Abstract

The invention discloses an oil refining alkaline residue acidification reactor and an acidification method thereof. The reactor comprises an acidification reaction tower and a condensing tower. The bottom of the acidification reaction tower is provided with a tubular gas distributor. A condensing device is arranged on the surface of the condensing tower. Two towers are communicated with each other through an upper communication pipe and a lower communication pipe, and thus an airlift type external circulation reaction channel is formed between two towers. The tubular gas distributor is a self-suction type tubular gas distributor, the lower end of the tubular gas distributor is connected to a hollow shaft, and the lower end of the hollow shaft is connected to a motor, which can drive the hollow shaft and the tubular gas distributor to rotate. The periphery of the reaction tower is provided with a bubble sucking pipe, one end of the bubble sucking pipe is hermetically connected to the wall of the acidification reaction tower, and the other end is hermetically connected to a gas input pipeline. The invention also provides an oil refining alkaline residue acidification method using the provided acidification reactor. Compared with the prior art, the provided reactor and method have the characteristics that the structure is simple, the acidification efficiency is high, the antifoaming effect is good, and the obstruction of pipe and reactor is prevented.

Description

technical field [0001] The invention belongs to the field of environmental protection wastewater treatment, and in particular relates to an acidification reaction device and an acidification method for oil refining alkali slag with functions of defoaming and anti-clogging. 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. ...
