Description
Technical field
The present invention relates to technical field of air purification, a kind of novel photocatalysis air purifier and the method purifying air.
Background technology
Along with economic growth and social progress, problem of environmental pollution is the most serious.Volatile organic contaminant (Volatile
Organic compounds, VOCs) it is the major pollutants in air, its source part is from outdoor, the most industrial
Waste gas, motor-vehicle tail-gas, photochemical fog etc.；Another part is from indoor, and finishing, ornament materials are as painted and solvent, wood
The multiple volatile organic matter such as toluene, formaldehyde is releasably gone out under the room temperature such as material preservative, coating, plywood.Due to indoor ring
In border, air flow property is poor, and the pollutant of accumulation cause serious harm by breathing and the skin of people to human body.With formaldehyde it is
Example, human body leaks in concentration the most cruelly more than 0.1 mg/m3Formaldehyde atmosphere in, will dizzy, audiovisual retardance, can be right time serious
Respiratory system, cardiovascular and cerebrovascular vessel etc. damage.Multiple VOCs is mixed and mutual chemical action, and harm also can be made strong
Degree increases.Therefore, IAQ (indoor air quality) is improved by purification techniques healthy significant to people.
For VOCs purify technology mainly include adsorption filtration technology, condensation technology, combustion technology, membrane separation technique,
