Novel oily sludge treatment method and system

Abstract

The invention discloses a novel oily sludge treatment method and system. Treatment of oily sludge is divided into three thermal cracking stages, and one specific problem of the oily sludge is solved in each stage, so that the oily sludge can be treated more effectively, and the oily sludge become harmless. Another key point is the structural design of a matched thermal cracking machine, and a conventional external heating mode is changed into an internal radiation heating mode, so that the coking problem of the oily sludge on the inner walls of equipment is effectively inhibited, and the equipment can operate normally. Meanwhile, two purposes of water removal and oil removal are achieved, so that normal operation of the treatment equipment is ensured while the oily sludge is treated to bequalified. The whole process is modularly designed, the system is easy to for assembly, maintenance and upgrading improvement, and the system also has the advantages of low maintenance cost and high automation degree.

Description

technical field [0001] The invention relates to the technical field of oily sludge treatment, in particular to a new oily sludge treatment method and system. Background technique [0002] Under the increasingly severe pressure of the environmental protection situation, the pollution caused by the oily sludge accumulated in oil fields and refining and chemical enterprises has been highly valued by the state. Enterprises need to properly dispose of the oily sludge generated in production activities. At home and abroad, the current treatment methods for oily sludge reaching the standard are: 1. Enter the incinerator for high-temperature incineration, and the remaining products that meet the standard after incineration are landfilled or fired into bricks. This treatment method is costly and coking will affect the incinerator. Normal operation, energy cannot be effectively recovered, if the oily sludge has a high moisture content, the temperature in the furnace will drop after en...

AI Technical Summary

Problems solved by technology

The treatment of oily sludge in the existing technology will cause a series of problems such as damage to the treatment equipment and substandard treatment results

Moreover, the equipment used in the original sludge drying process is externally heated to dry the sludge; the resulting problem is that the oily sludge is agglomerated and coked on the inner wall of the equipment, which gradually blocks the equipment, making the equipment unable to operate normally or even completely scrapped
