Types of ultraviolet sterilization lamps (mercury lamps) and their application in disinfection

1. Generate various low-voltage mercury lamps in sterilization

The outer casing of the low-pressure mercury vapor discharge ultraviolet sterilized lamp is made of quartz glass tube or transmissive wave ultraviolet glass tube, and the internal pressure inert gas and a small amount of hustle are filled with metal cold electrodes or hot light wire electrodes, by adding high pressure or triggering the two poles. After the high pressure is started, the discharge is maintained by a lower supply voltage, resulting in ultraviolet rays based on 253.7 nm. The ultraviolet sterilization is very strong, and it can destroy bacteria or viruses that are harmful to the human body, resulting in disinfection. The main varieties of low pressure mercury vapor discharge ultraviolet disinfection lamps are as follows:

1.1 hot cathode low pressure mercury bactericidal ultraviolet lamp

The electrode of such a discharge lamp is wound into a double helical wire with tungsten wire, coated with barium carbonate, bartened calcium carbonate mixture, and when heated is heated, the mixture is activated to form calcium, strontium, barium oxide. When the lamp is started, the filament is heated to transmit electrons, bombard the mercury vapor in the lamp tube, so that the outer electron transition of the mercury atom to the high-energy rail position becomes excited. The electrons on the transition to the high-energy track can only stay 10-5 ~ 10-11s, and then fall back to the low-level track while releasing energy in the form of ultraviolet rays. This light radiation is ultraviolet, 95% or more wavelengths of 253.7 nm, and there is a small amount of wavelength of 184.9 nm, 404 nm, 435 nm, 545 nm, 577 nm, 579 nm.

The pressure of mercury vapor is about 0.006 torr at low pressure mercury lamp discharge, generally using quartz glass having an ultraviolet transmittance greater than 80%. This lamp is the highest in the temperature of 40 ° C.

The low-voltage mercury lamps also include the following four.

1.1.1 straight tube ultraviolet sterilization lamp

The straight tube ultraviolet sterilization lamp is the most classic structure, the length of the lamp and the diameter available formula. The straight tube-type ultraviolet sterilization lamp prepared by quartz glass tube, and the radiation intensity of 30W lamps is above 90 μW / cm 2 (1 m), requiring no less than 70 μW / cm2 in use. The lamp has a life of 3000 hours, with a number of powers of 40W, 30W, 20W, 15W, 10W, 8W, 6W, 4W.

1.1.2 H-type hot cathode low pressure mercury ultraviolet sterilization lamp(254nm 185nm 10000h UV lamp for water purifier disinfection)

9W H-type thermal cathode low pressure mercury ultraviolet sterilization lamp, the radiation intensity at a distance of 3 cm from the lamp is greater than or equal to 200 μW / cm2 at 100 cm from the lamp 100 cm.

1.1.3 Low O3 Ultraviolet Light

Whether it is a straight tube or an H-lamp, it can be made to the low O3 ultraviolet lamp, and 0.01% to 0.05% titanium oxide and 0.07% alumina are added to the quartz glass, so that ultraviolet rays having a wavelength of less than 200 nm are absorbed, resulting O3 is very small.

1.1.4 High O3 UV lamp

This lamp produces a large amount of 253.7 nm ultraviolet rays, which also radiates strong 184.9 nm ultraviolet rays, resulting in a large number of O3, which has improved disinfection effect due to the synergistic effect of O3 and UV.

1.2 cold cathode low pressure mercury ultraviolet sterilization lamp

The lamp is made of nickel, which is filled with mercury and argon inside the quartz tube, and the cold cathode is emitted by the strong electric field, and the mercury is emitted, bombarding the mercury atom, so that it excites luminous. The lamp can be made into a variety of shapes, such as disc amphony, U-shaped, straight tube shape, etc., radiated ultraviolet rays have a wavelength of 253.7 nm.

1.3 high pressure mercury ultraviolet sterilization lamp

The pressure of mercury vapor in the lamp tube can reach several atmospheric pressure, the power can reach 500 ~ 1000W or higher, only a small portion of the radiation spectrum is sterilizing ultraviolet, but the total energy is large, so it is still a good disinfection UV light source Generally, it is generally used for disinfection of water.

Ordinary glass and plexiglass do not pass through 253.7 nm ultraviolet rays, but quartz glass can pass through more than 80%, and the general plastic transmits is also very low. The polyvluoroethylene resin film (0.1 mm thick) can be about 40% by 253.7 nm ultraviolet rays, and the ethylene copolyester film (0. 1 mm thick) can pass through 40%. 253.7M Ultraviolet wire can be penetrated by 2 cm, while the air clock is blocked when the air clock is transmitted.

253. 7 nm Ultraviolet is irradiated with the surface of the material - it will be absorbed, converted into the internal energy of the substance, and it is not easy to penetrate into the deep part of the item, so the ultraviolet irradiation can only kill the surface of the item.

