る。Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a process-type centrifugal compressor that primarily handles hydrocarbon gas such as natural gas, and in particular to shaft sealing under operating conditions where non-flammable gas cannot be used. The present invention relates to a structure of a degassing tank suitable for separating oil and process gas molten in shaft seal oil.

。Conventionally, in process-type centrifugal compressors, the structure of the decasing tank, in which nonflammable gas is not available and the shaft seal oil and process gas are separated by stirring, has partitions 1 and 2 as shown in Figure 2. The structure was such that the shaft seal oil and process gas chambers were separated. A related device of this type is, for example, Japanese Patent Publication No. 53-3456.

６に流出していき。In the above conventional technology, as shown in FIG. 2, the oil containing the process gas stirred by the stirrer 8 forms a vortex in the contaminated oil chamber 4 due to the stirring, and is not sufficiently separated from the process gas. The oil passes between the partitions 1 and 2 and flows into the clean oil chamber 6.
油が一定時間タンク内に滞留しない為、デガシングタン
クの機能が充分得られない構造となっていた。Because the oil does not remain in the tank for a certain period of time, the structure of the degassing tank does not function satisfactorily.
即ち、プロセスガスと軸封用油の分離を助長する為に設
置した撹拌８８が作り出す渦流によって。That is, by the vortex created by the stirring 88 installed to promote separation of the process gas and shaft sealing oil.
油が、汚染油室４内に滞留する時間が短かいまま清浄油

た。There is a problem that occurs as a side effect that the oil remains in the contaminated oil chamber 4 for a short time before flowing out into the clean oil chamber 6.

セスガスは、ベント１７を通って大気中に放出される。A partition plate 3 installed in the degassing tank is divided into a contaminated oil chamber 4 for storing contaminated oil and a clean oil chamber 6 for storing clean oil, which is separated from the process gas. The vortex flow prevents the oil from passing through the partitions 1 and 2, and the newly supplied oil prevents the oil from passing through the partitions 1 and 2.
It operates so that only the oil that overflows the partition 3 due to the rise in the liquid level in the contaminated oil chamber 4 can be sent to the intermediate oil chamber 5. [Example] Hereinafter, an embodiment of the present invention will be described with reference to FIG. When the liquid level becomes higher than the partition 3, the oil passes through the partition 3 and flows into the intermediate oil chamber 5. Inflow. Furthermore, when the liquid level in the intermediate oil chamber 5 becomes higher than the partition 2, the clean oil chamber 6
As a result, only the clean shaft sealing oil that has been separated from the process gas flows out from the oil outlet nozzle 11. Now, the oil in the contaminated oil chamber 4 is heated by a normally provided heater (composed of a steam pipe 12, a steam inlet, an outlet nozzle 13, 14, and a heater chamber 15 isolated from the degassing tank) and connected. The process gas is connected to the motor 10 by the rod 9 and is separated from the process gas which melts when it comes into contact with the process gas in the compressor due to stirring by the stirrer 8. The separated process gas passes through the vent 17 to the atmosphere. released inside.
一方、清浄な油は、出口ノズル１１を通って流出し再び
図示しないタンクに集積したのち、軸封用油として再使
用されるに至る。On the other hand, the clean oil flows out through the outlet nozzle 11 and accumulates in a tank (not shown) again, after which it is reused as shaft sealing oil.
本実施例によると、撹拌器８の撹拌によって汚染油室４
内に形成される渦流は、油とプロセスガスとの分離効率
を上げる為に寄与する。従って。According to this embodiment, the contaminated oil chamber 4 is
The vortex formed within contributes to increasing the separation efficiency of oil and process gas. Therefore.
第２図に示す如く渦流が直接仕切り１及び２の間を通っ
て、清浄油室６内に流れ込むという不具合は解消される
。The problem that the vortex flow directly passes between the partitions 1 and 2 and flows into the clean oil chamber 6 as shown in FIG. 2 is eliminated.
本実施例のその他の特徴として、仕切り２の高さを仕切
り３に比べて少し低くすることによって汚染油室４内の
液面上昇によって流出してきた油を、中間油室５内に更
に滞留する時間をとり、プロセスガスとの分離を助長す
ることができる。Another feature of this embodiment is that by making the height of the partition 2 a little lower than that of the partition 3, the oil that has flowed out due to the rise in the liquid level in the contaminated oil chamber 4 is further retained in the intermediate oil chamber 5. This can take time and facilitate separation from the process gas.
本発明によれば、汚染油室内の液面が上昇してオーバー
フローする油のみ中間室へ流出させる仕切を設けるよう
にしたので、最適に軸封用油とプロセスガスの分離が可
能になる。According to the present invention, since the liquid level in the contaminated oil chamber rises and a partition is provided to allow only overflowing oil to flow out into the intermediate chamber, it is possible to optimally separate the shaft sealing oil and the process gas.
