た。[Prior Art] It is known that an isothermal compressor is generally employed as a compressor for raw air in air separation equipment plants and the like. This isothermal compressor is constructed as shown in FIG. The upper part of the - line in FIG. 3 shows an axial longitudinal cross-sectional view of the isothermal compressor, and the lower part shows an axial cross-sectional view. As shown in the figure, a multi-stage impeller c is attached to a rotating shaft b of an isothermal compressor a. A pair of intercoolers d are installed on both sides between the stages of these impellers c. When these intercoolers d compress the compressed fluid and increase the pressure, the temperature also increases, so
This is for cooling the fluid to be compressed in order to increase compression efficiency. Mist is generated along with this cooling, and mist separators e are provided downstream of these intercoolers d to collect the mist generated in the intercoolers d. Conventionally, these mist separators e are shown in FIGS. 4 and 5.
It was constructed as shown in the figure. As shown,
The mist separator e includes a rectangular frame f shaped so that the direction of gravity is the longitudinal direction, a vane g disposed within the frame f along the direction of gravity, and a central part and a bottom part in the direction of gravity. gutters h and i installed in
It consisted of a discharge port j provided in the bottom gutter i for discharging the collected mist guided into the gutter h and i. The tip k of the vane g on the downstream side in the flow direction is bent and shaped to easily collect mist. In addition, the above-mentioned gutter h, i is a vane g
The mist collected at is guided to the above-mentioned outlet j to be discharged to the outside of the device to prevent re-scattering.
[考案が解決しようとする問題点]
ところで、従来の等温圧縮機用ミストセパレー

あるという問題があつた。 The mist collected by the vane g descends along the vane g due to gravity, and the amount of mist collected in substantially the lower half of the mist separator e increases. Also, gutter h
Since there is a wide distance between the mist and i, it takes time for the mist to be guided into the gutter h and i, and the mist ends up staying on the vane g. Therefore, there is a problem that the mist collection ability may be reduced or the collected mist may be scattered again.
さらに、重力方向においてミスト濃度の分布に

A mesh member is provided to cover this, and a gutter is provided in multiple stages in the direction of gravity to guide the mist collected by the vanes to the discharge port, and is arranged below the point where the suction flow velocity is high on the downstream side of the vanes. By installing gutters in multiple stages in the direction of gravity, mist (drain) is efficiently guided to the discharge port without reducing the mist collection ability, and by providing a mesh member, it is possible to recycle the collected mist. It can prevent scattering.

によつて排出口7に導かれるように成つている。 A mist separator for a compressor according to the present invention is shown in FIGS. 1 and 2. As shown in the figure, the frame 2 of the mist separator 1 is formed into a rectangular shape so that the direction of gravity is the longitudinal direction. Vanes 3 are disposed throughout the frame 2 along the direction of gravity. The tip 4 of the vane 3 on the downstream side in the flow direction is bent and shaped to easily collect mist. A mesh member 5 is provided on the downstream side of the vane 3 in the flow direction so as to cover the lower part of an impeller (not shown) where the suction flow velocity is high. Specifically, the mesh member 5 is attached to the downstream end edge of the frame 2 in the flow direction, and is located below (approximately the lower half) the point where the suction flow rate is high.
It covers vane 3 of. This mesh member 5 is formed of, for example, punched metal or wire mesh. Further, the frame body 2 is provided with gutter 6 in multiple stages in the direction of gravity below the portion where the suction flow velocity is high. For example, in the case where there are three gutters 6, these gutters 6 are installed so that the installation interval ratio is 2:3:4 in an upward direction with respect to the gutters 6 attached to the bottom of the frame 2 as a reference. The number of gutters 6 and the installation interval ratio are adjusted as appropriate depending on the equipment. A drain 7 is formed in the gutter 6 attached to the bottom.
The mist collected by the vane 3 is transferred to these gutter 6.
It is configured such that it is guided to the discharge port 7 by.
以上の如く構成された圧縮機用ミストセパレー
タ1の作用を述べる。 The operation of the mist separator 1 for a compressor constructed as described above will be described.
圧縮機用ミストセパレータは、その中央付近の
吸入流速が速く、その上部及び下部の流速が遅
い。これにより、中央付近でのミスト捕集が一番
多く、そのミストはドレンとなつて重力によりベ
ーンを上部から下部へと下降する。 In a mist separator for a compressor, the suction flow velocity is high near the center, and the flow velocity is slow at the upper and lower parts. As a result, most of the mist is collected near the center, and the mist becomes a drain and moves down the vane from the top to the bottom due to gravity.
そのためベーン3の略下半部のミスト濃度が上
昇する。しかし、本考案のミストセパレータ1は
その略下半分に樋を重力方向に多段に備えている
ので、あふれることなくドレンが効率よく排出口
へと導かれミストの捕集能力が低下することがな
い。 Therefore, the mist concentration in substantially the lower half of the vane 3 increases. However, since the mist separator 1 of the present invention is equipped with gutters in multiple stages in the direction of gravity in the lower half thereof, the drain is efficiently guided to the outlet without overflowing, and the mist collection ability is not reduced. .

響がない。 In addition, since the mesh member is provided at approximately the lower half of the mist separator 1, the suction flow velocity at approximately the lower half is restricted, so there is no fear that the collected drainage will scatter, and the re-scattering of the drainage is prevented. be able to. Moreover, since the low flow velocity in the lower part is restricted, the flow velocity of the entire mist separator is not affected much.
