DEVICE FOR DECONTAMINATING HEAT-TRANSFER SURFACE OF STEAM GENERATOR |
摘要 |
thermal engineering. SUBSTANCE: packing device 4 is installed in bottom part of headers 1 and 2 of steam generator 3 to isolate the headers from primary circuit. Platform 5 mounting submersible or semisubmersible pump 6 is installed on flange of header 1. Platform 5 is set in rotary motion about header by means of electric motor 7 via reduction unit 8. Dispensing device 10 made in the form of nozzle and connected to pump 6 is used for feeding decontaminating solution over tubes of heat-transfer bank 9. Header 2 is covered on top with lid 11 that has decontaminating solution supply nozzle. EFFECT: reduced mass and size, facilitated mounting and dismounting, reduced power requirement for decontamination process. 2 dwg |
