Embodiment 1

[0032] The components and mass fraction of an oil-in-water VOC absorbent are:

[0033] Tween 5%

[0034] Triisopropylbenzene 25%

[0035] Diethylene glycol butyl ether 70%

[0036] Through the above-mentioned oil-in-water type VOC absorbent, the method for processing VOC in the air, the steps are:

[0037] First add 5 parts by mass of Tween (Tween) into 70 parts by mass of water, shake well, then add 25 parts by mass of triisopropylbenzene into water and mix it into a microemulsion and put it in a sealed container; will contain 1000ppm VOC The air is concentrated into the microemulsion and exits through the outlet pipe, and the outlet gas is purified gas (containing VOC15ppm), which can be directly discharged into the room.

Embodiment 2

[0039] The components and mass fraction of a water-in-oil VOC absorbent are:

[0040] Span 3%

[0041] Biphenyl 22%

[0042] water 75%

[0043] Through the above-mentioned water-in-oil type VOC absorbent, the method for processing VOC in the air, the steps are:

[0044] First add 3 parts by mass of Span to 75 parts by mass of water, shake well, then add 22 parts by mass of biphenyl to water and mix it into a microemulsion, put it in a sealed container; concentrate the air containing VOC Pass into the microemulsion, and pass out through the outlet pipe, the outlet gas is the purified gas, which can be directly discharged into the room.

Embodiment 3

[0046] The components and mass fraction of an oil-in-water VOC absorbent are:

[0047] Polysorbate (Tween) 8%

[0048] Material A 27%

[0049] water 65%

[0050] Wherein, material A is a mixture of eicosane and triisopropylbenzene at a ratio of 1:1.

[0051] Through the above-mentioned oil-in-water type VOC absorbent, the method for processing VOC in the air, the steps are:

[0052] First add 8 parts by mass of polysorbate (Tween) to 65 parts by mass of water, shake well, then add 27 parts by mass of material A into water and mix it into a microemulsion and put it in a sealed container; put the VOC-containing air Concentrate into the microemulsion, and pass out through the outlet pipe, and the outlet gas is the purified gas, which can be directly discharged into the room.

Abstract

The invention provides a VOC absorbent. The VOC absorbent is prepared from 3%-8% of Tween or Span, 20%-30% of a material A and the balance water. The material A is one of or a combination of triisopropylbenzene, biphenyl and high alkane. The invention further provides a processing method of VOC in the air. The method comprises the steps that the components are mixed to form microemulsion, the air containing VOC is introduced into the microemulsion in a concentrated mode and introduced out through an air outlet pipe, and outlet air is purified air which can be directly discharged into the interior. Accordingly, VOC in the air can be effectively removed, the method is simple, and use is convenient.

Description

technical field [0001] The invention relates to indoor air purification, in particular to a VOC absorbent and a VOC treatment method in the air. Background technique [0002] VOC is the English abbreviation of volatile organic compounds (volatile organic compounds). VOC in the general sense is command volatile organic compounds; but the definition in the sense of environmental protection refers to a type of active volatile organic compounds, that is, the type of volatile organic compounds that will cause harm. The main components of VOC are: hydrocarbons, halogenated hydrocarbons, oxygen hydrocarbons and nitrogen hydrocarbons, which include: benzene series, organic chlorides, Freon series, organic ketones, amines, alcohols, ethers, esters, acids and petroleum hydrocarbon compounds Wait. These volatile organic compounds include substances such as toluene, benzene, xylene, formaldehyde, formic acid, ammonia, ethylene glycol, and esters. When the VOC in the room reaches a ce...
