Problems solved by technology

The multi-stage flash distillation technology in the distillation method consumes a lot of power and the operation flexibility of the equipment is small. The low-temperature multi-effect distillation equipment of the multi-effect distillation technology has a large volume and high equipment cost; the electrodialysis method has a simple process and a high desalination rate, but The water recovery rate is low, the team has no ability to remove uncharged substances, and consumes a lot of energy, so it is not suitable for large-scale seawater desalination projects; the reverse osmosis method requires a "semi-permeable membrane" with selective permeability, and the life of the membrane and The anti-pollution problem cannot be effectively solved, and the reverse osmosis membrane, high-pressure pump, and energy recovery device need to be replaced regularly
The above technologies mainly use thermal energy and electric energy as energy sources for seawater desalination, and the desalination efficiency is not high, the equipment is complicated, and the desalination process is slow

Abstract

The invention relates to coil-structure electrothermal evaporation hollow fabric. The fabric is characterized by comprising an electrothermal evaporation layer, a thermal-insulating water-guiding layer and a floating layer; the electrothermal evaporation layer, the thermal-insulating water-guiding layer and the floating layer are weaved into an integral body through different functional fiber. Theother technical scheme of the invention provides a manufacturing method of the above coil-structure electrothermal evaporation hollow fabric. Another technical scheme of the invention provides applications of the above coil-structure electrothermal evaporation hollow fabric. The fabric provided by the invention can float on the water surface, and the moisture is conducted to the electrothermal evaporation layer through the heat-insulating water-conducting layer, and the electric energy is converted into heat after the evaporation layer is energized, thereby realizing rapid evaporation of moisture. The fabric obtained by the invention has a three-dimensional hollow integrated structure, simple structure, high strength, long service life and industrial production; and has important application prospects in the field of seawater desalination and sewage treatment.

Description

technical field [0001] The invention relates to an electrothermal evaporation hollow fabric with a coil structure, a manufacturing method of the fabric and an application of the fabric. Background technique [0002] The total amount of fresh water resources on land only accounts for 2.53% of the total amount of water bodies on the earth, and most of the fresh water is frozen in the ice sheets and glaciers of the north and south poles and high mountains, making it difficult to use. The uneven distribution of fresh water resources in time and space and the irrational use of human beings make many areas of the world face a serious crisis of fresh water resources. With the development of the economy, the use of fresh water has increased sharply, and the economic growth, population increase and water pollution have led to a serious shortage of fresh water resources in my country, which has become an important obstacle to the sustainable development of the economy. The development...
