[0002] Engine exhaust is the waste gas generated when the engine is in use. It contains hundreds of different compounds, among which pollutants include solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead and sulfur oxides, etc. In today's life, power outages often occur due to various reasons. In emergency situations, diesel engines are usually used to generate electricity. When the diesel engine is generating electricity, the exhaust gas emitted by it needs to be purified, so a purification device is needed. The purification device will first treat the exhaust gas evenly before treating it. In summary, the existing purification device usually uses a plastic bag directly on the surface of the water pump to protect it. The plastic bag is easy to break when used, and the protection effect is poor, resulting in the inability to protect the water pump. At the same time, there is no device to prevent impurities from falling into the water tank. Impurities and dust enter the water tank, which will cause water pollution. When spraying the exhaust gas, the purification effect will be poor, reducing practicality and convenience, and inconvenient for users.
