と流れ、紫外線による殺菌処理を受B1 Objective of the Invention (Field of Industrial Application) This invention relates to a method for sterilizing fluid, particularly cooling water in a cooling water pipe on the secondary side of a lower water tank of a cooling tower, using an ultraviolet sterilizing lamp. Device. (Prior Art) Conventional sterilizing lamps are inserted into the fluid through the elbow of the piping, or the piping is provided with a bypass pipe, and this bypass is set to be of a flowing type. (Problem M to be solved by the invention) In the known device as described above, only a small portion of the water flow flows near the germicidal lamp and comes into contact with it, and the fluid flows at high speed, so the time for exposure to ultraviolet rays is short. It becomes too short and sufficient sterilizing effect cannot be obtained. In addition, when installing the germicidal lamp in the elbow, a long tube must be installed in one arm of the elbow in order to accommodate the germicidal lamp, and since the diameter of the tube is small, it is difficult to install the germicidal lamp.
There is a risk of contact with the inner surface of the tube during removal and damage. Therefore, not only the device becomes complicated, but also the operation of replacing the germicidal lamp is quite troublesome. 8. Structure of the invention (means for solving the problem) In order to achieve the above-mentioned problem, the fluid sterilization method of the specific invention according to this application forms a fluid deceleration part with a large cross-sectional area in a part of the piping. The present invention is characterized in that the fluid is decelerated in the fluid deceleration section and then sterilized using an ultraviolet germicidal lamp. A fluid sterilization device that is a related invention that implements this patented invention has a fluid deceleration section with a large cross-sectional area formed in a part of the piping, and a plurality of ultraviolet sterilization lamps are detachably arranged in this fluid deceleration section. It is characterized by The piping is a straight pipe with a circular cross section, and the fluid reduction section is
An invention characterized in that it consists of a rectangular parallelepiped pipe connecting straight pipes on the downstream side and the upstream side is advantageous in terms of its structure. The piping is a straight pipe with a circular cross section, and the fluid reduction section is
The invention, which is characterized by being composed of a rectangular parallelepiped-shaped cylindrical body connecting straight pipes on the downstream side and the upstream side, is advantageous in terms of sterilization because no stagnation occurs in the flow of fluid. It is desirable that the plurality of ultraviolet germicidal lamps detachably disposed within the fluid deceleration section be disposed parallel to each other with gaps in between, in a posture transverse to the flow direction of the fluid flowing through the piping. The ultraviolet germicidal lamps may be arranged parallel to each other with a gap in between, in an attitude parallel to the flow direction of the fluid flowing through the piping. The straight pipe may be configured as a horizontal horizontal pipe extending from the lower water tank of the cooling tower to the load section. The ultraviolet sterilizing lamps are arranged in parallel with each other so that the ultraviolet sterilizing lamps are vertically or horizontally oriented across the flow direction of the fluid flowing horizontally in the horizontal drawing pipe. For air removal, it is preferable that the fluid deceleration section is provided with a peacock for air removal at the upper part thereof. If the piping is an air conditioning duct, it is effective in sterilizing air bacteria circulating within the building. (Function) The function of the fluid sterilization device of this related invention, which is configured as a steamer, will be described below as a typical embodiment of the fluid sterilization method of the specific invention. When the fluid flowing through piping such as a horizontal horizontal pipe leading from the lower water tank of the cooling tower to the load section reaches the fluid reduction section,
The flow rate slows down and flows slowly. The fluid is sterilized by ultraviolet rays emitted from the ultraviolet germicidal lamp while the fluid is decelerated in this fluid deceleration section. The fluid thus sterilized is recycled to the load section. If multiple ultraviolet sterilizing lamps are removably arranged in the fluid deceleration section, sludge and the like will adhere to the ultraviolet sterilizing lamps due to long-term use, and if the sterilizing ability decreases, the circulation of cooling water will be stopped. During the process, remove the ultraviolet germicidal lamp from this reduction section and clean it or replace it with a new one. In addition, if the second UV germicidal lamp is arranged parallel to each other with a gap in the direction that crosses the flow direction of the fluid flowing through the piping system, the entire amount of the fluid flows around the germicidal lamp, and the ultraviolet rays sterilized by When the ultraviolet sterilizing lamps are arranged parallel to each other with gaps in the direction of the flow of the fluid flowing through the piping, the fluid flows along the ultraviolet sterilizing lamps without disturbing the flow of the fluid. and then sterilized. If a peacock for air removal is provided at the -L section of the fluid deceleration section, the air remaining in the fluid piping made of liquid and gathered inside the fluid deceleration section is removed from the peacock. The internal pressure of the evaporator section (when the liquid escapes to the outside) does not increase, and the liquid flows around the entire circumference of the ultraviolet germicidal lamp. In systems where the piping is closed to air conditioning ducts and this fluid reduction unit is placed downstream of the air filtration filter, radiant heat from lighting equipment is used to loosen the air and heat indoor buildings, factories, etc. In an air conditioning system in which most of the air is recirculated and little fresh air is introduced, after the filter removes dust and mold from the air, this air flow is decelerated by the fluid deceleration section. 5, flows slowly and undergoes sterilization treatment by ultraviolet light.

