Description
本発明は、気体管路内を蒸気や圧縮空気や各種ガス等が流下する場合に、混入している復水や凝縮水等の液体を分離する気液分離器に関する。 The present invention relates to a gas-liquid separator that separates liquid such as condensed water or condensed water when steam, compressed air, various gases, or the like flows down in a gas pipe.
従来の気液分離器は、気体と液体の混合流体を、フィルターでろ過して両者を分離したり、旋回流を与えて遠心力により分離したり、あるいは、衝突部材に混合流体を衝突させて分離するものである。 Conventional gas-liquid separators separate a mixed fluid of gas and liquid by filtering them, separate them by centrifugal force by applying a swirling flow, or collide the mixed fluid with a collision member. To separate.
上記従来の気液分離器は、気液分離器自身の分離効率の変化を確認することができない問題点があった。気液分離器は、例えば、各種の蒸気使用装置、具体的には蒸気加熱装置とか蒸気タービン等の入口側に取り付けられて、蒸気使用装置へ供給される蒸気から復水などの液体を分離することによって、蒸気使用装置へ復水の分離された蒸気だけを供給するものである。従って、気液分離器の分離効率が変化して、その分離効率が低下すると、蒸気使用装置へ供給される蒸気中に復水を混入した状態となってしまい、蒸気使用装置の加熱効率、あるいは、タービン効率の低下を来たしてしまうのである。 The conventional gas-liquid separator has a problem in that it cannot confirm the change in the separation efficiency of the gas-liquid separator itself. For example, the gas-liquid separator is attached to the inlet side of various steam using devices, specifically, a steam heating device or a steam turbine, and separates liquid such as condensate from the steam supplied to the steam using device. Thus, only the separated steam is supplied to the steam using device. Therefore, when the separation efficiency of the gas-liquid separator is changed and the separation efficiency is lowered, the condensate is mixed in the steam supplied to the steam using device, and the heating efficiency of the steam using device, or The turbine efficiency will be reduced.
本発明が解決しようとする課題は、分離効率の変化を確認することのできる気液分離器を提供することである。 The problem to be solved by the present invention is to provide a gas-liquid separator capable of confirming a change in separation efficiency.
本発明は、蒸気や圧縮空気や各種ガス等が流下する気体管路に取り付けて、混入している復水や凝縮水等の液体を分離するものにおいて、蒸気使用装置の入口側に気液分離器ケーシングを配置し、当該気液分離器ケーシングに、気液分離器で分離された液体量を検出する分離液体量検出手段を取り付けると共に、蒸気使用装置に、蒸気使用装置の加熱効率やタービン効率等の効率を検出する蒸気使用装置効率検出手段を取り付けて、当該蒸気使用装置効率検出手段と分離液体量検出手段との検出値に基づいて、気液分離器の分離効率の変化を確認するものである。 The present invention is attached to a gas pipeline through which steam, compressed air, various gases, etc. flow down, and separates mixed liquid such as condensate and condensed water. A separator casing is arranged, and a separation liquid amount detection means for detecting the amount of liquid separated by the gas-liquid separator is attached to the gas-liquid separator casing, and the steam use device is heated to the heating efficiency and turbine efficiency of the steam use device. A steam using device efficiency detecting means for detecting the efficiency of the gas etc. is installed, and the change in the separation efficiency of the gas-liquid separator is confirmed based on the detection values of the steam using device efficiency detecting means and the separated liquid amount detecting means. It is.
本発明によれば、蒸気使用装置効率検出手段と分離液体量検出手段との検出値に基づいて、気液分離器の分離効率の変化を確認することができる。例えば、気液分離器の分離効率が低下して、分離液体量検出手段での検出値が減少すると共に、蒸気使用装置へ供給される蒸気中に復水を混入した状態となって、蒸気使用装置効率検出手段での検出値が減少したことを検出して、気液分離器の分離効率の低下を確認することができる。 According to the present invention, it is possible to confirm the change in the separation efficiency of the gas-liquid separator based on the detection values of the steam using device efficiency detection means and the separated liquid amount detection means. For example, the separation efficiency of the gas-liquid separator decreases, the detection value in the separation liquid amount detection means decreases, and condensate is mixed in the steam supplied to the steam using device, so that the steam usage By detecting that the detection value of the apparatus efficiency detection means has decreased, it is possible to confirm a decrease in the separation efficiency of the gas-liquid separator.
以下、本発明の実施の形態について、図1を参照して説明する。蒸気使用装置１の入口側に気液分離器２を配置する。気液分離器２の入口側に蒸気供給管３を接続し、気液分離器２の出口側の管路４を介して蒸気使用装置１と接続する。 Hereinafter, an embodiment of the present invention will be described with reference to FIG. A gas-liquid separator 2 is disposed on the inlet side of the steam using device 1. A steam supply pipe 3 is connected to the inlet side of the gas-liquid separator 2, and is connected to the steam using device 1 via a pipe line 4 on the outlet side of the gas-liquid separator 2.
