Description

Fence containing hydrophilic material {FENCE HAVING HYDROPHILIC MATERIAL}

The present invention relates to a fence comprising a hydrophilic material, and more specifically, by using a hydrophilic oil-separating material such as a float and a skirt constituting the fence, the entire fence has a function of passing water but not oil, The present invention relates to a fence including a hydrophilic material capable of quickly and reliably collecting oil or dangerous substances in the water stably even in a high flow rate emphasis or high wave area.

In the event of an oil or hazardous spill (HNS) spill from the ocean or stream, the oil or hazardous pest floats over the surface of the ocean and streams and spreads rapidly, causing serious pollution to the surrounding environment.

Therefore, it is important to remove oil or HNS promptly when an accident occurs.

Normally, when oil has leaked into the ocean or river, the flow of the current is calculated and an oil fence is installed to install the primary spill barrier, and then the oil accumulated in the oil fence is sprayed with an emulsifier to settle on the seabed, or oil Oil is recovered by using oil recovery equipment such as skimmers and adsorption cloths.

However, in the case of the existing oil fence, the balance of the fence is often lost due to water pressure in areas with high emphasis or digging, and the effect is rapidly reduced, which makes it difficult to use the existing oil fence.
