Nanofiber-foam-based continuous recovery device for floating oil on water surface and manufacturing method thereof

Abstract

The invention provides a nanofiber-foam-based continuous recovery device for floating oil on the water surface and a manufacturing method thereof. The nanofiber-foam-based continuous recovery device for the floating oil on the water surface is characterized by comprising protective net covers, super-oleophylic hydrophobic nanofiber open-cell foam is arranged inside the protective net cover, oil collecting capillary nets are distributed inside the super-oleophylic hydrophobic nanofiber open-cell foam and connected with a main oil conveying pipe, the main oil conveying pipe is connected with a pump, and the pump is connected with an oil storage tank. The manufacturing technology is simple, the production cost is low, operation is convenient, expandability is high, recovery devices of different specifications and numbers can be selected according to requirements to be connected with the oil pump and the oil storage tank, and therefore a recovery system for the floating oil on the water surface is formed. Adsorption separation can be performed on the floating oil on the water surface efficiently and continuously, oil products obtained through separation are high in purity, and the nanofiber-foam-based continuous recovery device has broad application prospects in the fields of environment pollution treatment and oil product purification.

Description

technical field [0001] The invention belongs to the technical field of water surface oil slick pollution control, and in particular relates to a nanofiber foam-based water surface oil slick continuous recovery device and a preparation method thereof. Background technique [0002] Petroleum resources, as the "blood" of modern industry, not only promote the rapid development of human production and life, but also bring many environmental problems to human beings. Due to natural or human factors, frequent oil pollution accidents in water bodies have brought great losses to the ecological environment and economy. Existing methods for removing oil slicks on the water surface mainly include: combustion method, chemical method, biological method, oil skimming method, membrane separation method and adsorption method. Among them, the combustion method and the chemical reagent flocculation method have high efficiency, but there are residues, which are easy to cause secondary pollutio...

AI Technical Summary

Problems solved by technology

However, the surface oil collection devices involved in the above-mentioned patents all adopt a single oil-collecting pipe built into the oil-absorbing material, and the connection port with the adsorbing material is only through a single opening on a single pipe. Gathering and transportation are limited, and it is easy to cause blockage of pipe holes, and the work efficiency is low

On the other hand, under the condition of adsorbing oil pollution, the high suction force will cause stress concentration at the junction of a single pipe and the material, resulting in deformation of the adsorption material and separation from the oil suction pipe, resulting in the unstable operation of the device

In addition, the adsorption material used in the device disclosed in the above patent is a commercially available sponge or non-woven fabric. Due to the large structural size of the material, small specific surface area, low porosity, and single structure, the separation efficiency of the obtained device for floating oil on the water surface and the general The amount is limited and the performance is poorly adjustable, which cannot meet the actual application requirements

Nanofibrous foam is a three-dimensional material with high specific surface area, high porosity, and high pore connectivity. It has flexible structure adjustability and stability. So far, there is no relevant research report on the floating oil separation device based on nanofiber foam
