Description

本発明は、空気中に撒布された微細な水滴の蒸発潜熱を利用して、雰囲気温度の低下を促すための高圧水噴霧設備に関するものである。   The present invention relates to a high-pressure water spraying facility for promoting a decrease in ambient temperature using latent heat of vaporization of fine water droplets distributed in the air.

近年、６ＭＰａ前後に加圧した水を噴霧ノズルに送り、粒径が１０〜３０μｍの微細な水粒を、屋外の集客施設、もしくは大型機器などの発熱源が存在し得る建屋に撒布して、ミストの蒸散に伴う潜熱により、雰囲気温度を低下させることが行われている（例えば、特許文献１参照）。   In recent years, water pressurized to around 6 MPa is sent to a spray nozzle, and fine water droplets with a particle size of 10 to 30 μm are distributed in outdoor customer collection facilities or buildings where heat sources such as large equipment can exist, The atmospheric temperature is lowered by latent heat accompanying mist evaporation (see, for example, Patent Document 1).

図６、図７は従来の高圧水噴霧設備の一例であって、水槽１から水を得て加圧する高圧ポンプ２と、当該高圧ポンプ２の吐出口に取り付けた逆止弁３と、当該逆止弁３の出側に通水方向上流端が連なる送水管路４と、当該送水管路４に取り付けた複数の噴霧ノズル５と、高圧ポンプ２の吐出口に取り付けた安全弁６と、送水管路４の通水方向下流端に取り付けたエア抜２１とを備えている。   6 and 7 show an example of a conventional high-pressure water spraying equipment, in which a high-pressure pump 2 that obtains and pressurizes water from a water tank 1, a check valve 3 attached to a discharge port of the high-pressure pump 2, and the reverse A water supply line 4 having an upstream end in the water flow direction connected to the outlet side of the stop valve 3, a plurality of spray nozzles 5 attached to the water supply line 4, a safety valve 6 attached to the discharge port of the high-pressure pump 2, and a water supply pipe And an air vent 21 attached to the downstream end of the passage 4 in the water flow direction.

噴霧ノズル５は、噴霧孔７が穿設してあるハウジング８、高圧ポンプ２からの送出水の圧力に応じて作動する感圧逆止弁９、当該感圧逆止弁９を通過した送出水を旋回流とするための螺旋状の溝１０が外周面に形作られている駒１１、及び噴霧孔７とは反対側に位置するようにハウジング８に取り付けたフィルタ１２などによって構成されている。   The spray nozzle 5 includes a housing 8 in which a spray hole 7 is formed, a pressure-sensitive check valve 9 that operates in accordance with the pressure of the feed water from the high-pressure pump 2, and feed water that has passed through the pressure-sensitive check valve 9. A spiral groove 10 for making a swirl flow is constituted by a piece 11 formed on the outer peripheral surface, a filter 12 attached to the housing 8 so as to be located on the side opposite to the spray hole 7 and the like.

感圧逆止弁９は送出水遮断用の金属球１３とスプリング１４を要素とし、送水管路４の圧力が１ＭＰａを下回っている場合には送出水をハウジング８内へ流入させず、送水管路４の圧力が１ＭＰａを超えるとハウジング８内へ送出水を流入させる。   The pressure sensitive check valve 9 includes a metal ball 13 and a spring 14 for shutting off the feed water, and when the pressure in the water feed pipe 4 is less than 1 MPa, the feed water is not allowed to flow into the housing 8. When the pressure in the passage 4 exceeds 1 MPa, the feed water is caused to flow into the housing 8.

すなわち、高圧ポンプ２を起動させて、噴霧ノズル５の入口側における圧力が１ＭＰａになると感圧逆止弁９が開き、送出水の圧力上昇に応じて噴霧孔７からミストが撒布されはじめ、ミストの蒸散に伴う潜熱により、雰囲気温度が低下する。   That is, when the high-pressure pump 2 is started and the pressure on the inlet side of the spray nozzle 5 reaches 1 MPa, the pressure-sensitive check valve 9 opens, and mist begins to be distributed from the spray hole 7 in response to the pressure increase of the feed water. Due to the latent heat accompanying transpiration, the ambient temperature decreases.

