Description

本発明は蒸気技術に係り、乾き度調整装置及び乾き度調整方法に関する。   The present invention relates to steam technology, and relates to a dryness adjusting device and a dryness adjusting method.

水は沸点に達した後、水蒸気ガス（気相部分）と、水滴（液相部分）と、が混合した湿り蒸気となる。ここで、湿り蒸気に対する水蒸気ガスの質量比を、「乾き度」という。あるいは、乾き度は、潜熱の比エンタルピに対する、湿り蒸気の比エンタルピと飽和液の比エンタルピとの差の比、としても定義される。例えば、水蒸気ガスと、水滴と、が半分ずつ存在すれば、乾き度は０．５となる。また、水滴が存在せず、水蒸気ガスのみが存在する場合は、乾き度は１．０となる（例えば、特許文献１から３参照。）。   After the water reaches the boiling point, it becomes wet steam in which water vapor gas (gas phase portion) and water droplets (liquid phase portion) are mixed. Here, the mass ratio of the water vapor gas to the wet steam is referred to as “dryness”. Alternatively, dryness is also defined as the ratio of the difference between the specific enthalpy of wet steam and the specific enthalpy of saturated liquid to the specific enthalpy of latent heat. For example, if water vapor gas and water droplets are present in half, the dryness is 0.5. Moreover, when there is no water droplet and only water vapor gas is present, the dryness is 1.0 (see, for example, Patent Documents 1 to 3).

以下に本発明の実施の形態を説明する。以下の図面の記載において、同一又は類似の部分には同一又は類似の符号で表している。但し、図面は模式的なものである。したがって、具体的な寸法等は以下の説明を照らし合わせて判断するべきものである。また、図面相互間においても互いの寸法の関係や比率が異なる部分が含まれていることは勿論である。   Embodiments of the present invention will be described below. In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals. However, the drawings are schematic. Therefore, specific dimensions and the like should be determined in light of the following description. Moreover, it is a matter of course that portions having different dimensional relationships and ratios are included between the drawings.

（第１の実施の形態）
第１の実施の形態に係る乾き度調整装置は、湿り蒸気（飽和蒸気と、飽和液と、が合わさったもの）が流れる蒸気管１Ａ、１Ｂ、１Ｃと、湿り蒸気の温度（水の飽和温度）よりも低い温度の気体を蒸気に混合させる混合器１０と、を備える。蒸気管１Ａの下流に蒸気管１Ｂが接続されており、蒸気管１Ｂの下流に蒸気管１Ｃが接続されている。混合器１０は、蒸気管１Ａと１Ｂの間に設けられている。 (First embodiment)
The dryness adjusting apparatus according to the first embodiment includes steam pipes 1A, 1B and 1C through which wet steam (a mixture of saturated steam and saturated liquid) flows, and the temperature of the wet steam (water saturation temperature). And a mixer 10 that mixes a gas having a temperature lower than that of the vapor into the vapor. A steam pipe 1B is connected downstream of the steam pipe 1A, and a steam pipe 1C is connected downstream of the steam pipe 1B. The mixer 10 is provided between the steam pipes 1A and 1B.

図２に示すように、標準大気圧下においては、水は沸点（１００℃）に達した後、液滴としての水と、蒸気と、が混合し、共存態にある湿り蒸気となる。圧力が一定の場合、湿り蒸気は加熱及び冷却により潜熱が変化するため、飽和温度は一定となる。ここで、下記（１）で与えられるように、湿り蒸気全量に対する、飽和蒸気の質量比を、「乾き度」という。したがって、飽和蒸気の乾き度は１となり、飽和液の乾き度は０となる。
ｘ＝ｍvapor／（ｍvapor＋ｍwater） （１）
ｘは乾き度、ｍvaporは飽和蒸気の質量、ｍwaterは飽和液の質量を表す。 As shown in FIG. 2, under standard atmospheric pressure, water reaches a boiling point (100 ° C.), and then water as droplets and steam are mixed to form wet steam in a coexisting state. When the pressure is constant, since the latent heat of wet steam changes due to heating and cooling, the saturation temperature is constant. Here, as given in (1) below, the mass ratio of saturated steam to the total amount of wet steam is referred to as “dryness”. Therefore, the dryness of the saturated steam is 1, and the dryness of the saturated liquid is 0.
x = m vapor / (m vapor + m water ) (1)
x represents the degree of dryness, m vapor represents the mass of saturated vapor, and m water represents the mass of saturated liquid.

