Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water treatment equipment, in particular to a mobile emergency water treatment equipment, and more particularly to an emergency water collecting equipment based on a Stirling engine. BACKGROUND

[0002] Water is a basic resource for human survival, and the role of water bodies is reflected in various aspects, from production and life to actual research, etc. Under normal circumstances, people obtain necessary water resources in life by ingesting food, municipal pipe networks and surface water sources. However, in some special situations, such as replenishing water during outdoor travel, the only way is to rely on the stored water carried, especially in the sea, jungle and other areas. Once in distress in the wild, water shortage will lead to serious consequences. Similarly, in the event of an emergency, such as rescue and relief, due to the destruction of the daily water resource acquisition channel, the existing emergency water treatment equipment can only perform water purification work in a single way when treating water at the rescue site. However, in the actual rescue site, sometimes a large amount of water with low purity is needed for production and life, and sometimes water with high purity is needed for experiments and daily drinking.

[0003] At present, the main method for people to solve the problem is to obtain drinkable water from natural water sources through fire or solar distillation, filtration and other methods. When sailing at sea, people will carry a seawater desalination device to convert seawater into drinking water. These methods solve the problem to some extent, but they are limited by equipment and environment. In places with high air humidity, such as at sea and in forests, collecting water from the air is a good choice to solve the above problems. The existing emergency water treatment equipment mostly has the problems of single function, inconvenience to move, defects in actual use, inconvenience to use in actual emergency treatment, only capable of meeting a single water treatment process, lack of effective function integration, affecting the actual water treatment efficiency, and certain limitations. Or collect water from humid air through solar power generation and refrigeration to realize power refrigeration. Solar power generation has high requirements for environmental conditions and can only collect water during the day when the sunlight is sufficient. Therefore, we propose a mobile emergency water collecting equipment, which can be used to collect water vapor in the air all day long to alleviate the problem of emergency drinking in the case of encountering no water source or water source pollution in the wild.