この後、高圧ポンプ２を停止させると、圧力下降に応じてミストが撒布されなくなり、噴霧ノズル５の入側での圧力が１ＭＰａを下回ると感圧逆止弁９が閉じる。
特開２００６−１７７５７５号公報 Thereafter, when the high-pressure pump 2 is stopped, the mist is not distributed according to the pressure drop, and the pressure-sensitive check valve 9 is closed when the pressure on the inlet side of the spray nozzle 5 falls below 1 MPa.
JP 2006-177575 A

上述した高圧水噴霧設備においては、高圧ポンプ２の吐出流量は安定運転時の流量で選定されており、その起動後に送水管路４の圧力が初期圧力（０．２ＭＰａ）から６ＭＰａに達するのには、送水管路４（特に高圧ホース）の容積が膨張するため、図５の左側に破線で描くように若干の時間を要し、高圧ポンプ２を停止させた後、送水管路４の圧力が初期圧力に戻るのには、膨張した送水管路４（特に高圧ホース）に蓄えられた水が噴霧ノズル５より排出される動作を伴うために、図５の右側に破線で描くように若干の時間を要する。   In the high-pressure water spray equipment described above, the discharge flow rate of the high-pressure pump 2 is selected by the flow rate during stable operation, and the pressure of the water supply line 4 reaches 6 MPa from the initial pressure (0.2 MPa) after the start-up. Since the volume of the water supply line 4 (especially the high pressure hose) expands, it takes some time to draw the broken line on the left side of FIG. 5, and after the high pressure pump 2 is stopped, the pressure of the water supply line 4 In order to return to the initial pressure, since the water stored in the expanded water supply pipe 4 (particularly, the high-pressure hose) is discharged from the spray nozzle 5, a little as shown by the broken line on the right side of FIG. Takes time.

高圧ポンプ２の起動時に、送水管路４の圧力が１ＭＰａを少し上回った時点では、噴霧ノズル５の感圧逆止弁９は開くものの、噴霧孔７から噴出する水の圧力が低く量が少ないため、定格の噴霧状態とは異なりミスト状になって撒布されるのには至らず、高圧ポンプ２を停止させた後、送水管路４の圧力が１ＭＰａを下回る直前では、前記感圧逆止弁９が完全に閉じておらず、微小な量の水が流れる。   At the time of starting the high-pressure pump 2, when the pressure of the water supply line 4 slightly exceeds 1 MPa, the pressure-sensitive check valve 9 of the spray nozzle 5 is opened, but the pressure of the water ejected from the spray hole 7 is low and the amount is small. Therefore, unlike the rated spraying state, the mist is not distributed and the pressure sensitive check is immediately before the high pressure pump 2 is stopped and immediately before the pressure of the water supply line 4 falls below 1 MPa. The valve 9 is not completely closed, and a minute amount of water flows.

このため、高圧ポンプ２の起動時や停止時には、噴霧ノズル５から水が液滴として落下することなり、高圧ポンプ２を停止させた後も、送水管路４の圧力が完全に１ＭＰａを下回らないうちは、水の滴下が収まらない。   For this reason, when the high-pressure pump 2 is started or stopped, water drops from the spray nozzle 5 as droplets, and even after the high-pressure pump 2 is stopped, the pressure in the water supply line 4 does not fall below 1 MPa completely. We ca n’t stop dripping water.

本発明は、設備の起動時及び停止時に、噴霧ノズルからの水の滴下を抑止できるようにすることを目的としている。   An object of the present invention is to be able to suppress dripping of water from a spray nozzle at the time of starting and stopping of equipment.

When water flows into the water supply line instantaneously and raises the pressure of the water supply line, and when the mist distribution is completed, if the first valve is closed and the second valve is opened, the expanded water supply line Return water from the water pipe due to contraction is instantaneously absorbed by the expansion tank, and the pressure of the water pipe decreases.

Return the feed water to the water supply line using the pressure control valve.

To do.

The air vent 21 is attached to the downstream end of the water flow direction 4, and the pressurizing tank ET 1 plays a role as an accumulator that can store the pressure of the water discharged from the high-pressure pump 2.

