Further, the spiral directions of the adjacent double helical twisting plates 230 are opposite, and the arrangement mode enables the fluid to continuously change the flow direction after passing through the adjacent double helical twisting plates 230, so that the fluid at the center can be pushed to the periphery, and the fluid at the periphery is pushed to the center, thereby obtaining good radial mixing effect.

In this embodiment, the spiral direction of the single spiral twisted piece 220 is right-handed, the spiral direction of the spiral twisted piece in the adjacent double spiral twisted piece 230 is right-handed, and the spiral direction of the spiral twisted piece in the adjacent double spiral twisted piece 230 is left-handed, right-handed, and left-handed in sequence.

Further, the distance between the bottom end of the single helical twisting piece 220 and the top end of the adjacent double helical twisting piece 230 is larger than the distance between the bottom end of the double helical twisting piece 230 and the top end of the adjacent double helical twisting piece 230, and the distance is used for completely dispersing fluid and gas into the adjacent double helical twisting piece 230 through the single helical twisting piece 220 as far as possible and uniformly mixing the fluid and the gas through the double helical twisting pieces 230 in sequence.

Further, the housing 100 includes a cylinder 110, an inlet flange 120 fixed to one end of the cylinder 110, and an outlet flange 130 fixed to the other end of the cylinder 110, wherein a receiving cavity for receiving the mixing unit 200 is formed between the inlet flange 120 and the cylinder 110 and between the inlet flange 130 and the outlet flange 110, and the receiving cavity is a cylindrical cavity.

The fluid is continuously cut, sheared, rotated and remixed by the single helical twisting blade 220 and the double helical twisting blade 230 in the static mixer 10, and finally the required mixed fluid is formed, so that the continuous, efficient and rapid mixing process is realized. The static mixer 10 accomplishes a uniform mixing process by constantly changing the flow of the fluid (laminar and turbulent), wherein the precise design of the single 220 and double 230 helical blades results in a pressure loss of the static mixer 10 of no more than 0.5 Bar.
