Flue gas desulfurization and denitrification device

The utility model belongs to the technical field of desulfurization and denitrification, and discloses a flue gas desulfurization and denitrification device, which comprises a desulfurization and denitrification tower body, a support is connected to the outside of the desulfurization and denitrification tower body, and a gas inlet pipe and a water inlet pipe are respectively communicated and connected to two sides of the desulfurization and denitrification tower body. A desulfurization and denitrification agent and flue gas are guided into the desulfurization and denitrification tower body through a spray head and a gas inlet pipe respectively, so that the desulfurization and denitrification agent and the flue gas enter the box body through through grooves in the top and the bottom of the box body respectively, and then a motor is started to drive a stirring plate to rotate through a rotating shaft and a bearing; according to the flue gas desulfurization and denitrification device, the stirring plates stir th
