Description
Technical Field
The invention relates to an air disinfection and purification system and a space disinfection machine, and belongs to the technical field of air purification.
Background
With the development of modern industry, haze weather continuously increases, the PM2.5 value of many cities frequently explodes the table, and the air quality is often in moderate or severe pollution. Although governments are constantly increasing the efforts to treat air pollution, experts show that this treatment is not significantly improved for a short period of time due to the complex causes of haze. In order to breathe clean air, more and more people in China begin to shop for air purifiers. In market and supermarket purchasable brand indoor air purifiers, the multilayer filter screen and activated carbon adsorption are the most widely applied technologies, and represent companies such as philips, honowell, american, grand and Panasonic. Among them, the HEPA (high efficiency particulate air filter) in the multi-layer filter screen plays the most important role, the effective rate of HEPA to 0.1 micron and 0.3 micron reaches 99.7%, and the removal efficiency to the particle with the diameter of more than 0.3 micron reaches more than 99.99%, so that the HEPA is the most effective filtering medium for pollutants such as smoke, dust, bacteria and the like. The activated carbon filter screen utilizes the high-efficiency adsorption performance of activated carbon on benzene, toluene, xylene, formic acid, oxygen, sulfur dioxide and the like to purify the air passing through the filter screen. However, in the market, air purifiers with various functions and brands are numerous, and the mainstream air purifier in the market at present has a European product: the purifier mainly adopts filtration as a main material, generally only three layers of coarse filtration screens, an active carbon layer and HEPA filtration are adopted, and some of the three materials are different in possible calling, and the purifier is collectively called as an adsorption purifier, is only effective on conventional gas systems such as smoke, dust and PM2.5, and can effectively remove dust, harmful gas and bacterial microorganisms by combining HEPA and active carbon components in daily life, so that the requirement of clean air is met. However, in the long term, the efficient filter screen and the activated carbon both act in a manner of trapping pollutants on the material, theoretically, the pollutants have respective adsorption capacities, and desorption is easy to occur after saturated adsorption is achieved. Therefore, the greatest disadvantage of these two technologies is that the purifying effect is reduced with time, and the indoor air purifier is likely to operate continuously for 24 hours a day, which results in frequent replacement of the filter net by the user, and the replaced filter net will cause secondary pollution if not disposed properly. But has no way to chemical pollution such as formaldehyde, benzene series, TVOC, ammonia gas and the like generated by decoration pollution, and is especially inexperienced to respiratory virus infection caused by seasonal influenza, avian influenza H1N1 SARS virus, new coronary pneumonia and various viruses.

fig. 2 is a schematic diagram of the air treatment technology of the present invention.
Detailed Description
The invention is further described with reference to the following figures and examples.
As shown in figure 1, the space sterilizer comprises a shell 1, a primary filter screen 2, a plasma high-voltage electric field device 3, an anatase catalyst net 4, an ultraviolet lamp 5, a copper-silver nano composite catalyst net 6, an active carbon net 7, a HEPA air filter 8 and a negative oxygen ion releaser 10. The shell 1 is provided with air inlet and is the position of primary filter screen 2 in figure 1 to and air outlet 12, and inside the shell 1, between air inlet and air outlet 12, set gradually primary filter screen 2, plasma high-voltage electric field ware 3, sharp titanium catalyst net 4, ultraviolet lamp 5, copper silver nanometer composite catalyst net 6, activated carbon net 7 and HEPA air cleaner 8. A negative oxygen ion releaser 10 is also arranged in the shell 1. The air quality sensor 11, the fan and the microprocessor (not shown in the figure) are arranged in the shell, and the air quality sensor 11 can detect the temperature and humidity of air, the TVOC concentration, the dust concentration, the equivalent CO2 concentration and the equivalent formaldehyde concentration. The fan adopts a multi-wing centrifugal wind wheel direct current brushless variable frequency motor. The air quality sensor adopts a seven-in-one sensor, and can detect temperature, humidity, formaldehyde, TVOC, CO2, PM2.5 and PM 10. The value detected by the air quality sensor is transmitted to the microprocessor, and the value is displayed on the capacitive touch display screen 13.
The air disinfection purifier has two modes of manual operation and automatic operation, and can be selected by users. In the automatic mode, when any one of the numerical values is larger than a preset threshold value, the microprocessor unit controls the fan to be electrified to work; when any value of the TVOC concentration and the formaldehyde concentration exceeds a set threshold, the microprocessor unit controls the plasma high-voltage electric field device and the ultraviolet light source to be electrified and work.
The working principle is as follows:
as shown in fig. 2, when the machine is started, the fan 9 starts to work first, which can stir air well to make indoor air flow circularly, after the polluted air in the room enters the primary filter screen 2, some physical particle impurities are filtered and intercepted, and the plasma high-voltage electric field generated by the air plasma high-voltage electric field device 3 after primary filtering, high-energy electrons collide with various pollutant molecules in the air to generate a series of elementary materialization reactions, and generate a plurality of active free radicals and ecological oxygen in the reaction process to destroy nucleic acids and proteins in various viruses and bacteria effectively, so that the normal metabolism and biosynthesis cannot be carried out, and the death can be caused. And ions and objects in the plasma are condensed to effectively collect fine particles of which the particle size is as small as submicron, so that the physical particle burden of a subsequent unit is reduced and protected. The polluted air is effectively purified after passing through a plasma electric field, residual formaldehyde, benzene series and other chemical pollutants after primary purification are catalyzed and decomposed by the anatase catalyst net 4 under the irradiation of the ultraviolet lamp 5, and residual bacteria and viruses are further oxidized and removed. After the purified air after photocatalytic decomposition is uniformly subjected to bacteriostasis and sterilization through the copper-silver nano composite catalyst net 6, the front-section electric field, the bacteria bodies subjected to catalytic sterilization and the nano microparticles are adsorbed by the activated carbon net 7, meanwhile, trace organic matters adsorbed by the activated carbon are resolved and regenerated by hydroxyl oxidation free radicals generated by a front process, trace ozone is reduced by carbon, and the service life of the activated carbon is greatly prolonged, and even the activated carbon does not need to be replaced. The air is absorbed by the active carbon and then is efficiently filtered by the HEPA air filter 8 and then is discharged cleanly. 3 hundred million negative oxygen ion releasers 10 are additionally arranged at an air outlet 12 to form a negative ion flow, so that the space gas is further cleaned and purified. To further enhance the primary filtration effect, a washable coarse filter screen 14 may be added before the primary filter screen 2.
