PROBLEM TO BE SOLVED: To provide an oil-cooled compressor that effectively removes moisture in an oil tank.SOLUTION: The oil-cooled compressor for compressing gas while supplying oil to a compressor body 2 includes: an oil tank 3 for storing oil which is separated and recovered from the gas compressed by the compressor body 2; a moisture adsorption material 11 having one end positioned at the bottom inside the oil tank 3 and the other end positioned near a compressed gas outlet of the oil tank 3; and a heater 12 for heating the other end of the moisture adsorption material 11.

Description

この発明は、油冷式圧縮機に係るものである。特に圧縮機が有する油タンクにおける水分除去に関するものである。   The present invention relates to an oil-cooled compressor. In particular, the present invention relates to moisture removal in an oil tank of a compressor.

例えば、圧縮部分の冷却、潤滑、密封等を油（圧縮機油）を用いて行う油冷式圧縮機が従来からある。従来の油冷式圧縮機では、例えば、油タンク中の水分を、タンク下流の除湿された空気を油タンク内に導入させて除去している。具体的には、吸込み弁を閉鎖した無負荷運転時に、除湿空気を内気循環させる回路を形成し、油タンク中の水分を除去するものである（例えば、特許文献１参照）。   For example, there is a conventional oil-cooled compressor that uses oil (compressor oil) to cool, lubricate, seal, and the like of a compressed portion. In a conventional oil-cooled compressor, for example, moisture in an oil tank is removed by introducing dehumidified air downstream of the tank into the oil tank. Specifically, a circuit that circulates the dehumidified air in the inside air during the no-load operation with the suction valve closed is formed to remove water in the oil tank (see, for example, Patent Document 1).

特開平８−２１９０２４号公報（第５−６項、第１図）Japanese Patent Laid-Open No. 8-219024 (Section 5-6, FIG. 1)

上記の油冷式圧縮機における油タンク中の水分除去は、吸込み弁を閉鎖した無負荷運転ができることを前提に行うものである。このため、例えば無負荷運転を行うことができない油冷式圧縮機には適用することができない。   The water removal in the oil tank in the oil-cooled compressor is performed on the premise that no-load operation with the suction valve closed can be performed. For this reason, it cannot be applied to, for example, an oil-cooled compressor that cannot perform no-load operation.

この発明は、上記のような課題を解決するためになされたものであり、例えば無負荷運転等によらず、効率的に油タンク内の水分を除去できる油冷式圧縮機を得ることを目的とする。   The present invention has been made in order to solve the above-described problems. For example, an object of the present invention is to obtain an oil-cooled compressor that can efficiently remove moisture in an oil tank regardless of no-load operation or the like. And

この発明に係る油冷式圧縮機は、圧縮機本体に油を供給しながら気体を圧縮する油冷式圧縮機において、圧縮機本体が圧縮した気体から分離して回収した油を溜める油タンクと、一端が油タンク内側の底部に位置し、他端が油タンクの圧縮気体出口付近に位置するように配置した水分吸着材と、水分吸着材の他端部分を加熱するための加熱手段とを備える。このとき、水分吸着材は、水分のみを選択的に吸着するように調整されているとともに、加熱等により生じる気体の雰囲気の変化により吸着した水分を周囲の圧縮した気体に放出し、かつ一旦水分を放出した後は再度水分を吸着できる状態に再生される。   An oil-cooled compressor according to the present invention is an oil-cooled compressor that compresses a gas while supplying oil to the compressor body, and an oil tank that stores oil separated and recovered from the compressed gas by the compressor body; A moisture adsorbent disposed so that one end is located at the bottom inside the oil tank and the other end is located near the compressed gas outlet of the oil tank, and a heating means for heating the other end portion of the moisture adsorbent Prepare. At this time, the moisture adsorbing material is adjusted so as to selectively adsorb only moisture, releases moisture adsorbed by a change in the gas atmosphere caused by heating, etc., into the surrounding compressed gas, and once moisture After being released, it is regenerated so that moisture can be adsorbed again.

