[0023] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, but should not be construed as limiting the present utility model.
[0024] The vehicle tail gas treatment system and the vehicle having the same according to the embodiments of the present utility model will be described below with reference to the drawings.
[0025] Before introducing the vehicle tail gas treatment system and the vehicle having the same according to the embodiments of the present utility model, the vehicle tail gas treatment system adopted in the related art will be briefly introduced.
[0026] Specifically, as Figure 1 shownFigure 1 It is a schematic structural diagram of a hydrogen fuel cell vehicle exhaust water-vapor separation and emission system in the related art, where:
[0027] 1 is the fuel cell tail exhaust outlet, 2 is the drawn hydrogen and water-vapor mixed pipeline, 3 is the air and water-vapor mixed pipeline, 5 is the first gas-liquid separator, 6 is the second gas-liquid separator, 51 and 61 are the exhaust pipes after separation respectively, 52 and 62 are the corresponding drain pipes respectively, 41 is the drain tank, 42 is the exhaust tank, which collect the water and gas in the above pipelines respectively. A liquid level sensor 7 is installed inside the drain tank 41. After detecting that the water level in the tank is full, a signal is sent to the controller FCU, and the FCU drives the solenoid valve 64 to open, and the water in the tank is discharged from the discharge port 10. The solenoid valve 64 can also be controlled to open and close through the cab button. A branch pipe 53 is branched from the pipeline 51 to transport the hydrogen in 51 to the hydrogen supply system 12 to realize the recycling of hydrogen.
[0028] However, in the actual treatment of the above hydrogen fuel cell vehicle exhaust water-vapor separation and emission system, the hydrogen concentration in the tail exhaust gas is relatively low, the amount of hydrogen that can be utilized is limited, and the unpurified hydrogen is difficult to utilize; at the same time, when the vehicle is working in cold regions, after the liquid water is stored in the tank for a period of time, the inside of the tank is prone to be blocked by ice, resulting in the inability to discharge the liquid water, which greatly affects the safety and stability of the vehicle tail exhaust treatment system.
[0029] Exactly to solve the problems of low actual effect of hydrogen recovery and easy icing during the storage of tail exhaust water vapor, the present utility model provides a vehicle tail exhaust treatment system. In this system, the hydrogen component in the tail exhaust gas is removed by a hydrogen removal device, and then the water vapor in the tail exhaust gas is separated by a water-vapor separation device. The separated liquid water is stored in a water storage device, and the liquid water is discharged regularly or automatically. Thus, by adding a hydrogen removal device and a water-vapor separation device, the gas-liquid separation treatment of the tail exhaust is realized, and the safety and stability of the tail exhaust treatment system are improved.
[0030] Specifically, Figure 2 It is a schematic diagram of a vehicle tail exhaust treatment system provided by an embodiment of the present utility model.
[0031] As Figure 2 shown, the vehicle tail exhaust treatment system 20 includes: a hydrogen removal device 100, a water-vapor separation device 200, a water storage device 300, and a heat conduction device 500.
[0032] Among them, the input end of the hydrogen removal device is connected to the tail gas outlet of the fuel cell system, which is used to remove hydrogen in the tail gas at the tail gas outlet to obtain the gas to be discharged; the input end of the water vapor separation device is connected to the output end of the hydrogen removal device, and the first output end of the water vapor separation device is connected to the atmosphere, which is used to separate water vapor from the gas to be discharged and discharge the separated gas to the atmosphere through the first output end of the water vapor separation device; the input end of the water storage device is connected to the second output end of the water vapor separation device, which is used to store the liquid water after the water vapor separation device separates water vapor from the gas to be discharged; the heat conduction device is arranged between the hydrogen removal device and the water storage device, which is used to conduct the heat generated when the hydrogen removal device removes hydrogen in the tail gas at the tail gas outlet to the water storage device to heat the liquid water in the water storage device.
[0033] Specifically, when the fuel cell stack generates electricity, due to the oxidation-reduction reaction, tail gas mixture is generated inside the stack. There are hydrogen, air, liquid water, water vapor, etc. in the tail gas. These gases cannot participate in the chemical reaction again due to their low concentration. At the same time, if the liquid water and water vapor cannot be discharged in time, it will cause the gas flow channel to be blocked and local "flooding" phenomenon to occur. Therefore, while the fuel cell is working, the tail gas must be discharged from the inside of the fuel cell. These tail gases are discharged from the tail gas outlet of the fuel cell system and enter the inside of the hydrogen removal device 100. The hydrogen removal device 100 reacts with the hydrogen in the tail gas, thereby absorbing the hydrogen with a lower concentration therein. After the hydrogen in the tail gas is absorbed, it becomes the gas to be discharged. The gas to be discharged enters the input end of the water vapor separation device 200 through the output end of the hydrogen removal device 100. The water vapor separation device 200 separates the liquid water and water vapor in the gas to be discharged. After separation, only air and a very small amount of hydrogen-water vapor mixture remain in the gas to be discharged, and the separated gas can be discharged to the atmosphere through the first output end of the water vapor separation device 200. The liquid water separated by the water vapor separation device 200 is output to the water storage device 300 through the second output end, and the liquid water is stored in the water storage device 300. After the tail gas enters the hydrogen removal device 100, it reacts with the catalyst in the hydrogen removal device 100, and heat is generated in this process. In the embodiment of the present utility model, the heat conduction device 500 is arranged to connect the hydrogen removal device 100 and the water storage device 300, and the heat generated by the hydrogen removal device 100 during the hydrogen removal process is transferred to the water storage device 300, so that the temperature in the water storage device 300 is kept above zero degrees, preventing the liquid water in the water storage device 300 from freezing and avoiding the blockage of the drainage pipeline.
