Background
Coal is always the main primary energy in China and accounts for about 60% of the total primary energy consumption in China. The coal-fired boiler is used as main equipment for coal combustion and utilization, and is widely applied to industries such as thermal power plants, petroleum refining and coking; during the operation process, a large amount of pollutants such as particulate matters, SOx, NOx and the like are discharged, and denitration, desulfurization and particulate matter removal are generally needed; the wet desulphurization comprises the processes of lime/gypsum method, ammonia method, magnesium oxide method and the like, is the main method for flue gas desulphurization, and accounts for more than 90% of the domestic desulphurization market.
However, the flue gas formed after wet desulphurization has a low temperature (45-55 ℃), has a high moisture content, and generally forms a white smoke phenomenon at an outlet after being discharged from a chimney, so that colored smoke plume and gypsum rain are formed; a large amount of soluble particulate matters contained in the exhaust smoke are also one of main sources of haze formation, so that the health of people is damaged; a large amount of water vapor contained in the discharged smoke can escape along with the discharged smoke, so that the great waste of water resources is caused, and the influence on the local ecological environment is caused, especially in drought and water-deficient places.
In order to realize environmental protection, the coal-fired boiler needs to be subjected to white elimination treatment before smoke is discharged, so that the generation of white smoke is inhibited. The mechanism of the smoke whitening is that wet smoke is changed from a saturated state to an unsaturated state through temperature rise, so that the phase change and condensation of water vapor at the outlet of a chimney are prevented, the formation of liquid water at the outlet of the chimney is inhibited, and the formation of white smoke is avoided.

The application number 201910672189.1 of the Chinese utility model discloses a smoke whitening device and method, which realizes the dehydration and whitening treatment of smoke by arranging a circulating water pipeline to connect a cooling tower and a GGH heat exchanger. Although the technical scheme can effectively control the white smoke elimination of the flue gas of the coal-fired boiler, solve the problem of white smoke pollution, reduce the system operation cost and realize energy conservation and consumption reduction, the water resource waste can be caused because the water vapor in the flue gas is not recovered.
The application number 201810669287.5 discloses a coal-fired flue gas white elimination, emission reduction and waste heat deep recovery device and system, and by arranging a flue gas waste heat recovery unit and a flue gas white elimination unit, water vapor in flue gas is condensed and recovered, the moisture content of discharged smoke is reduced, and the formation of white smoke is reduced. However, because of the requirement and attention on ultralow emission of the coal burning boiler, when the wet desulphurization is carried out on the flue gas dedusted by the electrostatic precipitator, the concentration of the particulate matters in the flue gas rises, the implementation of the technical scheme can not realize the secondary removal of the particulate matters, and the ultralow emission of the particulate matters in the flue gas can be met only by further installing wet electric dedusting equipment in the follow-up process, so that the actual requirement can not be met.
