背景技术Background technique
油田在生产过程中,原油开采、储存、集输、加工以及原油采出液处理过程中都会产生的污泥。污泥主要分为:落地油泥、清罐油泥、浮选浮渣等。含油污泥堆放或填埋占用大量耕地的同时污染周边环境,所产生的有毒物质会随动植物吸收富集、食物链传递而最终危害人类健康。同时,污油泥中含油量较高,是废物中的宝贵资源,如果不进行回收,会造成较大的资源浪费。目前,按照国家环保要求,油田污油泥处理后残渣必须达到石油烃总量≤0.3%,灰渣浸出液检测无有毒有害物质及重金属,符合《农用污泥中污染物控制标准》(GB4284-1984)中有关规定;单一的采用如热化学处理、溶剂处理、离心法处理工艺已不能达到其标准要求。During the production of oil fields, sludge will be produced during crude oil extraction, storage, gathering and transportation, and processing of crude oil production fluids. Sludge is mainly divided into: floor sludge, tank clear sludge, flotation scum and so on. The storage or landfilling of oily sludge occupies a large amount of arable land and pollutes the surrounding environment. The toxic substances produced will be absorbed and enriched by animals and plants, and passed through the food chain, and eventually endanger human health. At the same time, sludge sludge has a high oil content and is a valuable resource in waste. If it is not recycled, it will cause a large waste of resources. At present, according to national environmental protection requirements, the residue of oilfield sludge sludge treatment must reach the total amount of petroleum hydrocarbons ≤ 0.3%, and the ash and slag leachate is tested to be free of toxic and harmful substances and heavy metals. Relevant regulations in China; single-use processes such as thermochemical treatment, solvent treatment, and centrifugation can no longer meet its standard requirements.

Pyrolysis can effectively convert the organic matter in the material into a usable form. At present, there are plans to use natural gas heating and pyrolysis technology to treat sludge sludge, but there are unreasonable distribution of heating furnace body, low thermal efficiency, complicated equipment, difficult pyrolysis control, large volume, high operating cost and small processing scale. It is not easy to transport and install. The residue after sludge sludge treatment cannot meet the requirements of total petroleum hydrocarbons ≤ 0.3%, and there are disadvantages such as secondary pollution. Therefore, there is an urgent need for a harmless intelligent sewage sludge pyrolysis treatment device and treatment method that can monitor and adjust in real time to improve the current defects.
