Description

Technical Field

[0001] The utility model belongs to the technical field of oil-liquid separation, and in particular relates to an oil-liquid separation device. Background Art

[0002] An oil-liquid separator is a device specially used to separate oil and water and is widely used in catering and industrial fields.

[0003] Oil-liquid separators can be divided into two types according to different application scenarios: catering oil-liquid separators and industrial oil-liquid separators: catering oil-liquid separators: mainly used in the catering industry to treat oily wastewater generated in the kitchen. Due to the requirements of environmental protection regulations, these wastewaters need to be purified before discharge. Industrial oil-liquid separators: used in various industrial occasions, such as air compressors, ships, cars, etc., to treat industrial wastewater or waste oil containing grease. When scrapped cars are dismantled, a large amount of oily wastewater with impurities will be generated. This wastewater must be treated very strictly before it can be discharged to protect the environment from pollution. The working principle of the oil-water separator is mainly based on the differences in the physical properties of oil and water, such as density, centrifugal force, and electrostatic force. Specifically, oil is usually lighter than water, so the difference in gravity can be used to make the oil float to the water surface for separation. Different treatment methods and techniques may be required for oil in different states (free, dispersed, emulsified, dissolved, and attached oil on solids).

[0004] In summary, oil-liquid separators play an important role in environmental protection and resource recovery. They can reduce environmental pollution by effectively separating oil and water, while also recovering valuable oils and fats to achieve sustainable development.

[0005] In the existing oil-liquid separator for dismantling scrapped cars, if the feed speed changes during oil-liquid separation, especially when the speed is too fast or too slow, it may affect the separation effect of oil droplets, resulting in reduced oil droplet separation efficiency. The change in speed when the oil enters the storage area from the separation area will also affect the oil-liquid separation effect and the stability of the tank. Moreover, during oil-liquid separation, the oil solidifies due to the decrease in temperature, the impurity sedimentation efficiency is low, and excessive impurities can easily cause damage to the oleophobic material.
