A nanofiber foam-based oil and gas capture device and its preparation method

[0028] Such as figure 1As shown, it is a schematic structural diagram of a nanofiber foam-based oil and gas capture device. The nanofiber foam-based oil and gas capture device includes a gas collection pump 1 connected to a gas delivery pipe 2, and the gas delivery pipe 2 is connected to an oil and gas capture component, and the oil and gas capture component is connected to The exhaust pipe 5 and the collecting pipe 6, the collecting pipe 6 is connected to the oil substance recovery tank 7, wherein the oil and gas collection assembly includes a protective box 3, and the nanofiber-based foam material 4 is arranged in the protective box 3. The nanofiber-based foam material 4 is obtained by super-oleophilic and hydrophobic modification of the nanofiber foam material by high-voltage electrostatic spraying method. The high-voltage electrostatic spraying method adopts the EcoHT500 high-voltage electrostatic spraying system produced by German DURR company to spray super-oleophilic an...

The nanofiber-based foam material 4 is obtained by performing super-oleophilic and hydrophobic modification on nanofiber open-cell foam by using a magnetic field-induced self-assembly method. The type constant magnetic field generator applies an external magnetic field to wrap the Fe inside 3 o 4 The super-oleophilic and hydrophobic magneti...
