Description

Technical Field

[0001] The utility model relates to a flue gas processing device, in particular to a high-temperature flue gas cooling and dust removal integrated device. Background Art

[0002] The traditional method of treating flue gas is to send the hot flue gas into a low-temperature environment through equipment such as cooling towers or heat exchangers to reduce the temperature of the flue gas through heat exchange; this process can be carried out alone or in combination with the condensation of water vapor.

[0003] Dust removal usually uses physical filtration, electrostatic precipitator or wet dust removal.
