[0010] Depend on figure 1 As shown, the device of the present invention mainly includes a desulfurization reaction main tower 3, a gas-solid separator 5 and an ash hopper 6. The desulfurization reaction main tower 3 is connected with the gas-solid separator 5 by connecting the flue 4, and the gas-solid separator The lower part of 5 is arranged with an ash hopper 6, and the pneumatic chute 7 is arranged at the bottom of the ash hopper 6, and the desulfurization ash outlet 8 and the return device 9 are arranged on the pneumatic chute 7, and the dirty flue gas is divided into two and respectively imported from the flue gas 1 enters the main desulfurization reaction tower and flue gas inlet 2 enters the ash hopper 6 is the desulfurization reaction auxiliary tower. After the dirty flue gas is mixed and reacted with water, desulfurizing agent and circulating materials in the desulfurization reaction main tower, the acid gas in it is effectively removed, and the dirty flue gas enters...
