波の圧力脈動を有する流体機械に好適な、吸音式消音器
を冷却器の後方に備えた流体機械に関する。Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a fluid machine that requires a silencer, and is applicable to fluid machines that have a high discharge gas temperature and high-frequency pressure pulsations, such as dry screw compressors. The present invention relates to a fluid machine equipped with a sound absorbing muffler behind a cooler, which is suitable for the machine.

いは消音器一式を交換する方式を採用していた。It was installed behind the cooler. In addition, as this muffler, for example, as shown in Japanese Utility Model Publication No. 51-33374, a muffler with a replaceable sound absorbing part may be used in order to reduce the sound reduction effect due to dirt or moisture adsorption on the muffler's sound absorbing part. Alternatively, a method was adopted in which the entire set of silencers was replaced.

た。When installed behind the cooler as in the prior art described above, the condensed water generated by the cooler cannot be completely separated by the drain separator, and some of the condensed water is separated by the drain separator. There is a problem in that the condensed water is adsorbed by the sound absorbing part of the muffler at the rear of the cooler, and furthermore, the noise reduction effect of the muffler is significantly reduced due to dust contained in the gas. To deal with this problem, the above-mentioned conventional technology does not take into account the fundamental problem of preventing the deterioration of the sound reduction effect, and simply replaces the muffler, which is a common problem. However, the problem of a decline in the sound reduction effect remained.
本発明の目的は、減音効果の低下を防止することおよび
、高温でかつ高周波の圧力脈動を有する吐出ガスによる
消音器の吸音部破損を防止することにある。An object of the present invention is to prevent the sound reduction effect from deteriorating and to prevent damage to the sound absorbing part of a muffler due to discharged gas having high temperature and high frequency pressure pulsations.

In order to prevent damage to the sound absorbing part due to high temperature and high frequency pressure pulsations, this is achieved by protecting the sound absorbing part with stainless steel cloth that has high strength at high temperatures.
消音器は、冷却器の前段に設置されているため、冷却器
で発生する凝縮水により、消音器の吸音部が濡れ、減音
効果が低下することがない、また。Since the muffler is installed before the cooler, the sound absorbing part of the muffler will not get wet due to condensed water generated by the cooler, and the sound reduction effect will not deteriorate.

で凝縮水とガスを完全に分離し。Fig. 1 shows an embodiment of the present invention. In this figure, gas is compressed by a compressor 1 to become high temperature and high pressure gas, but in a dry screw compressor, pressure pulsations of even higher frequency occur. It becomes a gas with . Conventionally, this gas flows into a cooler where it is cooled and
The pressure pulsations are damped due to the reduced flow rate and pressure loss in the cooler. Moreover, moisture in the gas is condensed by cooling. Conventionally, the gas then flows into a drain separator along with the condensed water, and the condensed water and gas are separated. However, this drain separator completely separates condensed water and gas.

が破損することはない。It is impossible to send only the gas backwards, and generally several tens of percent of the condensed water flows backwards together with the gas. When this gas flows into the muffler provided at the final stage, the condensed water in the gas is adsorbed by the sound absorbing part of the muffler, so that the sound absorbing part gets wet and the sound reduction effect of the muffler 2 is reduced. Furthermore, when the sound absorbing section becomes wet, dust contained in the gas tends to adhere to the sound absorbing section, which further reduces the sound reduction effect. Therefore, in the present invention, the muffler 2 is installed before the cooler 3, in other words, after the compressor 1. Therefore, gas that does not contain condensed water flows into the silencer 2, and the sound reduction effect does not deteriorate. Gas with high frequency pressure pulsations will flow in. Therefore, as shown in FIG. 2, the sound absorbing material 6 of the silencer 2 is a stainless steel cloth 5.
Because it is covered by and protected from gas, the sound absorbing material 6
will not be damaged.

め、消音器の交換が不要となり。According to the present invention, it is possible to prevent the sound reduction effect of the muffler from deteriorating and also to prevent damage to the sound absorbing section, so that the muffler does not need to be replaced.
その経済的効果は大である。The economic effect is significant.
