Method for removing suspended substances in air through cooling fan

Abstract

A method for removing suspended substances in air through a cooling fan is disclosed. The cooling fan comprises a fan, a moisture curtain, a water tank and a water pump. The method includes that a decontaminating agent is added into the water tank of the cooling fan or directly into the clean water in the water tank, or the decontaminating agent is added in a slow releasing device provided with a small hole and containing clear water, then the slow releasing device is communicated with the water tank, or the slow releasing device is directly immersed in the water tank, decontaminating agent solution in the slow releasing device enters into the water tank through the small hole slowly; the cooling fan is installed on a window or a wall hole, an air inlet faces outside, and the gap between the periphery of the cooling fan and the window or wall hole is sealed; the window is closed to prevent outdoor air from automatically entering into the door; the water pump of the cooling fan is switched on, the moisture curtain is wetted after one minute later, and the fan of the cooling fan is switched on. The method is simple and cheap. Suspended substances in air are removed, and the air purifying effect is excellent. The method is pollution-free, does not harm environment, and is beneficial to health and worthy of promotion.

Description

technical field [0001] The invention relates to a method and device for purifying air, in particular to a method for removing suspended matter in the air by using a cooling fan. Background technique [0002] At present, the problem of air pollution has attracted great attention from the government and the society. How to remove suspended solids in the air conveniently and at low cost and eliminate the harm of PM2.5 to human health has become a matter of great concern to the public. [0003] The total suspended matter in the air is PM100, that is, the particles in the air whose dynamic diameter is not larger than 100 microns, which can enter the lungs of the human body, and the most harmful to human health is PM2.5, that is, the dynamic diameter in the air is less than Particles larger than 2.5 microns; in PM2.5, the particles that account for a small weight but account for about 90% of the number are PM0.5, that is, particles whose dynamic diameter is not larger than 0.5 mic...

AI Technical Summary

Problems solved by technology

[0004] The use of modern industrial dust removal technology can purify the air to an extremely clean level, but due to its complex structure, large size, large investment, and high operating costs, it is not suitable for home, office and other places; currently on the market The air purifiers used in home, office and other places mainly include: HEPA filter, activated carbon filter, photocatalyst, negative ion, electrostatic adsorption, etc. Generally, indoor air purification uses the filter method, which is characterized by convenient and flexible use and reliable filter effect. The main disadvantages are: large filtration resistance, high power consumption, small air flow through the filter screen or filter element, low filtration capacity, frequent replacement of the filter screen or filter element, high operating costs, and secondary pollution if not replaced in time

[0005] Cooling fans (also called air coolers, water curtain air conditioners, etc.) designed and produced according to the principles of water evaporation cooling and water adhesion dust removal have good effects in cleaning air, lowering the temperature, and protecting the environment in homes and offices. It has been widely used; but since PM0.5 is mainly oil fume, and oil fume is not hydrophilic, when using a cooling fan to purify the air, what can be removed is hydrophilic large particles, but it is basically powerless for PM0.5
