(57) [Summary] [Purpose] If a dust remover is placed immediately upstream of the sterilizer, even if the drain is separated upstream of the sterilizer, the humidity of the compressed air will rise in the sterilizer and the membrane filter will be used. It may increase the air resistance passing through. [Structure] A drying means such as a heatless dryer 3 is provided immediately upstream of the sterilizer 4. As a result, the compressed air flowing through the discharge pipe 1 to the sterilizer 4 becomes the refrigerating air dryer 2
Since it is dehumidified by and is further dried by the heatless dryer 3, the sterilizer 4 is in a dry state, and the air resistance does not increase. In addition, heating means such as a heater is used as the drying means.

本考案はエアコンプレッサに於ける除菌装置に係わり、更に詳しくはエアコン プレッサによって生成される圧縮空気中に含まれる各種細菌を可及的に除去可能 な装置の改良に関する。 The present invention relates to a sterilization device in an air compressor, and more particularly to improvement of a device capable of removing various bacteria contained in compressed air generated by an air conditioner presser as much as possible.
【０００２】[0002]
常圧の大気やガス中に含まれる微少な汚染物質例えば細菌を捕集する為の技術 として、特開昭54−104082号公報に示されている発明があるが圧縮空気の場合に これのみを適用しただけでは、細菌類を除去する時に、同時にフィルタにドレン 水が付着してしまいそれが却って細菌の生育環境を生成してしまう。 There is an invention disclosed in Japanese Patent Laid-Open No. 54-104082 as a technique for collecting minute pollutants, such as bacteria, contained in atmospheric air or gas, but only this is used in the case of compressed air. If only applied, the drain water will adhere to the filter at the same time when the bacteria are removed, which will rather create a habitat for the bacteria.
【０００３】 そこで本出願人は先に特公平３−３１４８５号公報で示されている発明により 、圧縮空気中の除菌を計る除菌装置を提案した。該発明によればエアコンプレッ サの圧縮空気の吐出配管中に、メンブランフィルタを有する除菌器を配したコン プレッサに於ける除菌装置に於いて、上記吐出配管の除菌器より上流に圧縮空気 中に含まれる水分を除去する冷凍式エアドライヤを配し、その下流に上記冷凍式 エアドライヤで除去出来なかった水分を外部へ除去できるドレントラップを有す る除塵用フィルタ器を配設し、その下流に上記除塵用フィルタ器の自動ドレント ラップで除去出来なかった水分を外部へ除去できるドレントラップを有する除菌 器を設け、上記冷凍式エアドライヤ、除菌用フィルタ器のドレントラップ、除菌 器のドレントラップの順序で段々に水分を除去した圧縮空気をメンブランフィル タに通過せしめて除菌するようにした事を特徴とするコンプレッサに於ける除菌 装置とすることにより、メンブランフィルタに圧縮空気の水粒子が付着しないの でメンブランフィルタの目詰りが防止されると共に、メンブランフィルタに水粒 子が付着することが可及的に防止されるから、そこに菌の増殖環境が形成される ことが防がれる。故に除菌効果がよい。Therefore, the present applicant has proposed a sterilization device for measuring sterilization in compressed air according to the invention disclosed in Japanese Patent Publication No. 3-31485. According to the invention, in a sterilization device in a compressor in which a sterilizer having a membrane filter is arranged in a discharge pipe of compressed air of an air conditioner, the compressor is compressed upstream of the sterilizer in the discharge pipe. A freezing air dryer that removes the water contained in the air is placed, and a dust removal filter device that has a drain trap that can remove the water that could not be removed by the above freezing air dryer to the outside is placed downstream of that. A sterilizer with a drain trap that can remove the water that could not be removed by the automatic drain wrap of the dust filter is installed downstream, and the freezing air dryer, the drain trap of the sterilization filter, and the sterilizer are installed. A feature of the present invention is that the compressed air from which water has been gradually removed in the order of a drain trap is passed through a membrane filter to remove bacteria. By using the sterilization device at the server, the water particles of the compressed air do not adhere to the membrane filter, so clogging of the membrane filter can be prevented and water particles can adhere to the membrane filter. Therefore, it is possible to prevent the growth environment of bacteria from being formed there. Therefore, the disinfection effect is good.
