The mixed heat exchanger is a common device for heat exchange, and the mixed heat exchanger transfers heat by direct contact of cold fluid and hot fluid, and the heat transfer mode avoids heat transfer partition walls and dirt resistance at two sides of the heat transfer partition walls, and has larger heat transfer rate as long as the contact condition between the fluids is good. Therefore, where fluids are allowed to mix with each other, a hybrid heat exchanger may be used, such as gas scrubbing and cooling, circulating water cooling, steam-water mixing heating, steam condensation, and the like.
The hot air recirculation, the bypass flue and the like are all regarded as relatively special hybrid heat exchangers. When the hot air recirculation and the bypass flue are arranged, the hot air or hot flue gas channel is directly connected with the side opening of the main path channel. This arrangement has a major disadvantage in that the two media are mixed more slowly and non-uniformly as is common. It is necessary to improve the mixing speed and uniformity of the two media.
