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 discloses a three-dimensional filling structure electrothermal evaporation fabric. The fabric is characterized in that the fabric comprises an electrothermal evaporation layer, a floating heat insulation layer and a water absorbing layer which are sequentially combined, and the three layers above are combined as a whole by binding yarns; the electrothermal evaporation layer is composed of electrothermal evaporation layer wefts and electrothermal evaporation layer warps, the water absorbing layer comprises water absorbing layer warps and water absorbing layer wefts, and floating embedding materials are arranged in the floating heat insulation layer. The fabric can float on the water surface, moisture is conducted to the evaporation layer through the binding yarns, and thermalenergy of sunlight is absorbed by the evaporation layer to achieve moisture evaporation. The fabric has a three-dimensional integrated structure and has the advantages of being light in mass, high instrength and simple in structure, and the fabric can be massively produced; the fabric has significant application prospect in the fields of sea water desalinization and sewage treatment.

Description

technical field [0001] The invention relates to a three-dimensional filling structure electrothermal evaporation fabric, which belongs to the technical field of new materials. 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 of fresh ...
