Description of reference numerals: the device comprises a box body 1, a cylinder 2, a water inlet hole 3, a first water pipe 4, a water outlet pipe 5, a wing plate 6, honeycomb inclined pipe packing 7, an oil collecting hole 8 and an oil sludge discharging hole 9.
Detailed Description
Embodiments of the present invention will be described in detail below with reference to examples, but those skilled in the art will appreciate that the following examples are only illustrative of the present invention and should not be construed as limiting the scope of the present invention.
An oil separation sedimentation tank comprises a tank body 1, wherein the tank body 1 comprises side plates and a bottom plate; the inner surface of the bottom plate is provided with a cylinder 2, the bottom of the cylinder 2 is provided with a water inlet hole 3 tangent to the inner surface of the cylinder 2, the bottom plate is provided with a first through hole outside the cylinder 2, and a water inlet pipe is connected between the water inlet hole 3 and the first through hole; a plurality of second through holes are uniformly formed in the lower part of the cylinder 2, and one end, on the inner surface of the cylinder 2, of each second through hole is connected with a first water pipe 4; the water outlet pipe 5 is coaxial with the cylinder 2, and the other ends of the first water pipes 4 are connected with the lower part of the water outlet pipe 5;
the outer surface of the upper end of the cylinder 2 is provided with a wing plate 6; a honeycomb inclined tube filler 7 with a horizontal included angle of 45-60 degrees is arranged between the middle part of the outer surface of the cylinder 2 and the side plate;
an oil collecting hole 8 is formed in the upper portion of the side plate, and the height of the oil collecting hole 8 is lower than that of the cylinder 2; and the bottom of the side plate is provided with an oil sludge outlet 9.
Furthermore, one end of the water inlet hole 3 on the inner surface of the cylinder 2 is connected with a water inlet guide pipe, the other end of the water inlet guide pipe is tangent to the inner surface of the cylinder 2, and the water inlet guide pipe is inclined upwards by 30-60 degrees.
Further, the water inlet guide pipe is inclined upward by 45 °.
Oily wastewater finally enters the cylinder 2 along the tangential direction of the inner wall of the cylinder 2 after passing through the first through hole, the water inlet pipe, the water inlet hole 9 and the water inlet guide pipe at a certain speed, the speed of the wastewater entering the cylinder 2 is related to the upward inclination angle of the water inlet guide pipe, the height of the cylinder 2 and the radius of the cylinder 2, so that the wastewater generates rotational flow reaction in the cylinder 2, and oil drops in the wastewater collide and are coalesced into oil drops with larger particle size. The waste water flows out from the upper end of the cylinder 2 and enters the box body 1.
The oil drops with larger particle sizes in the wastewater firstly float upwards under the action of the relative density difference of oil and water, and the oil drops with smaller particle sizes flow downwards along with water flow; when the oily wastewater passes through the honeycomb inclined tube filler 7, small oil drops touch the plate surface to be gathered and move upwards to an inclined tube outlet, namely large oil drops are formed and float to the water surface; because the equivalent diameter of the pipeline is smaller, the pipeline can still keep a laminar flow state under higher treatment capacity and has a large buoyancy area, and therefore, the efficiency of removing the small-particle floating oil is higher. The oil content of the wastewater passing through the honeycomb inclined tube filler 7 is reduced, and the wastewater is pumped out through the first water pipe 4 and the water outlet pipe 5 by the sewage pump and discharged out of the oil separation sedimentation tank.
The oil layer on the water surface of the wastewater is discharged into the sump oil tank through the oil collecting hole 8, and the oil sludge is deposited at the bottom of the tank. The sludge outlet opening 9 is normally closed and is opened when sludge treatment is required.
Although the invention has been described in detail in this specification with reference to specific embodiments and illustrative embodiments, it will be apparent to those skilled in the art that certain changes and modifications can be made therein without departing from the scope of the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