253.7 nm ultraviolet rays incurred to the two media interfaces produced reflecting, and refraction occurs when entering the second medium. Various materials have different reflection coefficients of 253.7 nm ultraviolet rays, magnesium oxide is 80% to 93%; polished aluminum is 60% ~ 90%; white is 46%; white lime is 40%, and the white tile is 4.7%. The reflective material of the ultraviolet luminaire can be selected based there.

2. UV disinfection lamp to the killing of microorganisms

The strongest band of bactericidal effect is about 254 nm. UV can kill a variety of microorganisms, including bacteria, fungi, viruses, and ricks. Each microorganism has its specific ultraviolet dead dose threshold. The bactericidal dose k is the product of irradiation intensity and irradiation time. Use the following formula: k = IT

When the strength of the ultraviolet source is higher than 40 μW / cm 2, the high intensity is short-term or low-intensity long-term irradiation, which can obtain the same effect. Ultraviolet Line to the fatal dose (μW-S / CM2) of the surface of the object: Golden Staphylococcus, 2 180 ~ 4 950; White Staphylococcus, 3300 ~ 4 200; Escherichia coli, 2 100 ~ 6 400; Pseudobacter, 6 500; UV line to microorganism kill dose, available mathematical model estimation (in the formula Y = kill rate, x = dose):

Wax spots:

lg (100-y) = 10.7142-2 .4078 lgX;

Bacillobacterium sputum germination:

lg (100-y) = 9.101 3-2.05431 lgX;

E. coli:

lg (100-y) = 7.4113-2. 1692 lgX;

White Staphylococcus:

lg (100-y) = 10.366 2-2.7391 lgX.

Microorganisms in the water, killing the dose of 99. 9%: Bacillus spore, 40 000; E. coli and golden Staphylococcus, 12 000; tuberculosis, 20 000; influenza virus, greater than 5000.

In general, Landacids are most sensitive to ultraviolet rays, followed by Gram-positive cocci; bacterial spore resistance; viruses will also be killed by ultraviolet, their resistance is mediated by bacterial propaguts and spur between.

The ultraviolet high anti-bacteria nuclifinals, radiation resistant microbluts and orange-yellowed sputum; there is a microbacterial, sterilic bacteria, mice, yeast, and protothenesis; low anti-anti-vane virus, E. coli , Golden Staphylococcus aureus, ordinary deformation bacillus, army colony, Brusul yeast and T3 E. coli phage. Bacillus Black Variety ATCC 9372 strain has been used as ultraviolet disinfection indicators.

3. Factors affecting ultraviolet disinfection

3.1 Effect of voltage

The radiation intensity of the ultraviolet source is significantly affected by the voltage, the same ultraviolet light source, when the voltage is insufficient, the radiation intensity is much reduced. 30W straight tube quartz ultraviolet lights different voltage radiation intensity,

Available in the formula:

Y = 1.287x-177.87

In the formula, Y-the theoretical value of UV strength, unit μW / cm2;

X-voltage, unit: V.

If the strength is 100 μW / cm2 at 220V, the control line of the new ultraviolet lamp radiation intensity is measured at different voltages is below

Y = 1.287x-183.14

If the intensity is 70 μW / cm2 at 220V, the radiation intensity control line measured under different voltages is

Y = 1. 287x-213.14

3.2 Distance effect

In general, the radiation intensity of the ultraviolet lamp is inversely proportional to the distance of the distance. The radiation intensity of the 30W low-pressure mercury thermal cathode straight tube decreases from the increase of the tube distance x, and the two are indexed.

Its index curve equation is

Y = 102.885* 9-0.760* 8x

According to this formula, the radiation intensity of the ultraviolet lamp at different distances can be calculated.

3.3 Influence of temperature

The effect of temperature on ultraviolet disinfection is achieved by affecting the radiation intensity of the ultraviolet light source. In general, the ultraviolet light sources are the strongest in sterilization of radiating in 40° C. The temperature decreases, the output of the ultraviolet lamp is reduced; the temperature is higher than 42 ° C, and the ultraviolet absorption of radiation is increased, and the output is also reduced. Therefore, too high and too low temperatures are unfavorable to ultraviolet disinfection. However, some bactericidal tests have proven that the temperature on the bactericidal effect of ultraviolet rays is small in the range of 5 to 37 ° C. The microorganism becomes more sensitive to ultraviolet rays at low temperatures.

3.4 Effect of relative humidity

When disinfecting air, the relative humidity has an effect on disinfection effects. When RH is too high, the water in the air increases, and the ultraviolet rays can be blocked, so the relative humidity is preferably 60% or less when using ultraviolet sterilization. When disinfecting surface, if the light source is relatively far from the light source, the moisture particles in the air also affect the disinfection effect.

3.5 Impact of irradiation time

The disinfection effect of ultraviolet rays is indexed with an exponential relationship with the expiration dose.

N / no = e-kit

In the formula, N0 - illuminates the number of primary bacteria;

N - irradiates the number of bacteria after a certain period of time;

T - illumination time;

I - illumination intensity;

K - constant.

It can be seen from the above formula to increase the irradiation time t, or increase the irradiation intensity, and can increase the disinfection effect, which is the product of the irradiation intensity | and the irradiation time, so that the killing rate reaches a certain degree, it must be guaranteed enough Illumination dose. When the radiation intensity of the ultraviolet source is required (greater than 40 μW / cm2), the required irradiation dose can be achieved by adjusting the irradiation time.

