Description
Technical field
The utility model belongs to the air purifying process field, but is specifically related to a kind of filter and air purifier of automatic regeneration filter core.
Background technology
What the filter of employed removal indoor harmful gas mainly adopted in air purifier at present is active carbon filter, active carbon filter is after using a period of time, owing to be adsorbed on the increase of its surperficial pernicious gas, its adsorption capacity descends, thereby cause the clean-up effect of clarifier complete machine to descend, reach after the certain hour, its detergent power can completely lose, and is difficult for regeneration.
NACF claims that also fibrous activated carbon is efficient sorbing material and the environment-friendly engineering material that performance is better than granular activated carbon.It is the active adsorbing material of the third type after Powdered Activated Carbon and granular active carbon, is the renewal product of granular active carbon.The NACF main component is made up of carbon atom.NACF has flourishing specific area and abundant microporous footpath.The specific area of general NACF can reach 1000m2/g-1600m2/g.Both at home and abroad to NACF Products Development and utilization, be primarily aimed at its efficient absorption at present, adsorption capacity is big, and absorption, desorption rate is fast, easily regeneration, and ash content is few, and is acidproof, alkaline-resisting, has excellent conducting performance and chemical stability and waits and carry out.
One, medicine and health aspect
1, the size of virus is about tens nanometers usually, and common cotton cloth respirator only must change with several hours.Therefore, we can become activated carbon fiber cloth the NACF protective mask, and it can also be used for chemical industry material places such as organic gas, agricultural chemicals, acid volatile matter except having gas defence, bacteriological filtration function.
2, NACF be used for medical treatment purify the blood, virus filtration.
Two, military and anti-terrorism field
In order to protect multiple toxic gases such as phosgene, sarin, NACF felt or cloth and the bonding form of base cloth (cotton, colour camoufague cloth etc.) employing can be made one.Keep the high efficiency of additive capability of NACF on the one hand, also strengthened intensity simultaneously.Can make protective clothing, breathing mask, the gas defence cap of protection against chemical poison gas.
Three, water treatment aspect
NACF can successfully be processed into the folding cylindrical filter cartridge of NACF in China at present.The filter core specification is that 250mm-1000mm does not wait, the stainless steel pleated filters of supporting diameter 68mm.Water treatment amount 0.2m3/h-0.8m3/h.Equipment volume has bigger filter area and filter effect than the more miniaturization of other filter plants, also has the ability of the following particle of 5 μ m in the trap water, and filter effect is remarkable.This equipment is used for running water, water for industrial use and industrial pure water as the household tap water water purifier.Utilize NACF to make filter core, can be made into cartridge filter for main material.Can effectively dechlorinate, antibiotic, decontamination, accomplish to purify water-saving.This technology has application corresponding in the NACF field of purifying waste water.As patent publication No.: CN1488432, name is called: a kind of Chinese patent of renovation process of NACF discloses a kind of a kind of renovation process of using NACF with NACF processing industrial wastewater that the present invention relates to.Employing 50～220V voltage is also controlled electric current and is regenerated for 1～2 ampere, utilizes and himself does resistance, makes adsorbed organic matter and stink chemical substance obtain quick desorption and regeneration by current flow heats.In regenerative process, bubbling air or nitrogen can be used for the regeneration of the NACF of various processing industrial wastewaters simultaneously.
Four, household and finishing
At present, in China's building decoration, furniture paint, compoiste wood floor and the adhesive etc. of use all contain VOC (as formaldehyde, toluene), and human body is had very big harm.NACF has good adsorption capacity to microorganism and bacterium, can reach 96%-99% to the bacteriostasis rate of bacterium, and low concentration (PPM level) adsorbate is still had very high adsorbance.We can be according to the height absorption property of NACF to organic gas, and the NACF film of these harm gases can be efficiently adsorbed in exploitation, film is knitted in the mylar again.NACF is higher than active carbon owing to its cost, less employing in air purifier, the at present domestic also not exploitation of this product.
Summary of the invention
The purpose of this utility model is to provide a kind of filter and air purifier, can recover the clean-up effect of clarifier to NACF filter core automatic regeneration; Can make activated carbon fiber filter realize using repeatedly, need not regularly it to be changed.
The utility model is achieved through the following technical solutions:
Filter includes shell, wherein, two electrodes that described filter also comprises the NACF filter core that is arranged in shell inner cavity and is positioned at described NACF filter core two ends, described electrode contacts closely with the NACF filter core; Described electrode is provided with the contact of stretching out described shell.
On the outer surface of described NACF filter core, be provided with temperature sensor.
Air purifier includes body, is positioned at air inlet and the air outlet that is provided with on the described body, the above-mentioned filter that is positioned at described internal body, the ventilation unit that is positioned at described internal body and controller.
Described temperature sensor and controller are electrically connected.
To sum up, the beneficial effects of the utility model are:
Filter of the present utility model and air purifier, two electrodes that comprise the NACF filter core that is arranged in shell inner cavity and be positioned at described NACF filter core two ends, electric current contacts closely between electrode and the NACF, so that can flow through the monoblock NACF equably during electrifying electrodes.NACF itself has certain resistance as a kind of felted thing.In the energising of NACF two ends, can make itself heating, temperature raises, and absorption pernicious gas thereon can come out from its surface desorption, thereby makes regeneration, recovers its adsorption capacity.On the NACF surface temperature sensor is set, links to each other with the controller of clarifier.This active carbon filter is installed in the air purifier, after operation a period of time, it reduces the air cleaning ability at clarifier, and move to clarifier outdoor this moment, by controller electrode is switched on, the active carbon fibre denapon has electric current to flow through therein, so its surface temperature raises, if when the NACF surface temperature surpasses certain value, electrode is cut off the power supply, start the clarifier blower fan, blow away the pernicious gas that desorption goes out, thus the regenerative process of finishing.Can make activated carbon fiber filter realize using repeatedly.Need not regularly it to be changed, can finish regeneration within 10 minutes, recover the clean-up effect of clarifier.
