Embodiment 1

[0025] Such as figure 1 As shown, the fresh air filter system of the present invention includes a main frame shell 8, a primary filter 1 installed behind the air inlet of the primary frame 8, a gas suction fan 2 connected to the primary filter 1, and a gas suction fan 2 connected to the primary filter 1. 2 phase-connected middle filter 3, electrostatic precipitator 4 is installed after middle filter 3, HEPA filter 5 is installed after electrostatic precipitator 4, activated carbon filter 6 is installed after HEPA filter 5, silver catalyst filter 7 links to each other with activated carbon filter screen 6, and silver catalyst filter screen 7 links to each other with the air outlet that is installed on the host shell 8.

[0026] An air cavity is respectively arranged between the middle filter screen 3 and the electrostatic precipitator 4; the electrostatic precipitator 4 and the HEPA filter screen 5; the HEPA filter screen 5 and the activated carbon filter screen 6.

Embodiment 2

[0028] After repeated tests, the effect of electrostatic precipitator is mainly affected by temperature, humidity, wind speed and the specific resistance value of dust. Control the wind speed of electrostatic precipitator not to exceed 1 m / s, and the PM2.5 filtering effect at this time can reach more than 95%. It can reach 100% under some conditions. At this time, we equip a HEPA filter as an auxiliary filter. Under special conditions, the remaining 0-5% PM2.5 is handed over to the HEPA filter for processing. In this way, the HEPA filter The service life of the net has increased by 50-100 times from the original 6 months to 300-600 months, far exceeding the actual required time.

[0029] a 20m 2 A room with a floor height of 3m requires about 90m of fresh air 3 / h, the present invention prepares 150m 3 Air volume fans, of which 20m 3 is the wind resistance loss, the area of ​​the air duct of the electrostatic precipitator is 0.025m 2 , equipped with an electrostatic precip...

Embodiment 3

[0033] When the invention is installed, it is sealed first. Due to the advanced technology of the air inlet host, it can block particles below PM2.5 and be effective for a long time without changing the filter screen. The installation is equipped with an air outlet, so that a reasonable air flow is formed indoors, and the indoor air is clean. Oxygen-enriched, measured PM2.5<20μg.

[0034] The number of door openings is less than 10 times, the measured PM2.5 is less than 10 μg, and the PM2.5 at the air outlet of the host is 0.

Abstract

The invention provides a fresh air filtering system, which is characterized in that it comprises a main engine shell, a primary filter installed behind the air inlet of the main engine shell, a gas suction fan connected with the primary filter, and a gas suction fan connected with the gas suction fan. The middle filter, the electrostatic precipitator is installed after the middle filter, the HEPA filter is installed after the electrostatic precipitator, the activated carbon filter is installed after the HEPA filter, the silver catalyst filter is connected with the activated carbon filter, and the silver catalyst filter It is connected with the air outlet installed on the shell of the host. The invention is suitable for installation in various occasions, and is very simple; the energy source continuously provides fresh air, and can also block various pollen, virus and bacteria, and can block PM2.5 pollutants for a long time without replacing consumables; unique design, basically No noise, the present invention can be applied to indoor air purification cycle, easy to install and wide adaptability.

Description

technical field [0001] The invention relates to a fresh air filtering system and its application, in particular to a purification system capable of improving indoor air quality and its application. Background technique [0002] With the continuous development of the economy and the increasing degree of global industrialization, it has caused serious pollution to the atmosphere. Especially in recent years, smog weather has frequently appeared, and the PM2.5 pollution index has become an important indicator for evaluating air quality. As early as 2006, the U.S. Environmental Protection Agency stated that the ideal standard for air quality is that PM2.5 should not exceed 33 μg / m 3 , the EU standard is 22μg / m 3 , and the guideline value of the "Air Quality Guidelines" formulated by the World Health Organization (WHO) in 2005 is an annual average value of 10 μg / m 3 , with a daily average of 25 μg / m 3 . Compared with the above standards, 1% of urban residents in China current...