【０００４】[0004]
本出願人の提案した除菌装置では圧縮空気の上流側より下流側に向ってドライ ヤ、除菌用フィルタ器、除菌器の順に配列されている。然して、除塵用フィルタ 器及び除菌器は自動ドレントラップを備えている。ドライヤで除湿された圧縮空 気は除塵用フィルタ器を経由するため温度が下り相対湿度が上昇する。そのため 、除塵用フィルタで除湿しても、その除湿は温度降下によるものなので除菌器へ は相対湿度の高い圧縮空気が流れる。従って、除菌器内へは高湿度圧縮空気が入 るのでメンブランフィルタは湿り、空気抵抗は増し圧縮空気圧、流量の低下を来 し、末端必要圧力、流量が得られないという場合がある。又、自動ドレントラッ プがあるため、ドレンの排水処理が必要となる。又、必ずドライヤ、除菌用フィ ルタ器、除菌器の順に配列しなければならないので圧縮空気吐出配管へ介装する 機器が固定的であり、融通性がない。更に又、エアドライヤ及び除塵用フィルタ 器による脱水だけでは尚圧縮空気中に水分が残るため、除菌器では水分が分離さ れるので除菌器のドレン排水処理が必須不可欠となっている。 In the disinfection device proposed by the applicant, a dryer, a disinfection filter device, and a disinfection device are arranged in this order from the upstream side to the downstream side of the compressed air. However, the dust filter and sterilizer are equipped with an automatic drain trap. Since the compressed air dehumidified by the dryer passes through the dust filter, the temperature drops and the relative humidity rises. Therefore, even if it is dehumidified by the dust filter, the dehumidification is due to the temperature drop, so compressed air with high relative humidity flows to the sterilizer. Therefore, since high-humidity compressed air enters the sterilizer, the membrane filter becomes moist, the air resistance increases, the compressed air pressure and flow rate decrease, and the required terminal pressure and flow rate may not be obtained. Also, since there is an automatic drain trap, drainage wastewater treatment is required. Also, since the dryer, the sterilization filter device, and the sterilization device must be arranged in this order, the equipment installed in the compressed air discharge pipe is fixed and inflexible. Furthermore, since water remains in the compressed air only by dehydration with an air dryer and a filter for dust removal, the water is separated in the sterilizer, so drain wastewater treatment of the sterilizer is indispensable.
【０００５】 本発明は圧縮空気吐出配管の配列に応じて除菌可能であり、除菌性能が変化少 なく、圧縮空気に対する抵抗の変化が少なく、必ずしもドレン処理を要しないエ アコンプレッサに於ける除菌装置を提供することを目的としている。The present invention is an air compressor that can sterilize in accordance with the arrangement of the compressed air discharge pipe, has a small sterilization performance, a small change in resistance to compressed air, and does not necessarily require drain treatment. It is intended to provide a disinfection device.

【００１５】 上記メンブランフィルタ２１としては、通常、０．１ミクロンメータ（μｍ） 〜５ミクロンメータ（μｍ）程度のものがあるが、一般細菌類、カビ、酵母など の真菌類の除菌を可能にする為、０．１（μｍ）〜０．４（μｍ）程度のものを 用いる。且つこのメンブランフィルタの材質は再生セルローズ製、ニトロセルロ ーズ等が考慮される。As the membrane filter 21, there is usually about 0.1 micrometer (μm) to 5 micrometer (μm), but it is possible to eradicate fungi such as general bacteria, mold and yeast. For this reason, a material having a thickness of about 0.1 (μm) to 0.4 (μm) is used. Moreover, as the material of the membrane filter, regenerated cellulose, nitrocellulose or the like is considered.
【００１６】 このような構成に基づくと、エアコンプレッサによって生成された圧縮空気が 吐出配管１中を通る時に、先ず冷凍式エアドライヤ２によって除湿される。即ち 、冷凍式エアドライヤ２に於いて、予冷、本冷されて冷却されることにより、圧 縮空気中の水蒸気が凝縮されて。ドレン水となって付加せるドレントラップによ り大気へ自動的に排出される。According to such a configuration, when the compressed air generated by the air compressor passes through the discharge pipe 1, it is first dehumidified by the refrigeration air dryer 2. That is, in the refrigeration type air dryer 2, water vapor in the compressed air is condensed by pre-cooling, main cooling and cooling. It is automatically discharged to the atmosphere by a drain trap that can be added as drain water.

