The direct exhaust end with hydrogen fuel cell of connecting pipe 1 one end is connected, and 2 left ends of hydrogen mixer are connected to the connecting pipe 1 other end, and hydrogen mixer 2's primary function reduces the hydrogen average concentration in the waste gas for mixed hydrogen and vapor, prevents that local high concentration region from producing. The right end of the hydrogen mixer 2 is connected with a tail pipe 3, the tail pipe 3 is used for discharging waste gas, and the tail end of the tail pipe 3 is provided with a 45-degree folded angle, so that the waste gas is prevented from being directly discharged to pedestrians.
As shown in fig. 2-3, the hydrogen mixer 2 is mainly composed of eight parts, namely an outer cylinder 2-1, a front end cover 2-2, a front cyclone blade 2-3, a front fixing ring 2-4, a shunt pipe 2-5, a rear cyclone blade 2-6, a rear fixing ring 2-7, a rear end cover 2-8 and the like.

The front swirl blades 2-3 are fixed in the middle of the front fixing ring 2-4, and the rear swirl blades 2-6 are fixed in the middle of the rear fixing ring 2-7, so that the effect of rotationally mixing hydrogen and water vapor flows is mainly achieved. The left end of the outer cylinder body 2-1 and the left end of the front fixing ring 2-4 are connected with the front end cover 2-2, and the right end of the outer cylinder body 2-1 and the right end of the rear fixing ring 2-7 are connected with the rear end cover 2-8.

As shown in figure 5, the shunt pipe 2-5 is hollow cylinder, and the upper end of the shunt pipe is densely distributed with shunt holes 2-5-1 which are mainly used for shunting hydrogen and water vapor.
As shown in figure 4, the front fixed ring 2-4 is ring-shaped, the front fixed ring 2-4 is provided with an airflow groove 2-4-1, the inner ring of the front fixed ring 2-4 is provided with a front cyclone blade 2-3, as shown in figure 6, the front cyclone blade 2-3 is composed of blades which are mutually overlapped, thus a larger back pressure can be formed while a turbulent flow effect is achieved.
As shown in figure 7, the rear swirl vanes 2-6 are composed of vanes with inclined angles, and the turbulence effect is good.
The working process of the invention is as follows:
the exhaust gas of a hydrogen fuel cell vehicle is mainly water vapor, but there is a small amount of hydrogen gas discharged under-use. Especially at the time of cold start and shut down of the automobile, the amount of hydrogen gas that is not fully utilized may greatly increase. The low density characteristic of hydrogen gas results in its extreme tendency to accumulate above the space in which it is located, which results in a localized high concentration of hydrogen gas above the exhaust.
When an automobile is started and shut down in a cold state, most of mixed gas of hydrogen and steam is kept in an idle working condition, the exhaust flow is small, the exhaust flow rate is low, when the discharged mixed gas of the hydrogen and the steam flows through the exhaust mixing device, the mixed gas firstly enters the hydrogen mixer 2 through the connecting pipe 1, part of the hydrogen gathered above the connecting pipe 1 is gathered above the hydrogen mixer 2, and enters a cavity between the outer barrel body 2-1 and the shunt pipe 2-5 through the airflow groove 2-4-1 on the front fixing ring 2-4 and is gathered above the cavity. The other part of the waste gas forms a rotating airflow through the front rotating flow blades 2-3, enters the shunt tubes 2-5 and is continuously shunted in the shunt tubes 2-5. The hydrogen with low density enters a cavity between the shunt pipe 2-5 and the outer barrel 2-1 through the shunt hole 2-5-1 above the shunt pipe 2-5 to be gathered, the shunted water vapor further forms strong rotational flow through the rear rotational flow blade 2-6 to enter the tail pipe 3, and the strong rotational flow further mixes the hydrogen and the water vapor which are shunted out and discharges the mixture into the atmosphere. The tail pipe 3 is provided with a short length, mainly to prevent further accumulation of the hydrogen to be branched off in the tail pipe 3.
When the hydrogen fuel cell automobile enters a high-speed running working condition, the hydrogen can be basically and completely utilized, and the concentration of the hydrogen in the exhaust gas is greatly reduced. At the moment, the exhaust flow and the exhaust flow rate are greatly increased, the rotating action of the hydrogen mixer 2 on the mixed waste gas of the exhausted hydrogen and the steam is greatly improved, and the high-speed rotating airflow can take away the hydrogen which flows out from the cavity between the shunt pipe 2-5 and the outer barrel 2-1 under the idling working condition during cold start, so that the concentration of the hydrogen cannot exceed the standard under the high-flow working condition.
To sum up, under low flow conditions such as cold start, idling, etc., the concentration of hydrogen in the exhaust gas is extremely high, and the swirling effect in the hydrogen mixer 2 is weak. The hydrogen can be branched by the branch pipe 2-5 and retained in the hydrogen mixer 2, thereby reducing the hydrogen concentration of the exhaust gas. Under the working conditions of high power and high flow, the hydrogen is basically and completely utilized, and the concentration of the discharged hydrogen is extremely low. At this moment, the swirling flow effect is stronger in the hydrogen mixer, and the hydrogen and the steam which flow out in the low working condition can be mixed more uniformly and discharged.
