Example Embodiment

[0019] Such as figure 2 The shown multi-stage sludge treatment system has a dehydration zone, an evaporation zone, and a cracking zone arranged in order of position or time. A storage device for sludge is connected before the dehydration zone; the dehydration zone is equipped with Class I heating components, which can make The temperature of part of the sludge reaches 100-200°C.

[0020] An anti-coking agent is pre-added to the sludge. An evaporation zone is connected after the dehydration zone, and a cracking zone is set after the evaporation zone; the evaporation zone is equipped with Class II heating components, which can make the temperature of most of the sludge reach 200-300℃, and a large amount of light oil in the sludge is released; the cracking zone Equipped with Class III heating components, it can make the temperature of most of the sludge reach 300-400℃ or above. A large amount of heavy oil in the sludge produces a cracking reaction, and the heavy oil becomes small ...

Abstract

The invention provides a multistage treatment system for oil sludge. The multistage treatment system may be matched with an oil sludge storage or conveying area, and comprises a dehydration area, an evaporation area and a cracking area which are sequentially arranged, wherein the dehydration area is provided with a first-stage heating part in a matched mode, so the temperature of the oil sludge isallowed to reach 100-200 DEG C; the evaporation area is provided with a second-stage heating part in a matched mode, so the temperature of the oil sludge is allowed to reach 200-300 DEG C; the cracking area is provided with a third-stage heating part in a matched mode, so the temperature of the oil sludge is allowed to reach 300-400 DEG C or above. According to the method, various components in the oil sludge can be separated separately, resource recycling is achieved, pollution release is basically avoided, and good environmental protection performance is obtained.

Description

Technical field [0001] The invention relates to a treatment technology for oily sludge. Background technique [0002] Oily sludge is formed by mixing crude oil or refined oil into soil or other media. The oil cannot be directly recovered and may cause pollution. It is one of the main pollutants in the petrochemical industry. [0003] Oily sludge is generally a stable suspension emulsion system composed of oil-in-water (o / w), water-in-oil (w / o) and suspended solids. The dehydration effect is poor. The composition and physical properties of the sludge are affected by the sewage water quality, treatment process, The addition of chemicals and other factors have large differences, high difficulty in treatment, large differences in oil content, and some have recycling value, and oily sludge contains PAHs, heavy metals and other harmful substances, which also has radioactive pollution to the environment. [0004] The patent application number 2012101036336 invented a resource treatment met...
