Description
Technical field
What the present invention relates to is a kind of gas discharging apparatus, specifically a kind of gas discharging apparatus that is applicable to the long-term water seal resistance of band of water tank.
Background technology
Third generation nuclear reactor system adopts a large amount of non-active cooling systems to improve the security of nuclear reactor system.Passive containment cooling system is one of them; Its Main Function is under some major accident condition, and the gas temperature in containment and pressure are controlled within limits, keeps the integrality of containment, prevents the release of radiomaterial.
For Passive containment cooling system, usually adopt external cooling water tank and a certain amount of chilled water is housed as low-temperature receiver.When major accident appearred in nuclear reactor system, the chilled water in Passive containment cooling system became steam because of the heat in the absorption safety shell.These steam are discharged into cooling water tank, and further are discharged to external environment by cooling water tank.
In view of the safety and reliability of nuclear reactor system, Passive containment cooling system may be in stand-by state and off working state for a long time.Thereby the water tank that a large amount of chilled waters are housed need to isolate for a long time with external environment usually, prevents that external substance or biology from entering the cooling water tank polluted water.When Passive containment cooling system puts into operation, cooling water tank must with external environment UNICOM, discharged steam.This means that Passive containment cooling system needs the gas discharging apparatus with long term seal function.
Publication number is in the patent document of CN01235243.8, and the principal character of disclosed " a kind of water sealed tank of automatic water supplement " is to utilize mechanism's automatic liquid level controls such as ball float to realize water seal; The patent No. is: US8,161,732, name is called in the patent document of " System and method for control of gas emissions from oil storage vessel ", has narrated gaseous tension in a kind of pressure vessel that crude oil is housed for control and the method and apparatus of discharging thereof.
Summary of the invention
The object of the present invention is to provide a kind of be applicable to must with the self-starting gas discharging apparatus of the long-term water seal resistance of band of the exhaust of the long-term spacing container of external environment.
The object of the present invention is achieved like this:
Comprise U-shaped gas discharge pipe 1, filling pipe 2, header tank 3, recirculatory pipe 4, U-shaped gas discharge pipe 1 one ends with need to be connected with the headroom of the water tank 8 of environment isolation, the other end stretches into header tank 3 from the bottom and be in vertical layout, one end of return pipe 4 is connected with the bottom of header tank 3, the other end is connected in water tank 8 and be positioned under liquid level 7, and an end of filling pipe 2 is connected with the bottom of U-shaped gas discharge pipe 1, the other end is connected with return pipe 4.
The present invention can also comprise that the first reverse checkvalve 5 and the second reverse checkvalve 6, the first reverse checkvalves 5 are arranged on return pipe 4, and the second reverse checkvalve 6 is arranged on filling pipe 2.
Also flow-limiting valve can be set on filling pipe 2 and return pipe 4.
For the requirement of the long-term isolation of Passive containment cooling system and emission gases, the present invention has designed a gas discharging apparatus with long-term water seal resistance.It mainly is comprised of gas discharge pipe, filling pipe, header tank, recirculatory pipe and 2 reverse checkvalves.Gas discharge pipe adopts the U-shaped pipeline, and it utilizes the U-shaped structure can form water seal to seal the water tank that needs with the environment isolation.The part pipeline that the U-shaped gas discharge pipe utilizes filling pipe and recirculatory pipe is communicated with water body in water tank; This makes its water seal resistance can because evaporation of water in water seal lost efficacy, not realize the long-term isolation of water tank and external environment.When the gas of discharging when carrying large water gaging leaving water case secretly, header tank the recyclable water of being carried secretly by air-flow is set, and by recirculatory pipe, the water that reclaims is delivered to water tank.
When produce in water tank or during receiver gases, the pressure in water tank rises thereupon.The water seal that utilizes the pressure reduction between water tank and external environment can open the U-shaped gas discharge pipe.Because filling pipe is connected with the interior water body of water tank 8 with return pipe 4, therefore before water seal was opened, along with the rising of water tank internal pressure, the water of water tank may be discharged from water tank by filling pipe and return pipe.In order to prevent the loss of water in water tank, on filling pipe and return pipe, reverse checkvalve is set.Can realize the smooth opening of water seal and effective recovery of backwater by these two reverse checkvalves.
The present invention has following characteristics:
1. water seal has long-term effectiveness.Utilize the water loading amount in filling pipe and water tank to realize the permanently effective of long-term water supplement function and water seal.
2. keeping with open fully need not manual operation of water seal, have non-active feature completely.Whole gas discharging apparatus does not adopt any active parts, only relies on simple pipeline and valve to complete long-term isolation and the gas discharging function of water tank and environment.
3. sealing structure for water has the backwater collecting function, reduces the unnecessary loss of water loading amount in water tank.
Description of drawings
The long-term water seal resistance self-starting of Fig. 1 band gas discharging apparatus structural drawing.
Embodiment
Below in conjunction with Fig. 1, for example the present invention is done more detailed description: the self-starting gas discharging apparatus with long-term water seal resistance comprises U-shaped gas discharge pipe 1, filling pipe 2, header tank 3, recirculatory pipe 4, reverse checkvalve 5 and reverse checkvalve 6.U-shaped gas discharge pipe 1 one ends with need to be connected with the headroom of the water tank 8 of environment isolation, the other end stretches into header tank 3 and is in vertical layout from the bottom.U-shaped gas discharge pipe 1 endpiece is arranged to the water that vertical state can utilize gravity that gas and its are carried secretly to be separated.One end of return pipe 4 connects and is connected with the bottom of header tank 3, and the other end is connected in water tank 8, and this end must be positioned under liquid level 7.Such design not only can be carried header tank 8 with the water that header tank 3 is collected, and can provide the water source for water seal.One end of filling pipe 2 is connected with the bottom of U-shaped gas discharge pipe 1, and the other end is connected to realize its water supplement function with return pipe 4.
Pressure in water tank 8 is higher than environmental pressure but before water seal do not open, the non-return valve 5 on return pipe 4 can stop the water in water tank 8 to be discharged from water tank 8 by return pipe 4; Non-return valve 6 on filling pipe 2 can stop the water in water tank 8 to be discharged from water tank by filling pipe 2 and gas discharge pipe 1.
After water seal was unlocked, along with the falling of the pressure in water tank 8, the water in header tank 3 can be back in water tank 8 by return pipe 4; Under the effect of pressure reduction between return pipe 4 and gas discharge pipe 1, the non-return valve 6 on filling pipe 2 can stop the water in water tank 8 to be discharged from water tank by filling pipe 2 and gas discharge pipe 1.
Flow-limiting valve also can be set with unlatching and the serviceability of adjusting gear on filling pipe and return pipe.
