The application discloses fuel cell vehicle exhaust apparatus, including encapsulation casing 1, first temperature sensor 2, first humidity transducer 3, second temperature sensor 4, second humidity transducer 5, first fan group 6 and controller 7.

The conditions for generating white gas are explained here, and the reason why the white gas is generated when the tail gas enters the environment is that the first tail gas temperature is higher than the ambient temperature and the first tail gas humidity is higher than the ambient humidity. When no white gas is generated, the environment temperature is higher than the first tail gas temperature and/or the environment humidity is higher than the first tail gas humidity, namely the first temperature difference is larger than 0 and/or the first humidity difference is larger than 0;
when white gas is generated, the ambient temperature is required to be lower than the first tail gas temperature and the ambient humidity is required to be lower than the first tail gas humidity, namely, the first temperature difference is less than or equal to 0 and the first humidity difference is less than or equal to 0.
Therefore, the first condition for generating the white gas is that the first temperature difference is less than or equal to 0 and the first humidity difference is less than or equal to 0;
the second condition for not generating white gas is that the first temperature difference is > 0 and/or the first humidity difference is > 0.
The fuel cell vehicle exhaust apparatus disclosed in the present application further includes a third temperature sensor 8 and a third humidity sensor 9.
The third temperature sensor 8 and the third humidity sensor 9 are used for collecting the second tail gas temperature and the second tail gas humidity of the gas discharged from the gas outlet 112, comparing the second tail gas temperature and the second tail gas humidity with the ambient temperature and the ambient humidity respectively, and judging whether the tail gas discharged from the gas outlet 112 meets the condition of generating white gas.
If a second temperature difference between the ambient temperature and the second tail gas temperature and a second humidity difference between the ambient humidity and the second tail gas humidity meet the condition of generating white air, the controller 7 increases the air volume of the first fan set 6;
and if the second temperature difference between the ambient temperature and the second tail gas temperature and the second humidity difference between the ambient humidity and the second tail gas humidity meet the condition that no white air is generated, the controller 7 reduces the air volume of the first fan set 6.
The conditions for generating white gas are explained here, and the reason why the tail gas enters the environment to generate white gas is that the temperature of the second tail gas is higher than the ambient temperature, and the humidity of the second tail gas is higher than the ambient humidity. When no white gas is generated, the environment temperature is higher than the second tail gas temperature and/or the environment humidity is higher than the second tail gas humidity, namely the second temperature difference is larger than 0 and/or the second humidity difference is larger than 0;
when the white gas is generated, the environment temperature is required to be lower than the second tail gas temperature and the environment humidity is required to be lower than the second tail gas humidity, namely, the second temperature difference is less than or equal to 0 and the second humidity difference is less than or equal to 0.
Therefore, the third condition for generating the white gas is that the first temperature difference is less than or equal to 0 and the first humidity difference is less than or equal to 0, and simultaneously the second temperature difference is less than or equal to 0 and the second humidity difference is less than or equal to 0;
the fourth condition for not generating white gas is that the first temperature difference is > 0 and/or the first humidity difference is > 0, the second temperature difference is > 0 and/or the second humidity difference is > 0.
In order to further optimize the technical scheme, the exhaust device of the fuel cell vehicle further comprises a second fan set 10.
The second fan set 10 is arranged in the packaging shell 1 and located at the downstream of the silencer 14 and used for cooling tail gas located in the packaging shell 1, and the second fan set 10 is in communication connection with the controller 7.
Specifically, when the air volume of the first fan set 6 is adjusted to the maximum, a second temperature difference between the second exhaust gas temperature and the ambient temperature and a second humidity difference between the second exhaust gas humidity and the ambient humidity satisfy a condition of generating white air, and at this time, the controller 7 adjusts the air volume of the second fan set 10 to compensate the air volume of the first fan set 6.
Specifically, after the air volume of the first fan set 6 is adjusted, if a second temperature difference between the second exhaust gas temperature and the ambient temperature and a second humidity difference between the second exhaust gas humidity and the ambient humidity satisfy a condition of not generating white air, the controller 7 adjusts the air volume of the second fan set 10 to be reduced or even zero.
When the air volume of the second fan unit 10 is zero, the second fan unit 10 is in a shutdown state, and when the air volume of the second fan unit 10 is not zero, the second fan unit 10 is in a startup state.
