To pass through the filtration membrane to purify rainwater and use the water head to pump water to the elevated water tank.
For example, when rainwater stops, the head of the purified water is passed through the filtration membrane from the opposite direction to clean the filtration membrane, for example, to eliminate clogging.
前記高層建築物の雨水濾過装置によれば、雨水の水頭に
より揚水が行われるので、揚水ポンプが不要になる。According to the rainwater filtering device for a high-rise building, since pumping is performed by the head of rainwater, a pump for pumping water is unnecessary.
又、清浄化した水により濾過膜の目づまりが解消される
ので、濾過膜洗浄のための作業が不要になる。Further, since the purified water eliminates the clogging of the filtration membrane, the work for cleaning the filtration membrane becomes unnecessary.
以下、図面を参照して本発明を適用した高層建築物の雨
水濾過装置の一実施例を説明する。Hereinafter, an embodiment of a rainwater filter for a high-rise building to which the present invention is applied will be described with reference to the drawings.
なお、第１図は高層建築物の雨水濾過装置の系統図であ
り、先ず全体の構成について説明する。Note that FIG. 1 is a systematic diagram of a rainwater filtering device for a high-rise building, and the overall configuration will be described first.
Ａは高層建築物であり、その屋根面１の雨水は集水され
て雨水管２に流入するように構成されている。雨水管２
は、雨水を濾過する際の圧力容器（ベッセル）となるも
のであり、その下端には雨水の水量、水質に応じて排水
量を調整する流量調整弁３と排水を貯溜する排水槽４と
が設けられている。A is a high-rise building, and the rainwater on the roof surface 1 is collected and flows into the rainwater pipe 2. Rainwater pipe 2
Is a pressure vessel (vessel) for filtering rainwater, and a lower end thereof is provided with a flow rate adjusting valve 3 for adjusting the amount of drainage according to the amount of rainwater and the quality of water, and a drain tank 4 for storing drainage. Has been.
雨水管２の内部には、下端部に精密濾過膜５を設けた濾
過水管６が配置され、雨水管２内の雨水は濾過水管６の
下端の精密濾過膜５の部分を透過し、換言すれば膜５で
濾過されて濾過水管６に浸出するように構成されてい
る。Inside the rainwater pipe 2, a filtered water pipe 6 provided with a microfiltration membrane 5 at the lower end is arranged, and the rainwater in the rainwater pipe 2 permeates the microfiltration membrane 5 at the lower end of the filtered water pipe 6, in other words, the membrane. It is configured to be filtered at 5 and to leach into the filtered water pipe 6.
７は精密濾過膜５を透過した濾過水を貯溜する濾過水
槽、８は濾過水供給ポンプであり、濾過水を高層階に圧
送するためのものである。溢流水管９は濾過水槽７の有
効容量を越えた部分の濾過水を下層階の溢流水層１０に
流下させるものである。Reference numeral 7 is a filtered water tank for storing the filtered water that has permeated the microfiltration membrane 5, and 8 is a filtered water supply pump for pumping the filtered water to the higher floors. The overflow water pipe 9 causes the filtered water in a portion exceeding the effective capacity of the filtered water tank 7 to flow down to the overflow water layer 10 on the lower floor.
次に、雨水濾過装置の作用を説明する。Next, the operation of the rainwater filter will be described.
雨が降り始めると、屋根面１によって雨水が集水され、
雨水管２内に流れ込んで流下する。雨水の一部分は、雨
水量等を勘案して適度に調整された流量調整弁３を通過
し、排水槽４に貯溜される。When it starts to rain, the roof surface 1 collects rainwater,
It flows into the rainwater pipe 2 and flows down. Part of the rainwater passes through the flow rate adjusting valve 3 that is appropriately adjusted in consideration of the amount of rainwater and the like, and is stored in the drainage tank 4.
