Yes. Further, the dehumidifier 3 separates the oil and water by the drain water supply pipe 5a in order to supply the water (drain water) removed from the compressed air supplied through the compressed air supply pipe 4a to the oil / water separator 1A. It is connected to the device 1A. In this case, the water (drain water) removed from the compressed air by the dehumidifier 3 is mist generated in the air compressor 2 when the air is compressed by the air compressor 2 (oil atomized in the cylinder of the air compressor 2). ) And oil applied during construction of the compressed air supply pipe 4a in order to avoid rusting in the compressed air supply pipe 4a. In addition, the dehumidifying apparatus in the present invention is not limited to a type of apparatus that condenses and removes moisture in the compressed air by the refrigeration apparatus 41 like the dehumidifying apparatus 3 described above, and may employ a filter type dehumidifying apparatus. it can.

  On the other hand, as shown in FIGS. 2 to 4, the oil / water separator 1 </ b> A is fixed to a side panel (in this example, the back panel X <b> 2: an example of “wall surface” in the present invention) in the housing 42 of the dehumidifier 3. . As shown in FIG. 5, the oil / water separator 1 </ b> A includes a base portion 11, pipe connecting portions 12 a and 12 b, a filter element 13, a housing 14, and a fixture 18 </ b> A, for supplying drain water from the air compressor 2 and the dehumidifier 3. An oil / water separation process is performed on the drain water supplied through the pipe 5a, and drain water from which oil and foreign matter have been removed can be discharged through the drain water discharge pipe 5b. The base portion 11 is formed in a cylindrical shape whose upper end portion is closed, and a filter head 11a for attaching the filter element 13 is disposed therein. In addition, a drain water supply pipe 5a (or connecting pipe 5c) is connected to the peripheral wall of the base part 11 and a drain water discharge is connected to the pipe connecting part 12a (the “first pipe connecting part” in the present invention). The pipe connection part 12b ("the second pipe connection part" in the present invention) to which the pipe 5b for connection (or the connection pipe 5c) is connected is respectively connected. The pipe connecting part 12b passes through the peripheral wall of the base part 11 and is connected to the filter head 11a, whereby the filter element 13 and the drain water discharge pipe 5b (or the connecting pipe 5c are connected via the filter head 11a. ).

  In this case, the drain water supply pipe 5a is an example of the supply side pipe in the present invention. In this compressed air dehumidification system S1A, the pipe connection portion 12a of the oil / water separator 1A on the left side in FIGS. It is connected. Further, the drain water discharge pipe 5b is an example of a discharge side pipe in the present invention. In the compressed air dehumidification system S1A, the drain water discharge pipe 5b is connected to the pipe connection portion 12b of the right oil / water separator 1A in FIGS. Has been. The connecting pipe 5c corresponds to the discharge side pipe in the present invention for the left oil-water separator 1A in FIGS. 3 and 4, and for the right oil-water separator 1A in FIG. Corresponds to side piping. Specifically, the connecting pipe 5c is a pipe that connects the pipe connecting part 12b of the left oil-water separator 1A and the pipe connecting part 12a of the right oil-water separator 1A in FIGS. The drain water discharged by the left oil / water separator 1A is supplied to the right oil / water separator 1A.

  As shown in FIG. 5, the filter element 13 includes a filter element container 13a, and an oil adsorbent 13b and a nonwoven fabric 13c accommodated in the filter element container 13a. The filter element container 13a includes a container body 21 having an inlet 21a opened at the bottom thereof, and a lid 22 having an outlet 22a formed therein and attached to an upper opening of the container body 21. 11 filter heads 11a. In this case, as an example, the container main body 21 is formed by opening an inlet 21a at the bottom thereof after being processed into a container by a blow molding process using polypropylene. The lid 22 is formed by an injection molding process using polyethylene as an example. In this case, a cylindrical body functioning as a connecting pipe with the filter head 11a is erected on the peripheral portion of the outlet 22a on the outer surface of the lid 22, and a sealing O-ring 23 is disposed on the inner surface thereof. Yes.

