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 a coil structure electrothermal evaporation multi-layer filling fabric. The coil structure electrothermal evaporation multiple layer filling fabric is characterized in that the fabric is formed by an electrothermal evaporation layer, a floating heat insulation layer and a water absorption layer, and the electrothermal evaporation layer, the floating heat insulation layer and the water absorption layer are woven into a whole through different functional fibers and materials. One technical scheme of the invention provides a manufacturing method for the coil structure electrothermal evaporation multiple layer filling fabric, and the other technical scheme of the invention provides application for the coil structure electrothermal evaporation multiple layer filling fabric. The application of the coil structure electrothermal evaporation multiple layer filling fabric is characterized in that the fabric can be applied to seawater desalination, or purification treatment of industrial waste water and agricultural sewage. According to the fabric, the fabric can float on water, moisture is transferred from the water absorption layer to the evaporation layer through binder yarns, and electric power is transformed into heat after the electrothermal evaporation layer is powered on to achieve rapid evaporation of the moisture. The fabric has the advantages of being light in mass, high in strength and simple in structure, industrialized production of the fabric is achieved, and the fabric has a three-dimensional integrated structure and has significant applicationprospects in the fields of seawater desalination and sewage disposal.

Description

technical field [0001] The invention relates to a coil structure electrothermal evaporation multi-layer filling fabric, 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 develo...
