Embodiment 1
[0035] Catalyzed gasoline soda residue in a refinery, in which COD is 3.21×10 5 mg / L, the sulfide is 1.76×10 4 mg / L. with attached figure 1 The acidification reaction device is used for acidification treatment. The height-to-diameter ratios of the reaction tower and the condensation tower are 15 and 10 respectively; The angle is 30° to connect with the two towers, the connecting port of the condensing tower is lower than the connecting port of the reaction tower; the lower connecting pipe is connected to the two towers at a horizontal angle of 45°, and the connecting port of the condensing tower is higher than the connecting port of the reaction tower. The acidification reaction tower adopts a cylindrical reaction tower with a conical upper end, one end of the suction pipe is connected with the conical surface of the conical tower wall at the upper end of the reaction tower, and there are 6 suction pipes, which are evenly and symmetrically distributed on the periphery of the...
Embodiment 2
[0037] A refinery liquid hydrocarbon alkali slag, in which COD is 7.97×10 4 mg / L, sulfide is 4×10 3 mg / L. with attached figure 1 The acidification reaction device is acidified. The height-to-diameter ratios of the reaction tower and the condensation tower are 18 and 12 respectively; the diameters of the upper connecting pipe and the lower connecting pipe are 0.8 times the diameter of the reaction tower, and the angle between the upper connecting pipe and the horizontal angle is 50° °Connected to the two towers, the connecting port of the condensing tower is lower than the connecting port of the reaction tower; the lower connecting pipe is connected to the two towers at an angle of 50° to the horizontal, and the connecting port of the condensing tower is higher than the connecting port of the reaction tower. The acidification reaction tower adopts a cylindrical reaction tower, the upper end of which is set in a conical shape, and one end of the suction pipe is connected with ...
