Description of the Related Art Conventionally, oil-cooled compressors that use cooled lubricating oil for cooling, sealing, lubricating, etc. of gas compression parts have been widely used. Since this type of compressor injects oil into gas, an oil separator for separating the compressed gas and oil is required on the discharge side. This oil separator is interposed between the discharge port of the oil-cooled compressor and the oil tank, and has an inflow port for receiving a compressed gas accompanied by oil discharged from the discharge port and a gas-liquid separated It is generally provided with an oil outlet for guiding oil to the oil tank, a gas outlet for sending out compressed gas, and an oil separation element attached to the inlet of the gas outlet. The oil separation element is formed by densely gathering fine metal wires, specifically, a member made of the same material as a commercially available metal scrubber, or a filter called a demister. Known members are used as they are, or members formed by winding these members around the entire circumference of a tubular body having a large number of small holes in its side wall portion.

る。In the above conventional oil separator, the compressed gas accompanied by oil passes through the same filter member regardless of the position and direction of the oil separation element. It is like this. In other words,
In the conventional oil separation element, the flow path of compressed gas accompanied by oil is simply formed by a large number of non-linear small flow paths. For this reason, gas-liquid separation by the oil separation element is still insufficient, and improvement thereof is desired. The present invention has been made to solve the above-mentioned demands, and an oil-cooled compressor capable of improving the efficiency of separating oil from compressed gas accompanied by mist-like oil discharged from the compressor. It is intended to provide an oil separator.

The hollow body 25 with a collar, the grid-like plate-like body 26 that covers the outside of the upper half of the tubular body 22, and the thin wires that cover the outside of each of the plate-like body 26 and the lower half of the tubular body 22 are irregular. And an outer cylindrical body 27 formed in a cylindrical shape. Specific examples of the material of the cylindrical body 22 include punching metal and expanded metal. That is,
The cylindrical body 22 guides the enlarged oil droplets downward along the outer peripheral surface and causes the compressed gas to flow into the cylinder.

Each of the parts is made of a linearly formed member. That is, this plate-like body 26 is a member having a large number of linear portions in the downward direction that guide the oil droplets that have grown to a certain extent. The plate-like body 26 is provided so as to cover not the entire circumference of the cylindrical body 22 but the outer side of the upper half as described above. The outer cylinder 27 is made of the same material as the material of the conventional metal element described above, and is a so-called commercially available constituent material of a metal scourer, a member having a large number of small holes or small channels such as a filter member. Is formed in a tubular shape. That is, when the mixture of compressed gas and mist-like oil flows in, the outer cylinder body 27 captures this oil, and further, the mixture collides with many thin linear members which are obstacles. In the process of advancing inside the outer cylindrical body 27, the captured oil grows into oil droplets.

Then, even if the oil may flow into the cylinder, the oil may drip downward in the cylinder, or may hit the end surface of the cylinder 22 and drop from the lower portion of the cylinder 22, so that only the compressed gas is discharged from the gas outlet 13. It is easy to be sent out from. Further, the oil outlet 12 is provided at the bottom of the space where the oil separation element 14 is located, of the above-described two divided spaces. The oil tank 2 is configured such that the oil separated from the compressed gas by the oil separator 1 is temporarily stored in the lower oil sump 31 and the oil is discharged from the outflow part 32. In addition, in FIG. 1, compressed gas accompanied by mist-like oil flows from the discharge port of the compressor,
Is the outflow of compressed gas, for example in the case of a heat pump the outflow of compressed gas to a condenser, is the outflow of oil, for example through an oil cooler, an oil filter, the bearing of the compressor, the shaft seal and the gas compression space Shows the spill of oil into and enters.

は、主としてその上半分においてである。In the oil separator 1 having the above-described structure, the compressed gas accompanied by mist-like oil from the inflow port 11 is silencer 1.
After passing through 5, it flows into the oil separator 1. Then, the noise generated from the pulsating compressed gas decreases as the compressed gas passes through the silencer. The compressed gas further passes through the oil separation element 16, and a part of the oil is captured in the process of the compressed gas passing therethrough. This oil separation element 16
The oil captured by the oil gradually descends to the oil separation element 16
Collects at the bottom of the oil and flows toward the oil outlet 12.
This compressed gas further flows toward the oil separation element 14 and flows into the outer cylindrical body 27 so as to wrap around the outside of the end plate 23 that acts as an obstacle. And FIG.
As indicated by an arrow I, in the process of passing therethrough, the mist-like oil is trapped inside the outer cylindrical body 27, becomes an oil droplet, and gradually reaches the plate-shaped body 26 while gradually increasing. In the lower half of the outer tubular body 27, when the oil droplet becomes large, it does not reach the plate-shaped body 27, but partially starts to descend due to gravity.
That is, the oil droplets flow toward the inner peripheral side of the outer cylinder 27 mainly in the upper half thereof.

As indicated by, the compressed gas is guided downward along a linear portion extending in the downward direction of the plate-like body 26, and the compressed gas passes through the plate-like body 26 and reaches the cylindrical body 22. Even if the oil that passes through the plate-like body 26 remains, the oil that reaches the cylindrical body 22 is already a large oil droplet. Then, in the cylindrical body 22, the oil that has become an oil drop flows downward along the outer peripheral surface due to gravity,
As shown by the arrow III in FIG. 4, the gas is dropped and mainly the compressed gas passes into the cylindrical body 22. Further, the compressed gas is removed of oil as described above in the process of flowing out from the gas outlet 13 provided eccentrically from the center of the cylindrical body 22, and becomes a clean state. The oil separated from the compressed gas is temporarily stored in the oil tank 2 and then guided to the above-mentioned oil injection location in the compressor and used for circulation.

っている。As described above, the oil separator 1 has a structure in which the plate-like member 26 is provided in the upper half of the cylinder 22 between the cylinder 22 and the outer cylinder 27. The oil separation efficiency is good. Further, by including the oil separation element 16, the oil separation efficiency is further improved. Furthermore, conventionally, oil accumulates at the bottom of the oil separator,
The oil separation element was soaked in the oil and was easily unusable.
By providing the space in the lower part of the space on the gas outlet 13 side of the divided space, the situation of becoming unusable does not occur.
