Description

本発明は、受水槽に関する。特に、水蒸気を融雪屋根パネルに送り出すために設置したボイラーと共に使用する融雪屋根パネル用受水槽に関する。   The present invention relates to a water receiving tank. It is related with the water-receiving tank for snow-melting roof panels used with the boiler installed in order to send out water vapor | steam to a snow-melting roof panel especially.

受水槽とは、ビル、マンション、学校、病院等の一度に多量の水を使用する建物等で、水道局から水道管を通って送られてきた水を建物の近くに、一旦、貯めておくための容器のことである。出願人は、融雪機能付屋根パネル(特願2011−158376)を開発したが、この融雪機能付屋根パネルは、ボイラーを稼働して発生させた多量の水蒸気を、融雪屋根パネルに供給することにより、屋根上に積もった雪を、水蒸気の熱で融かす仕組みになっている(図3参照)。一度に多量の水(水蒸気)を使用する必要があるため、融雪屋根パネルを機能させるためには専用の受水槽が必要となる。   Receiving tanks are buildings, condominiums, schools, hospitals, etc. that use a large amount of water at once, and temporarily store the water sent through the water pipe from the Waterworks Bureau near the building. It is a container for. The applicant has developed a roof panel with a snow melting function (Japanese Patent Application No. 2011-158376), and this roof panel with a snow melting function supplies a large amount of water vapor generated by operating a boiler to the snow melting roof panel. The snow on the roof is melted with the heat of water vapor (see Fig. 3). Since a large amount of water (water vapor) needs to be used at one time, a dedicated water receiving tank is required to make the snow melting roof panel function.

ボイラーとは、燃料を燃焼させて得た熱を水に伝え、水蒸気や温水に換える熱交換装置を持った熱源機器のことである。出願人が開発した融雪屋根パネルは、ボイラーで温度140℃以上の多量の水蒸気を発生させて、融雪屋根パネル内部に供給し、循環させるものである。ボイラーで発生させた水蒸気が、融雪屋根パネルを通過して、戻り配管から戻ってくる時でも、温度90℃〜100℃程度(時には100℃以上)の高温状態になっているものと思われる。   A boiler is a heat source device having a heat exchange device that transfers heat obtained by burning fuel to water and converts it into water vapor or hot water. The snow melting roof panel developed by the applicant is a boiler that generates a large amount of water vapor at a temperature of 140 ° C. or higher and supplies it to the snow melting roof panel for circulation. Even when the water vapor generated by the boiler passes through the snow-melting roof panel and returns from the return pipe, it seems that the temperature is about 90 ° C. to 100 ° C. (sometimes over 100 ° C.).

受水槽には、受水槽の中の水位が一定の水位以下にならないように、ボールタップ等からなる水位調節機構が備えられており、この調節機構は、水に浮かべたボールタップの位置をセンサとして、水位が減少すると給水し、所定の水位になると給水を停止するようになっている。ところが、ボールタップは、温度が90℃〜100℃程度の熱水、もしくは、それ以上の温度の水蒸気が、戻り配管を通過して受水槽にそのまま戻ってくると、受水槽の中で発生する乱流によって水位が激しく上下するため、激しく上下してしまい、水位調節機構を果たさなくなるという問題があることが解った。即ち、通常の受水槽では、融雪屋根パネル用の受水槽としては使用することができないことが解った。   The water receiving tank is equipped with a water level adjusting mechanism composed of ball taps or the like so that the water level in the water receiving tank does not fall below a certain level, and this adjusting mechanism uses the position of the ball tap floating on the water as a sensor, When the water level decreases, water is supplied, and when the water level reaches a predetermined level, the water supply is stopped. However, in the ball tap, when hot water having a temperature of about 90 ° C. to 100 ° C. or steam having a temperature higher than that passes through the return pipe and returns to the water receiving tank as it is, turbulence generated in the water receiving tank. It was found that the water level fluctuates up and down violently, so that the water level fluctuates up and down and the water level adjustment mechanism cannot be fulfilled. That is, it was found that a normal water receiving tank cannot be used as a water receiving tank for a snow melting roof panel.

