Description

A kind of method of purification treatment room air
Technical field
The present invention relates to a kind of method of comprehensive purification treatment room air.
Technical background
As everyone knows, after new room finishing, the harmful substances such as the formaldehyde slowly released from finishing material, benzene, dimethylbenzene and ammonia often make room air pollution exceed standard.
1. finishing harm
The time of the mankind 90%, finishing pollution became the killer of 21 century human health in office work and life.The common indoor air pollutants because of finishing generation has: formaldehyde, benzene, ammonia radon and stone material radioactive pollutant etc.And ubiquity and with serious pollution, be formaldehyde and benzene.Benzene and benzene homologues can discharge (generally at 6 to 12 months) in the short period of time, and the impact of formaldehyde is long-term (being 3 to 15 years according to the study).So formaldehyde is one of major pollutants in fitment process.
2. the ubiquitous pollution of finishing material used at present
Finishing causes the formaldehyde in room air mainly to come from the artificial board of finishing material and the use of new composite furniture, as the brill mixture in glued board, lumber core, MDF, wound card (flakeboard), and the chemical building material construction material product such as coating, adhesive, inorganic agent.Content of formaldehyde meets the multiple building materials of national standard scope, furniture and uses the same space is cumulative, is also the reason causing indoor pollution to exceed standard.But state's interior decoration inevitably uses the material containing formaldehyde.Because formaldehyde to be a kind of effect better, the binder that cost is not high, also can not find now a kind of pollution-free, bonding effect good and production cost meets the substituting product of the level of consumption.
3. current decoration company changes pernicious gas and to exceed standard way and deficiency
One is that decoration construction aspect is not comprehensively with careful.Such as when spraying drawer or cabinet is darker, should disassemble, until each can touch aerosolized medication completely, the especially cross section of sheet material, medicament also along otch infiltration, suitably will increase dosing as far as possible.Adjustment in addition for indoor temperature is also very important.
Two is on choice for use photocatalyst material on photocatalyst.Photocatalyst oxidability is in the market poor, causes that air purification efficiency is very slow and effect is general.
4. the main method of the at present purification of room air and deficiency
People take following several method to remove pernicious gas under normal circumstances:
(1) forced ventilation is added: this is a kind of commonsense method.But the harmful substance such as formaldehyde, benzene is concealed in furniture, materials for wall depths, release period 3-15, cannot remove in a short time, once run into the situation using heating installation or air-conditioning etc. to window, indoor harmful gas concentration can rise rapidly, causes long-term hazards to the health of kinsfolk.
(2) plant null method: adopt the flowers such as bracketplant, aloe, sansevieria trifasciata to absorb indoor polluted gas, but plant adsorption effect is very limited, can not reach and purify object completely, and daytime carries out photosynthesis absorbing carbon dioxide, releasing oxygen, night then absorbs oxygen, release of carbon dioxide, unfavorable to human body, particularly to pollen, the easy allergy sufferers of flowers.
(3) chemical reagent sprays: as with chemical agents such as chemical formaldehyde scavenger, air fresheners, can not process clean, be that a kind of gas suppresses another kind of gas, do not reach the object removing pollution sources, and use chemical reagent easily to produce secondary pollution, unfavorable to health.
(4) active carbon adsorption and air purifier: formaldehyde molecule is adsorbed in its inner wall surface by physisorption by active carbon, reach the object of the content of formaldehyde reduced in air, but limited sorption capacity, easily saturated, within about 3-5 month, be difficult to reuse; And active carbon is the formaldehyde absorbing in Nei little space, room therein, external condition also can discharge after changing, and does not reach environmental requirement.Air purifier has certain suction-operated to polluters such as indoor formaldehydes, and it is better that effect generally understands specific activity charcoal, can remove pernicious gas and the dispelling abnormal flavors such as indoor formaldehyde, radon gas, benzene, ammonia, TVOC.But can not very process clean at short notice, clarifier price is relatively high, different product is also different for service life, and clarifier can not pollution administration source, act on by its technology adopted larger with the position limitation put, if so a clarifier is only put in a cover house, often only have certain effect to the room that clarifier is placed, and less to the effect in other rooms.
Summary of the invention
In view of this, for overcoming above-mentioned the deficiencies in the prior art, the object of the invention is a kind of method providing purification treatment room air, it is characterized in that, comprises improvement work progress, described improvement work progress following steps:
A. the surface cleaning of indoor base material (furniture, door and window, floor, wall, cloth art etc.) is carried out;
B. to indoor household electrical appliances, electronic instrument shutdown closed protective, close the doors and windows;
C. temperature debugging is carried out to scene: during low temperature, 20 DEG C should be not less than, 32 DEG C should be no more than during high temperature and be advisable;
D. by air compressor and special atomizing lance, by the surface of formaldehyde scavenger atomizing spraying at the sheet material such as furniture, floor, not in place disassembling is sprayed more deeply for drawer or cabinet, until each can touch aerosolized medication completely, repeat to spray once again after first time has sprayed 2 hours;
E. last layer photochemical catalyst is coated with on surfaces such as wall, ceiling, curtain;
F. close the doors and windows three days, make medicament fully permeate and react;
G. to window after three days ventilation, indoor without pollution sources, reach the object of purification treatment room air.
Present invention also offers a kind of photochemical catalyst and collocation method thereof, it is characterized in that, described photochemical catalyst comprises carrier water, alcoholic solvent, oxidation center elemental silver, electronics accommodation element titanium, Ga Element and antimony, reduction elements palladium, active oxide lithium, reducing activity agent zirconium, electro transfer element indium, each group is by weight percentage, carrier water 50-70%, alcoholic solvent 10-15%, titanium 10-20%, silver 1.5-2%, palladium 1.5-20%, antimony 2-3%, zirconium 0.5-1%, indium 0.5-1%, lithium 2-3%, gallium 2-3%.
Its collocation method is, by described metal material element and semi-conducting material, and the form of slaine flows in solvent and carrier water, produces by nanometer materials aqua-solution method, thus obtains nano-scale photocatalyst.
Particularly photochemical catalyst is photocatalyst.
The invention has the beneficial effects as follows:
The present invention is used for the method for purification treatment room air, can reach comprehensively careful to purify room air, present invention also offers a kind of photochemical catalyst and preparation method in addition, by using this photochemical catalyst, its oxidability can be improved, thus improve the efficiency and effect that purify air.
