Description

Technical Field

[0001] The utility model relates to the technical field of heavy fuel oil stability detection, in particular to a heavy fuel oil stability detection sampling device. Background Art

[0002] Heavy fuel oil refers to a brown viscous flammable liquid obtained by reducing the viscosity of the residual oil obtained by regular vacuum distillation of crude oil or by appropriately adding other distillate oils. It is often used as boiler fuel and marine fuel. Generally speaking, in the process of crude oil processing, the lighter components are always separated first. Fuel oil, as a kind of finished oil, is a heavier residual product separated from crude oil after gasoline, kerosene and diesel in the process of oil processing. Fuel oil is widely used as fuel for ship diesel engines, heating furnaces, metallurgical furnaces and other industrial furnaces. Fuel oil is mainly made of cracked residual oil and straight run residual oil of petroleum. It is characterized by high viscosity and contains a lot of non-hydrocarbon compounds, colloids and asphaltene. As the last product in the refining process, fuel oil has a strong particularity in product quality control. The final formation of fuel oil products is restricted by many factors such as crude oil variety, processing technology, and processing depth.

[0003] In the disclosed patent (CN212988921U, a heavy fuel oil stability detection sampling device), heavy fuel oil with fewer impurities above the horizontal plane of the liquid outlet pipe is discharged from the liquid outlet pipe to obtain heavy fuel oil with fewer impurities, thereby detecting the obtained heavy fuel oil, which is convenient for detecting the heavy fuel oil and the data obtained by the detection is more reliable; the heavy fuel oil can be quickly extracted and multiple groups of samples can be quickly obtained, the operation is simple, the sampling efficiency is high, and the detection speed is improved. Although heavy fuel oil with fewer impurities can be obtained, the circular groove on the turntable has a fixed aperture and can only hold test tubes of a single diameter, and test tubes of different diameters cannot be placed. When the test tube receives the fuel oil released from the liquid outlet pipe, it is easy to cause the fuel oil to splash and cause pollution. Therefore, we have introduced a new heavy fuel oil stability detection sampling device. Utility Model Content