3.6 Influence of the protection of organic matter

When the microorganism is protected by organic matter, it is necessary to increase the amount of irradiation, as the organic can affect the penetration of the ultraviolet line to the inside of the microorganism, and groups to absorb ultraviolet rays.

3.7 Influence of microbial species and quantity

Different microorganisms are different from the level of the ultraviolet rays, and it is necessary to determine the amount of irradiation dose based on the type of microorganism. Detained items. The more the amount of microorganism contaminated, the worse the disinfection effect, so the type and quantity of contaminated microorganisms on the disinfection target before disinfection is therefore necessary to determine the irradiation dose.

4. Application of ultraviolet disinfection lamp in disinfection

4.1 Scope of UV disinfection lamp

Ultraviolet sterilization lamps can kill the measles virus, tuberculosis, influenza, adenovirus, spinal spinal virus virus, Collic virus, Staphylococcus, meningitis, Pneumococcus, and other microorganisms. Ultra-ultraviolet disinfection air is a simple, convenient, cheap, and effective way.

Ultraviolet wire can also be used for disinfection of the surface of the object. At the same time, it also has a good bactericidal effect on the microorganisms in the water, no residual damage, and does not form a harmful product after disinfection, so it can be used as a drinking water disinfection. Ultraviolet rays have good kills on microorganisms in sewage, which can be used for sewage disinfection.

Since the ultraviolet sterilization lamp has the function of air disinfection, surface disinfection and water disinfection, it can be widely applied to public places and public products, cultural entertainment, bathrobes, hotels, restaurants, bars, tea venues, public And taxi boxes, light rails and subway compartments, aircraft and ship cabins, shops and shopping venues, community event places, schools, libraries and bookstores, common secondary water supply tanks and water storage containers, swimming pools, banks and currencies, hobbies, Sports venues and public fitness equipment, beauty salon, air conditioning systems, etc., prevent pathogens from being propagated in public places or through public products.

4.2 Various applications and precautions for ultraviolet disinfection lamps

4.2.1 Disinfection on the surface of the item

When disinfecting the article surface with irradiation, it is preferable to use a portable ultraviolet sterilizer to move in close distance, or an ultraviolet lamp hanging irradiation can also be taken. For small items, it can be illuminated in the ultraviolet sterilized box. Due to different types of microorganisms, the irradiation dose must be used to reach the target microorganism when disinfected with ultraviolet sterilization. When killing general bacterial breeding, the irradiation dose should reach 10,000 μW*S / cm2; kill bacterial splits should reach 100,000 μW*S / cm2; viruses on the resistance of ultraviolet rays and between bacterial propaguts and sparse; fungi The resistance of spores is stronger than bacterial spur, sometimes irradiating to 600,000 μW*s / cm2; when disinfecting target microorganisms are unknown, the amount of irradiation should not be less than 100000μW*S/ cm2. The irradiation dose is the product of the irradiation intensity and irradiation time of the ultraviolet lamp used to irradiate the object. Therefore, according to the irradiation intensity of the ultraviolet light source, the time required to be irradiated can be calculated.

4.2.2 Disinfection of indoor air

When disinfecting indoor air with an indirect illumination method, the preferred high-intensity ultraviolet air sterilizer, not only the disinfection effect is reliable, but can be used when there is any activity in the room, which is generally fired for 30min to achieve disinfection. Under indoor unmanned conditions, the indoor air is directly disinfected, and ultraviolet lamp hanging or moving direct irradiation can be taken. When indoor suspended ultraviolet sterilization, the number of ultraviolet sterilized lamps (30W ultraviolet lamps at 1.0 m) should be mounted, and the average is not less than 1.5W, and the irradiation time is not less than 30 min.

4.2.3 Disinfection of water and other liquids

Division of water and other liquids can be irradiated with water or irradiation. Ultraviolet light sources should be installed with quartz glass protection hoods when using water irradiation. Regardless of the method, the aqueous layer thickness should be less than 2 cm, and the water flow rate should be determined according to the strength of the ultraviolet source. Signaling water must reach the health standards specified in the state.

4.3 Precautions when using ultraviolet disinfection lamps

The first is during use, the purity of the ultraviolet lamp(254nm 185nm 10000h UV lamp for water purifier disinfection) should be kept, generally wiped once every two weeks, and it is found that the surface of the lamp is dust and oil, and should be wiped at any time. Secondly, when the ultraviolet lamp is dispensed indoor air, the room should be kept clean, reducing dust and water mist, the temperature is less than 20 ° C or higher than 40 ° C, and the relative humidity is greater than 60%, the irradiation time should be appropriately extended. When the surface of the ultraviolet disinfecting article, the illumination surface should be irradiated with the ultraviolet rays and should be sufficiently irradiated. Finally, it must be noted that the ultraviolet light irradiated by the lamp is not allowed to illuminate the human eye or exposed skin, so as not to avoid the buddy.
