AI Technical Summary
Existing diffusers for petrochemical applications cannot effectively achieve uniform diffusion when dealing with high-velocity, high-flow-rate gas-liquid materials. In particular, for liquid materials such as heavy oil, flow deviation is prone to occur, leading to excessive or insufficient local reactions within the reactor, thus reducing reaction efficiency and product quality.
The system employs a combined structure of a flow guide box, a diffusion device, and a dispersion box. By utilizing the cooperation between the hollow socket and the dispersion box, the flow direction of the gas and liquid materials is forcibly changed through baffles and reverse-inclined deflectors. The layout of the liquid inlet hopper and the gas inlet pipe allows the gas phase material to initially contact the liquid phase material. Combined with the rotation and stirring of the flow guide blades, multi-stage flow guidance and mixing are achieved.
It achieves circumferential diffusion and initial mixing uniformity of gas-liquid materials, avoids flow deviation, provides a uniform material base, lays the foundation for subsequent deep mixing, and improves reaction efficiency and product quality.