図１に示す混合器１０としては、Ｔ字管等の分岐管、及びノズル等が使用可能である。混合器１０は、乾き度が調整された湿り蒸気を必要とする場所の傍にあることが好ましいが、配置場所は特に限定されない。蒸気管１Ａを流れる湿り蒸気に混合される気体は、湿り蒸気の飽和温度で液化しない気体であり、空気又は窒素等の不凝縮ガスが使用可能である。水を含まない気体であってもよい。例えば、蒸気管１Ａ内の圧力が標準大気圧と等しい場合、蒸気管１Ａ内を流れる湿り蒸気の温度は１００℃であり、混合器１０から湿り蒸気に混合される気体の温度は１００℃未満である。   As the mixer 10 shown in FIG. 1, a branch pipe such as a T-shaped pipe, a nozzle, and the like can be used. Although it is preferable that the mixer 10 be near the place where the wet steam whose dryness is adjusted is required, the arrangement place is not particularly limited. The gas mixed with the wet steam flowing through the steam pipe 1A is a gas that does not liquefy at the saturation temperature of the wet steam, and non-condensable gas such as air or nitrogen can be used. It may be a gas that does not contain water. For example, when the pressure in the steam pipe 1A is equal to the standard atmospheric pressure, the temperature of the wet steam flowing in the steam pipe 1A is 100 ° C., and the temperature of the gas mixed into the wet steam from the mixer 10 is less than 100 ° C. is there.

湿り蒸気の温度よりも低い温度の気体を湿り蒸気に混合させると、温度の低い気体は湿り蒸気の状態を変化させ、湿り蒸気由来の微小液滴を核として液滴が成長する。液滴の成長に伴い、湿り蒸気の乾き度が低下する。また、湿り蒸気の乾き度の低下は、混合される気体の温度及び量に依存する。例えば、混合される気体の温度が低いほど、湿り蒸気の乾き度は低下する。また、混合される気体の量が多いほど、湿り蒸気の乾き度は低下する。   When a gas having a temperature lower than the temperature of the wet steam is mixed with the wet steam, the gas having a low temperature changes the state of the wet steam, and the droplet grows using the fine droplets derived from the wet steam as nuclei. As the droplet grows, the dryness of the wet steam decreases. In addition, the reduction in wet steam dryness depends on the temperature and amount of the gas being mixed. For example, the lower the temperature of the gas to be mixed, the lower the dryness of the wet steam. Also, the greater the amount of gas mixed, the lower the dryness of the wet steam.

混合器１０には、湿り蒸気に混合される気体が流れる管２が接続されている。管２には、湿り蒸気に混合される気体を加熱又は冷却して気体の温度を調整する温度調整装置３と、湿り蒸気に混合される気体の量を調整するバルブ等を備える流量調整装置４と、が設けられていてもよい。   Connected to the mixer 10 is a pipe 2 through which a gas mixed with wet steam flows. The pipe 2 includes a temperature adjusting device 3 that adjusts the temperature of the gas by heating or cooling the gas mixed with the wet steam, and a flow rate adjusting device 4 that includes a valve that adjusts the amount of the gas mixed with the wet steam. And may be provided.

乾き度調整装置は、湿り蒸気を加熱する加熱器２０をさらに備えていてもよい。加熱器２０は、蒸気管１Ｂに設けられていてもよいし、蒸気管１Ａに設けられていてもよい。加熱器２０が湿り蒸気を加熱することにより、湿り蒸気の乾き度が上昇する。   The dryness adjusting device may further include a heater 20 that heats the wet steam. The heater 20 may be provided in the steam pipe 1B, or may be provided in the steam pipe 1A. When the heater 20 heats the wet steam, the dryness of the wet steam increases.

蒸気管１Ｂと蒸気管１Ｃとの間には、混合器１０で気体を混合された湿り蒸気の乾き度を計測する乾き度計３０が設けられている。乾き度計３０には、制御装置４０が接続されている。乾き度計３０は、乾き度の計測値を、制御装置４０に伝送する。制御装置４０は、乾き度の計測値と、乾き度の目標値と、を比較する。   Between the steam pipe 1B and the steam pipe 1C, a dryness meter 30 for measuring the dryness of the wet steam mixed with the gas by the mixer 10 is provided. A controller 40 is connected to the dryness meter 30. The dryness meter 30 transmits a dryness measurement value to the control device 40. The control device 40 compares the measured dryness value with the target dryness value.

乾き度の計測値が、乾き度の目標値よりも高い場合、制御装置４０は、温度調整装置３を制御して、湿り蒸気に混合される気体を冷却する。あるいは、制御装置４０は、流量調整装置を制御して、湿り蒸気に混合される気体の量を増加させる。   When the measured value of the dryness is higher than the target value of the dryness, the control device 40 controls the temperature adjusting device 3 to cool the gas mixed with the wet steam. Alternatively, the control device 40 controls the flow rate adjusting device to increase the amount of gas mixed with the wet steam.