蒸気使用装置１の上部に蒸気使用装置効率検出手段５を取り付ける。蒸気使用装置効率検出手段５は、蒸気使用装置１の加熱効率、あるいは、タービン効率などの効率を検出することができるものであれば良い。例えば、蒸気使用装置１が蒸気加熱装置である場合は、蒸気加熱装置１へ供給される蒸気の総熱量と、蒸気加熱装置１で加熱された被加熱物の総量との比で蒸気使用装置１の加熱効率を検出することができる。なお、蒸気加熱装置１の下部には管路６を介在して蒸気トラップ７を取り付ける。蒸気トラップ７は、蒸気使用装置１内で蒸気の凝縮した復水だけを系外へ排除することができるものである。 A steam use device efficiency detecting means 5 is attached to the upper part of the steam use device 1. The steam using device efficiency detecting means 5 may be any device that can detect the heating efficiency of the steam using device 1 or the efficiency such as the turbine efficiency. For example, when the steam using device 1 is a steam heating device, the steam using device 1 is based on the ratio of the total amount of steam supplied to the steam heating device 1 and the total amount of the object to be heated heated by the steam heating device 1. The heating efficiency can be detected. A steam trap 7 is attached to the lower part of the steam heating device 1 with a pipe 6 interposed. The steam trap 7 can exclude only condensate condensed with steam in the steam using apparatus 1 from the system.
気液分離器２の下部に管路８を介在して蒸気トラップ９を接続し、この蒸気トラップ９の外表面に分離液体量検出手段１０を取り付ける。分離液体量検出手段１０は、蒸気トラップ９から系外へ復水が排出される際に、蒸気トラップ９の内部で復水の流れに伴って発生する超音波を検出することによって、気液分離器２で分離された液体量を検出することができるものである。 A vapor trap 9 is connected to the lower part of the gas-liquid separator 2 via a pipe 8, and a separation liquid amount detection means 10 is attached to the outer surface of the vapor trap 9. The separated liquid amount detecting means 10 detects the ultrasonic wave generated along with the flow of the condensate inside the steam trap 9 when the condensate is discharged from the steam trap 9 to the outside of the system, thereby separating the gas and liquid. The amount of liquid separated by the vessel 2 can be detected.
蒸気供給管３から気液分離器２を通って蒸気使用装置１へ供給される蒸気は、気液分離器２を流下する間に、混入していた復水が蒸気から気液分離され、蒸気使用装置１へ供給される。一方、気液分離器２で蒸気から分離された復水は、蒸気トラップ９から系外へ排出される間に分離液体量検出手段１０でその流量が検出される。 The steam supplied from the steam supply pipe 3 to the steam using device 1 through the gas-liquid separator 2 is separated from the steam by gas-liquid separation while the gas-liquid separator 2 flows down, and the steam It is supplied to the use device 1. On the other hand, the condensate separated from the vapor by the gas-liquid separator 2 is detected by the separated liquid amount detection means 10 while being discharged out of the system from the vapor trap 9.
蒸気使用装置１へ供給される蒸気によって、蒸気使用装置１で図示しない被加熱物が加熱され、あるいは、蒸気タービンが回転駆動され、蒸気が消費される。この消費される蒸気を基に、蒸気使用装置効率検出手段５で蒸気使用装置１の効率が検出される。例えば、気液分離器２の分離効率が低下して、分離液体量検出手段１０での検出値が減少すると共に、蒸気使用装置１へ供給される蒸気中に復水を混入した状態となって、蒸気使用装置効率検出手段５での検出値が減少したことを検出して、気液分離器２の分離効率の低下を確認することができる。 The object to be heated (not shown) is heated by the steam supplied to the steam using apparatus 1 or the steam turbine is rotationally driven to consume the steam. Based on the consumed steam, the efficiency of the steam using device 1 is detected by the steam using device efficiency detecting means 5. For example, the separation efficiency of the gas-liquid separator 2 decreases, the detection value in the separated liquid amount detection means 10 decreases, and condensate is mixed in the steam supplied to the steam using device 1. By detecting that the detection value in the steam using device efficiency detecting means 5 has decreased, it is possible to confirm a decrease in the separation efficiency of the gas-liquid separator 2.
本発明は、気体管路内を蒸気や圧縮空気や各種ガス等が流下する場合に、混入している復水や凝縮水等の液体を分離する気液分離器として利用することができる。 INDUSTRIAL APPLICABILITY The present invention can be used as a gas-liquid separator that separates liquid such as condensed water and condensed water when steam, compressed air, various gases, or the like flows down in a gas pipe.
