AI Technical Summary

Technical Problem

Existing odor gas absorption devices in chemical plants suffer from low mass transfer efficiency, high cost, large equipment size, and susceptibility to loads such as eccentricity, wind, and earthquakes. Small and medium-sized enterprises also have serious problems with illegal discharge and leakage.

Method used

The absorption and reuse tower adopts a multi-layer tray design, combining liquid jet and strong swirling airflow field to absorb odor gases through a multi-stage series connection. The absorption liquid is reused multiple times by using an external liquid circulation device. The spiral airflow field is formed by side wall micropore liquid inlet and tangential air inlet to enhance gas-liquid mass transfer efficiency.

Benefits of technology

It improves gas-liquid mass transfer efficiency, reduces initial investment and operating costs, simplifies system structure, is easy to maintain, and is suitable for the absorption of odor gases with large volumes and low levels of harmful components, achieving efficient absorption of odor components and recycling of the absorbent liquid.