Therefore, the water in the compressed air is sorbed by passing through the silica gel 11 from the upper dispersion chamber 8 of the adsorption cylinder 7A through the port 6A. At the same time, dust is removed while passing through the silica gel of the granules, and the dust comes out to the lower dispersion chamber 9, goes through the check valve 12, and proceeds to the sterilizer 4. At the same time, the compressed air discharged from the check valve 12 on the side of the adsorption cylinder 7B is communicated to the atmosphere through the four-way switching valve 6 on the adsorption cylinder 7B, so the check valve 12 on the side of the adsorption cylinder 7B is closed and dried. A part of the compressed air that has passed through the orifice 13 on the adsorption cylinder 7B side enters the lower dispersion chamber 9 of the adsorption cylinder 7B, and is discharged into the atmosphere through the silica gel 11, the upper dispersion chamber 8, and the four-way switching valve 6. .. The silica gel 11 on the side of the adsorption cylinder 7B contains the moisture adsorbed from the moist compressed air by the switching of the four-way switching valve 6, but is dried and regenerated by the dry air. When the four-way switching valve 6 is switched, the port 6A is closed and the port 6B is opened. Therefore, the above actions are switched by the adsorption cylinders 7A and 7B, the compressed air is dehumidified by the adsorption cylinder 7B, and the silica gel 11 in the adsorption cylinder 7A is dried. Is done.
【００１８】 ヒートレスエアドライヤ３を出たほぼ完全乾燥状態の圧縮空気は次に除菌器４ の流入口２２よりメンブランフィルタ２１に直接当ることなく、その外側のハウ ジング１６内に流入し、そこからメンブランフィルタ２１内を通過する。The compressed air in the almost completely dried state that has exited the heatless air dryer 3 then flows into the housing 16 on the outside thereof from the inflow port 22 of the sterilizer 4 without directly hitting the membrane filter 21. To pass through the membrane filter 21.
【００１９】 圧縮空気は充分高い乾燥度となっているのでメンブランフィルタ２１が圧縮空 気中に含まれるドレン水粒子によって目詰まりしたりすることもなく、且つメン ブランフィルタ２１にドレン水粒子が付着して細菌増殖環境がかえって生ずるよ うなこともない。上記の工程迄に於いては段々と除湿され、且つ除塵は可能にさ れるが、菌類は通してしまうので、除菌は不可能であったが、メンブランフィル タ２１を通過する時に除かれ、メンブランフィルタ２１を孔径０．１μｍ〜０． ４μｍ程度に設定してあるので、ここを通る時に一般細菌類、真菌類は表面で機 械的に捕集される。Since the compressed air has a sufficiently high dryness, the membrane filter 21 will not be clogged with the drain water particles contained in the compressed air, and the drain water particles will adhere to the membrane filter 21. Then, the bacterial growth environment does not occur. Up to the above steps, it was gradually dehumidified and dust could be removed, but bacteria could pass through, so it was impossible to remove bacteria, but it was removed when passing through the membrane filter 21, The membrane filter 21 has a pore size of 0.1 μm to 0. Since it is set to about 4 μm, general bacteria and fungi are mechanically collected on the surface when passing through here.
【００２０】 そして、メンブランフィルタ２１の内側から流出口２３を経て使用場所へ圧縮 空気が供給される。Then, compressed air is supplied from the inside of the membrane filter 21 to the place of use through the outlet 23.
【００２１】 以上詳述した如く、この実施例によれば、最上流側に於いて先ず冷凍式エアド ライヤによって圧縮空気を除湿し、圧縮空気中のドレン水がそこで分離される。 そして次のヒートレスエアドライヤで更に圧縮空気中の水分が除菌器４を通過し 得る支障のない程度除かれると共に除塵される。従って、除菌器には充分乾燥し た空気が送り込まれ、除菌器において圧縮空気中の水分が凝縮するということが なく、メンブランフィルタの目詰まりは生じない。As described above in detail, according to this embodiment, the compressed air is first dehumidified on the most upstream side by the refrigeration type air dryer, and the drain water in the compressed air is separated there. Then, in the next heatless air dryer, the water in the compressed air is further removed to the extent that it does not hinder the passage of the sterilizer 4 and dust is removed. Therefore, sufficiently dry air is sent to the sterilizer, water in the compressed air does not condense in the sterilizer, and clogging of the membrane filter does not occur.
