Abstract

The invention relates to a multifunctional efficient air purifying agent and a using method thereof, and belongs to the technical field of indoor air purification and treatment. The multifunctional efficient air purifying agent is made of food grade raw materials in a compound mode and composed of water, a bactericide, a formaldehyde-removing agent, a catalyst, TVOC dissolving agent and a stabilization dispersing agent. The using method of the multifunctional efficient air purifying agent comprises the steps that the purifying agent is sprayed on a rotating wheel film forming device through a feeding box to form a liquid film, and polluted air is sucked by a fan to pass through the liquid film to be purified. The multifunctional efficient air purifying agent is non-toxic and innocuous and has the effects of rapidly removing bacteria, removing formaldehyde, lowering PM2.5 and TVOC and the like in a long-acting mode. The using method overcomes adverse effects caused by direct contact when an air purifying agent is sprayed in air traditionally. According to the using method, the air purifying agent is detected in a 30 m<3> standard experimental cabin, and the formaldehyde removing rate, the bacteria removing rate, the PM2.5 removing rate and the TVOC removing rate within one hour can be higher than 95%.

Description

technical field [0001] The invention relates to a multifunctional high-efficiency air purifier and a method for using the same, belonging to the technical field of indoor air purification and treatment. technical background [0002] With the rapid development of the national economy and the gradual improvement of people's material living standards, people's requirements for home comfort are also increasing. At the same time, with the decline of outdoor air quality and the increasing popularity of indoor decoration, indoor air pollution caused by improper use of decoration consumables and outdoor smog is becoming more and more serious. Among them, the most notable problems are indoor formaldehyde (HCHO) and TVOC release exceeding environmental standards, PM2.5 and bacteria and viruses exceed the standard, etc. my country's "Indoor Air Quality Standard" (GB / T 18883-2002) promulgated in 2002 has made strict regulations on the amount of formaldehyde in indoor air, PM10, bacteri...