この発明によれば、油タンク内面に設けられた水分吸着材において、油中に浸った一端にて水分を吸着するとともに、気体出口付近の一端でのヒータの加熱により吸着されている水分が放出され、圧縮気体と共に油タンクの出口から排出されるように構成したので、通常の圧縮機動作中に、連続的に油タンク中の水分を油から分離し、タンク外に排出することができる。   According to the present invention, in the moisture adsorbing material provided on the inner surface of the oil tank, moisture is adsorbed at one end immersed in the oil and moisture adsorbed by heating the heater at one end near the gas outlet is released. Since it is configured to be discharged from the outlet of the oil tank together with the compressed gas, moisture in the oil tank can be continuously separated from the oil and discharged out of the tank during normal compressor operation.

実施の形態１．
図１は、この発明の実施の形態１である油冷式圧縮機の全体構成の模式図である。図１に示すように、本実施の形態の油冷式圧縮機は、エアフィルタ１、圧縮機本体２、油タンク３、油分離手段４、セパレータエレメント５、アフタークーラ６、水分離器７、エアドライヤ８、オイルフィルタ９およびオイルクーラ１０を有している。 Embodiment 1 FIG.
1 is a schematic diagram of an overall configuration of an oil-cooled compressor according to Embodiment 1 of the present invention. As shown in FIG. 1, the oil-cooled compressor of the present embodiment includes an air filter 1, a compressor body 2, an oil tank 3, an oil separation means 4, a separator element 5, an after cooler 6, a water separator 7, An air dryer 8, an oil filter 9, and an oil cooler 10 are provided.

エアフィルタ１は、油冷式圧縮機内に吸い込んだ空気等の気体（以下、空気とする）に含まれる粉塵等を捕捉する。圧縮機本体２は、吸入した空気を圧縮し、圧縮空気として送り出す。油分離手段４は、圧縮空気に含まれる油（冷凍機油）を圧縮空気から分離（一次分離）する。油タンク３は油分離手段４が分離した油を、圧縮機本体２に戻すために一時的に蓄えるタンクである。セパレータエレメント５は、油タンク３を通過した圧縮空気からさらに油をろ過分離する。アフタークーラ６はセパレータエレメント５を通過した圧縮空気を冷却する。また、水分離器７は、圧縮空気から凝縮される水を分離する、ドレン排出機能を有する。エアドライヤ８は圧縮空気を除湿する。そして、オイルフィルタ９は、油タンク３の油を浄化冷却し、圧縮機本体２に再度供給する。オイルクーラ１０は油を冷却する。   The air filter 1 captures dust and the like contained in a gas such as air (hereinafter referred to as air) sucked into the oil-cooled compressor. The compressor body 2 compresses the sucked air and sends it out as compressed air. The oil separation means 4 separates (primary separation) oil (refrigeration oil) contained in the compressed air from the compressed air. The oil tank 3 is a tank that temporarily stores the oil separated by the oil separation means 4 in order to return the oil to the compressor body 2. The separator element 5 further separates oil from the compressed air that has passed through the oil tank 3 by filtration. The aftercooler 6 cools the compressed air that has passed through the separator element 5. Moreover, the water separator 7 has a drain discharge function which isolate | separates the water condensed from compressed air. The air dryer 8 dehumidifies the compressed air. The oil filter 9 purifies and cools the oil in the oil tank 3 and supplies it to the compressor body 2 again. The oil cooler 10 cools the oil.

