Abstract

In order to prevent the fact that in the nuclear power plant after the blowoff of the steam through a blowoff pipe (12) the cooling liquid (f) would be sucked in the blowoff pipe (12) undesirably high, a ventilating opening (18) is provided, said opening connects through a flow route (18, 20, 22, 40) the gas range (6a, 8a) above the cooling liquid (f), in which the blowoff pipe (12) is immersed, with the interior space (19) of the blowoff pipe (12). The flow route (18, 20, 22, 40) is thus open and free from valves or movable parts, and preferably has different flow resistances for the two opposite directions.

Description of invention (· >) Leak Tube-use #Ventilation device with an open flow path does not require maintenance because it does not require movable parts in terms of function. The flow path and the vent can be constructed using a simple depression in the wall tube of the drain tube. It would be better to install a snorkel so that the flow path would stretch in it. In this way, it is easy to guide the steam in the vent pipe to vent through the vent pipe or use the gas flowing in the channel pipe to vent in a favorable shape. The shape of the flow path can make the steam flowing out of the vent pipe Flow resistance, the so-called bleed resistance is greater than the flow resistance of the gas flowing in the bleed tube. The difference in flow resistance depends on the flow direction, so the steam force should be reduced as much as possible in the flow path. This vented steam can also be referred to as a steam-leakage flow. The bleed resistance is best determined by a so-called edge mouth. The effective airflow cross section of the device with the edge opening in the discharge direction is smaller than the effective air flow cross section in the opposite discharge direction. If the gap between the outflow resistance and the inflow resistance is expected to be greater, the best way is to install a flow restrictor, which constitutes a Twist element, so that the outflow steam generates a Twist flow ), The limiter is installed in the flow path. Using the torsion element, pressure-related steam, especially when entering the flow path, will turn into a rotating motion. Therefore, the axial flow velocity is reduced. If compared with the inflow resistance row of pure axial flow without twisting, the inflow resistance of such rotating airflow becomes significantly larger. Guiding the flow path in an advantageous shape can make the steam and cold flow out (please read the precautions on the back before filling this page) The paper wave scale is applicable to the Chinese National Standard (CNS) Α4 size (2 丨 〇 × "7mm) ) A7 ί 4 4 9 7 5 5 Β7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. 5. Description of the invention (4) 1 I The liquid is condensed by direct or indirect contact. Therefore, it can be avoided indoors. 1 1 Necessary high pressure formation 〇1! In addition, the vent pipe can not only read 1 above the water-filled level of the coolant, but also connect the drain pipe below it. Read 1 However, the vent pipe It is advisable to connect the bottom of the filling level to the back-1 1 to 1 drain pipe. Therefore »At least part of the vent pipe is led and noticed. 1 I passes through the cooling fluid 0 so the steam flowing out is already in the The inside of the trachea is condensed by the contact between the wall of the trachea and the cooling liquid. 1 Write 1 r Ventilation α means to point down the cooling fluid. 0 The vent tube is toward the vent as far as possible.

This example represents an extra structure S of the bleed tube so that the protection tube can assume its function in the event that the LI of the bleed tube may rupture. It is advisable to form a depression in the protection tube.

Description of the invention (9) The steam in the container 4 is evacuated through the discharge pipe 12 and is discharged from each discharge port installed on one end Ifi of the discharge pipe 12 The inside of 17 flows into the cooling liquid f and is condensed in the cooling liquid. When the pressure in the reactor pressure vessel 4 drops below a predetermined value, the safety / release valve 14 is closed. During the bleed, each bleed pipe 1 2 is completely filled with steam. After the Anjin / release valve 14 is closed, the steam flows into the cooling fluid f in the bleed pipe 12 through the end-to-end discharge port 17. Since the steam still in the discharge pipe 12 is cooled and condensed, a vacuum is formed in the internal space 13 of the discharge pipe 2 so that the cooling liquid f in the discharge pipe 12 is sucked up to a level 'This level is located above the filling level in the overflow tank 8 or the condensation chamber 6 above 11 °, so' The coolant f can reach the safety / release valve 14 and after the hot steam becomes cold coolant f from now on, so The maggot was subjected to a heavy thermal load. According to the second figure, the discharge pipe 12 is first introduced horizontally from the pressure chamber 9 and passes through the partition wall 10, and then, for example, it can be passed into an overflow tank 8 'directly in front of the inlet of the discharge pipe 12 in the gutter tank 8. It is connected to the safety / release valve 14 in the pull pipe 12. The drag tube 12 inside the overflow tank 8 turns sharply downward 90 degrees and extends vertically downward into the cooling fluid f ', which has reached the filling level quotient η. An end piece 16 is installed on the lower end of the drain pipe, and the end piece is perpendicular to the drain pipe 12 and extends in the horizontal direction. The end piece 16 constitutes a plurality of discharge ports 17, and the steam in the discharge pipe 12 flows out from each discharge port, or the cooling fluid f may flow into the discharge pipe 2 from the discharge port.