受水槽には、特許文献1の如く、内部に水位を調節するボールタップ等のような水位調節機構を備えた受水槽において、水位調節機構故障の際、部品交換作業時のために、水位調節機構の取り付け部を仕切る二枚の仕切り板等を設けることにより、受水槽が分離しているものが知られている。即ち、受水槽が二枚の仕切り板のようなもので分けられ、二枚の仕切り板を連通管で繋いで水の通路としている受水槽が知られている。通常は連通管のバルブが開いており、左右の層は同じ水位を保っているが、清掃時にはバルブを閉じて右側の層から清掃し、左側の層にある水を供給することにより断水しないようにするための二重構造である。要するに、受水槽内での乱流を防止するという技術的な思想は全く無いと言える。   In the water receiving tank having a water level adjusting mechanism such as a ball tap or the like for adjusting the water level inside the water receiving tank as in Patent Document 1, in the event of a water level adjusting mechanism failure, the water level adjusting mechanism is used for parts replacement work. It is known that the water receiving tank is separated by providing two partition plates or the like for partitioning the attachment portion. That is, a water receiving tank is known in which a water receiving tank is divided into two partition plates and the two partition plates are connected by a communication pipe to form a water passage. Normally, the valve of the communication pipe is open, and the left and right layers maintain the same water level, but when cleaning, close the valve and clean from the right layer, and supply water in the left layer so that water does not shut off This is a double structure. In short, it can be said that there is no technical idea to prevent turbulent flow in the water receiving tank.

かかる仕切り板等を受水槽に適用し設置すれば、仕切り板によって、受水槽全体に生じる乱流(ボールタップ等に悪影響を及ぼすような乱流)は抑制することができるかも知れないが、仕切り板が障壁となって、高温の熱水や水蒸気が有する熱エネルギーをスムーズに受水槽全体に拡散させることができず、せっかく受水槽に戻り配管から高温の熱水や水蒸気が入ってくるのにもかかわらず、この熱エネルギーを有効に利用することができず、非常に勿体ない話である。   If such a partition plate or the like is applied to a water receiving tank and installed, the partition plate may be able to suppress turbulent flow (turbulent flow that adversely affects the ball tap or the like) that occurs in the entire water receiving tank. As a barrier, the thermal energy of high-temperature hot water and water vapor cannot be smoothly diffused throughout the water receiving tank, and high-temperature hot water or water vapor enters the pipe from the piping. Regardless, this heat energy cannot be used effectively and is a very unfortunate story.

<Overall structure of water receiving tank for snow melting roof panel>
Hereinafter, the water-receiving tank 10 for snow melting roof panels which concerns on this invention is demonstrated in detail, referring drawings. FIG. 1 is a front view of a water receiving tank 10 for a snow melting roof panel. The snow melting roof panel water receiving tank 10 is separated into a right water receiving tank and a left water receiving tank by installing two partition plates near the center. The right-side water receiving tank is piped so that hot hot water or steam returns from the return pipe. A water intake port of a water absorption pump is installed in the left water receiving tank, and hot water (or water) stored in the water receiving tank is pumped up by the water absorption pump and sent to the boiler. An air vent is installed in the upper part of the right water receiving tank so that the pressure inside the water receiving tank can be made equal to the atmospheric pressure. Furthermore, the outside of the water-receiving tank 10 for snow melting roof panels according to the present invention is covered with a heat insulating material 60 in order to prevent heat radiation to the outside of the water-receiving tank, and is installed in the ground which is a freezing and antifreeze zone.

本明細書において、中央付近に設置された二枚の仕切り板は、説明し易いように、それぞれ、右仕切り板20、左仕切り板30と記載することにする。右仕切り板20と左仕切り板30との間には、右仕切り板20と左仕切り板30とを連結するとともに、熱水(あるいは温水)の通路となる連通管40が設置されている。そして、右仕切り板20に穿孔された穴50の一部と、右仕切り板20に穿孔された穴50の位置よりも低い位置に穿孔された左仕切り板30の穴50の一部とが連通管40で連結されている。さらに、連通管40が設置されていない穴50を通過して、右仕切り板20と左仕切り板30との間に、熱水(あるいは温水、使用開始時は水)が貯えられ、かつ、熱水(あるいは温水、使用開始時は水)が自由に出入りすることができるようになっている。   In the present specification, the two partition plates installed near the center are referred to as a right partition plate 20 and a left partition plate 30 for easy explanation. Between the right partition plate 20 and the left partition plate 30, the right partition plate 20 and the left partition plate 30 are connected, and a communication pipe 40 serving as a hot water (or hot water) passage is installed. A part of the hole 50 drilled in the right partition plate 20 communicates with a part of the hole 50 of the left partition plate 30 drilled at a position lower than the position of the hole 50 drilled in the right partition plate 20. They are connected by a tube 40. Further, hot water (or hot water, water at the start of use) is stored between the right partition plate 20 and the left partition plate 30 through the hole 50 where the communication pipe 40 is not installed, Water (or hot water, water at the start of use) can enter and exit freely.

