In restaurant kitchens, food processing workshops, and other industrial environments, fume is not only a major source of air quality pollution but also a hidden threat, threatening equipment safety, harming human health, and triggering environmental complaints. Traditional fume exhaust systems often rely solely on fans to expel fumes directly into the atmosphere, which not only pollutes the environment but also easily causes oil accumulation in pipes, fire hazards, and oil dripping from exterior walls. The emergence of modern fume-purifying fume separators has revolutionized this situation. They not only efficiently purify fume, but also achieve visible fume separation through advanced physical separation technology. During operation, you can clearly see thick smoke entering and clean air exiting, with oil droplets intercepted and converged into streams, making the purification effect truly visible and tangible.1. Multi-stage separation structure: Fumes are filtered layer by layer, leaving no oil mist behind.The key to the visible separation effect of fume-purifying fume separators lies in their scientifically designed multi-stage separation system. The process typically involves four stages: primary filtration, centrifugal separation, electrostatic adsorption, and final purification. Each stage precisely intercepts oil mist particles of varying sizes. When flue gas containing high-temperature oil mist enters the equipment, it first passes through a wire mesh primary filtration layer. Large oil droplets are intercepted and condensed into droplets, which then flow down the mesh into the oil collection tank. This process allows for visible oil stains adhering to the filter, providing the first visual evidence of "visible purification." The flue gas then enters the centrifugal separation zone. A high-speed rotating mechanical device or spiral guide structure uses centrifugal force to eject oil mist particles from the airstream. These particles impact the walls of the filter, forming an oil film that flows along the inner wall into the oil tank at the bottom. Through the transparent window or observation port, the oil droplets can be clearly seen falling like raindrops, while the flue gas gradually becomes thinner and more transparent, creating a striking visual contrast.2. Electrostatic Adsorption Technology: Making Micron-Level Oil Mist "Embracing"Although primary separation and centrifugal separation remove most oil smoke, a large number of submicron-sized particles remain suspended in the air. While imperceptible to the naked eye, they are a major source of PM2.5. To address this issue, high-end fume separators are equipped with a high-voltage electrostatic adsorption module. When the flue gas passes through an electric field, the oil mist particles are ionized and charged. They are then attracted to the oppositely charged dust collecting plates, forming an oil film that automatically drips off. While this process occurs internally, many devices feature a transparent electric field observation window or LED indicator. During operation, the electric field glow can be seen. After shutdown, the oil film covering the dust collecting plates can be seen, providing a visual display of the purification results. This contrast of "visible oil droplets at the front and cleanliness at the back" is a powerful demonstration of "visible" purification.3. Visual Design: Making the Results "Visible and Trustworthy"To allow users to more intuitively experience the purification results, modern fume separators generally adopt a visual design concept. For example:Transparent observation windows: Located in the primary filter layer, centrifugal zone, and air outlet, they facilitate real-time monitoring of oil interception and air cleanliness.Transparent scale design for the oil sump: Allows direct visualization of collected waste oil volume, quantifying purification results.Before-after comparison duct design: Some high-end models feature dual-channel displays, one for untreated flue gas and the other for purified air, creating a sharp contrast.These features not only enhance the device's technological appeal but also strengthen user confidence in its purification effectiveness. They are particularly suitable for restaurants demonstrating their environmental commitment to customers or providing visual evidence for businesses responding to environmental inspections.The fume separator utilizes multi-stage physical separation technology and a visually readable structure to make the previously invisible fume treatment process clearly visible. From oil droplets falling off, flue gas clearing, to waste oil collection, each step of the purification process is intuitively displayed, allowing users to see the results with their own eyes, rather than relying on feelings. This "visible purification" is not only a reflection of technological advancement but also a strong commitment to environmental responsibility.
