Description

Technical Field

[0001] The utility model relates to the technical field of oil storage, in particular to a stratified monitoring device for an oil adjustment storage tank. Background Art

[0002] Fuel oil usually refers to the heavy residual oil separated during the petroleum refining process. It is widely used as fuel for ships, industrial heating and power stations. Fuel oil is a dark brown viscous flammable liquid with moderate viscosity and high calorific value. It is suitable for use as a high-efficiency fuel. Its specific gravity is generally between 0.82 and 0.95, and it has a high energy density, which makes it very economical in industrial applications. Fuel oil usually needs to be blended before it is put into use. Oil blending, or oil blending, is a process of improving and customizing the properties of oil products, aiming to make the fuel oil meet specific performance requirements to adapt to different usage conditions and environmental standards.

[0003] By blending the oil, the chemical composition and physical properties of the fuel oil can be optimized, such as reducing the viscosity and adjusting the flash point, thereby improving the combustion efficiency and safety. The oil blending can also reduce the content of impurities in the fuel oil, such as sulfur and nitrogen. These impurities will produce pollutants when burned, affecting the environmental quality and equipment life. However, in the existing fuel oil blending and storage process, after a long storage time, the blended oil will show stratification, which seriously affects the performance of the oil. In order to monitor the stratification phenomenon of the oil and solve the problem in time, a stratification monitoring device for an oil blending storage tank is proposed to solve the above problem. Utility Model Content
