Abstract
The utility model relates to an ultraviolet sterilization apparatus, which mainly comprises a cylinder body, an ultraviolet lamp strip, and a lifting rack. An air inlet is provided on one end, an air outlet is provided on the other end, two groups of ultraviolet lamp strips in parallel are provided in the cylinder body, an air blower is disposed between the two groups of ultraviolet lamp strips or on the air inlet or the air outlet, and a lifting rack is mounted under the cylinder body in order to facilitate the height adjustment. Because the air blower periodically drives the indoor air through the cylinder having an ultraviolet sterilization lamp and an ultraviolet ozone decomposition lamp, namely harmful bacteria and infectious virus in the indoor air can be sterilized rapidly. At the same time, because the ultraviolet lamp is provided in the cylinder that people could not see, and ultraviolet lamp at the air outlet of the cylinder can decompose the ozone generated by the ultraviolet sterilization lamp at the front portion, so that the discharging standard permitted by the nation can be achieved.
Description
Technical field
This utility model belongs to indoor sterilizing technical field, specifically a kind of UV sterilizer of utilizing ultraviolet radiation to kill various pathogenic bacterias.
Background technology
Common sterilization (sterilization) method mainly contains physics and chemicals sterilization.Physical sterilization is simple and comparatively effective sterilization.Concrete have Mechanical Method and a heat-sterilization, and the most effective in heat-sterilization then is the sterilization of light.We know that big sunlight sterilization mainly is an action of ultraviolet ray, and after microorganism was subjected to solar radiation, protoplasm generation photochemical effect caused the distortion of pathogen protein coagulating and death.Be exposed to the sun under direct sunlight attached to the pathogen of article surfaces such as clothes, bedding and can kill in 3---6 hour.As typhoid fever, paratyphoid fever, bacillary dysentery etc. pathogen 2---3 hour, when paracholera vibrios is dry 30 minutes, pathogen such as influenza, pertussis, epidemic encephalitis, measles, chickenpox were killed under direct sunlight very soon.
And the artificial ultraviolet that utilizes mercury quartz lamp or hydrargyrum Burdick lamp to be obtained is usually used in the air sterillization in laboratory, operating room and the food enterprise workshop, generally uses 15 watts (every square centimeter 30 milliwatts approximately), and irradiation time must not be less than 30 minutes.But artificial ultraviolet radiation also can have side effects to human body, and ultraviolet radiation people physical ability produces erythema, and ultraviolet radiation also can cause electric ophthalmia; Can produce ozone less than the airborne oxygen of the irradiation under ultraviolet ray of 185mm, also can be harmful after surpassing finite concentration.
Therefore, when carrying out air sterillization with traditional irradiation under ultraviolet ray mode, the people must withdraw from a room, and at present, can't use irradiation under ultraviolet ray to give air sterillization in the indoor and public place that the people is arranged.
Summary of the invention
The purpose of this utility model provides a kind of irradiation under ultraviolet ray flow air of utilizing, and utilizes the indoor UV sterilizer of ultraviolet light ozone decomposition simultaneously.
Feature of the present utility model is that an end is provided with in the simple shape body that air inlet, the other end be provided with air outlet and is provided with at least two group quartz burners arranged side by side, between any therein two groups of quartz burners or air inlet end or air opening end be provided with a blower fan, and divide into a crane in cylindrical body.Every group of above-mentioned quartz burner can be a quartz burner, also can two, three or four or more the corresponding combination type quartz burners that are provided with.
The size of size, circulation of air situation and movement of population amount according to the sterilization place, determine the contact area of quartz burner and air, select concrete shape, quartz burner may be selected to be tapering type screw-like fluorescent tube, annular lamp tube, square fluorescent tube, triangle fluorescent tube, straight pipe type fluorescent tube or special-shaped fluorescent tube.
For the ease of the dust of maintenance and removal Burdick lamp tube-surface, and change quartz burner, then cylindrical body is provided with one and opens lid.This unlatching lid can be one or two tegillum, also can be the unlatching lid that runs through whole cylindrical shell.Middle part in cylindrical body also is set with one handle.
In order to make this utility model be suitable for using various environment, if the bottom of above-mentioned cylindrical body is provided with one liter of valency frame, one-tenth is for ease of the mesa structure in room air sterilization, so that to the surface of various clothing, general merchandise, article of everyday use and food in market or the shop, comprise that " dead angle " carry out room air sterilization.
More obvious for the bactericidal effect that makes quartz burner, be tapering type screw-like quartz burner then at quartz burner near the air air inlet, make contact area and the time that fully increases quartz burner and air.
The sterilization principle: ultraviolet has sterilization functions, after antibacterial is subjected to ultraviolet radiation, because protein molecular is subjected to photochemical action destruction and death in the body.
The reactive group reason that ozone decomposes, because the many gaseous materials with reproducibility of ozone energy oxidation, so the ozone concentration in upper atmosphere can being reduced property species (as: CO, NO, SO
2, halogen atom etc.) reduce with the reaction of ozone.At wavelength is under the irradiation under ultraviolet ray of 220-320nm, the ozone oxygen-derived free radicals that can dissociate out:
O
3+hv(220-320nm)——→+O
2+O
-
This utility model is owing to utilize blower fan (exhaust blower or air-introduced machine) indoor air periodically to be reached from having " ultraviolet germicidal lamp " in the cylindrical shell of " ultraviolet and ozone decomposition lamp " to pass through, can with the harmful pathogenic bacteria in the room air and virus spread (as, enteric infection virus, the respiratory infectious disease poison, the arthropod borne infection poison) kills fast, simultaneously, because Burdick lamp is arranged in the cylindrical shell that people can't see, and also the ozone that anterior ultraviolet germicidal lamp produced can be decomposed at the air air opening end Burdick lamp of cylindrical shell, reach the discharge standard that country allows.This utility model owing to all be not provided with at inlet and outlet does not block, make flow air do not exist the ultraviolet sterilization light irradiation less than " dead angle ", so sterilization and disinfection is effective.And adopt the inlet and outlet place various filtrations to be set, to purify thin film and to utilize the alkali metal hydroxide drainage screen to come the ozone of decomposing excessive, and all can produce the ultraviolet sterilization light irradiation less than " dead angle ", filter Netease to wear out, and the cost costliness.
This utility model has also that cost is low, high, range of application wide (can be widely applicable for the air sterillization in the places such as hospital, mobile vehicle, school, office, public place, various market for money, laboratory, operating room and food enterprise workshop) are imitated in sterilization, to human body have no side effect, characteristics such as simple and reasonable, long service life.
