High-temperature steam jetting type oil sand and oil sludge treatment device

Abstract

The invention relates to oil sludge treatment equipment for oil producing regions of oil fields, in particular to a high-temperature steam jetting type oil sand and oil sludge treatment device which comprises a cracking evaporation pot, a fractionating tower, a condenser and an oil and water separating pot, wherein the cracking evaporation pot is a vertical pot body on which a heat exchange sandwich layer is arranged, heat conducting oil communicated with a heating oil furnace is arranged in the sandwich layer, an evaporation disc is arranged at the lower part in the pot, high-temperature steam nozzles connected with an superheated steam boiler are uniformly distributed at the bottom of the evaporation disc, a feeding spray pipe connected with a raw material pump is arranged at the side of the evaporation disc, a rotary scraper is arranged at the upper part of the evaporation disc, an air vent which is connected with the fractionating tower through an air pipeline is arranged at the top of the pot, and a spiral slag discharging device is arranged at the bottom of the pot. The high-temperature steam jetting type oil sand and oil sludge treatment device enables oil sludge and high-temperature steam to fully contact and collide with each other and has large treatment capacity; the cracking evaporation pot provides an auxiliary heating function for raw materials to be beneficial for the materials to effectively absorb heat to evaporate oil water; and the cracking evaporation pot is heated by circulating heat conducting oil so that the high-temperature steam jetting type oil sand and oil sludge treatment device has safety and is easy to control.

Description

[0001] technical field [0002] The invention relates to equipment for treating sewage sludge in an oil production area of ​​an oil field, in particular to a high-temperature steam injection type oil sand oil sludge treatment device. Background technique [0003] At present, the treatment methods of oil sludge reported in the literature include biological treatment, freezing and thawing treatment, solvent extraction treatment, coking treatment, etc., which generally have high energy consumption, high treatment cost, secondary environmental pollution, long time, and occupied area. Large, low recycling rate and other problems, the requirements for the composition of the sludge are too high, especially when there are too many impurities and the sludge is solidified and agglomerated, it is basically difficult for the separation device to complete the evaporation of oil and water. Contents of the invention [0004] The present invention aims to solve the above-mentioned problem...
