Background
At present, most domestic power station boilers adopt a wet desulphurization system to remove sulfur dioxide, the process has high sulfur dioxide desulphurization efficiency and stable operation, after the wet desulphurization of the flue gas, the moisture content of the flue gas is generally up to 13-15 percent, even up to 20 percent, the temperature of the flue gas is low (between 50 and 55 percent), the desulfurized flue gas enters air, when the water vapor in the flue gas is in a supersaturated state, partial water vapor is condensed and fogged, atomized fine liquid drops are formed, and the phenomenon of 'white smoke' can occur. Especially in winter, the white smoke phenomenon is not only aggravated, but also causes greater resource waste because water is also a resource.
Although the desulfurization system adopts the demister to reduce the humidity of the discharged smoke, a large amount of water resources are still discharged to the atmosphere through the chimney of the desulfurization system, the haze is easily caused under the specific climatic conditions, the environmental pollution is caused, and the water resource waste is further caused. According to the cause of 'colored smoke plume', the current smoke whitening process mainly has 2 directions: 1. the moisture in the flue gas is reduced; 2. the emission temperature of the flue gas is improved; 3. the flow velocity of flue gas is reduced, and secondary entrainment is reduced; 4. a smoke tower integration technology is adopted; 5. introducing hot air for mixing and discharging. The reduction of moisture in flue gas can be realized by the following measures:
(1) reducing the temperature of raw flue gas entering the FGD system through a flue gas heat exchanger;
(2) adding a tube bundle demister into the desulfurized clean flue gas to remove most of liquid drops;
(3) adding a wet electric dust collector to the desulfurized clean flue gas to remove most fine liquid drops;

the final emission temperature of the flue gas is improved, the emission temperature of the clean flue gas can reach about 80 ℃ through GGH, the heated flue gas is in an unsaturated state, and white smoke cannot be formed after the flue gas is discharged through a chimney. The current main smoke feather elimination technology is a direct heating method and an indirect heating method, which only eliminate visual influence and do not reduce the moisture content of smoke; the cooling condensation method has high requirement on a cold source; the condensation reheating method can thoroughly realize the white elimination of the flue gas, but the equipment is relatively complex; the solution absorption method has high cost and strong corrosivity; the effects of removing water vapor are not achieved by the cyclone wet removing method, the demister is modified, the wet electric dust remover is installed, and the white removing capability is limited.