融雪屋根パネル用受水槽10は、稼働開始時においては、図1で示した水位(Hと記載したレベル)となっている。融雪屋根パネルに送る水蒸気を発生させるボイラーに水(稼働時は温水)を供給するために、左側受水槽内に吸水ポンプの吸水口を設置している。融雪屋根パネルに水蒸気を供給している間(ボイラー稼働時)、融雪屋根パネル用受水槽10の水位は、図1の「M」と「H」の間にあるのが通常である。   The snow melting roof panel water receiving tank 10 is at the water level (level indicated as H) shown in FIG. 1 at the start of operation. In order to supply water (hot water during operation) to the boiler that generates water vapor to be sent to the snow melting roof panel, a water intake port of a water absorption pump is installed in the left water receiving tank. While water vapor is supplied to the snow melting roof panel (when the boiler is operating), the water level of the water receiving tank 10 for the snow melting roof panel is usually between “M” and “H” in FIG.

融雪屋根パネル用受水槽10の水位が下がって「M」と「L」との間になった場合は、右仕切り板20の中央部に穴50が穿孔されており、ポンプにより吸引された熱水の一部は、この穴50を通過して対流することができるようになっている。融雪屋根パネルに水蒸気を供給している間(ボイラー稼働時)に「L」まで水位が下がることは殆ど無いが、循環経路内で何らかの不具合(配管の水漏れ等)により、水位が「L」まで下がることもあり得る。かかる場合には、図1で示した水位(Lと記載したレベル)を維持管理するためにボールタップが設置されている。ボールタップによる水位調節機構によって、水位が「L」よりも下がった場合は、受水槽に水道水が供給されるようになっている。   When the water level of the snow melting roof panel receiving tank 10 falls between “M” and “L”, a hole 50 is perforated in the center of the right partition plate 20, and the heat sucked by the pump Part of the water can be convected through the hole 50. While water is supplied to the snow melting roof panel (when the boiler is operating), the water level rarely drops to “L”, but the water level is “L” due to some sort of malfunction in the circulation path (such as water leakage from the piping). Can go down. In such a case, a ball tap is installed to maintain and manage the water level (level indicated as L) shown in FIG. When the water level falls below “L” by the water level adjusting mechanism using the ball tap, tap water is supplied to the water receiving tank.

<融雪屋根パネル用受水槽の仕切り板>
図2は、本発明に係る融雪屋根パネル用受水槽10に使用される右仕切り板20、及び、左仕切り板30の側面図である。右仕切り板20、及び、左仕切り板30は、最上部(「H」よりも上)に連通管40が設置されない穴50、上部(通常の水位「H」と「M」の間)に連通管40が設置されている穴50、最下部(「N」以下:戻り配管から戻ってきた熱水が噴き出す箇所以下)に連通管40が設置されない穴50を有している。さらに、右仕切り板20は、中央部(「M」と「L」との間)に連通管40が設置されない穴50を有している。図2において、連通管40が設置される穴40は「やや縦長の楕円」で記載されており、連通管が設置されない穴40は「横長の楕円」で記載されている。それ以外の個所は仕切り板によって分離されており熱水(あるいは温水)が通過できないようになっている。
<Partition plate for water receiving tank for snow melting roof panel>
FIG. 2 is a side view of the right partition plate 20 and the left partition plate 30 used in the snow melting roof panel water receiving tank 10 according to the present invention. The right partition plate 20 and the left partition plate 30 communicate with the upper portion (above “H”) where the communication pipe 40 is not installed, and the upper portion (between the normal water levels “H” and “M”). The hole 50 in which the pipe 40 is installed, and the hole 50 in which the communication pipe 40 is not installed are provided in the lowermost part (below “N”: below the location where hot water returned from the return pipe is ejected). Further, the right partition plate 20 has a hole 50 in the center portion (between “M” and “L”) in which the communication pipe 40 is not installed. In FIG. 2, the hole 40 in which the communication pipe 40 is installed is described as “a slightly vertically long ellipse”, and the hole 40 in which the communication pipe is not installed is described as “a horizontally long ellipse”. Other parts are separated by a partition plate so that hot water (or hot water) cannot pass through.

