Description

Technical Field

[0001] The invention relates to the technical field related to heat exchangers, and in particular to an energy-saving heat exchanger for refining zinc powder. Background Art

[0002] In the process of zinc powder refining, a fluidized bed furnace is required to roast the material at high temperature. When the fluidized bed furnace is used, a large amount of high-temperature flue gas will be generated. Since the high-temperature flue gas contains a large amount of heat, direct discharge will lead to heat loss. Therefore, a heat exchanger is used in the prior art to recycle the heat in the high-temperature flue gas.

[0003] The existing Chinese patent document with the announcement number CN219757048U discloses a flue gas heat exchanger, which includes: a first heat exchange furnace, wherein the first heat exchange furnace has a first heat exchange channel extending vertically, wherein the first heat exchange channel is used to receive flue gas, wherein the flue gas contains smoke dust; a settling bin, wherein the settling bin is located below the first heat exchange furnace and is connected to the lower end of the first heat exchange channel so that the smoke dust in the first heat exchange channel is settled in the settling bin; a second heat exchange furnace, wherein one end of the second heat exchange furnace is connected to the settling bin, wherein the second heat exchange furnace has a second heat exchange channel connected to the settling bin so that the smoke passes through the first heat exchange channel and the settling bin and then flows into the second heat exchange channel;

[0004] However, the heat exchange channel used to recover the flue gas heat in the above-mentioned solution cannot form a self-cleaning effect on the side walls of the channel, which causes smoke to adhere to the side walls of the heat exchange channel. The adhesion of smoke will affect the heat exchange efficiency of the heat exchange channel, thereby resulting in a decrease in the utilization rate of the flue gas heat. For this reason, the present invention proposes an energy-saving heat exchanger for refining zinc powder to solve the above-mentioned problem. Summary of the invention
