Abstract

The invention relates to a method for separating and recovering carbon from a pyrolysis residue of sludge containing oil, which is applied to the technical field of oil extraction waste water and oil sludge pollution treatment. The method comprises the following steps of: simultaneously adding the pyrolysis residue and an activating agent into a stirrer and uniformly stirring; then adding an obtained mixture into an activation furnace for treating for 1-4 hours; flushing the activated residue into a first reaction pot by utilizing a water replenishing system and adding a test solution A, wherein the mass ratio of the activated pyrolysis residue to the test solution A is (1:2)-(1:15); introducing into hydrogen and rinsing the residue with water for 3-8 times; flushing the residue into a second reaction pot 7 and adding a test solution B, wherein the mass ratio of the pyrolysis residue subjected to the treatment procedure of the test solution A to the test solution B is (1:3)-(1:12); introducing into steam; flushing the residue into a carbon storage slot, and starting a carbon storage slot stirrer to mix carbon and water; starting a centrifugal machine for dewatering; and adding the mixture into a dry ball mill to pulverize to 120-200 meshes. The invention has the advantages of good separation and recovery effects, small occupation area, convenient operation, economy, feasibility, no secondary pollution, carbon resource recovery, low energy consumption and low running cost.

Description

technical field [0001] The invention relates to the technical field of oil production wastewater and oil sludge pollution treatment, in particular to a method for separating and recovering carbon from oily sludge pyrolysis residue. Background technique [0002] The exploration of new methods for thermochemical treatment and resource utilization of oily sludge represents the advanced direction and development trend in the field of solid waste treatment. The oily sludge pyrolysis residue is the waste residue produced after the oily sludge from the oil field is processed by high temperature pyrolysis, and is usually called the pyrolysis residue, which is the pyrolysis residue referred to in the present invention. The carbon content in the pyrolysis residue is about 40%, which has a high value of separation and recovery. Compared with the pyrolysis of oily sludge, which is aimed at the organic components, the resource utilization of pyrolysis residues is mainly aimed at the ino...
