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. Attached figure 1 The acidification reactor is used for acidification treatment. The acidification reactor 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 reactor. The distribution is distributed around the acidification reactor. The ratio of height to diameter of the tower body of the acidification reactor is 15, the ratio of the diameter of the diversion cylinder to the tower body is 0.7, the height ratio of the height of the diversion cylinder to the height of the tower body is 0.6, and the bottom of the diversion cylinder The ratio of the gap height to the bottom of the tower body and the diameter of the guide tube is 1:2. The guide tube is set in 3 sections with an interval of 15mm. The gas distribution hole diameter of the tub...

Abstract

The invention discloses an oil refining alkaline residue acidification reactor with an antifoaming function and an antifoaming method. The acidification reactor comprises an enclosed tower for containing liquid, a guide cylinder is arranged in the tower, a self-suction tubular gas distributor is arranged on the bottom of the guide cylinder, the lower end of the tubular gas distributor is connected to a hollow shaft, the hollow shaft and tubular gas distributor can rotate, while a gas inlet pipe maintains still, the hollow shaft and the gas inlet pipe are connected through a sealing cavity; the periphery of the tower is provided with a bubble absorbing pipe, and when bubbles are generated in the tower, under the effect of the gas distributor, bubbles are returned from the upper end of the reactor to the reaction tower through the bubble absorbing pipe and the gas inlet pipe. The invention also provides an antifoaming method using the reactor during the acidification process of oil refining alkaline residues. On the basis that sufficient gas is provided, the foams can be rapidly and efficiently removed, the phenomenon of flooding and entrained liquid is avoided, and compared with the prior art, the provided reactor and method have the characteristics of simple device structure, high acidification efficiency, and good antifoaming effect.

Description

technical field [0001] The invention belongs to the field of environmental protection wastewater treatment, and in particular relates to an acidification reactor for oil refining alkali residue with a defoaming function and a defoaming method. Background technique [0002] In the process of alkaline cleaning and refining of oil products in refineries, alkaline waste liquid containing high concentrations of pollutants is called alkali residue, and its COD, sulfide and phenol emissions account for 40% of the emissions of such pollutants in refineries ~50% or more. If these alkali slag waste liquids are discharged directly, they will seriously pollute the environment and severely corrode the equipment. In recent years, with the increasingly complete and strict national environmental protection regulations and standards, and people's calls for improving environmental quality, more and more attention has been paid to the treatment of alkali slag. [0003] At present, the common...
