Description

technical field

[0001] The invention relates to the technical field of environment, energy and environmental protection, in particular to a continuous feeding device for oil sludge pyrolysis. Background technique

[0002] The annual output of oily sludge in my country is huge, and there are three main ways of generation: during the extraction of crude oil, during the production and transportation of crude oil, and in the sewage treatment plant of the refinery. Among them, in the process of crude oil extraction, the oil sludge output is 0.5% to 1% of the crude oil output. According to the figures from the National Bureau of Statistics, the total crude oil extraction in my country in 2014 was 2.1×10 8 tons, and the output of oil sludge is about 2 million tons, and many oil fields in my country have entered the end stage of exploitation, and the proportion of oil sludge production will be even greater. The oil content of oily sludge is generally between 20% and 50%, and the wa...
