Problems solved by technology

[0004] The technical problem to be solved by the present invention is that a large amount of oily sludge is inevitably produced in the oil field during production and construction, mainly including landed sludge, settling tank sludge, three-phase separator sludge, and oil spill sludge. Oily sludge is required to be treated, the current treatment of oily sludge is very difficult, and it is easy to cause secondary pollution. Aiming at the above problems, a harmless oily sludge treatment device and method are proposed

Abstract

The invention relates to an oil-containing-sludge harmless treatment device and method. According to the oil-containing-sludge harmless treatment device, under the anaerobic state and heating of a hot-air system, temperature environments of 200 DEG C to 500 DEG C can be regionally formed, most of oil in oil-containing sludge can be pyrolyzed and recycled, a part of organic matter is subjected to apyrolytic reaction, and flammable non-condensable gas is generated, is led out and combusted in a combustion system capable of independently supplying wind, and serves as a second heat source for supplementing heat, so that the pyrolytic reaction is kept continuous; the whole reaction process is safe and high in controllability; hot wind and air are not in direct contact with the oil-containing sludge, an oxidation reaction is not generated, contaminants such as raise dust and Dioxin are not generated, and good environment-friendly ecological benefits are achieved; the oil in the oil-containing sludge can be fully recycled through the whole pyrolytic reaction, generated pyrolysis gas can supplement heat energy consumption, and economic benefits are good; the treated products are inorganiccarbon particles, contaminants such as heavy metal are subjected to complexing in a carbon structure, environmentally-friendly landfill and reusing can be achieved, and the thorough decrement harmless aim is achieved.

Description

【Technical Field】 [0001] The present invention relates to equipment and method for treating oily sludge, in particular to a device and method for harmless treatment of oily sludge. 【Background technique】 [0002] With the development of society, mankind has a great demand for oil. During the production and construction of oil fields, a large amount of oily sludge is inevitably produced, mainly including floor sludge, sedimentation tank sludge, three-phase separator sludge and oil spilled sludge. With the increasing environmental protection requirements, the treatment of oily sludge has become a hot and difficult point. If it is not handled properly, it will cause secondary pollution. [0003] Therefore, there is a need for a harmless treatment device and method for oily sludge, which can analyze and recover most of the oil in the oily sludge, and part of the organic matter undergoes pyrolysis reaction to produce combustible non-condensable gas, which is led to the independent air s...
