Problems solved by technology

At present, the types of domestic incinerators mainly include: mechanical grate furnace, fluidized bed, rotary kiln and other furnace types. Each has its own advantages in the technical field, but it has not been able to effectively save energy, reduce consumption and reduce emissions to achieve a circular economy.

Embodiment Construction

[0011] Petroleum sludge pretreatment system. Contains three parts: recovered petroleum sludge, petroleum sludge dehydration treatment and petroleum sludge mixing. Petroleum sludge is generally divided into three categories: slurry liquid, semi-solid and solid petroleum sludge. The slurry-liquid petroleum sludge is coarsely filtered with grids to demulsify, reduce viscosity, filter pressure and dehydrate once, mix with semi-solid petroleum sludge once, heat and air dry for secondary dehydration, and then mix with solid petroleum sludge for a second time Then sent to the spare silo in the incineration system for incineration treatment

[0012] Pyrolysis and incineration. The pyrolysis incineration system adopts an inverted "U" type incinerator. The petroleum sludge is continuously fed into the furnace body through a multi-roll evacuation feeding device and a rotating distribution system. The distribution system can spread the materials evenly and ensure that the materials are in the...

Abstract

The invention discloses a technological device system which aims at harmless treatment and resource energizing utilization of petroleum mud residue waste produced in process of petroleum production and refining. The system components comprise a petroleum mud residue pretreatment system, a pyrolytic incineration system, an exhaust treatment system, an energizing utilization system, and an automatic monitoring system. A technological process that petroleum mud residue pretreatment->pyrolytic incineration->energizing utilization->exhaust acid and dust removal->discharge while reaching environmental protection standard. Oilfield wet vapor of subcritical super high pressure produced by energizing treatment after the pyrolytic incineration of the petroleum mud residue is applied to steam injection in oilfield and oil well. The petroleum mud after efficient utilization no longer contains petroleum or other harmful components, thus meeting environmental protection requirements and realizing aim of minimizing, harmless treatment and resource utilization of dangerous waste treatment.

Description

Technical field [0001] The invention is a process device system for generating subcritical ultra-high pressure wet steam by performing harmless energy accumulation treatment and resource utilization of petroleum sludge generated in the process of petroleum production and refining. Background technique [0002] Petroleum sludge refers to the hazardous waste formed after mud sand or other substances are polluted by petroleum, which mainly comes from the mud and sand precipitation carried by crude oil in the process of petroleum exploration and refining, the scum and bottom mud of oil production sewage, as well as drilling and oil extraction. And pollutants formed by the mixing of ground crude oil, soil, and debris generated in the process of gathering, transportation, storage and transportation. After petroleum sludge is discharged into the environment, it pollutes the environment and is listed as hazardous waste in the "National Hazardous Waste List". The petroleum sludge containi...
