Solar energy driven fresh water preparing apparatus

Abstract

The invention relates to a fresh-water preparation device that is driven by the solar, which is characterized in that the device comprises a container and an air intake hopper that is arranged on the upper side part of the container and is provided with an opening facing downwards, wherein, the air intake hopper is made of the semi-conductor refrigeration plate with the heating side facing upwards and the refrigerating side facing downwards; a through hole that communicate the upper air cavity of the hopper and the air discharging passages surrounding the container is arranged on the lower side part of the air intake hopper; the lower end of the air intake hopper is provided with a water outlet that extends out of the container. When the temperature of the air is decreased to be less than10 DEG C, the vapor in the air can be condensed; for the air exits everywhere, the condensation of the vapor in the air is free from the restriction of the places, and the condensed water is clean and germfree, and can be drunk directly, and can also be used for irrigation. The device has the advantages that the structure is compact, and the device is convenient to carry and to handle, and has low production and maintenance expense, and is free from the restriction of the places, and the like.

Description

Technical field: [0001] The invention relates to a fresh water preparation device driven by solar energy and applied in areas far away from water sources. Background technique: [0002] At present, there are huge problems in drinking water for people far away from water sources. For example, residents living in Gobi and desert environments have little precipitation all year round. Generally, the annual precipitation is less than 200 mm, which cannot meet people's daily life and irrigation needs. In addition, the investigation of areas far away from water sources There is also great inconvenience in carrying and storing drinking water. The applicant Chen Shaodong applied for the "Fresh Water Preparation Device for Sea Islands and Ships" on August 3, 2005. The composition of the control device. Although the device can prepare fresh water for domestic use on islands and ships, the device has a complex structure, high production and maintenance costs, and cannot be portable, w...
