AI Technical Summary
Technical Problem
In existing technologies, hydrogen is prone to stratification due to buoyancy when mixed in natural gas pipelines, posing a safety hazard.
Method used
A multi-stage mixing device is used to initially mix natural gas and hydrogen through a venturi tube, and then combined with a guide vane and mixing fan blades to achieve multi-stage mixing of the gas, avoiding stratification and local enrichment.
Benefits of technology
It achieves uniform blending of natural gas and hydrogen, improves the uniformity of the mixed gas, and eliminates safety hazards.

Abstract
The utility model relates to the technical field of natural gas mixing, and discloses natural gas hydrogen-doped multi-stage mixing equipment which comprises a first mixing box, the left side of the first mixing box is fixedly connected with a natural gas inlet pipe through a flange, and the bottom end of the first mixing box is fixedly connected with a hydrogen inlet pipe through a flange. The right side of the first mixing box is communicated with a second mixing box; the right side of the second mixing box is fixedly connected with a mixed gas outlet pipe through a flange; the first material mixing assembly comprises a disc and an air guide rotating pipe; and a mixing pipe. A first mixing assembly and an air guide rotating pipe are arranged to drive a disc to rotate to scatter and mix passing air flow, primary mixing of mixed gas is achieved, then the mixed gas enters a mixing pipe in a cavity of a second mixing box, the overall flow speed of the gas passing through an air duct is increased, and hydrogen is lighter in mass and prone to floating above, so that the mixing efficiency is improved. And the second mixing assembly is arranged to perform secondary mixing on the mixed gas, so that the uniformity of the mixed gas is further improved.