水を加圧して送出する高圧ポンプ２の吸引口に給水管路１６を接続し、安全弁６と逆止弁３を直列に組み込んだ基幹管路２４の入側を高圧ポンプ２の吐出口に接続し、撒布系統Ｌ１の送水管路４の上流端を基幹管路２４の出側に接続し、撒布系統Ｌ１のバイパス管路１５の他端を戻り管路２３を介して給水管路１６に接続している。   The water supply line 16 is connected to the suction port of the high-pressure pump 2 that pressurizes and delivers water, and the inlet side of the main line 24 that incorporates the safety valve 6 and the check valve 3 in series is connected to the discharge port of the high-pressure pump 2. Then, the upstream end of the water supply line 4 of the distribution system L1 is connected to the outlet side of the trunk line 24, and the other end of the bypass line 15 of the distribution system L1 is connected to the water supply line 16 via the return line 23. is doing.

前記撒布系統Ｌ１は、高圧ポンプ２、第１のバルブSV１、及び第２のバルブSV２を操作するためのコントローラ１７を有し、このコントローラ１７は、一定温度以下、あるいは一定湿度以上で高圧ポンプ２を停止する機能、並びにタイマによってスケジュール運転を行う機能を具備している。   The distribution system L1 has a controller 17 for operating the high-pressure pump 2, the first valve SV1, and the second valve SV2. The controller 17 is a high-pressure pump 2 at a certain temperature or below or above a certain humidity. And a function for performing a scheduled operation with a timer.

更に、前記戻り管路２３に、送水管路４からの戻り水の圧力を吸収し得るアキュムレータとしての膨張タンクET２を連通させ、給水管路１６の通水方向上流端に低圧配管保護用の逆止弁１８を介して水道配管１９を接続している。   Further, an expansion tank ET2 serving as an accumulator capable of absorbing the pressure of the return water from the water supply pipe 4 is connected to the return pipe 23, and the reverse end for protecting the low pressure pipe is connected to the upstream end of the water supply pipe 16 in the water flow direction. A water pipe 19 is connected via a stop valve 18.

コントローラ１７は、ミストの撒布を開始するのに際しては、図２の左側に描くように第２のバルブSV２に対する閉止指令を送信した直後に、高圧ポンプ２の起動指令と第１のバルブSV１に対する開放指令とを同時に発信し、ミストの撒布を完了するのに際しては、図２の右側に描くように第１のバルブSV１に対する閉止指令を送信した直後に、高圧ポンプ２の停止指令と第２のバルブSV２に対する開放指令とを同時に発信する。   When starting the mist distribution, the controller 17 immediately after sending the closing command for the second valve SV2 as depicted on the left side of FIG. 2, the start command for the high-pressure pump 2 and the opening for the first valve SV1. When the command is simultaneously transmitted and the mist distribution is completed, the stop command for the high-pressure pump 2 and the second valve are immediately transmitted after the close command for the first valve SV1 is transmitted as depicted on the right side of FIG. The release command for SV2 is sent simultaneously.

高圧水噴霧設備の当初始動時には、送水管路４、並びに与圧タンクET１のいずれも内部の水圧が高くなっていないので、噴霧ノズル５から滴下する水を回収する手段を仮設しておき、第２のバルブSV２を閉止し且つ第１のバルブSV１を開放した状態で、高圧ポンプ２を起動させて送出水を送水管路４に行き渡らせ、噴霧ノズル５から定格状態のミスト撒布を行い、送水管路４、並びに与圧タンクET１の内部を６ＭＰａ前後に加圧する。つまり、設備の当初始動時は、与圧タンクET１の内圧が高くないので、噴霧ノズル５から滴下する水を回収するための手段を用意する必要があるものの、上述したような手立てにより与圧タンクET１の内部が加圧されれば、噴霧ノズル５からの水の滴下を抑えることができる。   At the initial startup of the high-pressure water spraying facility, the water pressure in the water supply pipe 4 and the pressurized tank ET1 is not high, so a means for collecting the water dripping from the spray nozzle 5 is temporarily installed. 2 with the valve SV2 closed and the first valve SV1 opened, the high-pressure pump 2 is started to spread the water to be delivered to the water supply line 4, and the spray nozzle 5 performs the mist distribution in the rated state, The water pipe 4 and the inside of the pressurized tank ET1 are pressurized to around 6 MPa. That is, when the equipment is initially started, since the internal pressure of the pressurized tank ET1 is not high, it is necessary to prepare a means for collecting water dripped from the spray nozzle 5, but the pressurized tank is prepared by the above-described method. If the inside of ET1 is pressurized, dripping of water from the spray nozzle 5 can be suppressed.

