Brief description of the drawings
In order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, before creative labor is not paid
Put, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Wherein：1st, reaction warehouse, 2, quartz burner, 3, tail gas recycle storehouse, 4, NACF, 5, activated carbon granule, 6,
Air blower.
Specific embodiment
Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described,
Obviously, described embodiment is only a part of embodiment of the utility model, rather than whole embodiments.Based on this practicality
Embodiment in new, the every other reality that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example is applied, the scope of the utility model protection is belonged to.
According to Fig. 1, the equipment as a kind of new removing Formaldehyde and benzene shown in embodiment includes the reaction of tubular
Storehouse, is provided with quartz burner in reaction warehouse, quartz burner is located on the center line of reaction warehouse, and the madial wall of reaction warehouse is fixed with
Layer of active carbon fiber cloth, is attached with titanium dioxide powder on active carbon fiber fabrics, air blower is provided with below reaction warehouse, reaction
A tail gas recycle storehouse is provided between storehouse and air blower, multilayer activated carbon granule is provided with tail gas recycle storehouse.
Tail gas recycle storehouse is cylindrical shape in present embodiment, and consistent with the diameter of reaction warehouse, air blower for direct current from
Heart air blower, the bottom in tail gas recycle storehouse is connected with the air inlet of air blower.It is provided with horizontally disposed many in tail gas recycle storehouse
Filled with the activated carbon granule by modification in individual interlayer (not shown), interlayer, interlayer is by circular wire netting
Separate.Interlayer is three layers in present embodiment because always the activated carbon granule of the superiors first reacts failure, replacing when
Time first changes the activated carbon granule of layer, and the time of the activated carbon granule of lower floor can so make full use of and save more long
Save activated carbon granule.
Feature of the present utility model is to set up a photocatalyst reaction storehouse, attachment activity Carbon fibe on reaction warehouse surrounding bulkhead
Cloth (plays carrier function), and appendix nano level titanium dioxide powder on active carbon fiber fabrics, and there is quartz burner at reaction warehouse center,
After the formaldehyde of higher concentration, toluene gas enter reaction warehouse in air, under ultraviolet lamp irradiation, appendix on active carbon fiber fabrics
Nano level titanium dioxide can make the oxygen and hydrone of surrounding be excited into active hydroxyl free radical, these free radicals
Almost separable solution formaldehyde, toluene molecule ultimately produces carbon dioxide and water, and titanium dioxide does not participate in reaction, experimental data in itself
Prove, reaction warehouse to the formaldehyde of higher concentration in air, toluene gas removal effect substantially, but to the first of low concentration in air
Aldehyde, benzene, toluene gas scavenging action is limited, and concentration is less than 0.3ppm substantially without elimination effect.
Core of the present utility model is that tail gas recycle storehouse is increased behind reaction warehouse, and recovery bin the inside is filled with column
Modified activated carbon granule, these activated carbon granules are soaked with strong oxidizer, then take out these activated carbon granules then
It is positioned over 110 DEG C of oven dryings 24 hours, increases by the quantity of the activated carbon granule surface oxygen-containing functional group after modification,
Advantageously in the absorption of Formaldehyde and benzene molecule.In the presence of direct current centrifugal blower, air is forced to flow through photocatalyst reaction
Storehouse, most of formaldehyde, toluene molecule are catalytically oxidized to carbon dioxide and water in reaction warehouse in air, remaining few in air
Number formaldehyde, toluene molecule is by tail gas recycle storehouse, low concentration in the modified activated carbon particle energy fully capture air in recovery bin
Formaldehyde, toluene molecule, by so treatment, can reach substantially remove air in low concentration formaldehyde, toluene gas effect,
Experiment proves that formaldehyde in air toluene concentration can be less than 0.05ppm after removing.
If being only not added with tail gas recycle storehouse using photocatalyst reaction storehouse, here it is common photocatalyst catalytic reaction mode, nothing
Method accomplishes effectively removing to the volatile organic matter that low concentration formaldehyde, toluene etc. in air are harmful to.
If only not increasing photocatalyst reaction storehouse above using tail gas recycle storehouse, here it is common charcoal absorption side
Formula, with adsorption saturation degree and secondary pollution, harmful volatile organic matter such as formaldehyde, toluene of high concentration can quickly make work
Property charcoal reaches adsorption saturation, so service life is not long.
Using photocatalyst reaction storehouse and tail gas recycle storehouse compound use, photocatalyst reaction storehouse first removes most of in air
Harmful volatile organic matter such as formaldehyde, toluene, so that efficient, the cleaning, without secondary dirt of photocatalyst catalytic reaction mode
Dye, without adsorption saturation degree, the advantage of long service life is not fully exerted.Through the air after the catalytic reaction of photocatalyst reaction storehouse,
Harmful volatile organic content such as formaldehyde, toluene is very low, through the modified activated carbon particle disposal in tail gas recycle storehouse
Afterwards, harmful volatile organic matter such as the formaldehyde of low concentration, toluene is removed totally substantially in air, and this has given full play to activity
The adsorption function of charcoal, due to being the absorption of low concentration, so considerably increasing the time of adsorption saturation, increases the service life.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any one skilled in the art can readily occur in change in the technical scope that the utility model is disclosed
Or replace, should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should be described with power
The protection domain that profit is required is defined.
