Be taper bottom described staving, staving 2 least significant end is provided with slag notch, is provided with evacuation port in the middle of clarifying chamber 7 tapered sidewalls.
Be taper bottom described gas-floating chamber, in the middle of the tapered sidewalls of side, clarifying chamber 7, be provided with overflow port.
Described gas-floating chamber other side side wall upper part is provided with oil discharge outlet, and the bottom of oil discharge outlet is than the bottom height 1-3cm of oil outlet.
Described gas-floating chamber bottom is provided with air supporting producer, centrum is provided with baffle plate topmost, uniform through hole on described baffle plate 16, every square decimeter is provided with through hole 50-100, the diameter of the through hole of described through hole is 1-5mm, the top of described baffle plate is provided with discharge port, and bottom described discharge port outlet and bottom oil discharge outlet and overflow port top is in same level.
Distance between described discharge port and baffle plate accounts for the 1/10-1/20 of staving height.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows:
(1) due to bubble and solution counter current contact, the oil content that the minimum and solution of bottommost of the oil droplet of the bubble adhesion of bottommost contains is minimum, thus the solution oil content content that bottom is discharged reduces greatly, and oil removal efficiency improves greatly.
(2) adopt interlayer design, decrease occupation area of equipment, and decrease the backlog of solution.