図２は実施の形態１の油冷式圧縮機に係る油タンク３の断面図である。図２に示すように、本実施の形態の油冷式圧縮機において、油タンク３は水分吸着手段となる水分吸着材１１を有している。水分吸着材１１は、一端が油タンク３の下部（側面下部）、底部等、油タンク３に溜まった油に浸漬できるような位置にあり、他端が、圧縮空気が送り出される圧縮空気出口の直前（圧縮空気出口付近）の位置にあって、一連なりになっている。また、油タンク３の外面から油タンク３の空気出口付近における水分吸着材１１の端部を加熱する加熱手段となるヒータ１２を有している。そして、圧縮機本体２が稼動（駆動）して圧縮空気が発生する直前から、圧縮機本体２の稼動が終了して内圧が開放されるまでの間、ヒータ１２に通電して加熱させるようにする。   FIG. 2 is a cross-sectional view of the oil tank 3 according to the oil-cooled compressor of the first embodiment. As shown in FIG. 2, in the oil-cooled compressor according to the present embodiment, the oil tank 3 has a moisture adsorbing material 11 serving as a moisture adsorbing means. One end of the moisture adsorbent 11 is located at a position where one end can be immersed in the oil accumulated in the oil tank 3, such as a lower portion (lower side portion) and a bottom portion of the oil tank 3, and the other end is a compressed air outlet from which compressed air is sent out. At the position just before (in the vicinity of the compressed air outlet), it is a series. Further, a heater 12 is provided as a heating means for heating the end of the moisture adsorbent 11 in the vicinity of the air outlet of the oil tank 3 from the outer surface of the oil tank 3. The heater 12 is energized and heated immediately before the compressor main body 2 is operated (driven) and compressed air is generated and until the operation of the compressor main body 2 ends and the internal pressure is released. To do.

以上のような油冷式圧縮機における各機器の動作等について説明する。圧縮機本体２が稼動すると、圧縮機外の空気をエアフィルタ１を介して吸入する。そして圧縮機本体２は圧縮空気を吐出する。このとき、空気に油を供給して（混合させて）圧縮機本体２に吸入させることで、圧縮空気及び圧縮機本体２を冷却する。このため、圧縮空気と共に混入した油が吐出される。   The operation of each device in the oil-cooled compressor as described above will be described. When the compressor main body 2 is operated, air outside the compressor is sucked through the air filter 1. The compressor body 2 discharges compressed air. At this time, the compressed air and the compressor main body 2 are cooled by supplying (mixing) oil to the air and sucking the oil into the compressor main body 2. For this reason, the oil mixed with the compressed air is discharged.

油分離手段４は圧縮空気から混入した油を分離する。分離した油は油タンク３に回収される。そして、回収した油を油タンク３下部から送り出し、オイルフィルタ９、オイルクーラ１０を経て、前述の如く圧縮機本体２に再度供給する。   The oil separation means 4 separates the mixed oil from the compressed air. The separated oil is collected in the oil tank 3. Then, the recovered oil is sent out from the lower part of the oil tank 3 and supplied again to the compressor body 2 through the oil filter 9 and the oil cooler 10 as described above.

ここで、大気中に含まれる水分の一部が、空気圧縮によって凝縮し、油と共に油タンク３に回収される。そこで、油タンク３内面に配された水分吸着材１１のうち、油タンク３の油と共に回収された水分と接する一方の端部では水分を吸着する。また、同時に、ヒータ１２が油タンク３の空気出口付近にあるもう一方の端部では、ヒータ１２による局部的な加熱により、圧縮空気の温度が上昇して飽和水蒸気量が部分的に増加することで、油タンク３内を通過する圧縮空気に吸着した水分を放出（排出、脱着）する。   Here, a part of the moisture contained in the atmosphere is condensed by air compression and collected in the oil tank 3 together with the oil. Therefore, the moisture adsorbing material 11 arranged on the inner surface of the oil tank 3 adsorbs moisture at one end portion in contact with the moisture collected together with the oil in the oil tank 3. At the same time, at the other end where the heater 12 is near the air outlet of the oil tank 3, the temperature of the compressed air rises due to local heating by the heater 12, and the saturated water vapor amount partially increases. Thus, moisture adsorbed on the compressed air passing through the oil tank 3 is released (discharged and desorbed).

