Abstract

The invention provides a haze-removing fresh-air filtration apparatus, belonging to the technical field of environmental protection equipment. The bottom of one side of the outer shell of the apparatus is provided with an outdoor fresh air inlet and an exhaust fan; the top of the outer shell is provided with an air blower and a polluted air outlet; a primary electrostatic precipitator is arranged at the inner side of the outdoor fresh air inlet; the inner side of the primary electrostatic precipitator is successively provided with a primary-effect filter screen, a HEPA filter, a photocatalyst filter screen and an activated carbon filter layer; an air heat exchanger is arranged on the upper end of one side of the activated carbon filter layer; a secondary electrostatic precipitator is arranged above the right side of the air heat exchanger; and two sides of the secondary electrostatic precipitator are respectively provided with an UV lamp and a negative-ion generator. The haze-removing fresh-air filtration apparatus provided by the invention can convey outdoor fresh air into a room to realize indoor ventilation and air exchange, so indoor air quality is improved, indoor air is purified, pollutants are effectively removed, and a healthy comfortable indoor environment is created.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a fresh air filter equipment for haze removal. Background technique [0002] In recent years, with the rapid development of cities, the harmful substances in the atmosphere have been increasing, especially the increasing PM2.5, which poses a serious threat to people's health and immeasurable potential harm. [0003] The air purifier can be said to be the first to be popularized, and it is also the product with the highest rate of household registration. After all, when the smog comes, buy an air purifier and go home, and it will be effective immediately. This also has a psychological comforting effect on the public's panic and anxiety about pm2.5. [0004] However, from the perspective of a healthy, three-dimensional, scientific, and sustainable family breathing environment, air purifiers that simply purify PM2.5, or assist in removing formaldehyde an...

Problems solved by technology

[0004] However, from the perspective of a healthy, three-dimensional, scientific, and sustainable family breathing environment, air purifiers that simply purify PM2.5, or assist in removing formaldehyde and odor, do have great limitations. sex

This is due to the working principle of the air purifier itself and the natural internal circulation defects. The purifier cannot meet people's needs for fresh air and indoor oxygen content or ventilation.
