Definitions
- the present invention relates to an ultraviolet irradiation apparatus, and more particularly, to an ultraviolet irradiation apparatus that performs a sterilization process by irradiating a fluid with ultraviolet rays by collectively arranging a plurality of general-purpose straight-tube ultraviolet lamps without electrodes.
- ultraviolet irradiation devices have been used for, for example, sterilization, disinfection and decolorization of water and sewage, deodorization and decolorization of industrial water, bleaching of pulp, sterilization of medical equipment, and the like.
- Techniques for performing processes such as sterilization by irradiation are well known.
- this ultraviolet irradiation apparatus as shown in FIGS. 5 and 6, a plurality of straight tube lamps 14a are housed in protective tubes 14b, respectively, and the liquid 1 to be treated flows outside the protective tubes to irradiate ultraviolet rays. Going.
- a straight tube lamp is a discharge lamp that has a rod shape and has filament electrodes at both ends of the lamp that cause discharge in the glass tube.
- the lamp that is converted and used for lighting is the so-called straight tube fluorescent light
- Ultraviolet lamps are lamps in which the glass tube is made of ultraviolet-transmitting quartz glass or the like and the inner surface of the glass tube is not coated with a fluorescent paint.
- straight-tube ultraviolet lamps for sterilization that are generally commercially available are low-pressure lamps having a low gas pressure inside the lamp, and the capacity of one lamp is generally as small as 100 W or less. This is because when large power is input to the lamp, the temperature inside the lamp rises, the output near the wavelength of 254 nm that determines the sterilization performance decreases, and the sterilization efficiency decreases.
- low-pressure UV lamps have a limit to the power that can be injected per lamp, and the sterilization capacity per lamp is low.
- many small-volume lamps constitute an ultraviolet disinfection system.
- the number of protective tubes 14b used for the lamp body that seals and stores the lamp also increases, which complicates the structure of the UV disinfection device and degrades cost performance.
- the present invention reduces the number of wirings and parts between the lamp and the power supply unit in the conventional ultraviolet disinfection apparatus using the straight tube type ultraviolet lamp, prolongs the lamp life and reduces the labor required for lamp replacement.
- Another object of the present invention is to provide an efficient, inexpensive, large-capacity ultraviolet irradiation apparatus by controlling the temperature of an ultraviolet lamp to an optimum value.
- the present invention of claim 1 comprises a plurality of internal electrodes disposed at a central portion and a general-purpose ultraviolet lamp which emits ultraviolet rays at the time of discharge so as to surround the lower electrode.
- a plurality of straight tube type UV lamps are collectively subjected to electrodeless discharge by an ultraviolet irradiation device having an external electrode provided and a flow path formed so that a liquid to be processed flows along the outer periphery of the lamp body.
- the external electrode is an outer wall of the flow path.
- the liquid to be treated is an external electrode.
- the straight tube ultraviolet lamp is partially protruded to the outside of the lamp body, so that the straight tube ultraviolet lamp is directly in contact with the liquid to be treated and the straight tube ultraviolet lamp is protruded.
- the lamp temperature is optimized by adjusting the contact area between the liquid to be treated and the straight-tube ultraviolet lamp by controlling the amount of heat transfer from the lamp to the liquid to be treated.
- an electrodeless ultraviolet disinfection apparatus can be configured at a low cost by using a general-purpose straight-tube ultraviolet lamp, and the filament electrode inside the straight-tube ultraviolet lamp is not used. Therefore, there is no need to provide electric wiring to each electrode of the lamp, and at the same time, since there is no electric wiring, the straight tube type ultraviolet lamp can be easily brought into direct contact with the liquid to be treated. As a result, the straight tube UV lamp can be cooled directly with the liquid to be treated, and the temperature of the straight tube UV lamp can be optimally controlled by adjusting the contact area between the straight tube UV lamp and the liquid to be treated, thereby improving the UV conversion efficiency. (254 nm wavelength output Z lamp input Power) can be improved.

- Fig. 2 is a cross-sectional view taken along the line A-A shown in Fig. 1.
- FIG. 3 is a diagram showing a BB line shown in FIG.
- Fig. 4 is a detailed view of part C shown in Fig. 1.
