Detailed Description
The present application will now be described in further detail with reference to the drawings, it should be noted that the following detailed description is given for illustrative purposes only and is not to be construed as limiting the scope of the present application, as those skilled in the art will be able to make numerous insubstantial modifications and adaptations to the present application based on the above disclosure.
As shown in fig. 1 to 4, in an air purification and disinfection device for a bus stop, a plurality of upright posts 1 are arranged on a general bus stop as support posts for supporting a rain cover 2, the rain cover 2 is covered above the bus stop, and one to three advertisement boxes 3 are arranged between the upright posts 1 of the bus stop under normal conditions; namely, one side of the advertisement box 3 is an advertisement board sealing box 4, and in order to solve the air problem of a platform, the other side of the advertisement box 3 is provided with an air purification and disinfection device 5; wherein, the bottom of the air purification and disinfection device 5 is provided with an air inlet 51, the top is provided with an air outlet 52, firstly, a primary filter screen 7 is movably embedded at the air inlet 51, and the primary filter screen 7 is an electrostatic electret filter screen; namely, a caulking groove can be designed at the air inlet, and then the primary filter screen is transversely embedded in the caulking groove, and the electrostatic electret filter screen adopts HOMO bulk electrostatic electret dust collecting filter material; the filter material is injected with permanent static electricity by using a unique technology during structure forming, and the static electricity of the filter material has excellent catching capacity on small-particle dust except mechanical interception dust on the surface of the filter material; the fiber is electrostatically charged by selecting the chemical fiber to form an electrostatic field, and the dust particles in the air are efficiently removed by the principle of opposite charges attraction; in the open space of the bus station and the serious disaster area of the dust on the roadside, the primary filter screen is used for primarily filtering larger particles such as dust, and then primarily filtered air is disinfected and purified, so that the air purification efficiency can be effectively improved, the service life of the high-efficiency HEPA filter screen 321 can be prolonged, the replacement frequency of the filter screen is reduced, and the use cost is reduced;
secondly, a squirrel cage fan 53 is arranged between the air inlet 51 and the air outlet 52, an HEPA filter screen 54 is arranged above the squirrel cage fan 53, in addition, a plasma reactor 55 and a titanium dioxide catalysis plate 56 are arranged between the HEPA filter screen 54 and the air inlet 51, through holes 561 are uniformly arranged on the titanium dioxide catalysis plate 56, and the through holes are used as air flow channels; the plasma reactor and the titanium dioxide catalytic board are arranged on the HEPA filter screen 54, so that the staphylococcus aureus, escherichia coli, bacillus subtilis, mould, mycoplasma, hepatitis B, influenza and other virus bacteria in the air entering the device are effectively killed by the two devices; meanwhile, the peculiar smell is removed, the formaldehyde, the smog, the TVOC and other organic waste gases are degraded, and then the primarily sterilized and disinfected air is filtered through the high-efficiency HEPA filter screen 54, so that the service life of the HEPA filter screen 54 can be further prolonged, and certain use cost is reduced;
moreover, because the structure of the air purification and disinfection device is limited, the air outlet faces the rain cover, the efficiency of air circulation after air outlet is not high, weak air circulation can be realized only by natural air flow, even if the air purified and disinfected in the device is fresh again, the air can not be effectively circulated to the side of passengers on a platform, therefore, further, a diversion cover 6 is arranged at the air outlet 52, a diversion fan 61 is fixedly arranged in the diversion cover 6, the shaft of the diversion fan 61 is vertical to a HEPA filter screen 54, namely, the vertical upward wind flow can be guided to the horizontal direction by the diversion fan, a diversion groove 62 is arranged on the side surface of the diversion cover 6, and the opening of the diversion groove 62 inclines downwards; the air guided by the guide fan is directly blown to the human body range under the action of the guide groove, so that passengers on the platform can take respiratory fresh air in the first time, and the blown air flows obliquely downwards, and the air inlet enters from the bottom, so that small air circulation can be formed in front of the platform advertisement box, the air near the upper half of the passengers is covered, and the air condition during waiting for vehicles is fully improved;
regarding the working principle of the plasma reactor 55 and the titanium dioxide catalyst plate 56, firstly, the titanium dioxide (TiO2) photocatalytic purification technology is a high-tech leading edge purification technology which has emerged in recent years; the photocatalyst is a photo-semiconductor substance which utilizes a light source to perform catalytic reaction to promote the decomposition of organic matters, and the energy of the light source excites gas molecules around TiO2 to generate free radicals with extremely strong activity under the action of ultraviolet rays of titanium dioxide. The free radicals with extremely strong oxidizing power can almost decompose most organic substances and part of inorganic substances to generate holes with strong oxidizing power, and the energy of the holes is equivalent to the high temperature of 15000K; the free radicals can also damage the cell membrane of the bacteria, so that cytoplasm is lost, and then nucleus is oxidized, so that the bacteria are killed; it can directly kill bacteria and thoroughly decompose organic matters into inorganic harmless micromolecules such as CO2, H2O and the like, thereby achieving the effects of sterilization, deodorization and air purification; however, when the existing titanium dioxide (TiO2) photocatalytic purification technology is used alone, the photocatalyst must be irradiated by ultraviolet rays to act, and the ultraviolet discharge lamp is easy to damage and the ultraviolet rays also have harm to human bodies; in particular, it is not useful for particulate contamination; the surface of the negative electrode of the plasma reactor is made of an aluminum plate which is subjected to oxidation treatment, TiO2 is easily laid on the upper layer, the Al2O3 layer generated by the oxidation treatment is thin, corona discharge is not influenced in an 18KVP-P narrow pulse high-voltage electric field, when the plasma reactor is subjected to the corona discharge, blue light emitted by a reaction area contains ultraviolet rays, the wavelength is 300-400 nm, the light intensity peak value is 357nm, the forbidden bandwidth of TiO2 is 3.2eV, and the corresponding ultraviolet wavelength threshold value is 387.5 nm. Experiments show that when TiO2 is used for air disinfection and purification, the wavelength of the catalytic light source is preferably less than or equal to 387.5nm, and the condition that the peak value of the ultraviolet wavelength emitted by the reaction zone is 357nm is met. Therefore, the ultraviolet light source can be saved, and the defects of damage of the ultraviolet discharge lamp, damage to human bodies and high power consumption of the ultraviolet light source are avoided; finally, the two devices are combined together to generate a disinfection factor, namely, low-temperature plasma and free radicals generated by exciting TiO2 to disinfect and purify.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