水分放出により乾いた部分に吸着された水分が伝っていくことで、回収された水分の吸着と圧縮空気への水分放出が連続的に発生し、回収された水分が水分吸着材１１を介して圧縮空気に移行する。このため、油タンク３内から水分を除去することができる。したがって、例えば、油タンク３内に水分がたまっていって油等をあふれさせることを防止することができる。また、油タンク３下部から回収した油と共に送り出される水分量を減らすことができ、潤滑、冷却等をはかるために適切な量の油を圧縮機本体２に供給することができる。   Moisture adsorbed to the dry part by moisture release is transferred, so that the collected moisture is continuously adsorbed and released into the compressed air, and the collected moisture passes through the moisture adsorbent 11. Transition to compressed air. For this reason, moisture can be removed from the oil tank 3. Therefore, for example, it is possible to prevent water from accumulating in the oil tank 3 and overflowing oil or the like. Further, the amount of water sent out together with the oil recovered from the lower part of the oil tank 3 can be reduced, and an appropriate amount of oil can be supplied to the compressor main body 2 for lubrication, cooling and the like.

一方、油タンク３から出た水分吸着材１１が放出した水分を含む圧縮空気を、セパレータエレメント５に通過させて油を濾過する。また、アフタークーラ６が冷却する。さらに、水分離器７は圧縮空気から水分を除去し、エアドライヤ８によりさらに除湿して、外部の装置に送り出す。水分離器７が除去した水分については、例えば排出機構（図示せず）によって装置外に排出する。   On the other hand, the compressed air containing the moisture released from the moisture adsorbing material 11 exiting from the oil tank 3 is passed through the separator element 5 to filter the oil. Moreover, the aftercooler 6 cools. Furthermore, the water separator 7 removes moisture from the compressed air, further dehumidifies it with an air dryer 8, and sends it to an external device. The water removed by the water separator 7 is discharged out of the apparatus by a discharge mechanism (not shown), for example.

以上のように、実施の形態１の油冷式圧縮機においては、油タンク３の内面に、一端側が回収された油等に浸るようにし、他端側が圧縮空気の出口となる部分に位置するように水分吸着材１１を設け、一端側において油に混じった水分を吸着するようにし、他端側においてヒータ１２で加熱することで圧縮空気に放出して油タンク３外に排出するようにしたので、通常の油冷式圧縮機動作中においても、連続的に油タンク３中の水分を分離・排出することができる。また、油中に水分が撹拌されていても、水分吸着材１１が微視的なレベルで水分を選択的に吸着することができるので、水分が油タンク３の底部に沈降する前に除去することができる。このため、油冷式圧縮機における空気回路にバイパス、オリフィス等を追加しなくてもよく、無負荷運転のない油冷式圧縮機でも油の性能劣化を防ぐことが可能となる。   As described above, in the oil-cooled compressor according to the first embodiment, one end side is immersed in the recovered oil or the like on the inner surface of the oil tank 3, and the other end side is located at a portion serving as an outlet for compressed air. In this way, the moisture adsorbing material 11 is provided so that the moisture mixed in the oil is adsorbed on one end side, and the other end side is heated by the heater 12 so as to be released into the compressed air and discharged out of the oil tank 3. Therefore, the water in the oil tank 3 can be continuously separated and discharged even during normal oil-cooled compressor operation. Further, even when moisture is stirred in the oil, the moisture adsorbing material 11 can selectively adsorb moisture at a microscopic level, so that the moisture is removed before settling on the bottom of the oil tank 3. be able to. For this reason, it is not necessary to add a bypass, an orifice or the like to the air circuit in the oil-cooled compressor, and even in an oil-cooled compressor without no-load operation, it is possible to prevent deterioration of the oil performance.

実施の形態２．
図３は、この発明の実施の形態２に係る油冷式圧縮機の油タンク３の断面図である。ここで、油タンク３以外の油冷式圧縮機の構成については、実施の形態１と同じである。 Embodiment 2. FIG.
3 is a cross-sectional view of an oil tank 3 of an oil-cooled compressor according to Embodiment 2 of the present invention. Here, the configuration of the oil-cooled compressor other than the oil tank 3 is the same as that of the first embodiment.

