotate counterclockwise. The winding wheel 16 rotates counterclockwise to relax the wire 17, so that the two coil springs 20 are restored to their original state and the scraper 18 moves downward along the guide rod 19. The scraper 18 moves downward to contact the right side of the filter module 11, and the impurities on the right side of the filter module 11 are scraped into the collection box 14. When the scraper 18 reaches the maximum drop, the motor 15 is started again and The motor 15 is reversed, and the output shaft of the motor 15 rotates clockwise to drive the winding wheel 16 to rotate clockwise. The winding wheel 16 rotates clockwise to wind the wire 17 back onto the winding wheel 16. The wire 17 drives the scraper 18 to move upward along the guide rod 19 so that both coil springs 20 are compressed, thereby completing the removal of impurities from the filter module 11. A large amount of impurities accumulated on the right side of the filter module 11 will block the filter module 11 and make the filtering effect of the filter module 11 worse. The scraper 18 can clean the filter module 11 and remove the impurities on the right side of the filter module 11 to ensure that the filtering effect of the filter module 11 remains unchanged.

[0024] The movable door 21 and the door stopper 22 are also included. The movable door 21 is rotatably connected to the right side of the collection box 14, and the door stopper 22 is rotatably connected to the right side of the collection box 14. When it is necessary to clean the impurities in the collection box 14, the door stopper 22 is rotated so that the tip of the door stopper 22 faces upward, and the movable door 21 is opened. After the impurities in the collection box 14 are cleaned, the movable door 21 is closed, and the door stopper 22 is rotated again so that the tip of the door stopper 22 faces downward to prevent the movable door 21 from automatically opening and causing impurities to fall out of the collection box 14 and pollute the environment.

[0025] Forty-nine small holes are evenly formed on the water baffle 7. After the waste gas is filtered and discharged from the water, the remaining waste gas can enter the gas delivery pipe 5 through the small holes on the water baffle 7.

[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