In order to further reduce the water vapor discharged through the exhaust port 112, the water baffle 11 is arranged in the packaging shell 1, the water baffle 11 can stop the movement of the tail gas entering the packaging shell 1, so that the water vapor in the tail gas collides with the water baffle 11 to form condensed water, and the formed condensed water is discharged from the water outlet 113.
In some embodiments of the application, a hole through which the tail gas can pass is formed in the water baffle 11, the water vapor can be intercepted at a position on the water baffle 11 where the hole is not formed, and the hole in the water baffle 11 through which the tail gas can pass does not affect the emission of the tail gas. The number of the holes is plural, and the opening positions, the opening shapes and the opening sizes of the holes are selected by those skilled in the art according to actual needs, and are not particularly limited herein.
In some embodiments of the application, a strip-shaped through groove for tail gas to pass through is formed in the water baffle 11, water vapor can be intercepted at a position where the strip-shaped through groove is not formed in the water baffle 11, the strip-shaped through groove in the water baffle 11 can pass through tail gas, and emission of the tail gas is not affected. The number of the strip-shaped through grooves is multiple, and the positions, shapes and sizes of the strip-shaped through grooves are selected by the person skilled in the art according to actual needs, and are not particularly limited herein.
As shown in fig. 2, the water baffle 11 is an L-shaped water baffle 11, and the L-shaped water baffle 11 includes a first plate perpendicular to the axis of the package housing and a second plate parallel to the axis of the package housing, the first plate is perpendicular to the second plate, wherein the second plate is connected to the exhaust end of the package housing.
In order to improve the condensation effect of the water baffle 11 on water vapor, the water baffle 11 is a metal plate in the application.
Preferably, the splash plate 11 is disposed above the drain opening 113 and downstream of the second fan unit 10.
The water guard plate 11 is not limited to a metal plate, but may be a plastic plate, and is not particularly limited herein.
The present application utilizes condenser 12 and breakwater 11 to carry out the mass flow guide to the vapor of condensation for the comdenstion water that forms can be followed outlet 113 and discharged smoothly.
The fuel cell exhaust vehicle disclosed herein further includes a condenser 12, the condenser 12 being located upstream of the water guard 11 for condensing water vapor in the exhaust gas.
The water vapor in the tail gas is condensed by the condenser, so that the content of the water vapor in the tail gas can be greatly reduced, and the generated white gas is reduced.
As shown in fig. 2, the drain port 113 is provided with a fourth temperature sensor 13 disposed on the package case 1, and the fourth temperature sensor 13 is used for acquiring the drain temperature of the drain port 113.
The fourth temperature sensor 13 is in communication connection with the controller 7, and the controller 7 adjusts the air volume of the first fan set 6 and/or the second fan set 10 according to the drainage temperature.
Specifically, when the drainage temperature of the drainage outlet 113 collected by the fourth temperature sensor 13 is lower than the freezing temperature, the controller 7 reduces the air volume of the first fan set 6 and/or the second fan set 10 to increase the drainage temperature of the drainage outlet 113;
when the drain temperature of the drain port 113 detected by the fourth temperature sensor 13 is lower than the freezing temperature, the controller 7 does not operate.
When the drainage temperature collected by the fourth temperature sensor 13 is lower than the freezing temperature, the air volume of the first fan set 6 and the air volume of the second fan set 10 need to be reduced through the controller 7, and then whether white air is generated or not is considered. Once the drain 113 is blocked by freezing, the package case 1 cannot be used normally.
The step of reducing the generation of white air can be performed only when the temperature of the discharged water collected by the fourth temperature sensor 13 is higher than the freezing temperature.
In the process of reducing the white air, the first fan unit 6 is used as a fan for mainly cooling the tail gas, and the second fan unit 10 is used as an auxiliary fan unit.

In the area with lower ambient temperature, the effect of cooling the water vapor in the exhaust gas by using the first fan set 6 and/or the second fan set 10 is more obvious, which is beneficial to the popularization of the fuel cell vehicle in the area with lower ambient temperature.
Meanwhile, the content of the water vapor discharged through the exhaust port 112 is reduced, and the amount of the water vapor in the exhaust gas combined with the pollutants in the air is reduced, so that the harm to the health of people is reduced to a certain extent.
