Description
Technical field:
The present invention relates to a kind of environmental protection new product, be specifically related to novel absorption material of a kind of air pollution treatment and preparation method thereof.
Background technology:
Active carbon is well-known traditional sorbing material, the Germany that originates from the World War I, use till today always, both made at recent the war in Iraq, the chemical defence breathing mask that the go-go soldier of army is used, the sorbing material of use remains active carbon, but active carbon does not successfully enter the improvement that vast family carries out room air pollution so far, its reason is many-sided: the one, and active carbon itself is subject to the interference of hydrone and other secondary gas molecule, reduces its activity; The 2nd, active carbon powder or particle easily diffusion pollute; The 3rd, there are not activating process and technology of the package targetedly.Above factor makes the charcoal absorption specific aim not strong, and adsorption effect is undesirable, and utilization rate is low, and service life is short, and practical value is not high, is difficult to satisfy the needs of family's air pollution treatment, can not be accepted by users.Though what have once will use after the active carbon elder generation supercharging moulding reactivation; even but the active carbon after this supercharging moulding activates once more; its active virtual value still is subjected to greater loss; adsorption capacity reduces greatly; cause the waste of active carbon; for this reason; the scientists of some developed countries was once launched deep research with regard to active carbon forming; finally abandon owing to practical function is undesirable; simultaneously; it is harmful and unhelpful that pressed active carbon places indoor for a long time, and the expert confirms, when charcoal absorption poisonous and harmful substances especially gaseous matter reaches capacity state; under the control environment condition, lentamente the poisonous and harmful substances that adsorbs is discharged; be referred to as automatic desorption process, become indoor new pollution sources, this is that environmental protection institute is unallowed.Because traditional active carbon itself does not have degraded and transforms the function of adsorbed material, it is a physical adsorption process, and active carbon all has certain service life.Therefore, this will ask for help have a high regard for science, develop a kind of new product that meets the improvement room air pollution of scientific law, targeted, with practical value, real environment-friendly type practically.
Summary of the invention:
Technical problem to be solved by this invention is:, suction-operated specific aim not high at traditional active carbon utilization rate when being used for treating indoor air pollution is strong, adsorption capacity with the prolongation that stores haulage time weaken, service life is short, be subject to weak points such as hydrone or other secondary gas molecule interference, and novel absorption material of a kind of air pollution treatment and preparation method thereof is provided; Novel absorption material of the present invention is toxic gas such as the formaldehyde in the absorbed air, toluene, dimethylbenzene, sulfur dioxide, nitrogen dioxide, carbon monoxide effectively, and can also effectively suppress and kill airborne virus, germ, acarid etc., the effectively interference of opposing hydrone and other secondary gas molecule, the toxic gas that the digestion degraded is adsorbed is as sulfur dioxide, nitrogen dioxide gas etc.And solved and store the problem that haulage time influence absorption property, novel absorption material function of the present invention is many, has very strong selection adsorption function, effective, and effect is lasting rapidly, uses and handles convenience, and technical performance is good.
The technical solution used in the present invention is: the novel absorption material of this air pollution treatment is made up of active carbon or charcoal and additive, and weight portion is as follows: active carbon or charcoal 50-100, additive 0-50; Additive adopts colloidal silica, calcium hypochlorite, anhydrous cupric sulfate, anhydrous calcium chloride or calcium oxide etc.
Concrete preparation method is:
1. the baking treatment process of heating: get above-mentioned active carbon or handle through grinding, charcoal that specific area is bigger, put into the pot arch baking processing that heats up, sealed environment 200-800 ℃, handled 2-6 hour;
2. detonation treatment process: above-mentioned active carbon or charcoal are sent into the detonation device carry out detonation and handle, in the airtight container, be pressurized to 4-16 atmospheric pressure, instant decompression produces the decompression explosive effect then, but the repeated multiple times processing;
3. vacuum processing technique: above-mentioned active carbon or charcoal sent into carry out application of vacuum in the vacuum storehouse, the decompression of finding time of vavuum pump or additive method, but repeated multiple times is handled;
Above-mentioned reinforcement activating process 1., 2., 3. can adopt wherein any one or two or three whole;
4. above-mentioned active carbon or charcoal and additive is deployed and mix by compositing formula;
5. the above-mentioned active carbon that mixes or charcoal and additive compound are carried out vacuum packet and pretend external packing, the integrated or exterior and interior packing separately-loaded combination of practicable exterior and interior packing.
Substantive distinguishing features of the present invention and remarkable result:
1, product of the present invention is Powdered or granular hybrid solid with certain particle size.Nonhazardous solid additive according to the interpolation of " material composition " prescription, can resist the interference of hydrone and other secondary gas molecule, even air humidity bigger or rugged environment in use and also not influence its effect and life-span, energy suppresses and kills airborne virus, germ, acarid etc., can digest degraded toxic gas such as sulfur dioxide, nitrogen dioxide etc.Handle the interference that to remove other secondary gas molecule with " reinforcement activating process ", get rid of the absorption obstacle, further open sorption channel, thereby make it have very strong absorption specific aim and good adsorptivity, improve the result of use and the utilization rate of active carbon.
2, product of the present invention belongs to not pressed active carbon fitting-type product.Product design is decided by packing.And can utilize packing to reach certain decorative effect.
3, product of the present invention is easy to use, can put, can display, can hang and can glue.Use the back easily to handle.Nonhazardous own does not have noxious material yet and generates after the use, can not cause secondary pollution to air.
4, product of the present invention keeps loose condition (of surface), and charcoal can be done to grind and handle, and not supercharging, not moulding do not use liquid to make additive, is keeping specific area greatly, and suction-operated is rapid, and absorption property is good, the adsorptive value height, and the utilization rate height, practical.
5, product of the present invention adopts vacuum packet to pretend external packing, and storage, transportation do not influence its absorption property.
When 6, product of the present invention is used in treating indoor air pollution, main dusty gas in the room air such as formaldehyde, toluene, dimethylbenzene and sulfur dioxide, nitrogen dioxide, carbon monoxide etc. are had good selection adsorption function, the virus in the room air, germ, acarid etc. are had good restraining and kill function.Be used in others other material is had good selection adsorption effect equally.
