すなわち上記のシールポツトは、タンク内が加圧
状態にあるときは作動するが、タンク内の負圧に
は作動しない欠点がある。 In this type of seal pot, if the above-mentioned seal operation device fails while the liquid is being transferred by the pump, the inside of the tank will become under negative pressure. Then, the seal water in the seal pot is gradually drawn into the inlet nozzle c, and as a result, there is a risk that the tank will buckle.
That is, the above-mentioned seal pot operates when the inside of the tank is pressurized, but has the disadvantage that it does not operate when the inside of the tank is under negative pressure.
そこで、タンク内の負圧によつても作動させる

いなくても良い。 The partition plate 9 between the upper water tank 1 and the lower water tank 2 includes a drain pipe 10 of the upper water tank, and a communication pipe 11 extending between the gas phase part of the upper water tank 1 and the liquid phase part of the lower water tank 2.
Also provided is an overflow pipe 12 for keeping the liquid level in the upper water tank 1 constant. An adjustment nozzle 13 that is slidable in the vertical direction is provided at the tip of the communication tube 11. The underwater depth of the communication pipe 11 becomes the operating pressure for pressurizing the tank. The overflow pipe 12 is provided to keep the water level in the upper water tank 1 constant and to supply seal water to the lower water tank 2. Further, the underwater portion of the overflow pipe 12 in the lower water tank 2 needs to be larger than the above. A drain nozzle 15 is installed on the bottom plate 14 of the lower water tank 2.
However, the side plate 16 is provided with a gas discharge pipe 17, and the side plate 17 is provided with a seal water overflow nozzle 18. It is preferable to provide a water washing mechanism 20 near the outlet of the nozzle 17 for the purpose of washing the gas.

用しなくても良い。 When the water washing mechanism 20 is used, it is not necessary to use the nozzle 8 of the upper water tank 1 if seal water is supplied from the nozzle 19.
本考案のシールポツトは、次のように作動す
る。 The seal pot of the present invention operates as follows.
タンク内圧は、常時、上部水槽１の室内に作用

き、排気ガスは、大気中に排気される前に水洗機
構２０によつて水洗される。 The tank internal pressure acts inside the upper water tank 1 at all times. When the internal pressure of the tank exceeds the set pressure, the positive pressure is applied to the seal water 22 of the upper water tank 1.
It acts on the liquid level and also acts on the seal water 22 in the communication pipe 11 through the communication pipe 11. As the internal pressure of the upper water tank 1 increases, the liquid level of the seal water 22 in the upper water tank 1 decreases, and the liquid level in the atmosphere suction communication pipe 5 rises accordingly. On the other hand, the liquid level of the seal water 22 in the lower water tank 2 rises due to the pressure acting on the liquid level of the seal water 22 in the communication pipe 11 through the communication pipe 11, but the rising seal water 22 passes through the seal water overflow nozzle 18. Drained. In this way, the liquid level in the communication pipe 11 becomes lower than the liquid level at the set pressure, so that the gas in the tank is discharged into the lower water tank 2 through the communication pipe 11. The gas discharged into the lower water tank 2 enters the chamber of the lower water tank 2 via the seal water 22 and is discharged through the gas exhaust pipe 17. At this time, the exhaust gas is washed with water by the water washing mechanism 20 before being exhausted into the atmosphere.
次に、タンク内圧がセツト圧以下になると、そ
の負圧は上部水槽１のシール水２２液面に作用す
ると共に連通管１１を通して連通管１１内のシー
ル水２２に作用する。 Next, when the tank internal pressure becomes lower than the set pressure, the negative pressure acts on the liquid level of the seal water 22 in the upper water tank 1 and acts on the seal water 22 in the communication pipe 11 through the communication pipe 11.
上部水槽１のシール水２２は上部水槽１の内圧
が下がり負圧になることによつて、大気吸引用連
通管５内のシール水２２の液面は下がる。これに
応じて水槽１内のシール水２２液面は上昇する
が、上昇分のシール水２２はオーバーフロー管１
２を通して下部水槽２内にオーバーフローする。 As the internal pressure of the upper water tank 1 decreases and the seal water 22 in the upper water tank 1 becomes negative pressure, the liquid level of the seal water 22 in the atmosphere suction communication pipe 5 lowers. Accordingly, the liquid level of the seal water 22 in the water tank 1 rises, but the increased seal water 22 is transferred to the overflow pipe 1.
2 and overflows into the lower water tank 2.
一方、連通管１１を通して下部水槽２内に作用
する負圧によつて、連通管１１内のシール水２２
液面は上昇する。これによつて、水槽２内のシー
ル水２２液面は下がることになるが、オーバーフ
ロー管１２を通してオーバーフローする上部水槽
１からのシール水２２によつて水位は一定に保た
れる。 On the other hand, the seal water 22 in the communication pipe 11 is caused by the negative pressure acting in the lower water tank 2 through the communication pipe 11.
The liquid level rises. As a result, the liquid level of the seal water 22 in the water tank 2 is lowered, but the water level is kept constant by the seal water 22 from the upper water tank 1 overflowing through the overflow pipe 12.
こうして、連通管１１内のシール水２２液面が
上昇し、大気吸引用連通管５内のシール水２２液
面が下降することによつて、大気中の空気は、大
気吸引用連通管５から上部水槽１の室内に入り、
タンク内の圧力を一定に保つことになる。 In this way, the liquid level of the seal water 22 in the communication pipe 11 rises and the liquid level of the seal water 22 in the atmosphere suction communication pipe 5 falls, so that air in the atmosphere is removed from the atmosphere suction communication pipe 5. Enter the upper aquarium 1 room,
This will keep the pressure inside the tank constant.
第３図に示すものは、ガス排出管１７を大気吸
引用連通管５内に挿入した形式のもので、その作
用は、第２図に示すものと同じである。 The one shown in FIG. 3 is of a type in which a gas exhaust pipe 17 is inserted into the atmosphere suction communication pipe 5, and its function is the same as that shown in FIG. 2.