一方、雨水管２内に流れこんだ雨水は精密濾過膜５の外
側から内側方向に透過し、濾過水Ｗが濾過水管６内に浸
出するようになる。そして、降雨の継続により雨水が増
量すれば雨水管２中の水位も上り、それにつれて濾過水
管６内の水位も次第に上昇する。雨水管２中の水深がｈ
１になると、精密濾過膜５によって不純物が除去、分離
された濾過水Ｗの水位が濾過水管６の上部に達し、濾過
水槽７に流れ込んで貯溜される。On the other hand, the rainwater that has flowed into the rainwater pipe 2 permeates from the outer side to the inner side of the microfiltration membrane 5, and the filtered water W comes into the filtered water pipe 6. When the amount of rainwater increases due to continued rainfall, the water level in the rainwater pipe 2 also rises, and the water level in the filtered water pipe 6 gradually rises accordingly. The water depth in the rainwater pipe 2 is h
When it becomes 1 , the impurities are removed by the microfiltration membrane 5 and the separated water level of the filtered water W reaches the upper part of the filtered water pipe 6, flows into the filtered water tank 7, and is stored therein.
即ち、濾過水Ｗは、水深ｈ１によって決定される水頭に
より、自動的に濾過水槽７にまで揚水されることにな
る。That is, the filtered water W is automatically pumped up to the filtered water tank 7 by the head determined by the water depth h 1 .
この際、濾過水槽７の有効容量を越えた部分の濾過水Ｗ
は、溢流水管９を流下して下層階に設けられた溢流水槽
１０に貯溜される。なお、濾過水Ｗの利用については、
濾過水槽７の設置階より高い階には濾過水供給ポンプ８
により圧送し、低い階には重力給水を行うことができ
る。At this time, the filtered water W of the portion exceeding the effective capacity of the filtered water tank 7
Is stored in the overflow water tank 10 provided on the lower floor by flowing down the overflow water pipe 9. Regarding the use of filtered water W,
A filtered water supply pump 8 is provided on a floor higher than the floor on which the filtered water tank 7 is installed.
It can be pumped by gravity and gravity water can be supplied to lower floors.
次に、精密濾過膜５の洗浄について説明する。Next, the cleaning of the microfiltration membrane 5 will be described.
雨が降り止んだ後、流量調整弁３を開放すると、雨水管
２内の雨水の水位と濾過水管６内の濾過水Ｗの水深がと
もに低下し、濾過水管６内の濾過水Ｗが増水時とは逆方

管２内に流れるようになる。この逆流によって、精密濾
過膜５の目づまりが解消され、自動洗浄が行われること
になる。洗浄排水は、流量調整弁３を通過して排水槽４
に貯溜される。When the flow rate adjusting valve 3 is opened after the rain stops, both the water level of the rainwater in the rainwater pipe 2 and the depth of the filtered water W in the filtered water pipe 6 decrease, and when the filtered water W in the filtered water pipe 6 increases. Flows in the opposite direction, in other words, from the inside of the microfiltration membrane 5 to the outside, that is, into the rainwater pipe 2. Due to this backflow, the clogging of the microfiltration membrane 5 is eliminated, and automatic cleaning is performed. The cleaning drainage passes through the flow rate adjusting valve 3 and drainage tank 4
Is stored in.
以上の如く、本実施例にかかる雨水濾過装置は、濾過水
Ｗの自動揚水と濾過膜の自動洗浄とを行い得る。As described above, the rainwater filter according to the present embodiment can perform automatic pumping of the filtered water W and automatic cleaning of the filter membrane.
なお、前記した水深ｈ１は濾過水槽７の設置高さ、雨水
管２、濾過水管６の容量等により変化するものであり、
図示の高さに限定されるものではない。The water depth h 1 changes depending on the installation height of the filtered water tank 7, the capacity of the rainwater pipe 2, the filtered water pipe 6, and the like,
It is not limited to the height shown.
以上説明したように、本発明に係る高層建築物における
雨水濾過装置は、雨水の水頭により濾過膜を透過させて
清浄な濾過水を得るとともに、水頭を利用して濾過水槽
に揚水するものであるから、揚水のための動力設備が不
要になる。As described above, the rainwater filtering device in a high-rise building according to the present invention is one that permeates the filtration membrane by the head of rainwater to obtain clean filtered water and pumps water to the filtered water tank using the head. Therefore, no power equipment for pumping is required.
更に、雨水の水頭低下時には、濾過水の水頭を利用して
濾過膜に逆透過させることにより、濾過膜の自動洗浄が
行われるので、洗浄のための給水停止を行う必要がな
く、また洗浄のための人手も不要になる。Furthermore, when the head of rainwater drops, the filtration membrane is reversely permeated by using the head of the filtration water, so that the filtration membrane is automatically cleaned, so there is no need to stop the water supply for cleaning, and No need for labor.
