[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Such as Figures 1-3As shown in the figure, a flue gas desulfurization and denitrification device includes a shunt-type easy-to-clean water storage tank 1. The upper outer surface of the shunt-type easy-to-clean water storage tank 1 is provided with a self-separating flue gas inlet box 2. The upper outer surface of the self-separating flue gas inlet box 2 is provided with an atomizing desulfurization and denitrification box 3. The upper outer surface of the atomizing desulfurization and denitrification box 3 is provided with an atomizing installation box 4. The upper outer surface of the atomizing installation box 4 is provided with an atomizing spray cover plate 5. The middle of the upper end of the atomizing spray cover plate 5 is provided with a flue gas discharge pipe 6. The shunt-type easy-to-clean water storage tank 1 includes a support base 101, a first water storage tank 102, a second water storage tank 103, a three-way connecting pipe 104, a cleaning water detector 105, a shunt box 106, a conical guide plate 107, and an electromagnetic shunt valve 108. The self-separating flue gas inlet box 2 includes a flue gas separation outer shell 201, an inlet pipe 202, a support frame 203, a flue gas dispersion column 204, a flue gas connecting pipe 205, and a conical hydrophobic cover 206.

[0024] It should be noted that the present utility model is a flue gas desulfurization and denitrification device. When in use, first, the split-type convenient cleaning water storage tank 1 supplies water to the atomizing spray cover plate 5 in the atomizing installation box 4. While supplying water, the flue gas enters the atomizing desulfurization and denitrification box 3 through the self-separating flue gas inlet box 2 and is contacted with the treated water atomized by the atomizing spray cover plate 5. After the absorption work is completed, the treated water flows back to the split-type convenient cleaning water storage tank 1, and the filtered clean flue gas is discharged through the flue gas discharge pipe 6. The split-type convenient cleaning water storage tank 1 provided includes a support base 101, a first water storage tank 102, a second water storage tank 103, a three-way connecting pipe 104, a cleaning water detector 105, a split box 106, a conical guiding plate 107, and an electromagnetic flow dividing valve 108. When in use, first, the first water storage tank 102 and the second water storage tank 103 inside the support base 101 are filled with treated water. After filling, the electromagnetic valve on the second water storage tank 103 is closed through the three-way connecting pipe 104, and the treated water inside the first water storage tank 102 is pressurized and transported. The used treated water is returned to the first water storage tank 102 through the conical guiding plate 107 inside the split box 106 and the electromagnetic flow dividing valve 108. After the cleaning water detector 105 detects that the quality of the treated water does not meet the usage requirements, the electromagnetic valve on the second water storage tank 103 is opened and the electromagnetic valve on the first water storage tank 102 is closed, and the second water storage tank 103 takes over the work. After the second water storage tank 103 supplies water, the treated water inside the first water storage tank 102 can be replaced. When in use, the treated water can be replaced without stopping the equipment, which not only has good working efficiency but also ensures the treatment effect of the treated water. The self-separating flue gas inlet box 2 provided includes a flue gas separation housing 201, an inlet pipe 202, a support frame 203, a flue gas dispersion column 204, a flue gas connecting pipe 205, and a conical hydrophobic cover 206. When in use, first, the flue gas is injected into the flue gas dispersion column 204 through the inlet pipe 202 and the flue gas connecting pipe 205. The rotating wheel inside the flue gas dispersion column 204 completes the work of diffusing the flue gas around. After the flue gas is diffused, the filtration of the flue gas is completed through the contact between the treated water and the flue gas. The used water is guided by the conical hydrophobic cover 206 to prevent the treated water from entering the flue pipe. When in use, it can not only ensure the uniformity of the flue gas release so that it can be repeatedly contacted with the treated water, but also prevent the treated water from entering the flue pipe when in use.
