Constant-speed balanced flue gas flow mixing device with high detection precision

The utility model discloses a constant-speed balanced flue gas flow mixing device with high detection precision. The constant-speed balanced flue gas flow mixing device comprises a lower ring block, a flow mixing bottle, a connecting rod, a middle ring block, an upper ring block, a circular plate, a silicone tube, a flue gas inlet, a mixing dual-purpose tube, a flow control valve, a spoiler, a flue gas outlet, a flute-shaped flue gas sampling tube, a circular plug, a drain hole and a slim hole. The flow control device is reasonable in structure, the flow of each path of inlet gas is judged by identifying the size and the rising speed of bubbles corresponding to each path of flute-shaped flue gas sampling pipe, and the corresponding flow control valve is adjusted, so that the sizes and the rising speeds of the bubbles corresponding to each path of flute-shaped flue gas sampling pipe 13 are consistent, and the purpose of constant-speed sampling and flow mixing is achieved; the labor intensity of workers and the
