Fig. 2 is the formaldehyde equilibrium adsorption capacity of three groups of mixed adsorbents.
detailed description of the invention:
In order to understand the present invention better, below in conjunction with drawings and Examples, the present invention is further illustrated, but be not intended to limit the present invention.
As shown in Figure 1, a kind of Vehicular formaldehyde clarifier, comprise body 10 and filter, described filter is made up of nylon net filter device 33, graininess cocoanut active charcoal and fragrance releasing shitosan immobilized beta-schardinger dextrin-formaldehyde adsorbent mixing and absorption layer 32, HEPA filter course 31 and photocatalyst purification layer 30 from top to bottom.The bottom of body 10 is provided with base, is provided with ultraviolet lamp, anion generator, ozone generator and blower fan in body 10; Also intelligent chip is provided with in body 10; The shell of body is provided with display screen and switch key.Body both sides are provided with air outlet 11, and organism top case 40 is metallic screen net type air inlet, and filter is located at below air inlet.Body 10 is also provided with champignon cotton hole slot, cigarette lighter power line and remote control.Described graininess cocoanut active charcoal and fragrance releasing shitosan immobilized beta-schardinger dextrin-formaldehyde adsorbent mixing and absorption layer are a kind of double-layer filter structures, two-layerly up and down be non-woven fabrics filter screen, be adopt paper material to be separated into some cellular spaces between two-layer nonwoven filter screen, in space, be filled with graininess cocoanut active charcoal and the immobilized beta-schardinger dextrin-formaldehyde adsorbent of fragrance releasing shitosan.
After cigarette lighter power line (jack is positioned at body 10 lower left) accesses vehicle power, can the manual operation switch button positive side display screen of body 10 (be positioned on the right of), or by the operation of remote controller remote-controlled machine in 5m, but when upper cover 40 has not fastened, machine can automatically detect abnormal by intelligent chip and can not start.When machine runs, from upper cover 40 air intake, air-flow is according to this by nylon net filter device 33, graininess cocoanut active charcoal and fragrance releasing shitosan immobilized beta-schardinger dextrin-formaldehyde adsorbent mixing and absorption layer 32, HEPA filter course 31 and photocatalyst purification layer 30, from body both sides 11 air-out, blower fan has two grades of wind speed can select according to in-car air quality situation.For the ease of energy-conservation, air-out is utilized to bring out fragrance from graininess cocoanut active charcoal and fragrance releasing shitosan immobilized beta-schardinger dextrin-formaldehyde adsorbent mixing and absorption layer 32 and champignon sponge 21 (dropping essential oil); Simultaneously ozone function has independent switch control rule, can select when in car nobody time open, avoid ozone to work the mischief to human body; Intelligent chip technology achieves timed power on/off, and automatic shutdown after operating 2 hours, has hommization, energy-conservation feature.
Use dynamic experiment method, the present invention has investigated the absorption property of mixed adsorbent PARA FORMALDEHYDE PRILLS(91,95).At ambient temperature, be respectively 2:1,1:1,1:2 by graininess cocoanut active charcoal and fragrance releasing shitosan immobilized beta-schardinger dextrin-formaldehyde adsorbent mass ratio and take 0.5g mixed adsorbent, divide three groups and put into the adsorption column that internal diameter is 7mm, using air as carrier, formaldehyde is passed into by Bubbling method to mixed adsorbent bed, by formaldehyde absorbing breakthrough curve reflection formaldehyde absorbing situation under air mass flow is 30ml/min.As shown in Figure 2, the mixed adsorbent PARA FORMALDEHYDE PRILLS(91,95) that result shows these three ratios all has good adsorption effect, and when the mass ratio of graininess cocoanut active charcoal and fragrance releasing shitosan immobilized beta-schardinger dextrin-formaldehyde adsorbent is 1:1, the equilibrium adsorption capacity of formaldehyde is the highest.
