Gas-liquid countercurrent heat exchange device

TLDR: In this article, the authors proposed a gas-liquid countercurrent heat exchange device with a plurality of liquid channels arranged in the length direction, where the gaps between the adjacent layers are arranged to form the gas flow channels.

Abstract: The utility model relates to the field of heat exchangers. The utility model provides a gas-liquid countercurrent heat exchange device. The device comprises a strip-shaped pore plate, the strip-shapedpore plate is provided with a plurality of liquid channels arranged in the length direction. The liquid channel vertically penetrates through the strip-shaped pore plate, the strip-shaped pore plateis rolled into a multi-layer tube plate structure, adjacent layers are arranged at intervals to form an airflow channel, an air inlet is formed in the lower end of the airflow channel, an air outlet is formed in the upper end of the airflow channel, a liquid inlet is formed in the upper end of the liquid channel, and a liquid outlet is formed in the lower end of the liquid channel. According to the gas-liquid countercurrent heat exchanger, the strip-shaped pore plates with the liquid channels are rolled into a multi-layer tube plate structure, and the gaps between the adjacent layers are arranged to form the gas flow channels, so that liquid flows through the liquid channels from top to bottom, air flows through the gas flow channels from bottom to top, countercurrent heat exchange betweengas and liquid is realized, and the heat exchange efficiency is improved.
