Description

Technical Field

[0001] The present invention relates to the technical field of tail exhaust dehumidification, and in particular to a device for removing moisture from tail exhaust of a hydrogen fuel cell vehicle. Background Art

[0002] With the increasing global awareness of environmental protection and the development of new energy vehicle technology, hydrogen fuel cell vehicles have attracted widespread attention due to their zero emissions and high efficiency. During the operation of hydrogen fuel cell vehicles, the only byproduct of the electrochemical reaction is water, which will be discharged out of the vehicle with the tail gas. However, directly discharging tail gas containing a large amount of water may not only affect the rear view of the vehicle, but also cause the road to be slippery due to condensation of water droplets, increasing the risk of traffic accidents. Therefore, effectively removing water from the tail gas has become an indispensable part of the design of hydrogen fuel cell vehicles.

[0003] In the prior art, the method for removing moisture from tail gas of hydrogen fuel cell vehicles mainly relies on the principle of physical interception, such as setting up structures such as baffles, and controlling the contact between tail gas and baffles to make moisture adhere to the baffles, thereby achieving preliminary separation of moisture. Although this traditional method can reduce the moisture content of tail gas to a certain extent, its effect is limited, especially in the case of high humidity or low temperature, the moisture removal efficiency is significantly reduced, and it is difficult to meet the actual application requirements.

[0004] In order to solve the above problems, we proposed a tail exhaust moisture removal device for hydrogen fuel cell vehicles. This tail exhaust moisture removal device uses a condensation chamber to condense most of the moisture in the tail exhaust into liquid and separate it by cooling, and then further captures the remaining tiny water droplets in the gas through a multi-layer interception net. The moisture in the tail exhaust is removed by combining condensation interception and physical interception, which can greatly improve the effect of removing moisture from the tail exhaust of hydrogen fuel cell vehicles, ensuring driving safety while also reducing the impact on the environment. Summary of the invention

However, the present invention may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

[0033] Embodiment 1: A device for removing moisture from tail gas of a hydrogen fuel cell vehicle, such as Figure 1-Figure 6As shown, it includes a dewatering tank 1, an air inlet pipe 2, an air outlet pipe 3, a protective shell 301, a condensing chamber 4, a refrigeration pipe 5, a collecting box 51, an air guide frame 6, a first motor 7, a dewatering cylinder 8, a guide plate 9, an intercepting net 10 and a dewatering component.

The rear part of the dewatering tank 1 is fixedly connected with the condensing chamber 4. The condensing chamber 4 is fixedly connected with equidistantly distributed refrigeration pipes 5. The lower side of the dewatering tank 1 is connected with the collecting box 51. The lower side of the condensing chamber 4 has equidistantly distributed refrigeration pipes 5. The circular hole is used to guide the condensed water into the collection box 51, the front side of the condensing chamber 4 is fixedly connected to an air guide frame 6, the front side of the dewatering tank 1 is fixedly connected to a first motor 7, the output shaft of the first motor 7 is fixedly connected to a dewatering cylinder 8, the dewatering cylinder 8 is located in the front part of the dewatering tank 1, the rear side of the dewatering cylinder 8 is connected to the front side of the air guide frame 6 and is rotatably connected, the dewatering cylinder 8 is provided with equidistantly distributed strip holes for discharging water, an interception net 10 is fixedly connected in the dewatering cylinder 8, two left-right symmetrical guide plates 9 are fixedly connected to the front part of the dewatering tank 1, the guide plates 9 are arc-shaped, and the guide plates 9 surround the left and right sides of the dewatering cylinder 8, and the condensing chamber 4 is provided with a dewatering component for scraping water droplets off the surface of the refrigeration tube 5.

[0034] When using the device, the tail exhaust of the automobile is introduced into the dewatering tank 1 through the air intake pipe 2, the tail exhaust in the dewatering tank 1 is transported from the back to the front and enters the condensing chamber 4, the condensing chamber 4 is cooled by the refrigeration pipe 5, most of the water in the tail exhaust is condensed into liquid by cooling and stays in the condensing chamber 4, and the water is introduced into the collecting box 51 through the circular hole, and the gas after preliminary treatment continues to be transported backward and introduced into the dewatering cylinder 8 through the air guide frame 6, and the treated gas is intercepted horizontally and vertically by the multi-layer interception net 10 in the dewatering cylinder 8 to further capture the remaining water in the gas. The remaining tiny water droplets, in the process of secondary water removal, the first motor 7 can drive the water removal cylinder 8 to rotate, and the rotation of the water removal cylinder 8 can throw out the water captured on the interception net 10 through the strip holes, and the thrown water droplets are intercepted and collected by the arc-shaped guide plate 9 and diverted downward, so that the water droplets enter the collection box 51 from the bottom of the water removal tank 1, and the gas from the secondary water removal will also be discharged from the strip holes to the front part of the water removal tank 1, and finally discharged through the outlet pipe 3. In this way, the effect of removing water from the tail exhaust of hydrogen fuel cell vehicles can be greatly improved, ensuring driving safety while also reducing the impact on the environment.

[0035] like Figure 7 and Figure 8As shown, the water removal component includes a second motor 11, an extrusion wheel 12, a slider 13, a first spring 14 and a scraper 15. The second motor 11 is embedded and fixedly connected to the right front part of the condensation chamber 4, and the extrusion wheel 12 is fixedly connected to the output shaft of the second motor 11. The sliders 13 are slidably connected to the left and right sides of the condensation chamber 4. The first spring 14 is connected between the slider 13 and the condensation chamber 4.