図2から解るように、右仕切り板20、及び、左仕切り板30に設置された穴50の位置(特に高さ)や分布状態は微妙に異なっている。この微妙な違いが、本発明のポイントであるところの融雪屋根パネル用受水槽10内部に、熱水(あるいは水蒸気)の有する熱エネルギーを有効に利用するための好ましい熱水(または温水)の対流を発生させるメカニズムと大いに関連している。   As can be seen from FIG. 2, the positions (particularly height) and distribution states of the holes 50 installed in the right partition plate 20 and the left partition plate 30 are slightly different. This subtle difference is the preferred convection of hot water (or hot water) for effectively using the thermal energy of hot water (or steam) in the water receiving tank 10 for snow melting roof panels, which is the point of the present invention. It is highly related to the mechanism that generates

<融雪屋根パネル用受水槽における対流発生のメカニズム>
融雪屋根パネルを稼働する初期段階で、融雪屋根パネル用受水槽10には、図1で示した水位(Hと記載したレベル)となっている。融雪屋根パネル上に降り積もった雪を融雪する際は、融雪屋根パネルに水蒸気を供給するために、ボイラーを稼働させる。ボイラーを稼働させるために、左側受水槽内に設置した吸水口から、融雪屋根パネル用受水槽10に貯えられた水がポンプによって吸い上げられる。その結果、左側受水槽の水位が下がる。左側受水槽の水位が下がると、左側受水槽の水位よりも高い位置にある右側受水槽にある水が、右側受水槽から左側受水槽に流れやすいように傾斜している連通管40通過して、右側受水槽から水が左側受水槽に供給され左右受水槽のレベルが保たれる。
<Mechanism of convection generation in water receiving tank for snow melting roof panel>
In the initial stage of operating the snow melting roof panel, the water receiving tank 10 for the snow melting roof panel has the water level (level indicated as H) shown in FIG. When melting snow that has fallen on the snow melting roof panel, the boiler is operated to supply water vapor to the snow melting roof panel. In order to operate the boiler, the water stored in the water receiving tank 10 for the snow melting roof panel is sucked up by the pump from the water inlet provided in the left water receiving tank. As a result, the water level in the left receiving tank is lowered. When the water level of the left water receiving tank is lowered, the water in the right water receiving tank located higher than the water level of the left water receiving tank passes through the communication pipe 40 that is inclined so as to easily flow from the right water receiving tank to the left water receiving tank. The water is supplied from the right receiving tank to the left receiving tank, and the levels of the left and right receiving tanks are maintained.

融雪屋根パネルに水蒸気を供給するためにボイラーを稼働させて、水蒸気を供給すると、水蒸気は、融雪屋根パネルを通過して、最終的に戻り配管から融雪屋根パネル用受水槽10に、高温の熱水として、一部は水蒸気として戻ってくる。この熱水(一部は水蒸気)は高温であるため、融雪屋根パネル用受水槽10の右側受水槽には大きな乱流が生じる。そして、この乱流は、高温であるため、比重が軽く、右側受水槽の最上部まで吹き出し、次に左側受水槽に拡大し、融雪屋根パネル用受水槽10全体に拡がっていこうとするが、右仕切り板20があるため、乱流が融雪屋根パネル用受水槽10全体に拡大するのを制御することができる。   When a boiler is operated to supply water vapor to the snow melting roof panel and water vapor is supplied, the water vapor passes through the snow melting roof panel, and finally reaches the water receiving tank 10 for the snow melting roof panel from the return pipe. As water, part returns as water vapor. Since this hot water (partly water vapor) is hot, a large turbulent flow is generated in the right water receiving tank of the snow melting roof panel receiving tank 10. And since this turbulent flow is high temperature, the specific gravity is light, it blows out to the uppermost part of the right-side water receiving tank, then expands to the left-side water receiving tank, and tries to spread throughout the water-receiving tank 10 for snow melting roof panels Since there is the right partition plate 20, it is possible to control the turbulent flow expanding to the entire snow receiving roof panel receiving tank 10.

