Solar regenerative adsorption type device for taking water from air and using method of solar regenerative adsorption type device

Abstract

The invention discloses a solar regenerative adsorption type device for taking water from air. The solar regenerative adsorption type device for taking the water from the air comprises an air inducing unit, a cooling channel of a heating heat exchanger, an adsorbent filling bed unit and a condensing coil packaging shell of an air cooling condensing unit which are connected in sequence, a heating channel of the heating heat exchanger communicates with a solar heat collector to form a solar fluid circulation channel, a silica sol solidified activated carbon fiber felt / lithium chloride and sodium acetate double-salt solid adsorbent material is arranged in the adsorbent filling bed unit, a condensing coil is arranged in the condensing coil packaging shell, and the refrigeration heat exchanger communicates with the condensing coil to form an air cooling heat exchange fluid circulation channel. One-time water taking circulation carried out through the method comprises an adsorption stage and a regeneration stage, and in the adsorption stage, the solid adsorbent material adsorbs water vapor in flowing air; in the regeneration stage, hot dry air heated by the heating heat exchanger enables moisture in the solid adsorbent material to be desorbed into hot wet air, and then the hot wet air flows through the condensing coil to be condensed to generate condensed water.

Description

technical field [0001] The invention relates to the field of an air water intake device, in particular to a solar regeneration adsorption type air water intake device. Background technique [0002] Fresh water is one of the most important resources to maintain human vital signs. However, the distribution of fresh water resources in the world is not uniform, and some areas are in a state of severe water shortage all year round, which hinders the development of regional economy and the improvement of people's living standards. For some remote areas with underdeveloped economy and imperfect supporting facilities that are short of fresh water resources, as well as islands, deserts, pastures and other areas with scattered population and high mobility, or where natural disasters are frequent and post-disaster rescue and reconstruction work is heavy. In natural disaster areas, large centralized water supply systems are obviously not economical. On the basis of continuously promot...

Problems solved by technology

However, the existing adsorption air water intake device has the disadvantages of low water intake per unit mass of adsorbent or long system adsorption / regeneration operation time (adsorption at night, regeneration during the day), and is greatly affected by the day and night environment.