A wedge-shaped protrusion is provided on the front right side of the scraper 15, and the extrusion wheel 12 rotates to squeeze and cooperate with the wedge-shaped protrusion.

[0036] When using the device, the second motor 11 operates to control the rotation of the extrusion wheel 12. When the extrusion wheel 12 rotates to contact the wedge-shaped protrusion on the scraper 15, the extrusion wheel 12 continues to rotate and squeezes the scraper 15 downward through the wedge-shaped protrusion. The downward movement of the scraper 15 drives the slider 13 to slide downward, and the first spring 14 is deformed. When the extrusion wheel 12 rotates to separate from the wedge-shaped protrusion on the scraper 15, under the action of the first spring 14 resetting, the slider 13 drives the scraper 15 to move upward and reset. When the extrusion wheel 12 rotates again to contact the wedge-shaped protrusion on the scraper 15, repeating the above action can make the scraper 15 move up and down continuously. The up and down movement of the scraper 15 can scrape off water droplets attached to the surface of the refrigeration pipe 5 to prevent water freezing from affecting the refrigeration effect of the refrigeration pipe 5.

[0037] Embodiment 2: Based on embodiment 1, Figure 1 , Fig. 9 , Fig.10 and Fig.11 As shown, a cooling component for lowering the temperature inside the dewatering tank 1 is also included, and the cooling component includes a cooling pipe 16, a suction pump 17, a drainage rack 18, a solenoid valve 19 and a liquid level sensor 20. The front right side of the collecting box 51 is connected to the cooling pipe 16, and the cooling pipe 16 is coiled on the surface of the dewatering tank 1. The front left side of the collecting box 51 is connected to the suction pump 17, and the suction pump 17 is connected to the tail end of the cooling pipe 16. The lower side of the collecting box 51 is connected to the drainage rack 18, and the solenoid valve 19 is fixedly connected to the drainage rack 18. The front inside the collecting box 51 is fixedly connected to the liquid level sensor 20, and the liquid level sensor 20 is electrically connected to the solenoid valve 19 and the suction pump 17.

[0038] When the device is used, all the separated water is gathered in the collection box 51 for collection, and the liquid level sensor 20 can monitor the water volume in the collection box 51. When the water volume in the collection box 51 reaches a first preset value, the liquid level sensor 20 can control the suction pump 17 to operate through the control module, and the suction pump 17 operates to draw the water in the collection box 51 into the cooling pipe 16, so that the water circulates in the cooling pipe 16 and the collection box 51, and cools the inside of the dewatering tank 1 through the cooling pipe 16 to improve the condensation effect of the tail exhaust gas inside the dewatering tank 1. When the water volume in the collection box 51 reaches a second preset value, the liquid level sensor 20 can control the solenoid valve 19 to open through the control module, and the water in the collection box 51 can be discharged through the drainage rack 18.

[0039] like Fig.12 , Fig.13 and Fig.14 As shown, it also includes a dispersion component for controlling the dispersion of tail exhaust gas in the condensation chamber 4, the dispersion component includes a diverter plate 21, a connecting plate 22, a bar rail 23, a sliding rod 24, a second spring 25 and a matching block 26, three equidistantly distributed diverter plates 21 are rotatably connected to the rear part of the dewatering tank 1, two symmetrical connecting plates 22 are rotatably connected between the three diverter plates 21, the diverter plate 21 on the right side is fixedly connected to the bar rail 23 at the rotating connection with the dewatering tank 1, the sliding rod 24 is slidably connected to the rear lower part of the condensation chamber 4, the rear end of the sliding rod 24 is movably connected to the bar rail 23, the second spring 25 is connected between the sliding rod 24 and the condensation chamber 4, the front end of the sliding rod 24 is fixedly connected to the matching block 26, the upper side surface of the matching block 26 is inclined, and the scraper 15 slides downward to be squeezed and matched with the matching block 26.

[0040] When the device is used, when the scraper 15 moves downward until it contacts the matching block 26, the scraper 15 continues to move downward to push the matching block 26 to move backward. The matching block 26 moves backward and drives the sliding rod 24 to slide backward. The second spring 25 is deformed, and the sliding rod 24 slides backward to push the bar rail 23 to swing backward. The bar rail 23 swings backward and drives the right diverter plate 21 to rotate. Under the action of the connecting plate 22, the other two diverter plates 21 will also rotate synchronously. When the scraper 15 moves upward and no longer squeezes the matching block 26, the sliding rod 24 drives the matching block 26 to move backward under the action of the second spring 25 returning to its original position. 26 moves forward to reset, the sliding rod 24 slides forward to drive the bar rail 23 to swing forward, the bar rail 23 swings forward to drive the right diverter plate 21 to reverse, and the connecting plate 22 also drives the other two diverter plates 21 to reverse, and when the scraper 15 moves downward again to contact with the matching block 26, repeating the above actions can make the diverter plate 21 rotate left and right continuously, and when the intake pipe 2 introduces the tail exhaust into the dewatering tank 1, the tail exhaust is dispersed by the diverter plate 21 rotating left and right, so that the tail exhaust is dispersed to various places of the condensation chamber 4, so as to improve the condensation and water removal effect and avoid the tail exhaust from directly passing through the middle of the condensation chamber 4 and being discharged.
