Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.
[0014] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.
[0015] Example 1
[0016] See also Figure 1 and Figure 2 As shown, an oil mist recovery device involved in this embodiment includes an oil mist recovery shell 100 having a front shell plate 1 and a rear shell plate 2, the front shell plate 1 is provided with a rectangular oil mist inlet hole 3, an upper guide groove 4 arranged inside the oil mist recovery shell 100 is provided above the oil mist inlet hole 3, and a lower guide groove 5 arranged inside the oil mist recovery shell 100 is provided below the oil mist inlet hole 3, a foam metal plate 6 for shielding the oil mist inlet hole 3 is provided inside the oil mist recovery shell 100, the foam metal plate 6 is made of foam copper or foam nickel material, the upper end of the foam metal plate 6 is slidably connected in the upper guide groove 4, and the lower end is slidably connected in the lower guide groove 5, an oil collection groove 7 communicating with the lower guide groove 5 is provided below the lower guide groove 5, a supporting mesh plate 8 is provided between the oil collection groove 7 and the lower guide groove 5, the lower end of the foam metal plate 6 is pressed on the supporting mesh plate 8, and a negative pressure pipe 10 and an exhaust fan 11 for providing negative pressure to the negative pressure pipe 10 are connected to the oil mist recovery shell 100.
[0017] Furthermore, the negative pressure pipe 10 is connected to the rear shell plate 2 .
[0018] In this embodiment, by turning on the exhaust fan 11, negative pressure is formed inside the negative pressure pipe 10 and the oil mist recovery shell 100 connected thereto, so that the foam metal plate 6 has suction facing the oil mist surface, and the external flue gas is sucked into the oil mist recovery shell 100. During this period, the flue gas passes through the irregular mesh holes on the foam metal plate 6, and while being filtered, the flue gas is also cooled, causing the high-temperature oil mist to be liquefied, forming oil droplets that flow downward with gravity, pass through the supporting mesh plate 8, and are collected in the oil collection tank 7.
