Membrane process water extraction device from air

Abstract

The invention discloses a membrane process water extraction device from air. The membrane process water extraction device from the air comprises a housing, a filter screen communicating with atmosphere outside the housing and a fan, wherein a high-polymer water vapor enrichment membrane component, a small negative pressure pump, a buffer cylinder, a condensation chamber, a semiconductor condensation component and a water treatment component are arranged in the housing; the high-polymer water vapor enrichment membrane component is used for collecting high-humidity air, the small negative pressure pump is used for sending the high-humidity air into the semiconductor condensation component through the buffer cylinder, and water vapor in the high-humidity air can be condensed to liquid or solid water; and the water which finally enters into a water tank after purification treatment through the water treatment component is drinking water which is in line with the standard. The invention provides a water-source-free low-humidity atmospheric water generator which is simple to operate, can continuously supply water for a long time and has the characteristics of small volume, low power consumption, large water yield, a wide range of applications and the like.

Description

technical field [0001] The invention relates to an air water intake device, in particular to a device for passively producing drinking water using polymer water vapor enrichment membrane technology. Background technique [0002] Water is the source of life, and its importance to the human body is self-evident. In special operating environments such as oceans and deserts, or in areas where secondary disasters such as nuclear and chemical pollution and water pollution occur, people often face the situation of "no water source" or "water source is polluted". Especially in the desert environment, because there is no water source, conventional water production equipment and purification equipment cannot be used. For officers and soldiers of the army, "water" has become the top priority of health protection when performing tasks in the above-mentioned environment. [0003] At present, there are many ways to produce water under special environment in the field. Utilizing the wat...

AI Technical Summary

Problems solved by technology

[0004] Directly cooling the air to make water is the method adopted by many air-based water-making devices and equipment on the market, which generally has disadvantages such as small water output, high energy consumption, and limited scope of application.

When the ambient humidity is too low (for example, in desert areas, the humidity is maintained at 20%-30% all year round), or the ambient temperature is too low, the existing equipment or devices often cannot be used normally
