Abstract
The utility model is related to a kind of air purifier for removing indoor VOCs and preparation method thereof, belongs to technical field of air purification, more particularly to a kind of VUV photocatalysis air purifying device.Air purifier of the present utility model includes drain pan, photocatalytic degradation unit, ozone decomposed clean unit, fan, top shell, shell body.The utility model can continue at room temperature, VOCs rapidly in degraded room air, purification secondary pollutant and unnecessary ozone, and simple in construction simultaneously, it is easily manufactured, more healthy living environment can be provided for indoor occupant, the development for photocatalysis air purifying device is significant.
Description
Technical field
The utility model is related to technical field of air purification, more particularly to a kind of VUV photocatalysis air purifying device.
Background technology
In recent years, the control of environmental pollution and improvement are that human society faces and key subjects urgently to be resolved hurrily, people couple
The understanding of environmental protection extends to interior by outdoor.Waving for interior is discharged into from gasoline, construction material, furniture, cigarette, electrical equipment etc.
Hair property organic chemicals (VOCs) kind up to more than 300, including formaldehyde, benzene homologues, ammonia, dichloro (trichlorine) ethene, an oxygen
Change high-risk, the high toxic gas such as carbon, nitrogen dioxide, sulfur dioxide.These chemical substances can trigger human and animal's body machine
The dysfunction of energy, long-term suction even can be with diseases such as leukemogenesis, cancers.In face of the severe shape of room air pollution
Gesture, people are in the urgent need to seeking a kind of economical and effective and environment-friendly processing method.
The purification style of room air is divided into natural purification method and forces the method for purification.Self-purification is exactly by leading to naturally
Wind, windowing ventilation or installation ventilating fan, indoor contaminated air, the lighter field of suitable pollutant are replaced with fresh air
Close, while the effect of self-purification depends on the clean-up performance of outdoor environment.It is then to use certain technology or skill to force purification
Art product makes the quality of room air take a turn for the better, be particularly suitable for use in room and office space etc. with sealing and pollutant be difficult to
The situation of outdoor diffusion.
Purification is forced to be divided into absorption method and decomposition method two ways again.Absorption method is the conventional process side of room air
Method, generally using either physically or chemically air pollutants are collected, such as mechanical filter formula, absorption type, electrostatic, negative
Oxonium ion air purifier etc..Such method is preferable for the removal effect of solid grain contamination, has the disadvantage dirty for gaseous state
Contaminate thing particularly VOCs removal effect poor.For adsorption cleaning device, over time, sorbing material is up to
Saturation, when temperature, wind speed are increased to a certain degree, the pollutant adsorbed is possible to separate out, is again introduced into
Among room air, it is therefore desirable to which timing updates.
Decomposition method is that gaseous contaminant is degraded by chemically reacting, and eventually becomes harmless material, such as light
Catalytic air purifier, ozone air purifier and bioanalysis air purifier, wherein photocatalysis technology are used as a kind of Novel oxygen
Change technology is increasingly subject to the concern of domestic and foreign scholars.There is researcher to investigate nano-TiO within 20032The photocatalysis performance of coating with
And performance (the HVAC 2002,32,23-25 of several photocatalysis air purifying devices of commercial type；Beijing University of Technology is learned
Report 2005,31,58-62), find TiO2Particle have to indoor air pollutants such as nitrogen dioxide, sulfur dioxide and formaldehyde compared with
Degradation effect well simultaneously lists some technical problems present in several photocatalysis air purifying devices, such as nanomaterial loadings
Not enough firmly or almost do not play a role, its research provides base for the development of photocatalysis air purifying device from now on
Plinth.2007, researcher was by WO3Modified P25 is carried on honeycomb aluminum (Indoor Air 2007,17,305-316), in UVC
Photocatalytic degradation low concentration VOCs obtains good degradation effect under (254nm) light, but the too high cost of energy consumption is high.There is report within 2013
Road is by TiO2(Journal of Hazardous Materials 2013,261,130-138) is supported on carbon fabric fiber,
The light catalytic purifying room air under vacuum-ultraviolet light, the relatively low degradation efficiency of energy consumption is higher, but which presence can not be effective
Remove the excessive ozone produced and form pollution.2014, Pd was carried on TiO by researcher2On film, vacuum is purple at room temperature
Outer Photocatalytic Degradation of Toluene and ozone obtain good removal effect (Chemical Engineering Journal 2014,
252,337-345), but this method introduce precious metals pd, improve prepare cost be not easy to practical application.
In summary, indoor air cleaner or a new and old technology and the field deposited is also one rising
Field.Nowadays, various indoor air cleaners emerge in an endless stream, but all less desirable for clean-up effect.It must integrate
The advantage of various cleaning principles, improves its performance, designs the indoor air cleaner of comprehensive stronger multiple purifying effect,
Indoor air quality could thoroughly be improved.
