Title:
DRAW-IN AND CAST DEVICE FOR NUCLEAR POWER CIRCULATING WATER PREFILTRATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/116525
Kind Code:
A1
Abstract:
The present invention relates to a draw-in and cast device for a nuclear power circulating water prefiltration system, comprising cast cables connected onto net bags, net draw-in cables connected onto the net bags, tensioning cables connected onto the net bags, a draw-in and cast platform, first draw-in and cast units arranged on the draw-in and cast platform, second draw-in and cast units arranged on the draw-in and cast platform, and third draw-in and cast units arranged on the draw-in and cast platform. The first draw-in and cast units are connected to the net draw-in cables so as to drive the net draw-in cables to be lengthened or shortened to implement net cast or net draw-in; the second draw-in and cast units are connected to the cast cables so as to drive the cast cables to be lengthened or shortened to implement net draw-in or net cast; the third draw-in and cast units are connected to the tensioning cables so as to drive the tensioning cables to be lengthened or shortened to assist net cast by the cast cables. The draw-in and cast device for a nuclear power circulating water prefiltration system achieves full-section interception for the filtration system, so that the filtration system is effectively protected, and the efficiency of replacing the filtration system can be improved.
