The invention provides a process method for sintering flue gas desulfurization, denitration, dust removal, whitening, and whitening. After heat exchange, the heated sintering raw flue gas is heated to 320 ℃ by the supplementary burner, and then ammonia gas is evenly injected into it, and then enters the denitration reactor for flue gas denitration, and the high temperature sintering flue gas after denitration passes through the rotary The flue gas heat exchanger transfers heat to the sintering raw flue gas and then enters the ammonia desulfurization system for cooling, dust removal and desulfurization. The clean flue gas enters the heating section of the flue gas water-mediated heat exchanger. The invention reduces the energy consumption required for denitrification of the sintering flue gas, reduces the temperature and water content of the saturated flue gas after desulfurization, and utilizes a rotary flue gas heat exchanger to increase the temperature of the flue gas after desulfurization to realize the whitening of the flue gas, and the process route is simple and easy to operate. . |
