Abstract
A method for removing pollutants from air by use of both streamer discharging and photocatalysis features that under the drive of blower, the air to be treated sequentially through coase net filter, streamer, discharge-photocatalysis reaction segment, and adsorption-catalysis reaction segment to exhaust clean air.
Description
Technical field
The present invention relates to a kind of to the not smooth ground that ventilates, semi-underground and the underground structure is inner; or the method that purifies of the multiple pollutant in the airtight and semi-hermetic cabin air; belong to public health and field of environment protection; be specifically related to a kind ofly utilize filtration, streamer-discahrge, photocatalysis, absorption and the catalytic action multiple pollutant (grit, bacterium, virus, smoke from cigarette, oil smoke, sulfur dioxide, nitrogen oxide, hydrogen sulfide, ammonia, formaldehyde and VOC etc.) in purifying air simultaneously, thereby obtain the method for pure air based on collaborative.
Background technology
Dwelling house, underground parking, civil air defense constructions and installations, underpass, public place and the interior of building that the crowd is dense, and the ambient air quality in the cabin of all kinds of traffic, means of transport and health, life security, physical efficiency performance, and weaponry, instrument and meter performance are closely bound up.Yet because the enclosure effect of construction material or other construction material, it is outdoor or out of my cabin to make the air in indoor or cabin be different from.Nearest one of Environmental Protection Agency studies show that, people in the indoor degree of some pollutant of accepting above outdoor 100 times.A research of Hong Kong environmental administration points out, has 1/3 Indoor Air Quality in Office Building not meet the standard of the World Health Organization and other linked groups approximately.Australian researcher thinks that the pollution level of room air is above outdoor 5 to 20 times.Similarly, some air pollutants airtight or the semi-hermetic cabin also are varied, and concentration is considerably beyond safe range.As in the detected pernicious gas in submarine cabin kind surplus in the of 400 nearly, harm, particularly its accumulation synergy such as these pernicious gases are toxic respectively, excitant and corrosivity can be to the serious disasters of ship person, weaponry even submarine formation itself.By detecting, having determined has the basic chemical substance of 28 classes at the trace contaminant in Russia " peace " number cabin, space station, is divided into aliphatic series and aromatic hydrocarbons, alcohols, aldehydes, ketone, ester class and halo carbohydrate etc.Pollutant is varied in interior of building or the cabin air, complicated component, existing gaseous contaminant, comprise organic compounds such as formaldehyde, benzene,toluene,xylene, styrene, sulfur dioxide, nitrogen oxide, carbon dioxide, hydrogen sulfide, ammonia and so on inorganic compound, and particle, comprise bacterium, smog and dust etc.The purified treatment of pollutant in the air ambient in the indoor or cabin of this class, the more method of research is filtration, absorption, photocatalysis, plasma, negative oxygen ion, biodegradation, ozonization etc. at present, these methods can play the effect of purifying air pollution thing to a certain extent, but all have limitation.Such as, filtration can only be removed thicker particulate matter.Though absorption removes big molecule organic gas efficient height, can not efficiently remove the harmful organic compound of low molecule.In addition, need periodic replacement after also existing absorption saturated, and easily stopped up, may become the hotbed of harmful bacteria procreation, cause more serious secondary pollution problems by particle.Photocatalysis is a domestic and international research focus in recent years, strong oxidizing property materials such as hydroxyl radical free radical by the photocatalysis generation, can effectively decompose partial organic substances and kill bacteria, virus, but when handling the common organic matter of benzene,toluene,xylene and so on interior of building or cabin environment, activity descends rapidly.Plasma technique is by high energy electron, and excites the oxidative free radical of generation to open the chemical bond of pernicious gas molecule thus, realizes the purification of pollutant, can act on multiple polluter.But, when producing plasma, generate a large amount of ozone usually.Although ozone also has very strong oxidation Decomposition organic pollution and sterilization ability, also often cause the ozone severe overweight.Other method also all exists similarly not enough.
Summary of the invention
There is limitation separately in order to overcome the existing method that pollutant in the environment is carried out purified treatment, maybe can not purify multiple air pollutants, maybe can produce the deficiency of secondary pollution, the objective of the invention is to propose a kind of multiple pollutant coexistence system in interior of building or the cabin to be carried out air purification method.More particularly, be on the basis of main air pollutants type and the approach of purification thereof in analyzing interior of building or cabin, propose to work in coordination with and utilize filtration, streamer-discahrge, photocatalysis, absorption and catalytic action to realize the purification of multiple air pollutants, and do not produce the method for secondary pollution.
The technical solution adopted for the present invention to solve the technical problems is as follows:
A kind of collaborative method of utilizing streamer-discahrge, photocatalysis, filtration, absorption and catalytic action purifying air pollution thing, this method makes pending air successively by exporting pure air after coarse strainer, streamer-discahrge-light-catalyzed reaction section, the absorption-catalyst reaction section by blower fan power, and the step of this method is:
(1) pending air separates the airborne thicker particle of removal by coarse strainer under the effect of blower fan draft;
(2) by being applied between receiving electrode and the discharge electrode, high voltage produces streamer-discahrge, with the gaseous contaminant of action of plasma after handling that streamer-discahrge produces, the intermediate product that makes the part gaseous contaminant be converted into harmless product or need further to handle through step (1);
(3) effect of the high voltage field by the streamer-discahrge conversion zone deposits on earthing pole and the discharge electrode particle of not separating from air-flow after step (1) is handled;
(4) time of sending by streamer-discahrge, the catalysis material that applies in conjunction with earthing pole when carrying out step (2), (3) carries out light catalytic purifying to the gaseous contaminant after handling through step (1), and sterilization;
(5) by material removal coarse filtration that has absorption and catalytic action concurrently and the pollutant that streamer-discahrge-the light-catalyzed reaction section does not purify, and the ozone of streamer-discahrge-light-catalyzed reaction section generation, the output pure air.
The invention has the beneficial effects as follows:
1, the inventive method makes pending air successively by coarse strainer, streamer-discahrge-light-catalyzed reaction section, absorption-catalyst reaction section by blower fan power, by the coordination utilization of filtration, streamer-discahrge, photocatalysis, absorption and catalytic action, make and to realize that in the cleaning system of a compactness particle (comprising bacterium, virus, smog etc.) separates or purification with the efficient of multiple gaseous contaminant;
2, the active particle that produces of streamer-discahrge or directly decomposing pollutant, or with the polluter adsorption and enrichment on absorption/catalysis material surface, strengthened catalyticing decomposition action, improved purification efficiency;
3, the time of utilizing streamer-discahrge to produce is made the required light source of photocatalysis, and special light-catalyzed reaction light source need be set;
4, absorption/catalysis material is not only effective to the pollutant decomposing, purifying, and harmful side product such as enrichment, ozone decomposition effectively, guarantees not produce secondary pollution;
5,, make that absorption effective acting time of sorbing material is much longer when lacking above-mentioned effect because filtration, streamer-discahrge, photocatalysis and catalytic action.
