Example Embodiment
[0035] Example one
[0036] See figure 1 As shown in the figure, an air purification device based on photocatalysis and reversible adsorption includes a housing 110 provided with an air supply channel, and a fan assembly that drives air to flow through the air supply channel (not shown in the figure) ) And a photocatalytic assembly that catalyzes the air flowing through the air supply channel, the air supply channel is divided into several layers of spaces arranged in sequence along the air conveying direction, and the photocatalytic assembly includes a photocatalyst 121;
[0037] Among them, it also includes a reversible adsorption component that adsorbs the air flowing through the air supply channel, and the reversible adsorption component includes a renewable adsorbent 131, wherein the renewable adsorbent 131 and the photocatalyst 121 are respectively arranged in different layers of space, and The regenerable adsorbent 131 is placed on the air inlet side of the photocatalyst 121.
Example Embodiment
[0049] Example two
[0050] See figure 2 , As shown in the legend: an air purification device based on reversible adsorption and photocatalysis, including a housing 210 provided with an air supply channel, a fan assembly (not shown in the figure) that drives air to flow through the air supply channel, and A photocatalytic assembly that catalyzes the air flowing through the air supply channel. The air supply channel is divided into several layers of spaces arranged in sequence along the air conveying direction. The photocatalytic assembly includes a photocatalyst 221,
[0051] Wherein, it also includes a first reversible adsorption component that adsorbs the air flowing through the air supply channel, and the first reversible adsorption component includes a first renewable adsorbent 231, wherein the first renewable adsorbent 231 and the photocatalyst 221 are mixed. In the same space.
