AI Technical Summary
Technical Problem
Existing technologies have low cooling efficiency and high economic costs for high-temperature gases, and traditional cooling methods cannot meet the high-efficiency and stable cooling requirements of underground coal gasification production wellheads.
Method used
The structure employs a liquid-bearing structure, utilizing the pinning effect of the screen and capillary pressure design. The screen disperses high-temperature gas into bubbles that come into contact with the coolant, increasing the gas-liquid contact area and improving heat exchange efficiency.
Benefits of technology
It enables rapid and efficient cooling of high-temperature gases, extends equipment life, reduces maintenance costs, and improves the safety and reliability of underground coal gasification.
