Embodiment

[0035] This embodiment provides a kind of sludge cracking treatment method, such as figure 2 shown, including the following steps:

[0036] S101. Put the oil sludge into the feed pretreatment device, and the feed pretreatment device heats the oil sludge while conveying the material to evaporate and crack the moisture and light components in the sludge to obtain heavy oil residue;

[0037] S102. The feed pretreatment device outputs the heavy oil residue from its outlet to the high temperature plasma melting device;

[0038] S103. The high-temperature plasma melting device melts the input heavy oil slag with a high-temperature plasma torch, and transforms it into vitreous waste slag containing CO 2 , CO and H 2 of synthetic gas.

[0039] Among them, the oil sludge cracking treatment device, such as figure 1 shown, including:

[0040] The feed pretreatment device 1 is used to heat the oil sludge to evaporate and crack the moisture and light components in it to obtain heavy ...

Abstract

The invention discloses an oil sludge cracking treatment method, which relates to the technical field of harmless treatment of solid waste, comprising: putting the oil sludge into a feed pretreatment device, and the feed pretreatment device heats the oil sludge while transporting materials to make the water and light in the sludge The heavy components are evaporated and cracked by heat to obtain heavy oil residue; the feed pretreatment device outputs the heavy oil residue from its outlet to the high-temperature plasma melting device; the high-temperature plasma melting device processes the input heavy oil residue High-temperature plasma torch melting, transforming into vitreous waste slag and containing CO 2 , CO and H 2 of synthetic gas. The invention has the advantage of high degree of harmless treatment.

Description

technical field [0001] The invention relates to the technical field of harmless treatment of solid waste, in particular to an oil sludge cracking treatment method. Background technique [0002] Oil sludge is solid waste produced during crude oil extraction, gathering and transportation, refining, and refinery sewage treatment. It contains a large amount of residual oil, benzene series, phenols, anthracene and other foul-smelling toxic substances and a large number of pathogenic bacteria, Toxic and harmful substances such as heavy metals, polychlorinated biphenyls, and dioxins. In addition, oil sludge also has the characteristics of high viscosity, poor fluidity, and difficult separation of oil and soil. [0003] Direct incineration is currently the main method of oil sludge disposal, but due to the presence of heavy components such as asphalt, the incineration flue gas contains a large amount of unburned toxic and harmful components, which can easily cause secondary polluti...
