Enteromorpha prolifera desalting device

Abstract

The invention discloses an enteromorpha prolifera desalting device, and belongs to the field of agricultural engineering. The device is characterized by comprising a desalting tank, a spray flushing tank and a salt precipitation tank. Desalting is carried out in two steps, wherein the first step is to carry out water pool immersing desalination in the desalting tank, and the second step is to carry out running water flushing desalination in the spray flushing tank. The running water flushing desalination is carried out through devices such as high-pressure spray heads, an enteromorpha prolifera screen conveyor belt, an outlet pipe of the spray flushing tank, an inlet pipe of the spray flushing tank, and the like; and purification, desalination and recycling of brine are carried out in thesalt separation tank. Compared with the prior art, the device provided by the invention has the advantages that resources used for enteromorpha prolifera desalination are few, cost is low, and popularization and application are facilitated.

Description

technical field [0001] The invention relates to a desalination device, which belongs to the field of agricultural engineering. Background technique [0002] Enteromorpha is an algal plant with green grass, tubular membranous, clustered, with obvious main branches, slender branches, up to 1 meter high, and the base is attached to rocks with holders. It grows on tidal flats and gravels in the mid-tidal zone ; In recent years, due to global climate change, water eutrophication and other reasons, the green tide of large marine algae Enteromorpha breaks out, and Enteromorpha floats and gathers on the shore, blocking waterways and destroying marine ecosystems, seriously threatening coastal fisheries and tourism. Development; in order to prevent channel blockage, further deterioration of Haiyang's ecological environment, and protect the development of my country's coastal fishery and tourism, my country has carried out various methods of treatment of Enteromorpha, such as offshore in...

[0002] Enteromorpha is an algal plant with green grass, tubular membranous, clustered, with obvious main branches, slender branches, up to 1 meter high, and the base is attached to rocks with holders. It grows on tidal flats and gravels in the mid-tidal zone ; In recent years, due to global climate change, water eutrophication and other reasons, the green tide of large marine algae Enteromorpha breaks out, and Enteromorpha floats and gathers on the shore, blocking waterways and destroying marine ecosystems, seriously threatening coastal fisheries and tourism. Development; in order to prevent channel blockage, further deterioration of Haiyang's ecological environment, and protect the development of my country's coastal fishery and tourism, my country has carried out various methods of treatment of Enteromorpha, such as offshore interception and salvage, shore cleaning, etc., but the treatment of the salvaged Enteromorpha It has become a problem again. It has been stacked and rotted for a long time, and it has become a waste that emits a foul smell, causing environmental pollution.

Enteromorpha is rich in carbohydrates, protein, crude fiber, amino acids, fatty acids, vitamins and various minerals, among which the iron content is recorded as the most in Chinese food in the Chinese food nutrition composition table, and it also contains fat and vitamins. In protein, there are complete types of amino acids, and the content of essential amino acids is high. Among them, the limiting amino acid of Enteromorpha is lysine, and the amino acid score is 79. The limiting amino acid of Enteromorpha is methionine, and the amino acid score is 80. The fatty acid composition of Enteromorpha Among them, the content of polyunsaturated fatty acid, monounsaturated fatty acid and saturated fatty acid is 50.5%, 12.7% and 36.8% respectively, which is a kind of waste with rich nutrition content. The main factors restricting its comprehensive utilization are Enteromorpha and There is a large amount of salt, and desalination treatment is required before use. Desalination treatment is a great waste of resources and high cost
