AI Technical Summary
In existing photocatalytic wastewater treatment devices, the liquid-liquid and gas-liquid mixing effects are poor, the internal flow field of the photocatalytic tubular reactor is uneven, and the commonly used water distribution baffle has problems such as high pressure, high processing requirements, and high energy consumption.
The system employs a multi-segment cross-flow mixing pipeline, an ultrasonic tank, and a photocatalytic reactor. The cross-flow mixing pipeline is distributed in a tree-like pattern, with side channels at the confluence of branch pipes. Baffles are designed with different orifice diameters according to pressure zones. Combined with a microchannel reactor and a Tesla valve, it achieves multi-stage diversion and convergence. The water distribution baffles and outlet baffles are designed with different zones according to pressure zones.
It achieves uniform mixing of liquid-liquid and gas-liquid, reduces flow field resistance, improves mixing efficiency, homogenizes flow field distribution, reduces energy consumption, and improves the mixing tolerance of the device.
