Description

A kind of nuclear power plant's sump filter

Technical field:

The utility model relates to sump filter technical field more particularly to a kind of nuclear power plant's sump filters.

Background technique:

The effect of containment sump is to collect the heap in loss of-coolant accident (LOCA) in the case where recycling water storage tank water shortage Core cooling water, presurized water reactor coolant loss (LOCA) loss of-coolant accident (LOCA) occurs for nuclear power station and high energy pipeline breaking accident (HELB) generates Shock wave and injection stream insulating layer, painting layer and the cement layer of badly damaged cut near zone are formed it is many broken Piece.Fragment will be transferred to the bottom of containment under steam, flow action.Therefore setting sump filter is for filtering Cooling water blocks melt pit to avoid clast, influences circulation waterway.Reactor core lose recirculated water again cool down after, core temperature will be made It is steeply risen with pressure and causes reactor core to melt and cause to pacify to destroy the shielding guaranteeing role of containment with containment superpressure Radioactive substance is discharged to space in full shell.

As the important equipment that can ensure nuclear island safety when major accident occurs for primary Ioops, sump filter is in safety Play a significant role in shell, existing filter has that filtering is not thorough, fragment is easy blocking.

The information disclosed in the background technology section is intended only to increase the understanding to the general background of the utility model, and It is not construed as recognizing or implying in any form that information composition is already known to those of ordinary skill in the art existing Technology.

Utility model content:

The purpose of this utility model is to provide a kind of nuclear power plant's sump filters, thus overcome it is above-mentioned in the prior art Defect.

To achieve the above object, the utility model provides a kind of nuclear power plant's sump filter, the filter both ends It is provided with end plate, the end plate at the both ends is set between the filter plate and filter plate in parallel using one group or more filter plate connection It sets；It is provided with two groups of filtering module between the filter plate, is connected between two groups of filtering modules using expansion tube, it is described Every group of filtering module is made of one group or more of filter element, and the single filter element is made of two filter cores, two filter cores It is separately positioned between two pieces of filter plates, forms busway between described two filter cores, uniformly set on the outside of the filter plate It is equipped with reinforcement block.

Mounting ring is provided on the end plate.

Reinforcement block is provided with outside the end plate.

Compared with prior art, the utility model has the following beneficial effects:

The sump filter of the utility model is provided with filter plate outside filter core, can carry out coarse fragments primary filtration, so Afterwards using filter element filtering, it is possible to prevente effectively from the problem of clogged with fragments filter；The utility model uses two groups of filtering modules Setting can be improved filter effect, and between two groups of filtering modules using expansion tube connect, it is easy to disassemble.

Detailed description of the invention:

Fig. 1 is a kind of main view of nuclear power plant's sump filter of the utility model；

Fig. 2 is a kind of cross-sectional view of nuclear power plant's sump filter of the utility model；

Appended drawing reference are as follows: 1- end plate, 11- mounting ring, 2- filter plate, 21- reinforcement block, 3- filtering module, 31- filtering are single Member, 32- filter core, the busway 33-, 34- manifold port, 4- expansion tube.

Specific embodiment:

Specific embodiment of the present utility model is described in detail below, it is to be understood that the protection of the utility model Range is not limited by the specific implementation.

Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " includes " or its change Changing such as "comprising" or " including " etc. will be understood to comprise stated element or component, and not exclude other members Part or other component parts.

As shown in Figs. 1-2, a kind of nuclear power plant's sump filter, the filter both ends are provided with end plate 1, the both ends End plate 1 connected using one group or more filter plate 2, be arranged in parallel between the filter plate 2 and filter plate 2；The filter plate 2 it Between be provided with two groups of filtering module 3, connected between two groups of filtering modules 3 using expansion tube 4, every group of filter module Block 3 is made of one group or more of filter element 31, and the single filter element 31 is made of two filter cores 32, and two filter cores 32 divide Busway 33 She Zhi not be formed between described two filter cores 32,2 outside of filter plate is uniformly between two pieces of filter plates 2 Be provided with reinforcement block 21.

Mounting ring 11 is provided on the end plate 1.

Reinforcement block 21 is provided with outside the end plate 1.

When implementation, Core cooling water is filtered after 2 prefiltration of filter plate intercepts partial piece using filter core 32, water Stream enters busway 33, and the manifold port 34 formed at through two pieces of 2 bottom openings of filter plate flows out；The ground of the utility model Hole filter is provided with filter plate 2 outside filter core 32, can carry out coarse fragments primary filtration, then filters using filter core 32, It is possible to prevente effectively from the problem of clogged with fragments filter；The utility model can be improved using the setting of two groups of filtering modules 3 Effect is filtered, and is connected between two groups of filtering modules using expansion tube 4, it is easy to disassemble；The utility model is in filter plate 2, end plate 1 It is provided with reinforcement block 21 outside, hydraulic pressure excessive the problem of causing filter damage can be effectively prevented；The filtering of the utility model Device structure is simple, and filter area is larger.
