Embodiment 1

[0046] The specific operation is as follows:

[0047] 1) Remove the cover plate 44 from the equipment, take out the water tanks 41 on both sides, add 100 mL of formaldehyde-removing active liquid (compound amino acid active liquid, aqueous solution, solid content 9%) to the left water tank, and add 100 mL of purified water to the right;

[0048] 2) Insert the water tank 41 into both sides of the equipment, that is, place it on both ends of the water storage tank;

[0049] 3) Place the wet curtain 43 vertically on the water storage tank, cover the cover plate 44, and wait for 10 minutes to get wet;

[0050] 4) Insert the power cord into the power socket, and place the device in a formaldehyde concentration of 1.012mg / m 3 3m 3 In the environmental chamber, connect the power cord to the power supply, click the power button to turn on the power (the power symbol on the power button is lit at this time), and click the air volume adjustment button to adjust the air volume to the m...

Embodiment 2

[0054] The specific operation is as follows:

[0055] 1) Remove the cover plate 44 from the equipment, take out the water tanks 41 on both sides, pour out the liquid in the two water tanks, and add 100 mL of formaldehyde-removing active liquid (compound amino acid active liquid, aqueous solution, solid content 6%) to both water tanks;

[0056] 2) Remove the remaining liquid in the water storage tank 42, and insert the water tank 41 containing the active liquid into both sides of the equipment, that is, place it on both ends of the water storage tank;

[0057] 3) Take an unused wet curtain 43 and place it vertically on the water storage tank 42, cover it with a cover plate 44, and wait for 10 minutes to get wet;

[0058] 4) Insert the power cord into the power socket, and place the device in a formaldehyde concentration of 1.124mg / m 3 3m 3 In the environmental chamber, connect the power cord to the power supply, click the power button to turn on the power (the power symbol on...

Abstract

The invention discloses a cold volatilization type formaldehyde removal device and a working principle thereof. The device comprises a main shell, wherein a front air outlet module is arranged on thefront face of the main shell; a rear air inlet module is arranged on the back face of the main shell; a moisture absorption and formaldehyde removal module, an electric control module and a fan are arranged in the main shell; and the fan is located on the back of the front air outlet module. According to the working principle, the self-absorption siphon effect of a wet curtain is utilized, a formaldehyde removal active liquid forms a molecular-level dispersion liquid film on the surface of the wet curtain, formaldehyde in air blown through the wet curtain can be rapidly captured and removed, and moisture is volatilized in a cold mode and enters the air for humidification. The device is easy and convenient to assemble, adjustable in air speed, free of consumable consumption and capable of efficiently removing indoor polluting formaldehyde and adjusting space humidity, and a formaldehyde bonded product does not enter air and is safe and reliable; 2400 mg or more of gaseous formaldehyde in the air can be effectively removed by filling a water tank with 100 mL of the active liquid at a time, and the amount is far higher than the accumulated purification amount of 1500 mg prescribed inthe national standard F4 for a household air purifier; and a formaldehyde content can be reduced to 0.02 mg / m<3> or below from 1-1.2 mg / m<3> after the device is tested in an environment cabin with a volume of 3 m<3> for 20 min, and the removal efficiency is higher than 98%.

Description

technical field [0001] The invention relates to the field of indoor air pollution control technology and manufacturing and processing technology, in particular to a cold volatile formaldehyde removal device and its working principle. Background technique [0002] For indoor formaldehyde pollution control, many methods are currently used, such as physical adsorption method, oxidative degradation method, catalytic oxidative degradation method, photocatalytic oxidative degradation method, chemical adsorption method, etc. Among them, the chemical adsorption method has the advantages of large adsorption capacity, strong adsorption with formaldehyde and not easy to desorb, etc., and is currently the most common method for indoor formaldehyde treatment. Formaldehyde chemical adsorbents (also known as formaldehyde capture agents) are often achieved by secondary modification of activated carbon, molecular sieves, porous clay, macroporous silica gel, porous alumina, and directional sy...
