The main structure is provided with an empty slot to provide an installation device for the filter adsorption frame 4 and the degradation catalytic frame 6, and a support arrangement for the filter adsorption frame 4 and the degradation catalytic frame 6 is established. The formaldehyde removal device is placed against the wall, and the air extraction frame 2 works. The wall air enters the formaldehyde removal device through the rear end panel of the vertical fixed setting frame 1. The airflow first passes through the degradation catalytic frame 6 and catalytically degrades the formaldehyde through the air catalyst. The formaldehyde and other harmful gases carried in the airflow through the degradation catalytic frame 6 are adsorbed by the filter adsorption frame 4. The formaldehyde removal device realizes airflow circulation control of the wall and indoor air through the exhaust frame 2, thereby accelerating the working efficiency of the formaldehyde removal device.

[0029] Activated carbon is set as the main adsorption material in the inner cavity of the filter adsorption frame 4. In order to solve the problem of the limitation of the adsorption effect of limited activated carbon on harmful gases in the room, a lifting handle 5 is set to remove the filter adsorption frame 4 from the empty slot, which is convenient for replacing the activated carbon adsorption plate 42 in the inner cavity of the filter adsorption frame 4, so that the formaldehyde removal device can be continuously recycled and the service life of the formaldehyde removal device is extended. The front end of the exhaust frame 2 is provided with a dustproof mesh cover 3 to achieve dust-proof protection for the exhaust component and ensure that the airflow can circulate normally. The vertical fixed setting frame 1 is fixedly set above the fixed base 7, and the fixed base 7 supports the stable installation of the vertical fixed setting frame 1. The formaldehyde removal device may come into contact with the wall or furniture surface during use. The rubber anti-collision strip 10 can replace the corners and edges of the fixed base 7 to come into contact with the wall or furniture to avoid damage to the wall and furniture.

[0030] An air intake dustproof net is arranged at the rear end of the vertical fixed setting frame 1, so as to facilitate the indoor air to smoothly enter the formaldehyde removal device, and at the same time, enhance the dustproof protection of the air flow channel of the formaldehyde removal device, which can effectively prolong the service life of the formaldehyde removal device.

The three air catalyst film groups are arranged as elliptical arc-shaped sheets, which can effectively intercept the airflow and improve the catalytic degradation efficiency of the airflow.

[0033] The exhaust fan 24 rotates at a high speed to suck the indoor air into the formaldehyde removal device. The airflow is first intercepted by the first air catalyst film group 62. A part of the airflow passes through the first air catalyst film group 62 and flows forward, and is intercepted again by the third air catalyst film group 64, so that the two groups of air catalyst film groups can perform catalytic degradation on it. Another part of the air flows through the gaps between adjacent catalyst films of the first air catalyst film group 62 to the catalyst films of the second air catalyst film group 63 for catalytic degradation. Another part of the air flows through the gaps between adjacent catalyst films of the second air catalyst film group 63 to the third air catalyst film group 64 for catalytic degradation, thereby realizing the conduction and comprehensive catalytic control of the airflow entering the formaldehyde removal device. The polluted gas carried by the air after catalytic degradation is adsorbed by the filter adsorption frame 4, which effectively reduces the working pressure of the filter adsorption frame 4 and improves the treatment efficiency of the indoor air.
