The invention discloses an
oil mist filter which comprises an
exhaust pipe, a purifying mechanism, a separating mechanism, a collecting tank, a supporting foot stand, an air inlet mechanism and a discharging
pipe; the purifying mechanism is mounted at the upper end of the separating mechanism, and the
exhaust pipe is mounted at the position, close to the middle, of the upper end of the purifying mechanism. According to the invention, an exhaust fan and an air suction fan are arranged, so that the separation and purification efficiency of
mixed gas is improved, the separation and purification time is shortened, and the exhaust fan and the air suction fan can be matched with other components in the invention at lower power to complete better exhaust purification effect compared with a largeexhaust fan; the
power consumption of a factory is reduced, and the energy-saving effect is achieved; gas is introduced into water through a U-shaped
pipe and a hose, part of the gas dissolved in water can be dissolved, the other part of the gas insoluble in water can enter a purification bin, peculiar smells and harmful gas in the gas are removed through
activated carbon, the gas purification effect is improved, and great significance is achieved for
environmental protection of the
ecological environment.