さらに、右仕切り板20と左仕切り板30との間には連通管40が設置されており、右側受水槽の上部に吹き出した熱水が、右仕切り板20に設置された複数の穴50から、右側受水槽から左側受水槽に流れやすいように傾斜している連通管40に流れ込むことで乱流が制御される(連通管40は右仕切り板20側よりも左仕切り板30側の方が低くなるように傾斜しており、高低差により逆流しないように工夫されている)。制御された流れは、右仕切り板20の穴50から、左仕切り板30の穴50に連結された連通管40を通過して左側受水槽の上部に流れ出す。このようにして、融雪屋根パネル用受水槽10の上部(「H」と「M」の間)に熱水の流れを発生させることができる。   Further, a communication pipe 40 is installed between the right partition plate 20 and the left partition plate 30, and hot water blown out to the upper part of the right water receiving tank is from a plurality of holes 50 installed in the right partition plate 20. The turbulent flow is controlled by flowing into the communication pipe 40 inclined so as to easily flow from the right water receiving tank to the left water receiving tank (the communication pipe 40 is more on the left partition plate 30 side than on the right partition plate 20 side). It is slanted so as to be low, and it is devised so that it does not flow backward due to the height difference). The controlled flow passes from the hole 50 of the right partition plate 20 through the communication pipe 40 connected to the hole 50 of the left partition plate 30 and flows out to the upper part of the left water receiving tank. Thus, the flow of hot water can be generated in the upper part (between “H” and “M”) of the water receiving tank 10 for snow melting roof panels.

融雪屋根パネル用受水槽10の最下部(「N」以下)は、温水が自由に通過できるようになっており、比重が軽い熱水が上昇した部分に温水を供給するために、融雪屋根パネル用受水槽10の左側受水槽から融雪屋根パネル用受水槽10の右側受水槽への流れが発生することになる。このようにして、戻り配管から融雪屋根パネル用受水槽10に戻ってきた、高温の熱水または水蒸気の有する熱エネルギーを、融雪屋根パネル用受水槽10全体に均等に拡散させるような好ましい対流を生じさせることができる。   The lowermost part ("N" or less) of the water receiving tank 10 for the snow melting roof panel is designed to allow hot water to freely pass through the snow melting roof panel in order to supply the hot water to the portion where hot water having a light specific gravity has risen. A flow from the left water receiving tank of the water receiving tank 10 to the right water receiving tank of the snow melting roof panel water receiving tank 10 is generated. Thus, a preferable convection that diffuses the thermal energy of hot hot water or water vapor that has returned from the return pipe to the snow melting roof panel water receiving tank 10 evenly throughout the snow melting roof panel water receiving tank 10 is obtained. Can be generated.

融雪屋根パネル用受水槽10全体に好ましい対流を生じさせるために、受水槽内部の圧力が上がり過ぎないようにするため、右側受水槽の上面には、エア抜きが設置されており、右側受水槽内部の圧力を大気圧と同じ気圧にできるようになっている。また、左仕切り板20の最上部の穴50と右仕切り板20の最上部上端の穴50(右仕切り板20の穴50の数は左仕切り板30の穴50の数よりも少ない。乱流を制御するためである。)によって、右側受水槽内部の圧力も大気圧と同じ気圧にできるようになっている。一方、融雪屋根パネル用受水槽10の水位が下がって「M」と「L」との間になった場合であっても、右仕切り板20の中央部に穴50が穿孔されており、ポンプにより引き寄せられた熱水の一部は、この穴50を通過して対流することができるようになっている。   In order to prevent a pressure inside the water receiving tank from excessively increasing in order to generate a favorable convection in the water receiving tank 10 for the snow melting roof panel, an air vent is installed on the upper surface of the right water receiving tank. The internal pressure can be set to the same atmospheric pressure. Further, the uppermost hole 50 of the left partition plate 20 and the uppermost hole 50 of the right partition plate 20 (the number of the holes 50 of the right partition plate 20 is smaller than the number of the holes 50 of the left partition plate 30). The pressure inside the right water receiving tank can be set to the same pressure as the atmospheric pressure. On the other hand, even when the water level of the water receiving tank 10 for the snow melting roof panel falls and becomes between “M” and “L”, the hole 50 is perforated in the center of the right partition plate 20, and the pump A part of the hot water drawn by the air can be convected through the hole 50.
