It is supplementary to explain, to the purification mode of the extrinsic cycle, adopt the ventilation of indoor and outdoor to reduce the effective measure of the indoor air pollution, through introducing the new trend to the room, and discharge the indoor air to the outdoor, can put and trade the indoor air in the short time, take away the indoor microorganism, thus reduce the density of the indoor microorganism, it is an effective air purification method, can also regulate indoor temperature, humidity, increase the oxygen content, stimulate the blood circulation of the patient, promote sweat evaporation and heat to scatter, thus increase the comfort level of the patient, strengthen the disease-resistant ability of the patient, reduce the probability of nosocomial infection, therefore, the purification mode of the extrinsic cycle is an air purification method easy to operate, economic and effective, safe and environment-friendly.
However, when the method is used for indoor air purification, factors such as outdoor climate conditions, indoor and outdoor temperature differences, patient conditions and the like need to be considered, and when an external circulation purification mode is not suitable, an internal circulation purification mode is needed to realize air purification, so that the external circulation purification mode and the internal circulation purification mode are combined, the good effect of air sterilization and purification in the hospital room can be realized, when the ventilation condition is good, the external circulation purification mode is selected for air purification, and when the indoor and outdoor temperature differences (such as summer and winter) or unsmooth ventilation exist, the internal circulation purification mode is adopted to improve the air quality in the hospital room.
The combined disinfection and purification device 3 comprises a disinfection box 301 and two primary filter screens 302, wherein the primary filter screens 302 are respectively arranged in an indoor air inlet 201 and an outdoor air inlet pipe 203, and play a role of primary filtration for air entering into the purification box body 1, thereby avoiding that large-particle dust in the air blocks a ventilation pipeline (a first air pipe 501, a second air pipe 502, a third air pipe 503, a fourth air pipe 504, a fifth air pipe 505 and a sixth air pipe 506) or a fan (a first air inlet fan 7, a first air exhaust fan 9, a second air inlet fan 10 and a second air exhaust fan 8) in the purification box body 1, an ultraviolet lamp set 11 and a negative ion generating device 12 are arranged in the disinfection box 301, and the air purification device integrates ultraviolet irradiation and negative ion technologies, can achieve the purposes of good dust removal, odor removal, sterilization and disinfection and air purification, and has strong air purification capacity, The lasting stable advantage of effect, anion generating device 12 sets up the below at ultraviolet banks 11, ultraviolet banks 11 is including installation fluorescent tube 31 and a plurality of ultraviolet germicidal lamp 13, installation fluorescent tube 31 sets up in disinfect box 301 inner chamber upper end, ultraviolet germicidal lamp 13 evenly sets up in installation fluorescent tube 31, through setting up ultraviolet germicidal lamp 13 in disinfect box 301, realizes the sterile efficiency of air sterilization, can effectively avoid ultraviolet irradiation to bring bigger sick pain for patient and suffer.
Through the arrangement of the anion generating device 12, a large amount of anions can be generated, the anions are commonly called vitamins in the air, the content of the anions in the air is the key of the quality of the air, and the anions are beneficial to improving the lung function and the cardiac muscle function, improving the sleep quality, promoting the metabolism and having the medical care efficacy; moreover, the negative ions can charge the particles in the air, such as smoke, germs, spores, flock, etc., and the particles are absorbed by the discharge integration device in the negative ion generating device 12, so that the air purifying effect is better.
Further, the ultraviolet germicidal lamps 13 are divided into two groups (when being installed, the two groups of ultraviolet germicidal lamps 13 are connected into a row, one group of ultraviolet germicidal lamps 13 is installed first, then the other group of ultraviolet germicidal lamps 13 are installed, the structures of the two groups of ultraviolet germicidal lamps 13 are completely the same, except that the materials used for installing the lamp tubes 31 outside the two groups of ultraviolet germicidal lamps 13 are different, so that the ultraviolet germicidal lamps 13 are divided into two groups, that is, the installing lamp tubes 31 are divided into two sections with different materials), one group of ultraviolet germicidal lamps 13 emits ultraviolet light with the wavelength of 253.7nm, the other group of ultraviolet germicidal lamps 13 emits ultraviolet light with the wavelength of 185nm, the ultraviolet germicidal lamps 13 belong to a low-pressure mercury vapor pressure lamp, the low-pressure mercury lamp is excited by using lower mercury (<10-2Pa) to emit ultraviolet light, and the emission spectral lines mainly include two: one is 253.7nm wavelength; the other is 185nm wavelength, the two are invisible ultraviolet rays, the ultraviolet rays can sterilize at 253.7nm wavelength, the ultraviolet rays can ionize air at 185nm wavelength to generate ozone, the ozone has high-efficiency sterilization effect with strong oxidizing property, the defects that the ultraviolet rays only spread along a straight line and have dead angles in sterilization can be exactly overcome, and good sterilization and disinfection effects are realized on the air.
It should be added that, if the ultraviolet germicidal lamp 13 wants to emit ultraviolet light with two different wavelengths, mainly the material of the installation lamp 31 is different, if the installation lamp 31 is added with a sufficient amount of titanium (Ti) element in the process of smelting quartz glass, the ultraviolet light transmitting through the installation lamp can be cut off below 200nm, but the ultraviolet light transmitting through 253.7nm is not affected basically, in the invention, the installation lamp 31 is divided into two sections by controlling the addition amount of titanium element in the production process of the installation lamp 31, so that the ultraviolet germicidal lamp 13 can emit ultraviolet light with two wavelengths of 185nm and 253.7nm, and the requirement is met.
Further, the outer surface of the installation tube 31 is coated with the nano-TiO 2 layer 24, and the principle of ultraviolet photocatalysis is applied to integrate the nano-material air purification technology into the installation tube 31, so that the combined disinfection and purification device 3 adds a function of purifying the indoor air, and the basic principle is as follows:
the nano-sized TiO2 layer 24 generates free electron-hole pairs under the irradiation of the ultraviolet germicidal lamp 13 to activate oxygen in the air and generate active oxygen and free radicals, and the reaction process is as follows:
TiO2+hv→e-+h+；
O2-e-→O2-；
H2O+h+→OH+H+；
O2-+H+→HO2；
NO2+OH→HNO3；
