CONNECTING MODULE FOR CONTAINMENT RECYCLING FILTER
FIELD OF THE INVENTION [0001] The invention relates to pressurized water reactor nuclear power plant safety system, and more particular to a connecting module for a containment recycling filter.
BACKGROUND OF THE INVENTION [0002] A containment sump configured at a bottom of containment in pressurized water reactor nuclear power plants is used for collect coolant from a primary circuit once a major leakage accident happens. After basis accidents such as LOCA (Loss Of Coolant Accident) or MSLB (Main Steam Line Break Accident) happens, the coolant will enter to the containment sump through the break, which will pass through a containment recycling filter in the sump, and then enter to a RIS (safety injection system) and EAS (containment spray system) for reactor cooling, so as to prevent severe damage of the reactor core and overpressure of the containment.
[0003] The coolant in the sump is mixed up with a large quantity of fragments of thermal insulation materials or other materials, which is required to filter by means of recycling filters, so as to ensure the safety of the RIS and the EAS. By this token, the containment recycling filter is critical equipment in water reactor nuclear power plant safety system.
[0004] A conventional containment recycling filter mainly includes multiple filter modules al which are arranged along the sump corridor b, as shown in Fig. 1. Apparently, an angle is formed between two adjacent filter modules al. For connecting the two adjacent filler modules al, the collector groove all of the filter module al is required to be formed in a trapezoidal structure with one straight side and an inclined side as illustrated in Fig. 2. Such filter module al with fixed trapezoidal structure can only he arranged in a fixed radius, which is applicable to only one type of containment sump with the certain standard and specification. Regarding to different sumps with different standards and specifications, multiple filter modules al with different trapezoidal structures are required, which increases manufacturing cost and brings inconvenient assembly.
[0005] Additionally, since the positions of the four recycling pump entrances (including two RIS entrances and two EAS entrances) in the sump are fixed, thus the quantity of the filter modules al configured between the two closer entrances is relative small, which may reduce the filtering area and filtering efficiency, and furthermore the filtered coolant quantity at the two entrances is smaller than the rest two. For eliminating the differences of filtering efficiency and filtered coolant quantity, a pipeline module a2 is required to set between the two entrances. This pipeline module a2 is connected with the filter modules al, further, a sealing structure is needed to be set between the pipeline module a2 and the filter modules al, and thus the assembly is inconvenient. [0006] Therefore, to solve the above problems, it is necessary to provide a connecting module, which is served as a pipeline module without an additional sealing structure, can adjust disposal angles of filter modules and has simple assembly.
SUMMARY OF THE INVENTION [0007] One objective of the invention is to provide a connecting module for a containment recycling filter, which is served as a pipeline module without setting an additional sealing structure, can adjust disposal angles of filter modules and has simple assembly.
[0008] To achieve the above-mentioned objective, the present invention provides connecting module for a containment recycling filter includes a main body, at least two elastic sheets and at least two elastomers. The main body comprises an upper wall and a lower wall that are opposite to each other, as well as a first side wall and a second side wall that are opposite to each other, two ends of the upper wall are respectively fixed at one end of the first side wall and one end of the second side wall, two ends of the lower wall are respectively side wall and another of the second side waH the first side wall is shorter than the second side wall, and both the upper wall and the lower wall are approximately trapezoidal; two connecting flange parts are respectively provided at openings at two ends of the main body and extended outwards relative to the upper wall, the lower waif, the first side wall and the second side wall; the elastic sheets and the elastomers are disposed outside the two connecting flange parts, inner edges of the elastic sheets are fixed to the connecting flange parts, a spacing is formed between outer edges of the elastic sheets and the connecting flange parts, and the elastomers are clamped between the elastic sheet and the connecting flange parts.
[0009] In comparison of the prior art, the connecting module for a containment recycling filter of the present invention has the following advantages.
[0010] First, since the lengths of the first and the second side walls of the main body is different, and the upper and the lower walls are trapezoidal, thus the profile of the connecting module is in trapezoidal structure with two different-size ends. During the assembly process of a filter, the connecting module is configured between two adjacent filter modules, in such a way, the trapezoidal structure of the connecting module fits with the angle of the two adjacent filter module to accomplish the connection with the two filter modules, and it’s unnecessary to form the collector groove of the filter modules in trapezoidal shapes, thus the filter modules can be formed in uniform standard and specification, which reduces manufacturing cost and assembly difficulty. With using different connecting modules, multiple filter arrangements can be achieved by means of the same filter modules so as to meet different environment demands. Second, the main body of the connecting module plays the same role as conventional pipeline module, thus pipeline module with complex standards is omitted. Furthermore, after the connection between the connecting module and the filter modules, the elastic sheets and the elastomers are clamped between the connecting module and the filter modules, thus seal between the between the connecting module and the filter modules is achieved by means of elastic restoring forces, without setting additional sealing structures, which is beneficial to assemble.
[0011] Preferably, each connecting flange part is in a closed structure that embraces the opening of the main body, and the elastic sheets and the elastomers are in corresponding closed structure.
[0012] Preferably, cross sections of the elastomers are circular, and the outer edges of the elastic sheets are bent to receive the elastomers.
[0013] Preferably, the elastomers are metal net twines that are formed by rolling a metal net and connected end to end, [0014] Preferably, an upper enhanced rib is configured at the upper wall, and two ends of the upper enhanced rib are respectively fixed at the two connecting flange parts.
[0015] Preferably, a lower enhanced rib is configured at the lower wall, and two ends of the
fixed at the two connecting flange parts.
[0016] Preferably, two side enhanced ribs are configured at the side wall and the second side wall respectively, and two ends of each side enhanced rib are respectively fixed at the two connecting flange parts, [0017] Preferably, a bolt is provided at the side enhanced ribs.

With using different connecting modules 2, multiple filter arrangements can be achieved by means of the same filter modules so as to meet different environment demands. Second, the main body 20 of the connecting module 2 plays the same role as conventional pipeline module, thus pipeline module with complex standards is omitted. Furthermore, after the connection between the connecting module 2 and the filter modules, the elastic sheets 21 and the elastomers 22 are clamped between the connecting module 2 and the filter modules, thus seal between the between the connecting module 2 and the filter modules is achieved by means of elastic restoring forces, without setting additional sealing structures, which is beneficial to assemble.
