大気に放出するなどの対応が必要であった。Adhesive growth of aquatic organisms in cooling sea channels can cause blockage and abnormal damage to heat exchanger tubes, abnormal clogging of strainers, and decreases in water flow due to the adhesion or their falling off and flowing. May cause problems in plant operation. Chlorine has traditionally been injected to prevent the growth of aquatic organisms. In particular, since chlorine is dangerous to transport and handle in high-pressure containers,
As described in Japanese Patent Publication No. 2-33582 and Japanese Patent Publication No. 54-40472, subzinc acid is generated from chlorine ions in seawater by electrolyzing seawater to prevent adhesion and fouling of aquatic organisms. However, when chlorine is injected into large amounts of cooling seawater for use in power generation plants, etc., the injection of chlorine tends to be avoided from the perspective of environmental conservation, as the wastewater seawater may have a negative impact on coastal ecosystems. be. For this reason, there is a need for an alternative to chlorine injection to prevent adhesion and fouling of aquatic organisms. As one attempt at this, Japanese Patent Application Laid-Open No. 53-85551 proposes to prevent aquatic organisms from adhering to a heat exchanger by intermittently replacing water in a cooling water system with ozone-containing gas. However, when draining water from the cooling water system, it is replaced with ozone/containing gas, which requires complicated switching operations such as stopping water supply to the system, limiting plant loads, and when discharging ozone-containing gas, ozone decomposition equipment It was necessary to take measures such as decomposing unreacted ozone and eliminating its toxicity before releasing it into the atmosphere.

域に紫外線を照射し。For this reason, there is a method that does not affect the environment, is simple, and has a high adhesion prevention effect that uses ultraviolet light. This utilizes the sterilizing effect of ultraviolet rays with wavelengths of 253.7 nm and 253.7 m, and irradiates ultraviolet rays to environmental areas where aquatic organisms are likely to adhere to and form.
照射部を水棲生物の生息に不適な環境としてしまうもの
である。This makes the irradiated area an environment unsuitable for aquatic organisms to live.

紫外線ランプの漏電を防ぐ必要があった。The ultraviolet rays used in the aquatic organisms adhesion prevention device have the property of only passing through special quartz glass, so the protective casing of the device must be made of hard, brittle quartz glass.
When the device is installed in seawater, leakage from the seal part,
Or, seawater or river water may flow into the protective casing due to damage caused by foreign objects in the water or biological collisions.
It was necessary to prevent leakage of the ultraviolet lamp.
発電プラントの復水器等の熱交換器は年々大容量化し、
これに伴い水棲生物付着防止面積も増加してきており、
有効な水棲生物防止の効果をあげるために、多数の紫外
線光源が必要となっている。The capacity of heat exchangers such as condensers in power generation plants is increasing year by year.
Along with this, the area where aquatic organisms are prevented from adhering has also increased.
Multiple sources of ultraviolet light are required for effective aquatic biocontrol.
各光源には海水、河川水等の冷却水のリークによる漏電
の問題がつきまとい、熱交換器を運転中に多数の光源を
保守管理する上での漏電対策が必要であった。Each light source is plagued with the problem of electrical leakage due to leakage of cooling water such as seawater or river water, and it is necessary to take measures against electrical leakage when maintaining and managing a large number of light sources while the heat exchanger is in operation.

光源の保守管理が容易となる。A leak detection device is installed to detect leakage of cooling water into the protective housing, and an output amplifier, a power supply breaker, and a monitor panel are installed between this leak detection device and the power source of the ultraviolet lamp. Since the power supply is cut off, the power supply to the ultraviolet lamp will be cut off if there is any leakage of cooling water into the protective housing. Therefore, leakage of the ultraviolet lamp or light source is prevented,
Maintenance and management of the light source becomes easier.

易にすることができる。At this time, a potential difference is applied between the electrodes, so a current flows. This flowing minute /I) current is detected and amplified by an output amplifier. This amplified output enters the power supply circuit breaker of the ultraviolet lamp power supply, and the power supply is cut off by the power supply circuit breaker. This can prevent electrical leakage accidents in the ultraviolet lamp. In addition, since the detection output is installed outside the heat exchanger and connected to a monitor panel that shows the status of each lamp, it is easy to determine which of the many UV lamps is leaking and needs to be repaired. This makes maintenance management easier.

止することができる。In addition, the voltage and current applied to the mesh-like copper wire installed on the surface of the protective casing are caused by foreign matter mixed in seawater or river water used as cooling water for the heat exchanger colliding with the protective casing. This makes it possible to notice the placement of the protective housing made of quartz glass. Since the copper wires are attached in a grid pattern, it is possible to prevent the quartz glass from scattering if a foreign object collides with the protective case and breaks it.