乾き度の計測値が、乾き度の目標値よりも低い場合、制御装置４０は、温度調整装置３を制御して、湿り蒸気に混合される気体を加熱する。あるいは、制御装置４０は、流量調整装置を制御して、湿り蒸気に混合される気体の量を減少させる。またあるいは、制御装置４０は、加熱器２０を制御して、湿り蒸気を加熱する。   When the measured value of the dryness is lower than the target value of the dryness, the control device 40 controls the temperature adjusting device 3 to heat the gas mixed with the wet steam. Alternatively, the control device 40 controls the flow rate adjusting device to reduce the amount of gas mixed with the wet steam. Alternatively, the control device 40 controls the heater 20 to heat the wet steam.

従来、湿り蒸気に常温市水等の液体水をノズルで注入して、湿り蒸気中に液滴を形成する方法が提案されている。しかし、湿り蒸気に液体水を注入すると、注入された液滴を核として、大きな液滴が成長する場合がある。大きな液滴は、蒸気管の内壁に付着して、波状流や環状流となって蒸気管内部を流れ、蒸気管内部に乾き度のムラが生じる場合がある。また、注入された液体そのものも、蒸気管の内壁に付着する場合がある。   Conventionally, a method of injecting liquid water such as room temperature city water into wet steam with a nozzle to form droplets in the wet steam has been proposed. However, when liquid water is injected into wet steam, a large droplet may grow using the injected droplet as a nucleus. Large droplets adhere to the inner wall of the steam pipe and flow inside the steam pipe as a wave-like flow or an annular flow, which may cause unevenness of dryness inside the steam pipe. Moreover, the injected liquid itself may adhere to the inner wall of the vapor pipe.

これに対し、第１の実施の形態に係る乾き度調整装置によれば、湿り蒸気の飽和温度よりも低い温度の気体を湿り蒸気に混合させるため、気体を混合したことにより生じる液滴は、液体水を混合したことにより生じる液滴よりも微小になる。そのため、湿り蒸気の乾き度を正確に調整することが可能になる。   On the other hand, according to the dryness adjusting apparatus according to the first embodiment, a gas having a temperature lower than the saturation temperature of the wet steam is mixed with the wet steam. It becomes finer than the droplet generated by mixing liquid water. Therefore, it becomes possible to accurately adjust the dryness of the wet steam.

（その他の実施の形態）
上記のように本発明を実施の形態によって記載したが、この開示の一部をなす記述及び図面はこの発明を限定するものであると理解するべきではない。この開示から当業者には様々な代替実施の形態、実施例及び運用技術が明らかになるはずである。例えば、混合器１０によって、水の飽和温度よりも低い飽和温度を有する液体を湿り蒸気に混合してもよい。この場合、混合器１０は、アトマイザーであってもよい。水の飽和温度よりも低い飽和温度を有する液体としては、エタノール及びメタノール等のアルコールが使用可能である。水の飽和温度よりも低い飽和温度（沸点）を有する液体は、湿り蒸気の温度では気体になるため、液滴形成のための核とならない。そのため、湿り蒸気由来の微小液滴を核として液滴が成長するため、液体水を混合したことにより生じる液滴よりも、形成される液滴が微小になる。また、湿り蒸気の温度よりも低い温度の気体、又は湿り蒸気の温度よりも低い飽和温度を有する液体が混合される湿り蒸気は、流れている必要はなく、チャンバ等に貯蔵されている湿り蒸気であってもよい。このように、本発明はここでは記載していない様々な実施の形態等を包含するということを理解すべきである。 (Other embodiments)
Although the present invention has been described by the embodiments as described above, it should not be understood that the description and drawings constituting a part of this disclosure limit the present invention. From this disclosure, various alternative embodiments, examples and operational techniques should be apparent to those skilled in the art. For example, the mixer 10 may mix a liquid having a saturation temperature lower than the saturation temperature of water with the wet steam. In this case, the mixer 10 may be an atomizer. As the liquid having a saturation temperature lower than the saturation temperature of water, alcohols such as ethanol and methanol can be used. A liquid having a saturation temperature (boiling point) lower than the saturation temperature of water becomes a gas at the temperature of wet steam, and thus does not serve as a nucleus for droplet formation. Therefore, since the droplet grows with the minute droplet derived from the wet steam as a nucleus, the formed droplet becomes smaller than the droplet generated by mixing the liquid water. Further, the wet steam mixed with the gas having a temperature lower than the temperature of the wet steam or the liquid having the saturation temperature lower than the temperature of the wet steam does not need to flow, and the wet steam stored in the chamber or the like is not necessary. It may be. Thus, it should be understood that the present invention includes various embodiments and the like not described herein.