Invention Explanation (^), and the upper and horizontal levels of η are provided with an air vent 18. The air vent is connected to the internal space of the vent tube 12 through a vent tube 20 and a nozzle 22 that forms a line port W. In this case, the flow path is composed of the vent 18, the vent tube 20, and the nozzle 22. The vent tube 20 is vertically long downward from the drain pipe 12 toward the lower side of the cooling liquid f. So that the outflowing steam for condensation may impinge on the surface quotient of the cooling fluid f. For example, the vent 18 is arranged in the gas range 8a of the overflow tank 8 and is at the filling level quotient n of the cooling fluid f. The upper part is about 1 meter, and the position is 0.3 meters. * Since the air duct 20 and the air vent 18 can flow in two directions, it can also be called the exhaust pipe and Vent 2nd _shows that the bleed tube is in the normal operating state of the nuclear power generation equipment, in other words, when the safety / release valve 14 is closed. In the normal operating state, the bleed tube 12 is filled with the coolant in the flow table 8 on the filling level π of the f. When the safety / release valve 14 is opened, the steam flows out through the discharge pipe 12 and the flow hips in the discharge pipe 12 are pressed by the flow outlets 17 in the end piece 16 Into the trough 8. The 4th to 8th circles respectively show the filling positions opposite to each other, generally cannot be exceeded after the steam is pulled in the discharge pipe 12 and the safety / release valve 14 is closed. The filling position is printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The third figure represents the enlarged part of the cutting part marked with a circle around the nozzle 22 in the second figure. The air pipe 20 and the nozzle 22 are welded to the outer wall 25 of the vent 啻 12 and to each welding point 24.

Description of the invention (u) The distance between the ventilation tube 20 and the protection tube 30 constitutes a so-called leakage opening 34, and the leakage opening should be closed. In addition, the leaky mouth is also covered by a cover 3 (5. The cover 36 constitutes a two-piece type, in which the first part is fixed to the upper part of the ventilation pipe 20 to form a porous_disc-shaped plate 3 8 The second part is a cover or cover 39, which may also form a special perforated disk shape and is fixed on the protective tube 30. When viewed in the cross-sectional view of the cover 39, it is surrounded by The "L" shape is formed within the range, and the partition 38 is β. The partition is arranged between the cover 39 and the protective tube 3G. In Figure 9, 刖 represents a flow limiter (Flow li Bliter). 40 and can be used as an alternative example type. The limiter is partially arranged inside the drain pipe 12 and extends into the vent pipe 20. If a flow restrictor 40 is provided, the gas and The flow (F), ow resistance between the steam flowing out of the drag pipe 12 can reach a very large difference, and the flow limiter 40 is also connected in the flow path. In this example, the flow path is pseudo The β flow restrictor 40 is composed of a flow restrictor 40, a vent tube 20, and an air vent 18 that is not shown in Fig. 9. Element (Twist eleeent) 42, steam flowing through the turning element is in a rotating or spiral flow and is immediately introduced into the air duct 20. The twisted steam is axially along a longitudinal axis 48 and Flow. The turning element 4Z includes a slightly disc-shaped steam inlet member 44, and an outer end is provided with a steam flowing element 4G, such as a Twisted blade. Yes. If 4G is generated, the steam flow is first drawn into the disc-shaped steam inlet member 44 to flow in the radial direction and rotate in a rotating manner to flow along the axis 48. -1 3- This paper has two difficulties in the application of this paper.

Description of the invention (p) An air current rotating or rotating about the longitudinal axis 48 can be formed in the disc-shaped steam inlet member 44, At the same time, the airflow flowing along the longitudinal axis 48 of the ventilation tube 20. In the direction of the longitudinal axis 48 The turning element 4 2 expands into a form of a Diffuser 50. In addition, the flow limiter 4 (5 in an advantageous manner constitutes a cross-section and narrowing element 5 2, for example, the element is a It is in the form of a Venturi tube and is connected to the rotation element 42 in the flow path. Although the point of the configuration of the restrictor 40 is that the restrictor pair flows out of the drain pipe 12 The steam constitutes a great flow resistance. On the contrary, the gas flowing out of the vent pipe 20 is hardly affected by the flow restrictor 40 in the vent pipe 12. The working principle of the flow limiter 4 G is based on a form of revolving flow (i Twisted flow), and the speed of revolving flow increases sharply due to a narrowing effect of a cross section. Therefore, if the static pressure decreases within the range of the rotation or longitudinal axis 48, the vacuum will be formed according to the difference of flow customs. The effective flow cross-section of the outflow steam is limited based on the reduced cross-sectional area of the high centrifugal force of the vent tube 20 and the distance from the longitudinal axis 48. It is difficult to have steam flowing around the longitudinal axis 48. The reduction of the effective flow cross-section is used, and the reduction of the effective cross-section quotient is made larger by the cross-section narrowing member 52. Therefore, the flow restrictor 40 forms a large flow resistance to the outflow steam. In the opposite flow direction, the gas that is trapped in the bleed tube 12 is compared with purely axial flow, which is hardly affected by the flow limiter 40 using the tft rotating element 42 in the bleed tube 12 Outflow.