次いで、送水管路４、並びに与圧タンクET１の内部が６ＭＰａ前後に加圧された状態で、第１のバルブSV１を閉止して、送水管路４と同程度の圧力を与圧タンクET１に封じ込め、その後、高圧ポンプ２を停止させると同時に第２のバルブSV２を開放して、送水管路４の内部の圧力が急激に下がるように、送水管路４からある程度の水量（高圧ポンプ２の定格圧力と噴霧ノズル５の感圧逆止弁９の設定圧力と差分圧に見合う送水管路４内の水量）を膨張タンクET２内へ逃がし、待機状態とする。   Next, in a state where the inside of the water supply pipe 4 and the pressurized tank ET1 is pressurized to around 6 MPa, the first valve SV1 is closed, and a pressure similar to that of the water supply pipe 4 is applied to the pressurized tank ET1. After the containment, the high-pressure pump 2 is stopped and the second valve SV2 is opened at the same time, so that a certain amount of water (from the high-pressure pump 2 is removed) so that the pressure inside the water supply line 4 drops rapidly. The rated pressure and the set pressure of the pressure-sensitive check valve 9 of the spray nozzle 5 and the amount of water in the water supply conduit 4 corresponding to the differential pressure) are allowed to escape into the expansion tank ET2 and enter a standby state.

高圧水噴霧設備の実運用に際し、第２のバルブSV２を閉止した後、高圧ポンプ２を起動させるのと同時に、第１のバルブSV１を開放すると、既に与圧タンクET１に蓄えられている送出水の６ＭＰａ前後の圧力が、図５の左側に実線で描くように瞬時に送水管路４に働き、感圧逆止弁９（図７参照）が開くのと同時に噴霧ノズル５からミストが撒布されはじめ、これにより、ミスト撒布開始時の水の滴下を抑止でき、しかも、与圧タンクET１はアキュムレータの機能を兼ねて、高圧ポンプ２の脈動を和らげる役割を担う。   In actual operation of the high-pressure water spraying facility, after the second valve SV2 is closed, the high-pressure pump 2 is started, and at the same time the first valve SV1 is opened, the water already stored in the pressurized tank ET1 The pressure of around 6 MPa immediately acts on the water supply line 4 as depicted by the solid line on the left side of FIG. 5, and at the same time the pressure sensitive check valve 9 (see FIG. 7) opens, mist is distributed from the spray nozzle 5. Initially, this makes it possible to suppress dripping of water at the start of mist distribution, and the pressurized tank ET1 also serves as an accumulator and plays a role of reducing the pulsation of the high-pressure pump 2.

また、第１のバルブSV１を閉止したうえ、高圧ポンプ２を停止させるのと同時に、第２のバルブSV２を開放すると、送水管路４からある程度の水量が膨張タンクET２内へ逃げることによって、送水管路４からの戻り水の圧力が、図５の右側に実線で描くように瞬時に膨張タンクET２に吸収され、感圧逆止弁９（図７参照）が閉じ、これにより、ミスト撒布完了時の水の滴下を抑止できる。   Further, when the first valve SV1 is closed and the high pressure pump 2 is stopped simultaneously with the opening of the second valve SV2, a certain amount of water escapes from the water supply pipe 4 into the expansion tank ET2. The pressure of the return water from the water pipeline 4 is instantaneously absorbed by the expansion tank ET2 as depicted by the solid line on the right side of FIG. 5, and the pressure-sensitive check valve 9 (see FIG. 7) is closed, thereby completing the mist distribution. The dripping of water at the time can be suppressed.

これに加えて、給水管路１６と水道配管１９との間に逆止弁１８を介在させてあるので、水道配管１９が送水管路４からの戻り水の影響を受けない。   In addition, since the check valve 18 is interposed between the water supply pipe 16 and the water supply pipe 19, the water supply pipe 19 is not affected by the return water from the water supply pipe 4.

図３、図４は本発明の高圧水噴霧設備の第２の例であって、図中、図１、図２と同一の符号を付した部分は同一物を表している。   3 and 4 show a second example of the high-pressure water spray equipment of the present invention. In the figure, the same reference numerals as those in FIGS. 1 and 2 denote the same parts.

