Embodiment Construction

[0023] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0024] combine Figure 1 to Figure 3 As shown, the present invention provides a containment recirculation filter connection module 2, which is used to be arranged between two adjacent filter modules and to connect the two filter modules. The containment recirculation filter connection module 2 includes a main body 20 , at least two elastic pieces 21 and at least two elastic pieces 22 .

[0025] The main body 20 is a frame structure with a cavity in the middle and includes opposite and parallel upper walls 201 and lower walls 202 and opposite first side walls 203 and second side walls 204. Both ends of the upper wall 201 are respectively fixed on the second One end on the height direction of the side wall 203 and one end on the height direction of the second side wall 204, and the two ends of the lower wall 202 are respectively fixed on the other e...

Abstract

The invention discloses a connection module of a containment recirculation filter, which includes a main body, at least two elastic pieces and at least two elastic pieces. The main body includes opposite upper and lower walls and opposite first and second side walls. The two ends of the upper wall are respectively fixed on one end of the first side wall and one end of the second side wall. The other end of the first side wall and the other end of the second side, the length of the first side wall is less than the length of the second side wall, and both the upper wall and the lower wall are roughly trapezoidal. The openings at both ends of the main body are respectively provided with connecting flanges that are turned outwards relative to the upper wall, the lower wall, the first side wall and the second side wall. The outer sides of the two connecting flanges are provided with shrapnel and elastic pieces, the inner edge of the shrapnel is fixed to the connecting flange, the outer edge of the shrapnel is spaced from the connecting flange, and the elastic piece is clamped between the shrapnel and the connecting flange. The connecting module is beneficial to the installation and angle adjustment of the filter module, and also has the functions of the pipeline module and the connecting piece, and at the same time, there is no need to set a sealing structure.

Description

technical field [0001] The invention relates to the technical field of safety systems of pressurized water reactor nuclear power plants, in particular to a connection module for a containment recirculation filter. Background technique [0002] The pit located at the bottom of the containment vessel of the pressurized water reactor nuclear power plant is used to collect the coolant from the primary circuit in case of major leakage. After a basic accident in a pressurized water reactor nuclear power plant, such as a loss of coolant accident (LOCA) or a main steam line rupture accident (MSLB), the coolant enters the containment pit through the breach, and the coolant will pass through the containment pit in the pit to re- The circulating filter is filtered, and then enters the safety injection system (RIS) and the containment spray system (EAS) through the pump device, and is used for reactor cooling to avoid serious damage to the core and overpressure of the containment.
