GJH型管式冗余结合器主要是用作纯净水电厂和城区城市污水治疗厂的物理化学投药和混泥土操作过程。它是一些使水目标进行变化，可以存在水力发电有种碰撞的的结合提升装置。

This equipment is generally composed of 2 or 3 single pipes, which are combined in positive and reverse directions with each other. It is located in the middle of the pipeline and is flange - connected to the pipeline, enabling the coagulant, coagulant aid, and disinfectant added to be instantaneously mixed in the pipeline.

1. No additional power is required, which saves energy.
2. When the water flows through the mixer, paired shunts, cross-mixing, and reverse swirling are generated, with obvious effects. The mixing rate reaches over 90%.
3. It is easy to install, does not require maintenance, has small head loss, and low cost.
