Wet flue gas desulfurization tower

The invention provides a wet flue gas desulfurization tower. The wet flue gas desulfurization tower comprises a vertical type tower, wherein the vertical type tower is internally provided with a plurality of layers of fillers and a plurality of layers of spraying devices; the plurality of layers of spraying devices are connected with a first spraying water pump; the wet flue gas desulfurization tower further comprises a horizontal type tower; a draught fan is arranged at an inlet of the horizontal type tower; the horizontal type tower is internally provided with at least 5-10 layers of spraying devices; an outlet of the horizontal type tower is in butt joint with the bottom of the vertical type tower; the spraying devices in the horizontal type tower are connected with the first spraying water pump; a wastewater collection tank is arranged below the horizontal type tower and is used for collecting wastewater generated by the spraying of the spraying devices. According to the wet flue gas desulfurization tower, the horizontal type tower and the 5-10 layers of spraying devices are additionally arranged, and the wet flue gas desulfurization tower is convenient to mount and arrange; the processing distance of smoke is lengthened and the desulfurization is thorough; compared with the prior art, the horizontal type tower is convenient to arrange; the processing distance of the smoke can be changed randomly; the wet flue gas desulfurization tower has the advantages of low investment and good effect.
