Hydrocarbon mixer device

According to the hydrocarbon mixer device, the exhaust pipe and the mixer blades are arranged, the mixer blades comprise the multiple U-shaped blades which are fixedly arranged on the inner wall of the exhaust pipe at intervals in the circumferential direction, the U-shaped openings of the U-shaped blades are fixed to the inner wall of the exhaust pipe, and through the action of the multiple U-shaped blades, airflow is more dispersed and more uniform; and therefore, the hydrocarbon mixed gas is uniformly mixed, the concentration of the mixed gas is low, the problem of high-temperature ablation in DPF regeneration is powerfully solved, the structure is compact, and the performance is excellent. 一种碳氢混合器装置，通过设置排气管和混合器叶片，且混合器叶片包括多个U型叶片并沿圆周方向间隔固设在排气管的排气管内壁上，而U型叶片的U型口与排气管内壁固定，通过多个U型叶片作用，使气流更分散、均匀，进而使碳氢混合气混合均匀、混合气浓度低，有力的解决DPF再生高温烧蚀问题，且结构紧凑，性能优异。
