Description

A kind of method utilizing spherical bubble reduction PM2.5

Technical field

The present invention relates to a kind of method reducing PM2.5, more specifically, relate to a kind of method utilizing spherical bubble reduction PM2.5, belong to field of environment protection.

Background technology

PM2.5 and fine particle, also known as particulate, fine grained, specifically refer to that in surrounding air, equivalent aerodynamic is less than or equal to the particle of 2.5 microns.It can be suspended in air the long period, and content concn is higher in atmosphere for it, just represents air pollution more serious.Although PM2.5 is the little part of earth atmosphere component content, it has important impact to air quality and visibility etc.Compared with thicker Atmospheric particulates, PM2.5 particle diameter is little, and area is large, active strong, easily attaches poisonous and harmful substances, and time of staying is in an atmosphere long, fed distance is far away, thus larger on the impact of health and atmosphere quality.In recent years, in China's air, the content of PM2.5 constantly increases, and has had a strong impact on the healthy of city dweller.In existing reduction air, the method for PM2.5 is water spray aloft, and this method can only be sprayed on higher building or by aircraft, and jet length is limited, also waste a large amount of water resources, cost is higher, and in water smoke, water droplet size is less, and the effect reducing PM2.5 is poor.

Summary of the invention

In view of this, main purpose of the present invention is that providing a kind of utilizes spherical bubble to reduce the method for PM2.5, and the method that can solve PM2.5 in existing reduction air wastes great lot of water resources, and the problem that air purification effect is poor.

For achieving the above object, the technical scheme that the present invention takes is: the concrete steps of the method for the invention are as follows:

Step one, in water, add foaming agent, generate the foaming aqueous solution, the mixed proportion of foaming agent and water is 0.01% ~ 10%;

Step 2, the foaming aqueous solution is heated to 10 ° of C ~ 70 ° C;

Step 3, steel wire to be immersed in the foaming aqueous solution, and allow thermal current blow over to be soaked with the steel wire of the foaming aqueous solution;

The bubble that step 4, the foaming aqueous solution produce is diffused in air under the effect of aerostatic buoyancy, and by the suspended particulate removing in air.

Compared with prior art, the present invention has following beneficial effect: 1, spherical bubble inner air is heated to uniform temperature by the present invention, and spherical bubble can freely rise in an atmosphere, not only can be placed on high building and implement, and also can be placed in ground and implement; 2, thermal current drives spherical bubble to rise, after spherical bubble leaves thermal current scope, because spherical bubble inside is hot-air, ball bubble continues to rise, under the insulation effect of spherical bubble adventitia, in bubble, hot-air cooling slowly, spherical bubble becomes slow decline from rising gradually, and in this process, the ball bubble hang time is long, to wave distance with air-flow, effectively expand spraying range; 3, the spherical bubble surface area of the present invention's generation is large, and the hang time is long, strong in conjunction with PM2.5 ability; 4, the present invention is when using less water source, can expand spray area, improves the hang time, strengthens the removal effect of PM2.5, reduces cost, saved great lot of water resources.
