Abstract

The invention discloses an acidification reaction device and an acidification method for oil refining alkali slag. The acidification reaction device includes an acidification reaction tower and a condensation tower. A tubular gas distributor is arranged at the bottom of the acidification reaction tower body, and a condensation device is arranged on the surface of the condensation tower body. The two towers are sealed and communicated by the upper connecting pipe and the lower connecting pipe respectively, thus forming an air-lift external circulation reaction channel between the two towers; the tubular gas distributor is a self-priming tubular gas distributor, and its A hollow shaft is connected to the lower end of the hollow shaft, and a motor is connected to the lower end of the hollow shaft, which can rotate the hollow shaft and the tubular gas distributor; a bubble tube is arranged on the periphery of the tower body, and one end of the bubble tube is sealed with the wall of the acidification reaction tower, and the other end is It is tightly connected with the gas input pipeline. The invention also provides an acidification method of the oil refining alkali residue using the acidification reaction device. Compared with the prior art, the present invention has the characteristics of simple device structure, high acidification efficiency, good defoaming effect, and prevention of device and pipeline blockage.

Description

technical field [0001] The invention belongs to the field of environmental protection wastewater treatment, and in particular relates to an acidification reaction device of oil refining alkali residue with functions of defoaming and anti-clogging and an acidification method thereof. Background technique [0002] In the process of alkali washing and refining of oil products in refineries, alkaline waste liquid containing high concentrations of pollutants will be produced, which is called alkali residue, and the discharge of COD, sulfide and phenol accounts for 40% of the discharge of such pollutants in the refinery ~50% or more. If these alkali residue waste liquids are directly discharged, they will seriously pollute the environment and seriously corrode equipment. In recent years, with the increasingly complete and strict national environmental protection regulations and standards, as well as people's increasing voices for improving environmental quality, more and more att...
