Abstract

PURPOSE:To perform dehumidification of compressed air at high efficiency with a small and light weight device without requiring exchange of parts nor particular electric power by separating compressed air to hot and cold air by adiatic expansion, dehumidifying the compressed air by the cold air, then mixing the hot air to elevate the temp. of the cold air. CONSTITUTION:Compressed air from a compressor at high temp. and high humidity is introduced into a device from an inlet 1 of the device 20, cooled and dehumidified by contacting with finned tubes 22 which are formed spirally with perforations on the external periphery of an expansion chamber 18; condensed water is discharged from a water discharging hole 3. The compressed air is then passed through a filter 11 removing oil, dust, etc., allowed to cause vortex motion in each groove 24 formed in a flange 23 of a nozzle 19 from an opening 14 of an exhaust air pipe 17, and separated into hot air and cold air by throttle expansion. The cold air is introduced into the expansion chamber 18 from an orifice 26 of the nozzle having a small bore size to transmit the cold to the finned tubes 22. The hot air is sucked by an ejector, etc. from an outlet 4 of the waste heat air through a pipe 5, mixed with the cold air from the expansion chamber 18 and discharged in the form of dry air from the outlet 2.

It is possible to easily and reliably remove humidity and water droplets, which are always an obstacle in various operations, with extremely high efficiency. It relates to a removal device.

できる。Conventionally, as mentioned above, devices for dehumidifying compressed air can be roughly divided into: (1) A pipe or the like through which the compressed air is sent is made into a meandering or spiral shape to pass through the cooler. (2) A method that dehumidifies compressed air by passing it through a fine-mesh moisture absorption filter; (3) A method that dehumidifies compressed air by passing it through a centrifugal separator and causing moisture to adhere to its outer peripheral wall.

。However, in the system of 1.1-(1), the device itself is complicated, and water etc. must be used for the cooler, making it extremely inconvenient to handle. In the (2) type device, the filter itself is easily clogged, and in particular, the compressed air discharged from the compressor contains a lot of oil and dust, so the filter clogging is accelerated. Moreover, if the water in the filter becomes supersaturated, the dehumidifying effect is lost, so the filter itself has to be replaced frequently. Furthermore, the above (3)
The device of this type required a centrifugal separator itself that rotated at high speed, and had drawbacks such as being inconvenient to handle.

特徴とした圧縮空気の除湿装置である。In any case, the basic structure of the present invention is that the basic structure of the present invention is not particularly concerned with the construction means adopted for each part of the mechanism, but is capable of handling high temperature, high humidity, and oil content sent from an appropriate compressor such as a compressor. A mechanical part that adiabatically expands compressed air containing dirt and dust and can separate it into hot and cold air, and dehumidifies the compressed air that flows in from the equipment input [] by the action of the cold air itself separated by the mechanical part. A mechanism section that performs the dehumidification function and drains the water droplets accumulated in the mechanism section to the outside of the device, and a mechanism section that performs the separation function that mixes the separated hot air and cold air while drying. This is a compressed air dehumidifying device characterized by comprising: a mechanical section for discharging air to the outside of the device;

以下、」−述の如く構成した本発明に係る除湿装置の作
用・効果について述べる。Hereinafter, the functions and effects of the dehumidifying device according to the present invention constructed as described above will be described.

ブ体内を通って排気管１７及びノズル１９等を包覆内蔵
した基体１３の部分に達する。First, compressed air, which is hot and humid and contains oil and dust, sent from a suitable compressor such as a compressor, flows into this device from the inlet l of the fuselage body 20, and flows from the inlet to the outer periphery of one expansion chamber 18. While contacting the protruding fin tube body 22, it passes through the fin tube body formed, for example, in a spiral shape, and reaches the part of the base body 13 that encloses and incorporates the exhaust pipe 17, nozzle 19, etc.

そして、当該圧縮空気は、基体１３の下部に設けた網状
の支持体１２と濃密状に配設した鉄屑状等適宜の濾過体
１１を通って基体内に流入する。Then, the compressed air flows into the base body 13 through a mesh-like support 12 provided at the lower part of the base body 13 and an appropriate filter body 11, such as iron scrap, arranged densely.

この時、当該圧縮空気は、」二記濾過体１１にてその油
分や塵埃等が濾過されることになる。At this time, the compressed air is filtered to remove oil, dust, etc. by the filter body 11.

溝２４．２４．２４を通り、口径の異なる排気管１７の
口部２５とノズル１９の口部２６に達することになる。The compressed air that has entered the base body 13 passes through the opening 14 of the exhaust pipe 17.
From there, it passes through valley grooves 24, 24, and 24 of different diameters formed in the flange 23 of the nozzle 19, and reaches the mouth 25 of the exhaust pipe 17 and the mouth 26 of the nozzle 19, which have different diameters.

熱されつつ膨張室１８内に流入することになる。At this time, the compressed air is narrowed and expanded with extremely high efficiency while making a spiral motion in the grooves 24, 24, and 24 formed in the flange 23 of the nozzle 19, so that its heat radiation is highly efficient. At the same time, the heat radiation is separated and sent to the exhaust pipe opening 25, which has a larger diameter than the nozzle opening 26, and this action insulates and separates the compressed air into heat and cold. The cooling air flows into the expansion chamber 18 from the nozzle opening 26, which has a smaller diameter than the opening of the exhaust pipe, while being thermally insulated with extremely high efficiency.

Note that the water droplets are drained from the drain hole portion 3 of the body 20.

Since the exhaust heat air passes through the pipe 5 from the exhaust heat air outlet 4 of 7 and is strongly sucked up by an appropriate ejector etc. provided at the dry air outlet 2, the heat insulation effect and the heat/cold separation effect are even stronger. It will exert its effect.

The cold air sent from the tension chamber 18 is mixed with the cold air and discharged outside the device as dry air.

This is convenient for making appropriate adjustments.