[0034] Optionally, in some embodiments, for the above vehicle tail gas treatment system 20, the heat conduction device 500 is a heat conduction plate.
[0035] Specifically, the heat conduction device 500 in the embodiment of the present utility model is a heat conduction plate. One side of the heat conduction plate is closely attached to the hydrogen removal device 100 of the tail gas treatment device, and the other side is closely attached to the water storage device 300. Through the property of the heat conduction plate, the heat generated during the chemical reaction of the hydrogen removal device 100 is quickly and evenly transferred to the water storage device 300, so that the internal temperature of the water storage device 300 is maintained above zero degrees, preventing the liquid water in the water storage device 300 from freezing and causing the drainage pipeline to be blocked.
[0036] Optionally, in some embodiments, the above-mentioned vehicle tail gas treatment system 20 further includes: a first switch assembly, a first detection assembly, and a control assembly. Among them, the first switch assembly is arranged at the first output end of the water storage device 300; the first detection assembly is connected to the water storage device 300, and the first detection assembly is used to detect the water storage volume of the water storage device 300; the control assembly is respectively connected to the first detection assembly and the first switch assembly. When the water storage volume is greater than the preset water volume, the control assembly controls the first switch assembly to open, so as to discharge the liquid water in the water storage device 300 through the first switch assembly.
[0037] Specifically, the first switch assembly is arranged at the first output end of the water storage device 300, and the first detection assembly is connected to the water storage device 300. The user can preset the drainage conditions through the first detection assembly. After the preset conditions are met, the control assembly controls the switch of the first switch assembly to achieve the effect of automatically discharging the liquid water in the water storage device 300.
[0038] Exemplarily, the first detection assembly can be a weight sensor. When the user presets that the weight sensor senses that the weight of the water storage device 300 reaches a certain weight, the water storage device 300 automatically discharges the liquid water therein. After the gravity sensor meets the drainage conditions, the control assembly controls the first switch assembly to open the first output end of the water storage device 300 and control the liquid water to be discharged.
[0039] Among them, in some embodiments, the first switch assembly is an electromagnetic valve.
[0040] Specifically, after the first detection assembly detects that the drainage conditions are met, the control assembly controls the electromagnetic valve to be energized. The electromagnetic valve body inside the electromagnetic valve is attracted, and the control valve is opened, and the liquid water is discharged through the electromagnetic valve and the first output end.
[0041] Optionally, in some embodiments, the above-mentioned vehicle tail gas treatment system 20 further includes: a second switch assembly and a trigger button arranged on the second switch assembly. Among them, the second switch assembly is arranged at the second output end of the water storage device 300 and is used to be in an open state when the trigger button is triggered, so as to discharge the liquid water in the water storage device 300.
[0042] Specifically, in the embodiments of the present utility model, a second switch assembly may further be provided. There is a trigger button in the second switch assembly. When the first switch assembly fails or the drainage condition is not yet met, but the user independently determines that the water storage device 300 needs to be drained, the on / off state of the trigger button can be manually switched. When the trigger button is in the on state, the liquid water in the water storage device 300 is discharged through the second output end.
[0043] Optionally, in some embodiments, in the above vehicle tail gas treatment system 20, the water storage device is a water storage tank.
[0044] Specifically, by way of example, the water storage device in the embodiments of the present utility model may be a water storage tank. The water storage tank is connected to the water vapor separation device, and is used to store the liquid water separated from the gas to be discharged by the water vapor separation device, and the liquid water is discharged by using the switch assembly provided at the output end of the water storage tank.
[0045] Optionally, in some embodiments, the water vapor separation device 200 includes: a baffle type water vapor separation unit, the input end of the baffle type water vapor separation unit is connected to the output end of the deoxidation device, and is used for performing baffle type water vapor separation on the gas to be discharged by the solenoid valve; and / or, a centrifugal water vapor separation unit, the input end of the centrifugal water vapor separation unit is connected to the output end of the deoxidation device, and is used for performing centrifugal water vapor separation on the gas to be discharged by the solenoid valve; and / or, a turbine type water vapor separation unit, the input end of the turbine type water vapor separation unit is connected to the output end of the deoxidation device, and is used for performing turbine type water vapor separation on the gas to be discharged by the solenoid valve.
