Description

A bag filter filtering system of lancing water treatment facilities for lancing equipment for removing sediment of steam ganerator in nuclear power plant}

The present invention relates to a bag filter filtration system of a lancing water treatment facility for a lancing device for removing deposits from a nuclear power plant steam generator, and more particularly, a bag for removing sludge contained in sprayed water collected in a sludge tank among the lancing devices. When the sludge accumulates in the bag filter among the (bag) filters and cartridge filters and needs replacement, the sludge removal operation in the sprayed water is stably maintained and moisture is evaporated through the drying process of the bag filter to be replaced. By reducing the weight of the bag filter, the bag filter to be replaced can be handled more safely, and there is no leakage from the bag filter to be replaced with a reduced moisture content, so contamination of the floor of the lancing process can be reliably prevented. It relates to a bag filter filtration system of a lancing water treatment facility for a lancing device for removing deposits from a nuclear power plant steam generator having a structure.

In general, the steam generator of a nuclear power plant is a place where the primary and secondary systems that receive heat energy generated from the nuclear reactor meet, and is a very important structure in which heat exchange occurs by bordering the heat transfer pipe of the steam generator. Turns the turbine and converts kinetic energy into electrical energy to generate power. However, as the operation history of the nuclear power plant increases, the secondary system pipes wear out, and the metal components released from the pipes are deposited as sludge in the steam generator or fall from the structure due to maintenance during the planned prevention period of the nuclear power plant. The resulting components flow into the steam generator and exist as foreign substances.

Such steam generator sludge is divided into soft sludge and hard sludge with relatively hard sludge strength, and in the case of soft sludge, it is usually deposited in the upper layer of the steam generator, and in the case of hard sludge The sludge deposited on the tube-sheet at the bottom of the steam generator is deposited in the form of hard sludge by the hot heat of the heat transfer pipe.

The sludge deposited in this way lowers the heat transfer capacity of the steam generator customs, resulting in lower heat output efficiency and ultimately affects the power plant's output decline.In the case of overseas nuclear power plants, it has been reported as a case of shutdown of the power plant due to the power decrease. In addition, there is a huge economic loss due to the early replacement of the steam generator due to local corrosion of the steam generator.

Therefore, a steam generator lancing equipment that can easily remove sludge and foreign matter deposited on the steam generator tube sheet by passing between the heat transfer pipes with narrow spacing of the steam generator heat plate has been developed, and is currently used in the steam generator of a nuclear power plant. , These specific details are published in Korean Patent Registration No. 10-0820236 (2008. 04, 01. registration).

1 is a system diagram illustrating a water supply and recovery system (shown including a steam exhaust line (SDL), which is one of the good elements of the present invention) for such a conventional steam generator lancing equipment.

As can be seen from FIG. 1, the existing steam generator lancing equipment sprays high-pressure water to remove foreign substances other than the sludge deposited on the steam generator tube sheet, thereby supplying water essentially and containing sludge and foreign substances. It includes a lancing water treatment facility that recovers the sprayed water, removes sludge and foreign matter, and supplies it to the lancing equipment again.

In this lancing water treatment facility, sludge and foreign matter removed from the steam generator tube sheet by high pressure sprayed water by the lancing equipment are collected at the bottom of the steam generator together with the sprayed water, and these sludge and foreign matter Together with the sludge suction pump (Sludge Suction Pump) is collected through the recovery line to the sludge tank (ST), and the sludge collected in the sludge tank (ST) and the sprayed water containing foreign substances are transferred by the transfer pump to the bag filter. After passing through the Bag Filters System (10) and Cartridge Filters Tank (CFT), the contained sludge and foreign substances are removed, and then stored in the washing water storage tank (WAT), and annular flush pump (Annulus Flush). Pump) is transported to a barrel spray pump and a high pressure pump, respectively, and supplied to a steam generator lancing device.

It is noted that the present invention relates to a bag filter replacement system among lancing water treatment facilities that supply water to the existing steam generator lancing equipment and recover sprayed water, and hereinafter, it is understood that only the bag filter replacement system is described in the present specification. Please do.
