Embodiment 1

[0046] Use a deoiler with a total length of 8m, a molded width of 2.5m, a draft of 0.4m, a displacement of 3.5t, equipped with two 75hp Honda BF7 propellers, and a speed of 10~30km / h, and handle 1×10 4 m 2 The oil slick contaminates the water surface.

[0047] Preparation of 300 kg of Fe by hydrothermal method and high temperature carbonization 3 o 4 @C / Cu special magnetic powder, put the special magnetic powder into the powder storage box 7 of the oil removal ship; drive the oil removal ship to the edge of the oil slick polluted area, start the powder sprayer 8 on the three oil removal ships at the stern , adjust the powder spray rate of each powder sprayer 8 to be 30kg / h, the powder spray distance to be 5m, and the travel speed of the deoiler to be 10km / h. The area covered by the hourly oil spill is 9.63×10 4 m 2 ; When the deoiling ship travels to the end of the polluted area covered by the special magnetic powder sprayed by the powder sprayer 8, close the powder spray...

Embodiment 2

[0049] Use a deoiler with a total length of 8m, a molded width of 2.5m, a draft of 0.4m, a displacement of 3.5t, equipped with two 75hp Honda BF7 propellers, and a speed of 10~30km / h, and handle 1×10 4 m 2 The oil slick contaminates the water surface.

[0050] First, 300 kg of Fe was prepared by hydrothermal method and high-temperature carbonization method 3 o 4 @C / Cu special magnetic powder, put the special magnetic powder into the powder storage box 7 of the oil removal ship;

[0051] Drive the oil removal ship to the edge of the oil slick pollution area, start the duster 8 on the 3 oil removal ships at the stern, adjust the dusting rate of each duster 8 to be 100kg / h, and the dusting distance is 10m. The driving speed is 30km / h. When the oil removal ship starts, the special magnetic powder sprayed by the powder sprayer 8 covers an area of ​​35.87×10 4 m 2 ; When the deoiling ship travels to the end of the polluted area covered by the special magnetic powder sprayed by ...

Abstract

The invention discloses a deoiling vessel and method for recovering and cleaning oil floating on water surface by utilizing special magnetic powder. A powder storage box is arranged in the hull, and the powder storage box is connected with a powder sprayer; a motor is arranged on the hull, and a magnetic separator is connected to the motor. The drum, one side of the magnetic separation drum is provided with a material receiving box, and a scraper is fixed on the box wall of the material receiving box. Put the special magnetic powder into the powder storage tank; drive the oil removal ship to spray the oil-contaminated area; turn off the powder sprayer, make the magnetic separation drum contact the water surface, and drive the oil removal ship to return to the original road at the original speed; the characteristics of oil pollution are absorbed The magnetic powder is transferred to the receiving box; distillation treatment; grinding. The oil removal vessel and the method can efficiently recover and treat the floating oil on the water surface. The oil removal ship and the method are less affected by the waves on the water surface. The method is simple in operation, low in cost, fast in oil removal and high in efficiency.

Description

technical field [0001] The invention belongs to an oil slick treatment method in the field of water quality environmental protection, and in particular relates to an oil removal ship and a method for treating oil slicks on a water surface by using magnetic powder. Background technique [0002] During the production, transportation, storage, refining and use of petroleum, it will cause environmental pollution, especially water surface pollution. With the increasingly stringent water quality standards and regulations, the cleaning technology for oil slicks on the water surface is becoming more and more comprehensive. However, it is still a technical problem to effectively solve large-area oil layers with a thickness less than 500 μm. The main means of oil pollution treatment on the water surface are physical and mechanical methods, the main one of which is to use oil-absorbing materials to treat the floating oil on the water surface, and then use the physical properties of th...
