Static mixer device for improving homogeneity of a characteristic of a mixture stream created from fluid streams separately entering the device

摘要

A static mixer device for mixing separate fluid streams entering the device in order to achieve a more uniform, or homogeneous, characteristic, such as temperature for example, in the resulting fluid mixture stream exiting the device. An exemplary embodiment of device comprises a series of parallel rectangular walls arranged in side-by-side, spaced apart relationship to form a series of rectangular spaces. The perimeters of these spaces are selectively closed to define respective first and second inlets and an outlet. The inlets sub-divide the respective entering fluid streams into sheet-like streams that are interleaved as they exit the device at the outlet. This interleaving of one stream with the other promotes increased homogeneity of the mixture stream in a shorter distance downstream of the confluence of the entrance streams. Turning vanes are provided for turning one of the sub-divided streams as it passes through the exemplary embodiment of mixer which is used as an air mixer in a coal-fired power plant.
