一种使用管内混合器的多管气态燃料掺混器
摘要：
本发明提供了一种使用管内混合器的多管气态燃料掺混器，包括壳体，该壳体内沿径向同轴设置有中心燃料通道、外围燃料通道和环形空气通道；所述外围燃料通道包括外围燃料输送管，和连接在该外围燃料输送管外壁上的若干周向布置的外围燃料喷嘴；所述环形空气通道包括外围空气通道和中心空气通道，所述外围空气通道和中心空气通道内分别设置有外围旋流装置和中心旋流装置；所述外围旋流装置包括若干周向均布的管道，且在该管道内轴向布置有若干管内混合器。本发明中，外围通道的多管预混模式和管内混合器的应用，使油气掺混均匀，降低污染排放。
摘要（英）：

The invention provides a multi-pipe gas-state fuel mixer using in-pipe mixers. The multi-pipe gas-state fuel mixer comprises a shell; a center fuel channel, a peripheral fuel channel and an annular air channel are coaxially formed in the shell in the radial direction; the peripheral fuel channel comprises a peripheral fuel conveying pipe, and multiple peripheral fuel nozzles peripherally arranged and connected to the outer wall of the peripheral fuel conveying pipe; the annular air channel comprises a peripheral air channel and a center air channel; a peripheral cyclone device and a center cyclone device are respectively arranged in the peripheral air channel and the center air channel; the peripheral cyclone device comprises multiple pipes uniformly distributed in the peripheral direction; and multiple in-pipe mixers are axially distributed in the pipes. Through a multi-pipe premixing mode of the peripheral channel and application of the in-pipe mixers, the oil-gas mixing is uniform, and the pollution emission is reduced.