【００２２】 「実施例２」 食品製造工業等では除菌は必須不可欠であっても必ずしも乾燥空気が必要でな く、場合によっては加湿して除菌された圧縮空気を用いねばならない場合も生ず る。一方、除菌器では可能な限り、乾燥した圧縮空気を通過させるのが望ましい 。本実施例はこのような目的に対して用い得るものの１つである。[Example 2] Even if sterilization is indispensable in the food manufacturing industry and the like, dry air is not always required, and in some cases, humidified and sterilized compressed air must be used. Slip. On the other hand, it is desirable to pass dry compressed air through the sterilizer as much as possible. This embodiment is one that can be used for such a purpose.
【００２３】 図２において圧縮空気吐出配管１には冷凍式エアドライヤ２、空気加熱手段３ ０、除菌器４の順で上流より下流に向って介装されている。除菌器４は前実施例 と同じであるのでその説明は省略する。In FIG. 2, a compressed air discharge pipe 1 is provided with a refrigerating air dryer 2, an air heating means 30 and a sterilizer 4 in this order from upstream to downstream. Since the sterilizer 4 is the same as that of the previous embodiment, its description is omitted.
【００２４】 上記に於ける空気加熱手段３０は一次側を温水又は図示のようにバーナとファ ンよりなるファンヒータ２９で生成した加熱空気２８を通じ二次側に冷凍式エア ドライヤ２と除菌器４間の圧縮空気吐出配管１とした熱交換器３０Ａとする。こ うすると冷凍式エアドライヤ２を出た乾燥空気の湿度は低下するので湿度の低下 した乾燥空気が除菌器４を通過するので除菌器４内は常に乾燥状態が保たれ、メ ンブランフィルタ２１の目詰まりが防止される。除菌器４を出た圧縮空気は放熱 により、湿度は上昇するが目的に照らして問題がない。In the air heating means 30 in the above, the primary side is hot water or the heated air 28 generated by a fan heater 29 composed of a burner and a fan as shown in the drawing is used to pass the refrigerating air dryer 2 and the sterilizer to the secondary side. 4 and the compressed air discharge pipe 1 between the heat exchangers 30A. When this happens, the humidity of the dry air discharged from the refrigeration type air dryer 2 decreases, and the dry air with the decreased humidity passes through the sterilizer 4, so the inside of the sterilizer 4 is always kept dry, and the membrane filter is used. The clogging of 21 is prevented. The compressed air discharged from the sterilizer 4 radiates heat to raise the humidity, but there is no problem for the purpose.
【００２５】 「実施例３」 図３に実施例３を示す。実施例２において空気の加熱手段３０がヒータの場合 であり、本例では圧縮空気吐出配管１を拡径して内部に電気抵抗発熱体３１を配 設し、該電気抵抗発熱体３１で圧縮空気を加熱し、温度上昇し、湿度の低下した 圧縮空気を除菌器４へ送る。本例の場合は空気加熱手段３０をシーズヒータとし 、除菌器４のハウジング１６内壁に沿って設けると装置がコンパクトとなる効果 がある。Third Embodiment FIG. 3 shows a third embodiment. This is a case where the air heating means 30 is a heater in the second embodiment, and in this example, the compressed air discharge pipe 1 is expanded in diameter and an electric resistance heating element 31 is arranged inside the compressed air discharge piping 31. The compressed air whose temperature has risen and whose humidity has decreased is sent to the sterilizer 4. In the case of this example, when the air heating means 30 is a sheath heater and is provided along the inner wall of the housing 16 of the sterilizer 4, there is an effect that the apparatus becomes compact.