[0046] Specifically, the input end of the baffle type water vapor separation unit is connected to the output end of the deoxidation device 100. After the gas to be discharged enters the baffle type water vapor separation unit, the flow direction of the water vapor is changed multiple times through a plurality of built-in baffles, so that the water vapor in the gas to be discharged condenses into liquid water after touching the baffle, and converges at the bottom under the action of gravity; the input end of the centrifugal water vapor separation unit is connected to the output end of the deoxidation device 100. After the gas to be discharged enters the centrifugal water vapor separation unit, a series of fins are arranged inside to generate a high-speed air flow, so that the gas to be discharged rotates at a high speed to separate the internal water vapor; the input end of the turbine type water vapor separation unit is connected to the output end of the deoxidation device 100. After the gas to be discharged enters the turbine type water vapor separation unit, the water vapor in the gas to be discharged condenses into liquid water through internal pressurization.
[0047] It should be noted that the water-vapor separation device 200 in the embodiments of the present utility model can be composed of any one type of water-vapor separation unit, or can be composed of any combination of the above-mentioned several water-vapor separation units. For example: a baffle type water-vapor separation unit, or a centrifugal type water-vapor separation unit, or a turbine type water-vapor separation unit, or a combination of a baffle type water-vapor separation unit and a centrifugal type water-vapor separation unit, or a combination of a baffle type water-vapor separation unit and a turbine type water-vapor separation unit, or a combination of a centrifugal type water-vapor separation unit and a wheel type water-vapor separation unit, or a combination of a baffle type water-vapor separation unit, a centrifugal type water-vapor separation unit and a turbine type water-vapor separation unit. The present utility model does not make specific limitations herein.
[0048] Optionally, in some embodiments, the hydrogen removal device 100 includes: a platinum mesh disposed within the hydrogen removal device 100.
[0049] Specifically, when the tail exhaust gas enters the hydrogen removal device 100, the rate of the redox reaction increases under the catalysis of oxygen and the platinum mesh (catalyst) in the tail exhaust gas, so that the low-concentration hydrogen in the tail exhaust gas is quickly consumed. At the same time, heat is generated during the redox reaction, causing the temperature of the hydrogen removal device 100 to rise and conducting the heat to the heat conduction device. The chemical equation of this exothermic redox reaction is as follows:
[0050] \[2H_2 + O_2 \rightarrow 2H_2O\]
[0051] Optionally, in some embodiments, the above-mentioned vehicle tail exhaust treatment system 20 further includes: a second detection component and a reminder component. The second detection component is connected to the platinum mesh and is used to detect the remaining life of the platinum mesh; the reminder component is connected to the second detection component and is used to give a replacement reminder when the remaining life of the platinum mesh is less than the preset life.
[0052] Wherein, the preset life refers to the threshold value of the remaining life of the preset platinum mesh, which can be a threshold value set by those skilled in the art according to the actual requirements of the heating device, or can be data obtained through a limited number of computer simulations. Specific limitations are not made herein.
[0053] Specifically, the second detection component is connected to the platinum mesh and can detect the remaining life of the platinum mesh. When it detects that the remaining life of the platinum mesh is less than the preset life, a replacement reminder is given through the reminder component.
[0054] In order to further illustrate the vehicle tail exhaust treatment system of the present utility model, the present utility model will be described below in conjunction with specific embodiments.
[0055] As Figure 3 shown, Figure 3 is a schematic structural diagram of a vehicle tail exhaust treatment system provided according to a specific embodiment of the present utility model.
[0056] Among them, the vehicle tail gas treatment system 20 includes: a hydrogen removal device 100, a water vapor separation device 200, a water storage tank 300, a solenoid valve 400, and a heat conduction device 500.
[0057] Among them, the input end of the hydrogen removal device 100 is connected to the output end of the fuel cell. The output end of the hydrogen removal device 100 is connected to the input end of the water vapor separation device 200. At the same time, the hydrogen removal device 100 is connected to the input end of the heat conduction device 500. One output end of the water vapor separation device 200 is connected to the input end of the water storage tank 300. The other output end of the water vapor separation device 200 is connected to the atmosphere. The output end of the water storage tank 300 is connected to the solenoid valve 400. At the same time, the water storage tank 300 is connected to the output end of the heat conduction device 500. The output end of the solenoid valve 400 is connected to the atmosphere.
[0058] Specifically, the tail gas first passes through the hydrogen removal device 100 to remove hydrogen in the tail gas components. Then it passes through the water vapor separation device 200 to separate the water vapor and liquid water components, which are stored in the water storage tank 300. Controlled by the solenoid valve 400, the liquid water is discharged according to requirements. Finally, the remaining air in the tail gas is discharged into the atmosphere.
[0059] Among them, the hydrogen removal device 100 is based on the oxidation-reduction reaction of hydrogen and oxygen. Hydrogen reacts with oxygen in the air through the platinum mesh (catalyst) in the device to undergo an oxidation-reduction reaction, consuming hydrogen. The heat generated by the hydrogen removal device 100 is conducted to the water storage tank 300 through the heat conduction device 500, which can prevent the water in the water storage tank 300 from freezing in winter. The water vapor separation device 200 can select a water vapor separation scheme such as a baffle type, a centrifugal type, or a turbine type according to the specific usage situation to achieve water vapor separation. The separated water is stored in the water storage tank 300. The controller can control the opening and closing of the solenoid valve 400 to achieve automatic full-water discharge and manual button discharge.
