To see figures.1.and.2 below and specify the plurality of advantages of the utility model:
1, the loop hot-pipe condenser is made up of evaporator section 103, condensation segment 102 and relevant end socket pipeline 104 etc.; Its heat extraction principle be under the accident in the containment 100 vapoury mixed gas 106 condense in loop hot-pipe condenser evaporator section 103 outsides; Intraductal working medium under low pressure seethes with excitement and takes away heat through phase transformation; Forming two phase Natural Circulation in the loop flows; The steam that the evaporator section boiling produces condenses in the condensation segment pipe of top, loop, and the reserve tank 101 (PCCWST) at containment top is the ultimate heat sink of heat pipe condenser.Its concept structure form is as shown in Figure 1.What the loop hot-pipe condenser system that the utility model relates to adopted is non-active theories such as Natural Circulation, action of gravity, chimney effect; Abandoned traditional active equipment (like pump, blower fan) that adopts in fields such as chemical industry; When satisfying the heat extraction requirement, simplified system.The utility model and with current non-passive safety shell heat extraction condenser maybe than what isolated further that accident transfers that penetrating property gas leaks.Present non-passive safety shell heat extraction condenser or the radioactivity mixed gas introduced the containment condensed exterior or the water that containment is outer is introduced condensation mixed gas in the containment has the isolation that radioactive mixed gas and shell water outward has only one deck heat exchange wall in this case; And the leakage of the utility model radgas need be through two-layer, and promptly radgas needs leak in the circuit system of loop hot-pipe condenser through a side heat exchange wall earlier, and then the heat exchanger tube that sees through condenser top is released outside the shell in the pond.Therefore the utility model has more the anti-leak advantage by contrast.
2, thereby the utility model is provided with anti-chimney effect fair water fin (air deflector) 105 for the heat exchange effect of the souring enhancing heat exchanger tube of 106 pairs of loop hot-pipe condensers of increase containment 100 internal gas flows evaporator section out-tubular condensing liquid film around evaporator section 103.The coefficient of heat transfer because air-flow can quicken coming off of liquid film in the same way with the droplets fall of condensing, thereby is improved in the zone that should be arranged in the landing of containment internal gas flow of loop hot-pipe condenser evaporator section.Fair water fin can quicken flowing of mixed gas through anti-chimney effect, and its souring helps coming off of liquid film.Fair water fin is wide at the top and narrow at the bottom, and steering current washes away heat exchanger tube with the evaporator section size design, and this does not have in the separate type heat pipe exchanger that fields such as chemical industry are used always.In addition, fair water fin also has the effect of protection evaporator section heat exchanger tube.
3, the heat exchanger tube of the evaporator section 103 of loop hot-pipe condenser is in tilted layout.In the ordinary course of things, heat exchanger tube is vertical layout.The containment air motion is different with other field; The effect of the interior mixed gas flow direction of shell process fair water fin is top-down one and flows; Lateral arrangement or be in tilted layout can with the sufficient heat exchange of air-flow; But the heat exchange efficiency that the heat exchanger tube lateral arrangement is not in tilted layout is high, and pipeline is in tilted layout and also makes things convenient for out-tubular condensing liquid to lean on action of gravity to stay smoothly, and the angle of inclination needs systematic comprehensive fair water fin effect research back decision.
4, the version of loop hot-pipe condenser condenses section 102, condensation segment collector pipe 1021,1022.Reserve tank 101 structurally associateds at the top of condensation segment heat exchanger tube 1023 arrangement forms and containment 100; For guaranteeing that to greatest extent heat exchanger tube is immersed in the water; Avoid causing too early being exposed in the air of heat exchanger tube along with the accident process water level reduces, the condensation segment heat exchanger tube should be pressed close to water tank bottom and keep certain distance to be in tilted layout.Descending most discharge pipe and water tank bottom should keep certain distance is in order to prevent that the row's heat exchanger tube that descends most that incrusted deposit causes lost efficacy.The condensation segment tube bank sees it should is that arc is arranged from the square section, connect the also curved layout of collector pipe of condensation segment tube bank.As shown in Figure 2.This is for utilizing the optimization of the partial structurtes that containment upper tank space carries out to greatest extent.
5, bushing type recirculatory pipe (pipeline) 104.Containment is to contain last one barrier that radiomaterial leaks, and the penetration piece number is significant to being kept perfectly property under its accident.The pipeline 104 that connects evaporator section, condensation segment collector pipe need run through containment, and for reducing the penetration piece number, the utility model has been invented a kind of sleeve pipe recirculatory pipe, avoids penetration piece too much to bring influence with excessive the dispersion to containment with this.Sleeve pipe recirculatory pipe penetration piece is as shown in Figure 1.The steam that produces in the heat pipe condenser loop transfers out containment through the first path 104a of sleeve pipe, and the working medium that the condensation of heat pipe condenser condensation segment is got off is back to evaporator section through the alternate path 104b of sleeve pipe.As shown in Figure 1, in the utility model, sleeve pipe 104 is the unique pipelines that connect evaporator section 103 and condensation segment 102, also is the penetration piece that runs through containment 100.
Although illustrated and described the embodiment of the utility model, for those of ordinary skill in the art, be appreciated that under the situation of principle that does not break away from the utility model and spirit and can change these embodiment.The scope of application of the utility model is limited accompanying claims and equivalent thereof.In addition, any element numbers of claim should not be construed as the scope of restriction the utility model.
