High efficiency oil sludge resource utilization system

Abstract

The invention discloses a high efficiency oil sludge resource utilization system. The high efficiency oil sludge resource utilization system is used in the field of oil sludge pyrolysis resource utilization, is capable of solving technical problems in the prior art that in pyrolysis of oil sludge, preferable evaporation of crude oil in oil sludge is impossible to realize, pyrolysis efficiency is not high, and crude oil recovery rate in oil sludge is relatively low. The high efficiency oil sludge resource utilization system comprises a pyrolysis system used for pyrolysis of the oil sludge, a heat supply system used for providing the pyrolysis system with heat, an explosion-proof system used for preventing crude oil combustion or explosion, and a condensation system; a crushing assembly comprises a driving shaft and a driven shaft which are connected with a housing in rotation connection, first blades arranged on the driving shaft, and second blades arranged on the driven shaft. The technical effects are that: in rotation of the driving shaft and the driven shaft, the first blades and the second blades are arranged in a staggered manner, so that repeat cutting crushing on oil sludgeis realized, full evaporation of crude oil in oil sludge is realized, and pyrolysis efficiency and crude oil recovery rate are increased preferably.

Description

technical field [0001] The invention relates to the field of oil sludge pyrolysis resource utilization, in particular to an efficient oil sludge resource utilization system. Background technique [0002] In the process of mining, transporting and processing petroleum in the petrochemical industry, a large amount of sludge will be produced. According to data, the annual output of oil sludge produced in the process of oil exploitation in my country has exceeded one million tons. These sludges are difficult to settle and contain a large amount of metal pollutants. If they are discharged directly, they will pollute land and water resources. With the overall improvement of my country's environmental protection awareness and the improvement of my country's environmental protection laws and regulations, the treatment technology of oil sludge has become a hot issue in the field of energy and environmental science. [0003] At present, the treatment technologies of oily sludge at h...

Problems solved by technology

[0005] Although this sludge pyrolysis treatment system can extract the crude oil in the sludge, when the sludge is pyrolyzed in the gas-solid separation cylinder, the crude oil inside the sludge cannot be evaporated well, the pyrolysis efficiency is not high, and the oil in the sludge The recovery rate of crude oil is also low