It is a horizontal horizontal pipe that spans the load section C and the load section C. This horizontally drawn pipe 10 is made of a straight pipe with a circular cross section, and a rectangular parallelepiped box with a large cross-sectional area is located in the middle of the second horizontally drawn pipe 10 ]-]
A fluid deceleration section consisting of a] 1 is formed on the same axis as the horizontal drawing pipe 1-0. The flow velocity within this fluid deceleration section 11 is approximately 1/2 of the flow velocity in the other horizontal drawing pipes 10. A plurality of ultraviolet germicidal lamps 2 are arranged parallel to each other at intervals in the box body 1a, which is the fluid deceleration section 11, so as to be removable from the outside. At this time, each ultraviolet germicidal lamp 12 is installed vertically from above in a posture that crosses the flow direction of the circulating cooling water flowing in the longitudinal direction inside the box 1]-a, from the top wall of 1a. It is suspended and supported by a socket. The ultraviolet germicidal lamps 1-2 may be arranged with their @ lines extending horizontally inward by shifting their positions from both side walls of the box body 1-1a and oriented in the opposite direction (Fig. 2). reference). Instead of this box body 11a, a cylindrical body 111) may be used (see FIG. 23). 1-3 is a peacock provided on the upper wall of the fluid deceleration section 11 for venting air. Second embodiment (see FIG. 4) If different from the eleventh embodiment, the ultraviolet germicidal lamp 12 is
The fluid deceleration portions are horizontally arranged inward from both ends of the cylindrical body 111) along the longitudinal direction thereof. These ultraviolet germicidal lamps 2 are spaced apart from each other. Otherwise, the same reference numerals as in the first embodiment have the same structure and function. Third Embodiment (See Figure 5) In this example, 20 is a central air conditioning system (see Figure 5).
(not shown), and this air duct 20
A filter 21 for air filtration is disposed inside, and a fluid speed reduction section 11 of the sterilizer is disposed between this filter 21 and the air blowout 1]22. - An ultraviolet germicidal lamp 12 is removably arranged inside. (Effects of the Invention) The effects of the fluid sterilization method, which is the specific invention, configured and operated as described above, are as follows. The velocity of the fluid to be sterilized is reduced in a fluid reduction section formed in a part of the piping, and sterilization is performed using ultraviolet light in this reduced state. A fluid flowing at a low speed can be efficiently sterilized by being irradiated with ultraviolet rays for a long time.The fluid sterilizer, which is a related invention, can carry out the fluid sterilization method of the specified invention, and the ultraviolet sterilizing lamp is installed inside the fluid deceleration section. Because it is removably installed in the deceleration section, if sludge in the fluid adheres to the outer surface of the UV germicidal lamp and the sterilizing ability decreases, the contaminated UV germicidal lamp can be removed from this reduction part and cleaned. There is no need to install a special wiper-type or brush-type cleaning device in the ultraviolet germicidal lamp. Fluid can be effectively sterilized without occupying the space inside the fluid reduction section with a cleaning device. The pipe has a circular cross section. In the fluid sterilizer of the related invention, in which the fluid deceleration part is a straight pipe and the fluid reduction part is the box or cylindrical body, ancillary devices such as flow control valves and flow switching valves are completely unnecessary, and the structure of the entire fluid sterilizer is improved. In addition to being simple, in the case of the box, the upper wall and both side walls are flat, so it is possible to stably provide the attachment/detachment means (for example, a socket) for attaching sterilizers, etc. to the fluid reduction part in the fluid reduction part. In addition, it is possible to stably install sterilization, etc., and it is also possible to install ultraviolet germicidal lamps of the same size in parallel in the fluid deceleration section. Compared to straight pipes, the tendency of fluid flowing into the pipe to become turbulent can be reduced, and the fluid can be dispersed within the cylindrical body and flowed at a low speed along its longitudinal direction. In the fluid sterilizer of the related invention, which is arranged in a fluid deceleration part in a horizontal position transverse to the flow direction, parallel to each other with a gap, the fluid contacts each fluid tag equally over the entire width of the fluid deceleration part, Because this contact is repeated, it is possible to take a sufficiently long time to sterilize the bacteria in the fluid, and to perform effective sterilization.Also, in a perpendicular position transverse to the flow direction of the fluid, the gaps are spaced parallel to each other. In the fluid sterilizing device of the related invention in which the ultraviolet sterilizing lamp is arranged inside the fluid decelerating part, the load applied to the connection part between the ultraviolet sterilizing lamp and the fluid decelerating part is smaller than that in the case where the piping is arranged in a horizontal position, and it is easy to attach and detach. The socket is small and sufficient, and can uniformly sterilize the fluid over the entire height of the fluid reduction section. In the sterilizer of the related invention in which the fluid is piped, the fluid is irradiated with ultraviolet rays while flowing along the entire length of the fluid deceleration section in the longitudinal direction, so that the fluid can be effectively sterilized without disturbing the flow of the fluid. In the fluid sterilizer of the related invention in which the fluid deceleration section is formed in the middle of the horizontal horizontal pipe leading from the lower water tank of the cooling tower to the load section, the cooling water is cooled by the latent heat of vaporization and temporarily collected in the lower water tank. After being sterilized in this fluid reduction section,
It can be supplied to the load section and prevent air pollution due to sterilization of diseases such as those caused by veterans' diseases. In the fluid sterilizer of the related invention, in which an air bleed peacock is attached to the upper part of the fluid deceleration part, the air contained in the cooling water flowing through the fluid deceleration part is released from the peacock to the outside, thereby preventing the fluid deceleration part from increasing in pressure. It can be prevented. In a fluid sterilizer of a related invention in which this piping is used as an air conditioning duct and the fluid reduction part is piped downstream of the air filtration filter, air circulating inside buildings, factories, etc. is passed through the filter to remove dirt and mold. After removing the particles, the air flow can be slowed down by the fluid reduction section for sterilization.