  In the oil / water separator 1A, the length of the filter element 13 in the direction in which the drain water passes (that is, the distance L3 from the bottom of the container main body 21 to the tip of the cylindrical body of the lid 22) is 315 mm as an example. It has become. In addition, the oil adsorbing material 13b is configured by, for example, a plate-like polypropylene piece or a piece obtained by chopping a fibrous polypropylene. The nonwoven fabric 13c is made of fibrous polypropylene. In this case, in the compressed air dehumidification system S1A (oil-water separator 1A), as described above, the entire filter element 13 (all of the filter element container 13a, the oil adsorbent 13b, and the nonwoven fabric 13c) is formed of a resin material. Therefore, the weight is very light with 10 kg or less. Therefore, a heavy machine such as a forklift is not required during replacement work described later.

  The housing 14 is formed in a bottomed cylindrical body, and is attached to the base portion 11 so that the filter element 13 is accommodated therein (so as to cover the filter element 13). Further, the bottom wall of the housing 14 is formed in a dome shape that protrudes outward as it approaches the central portion, and a drain port 15 is disposed at the most protruding portion (central portion). In this case, the base portion 11 and the housing 14 configured as described above are, for example, an opening side end portion (lower end portion) in the peripheral wall of the base portion 11 and an opening side end portion (upper end portion) in the peripheral wall of the housing 14. Are inserted and connected to each other. An O-ring 16 for sealing is disposed on each overlapping portion of the peripheral wall of the base portion 11 and the peripheral wall of the housing 14. The base portion 11 and the housing 14 are integrated so that the connecting portion is fastened by a metal band 17. In this case, in this oil / water separator 1A, the distance L4 from the upper end of the housing 14 to the lower end of the drain port 15 is 400 mm as an example.

  On the other hand, the fixture 18A is a fixture for attaching the oil / water separator 1A to the wall surface (in this example, the outer surface of the back panel X2 in the housing 42 of the dehumidifier 3), and this compressed air dehumidification system S1A. In the two oil-water separators 1A, the two pipe connections 12a and the pipe connection part 12b of the other oil-water separator 1A are held by the fixtures 18A, respectively. The structure fixed so that it may be supported by fishing support (hanging down and supporting) is employ | adopted. As shown in FIG. 6, the fixture 18A includes a U-shaped stay 31 that holds the pipe connection portion 12a (or the pipe connection portion 12b) in a tightened state, an L-shaped bracket 32a, and a bracket 32a. And a bolt 33 for fixing the U-shaped stay 31 and a buffer material 34 (for example, an elastic resin or rubber) disposed between the pipe connecting portion 12a (12b) and the U-shaped stay 31. Has been.

  In this case, in the fixture 18A, the U-shaped stay 31, the bolt 33, and the cushioning material 34 are combined to constitute the fixture in the present invention. Further, in the horizontally extending portions 35 of both brackets 32a, when both oil-water separators 1A are used in a stand-alone state by a stand 51 (see FIGS. 9 to 11) as will be described later, both fixtures 18A are attached to the stand 51. An insertion hole 19 through which a bolt 55 (see FIG. 10) for fixing can be inserted is formed. In addition, in this fixing tool 18A, the structure hold | maintained in the state clamp | tightened by the U-shaped stay 31 so that the piping connection part 12a (12b) may be mounted above the horizontal extension part 35 in the bracket 32a is employ | adopted. However, it is also possible to employ a configuration in which the pipe connecting portion 12a (12b) is disposed below the horizontal extending portion 35 in the bracket 32a and supported by the U-shaped stay 31 or the like.

  Next, a method of using the compressed air dehumidification system S1A (oil / water separator 1A) will be described with reference to the drawings.

