AI Technical Summary

Technical Problem

Traditional waste gas treatment equipment cannot achieve uniform mixing of various waste gases, resulting in incomplete combustion, difficulty in stable delivery of low-pressure waste gas, and excessive fuel required for high-temperature combustion, which increases energy consumption and generates more nitrogen oxides. Existing combustion nozzle structures cannot meet the purification needs of complex industrial scenarios.

Method used

It adopts a combined structure of nozzle housing, porous outer tube, porous inner tube, fan blade tube, vacuum generator and combustion gun. The design of negative pressure chamber and variable diameter chamber realizes uniform mixing of exhaust gas. The fan blade tube generates rotating airflow and combustion gun for low temperature combustion. Combined with the porous structure, the combustion air volume can be adjusted to adapt to different exhaust gas flow and combustion conditions.

Benefits of technology

It achieves uniform mixing of various waste gases, improves combustion efficiency, reduces energy consumption, reduces secondary pollution, adapts to complex waste gas treatment scenarios, and enhances the compatibility and operational stability of the device.
