Abstract
The invention discloses a method for purifying indoor air by means of a domestic heating radiator. A first adsorption component, a catalytic component and a second adsorption component are sequentially arranged at the upper portion and/or the side portion of the heating radiator. According to the method, the existing heating radiator is used as a power source and a heat source, the cost for adding a power source and a heat source is saved, and the space is saved.
Description
Technical field
The present invention relates to technical field of air purification, be specifically related to a kind of method utilizing household central heating sheet to purify the air of a room.
Background technology
Haze weather is a kind of atmosphere pollution state, haze is the general statement to suspended particulate substance content overproof various in air, and especially PM2.5 (equivalent aerodynamic diameter is less than or equal to the particle of 2.5 microns) is considered to " arch-criminal " that cause haze weather.Sulfur dioxide, nitrogen oxide and pellet are the main compositions of haze.
In early or mid November, 2015, the city being representative with Shenyang and other places, its haze PM2.5 index reaches surprising 1140, belongs to serious pollution.Under this kind of environment, pollutant not only injures the respiratory system of people, and the organs such as eyes also can be caused to produce burning sensation, the health of damage eyes.
For indoor environment, owing to must carry out ventilation with outdoor, therefore indoor air faces the problem that PM2.5 pollutes equally.Meanwhile, along with the raising of people's living standard, the interpolation of interior decoration, new furniture also significantly increases.But in interior decoration and furniture, inevitably use various glue or paint, thus cause distributing various organic pollution to indoor, the such as material such as formaldehyde, benzene.
At present, for the process of these indoor pollutants, be mostly to adopt various air purifier and charcoal absorption etc., but the increase of these equipment, careat can be taken, increase cost.
Summary of the invention
The object of the invention is to propose a kind of method utilizing household central heating sheet to purify the air of a room, its inventive point is just to utilize radiator, and when heating, the flowing of distribute heat and then formation air, it can be used as power source; Meanwhile, because the operating temperature of radiator is between 30-80 DEG C, it contributes to as thermal source the catalytic efficiency improving catalyst.That is, the present invention adopts indoor heating radiator, it can be used as power source and thermal source to use, realizes the catalytic purification of room air.
For reaching this object, the present invention by the following technical solutions:
Utilize the method that household central heating sheet purifies the air of a room, its above radiator and/or side be sequentially set with the first adsorption element, catalytic member and the second adsorption element.
Described first adsorption element is provided with fibrous filter layer, and described fibrous filter layer is superimposed with paper fiber thing filter course and ultra-fine fibre glass thing filter course.
Described catalytic member is provided with catalyst layer, and described catalyst comprises following component,
A) 9% molybdenum, zirconium, vanadium and tungsten composite oxides, its mol ratio is 1:1:1:1;
B) 6% silver and anatase titanium dioxide, the mol ratio of Ag and Ti is 2:5;
C) ZSM-5 molecular sieve of surplus.
Described second adsorption element is provided with adsorption layer, and described adsorption layer is made up of the nano titanium oxide of active carbon and Ag-bearing, and its mixing quality such as, than being 5:1-2:1,4.5:1,4:1,3.5:1,3:1 etc.
The method course of work of the present invention is as follows, and the temperature of radiator is higher than indoor temperature, and air contacts with radiator, be heated backward upper direction, thus produce pressure differential, and then the guiding cool air of bottom contacted with radiator, thus form the flowing of air, air is heated.First the hot-air moved upward enters the first adsorption element, in the first adsorption element, air is successively through paper fiber layer and ultra-fine fibre glass layer, and because described fibrage has tiny space, therefore it retains filtration to the particle in air and macromolecular substances.
Air after filtering enters catalytic member subsequently, in catalytic member, pollutant in air, such as formaldehyde, methacrylaldehyde, toluene, nitrogen oxide and oxysulfide etc., contact with catalyst, because described air is the air of heating, therefore now the activity of catalyst is higher, oxygen generation catalytic oxidation in itself and air, becomes harmless or is easy to other organic matters of absorbing, such as oxycarbide, be easy to the SO absorbing process
2and NO
2.
Air after catalysis, enters the second adsorption element.In air, the organic pollution of catalyzed oxidation is absorbed by active carbon, and is distributed in the silver in active carbon, kills virus to the microorganism in air, thus reduces
Method of the present invention, by utilizing existing radiator as power source and thermal source, saving the cost increasing power source and thermal source, and saving space.Simultaneously, catalyst of the present invention is by choosing specific components A and B component, this catalyst is made to produce cooperative effect, the organic matter degradations such as the formaldehyde in air, benzene can be called carbon dioxide, and be higher valence state by harmful oxysulfide, nitrogen oxide catalytic oxidation, and then with charcoal absorption, various pollutant is reduced to ppm level.The removal of benzene,toluene,xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde, methacrylaldehyde reaches less than 0.01 milligram/cubic metre, significantly reduces the content of microorganisms in room air simultaneously.
Detailed description of the invention
The present invention is described breathing mask of the present invention by following embodiment.
