Portable dew collecting device with conical reinforced condensing pipes

Abstract

The invention provides a portable dew collecting device with conical reinforced condensing pipes, and belongs to the technical field of condensing phase transformation. The portable dew collecting device with the conical reinforced condensing pipes structurally comprises the conical reinforced condensing pipes, condensing pipe hanging racks, a support frame and a dew collecting tank, wherein microgrooves are formed in the outer surfaces of the condensing pipes in the axis direction and are used for downwards discharging condensate; sub-millimeter micro-bulging coarse structures are arranged on rib walls between the micro grooves; hydrophobic modification and hydrophilic modification are respectively carried out on the upper parts and lower ends of the condensing pipes so as to facilitatethe generation of dropwise condensation on the surfaces of the condensing pipes, intensity the condensation process, facilitate the formation of downward capillary differential pressure in the water discharging grooves and promote the discharge of condensed water from the surfaces of the condensed pipes; the condensing pipes are arranged in a staggering manner to increase the windward area; and the condensing pipe hanging racks are connected to the support in a bayonet type, thereby facilitating the disassembly and improving the portability. The whole device has novel structure, good portability, clear principle of water vapor collection and high reliability, can effectively intensify the condensation process of water vapor in the air on the surfaces of the condensing pipes and improves the collection efficiency of the condensed water.

Description

technical field [0001] The invention belongs to the technical field of condensation phase change, and relates to a water vapor collection device in the air, in particular to a portable dew collection device with a conical reinforced condensation pipe which can improve the dew collection efficiency. Background technique [0002] Water is an essential resource for human survival, and how to quickly and efficiently obtain safe water is crucial for arid areas or field activities far away from safe water sources. Harvesting water vapor from the air, even in arid desert regions, is an important and feasible way. For example, at night, the solid surface loses heat to the outside due to radiation. When the surface temperature is lower than the dew point temperature, the water vapor in the air will condense on the solid surface, so that the water vapor in the air can be collected for use, but the water vapor in the air can be collected Water vapor requires additional energy and syst...