送水管路４、噴霧ノズル５、第１のバルブSV１、与圧タンクET１、バイパス管路１５、及び第２のバルブSV２を要素とする複数の撒布系統Ｌ２，Ｌ３，…Ｌｎを有し、基幹管路２４と各撒布系統Ｌ２，Ｌ３，…Ｌｎを形成している送水管路４の送水方向上流端との間に、それぞれ第３のバルブSV３を介在させている。   It has a plurality of distribution systems L2, L3,... Ln, each of which includes a water supply line 4, a spray nozzle 5, a first valve SV1, a pressurized tank ET1, a bypass line 15, and a second valve SV2. A third valve SV3 is interposed between the pipe 24 and the upstream end in the water supply direction of the water supply pipe 4 forming the distribution systems L2, L3,.

撒布系統Ｌ２，Ｌ３，…Ｌｎは、高圧ポンプ２、第１のバルブSV１、第２のバルブSV２、及び第３のバルブSV３を操作するためのコントローラ２０を有し、このコントローラ２０は、一定温度以下、あるいは一定湿度以上で第３のバルブSV３を閉止する機能、並びにタイマによってスケジュール運転を行う機能を具備している。   The distribution system L2, L3,... Ln has a controller 20 for operating the high-pressure pump 2, the first valve SV1, the second valve SV2, and the third valve SV3. Below, or a function of closing the third valve SV3 at a certain humidity or higher, and a function of performing a scheduled operation by a timer are provided.

逆止弁３の出側と戻り管路２３との間に圧力調整弁Ｖを介在させ、当該戻り管路２３の撒布系統Ｌ２から離れた他の撒布系統Ｌｎ付近にも、別の膨張タンクET２を連通させている。   A pressure regulating valve V is interposed between the outlet side of the check valve 3 and the return line 23, and another expansion tank ET2 is also provided in the vicinity of another distribution system Ln away from the distribution system L2 of the return line 23. Is in communication.

コントローラ２０は、ミストの撒布を開始するのに際しては、図４の左側に描くように第２のバルブSV２に対する閉止指令を送信した直後に、第１のバルブSV１に対する開放指令、及び第３のバルブSV３に対する開放指令を同時に発信し、ミストの撒布を完了するのに際しては、図４の右側に描くように第１のバルブSV１に対する閉止指令を送信した直後に、第２のバルブSV２に対する開放指令、及び第３のバルブSV３に対する閉止指令を同時に発信する。また、各コントローラ２０からの信号を受け、全ての撒布系統Ｌ２，Ｌ３，…Ｌｎによるミストの撒布が完了したときに高圧ポンプ２を停止させるコントローラ２２が別に設けてある。   When starting the mist distribution, the controller 20 immediately after sending the closing command for the second valve SV2 as depicted on the left side of FIG. 4, the opening command for the first valve SV1 and the third valve When the release command for the SV3 is simultaneously transmitted and the mist distribution is completed, immediately after the close command for the first valve SV1 is transmitted as illustrated on the right side of FIG. 4, the release command for the second valve SV2, And a closing command for the third valve SV3 is simultaneously transmitted. Further, a controller 22 for stopping the high-pressure pump 2 when receiving a signal from each controller 20 and completing the mist distribution by all the distribution systems L2, L3,... Ln is provided.

高圧水噴霧設備の実運用にあたっては、ミストの撒布時と同様に撒布系統Ｌ２，Ｌ３，…Ｌｎのうちのいずれかの第２のバルブSV２を閉止し且つ第１のバルブSV１、第３のバルブSV３を開放させ、与圧タンクET１に蓄えられた水を送水管路４に送るとともに、高圧ポンプ２からの送出水を送水管路４に行き渡らせる。   In actual operation of the high-pressure water spraying facility, the second valve SV2 of any one of the distribution systems L2, L3,... Ln is closed, and the first valve SV1 and the third valve are the same as when the mist is distributed. The SV 3 is opened, the water stored in the pressurized tank ET1 is sent to the water supply line 4, and the water supplied from the high-pressure pump 2 is distributed to the water supply line 4.

