Desert moisture acquisition device

Abstract

The invention provides a desert moisture acquisition device. The desert moisture acquisition device comprises a moisture acquisition device body and a condensing device. The water acquisition device body comprises a cylinder, a heater and an air exhauster. A constant pressure valve is arranged on the side face of the cylinder, an inner cavity of the cylinder is communicated with external air through the constant pressure valve, an acquisition opening is formed in the lower end of the cylinder, a partition net is arranged in the portion, close to the acquisition opening, of the inner cavity of the cylinder, the heater and the air exhauster are located at the upper end of the cylinder, an air inlet of the air exhauster is communicated with the inner cavity of the cylinder, an air outlet of the air exhauster is communicated with an air inlet of the condensing device, and a water outlet and an exhaust port are formed in the condensing device. The desert moisture acquisition device has the following advantages that moisture in sand is evaporated in negative pressure environments, moisture evaporation can be quickened, follow-up condensing efficiency is higher, water outflow is quicker, and water intake efficiency is obviously improved; the desert moisture acquisition device is compact in structure, convenient to use, free of influences of surrounding environments, capable of being used in multiple environments and high in universality.

Description

technical field [0001] The invention relates to a water collecting device, in particular to a device for collecting water in a desert. Background technique [0002] Fresh water is a necessity for human survival. In water-scarce areas, it is becoming more and more difficult to obtain fresh water, especially in deserts. A Chinese patent with the authorized notification number CN 101629875B discloses a solar air moisture collection device. Its technical scheme is as follows: a container is formed on the base by a light-transmitting plate that can be freely opened and closed, and a multi-layer net is arranged inside the container. A water-absorbing substance is placed on the grid; the inner center of the container is provided with a water collection pipe, the top is provided with a condenser, and the base has a connecting pipe leading to a collection bottle. The shape of the container is large at the bottom and small at the top. Conical, the central position of the grid frame i...

Problems solved by technology

Although the scheme disclosed in the above-mentioned patent can realize the acquisition of water, it needs to absorb water at night, and obtain water through evaporation by sunlight during the day, which takes a long time and has low water intake efficiency. Poor ease of use
