置する。For example, in the case of a pre-coat type filtration device used in the condensate water supply system of thermal power plants and nuclear power plants, the condensate filtration process involves the condensate passing through a filter medium layer formed on the surface of the filter cloth in the filter 1. This is achieved by If the condensate treatment capacity is large and continuous filtration operation is to be performed, it is normal to install multiple partial volume filters, and consideration should be given to bypass operation of the filtration equipment. Install a bypass pipeline.

復水出口管19へ導かれ、下流系統へ送られる。12 is a condensate inlet pipe, which serves as a zero population of condensate transferred from the higher pressure side upstream system.To the 6-pass filter 11, there is a pipe 13 branching from the condensate inlet pipe 1'2, and an inlet valve. 14, a flow meter 40, etc., a flow control valve 50, and a filter inlet pipe 15, and are led to the filter 11. Condensate d treated by the filter 11 passes through the filter outlet pipe 16, the outlet valve 17 and the pipe 18, is guided to the condensate outlet pipe 19, and is sent to the downstream system.

に移行する場合は、逆の手jIIによって達成される。One method of operation is to supply the entire flow rate □ required by the downstream system of this filtration device via the bypass pipe without passing it through the filter. The filters are sequentially introduced one by one, and after the required number of filtration towers are operated, the bypass valve 21 is closed. Further, when the filtration device is disconnected from the system and transferred to full bypass operation, this is achieved by the reverse procedure jII.

操作は、手動、若しくは、遠隔手動で行なわれる。Conventionally, the above operations have been performed manually or remotely. The condensate inlet pipe 12 is led to the condensate outlet pipe 19 through a branching pipe 20, a bypass valve 21 and a pipe 22, and at this time, 1, 2. ...The artificial valves and outlet valves of all the n-series filters are all closed. From this full bypass operation state, filter version 1
When starting water flow, the inlet valve 14 and the outlet valve 17 are opened, but in Japan, motorized valves are generally used, and this opening operation is performed manually or remotely.

させる。After the water flow to the first series is achieved, the bypass valve 21 of the generally used electric rock drive type is adjusted to open manually or remotely to reduce the flow rate of the bypass water flow.
以上の操作を繰り返すことによって、バイパス運転から
ろ過装置通水運転へ移行させる。By repeating the above operations, the bypass operation is shifted to the filtration device water flow operation.

が長くなるにつれて上昇する傾向にあり、規定差圧ΔP
maxでろ過器の運転を停止し、目詰りしたろ材の除去
及び新ろ材のプリコートのために再生操作を行なう。The operation of the filter is obtained through the filter inlet side pressure obtained through the differential pressure gauge detection pipe 26 connected to the filter inlet pipe 15 and the differential pressure gauge detection pipe 27 connected to the filter outlet pipe 16. The difference between the pressure on the outlet side of the filter and the pressure on the outlet side of the filter is detected by a differential pressure gauge 28, and the differential pressure is used for monitoring.
When operated at L amount, as shown in Fig. 2, it tends to increase as the processing time becomes longer, and the specified differential pressure ΔP
The operation of the filter is stopped at max, and a regeneration operation is performed to remove the clogged filter medium and pre-coat a new filter medium.

、全てのろ過器差圧が規定差圧Δp maxに接近する
ことになる。Here, the flow rate of condensate distributed to each series from the condensate inlet pipe 12 is such that if the piping and valve configurations around the filter are approximately equal, the flow rate of the filtration series with a small differential pressure will increase, and conversely As the flow rate in the series with a large differential pressure decreases, the differential pressure in each series is distributed to be constant, so as shown in Figure 3, the flow rate varies, and if this operation is continued, all The filter differential pressure will approach the specified differential pressure Δp max.
また、この流量アンバランスは、ろ過器の性能を左右す
るろ過速度が変動することにもなる。Moreover, this flow rate imbalance also causes fluctuations in the filtration rate, which affects the performance of the filter.
ここで、ろ過速度とは、ろ材層を通過する原液の速度で
あり、下式により定義される。Here, the filtration speed is the speed of the stock solution passing through the filter medium layer, and is defined by the following formula.

ろ過器を停止する。In a filtration device operated by such an equal flow rate side tilt device, the filter is usually equipped with a spare, so when the filter reaches the specified differential pressure and regeneration operation is required, After putting the spare filter into operation, stop the filter that requires regeneration.

は、再生操作を行なった後、予備として待機させる。In other words, in a filtration apparatus equipped with n filters, normally (n-1) filters are operated and -1 filters are on standby as a spare. If one of the tn-1 filters in operation requires regeneration, the artificial valve and outlet valve of the standby series are opened manually or remotely, and the n-unit operation is temporarily established. After that, the large mouth valve and outlet valve of the filter that needs to be regenerated are closed, and (n-11 units are operated.) After the regeneration operation is performed, the filter is kept on standby as a standby.
近年、火力・原子カプラントでは、合理化によりろ過器
の予備を削除する傾向にあり、下記の考慮、すべき問題
が生じてきている。In recent years, thermal power and nuclear power plants have tended to eliminate spare filters due to rationalization, and the following issues have arisen that should be considered.

なってしまう。In addition, conventionally, when a filtration device is connected to or disconnected from the system, the bypass valve is operated manually or remotely, which makes the operation extremely complicated and
When a pump is installed on the upstream side, such as in the condensate system of an atomic coupler, there are factors such as upstream pump trips due to operational errors. Furthermore, in the case of a side stream type pump, the side stream pump may operate at an excessive flow rate.