【００２６】 「実施例４」 図４に実施例４を示す。圧縮空気吐出配管１に冷凍式エアドライヤ２、空気加 熱手段３０、除菌器４が介装されている点は実施例２，３と同様である。冷凍式 エアドライヤ２は圧縮機３２で圧縮した冷媒を凝縮器３３に送り、これを減圧弁 ３４で減圧して低温を得、これを熱交換器３５の一次側を通して吐出配管１中の 圧縮空気と熱交換して自らは温度上昇し、圧縮機３２に戻される。熱交換器３５ の二次側には、熱交換器３６の入口３７から図示されないエアコンプレッサで加 圧され、昇温し且つ湿った圧縮空気が送り込まれ、熱交換器３６中を通じて熱交 換器３５へ入り、熱交換器３５の一次側の冷媒に熱を奪われて温度低下した圧縮 空気は熱交換器３６の二次側へ入り、熱交換され温度上昇して熱交換器３６の出 口３８から出て次の加熱手段３０へ進む。本例では該加熱手段３０は冷凍式エア ドライヤ２の凝縮器３３が兼ねており、冷凍式エアドライヤ２の出口３８を出た 圧縮空気は該凝縮器３３の冷却媒体として使用して作用する。凝縮器３３は密閉 圧力容器３９に配した凝縮器３３の配管群を図示矢印イのようにジグザグに圧縮 空気が通過するように隔壁４１を設けてある。この実施例によれば冷凍機で取り 去るべき加熱された冷媒の熱を圧縮空気で取り去るため、加熱手段３０に格別に 加熱源を必要としない。又、加熱量を増加するため、加熱手段を更に付加する場 合も付加する加熱手段は小さくてよい。Fourth Embodiment FIG. 4 shows a fourth embodiment. As in the second and third embodiments, the compressed air discharge pipe 1 is provided with the refrigerating air dryer 2, the air heating means 30, and the sterilizer 4. The refrigeration type air dryer 2 sends the refrigerant compressed by the compressor 32 to the condenser 33, decompresses it with the pressure reducing valve 34 to obtain a low temperature, and passes this through the primary side of the heat exchanger 35 to the compressed air in the discharge pipe 1. After exchanging heat, the temperature of the self rises, and the self is returned to the compressor 32. To the secondary side of the heat exchanger 35, pressurized and moist compressed air is fed from an inlet 37 of the heat exchanger 36 by an air compressor (not shown), and is sent through the heat exchanger 36. The compressed air that has entered the heat exchanger 35 and has its temperature lowered due to the heat being taken away by the refrigerant on the primary side of the heat exchanger 35 enters the secondary side of the heat exchanger 36 where it is heat-exchanged and the temperature rises and the outlet of the heat exchanger 36 exits. Exit from 38 and proceed to the next heating means 30. In the present example, the heating means 30 also serves as the condenser 33 of the refrigeration air dryer 2, and the compressed air that has exited the outlet 38 of the refrigeration air dryer 2 is used as a cooling medium for the condenser 33 to act. The condenser 33 is provided with a partition wall 41 so that compressed air can pass through the piping group of the condenser 33 arranged in the closed pressure vessel 39 in a zigzag manner as shown by arrow A in the figure. According to this embodiment, the heat of the heated refrigerant to be removed by the refrigerator is removed by the compressed air, so that the heating means 30 does not require a special heat source. Further, since the heating amount is increased, when the heating means is further added, the heating means to be added may be small.

In this embodiment, the compressed air which is pressurized by an air compressor, has a high temperature, and has a high humidity is heated by a heating means 30 to reduce a relative humidity, so that the sterilizer 4 does not condense at a high temperature. As air, bacteria are removed, and then water in the compressed air is removed by a refrigerating air dryer 2. A compressed air discharge pipe 1 is installed in order from an air conditioner compressor (not shown), a bacteria remover (not shown), a heating means 30, and a remover. A sterilizer 4 and a cold-freezing air dryer 2 are installed. In this embodiment, since the compressed air at a temperature of 30 ° C., for example, heated by an air compressor is heated, a heater such as an electric resistance heating element or a combustion type heating means is suitable as the heating means 30. It can also be sterilized by heating it to a high temperature.
【００２８】[0028]
本考案はメンブランフィルタ式の除菌器のすぐ上流側に圧縮空気の乾燥手段を 設けたため、除菌器がしめることがないので除菌器の除菌能力が保持され、圧縮 空気に対する抵抗が増加して供給空気量が減少し、末端必要圧力が低下するおそ れがない効果がある。 In the present invention, a means for drying compressed air is provided immediately upstream of the membrane filter type sterilizer, so that the sterilizer does not squeeze, so the sterilizing ability of the sterilizer is maintained and the resistance to compressed air increases. As a result, the amount of supplied air is reduced, and the required pressure at the end is not reduced.
【００２９】 乾燥手段としてヒートレスエアドライヤを用いると末端に必要な圧縮空気の温 度が低く、又湿度も低い乾燥空気が得られる。When a heatless air dryer is used as the drying means, the temperature of the compressed air required at the end is low and the dry air with low humidity can be obtained.
【００３０】 乾燥手段として加熱手段を用いると他の空圧機器との配置がどのような場合で も実施可能であり、装置設計の融通性がある。When the heating means is used as the drying means, the arrangement with other pneumatic equipment can be carried out in any case, and the apparatus design is flexible.
【００３１】 乾燥手段と除菌器を一体的に構成すると装置はまとめられ、設置場所が小さく てすむ。If the drying means and the sterilizer are integrally configured, the device can be integrated and the installation place can be small.
