Detailed Description

The utility model is further illustrated below:

by figure 1, an oily sewage whirl filter equipment, including body 11, body 11 is inside to divide into about through baffle 15 not communicating two cavitys, is equipped with whirl chamber 3 and secondary treatment room 13 in the cavity of left side, and wherein whirl chamber 3 is big-end-up's toper, and one side of whirl chamber 3 is connected with one-level inlet tube 2, and 2 water inlet directions of one-level inlet tube are the tangential direction of whirl chamber 3, and one-level play oil pipe 4 is connected at 3 tops of whirl chamber, and whirl chamber 3 connects secondary treatment room 13 through the one-level outlet pipe 1 of bottom. The secondary treatment chamber 13 is internally provided with an oil removing filler 5, the oil removing filler 5 is a mixture of a hydrophilic oleophobic module and an oleophilic hydrophobic module, can coalesce tiny and free oil in water, and has good effect on oil drops with the particle size of less than 10 mu m. The hydrophilic oleophobic adsorption particles comprise an outer skin and at least one inner core wrapped by the outer skin, wherein the outer skin is a hydrophilic oleophobic layer, the hydrophilic oleophobic layer is synthesized by bonding reaction of hydrophilic groups and polar groups contained in fluorocarbon active agents, the outer skin is of a double-layer structure, the outer layer is of a membrane structure, and the inner layer is of a porous structure; the inner core is made of water-absorbing materials. The crust can separate oil and permeate water, and the water that gets into the inside of adsorption particle passes through the inner core and adsorbs. The oleophylic and hydrophobic adsorption particles comprise fiber structures and nanoscale carbon particles, wherein the fiber structures are mutually interwoven to form a loose base material, and the nanoscale carbon particles are distributed in the base material. The material has a contact angle to water of more than 150 degrees and a contact angle to oil of less than 10 degrees, and has good oleophylic and hydrophobic properties. The hydrophilic oleophobic adsorption particles and the oleophilic hydrophobic adsorption particles are mixed to form the oil removing filler, and the original characteristics of the two particles are kept after mixing, so that new substances cannot be formed. The filler cover plate is arranged above the oil removing filler 5, so that the filler can be fixed, and the phenomenon of material running of the filler under the conditions of large flow and large pressure is prevented.

The top of the second-stage treatment chamber 13 is provided with a second-stage oil collecting cavity 6, the second-stage oil collecting cavity 6 is connected with a second-stage oil outlet pipe 7, the second-stage treatment chamber 13 is connected with a diffusion cavity 8 through a second-stage water outlet pipe 14, and an inlet of the second-stage water outlet pipe 14 is positioned at the bottom of the oil removing filler 5. The diffusion cavity 8 is located the body right side cavity, and diffusion cavity 8 top is equipped with tertiary oil collecting cavity 9, connects tertiary oil outlet pipe 10 on the tertiary oil collecting cavity 9. The diffusion cavity 8 is of an open type bell mouth structure and is communicated with the inner cavity of the body 11, when sewage enters the diffusion cavity 8, the flow area is suddenly increased, the pressure is instantly reduced, and fine oil drops in the sewage float to the upper three-stage oil collecting cavity 9 and are finally discharged from the three-stage oil outlet 10. The bottom of the right cavity of the body 11 is connected with a drainage pipe 12.

When oily sewage enters the swirl chamber 3 from the primary water inlet pipe 2 along the tangential direction of the swirl chamber 3, the oily sewage is centrifugally separated at a high speed in the oily sewage, oil drops with small specific gravity float upwards and are discharged from the primary oil outlet pipe 4, water has larger specific gravity than oil, so the water flows into the secondary treatment chamber 13 from the primary water outlet pipe 1 at the bottom of the swirl chamber 3, and the oil removing filler 5 in the secondary treatment chamber 13 can coalesce tiny and free oil in the water, so the oily sewage has a good effect on the oil drops with the particle size of less than 10 mu m. The sewage passing through the secondary treatment chamber 13 enters the diffusion chamber 8, fine oil drops in the sewage float to the upper tertiary oil collecting chamber 9 and are finally discharged from the tertiary oil outlet 10, and the water is discharged from the water discharge pipe 12.
