Description

Technical Field

[0001] The present application relates to the field of mechanical engineering technology, and in particular to a multi-layer and multi-point oil-in-water detection device. Background Art

[0002] Water is a precious resource essential for human survival. Oil in water is a common type of water pollution, with immeasurable impacts on organisms and the environment. Therefore, oil content testing in water is essential in fields such as sewage treatment, the petroleum industry, aquaculture, and marine science.

[0003] Currently, common methods for oil-in-water detection include gravimetric analysis, ultraviolet spectrophotometry, infrared absorption, and ultraviolet fluorescence. These methods take a long time to measure oil content in water and have low sensitivity. Ultraviolet fluorescence, on the other hand, offers advantages such as high sensitivity, short detection time, rapid detection speed, environmental friendliness, and high efficiency. Compared to other methods, it can provide qualitative and quantitative analysis of oil in water. Therefore, commercially available oil-in-water sensors often use the ultraviolet fluorescence method.

[0004] Oil-in-water sensors using ultraviolet fluorescence are suitable for a variety of water environments and can detect oil content in water in real time. However, the detection range of a single oil-in-water sensor is limited, meaning it can only detect the oil content at a specific point within a specific area. When responding to an oil spill in a large area, the data from a single oil-in-water sensor cannot accurately reflect the oil's distribution within the water, as oil quickly spreads due to surges.

[0005] Therefore, how to improve the detection range of oil in water detection devices and improve the accuracy of device detection data has become a technical problem that needs to be solved urgently. Utility Model Content
