Description
Technical Field
The invention relates to a steam-water separation reheater in a nuclear power conventional island, in particular to a container support system.
Background
A Moisture Separator Reheater, namely, a Moisture Separator and regenerator, is abbreviated as MSR. MSRs and turbo-generators are the main components in conventional islands of nuclear power plants. The MSR may remove a substantial portion of the water from the steam exiting the high pressure cylinder of the steam turbine generator and may also increase the temperature of the steam before the steam enters the low pressure cylinder of the steam turbine generator.
MSRs typically include a housing. The abutment system of an MSR typically comprises several abutments. Each support needs to hold the housing to provide support and fixation for the MSR. A plurality of pipelines are usually arranged between the MSR and the steam turbine generator, and the pipelines can be used for transmitting heat-conducting media between the MSR and the steam turbine generator. Because the MSR generates temperature change during operation, the temperature change can cause the shell of the MSR to generate thermal expansion. Thermal expansion can cause dimensional changes in the housing and can also cause thrust between the tube and the housing, which can lead to vibration and displacement of the housing. The mount system is usually required to be movable in order to accommodate vibration and displacement of the housing.
Each support is required to accommodate not only the weight of the MSR, but also the displacement of the housing due to thermal expansion, and the thrust between the housing and the pipe.
In the prior art, in order to accommodate the displacement of the housing caused by thermal expansion, the mount system generally comprises a fixed mount and a sliding mount. The sliding support is provided with a waist-shaped hole, and the connecting piece can pass through the waist-shaped hole, so that the sliding support can slide along the length direction of the waist-shaped hole, and the thermal expansion of the shell can be adapted.
In the prior art, in order to adapt to the relative displacement between the shell and the pipeline, an expansion joint is further arranged between the shell and the pipeline, and the expansion joint can be stretched and deformed, so that the thermal expansion difference between the pipeline and the shell is eliminated, and the relative displacement between the shell and the pipeline is adapted.
The technical drawbacks of the prior art abutment systems are: the diameter of the pipeline is large, and a specially-made expansion joint needs to be arranged, so that the selection and the manufacture of the expansion joint are difficult, and the reduction of the manufacturing cost is not facilitated; the matching relationship between the sliding support and the mounting base in the sliding process is surface contact, so that the flatness matching requirement between the sliding support and the mounting base is higher, and the manufacturing and assembling difficulty of the support system is higher; the sliding fit between the sliding support and the mounting base is easily interfered by external factors to cause unsmooth sliding, so that the thermal expansion of the shell cannot be fully released, and the shell and the support have the risk of deformation and damage.
