Device for evaluating scaling corrosion of raw oil to oil refining hydrogenating equipment

The utility model discloses a device for evaluating scaling corrosion of raw oil to oil refining hydrogenating equipment. The device comprises a high-pressure kettle made of a corrosion-resistant material, a kettle cover hermetically connected with the high-pressure kettle, a pressurizing mechanism, a heating part, a temperature controlling part and a test piece frame, wherein the heating part is controlled by the temperature controlling part, the bottom of the high-pressure kettle is of an inverted cone shape, and is supported by a base, an emptying valve is arranged at the bottom of the high-pressure kettle and used for emptying a raw material in the high-pressure kettle; at least one interface is formed in the kettle cover, and used for connecting an accessory required by a test. The device can be used for simulating a reaction condition in the oil refining hydrogenating equipment so that the scaling corrosion rate of a raw material is tested and an actual production operation is guided.
