Description
Technical Field
The invention relates to the technical field of air treatment. More particularly, the present invention relates to a method, apparatus and application for air purification.
Background
Before the 70 s of the 20 th century, 8 typical environmental pollution events occurred worldwide, 5 of which were atmospheric pollution events, which became catalysts for the human being to fully open up to cope with environmental pollution. Environmental pollution includes gas, liquid and solid states. The influence of atmospheric pollutants on weather and climate is quite remarkable, and several main aspects of the performance are that the solar radiation reaching the ground is reduced, the atmospheric precipitation is increased, acid rain is generated, and the atmospheric temperature is increased. The main atmospheric pollutants are two main types, one type is aerosol state pollutants, and the main atmospheric pollutants mainly comprise dust, smoke droplets, fog, dust fall, fly ash, suspended matters and the like; aerosols refer to solid particles, liquid particles or their suspensions in a gaseous medium; droplets or solid particles having a diameter of about 0.002 to 100 microns. The second type is gaseous pollutants, mainly comprising sulfur dioxide-based sulfur oxides, nitrogen dioxide-based nitrogen oxides, carbon monoxide-based carbon oxides and hydrocarbon compounds combined by carbon and hydrogen. And as humans continue to break down new substances, the variety and quantity of atmospheric pollutants is also constantly changing. Animals, even south and north, are also affected by atmospheric pollution. When people routinely treat urban atmospheric pollution, in order to quickly and efficiently reduce pollutants in the air, a mode of spraying water mist into the air or a mode of reacting chemical substances with harmful gases is adopted to treat the air pollution. The chemical reaction method is used for treating air pollution, so that a new pollution source is easily caused, a large amount of water resources are needed for spraying the water mist treatment method, and dust on the ground is brought into the air along with the re-evaporation of water. And the fresh water resources of the human society are increasingly deficient. Although 70.8% of the earth's surface area is covered by water, 97.5% of the water is brackish water, and utilization is subject to conditions and environmental constraints. The two-pole ice cover, the mountain glaciers on the land and the ice and snow in the permafrost region account for most of the available fresh water resources, so that the fresh water is difficult to be utilized by human beings, and the fresh water which can be actually utilized by human beings accounts for only 0.26% of the total water quantity of the earth. The water resources available to humans on earth are not only very limited, but also the regional distribution is very uneven. The global annual evaporation of seawater is about 36 thousands of cubic kilometers, which is more than three times the global reserve of available fresh water 10.46 thousands of cubic kilometers. Respiratory activity is a characteristic of life existence, oxygen and water are preconditions for life maintenance. Therefore, how to use the ubiquitous vapor in the air to purify the outdoor air has positive significance for solving the problems of urban atmospheric pollution, water shortage, desert, barren island development, artificial island water and the like.
When people treat urban atmospheric pollution, water mist is sprayed into the air or air pollution is treated by a mode that chemical substances react with harmful gases, so that the problems of new pollution sources, secondary brought air of dust and water resource waste are easily caused; the existing air treatment machine is only aimed at purifying indoor air, because the air purification cost is high, water vapor purification in filtered or condensed air is required to collect and convey low-temperature refrigerating fluid, a large amount of energy is required to collect and convey low-temperature refrigerating fluid, the equipment is complex, the use is restricted by fluid conditions, outdoor air purification is difficult to achieve, people are difficult to obtain high-quality outdoor living environments, and especially outdoor air purification treatment is very urgently required in places with serious atmospheric pollutants such as more roads of vehicles, plant areas with serious dust and the like.
