  The present invention relates to a gas-liquid separator used for an oil-cooled compressor or the like.

  The gas-liquid separation device is a device that separates discharge gas containing oil from oil, for example, from an oil-cooled compressor. An oil separator that separates discharged gas and oil plays an important role as a part of the configuration of an oil-cooled compressor used in an air conditioner, for example. However, a large noise is generated when the discharge gas flows into the oil separator. For this reason, the entire air conditioner is regarded as a noise source.

Japanese Patent No. 2935815

  In the method described in Patent Document 1, a sound absorbing material made of a fiber material is adopted, and a sound deadening principle for absorbing and attenuating sound waves is used. For this reason, the frequency band of sound waves that can be silenced is high, and the frequency band that can be effectively silenced is around 500 Hz, and it is difficult to reduce the low-frequency pulsating sound generated by the inflowing gas. Moreover, in the method described in patent document 1, the muffling part is provided in the center part of the oil separator. For this reason, it becomes difficult to ensure a sufficient effective volume for the oil reservoir of the oil separator, and it is not possible to ensure a sufficient effective volume for the oil reservoir unless the size is increased. Furthermore, there are problems such as high cost of the apparatus and large installation space.

  An object of the present invention is to provide a gas-liquid separation device for a compressor that secures a sufficient effective volume for a liquid reservoir and effectively enables noise reduction.

Means and effects for solving the problems

  In order to solve the above problems, a gas-liquid separation device for a compressor according to the present invention includes a container that forms an internal space in which a separated liquid is held in a lower portion, a liquid that opens above the internal space and that is supplied from the compressor. A gas inflow portion that discharges gas containing gas to the internal space, a gas outflow portion that opens above the internal space and discharges gas from the internal space, a liquid outflow portion that opens below the internal space and allows liquid to flow out, The gas-liquid separation device has a gas-liquid separation means at the gas inflow portion, and a muffler means above the internal space. Since the gas-liquid separation means is provided in the gas inflow portion and the muffling means is provided above the internal space, a space as a liquid reservoir is provided below the gas-liquid separation device and noise can be effectively reduced.

  Further, in the internal space of the gas-liquid separation device of the compressor of the present invention, the gas inflow portion has a first tubular portion and a first opening, and the gas outflow portion has a second opening. preferable.

  According to the gas-liquid separation device of the compressor of the present invention, the gas containing liquid is directly flowed to the separation means provided in the gas inflow portion of the gas-liquid separation device, and high gas-liquid phase separation efficiency is expected. Can do. In addition, since the gas-liquid separation device of the compressor of the present invention is provided with a noise reduction means above the internal space, noise generated by the airflow can be reduced. Further, the noise reduction means according to the present invention includes: Since it is installed above the internal space of the gas-liquid separator, the space above the internal space of the container is effectively utilized, and an effective volume for storing the liquid of the gas-liquid separator of the compressor is ensured while providing a silencer. be able to. That is, as compared with the gas-liquid separator of the conventional compressor, the current volume of the gas-liquid separator can be maintained while having the sound deadening means.

  The silencer of the gas-liquid separation device of the compressor according to the present invention includes a partition that divides an internal space into an upper resonance chamber and a lower gas-liquid separation chamber, and a resonance chamber provided in the first tubular portion. It is preferable that a plurality of resonance openings be opened. The internal upper space of the gas-liquid separation device is a resonance chamber, and is formed behind the resonance opening through the resonance opening of the first tubular portion with respect to the natural frequency of the noise sound wave generated by the gas flowing through the gas inflow portion. A resonance absorption action is caused in the resonance chamber, the incident sound having the same frequency is absorbed, and the sound pressure of the noise sound wave can be reduced. In particular, the gas-liquid separation device of the compressor according to the present invention has a remarkable sound absorption effect for low noise with a large middle sound.

