Test data:
Test method: in the big room closed, room area 300 square metres, different air purifiers is set, different
The difference of air purifier be: screen plate used is different.The filtering material that air purifier is used is institute of the present invention
The material prepared, without other materials, such as: Linesless charcoal.
Detecting instrument is: trade name: Bramc air quality detector, model: BR-HOL-1210.
Before air purifier work, the mean concentration of detection room air pm2.5 is 172 microgram every cubic metre.
Air purifier works latter 30 seconds, at air vent detection air after filtering.
Same steps prepare screen plate, manufacture 3 pieces, then, make 3 air purifiers.Each filter test 3
Secondary, take 9 times after filtering the meansigma methods of measured value as the filter effect value of this screen plate (or filter).
This specification relates to these words: the collocation method of described " oxalic acid and the mixed solution of sulphuric acid ": the first step, join
Putting the careless aqueous acid that mass percent concentration is 6.7%, second step, configuration quality percent concentration is the sulphuric acid of 4%
Aqueous solution, the 3rd step, the oxalic acid solution of mixing first step configuration and the sulfuric acid solution of second step configuration.
Inventor finds, in the 3rd step described in the preceding paragraph, oxalic acid solution, the quality proportioning of sulfuric acid solution, be to affect
The key factor of filter effect.
Order: concentration be the careless aqueous acid mass parts of 6.7% be 200；The sulphuric acid that packet adds different quality part is water-soluble
Liquid, the mass parts of addition is respectively as follows: 0,5,10,15,20,25,30,35,40,45,50,55,60,65,70,75,80,85,90,
95、100。
The test data of embodiment one, two is as shown in Figure 1 and Figure 2.
In figure:
The meaning of transverse axis is: the mass fraction of sulfuric acid solution.
The meaning of the longitudinal axis is: the pm2.5 concentration of filtered air, unit: microgram every cubic metre.
Showing in figure: in special value interval, the addition of sulfuric acid solution significantly have impact on final filtration effect
Really.Concentration be the careless aqueous acid mass parts of 6.7% be 200, mass percent concentration is the matter of the sulfur aqueous acid of 4%
When amount part is 50,55,60, filter effect is preferable, and the air pm2.5 concentration after filtration is less than 25 microgram every cubic metre, especially
Mass percent concentration is the mass parts of the sulfur aqueous acid of 4% when being 55, and filter effect is optimal.
Test is also found that embodiment one, two to be affected little on the gas flow of air purifier.Gas flow is 196-
209 cubic metres per hour.
The present invention first penetrates into calcium hydroxide in timber, then, the slow effect of the carbon dioxide in air, become
For the hardest limestone, then, carry out attacking limestone with acid, and discharge carbon dioxide, through the erosion of alkali liquor, then
Plus the spilling of carbon dioxide, plank becomes the material of porous, and becomes the material that may filter that gas.Select oxalic acid and sulfur
The solid matter that acid obtains has the advantage that soft or hard is suitable, pore is little and intensive.
In terms of the selection of acid: test also finds, do not reach such effect with hydrochloric acid, use hydrochloric acid, not only cross air filtration
The efficiency of body is low (flow 140-152 cubic meter is per hour), and, the air after filtration, the concentration value of its pm2.5 is the biggest: 46-
82 micrograms every cubic metre.Test also find, only with sulphuric acid also cannot, only with sulphuric acid as select processed with acid must filter
Plate, after one month, filter effect is the worst: filter the efficiency low (flow 103-121 cubic meter is per hour) of gas, and,
Air after filtration, the concentration value of its pm2.5 is the biggest: 84-105 microgram every cubic metre.Only with oxalic acid, in freshly prepared mistake
In filter, filter effect still can, but, after one month, capacity greatly reduces: flow 94-118 cubic meter is per hour.
Test finds, the acid solution used, preferable by the mixed acid effect of oxalic acid and sulphuric acid, and inventor have found suitable
The proportioning closed.
Under normal circumstances, it is believed that the sulfuric acid amount of addition is the most, acidity is the strongest, then, and the plate after calcium carbonate reaction
Material effect should be dull change or simple transformation relation.But, it is a discovery of the invention that special value when,
The filter effect of sheet material there occurs the mixed acid selection acid as the present invention of sudden change, oxalic acid and sulphuric acid, its screen plate prepared
Capacity is big, good filtration effect, and such good effect duration was up to three months.
