Operation principle of the present invention:
(1), flue gas is assisted the operation principle that tower 2 purifies through first king-tower 1 and first: first urceolus advances mouth 1-1-3 and is communicated with the first air inducing flue 13, and the outlet of first flue 5 is communicated with first chimney bridge 14; Flue gas advances mouth 1-1-3 by the first air inducing flue 13 through first urceolus and enters between the first outer cylinder body 1-1 and the first inner barrel 1-2, and decline enters in first king-tower awl tube 1-4 in a clockwise direction, flue gas is finished a wet method sulphur removing and dust removing and is purified in first king-tower awl tube 1-4, water inlet in first king-tower 1 is by first king-tower entering water electromagnetic valve 1-11 control, water is entered in first king-tower awl tube 1-4 by two first king-tower water inlet pipe 1-3, control water level in first king-tower 1 by the double-colored high and low water alarm 1-8 of first king-tower and the board-like high and low water alarm 1-7 of first king-tower, as surpassing the control water level, the first king-tower blowdown magnetic valve 1-9 opens automatically and carries out blowdown, and blowdown is to removing pit; If be lower than the control water level, the first king-tower entering water electromagnetic valve 1-3 opens and carries out moisturizing (moisturizing source boiler blowdown water).Because dextrorotation air inducing case 1-5 malleation dynamic action forces flue gas to rise, flue dust is counterclockwise to rise in the first inner barrel 1-2, and flue dust rises the back head-on collision on the first electronic accent air curtain 1-6, regulates flue gas flow by the first electronic accent air curtain 1-6; Flue dust is through dextrorotation air inducing case 1-5, first flue 5, second flue 7 enters the first auxilliary tower 2, flue gas descends in the first auxilliary tower 2, finish the secondary wet process desulfurization dust separation, water enters first by the first auxilliary tower water inlet pipe 2-3 through the first auxilliary tower entering water electromagnetic valve 2-9 and assists in the tower slower conical tube 2-2, water level in the first auxilliary tower slower conical tube 2-2 is by the first auxilliary double-colored high and low water alarm 2-7 of tower and the first auxilliary column plate type high and low water alarm 2-6 control, surpass the control water level as the water level among the first auxilliary tower water tank 2-3, the first auxilliary tower magnetic valve 2-8 opens automatically and carries out blowdown, and blowdown is to removing pit; Flue dust in the first auxilliary tower 2 reaches constant weight, and the grey device 2-5 of first lock opens deashing automatically; If the water level among the first auxilliary tower water tank 2-3 is lower than the control water level, the first auxilliary tower entering water electromagnetic valve 2-9 opens and carries out moisturizing (moisturizing source boiler blowdown water).Flue gas rising through double purification enters first chimney bridge 14 through second flue 7, first flue 5, enters in the atmosphere finally by chimney.
(2), flue gas is assisted the operation principle that tower 4 purifies through second king-tower 3 and second: second urceolus advances mouth 3-1-3 and is communicated with the second air inducing flue 15, and the outlet of the 3rd flue 9 is communicated with second chimney bridge 16; Flue gas advances mouth 3-1-3 by the second air inducing flue 15 through second urceolus and enters between the second outer cylinder body 3-1 and the second inner barrel 3-2, and enter in second king-tower awl tube 3-4 counterclockwise to descend, flue gas is finished a wet method sulphur removing and dust removing and is purified in two king-towers awl tube 3-4, water inlet in second king-tower 3 is by second king-tower entering water electromagnetic valve 3-11 control, water is entered in second king-tower awl tube 3-4 by two second king-tower water inlet pipe 3-3, control water level in second king-tower 3 by the double-colored high and low water alarm 3-8 of second king-tower and the board-like high and low water alarm 3-7 of second king-tower, as surpassing the control water level, the second king-tower blowdown magnetic valve 3-9 opens automatically and carries out blowdown, and blowdown is to removing pit; If be lower than the control water level, the second entering water electromagnetic valve 3-11 opens and carries out moisturizing (moisturizing source boiler blowdown water).Because left-handed air inducing case 3-5 malleation dynamic action forces flue gas to rise, flue dust rises in a clockwise direction in the second inner barrel 3-2, and flue dust rises the back head-on collision on the second electronic accent air curtain 3-6, regulates flue gas flow by the second electronic accent air curtain 3-6; Flue dust is through left-handed air inducing case 3-5, the 3rd flue 9, the 4th flue 11 enters the second auxilliary tower 4, flue gas descends in the second auxilliary tower 4, finish the secondary wet process desulfurization dust separation, water enters second by the second auxilliary tower water inlet pipe 4-3 through the second auxilliary tower entering water electromagnetic valve 4-9 and assists in the tower slower conical tube 4-2, water level in the second auxilliary tower slower conical tube 4-2 is by the second auxilliary double-colored high and low water alarm 4-7 of tower and the second auxilliary column plate type high and low water alarm 4-6 control, surpass the control water level as the water level among the second auxilliary tower water tank 4-3, the second auxilliary tower magnetic valve 4-8 opens automatically and carries out blowdown, and blowdown is to removing pit; Flue dust in the second auxilliary tower 4 reaches constant weight, and the grey device 4-5 of second lock opens deashing automatically; If the water level among the second auxilliary tower water tank 4-3 is lower than the control water level, the second auxilliary tower entering water electromagnetic valve 4-9 opens and carries out moisturizing (moisturizing source boiler blowdown water).Flue gas rising through double purification enters second chimney bridge 16 through the 4th flue 11, the 3rd flue 9, enters in the atmosphere finally by chimney.