次いで、第１のバルブSV１を閉止して、６ＭＰａ前後に加圧された送出水の圧力を与圧タンクET１に蓄え、第２のバルブSV２を開放し且つ第３のバルブSV３を閉止して待機状態とする。   Next, the first valve SV1 is closed, the pressure of the feed water pressurized to around 6 MPa is stored in the pressurized tank ET1, the second valve SV2 is opened, and the third valve SV3 is closed to stand by. State.

ミストを撒布すべき撒布系統Ｌ２，Ｌ３，…Ｌｎのうちのいずれかの第２のバルブSV２を閉止した後、その同じ系統の第１のバルブSV１、第３のバルブSV３を開放すると、既に与圧タンクET１に蓄えられている送出水の６ＭＰａ前後の圧力が、図５の左側に実線で描くように瞬時に送水管路４に働き、感圧逆止弁９（図７参照）が開くのと同時に噴霧ノズル５からミストが撒布されはじめ、これにより、ミスト撒布開始時の水の滴下を抑止でき、しかも、与圧タンクET１はアキュムレータの機能を兼ねて、高圧ポンプ２の脈動を和らげる役割を担う。   After closing the second valve SV2 of any of the distribution systems L2, L3,... Ln to which mist is to be distributed, if the first valve SV1 and the third valve SV3 of the same system are opened, it is already given. The pressure of about 6 MPa of the delivery water stored in the pressure tank ET1 is instantaneously applied to the water delivery pipeline 4 as shown by the solid line on the left side of FIG. 5, and the pressure-sensitive check valve 9 (see FIG. 7) opens. At the same time, mist starts to be sprayed from the spray nozzle 5, thereby preventing dripping of water at the start of mist spraying, and the pressurized tank ET 1 also serves as an accumulator and serves to moderate the pulsation of the high-pressure pump 2. Bear.

また、ある系統の第１のバルブSV１を閉止したうえ、第２のバルブSV２を開放し且つ第３のバルブSV３を閉止すると、送水管路４からの戻り水の圧力が、図５の右側に実線で描くように瞬時に膨張タンクET２に吸収され、感圧逆止弁９（図７参照）が閉じ、これにより、ミスト撒布完了時の水の滴下を抑止できる。   Further, when the first valve SV1 of a certain system is closed, the second valve SV2 is opened, and the third valve SV3 is closed, the pressure of the return water from the water supply pipe 4 is shown on the right side of FIG. As depicted by the solid line, the pressure is immediately absorbed in the expansion tank ET2, and the pressure-sensitive check valve 9 (see FIG. 7) is closed, thereby preventing dripping of water when the mist distribution is completed.

複数の撒布系統Ｌ２，Ｌ３，…Ｌｎを形成した場合、そのいずれかがミストを撒布していれば、高圧ポンプ２は継続運転されることになる。   When a plurality of distribution systems L2, L3,... Ln are formed, if any of them distributes mist, the high-pressure pump 2 is continuously operated.

稼動状態の撒布系統Ｌ２，Ｌ３，…Ｌｎが減り、高圧ポンプ２の送出水が過剰になると、当該送出水は、圧力調整弁Ｖを経て給水管路１６へ戻され、全ての撒布系統Ｌ２，Ｌ３，…Ｌｎによるミストの撒布が完了したときには高圧ポンプ２が停止する。   When the distribution system L2, L3,... Ln in the operating state decreases and the high-pressure pump 2 discharge water becomes excessive, the discharge water is returned to the water supply pipe 16 via the pressure regulating valve V, and all the distribution lines L2, L2 When the mist distribution by L3,... Ln is completed, the high pressure pump 2 is stopped.

また、膨張タンクET２が戻り管路２３の適宜離れた個所にあるので、送水管路４からバイパス管路１５を経てくる戻り水の圧力を、撒布系統Ｌ２，Ｌ３，…Ｌｎに対し、圧力伝搬に有利な近場で瞬時に吸収でき、ミスト撒布完了時に噴霧ノズル５から水が滴下することを確実に防げる。   Further, since the expansion tank ET2 is located at an appropriate distance from the return pipe 23, the pressure of the return water passing through the bypass pipe 15 from the water supply pipe 4 is transmitted to the distribution systems L2, L3,. It is possible to absorb instantly in the near field advantageous to the water, and reliably prevent water from dripping from the spray nozzle 5 when the mist distribution is completed.
