Embodiment 1

[0030] Such as figure 1 , Load activated carbon particles modified by titanium dioxide in the air purification column, the filling height is 18 cm, and the height of water in the air humidification part is 16 cm, and the water temperature is kept at 60 ° C by heating. In a certain room, the concentration of formaldehyde in the air is 0.55mg / m 3 ;The concentration of ammonia is 0.95mg / m 3 ;The concentration of inhalable particulate matter is 1.95mg / m 3 . After the purification and humidification device was operated indoors for 4.5 hours, the concentration of formaldehyde in the indoor air was 0.05 mg / m 3 , the conversion removal rate is 91%; the concentration of ammonia is 0.01mg / m 3 , the conversion removal rate is 98%; the concentration of inhalable particulate matter is 0.01mg / m 3 , The removal rate is 99.5%.

Embodiment 2

[0032] Such as figure 1 , the air purification column is filled with activated carbon particles modified by activated ferric oxide, the filling height is 16 cm, the height of water in the air humidification part is 14 cm, and the water temperature is kept at 80 ° C by heating. In a certain room, the concentration of formaldehyde in the air is 0.55mg / m 3 ;The concentration of ammonia is 0.95mg / m 3 ;The concentration of inhalable particulate matter is 1.95mg / m 3 . After the purification and humidification device was operated indoors for 5.5 hours, the concentration of formaldehyde in the indoor air was 0.08mg / m 3 , the conversion removal rate is 86%; the concentration of ammonia is 0.05mg / m 3 , the conversion removal rate is 95%; the concentration of inhalable particulate matter is 0.02mg / m 3 , The removal rate is 99%.

Embodiment 3

[0034] Such as figure 2 , the air purification column is filled with vermiculite particles modified by titanium dioxide, the filling height is 16 cm, no water is filled in the air humidification part, and the device only purifies the air. In a room, the concentration of formaldehyde in the air is 0.60mg / m 3 ;The concentration of ammonia is 0.99mg / m 3 ;The concentration of inhalable particulate matter is 2.08mg / m 3 . After the purification device was operated indoors for 6 hours, the concentration of formaldehyde in the indoor air was 0.08 mg / m 3 , the conversion removal rate is 86%; the concentration of ammonia is 0.03mg / m 3 , the conversion removal rate is 97%; the concentration of inhalable particulate matter is 0.05mg / m 3 , The removal rate is 97%.

Abstract

This invention relates to in-house air purification and damping method base on catforming and its equipment. Air is sent into air purification column that filled with chemical modification adsorbent stationary bed by ventilating plant to make poisonous, harmful chemical substance, dust particle and bacteria microorganism to be adsorbed and removed by filtration. Chemical modification adsorbent not only has great adsorbing capability and good filtration, but also can turn adsorptive poisonous matter into nontoxic matter. so it can purify air in-house. Air after purification is delivered to under water level of a sir damping equipment. Then the air is purified further, and the air enters room again with moisture. The in-house air is purified and damped further. In the equipment, air can be heated according to in-house humidity to increase the moisture quantity carried by the air, or the air is not heated and it carry natural moisture after through water to house. Double goals of in-house air purifying and damping is reached by this multifunction setting, so people can enjoy fresh air in closed house.

Description

technical field [0001] The invention relates to an indoor air purification and humidification method and equipment for controlling indoor air pollutants based on a catalytic conversion method, which further improves the indoor air quality while purifying the indoor air and combined with air humidification. Background technique [0002] After experiencing "soot type" and "photochemical smog type" pollution, human society has entered the third pollution period characterized by "indoor air pollution". In recent years, with the development of science and technology and the improvement of people's living standards, a large number of new construction and decoration materials, daily chemicals have entered residential and public buildings, and in order to save energy in modern buildings, buildings are more and more tightly closed, reducing The circulation of indoor air, coupled with the toxic gases released by interior decoration materials, modern office eq...
