The specific embodiment:
Three groups of spray equipments that flow-disturbing body desulfurizing tower of the present utility model is installed by tower body 1, within it 2, two groups of folded plate type air deflectors 3, two groups of flow-disturbing body devices 4 and gas-liquid separation device 5 are formed; Gas-liquid separation device is on tower body top, the gas-liquid separation device below is one group of spray equipment, this group spray equipment below is one group of flow-disturbing body device, this flow-disturbing body device below is one group of folded plate type air deflector, and this folded plate type air deflector below is second group of spray equipment, and this spray equipment below is second group of flow-disturbing body device, this flow-disturbing body device below is second group of folded plate type air deflector, this folded plate type air deflector below is the 3rd a group of spray equipment, and sewage draining exit 1-1 is arranged at the tower body bottom, as shown in Figure 1.
Tower body except that folded plate type air deflector, flow-disturbing body device, gas-liquid separation device installation position are equipped with step 1-6 and gas inlet and outlet 1-3,7, manhole 1-4, doctor solution import 1-5, soiling solution outlet 1-1 all be shiny surface as shown in Figure 2, very convenient to preservative treatment in the equipment.Its device diameters size, porting, doctor solution import are to decide according to device processes tolerance size.Its folded plate type air deflector 3, flow-disturbing body device 4, gas-liquid separation device 5, spray equipment 2 all are designed to several body, treat behind the main equipment installation in position to enter to make up from manhole 1-4 to install or dismounting and changing during maintenance.
