Circular desulfurizing and denitrifying dust removing device

[0027] Embodiment one:

[0028] like figure 1 A cycle desulfurization, denitrification and dust removal device shown at least includes a flue inlet 2 and a flue exhaust 26, and also includes

[0029] The dust removal reaction chamber 13 is provided with a first inlet, a first outlet and a second outlet, and the described flue inlet 2 communicates with the first inlet;

[0030] The desulfurization and denitrification reaction chamber 14 is provided with a second inlet, a third inlet, a third outlet and a fourth outlet, the second inlet communicates with the first outlet, and the third outlet communicates with the exhaust duct 26 and is provided with an air pump 4 The circulating flue 3 is connected to the inlet flue 2;

[0031] The condensation tower 17 is provided with a fourth inlet, a fifth inlet, a sixth inlet and a fifth outlet, wherein the fourth inlet is connected to the second outlet; the fifth inlet is connected to the fourth outlet;

[0032] The heat exchange tower 18

[0038] Embodiment two:

[0039] like figure 1 and figure 2 The difference between the circulating desulfurization, denitrification and dust removal device shown in Embodiment 1 is that the water pipe 6 connected to the seventh outlet and the water pipe 6 connected to the eighth outlet are also provided with an electrostatic generator 7.

[0040] Preferably, the static electricity generating device 7 includes an inner ring 19, an outer convex structure 20, an inner convex structure 21, an outer ring 22, a shaft center 23, a connecting rod 24 and blades 25; the two ends of the connecting rod 24 are respectively It is fixedly connected with the shaft center 23 and the inner surface of the inner ring 19, and the blade 25 is fixedly connected with the shaft center 23 and arranged between adjacent connecting rods 24; the outer surface of the inner ring 19 is provided with a convex structure 20; the outer ring 22 is in contact with the inner ring 19 through the inner convex structure

[0046] Embodiment three:

[0047] like figure 1 and figure 2 The shown circulating desulfurization, denitrification and dust removal device differs from Embodiment 1 in that: the lower part of the spray pipe 8 is detachably connected with a spray head 9, and the lower bottom surface of the spray head 9 is as high as Into the flue 2.

[0048] Preferably, the outlet of the reagent storage chamber 10 is provided with a water valve 11 .

[0049] It is preferred that all said components are skid-mounted within the housing.

[0050] In actual use, the lower part of the spray pipe 8 is detachably connected with the shower head 9, so that the hot water with static electricity is sprayed through the shower head 9, and the water molecules are highly active at high temperature and have electrostatic adsorption binding. Dust particles have a strong ability to achieve a good dust removal effect. Similarly, when the flue gas enters the desulfurization and denitrification reaction chamber
