The working principle is as follows:
when the formaldehyde removing device is used, firstly, the formaldehyde removing device is placed in a formaldehyde chamber, air containing formaldehyde is sucked into a first-stage formaldehyde removing chamber 1 from a first air inlet 12 through an exhaust fan 11 and is contacted with a filter plate 14 on a carrying plate 13, the filter plate 14 is internally provided with active carbon, so that the formaldehyde and impurities in the air can be well filtered and absorbed, after the formaldehyde is removed for the first time, the air containing the formaldehyde enters a gas storage cavity 21 of a second-stage formaldehyde removing chamber 2 from a second air inlet 15 and is uniformly blown into the second-stage formaldehyde removing chamber 2 from a third air inlet 22, a water suction pump 25 is started, so that a photocatalyst medicament in a liquid storage tank 24 is sucked into the upper part of a flow groove 23 and slowly flows downwards along the flow grooves 23 to form a water curtain, the air containing the formaldehyde entering through the third air inlet 22 is blown against the water curtain to be fully contacted with the photocatalyst medicament, simultaneously, the ultraviolet tube 26 is opened, the ultraviolet rays emitted by the ultraviolet tube 26 react with the photocatalyst medicament to effectively remove formaldehyde in the air, the light-transmitting chamber 27 can allow external sunlight to irradiate, the reaction with the photocatalyst medicament is further promoted, the formaldehyde removing efficiency is improved, the rotating blades 285 on the rotating shaft 283 stir the air in the second-stage formaldehyde removing chamber 2 while rotating, the air flowing speed in the second-stage formaldehyde removing chamber 2 is accelerated, and the formaldehyde-containing air and the photocatalyst medicament react more completely and fully; the air containing formaldehyde after the second formaldehyde removal enters the third-stage formaldehyde removal chamber 3 through the air inlet pipe 31, because the bottom end of the air inlet pipe 31 is inserted into the potassium permanganate solution in the three-stage formaldehyde removing chamber 3, the contact area of the air inlet pipe and the potassium permanganate solution is enlarged, and simultaneously the first motor 32 is started to drive the cam 322 to rotate, because the cross section of the cam 322 is irregular, the cam 322 is matched with the moving block 33, so that the moving block 33 moves up and down periodically when the cam 322 rotates, the second motor 34 is driven to move up and down periodically, and finally the stirring blade 342 on the second motor shaft 341 is driven to rotate and move up and down simultaneously, the air containing formaldehyde in the three-stage formaldehyde removing chamber 3 and the potassium permanganate solution are fully stirred and mixed, so that the formaldehyde removing efficiency is higher, and the air from which the formaldehyde is finally removed is discharged from the air outlet 35.
Carry thing board 13 when using, after active carbon absorption formaldehyde in the filter 14 and impurity reach the saturation, when needing to be changed, only need rotate rotation handle 1303, drive dwang 1302 and rotate, make haulage rope 1309 winding on dwang 1302, spur fixture block 1305 simultaneously and remove to dwang 1302 to break away from in the draw-in groove 1308, take out and carry thing board 13 and accomplish the change to active carbon.
