Abstract

The present invention relates to the technical field of iron-containing oil sludge treatment, in particular to a treatment device and method for iron-containing oil sludge, comprising a distributing plate moving along a set direction and a closed shell surrounding the surrounding and top of the distributing plate; the shell includes The drying section, the dry distillation section and the cooling section are arranged in sequence along the moving direction of the distribution plate; the starting end of the drying section on the shell is provided with a feed port, and the end of the cooling section is provided with a discharge port; the drying section and the dry distillation section are respectively equipped with A plurality of radiation heating tubes arranged at intervals; the radiation heating tubes are fixed on the side wall of the shell; an indirect cooling heat exchanger is arranged in the cooling section, and the two ends of the indirect cooling heat exchanger are respectively fixed on the side wall of the shell; The shell is provided with an oil and gas outlet. The iron-containing oil sludge processing device provided by the invention improves the heat utilization rate and the oil yield rate.

Description

technical field [0001] The invention relates to the technical field of iron-containing oil sludge treatment, in particular to an iron-containing oil sludge treatment device and a treatment method. Background technique [0002] Iron and iron oxide account for 70% to 80% of iron-containing sludge, and the rest is emulsion and water. A cold-rolled strip steel plant with an annual output of 1 million tons produces 3,000-4,000 tons of iron-containing sludge a year. Usually a large amount of iron-containing sludge is treated as solid waste, which not only costs sludge treatment fees, but also wastes iron resources and causes secondary pollution to the environment. [0003] The related treatment of iron-containing sludge can recover iron and the oil in the emulsion. The commonly used method for treating iron-containing sludge is incineration. The iron-containing sludge is incinerated, and the high-temperature flue gas generated by incineration is used to dry and oxidize ferric oxid...
