The oil-containing sludge treatment system comprises a pretreatment system, an oil-sludge separation system, a sludge-sand separation system, a sludge-water separation system, a film curing system, a full-circulation dry distillation system, a heating system, a clean water system, a sewage tank and an oil storage tank, wherein the pretreatment system comprises a crushing machine, a screening device, a collecting tank and a waste pond, is used for crushing, screening and fluidizing an oil-containing sludge raw material and used for collecting wastes, and is respectively connected with the heating system and the oil-sludge separation system; the oil-sludge separation system is respectively connected with the heating system, the sludge-sand separation system and the oil storage tank; the sludge-sand separation system is connected with the sludge-water separation system; the sludge-water separation system isused for separating sludge from water and respectively connected with the film curing system and the sewage tank; the film curing system is connected with the full-circulation dry distillation system;the full-circulation dry distillation system is respectively connected with the sewage tank and the oil storage tank; the clean water system is respectively connected with the sludge-sand separationsystem and the sludge-water separation system.

Description

technical field [0001] The invention relates to the technical field of oily sludge treatment, in particular to an oily sludge treatment system and process. Background technique [0002] At present, a large amount of oily sludge is produced in my country every year. According to the "National Hazardous Waste List", oily sludge is classified as HW08 hazardous waste. In actual production, four treatment methods are mainly used in China: (1) cracking method, with less processing capacity, high energy consumption, high cost, and high risk. Dioxin, carbon dioxide and other gases will be produced during production, and there is a risk of deflagration And other hidden dangers, heavy secondary pollution. (2) The incineration method has high energy consumption, high cost, and high risk. A large amount of harmful gases are produced during the incineration process, and secondary pollution is serious. (3) The traditional hot water washing method occupies a large area, and the treated s...