  Further, the silencer of the gas-liquid separation device of the compressor of the present invention forms an expansion chamber and a partition that divides the internal space into at least two expansion chambers located above and a gas-liquid separation chamber located below. An expansion chamber opening that communicates each expansion chamber with the partition, and a gas-liquid separation chamber opening that communicates the expansion chamber and the gas-liquid separation chamber with the partition that partitions the expansion chamber and the gas-liquid separation chamber. It is preferable that the gas outflow portion and the gas outflow portion are communicated with each other via at least two expansion chambers. The expansion chamber opening of the gas-liquid separation device of the compressor of the present invention has a first projecting tubular portion that is formed integrally with the partition wall and protrudes on both sides of the partition wall to open to the expansion chamber. It is preferable that the part has a second projecting tubular part formed integrally with the partition wall and projecting on both sides of the partition wall and opening into the expansion chamber and the gas-liquid separation chamber. While sound waves generated by the gas flowing into the expansion chamber are reflected by the expansion chamber walls, gas expansion and contraction effects can be obtained in the expansion chamber space, resulting in a reduction in the sound pressure of the noise. it can. Furthermore, the noise generated by the gas flow can be further effectively reduced by configuring the expansion chamber opening and the gas-liquid separation chamber opening with sound absorbing members.

  Further, the silencer of the gas-liquid separator of the compressor according to the present invention includes a partition that divides the internal space into a silencer chamber located above and a gas-liquid separation chamber located below, and the gas in the container disposed in the partition. A check valve that flows in a single direction from the gas-liquid separation chamber to the muffler chamber is preferable. Since the check valve is disposed between the silencer chamber and the gas-liquid separation chamber, the gas flow is rectified by the check valve, and the sound pressure of the noise sound wave is suppressed. Further, the sound pressure of the noise sound wave can be reduced by the reflection action of the noise sound wave in the muffler room.

  The silencer of the gas-liquid separator of the compressor according to the present invention includes a second tubular portion provided in the gas outflow portion, and is integrally formed with the second tubular portion and opens into the gas-liquid separation chamber. It is preferable that the second opening and the first opening are arranged in the opposite direction or vertically. The sound wave generated by the airflow flowing from the gas inflow part is a mechanism that attenuates noise by reflecting the sound level of the liquid stored in the bottom of the container of the gas-liquid separator and reflecting the sound wave with the inner wall surface of the container. . Since the first opening portion of the gas inflow portion is disposed in the direction opposite to the second opening portion of the gas outflow portion, the number of reflections of the noise sound wave is increased inside the container, and the sound absorbing effect can be further enhanced. Further, the same sound absorbing effect can be obtained even when the first opening of the gas inflow portion and the second opening of the gas outflow portion are arranged vertically. Thus, by making the arrangement relationship between the first opening and the second opening opposite or perpendicular, the noise sound wave can increase the number of reflections in the container, and the noise sound wave can be reduced by reflection. Can do.

  Moreover, it is preferable that the muffling means of the gas-liquid separator of the compressor of the present invention is constituted by a rectifying means that is provided in the second opening of the gas outflow portion and is made of a porous member having air permeability. Since the second opening is provided with a rectifying means made of a porous member having air permeability, the air flow is adjusted when the flow of the gas flowing in the internal space of the gas-liquid separator passes through the hole of the porous member. Therefore, the accompanying noise and sound pressure can be reduced.

  Further, the silencer of the gas-liquid separator of the compressor according to the present invention is configured by an airflow channel diameter control unit that is provided inside the first tubular portion and controls the channel diameter of the airflow, and the airflow channel diameter control unit is the first airflow channel diameter control unit. It is preferable to have a third opening having an inner diameter smaller than the tubular portion. Since the air flow channel diameter control means is provided with the third opening having an inner diameter smaller than the first tubular portion of the gas inflow portion, the entire container becomes an expansion chamber, and noise is caused by expansion and contraction of the gas flowing through the gas inflow portion. Sound pressure can be reduced.

  As described above, the gas-liquid separator of the compressor of the present invention effectively improves the silencing function by efficiently using the upper part of the inner space of the container, and at the same time, the entire apparatus is not increased in size and efficiency. Gas-liquid separation can be realized.
