Title:
FORMALDEHYDE PURIFICATION DEVICE FOR INDOOR AIR TREATMENT
Document Type and Number:
WIPO Patent Application WO/2022/104639
Kind Code:
A1
Abstract:
A formaldehyde purification device for indoor air treatment, wherein an aeration and filtering mechanism (2) is mounted on the inner side of a fixing base (1), a fixing frame (201) is mounted in the middle of one side of the fixing base (1) of the aeration and filtering mechanism (2), an air blower (202) is mounted on the inner side of the fixing frame (201), an air outlet port of the air blower (202) is connected to a flow dividing pipe (203); a water outlet pipe (204) and a water inlet pipe (205) are embedded in and connected to the fixing base (1), a baffle (207) is mounted in the middle of the inner side of the fixing base (1), a placement frame (208) is mounted at the edge of the top end of the baffle (207), a drying and replacement mechanism (3) is mounted on one side of the placement frame (208), a placement plate (209) is mounted in the middle of one side of the placement frame (208), a filter block (212) is placed at the top end of the placement plate (209), and one end of the placement plate (209) is fixedly connected to the baffle (207); flow blocking plates (210) are symmetrically mounted at positions, corresponding to the top end of the baffle (207), on the inner side of the fixing base (1), and flow guide holes (211) are equidistantly provided at positions correspondingly below one end of the placement plate (209) inside the baffle (207). By means of sufficient contact between the outside air and water, most of the formaldehyde in the air is dissolved in the water, and the impurities mixed in the air are adsorbed at the same time, thus avoiding the blockage of the subsequent filter block and the drying and replacement mechanism caused by the impurities; and the secondary filtration treatment of the filter block and the drying and replacement mechanism reduces the proportion of the formaldehyde in the air, and can also decompose the filtered formaldehyde.