本実施の形態では、油タンク３内部に２個以上の一対の水分吸着材１１、ヒータ１２および電動巻上げ機１３を有している。一対の水分吸着材１１については、電動巻上げ機１３により、一方の水分吸着材１１が油タンク３にたまった油に浸漬して水分を吸着している間、他方の水分吸着材１１は油タンク３の空気出口付近において水分放出のためにヒータ１２で加熱される。   In the present embodiment, two or more pairs of moisture adsorbents 11, heaters 12, and electric hoists 13 are provided inside the oil tank 3. As for the pair of moisture adsorbents 11, while one moisture adsorbent 11 is immersed in the oil accumulated in the oil tank 3 and adsorbs moisture by the electric hoist 13, the other moisture adsorbent 11 is in the oil tank. 3 is heated by the heater 12 in order to release moisture in the vicinity of the air outlet 3.

また、本実施の形態のヒータ１２は、油タンク３内部に設けられ、油タンク３の空気出口付近に位置する水分吸着材１１を加熱する。本実施の形態においても、圧縮機本体２が稼動して圧縮空気が発生する直前から、圧縮機本体２の稼動が終了して内圧が開放されるまでの間、ヒータ１２に通電して加熱させるようにする。   In addition, the heater 12 of the present embodiment is provided inside the oil tank 3 and heats the moisture adsorbing material 11 located near the air outlet of the oil tank 3. Also in the present embodiment, the heater 12 is energized and heated immediately before the compressor main body 2 is operated and compressed air is generated and until the operation of the compressor main body 2 is terminated and the internal pressure is released. Like that.

吸着材移動手段となる電動巻上げ機１３は、巻上げ動作が設定されており、ワイヤ等で吊された一対の水分吸着材１１を巻き上げる等して、それぞれの水分吸着材１１を上下方向に移動させ、水分吸着材１１を、油中へ浸漬させる又はヒータ１２によって加熱させることができる。これを釣瓶のように、一対の水分吸着材１１に交互に行わせることができる。   The electric hoisting machine 13 serving as the adsorbent moving means has a hoisting operation, and moves the respective moisture adsorbing materials 11 in the vertical direction by winding up a pair of moisture adsorbing materials 11 suspended by wires or the like. The moisture adsorbing material 11 can be immersed in oil or heated by the heater 12. This can be performed alternately by the pair of moisture adsorbents 11 like a fishing bottle.

以上のように構成した油冷式圧縮機における油タンク３内部における動作について説明する。一対の水分吸着材１１のうち、油タンク３に回収された油中の水分吸着材１１は、油タンク３において回収された水分を吸着する。一方、油タンク３の空気出口の直前に位置するもう一方の水分吸着材１１は、ヒータ１２によって加熱され、空気出口付近の圧縮空気の温度が上昇することによって飽和水蒸気量が部分的に増加して、水分吸着材１１から水分が放出される。   Operation in the oil tank 3 in the oil-cooled compressor configured as described above will be described. Of the pair of moisture adsorbing materials 11, the moisture adsorbing material 11 in the oil collected in the oil tank 3 adsorbs the moisture collected in the oil tank 3. On the other hand, the other moisture adsorbing material 11 located immediately before the air outlet of the oil tank 3 is heated by the heater 12, and the temperature of the compressed air near the air outlet rises, so that the amount of saturated water vapor partially increases. Thus, moisture is released from the moisture adsorbing material 11.

そして、電動巻上げ機１３は、例えば一定時間毎に、浸漬している水分吸着材１１を引き上げてヒータ１２で加熱させると共に、ヒータ１２で加熱している水分吸着材を浸漬させて水分を吸着させる。水分吸着とヒータ１２の加熱による水分放出を、電動巻上げ機１３の動作によって、それぞれの水分吸着材１１が交互に繰り返すことにより、油中の水分が圧縮空気に移行する。油タンク３から出た圧縮空気の処理及び油タンク３下部から送られる油の処理については、実施の形態１で説明したことと同様である。   The electric hoist 13, for example, pulls up the immersed moisture adsorbing material 11 and heats it with the heater 12 at regular intervals, and immerses the moisture adsorbing material heated with the heater 12 to adsorb moisture. . Moisture in the oil is transferred to compressed air by alternately repeating the moisture adsorption and the moisture release by heating the heater 12 by the operation of the electric hoisting machine 13. The processing of the compressed air coming out of the oil tank 3 and the processing of the oil sent from the lower portion of the oil tank 3 are the same as those described in the first embodiment.

