Embodiment 1

[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...

Embodiment 2

[0036] Such as figure 1 As 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 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...

Embodiment 3

[0044] Such as figure 1 As 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 treatment on the nanofiber foam material by steam diffusion method. The colloidal silica solution is placed in a heatable closed space at the same time, the temperature of the closed space is raised to 210°C, and the internal pressure is raised to...

Abstract

The invention provides a nanofiber foam based oil gas trapping device and a preparation method thereof. The nanofiber foam based oil gas trapping device is characterized in that: it includes an gas collection pump in connection with a gas delivery pipe, the gas delivery pipe is connected to an oil-gas trapping assembly, the oil-gas trapping assembly is connected to an exhaust pipe and a collection pipe, and the collection pipe is connected to an oil substance recycling bin. Specifically, the oil-gas trapping assembly includes a protective box, and the protective box is internally provided with a nanofiber based foam material. The nanofiber foam based oil gas trapping device has the characteristics of simple preparation process, low cost, convenient operation, integrated oil-gas adsorption recovery, high efficiency and continuity, and has wide application at gas stations, oil plants, wharfs and other sites, and in manufacturing industry, surface coating industry and other fields.

Description

technical field [0001] The invention belongs to the technical field of oil and gas pollution control and recycling, and in particular relates to a nanofiber foam-based oil and gas trapping device and a preparation method thereof. Background technique [0002] Oil and gas refers to a mixture containing a variety of organic hydrocarbons and air, which widely exists in gas stations, oil depots, refineries, oil fields and other places. During the process of storage, loading and unloading, transportation and retailing of oil products, due to the influence of external environmental factors (temperature, air pressure, etc.) The decline in product quality and direct energy and economic losses have also caused serious air pollution and fire hazards to the surrounding environment. Can cause cancer. According to statistics released by relevant departments, with the progress of my country's production technology in recent years, the emissions of oil products from crude oil extraction ...
