Referring to fig. 1, an example vertical circulating flue gas spray tower includes: the tower body 1, the air inlet pipe 2, the spray pipe 3, the spray head 4, the demister 5, the spray liquid circulation box 6, the baffle 7, the filter plate 8, the pump body 9, the liquid supplementing box 10 and the liquid supplementing pipe 11. Wherein: the tower body 1 is of a cylindrical structure which is vertically arranged, the upper end of the tower body is provided with an air outlet 12, and the treated flue gas is discharged from the air outlet 12 and enters the next treatment process. The air inlet pipe 2 is arranged at the lower part of the tower body 1, and the part of the air inlet pipe 2 positioned in the tower body 1 is provided with air outlet holes so as to uniformly distribute air into the tower body 1.
The spray pipe 3 is arranged in the upper space in the tower body 1, the spray head 4 is fixedly connected to the spray pipe 3, and the spray head 4 is arranged downwards to spray the spray liquid downwards. The spray liquid circulation box 6 is arranged outside the tower body 1 and is communicated with a permeable window on the outer wall of the tower body 1, the permeable window is arranged at the lower part of the outer wall of the tower body 1, and a baffle 7 and a filter plate 8 are arranged in the permeable window. Wherein: the baffle 7 is fixed at the lower part of the water permeable window, and the side wall and the bottom surface of the baffle 7 are fixedly connected with the water permeable window in a sealing way. The filter plates 8 are vertically connected to the upper surface of the baffle plate 7, and the rest space of the permeable window is covered, so that the spray liquid at the bottom of the tower body 1 enters the spray liquid circulation box 6 after being filtered by the filter plates 8.
The other end of the spray pipe 3 penetrates out of the tower body 1 and then is communicated with the spray liquid circulation box 6 through the pump body 9, the pump body 9 is connected with a driving motor, the driving motor enables the pump body to operate, and spray liquid in the spray liquid circulation box 6 and the liquid supplementing box 10 is conveyed into the spray head 4 through the spray pipe 3 for spraying.
