Problems solved by technology

[0017] In addition, in the oil separator disclosed in Patent Document 4, since the partition plate is not provided, the lubricating liquid separated from the compressed gas flowing into the frame scatters much, and the separation efficiency decreases.
[0018] In addition, in the structure utilizing the centrifugal separation effect, in order to improve the separation efficiency, the vertical length of the frame needs to be increased, resulting in an increase in the cost of the lubricating liquid separator itself, and the compressor main body and the lubricating liquid separating device are arranged in one housing There is also a problem with isochronous space
[0019] In addition, as disclosed in Patent Document 1, disposing the demister on the inner side of the partition plate increases the pressure loss and reduces the efficiency of the gas compressor. The noise reduction effect of the demister, and the original function of the demister cannot be realized

no. 1 approach 〕

[0043] according to figure 1 The lubricating liquid separator 1 according to the first embodiment of the present invention will be described.

[0044] (Structure of Lubricating Liquid Separator 1)

[0045] The lubricating liquid separator 1 and an unillustrated compressor main body constitute a part of a gas compressor. Lubricating fluid separator 1 such as figure 1 As shown, it has a cylindrical frame body 2 . The housing 2 is made of metal or pressure-resistant resin. In addition, the frame body 2 is installed in a state erected in the vertical direction (longitudinal direction). In addition, the frame body 2 is not limited to a cylindrical shape, and may be elliptical or polygonal. The frame body 2 has a compressed gas inlet 3 on its side wall. In addition, a lubricating fluid reservoir 8 is provided at the bottom inside the housing 2 .

[0046] The compressed gas inflow port 3 is connected to a not-shown discharge port of the compressor main body via a gas inflow pi...

[0068] Then according to image 3 The lubricating liquid separator 21 of the second embodiment will be described.

[0069] (Structure of Lubricating Liquid Separator 21)

[0070] In the second embodiment, the lubricating liquid separation device 21, such as image 3 As shown, the point that the demister 26 is provided in the side wall of the housing|casing 2 at the part facing the partition plate 5 differs from 1st Embodiment.

[0071] Such as image 3 As shown in (a), the lower end of the demister 26 is positioned below the lower end of the partition plate 5 . In addition, the lower end of the demister 26 may be positioned at the same height as the lower end of the partition plate 5 . Additionally, if image 3 The A-A profile of (a) is image 3 As shown in (b), the demister 26 is arranged without covering the compressed gas inlet 3 . As a result, the pressure pulsation of the compressed gas swirling in the flow path 10 formed between the partition plate 5 and the porti...

no. 3 approach 〕

[0082] Next, according to Figure 4 A lubricating liquid separator 31 according to a third embodiment of the present invention will be described.

[0083] (Structure and Operation of the Lubricating Liquid Separator 31)

[0084] In the third embodiment, the lubricating liquid separation device 31, such as Figure 4 As shown, the demister 6 is provided on the outer surface side of the partition plate 5, and the demister 26 is provided on the side wall of the frame body 2 at a position opposite to the partition plate 5, which is different from the first and second embodiments. different ways.

[0085] Such as Figure 4 As shown in (a), the lower end of the demister 26 is positioned below the lower end of the partition plate 5 . In addition, the lower end of the demister 26 may be positioned at the same height as the lower end of the partition plate 5 . Additionally, if Figure 4 The A-A profile of (a) is Figure 4 As shown in (b), the demister 26 is arranged without cover...

Abstract

A lubricating liquid separator is disclosed which can damp a compressor pulsation noise effectively and improve the lubricating liquid separating performance without greatly enlarging the size of the separator itself. A demister (6) having a sound absorbing performance is disposed on an outer periphery side of a partition plate (5). Compressed gas which enters the interior of a housing (2) through a compressed gas inlet port (3) flows as rotating flow in a flow path (10) formed between the partition plate (5) and a portion of a side wall of the housing (2) opposed to the partition plate (5). Pressure pulsation of the compressed gas is diminished by the demister (6), and a compressor pulsation noise induced by the rotating flow of the compressed gas is diminished by the sound absorbing performance of the demister (6). Further, with the demister (6), reflection of the compressed gas at a wall surface of the partition plate (5) is suppressed, and scattering of lubricating liquid separated from the compressed gas is suppressed.

Description

technical field [0001] The present invention relates to a lubricating liquid separation device for separating and recovering lubricating liquid from compressed gas used in oil-cooled air compressors, refrigerators, gas compressors, water-lubricating air compressors and the like. Background technique [0002] In screw type or scroll type air / gas compressors, refrigerators, etc., liquids such as oil or water are used as lubricants and rotor coolants when the rotors of the compression section come into contact with each other. These gas compressors are equipped with a lubricating liquid separator for separating and recovering the lubricating liquid from the compressed gas in order to discharge the compressed gas mixed with the lubricating liquid (lubricating liquid). [0003] The lubricating fluid separation device is called an oil recovery device or an oil separator when the lubricating fluid is oil, and is called a water recovery device or a water separator when the lubricati...
