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 a sludge splitting decomposition treatment method, and relates to the technical field of solid waste harmful treatment. The sludge splitting decomposition treatment method comprises the steps that sludge is thrown into a feeding pretreatment device, when the feeding pretreatment device conveys materials, sludge is heated, water and light components in the sludge are heated,evaporated and subjected to splitting decomposition, and heavy oil residues are obtained; the feeding pretreatment device outputs the heavy oil residues to a high-temperature plasma fusion device from a discharging port of the feeding pretreatment device; and the high-temperature plasma fusion device conducts high-temperature plasma torch fusion on the input heavy oil residues, and glass body waste slag and synthesis gas containing CO2, CO and H2 are generated through conversion. The sludge splitting decomposition treatment method has the advantage that the harmless treatment degree is high.

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...
