Fresh air system and air processing method thereof

Abstract

The invention discloses a fresh air system and an air processing method thereof. The system comprises an air filtering device and an air purifying device, and the air filtering device comprises an airinlet layer, an exhaust layer and a lifting control device (11); the air inlet layer comprises a first air inlet (1), an air filter chamber (2), a first air inlet chamber (3) and a first air outlet (4) which communicate in sequence; the exhaust layer comprises a second air inlet (5), a first exhaust chamber (6), a filter screen blowback chamber (7) and a second exhaust chamber (8); the air purification device comprises a purification layer and a regeneration layer, the purification layer comprises a second gas inlet chamber (14), a second gas inlet chamber (15) and a second gas inlet chamber(16) which communicate in sequence, and the regeneration layer comprises a negative pressure regeneration chamber (17). A filter screen can be cleaned without frequent replacement of the filter screen; and meanwhile, purified medium does not need to be taken out from the air purifying device, so that the negative pressure regeneration of the purified medium can be completed, and great convenienceis brought to the use of the fresh air system.

Description

technical field [0001] The invention relates to the field of fresh air, in particular to a fresh air system and an air treatment method thereof. Background technique [0002] Air pollution refers to the phenomenon that certain substances enter the atmosphere due to human activities or natural processes, present a sufficient concentration and reach a sufficient time, and thus endanger human comfort, health and welfare or the environment; as my country's industrial Air pollution has become an urgent problem to be solved. There are many types of air pollutants, and their forms may be solid particles, toxic and harmful gases, or a mixture of these forms. [0003] For solid particle pollutants, filter screens are generally used to filter them out. In the air filter devices produced by ordinary manufacturers using filter screens, in order to ensure the air filtration capacity, it is generally required to replace the filter screen every 3 to 6 months.

Problems solved by technology

[0003] For solid particle pollutants, filter screens are generally used to filter them out. In the air filter devices produced by ordinary manufacturers using filter screens, in order to ensure the air filtration capacity, it is generally required to replace the filter screen every 3 to 6 months. This brings great inconvenience to the use of air filter

[0004] For toxic and harmful gases, it is generally necessary to use a purification medium (usually activated carbon) for adsorption in an air purification device; Harmful gases will enter a saturated state. At this time, you can only replace the purification medium in the air purification device, or take out the purification medium, regenerate the purification medium, and then put it back into the air purification device. However, whether it is replacement Whether to purify the medium, or to regenerate the purified medium, it is necessary to frequently remove the purified medium from the air purification device, which brings a lot of inconvenience to the use of the air purification device
