In the two-stage flotation of the flotation deinking equipment unit, the purpose of the first stage flotation is to improve the cleanliness and whiteness of the slurry, and the second stage of flotation selection does not affect the whiteness and cleanliness. Increase the yield of the slurry to avoid the loss of slurry. In the removal of ash, the second-stage flotation plays a key role, with high selectivity, so that the deinking equipment unit can reduce the loss of fine fibers while removing ash. The foam removed by the deinking unit has approximately 66%-74% ash and 26%-34% fine fibers. Among the 8% of the total loss of slurry flotation, the amount of gray powder removed was 5.6%, the amount of ink removed was 1.5%, and the loss of fiber and fine fiber accounted for only 0.9% of the total loss of flotation.

The flotation deinking equipment unit can be composed of several flotation deinking tanks, liquid level adjustment and shipping, and bubble generation ejector. Users can carry out serial number according to the variety of waste paper raw materials and the flotation quality requirements of flotation deinking pulp. s Choice. The deinking equipment unit is formed by two stages of flotation deinking (four or more flotation deinking tanks) and two liquid level adjusting devices in series.
