Embodiment 1
[0030] Embodiment one: as attached figure 1 As shown, the suspended micro fume particle separation device on the range hood includes a range hood body 1 and a range hood collecting device 4. The range hood collecting device 4 is located below the range hood body 1 and further includes Oil fume velocity slowing condenser 3, rectification net 6, oil fume water molecule collision mixing condenser 2 and cold water particle generator 5 located on range hood body 1, said oil fume velocity slowing condenser 3, rectification net 6, oil fume water The molecular collision mixing condenser 2 is located above the oil fume collecting device 4 , and the cold water micro particles generated by the cold water micro particle generator 5 are sprayed in the oil fume velocity slowing condenser 3 and / or the oil fume water molecule collision mixing condenser 2 .
Embodiment 2
[0031] Embodiment 2: In the foregoing embodiment, as attached Figure 4 As shown, the oil fume water molecule collision mixing condenser 2 is provided with a channel communicating with the cold water particle generator 5, and the side wall of the oil fume water molecule collision mixing condenser 2 is provided with a plurality of The water molecule collision mixing condenser 2 is a water mist spray nozzle for spraying water mist inside; specifically: a left water mist spray nozzle 22 and a right water mist spray nozzle 21 can be respectively provided on both sides; In the device 2, the atomized water mist is sprayed on the area through a reasonable arrangement of water mist nozzles to form a certain concentration. Atomized water molecules collide and mix thoroughly.
Embodiment 3
[0032] Embodiment three: In the above embodiment, as attached figure 2 As shown, the oil fume flow velocity slowing condenser 3 is an inverted trapezoidal structure, and the cross-sectional area of the oil smoke flow velocity slowing condenser 3 gradually increases according to the flow direction of the flue gas. According to the Venturi effect, the oil fume flow rate through the oil fume flow rate slowing condenser 3 can be effectively slowed down, reaching a speed that can effectively condense water molecules and oil smoke, and the cold water tiny particles sprayed in the oil smoke flow rate slowing condenser 3 are in and tiny During the condensation process of soot particles, the temperature of tiny soot particles can be cooled.
