Problems solved by technology

The multi-stage flash evaporation 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 permeation performance. The lifespan and anti-pollution problems of the membrane cannot be effectively solved. The reverse osmosis membrane, high-pressure pump, and energy recovery device need to be replaced regularly
[0004] 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. Obviously, to achieve large-scale seawater desalination, it is first necessary to seek more reliable and economical new energy sources

Abstract

The invention provides coil structure heat-collecting evaporation filling fabric. The coil structure heat-collecting evaporation filling fabric comprises a heat-collecting evaporation layer, a floating heat-insulating layer, and a water-absorbing layer which are successively installed. The heat-collecting evaporation layer, the floating heat-insulating layer, and the water-absorbing layer are bound as a whole body through mutually interlaced binding yarns with a water guiding function; and a coil structure for increasing the contact area of sunshine and air is formed on the surface of the heat-collecting evaporation layer by the binding yarns. The invention further provides a preparation and using method for the coil structure heat-collecting evaporation filling fabric and a usage thereof.The provided fabric can be floated on water, water is conducted from the water-absorbing layer to the heat-collecting evaporation layer through the binding yarns, and the water is evaporated by absorbing heat of the sunshine through the heat-collecting evaporation layer. The contact area of the fabric and the air is increased through the coil structure, and the water evaporation efficiency is improved. The provided fabric has a three-dimensional integrated structure, is light in weight, high in strength and simple in structure, and can be industrially produced. The fabric has the important application prospect in the sea water desalination and sewage treatment field.

Description

technical field [0001] The invention relates to the technical field of new materials, more specifically, to a heat-collecting and evaporative filling fabric with a coil structure and its preparation, use and application. 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 developm...
