Description

Machinable Offshore Enteromorpha Salvage Vessel

technical field

The invention relates to a marine algae cleaning ship, in particular to a processable offshore Enteromorpha salvage ship.

Background technique

Enteromorpha is a collective name for several species of algae of the genus Enteromorpha, Chlorophyta Chlorophyta, Ulva, and the genus Enteromorpha. They are widely distributed in the shallow intertidal zone of temperate seas, and also exist in inland waters. The algal body is grass-green, tubular and membranous, clustered, with obvious main branches and slender branches, up to 1 meter high.

In recent years, due to global climate change, water eutrophication and other reasons, the green tide of the large marine alga Enteromorpha broke out. In mid-June 2008, the coastal waters and coasts of Qingdao encountered a sudden and rare natural disaster of Enteromorpha, which once affected the sea training of Olympic sailing athletes. From 2011 to 2013, Enteromorpha green tide disasters broke out every year in June and July in the central Yellow Sea. Although Enteromorpha is non-toxic, the massively multiplied Enteromorpha can block sunlight, affect the growth of seabed algae, and destroy marine ecosystems. The outbreak of Enteromorpha can also seriously affect the landscape and interfere with tourism and water sports.

On the other hand, Enteromorpha itself has great utilization value:

1. The dried and pulverized Enteromorpha powder can be eaten directly, or made into Enteromorpha cake, Enteromorpha slices, or refined into food additives.

2. Enteromorpha is rich in carbohydrates, protein, crude fiber and minerals, as well as fat and vitamins. In aquaculture and animal husbandry, many experiments and studies have proved that Enteromorpha has no toxic and side effects on animals, and it can be used as a feed additive to improve the nutritional structure of the feed and increase the utilization rate of the feed.

3. The fiber of Enteromorpha has the effect of detoxifying nicotine, which is good for smokers; the polysaccharide of Enteromorpha extracted from Enteromorpha has the effect of lowering blood fat.

4. The post-processing of Enteromorpha can be made into bio-crude oil.

However, the treatment of Enteromorpha at the present stage is mainly based on artificial tissue, and a large number of fishing boats are recruited for manual cleaning, and then they go ashore and accumulate on the beach, and then use heavy machinery (trucks, etc.) for the next step of treatment. Treating it in this way not only consumes a lot of manpower and material resources, but also increases the social and economic burden. At the same time, the Enteromorpha accumulated on the beach will affect the beach environment and destroy the natural landscape. In addition, once Enteromorpha is cleaned up on the beach, sand, stones and sundries are easily mixed into it. The reuse value of Enteromorpha is almost zero, so it can only be disposed of in landfill, which may easily cause secondary pollution of Enteromorpha to the environment.

Contents of the invention
