The present invention relates to an ultraviolet instant sterilizer. More specifically, the present invention relates to an ultraviolet instant sterilizer which maximizes sterilization efficiency by improving the UV transmittance by passing a liquid through a bundle of fine transparent tubes and irradiating ultraviolet rays.

In recent years, the sterilization method using ultraviolet rays in the sterilization of various kinds of liquids including water, beverages, juices, vegetable juices, green juices, milk, liquor, etc., such as wastewater, sewage, bottled water, and groundwater, has recently emerged. In the case of chlorine disinfection or other sterilization methods, the effect on the environment is great. Especially, in the case of food or blood, the sterilization method using ultraviolet rays is a safe sterilization method because there is a problem of secondary pollution. It can be used as.

Ultraviolet rays are shorter than the wavelength of visible light (400nm) and longer than x-rays (100nm), and UV sterilization lamps with the strongest sterilizing power of 250-280nm are known as bacteria, viruses, molds, etc. It is widely used for sterilization.

Looking at the sterilization dose to sterilize more than 99% by ultraviolet light for various bacteria are as follows.

In the case of weak bacteria such as Escherichia coli and erythropoies, a sterilization dose of 70 to 90 m 3 / cm 2 is required per minute, and in the case of Staphylococcus aureus, Mycobacterium tuberculosis or Bacillus subtilis, a sterilization dose of 150 to 260 m 3 / cm 2 is required. Sterilization doses of 300 to 630 나 / ㎠ are required for strong bacteria, such as brewer's yeast or William's yeast, and about 1400 to 3700 ㎼ / min for very strong bacteria, such as olive or fruit black or mildew fungi. A sterilization dose of 2 cm 2 is required.

Korean Patent Laid-Open Publication No. 10-2004-0052688 (Spiral Irrigation Type UV Disinfection Reactor), Republic of Korea Utility Model Registration No. 331325 (Sterile Purification Device Using Teflon Tube), Republic of Korea Utility Model Registration No. 396115 (Using spiral tube UV sterilizer) and the like describe a device for sterilizing a liquid using ultraviolet rays, and describes a technique for providing a liquid to be sterilized with a spiral tube and having a spiral tube around the ultraviolet lamp.

In the case of a solid material, a liquid having a lot of minerals or severe turbidity, there is a problem in that the ultraviolet ray transmittance is low and the liquid cannot be sufficiently sterilized. For this reason, in the above prior art, a lot of ultraviolet rays are irradiated to a liquid by using a spiral tube.

However, the following problems exist in the conventional ultraviolet sterilizer using a spiral tube.

There is a problem in that the time for the liquid to stay in the spiral tube for sterilization is very long and the sterilization time is long.

In addition, the spiral tube is made of a Teflon (Teflon) tube or quartz tube with high UV transmittance, when the tube is made of such a spiral, the radius of curvature should be a certain value or more, there is a problem that the size of the device increases. . In addition, since the total length of the spirally wound tube is long, there is a problem that takes a lot of manufacturing costs.

In addition, the amount of UV irradiation for sufficient sterilization is different depending on the type of liquid to be sterilized. In the case of the UV sterilizer using a spiral tube, it is difficult to add an additional spiral tube when the sterilization power is insufficient. have.

In addition, the liquid close to the ultraviolet tube is irradiated with a lot of ultraviolet light, the liquid in the center portion of the tube is less ultraviolet light, so there is a problem in the difference in the degree of sterilization occurs. As a result, in the case of a liquid that receives a lot of ultraviolet rays, a problem occurs in that the liquid is denatured due to excessive ultraviolet irradiation, and in the case of a liquid that receives less ultraviolet rays, sufficient sterilization is not guaranteed.

On the other hand, since the spiral tube has a long length, when the liquid contained in the tube is discharged in the case of washing or the like, its loss is large, and there is a problem in that maintenance is difficult when replacing the tube.

In order to solve the above problems, the present invention, by passing the liquid through a bundle of fine transparent tube to irradiate ultraviolet rays to increase the amount of ultraviolet radiation to the liquid to shorten the sterilization time, it is possible to easily connect the devices in parallel or in series The purpose of the present invention is to provide an ultraviolet instant sterilizer which is excellent in expandability of equipment to improve sterilization capacity or sterilization efficiency, to reduce the size of the sterilizer, and to be easy to maintain.

It is also an object of the present invention to provide an ultraviolet instant sterilizer having a cooling device that maintains the characteristics as described above and maintains a constant temperature of the liquid during sterilization.