以上のように、実施の形態２の油冷式圧縮機によれば、一対の水分吸着材１１において、一方の水分吸着材１１で油と共に回収された水分を吸着しつつ、他方の水分吸着材１１で圧縮空気に放出して油タンク３外に排出するように構成し、電動巻上げ機１３により、交互に行うようにしたので、通常の油冷式圧縮機動作中においても、連続的に油タンク３中の水分を分離・排出することができる。また、油タンク３の内部形状に関らず、水分吸着材１１の形状や体積を自由に設定することができる。そのため、実使用での水分発生条件や油タンクの形状といった個々の状況に対応が可能となる。   As described above, according to the oil-cooled compressor of the second embodiment, in the pair of moisture adsorbing materials 11, while the moisture collected together with the oil is adsorbed in one moisture adsorbing material 11, the other moisture adsorbing material is absorbed. 11 is discharged into the compressed air and discharged out of the oil tank 3, and is alternately performed by the electric hoist 13, so that the oil is continuously generated even during normal oil-cooled compressor operation. The water in the tank 3 can be separated and discharged. In addition, the shape and volume of the moisture adsorbing material 11 can be freely set regardless of the internal shape of the oil tank 3. Therefore, it is possible to cope with individual conditions such as moisture generation conditions in actual use and the shape of the oil tank.

実施の形態３．
上述の実施の形態１および実施の形態２では特に言及しなかったが、水分吸着材１１の材料として、例えばゼオライトを用いるようにしても良い。ゼオライトは、その分子骨格構造を適切に選択することにより、骨格中の細孔において、水分のみを吸着また放出することができる。また、ゼオライトはケイ素を主成分としており、耐油・耐熱性にも優れており、本発明のように、油冷式圧縮機における水分吸着材として好適である。 Embodiment 3 FIG.
Although not particularly mentioned in the above-described first and second embodiments, for example, zeolite may be used as the material of the moisture adsorbing material 11. Zeolite can adsorb or release only moisture in the pores in the framework by appropriately selecting the molecular framework structure. Further, zeolite has silicon as a main component and is excellent in oil resistance and heat resistance, and is suitable as a moisture adsorbing material in an oil-cooled compressor as in the present invention.

実施の形態４．
上述の実施の形態２においては、吸着材移動手段として電動巻上げ機１３を用いて一対の水分吸着材１１を交互に油タンク３底部と圧縮空気出口付近との間を移動させるようにしたが、これに限定するものではない。例えば、ロータ等の循環装置を吸着材移動手段とし、循環装置によって水分吸着材を循環させるようにして、水分の吸着と放出とを繰り返せるようにしてもよい。 Embodiment 4 FIG.
In Embodiment 2 described above, the pair of moisture adsorbents 11 are alternately moved between the bottom of the oil tank 3 and the vicinity of the compressed air outlet using the electric hoist 13 as the adsorbent moving means. However, the present invention is not limited to this. For example, a circulation device such as a rotor may be used as the adsorbent moving means, and the moisture adsorption material may be circulated by the circulation device so that the adsorption and release of moisture can be repeated.

また、吸着材移動手段として、電動巻上げ機１３、循環装置に限らず、例えば、水分吸着材１１が、油中の水分吸着と吸着した水分の油タンク３からの排出をほぼ連続して行わせることができるような機構（装置）で構成してもよい。   Further, the adsorbent moving means is not limited to the electric hoist 13 and the circulation device. For example, the moisture adsorbing material 11 causes moisture adsorption in oil and the adsorption of the adsorbed moisture from the oil tank 3 to be performed almost continuously. You may comprise by the mechanism (apparatus) which can do.