  In this compressed air dehumidification system S1A, as described above, the configuration in which both the oil-water separator 1A is fixed to the outer surface of the rear panel X2 in the housing 42 of the dehumidifier 3 so as to be supported by the two fixtures 18A. It has been adopted. Therefore, it is possible to secure a sufficient space below both the oil-water separators 1A by fixing both the oil-water separators 1A to the upper part of the casing 42. In this case, as described above, the distance L3 from the lower end to the upper end of the filter element 13 of the oil / water separator 1A is 315 mm. Moreover, 1 A of both oil-water separators are the distance L4 from the upper end part of the housing 14 to the lower end part of the drain port 15 being 400 mm. Therefore, the distance L5 (FIGS. 2 and 3) in the height direction of the space secured below both oil-water separators 1A is equal to or greater than 400 mm (that is, the upper end of the housing 14 in the oil-water separator 1A). By fixing both oil-water separators 1A to the casing 42 so that the distance L1 (see FIGS. 2 and 3) between the floor surface X1 and the floor surface X1 is not less than 715 mm, which is the sum of the distance L3 and the distance L4, While maintaining the state where the filter element 13 is attached to the base portion 11, the housing 14 can be moved downward to be easily detached from the base portion 11.

  In this case, when removing the housing 14 from the base portion 11, in order to secure a work space so that the band 17 can be sufficiently expanded, a wall surface (in this example, a casing) It is preferable that a distance L2 (see FIGS. 2 and 4) between the base portion 11 and the housing 14 is 30 mm or more. As a result, the band 17 can be sufficiently expanded and the housing 14 can be easily detached from the base portion 11. Thereby, the filter element 13 attached to the base part 11 can be easily removed. At this time, since a sufficiently wide space is secured below the both oil-water separators 1A, a container (not shown) for storing drain water dripping from the filter element 13 is provided in the oil-water separator 1A. The filter element 13 can be replaced in a state where it is installed below.

  In addition, when removing the filter element 13 from the base part 11 after removing the housing 14 from the base part 11, as mentioned above, the distance L5 of the height direction in the space under both oil-water separators 1A needs to be 400 mm or more. However, for example, in a state where the connection of the housing 14 to the base portion 11 is released and the housing 14 is slightly moved downward with respect to the base portion 11, the filter element 13 is dropped into the housing 14. In this way, the filter element 13 can be removed from the base portion 11. In the case of adopting such a removal method, it is only necessary to move the housing 14 downward until the upper end of the filter element 13 (for example, the outer peripheral portion of the lid 22) can be touched. If the distance L5 in the height direction in the space below the apparatus 1A is about 100 mm, the filter element 13 can be removed from the base portion 11.

  In this case, as described above, since the filter element 13 is configured to be very lightweight, when replacing the filter element 13 of the oil-water separator 1A, not only a heavy machine such as a forklift is required, but also one person Even if a worker works, the work can be completed in 30 minutes or less. The filter element 13 employed in the compressed air dehumidification system S1A (oil / water separator 1A) is smaller than the filter element of the oil / water separator in the conventional air dryer disclosed by the applicant. Therefore, the exchange frequency is somewhat higher than that of the conventional apparatus. However, as described above, since the replacement can be easily performed in a very short time, that is, the maintainability is improved, the human load and the time load during the replacement work are sufficiently reduced. Furthermore, since the replacement work is easy as described above, the filter element 13 can be periodically replaced in a short period before the filtering ability of the filter element 13 is greatly reduced. Moreover, in this compressed air dehumidification system S1A, as described above, both the oil-water separators 1A are fixed in the vicinity of the heat exhaust holes 42a in the casing 42 of the dehumidifier 3. For this reason, when the compressed air dehumidifying system S1A is in operation, the exhaust heat from the refrigeration apparatus 41 (the compressor 41a and the condenser 41d) in the casing 42 passes through the exhaust heat hole 42a and is transferred to the oil-water separator 1A. Will be. Therefore, both the oil-water separator 1 </ b> A is warmed by the exhaust heat from the dehumidifier 3 even in winter when drain water is frozen.

  Thus, in the oil / water separator 1A and the compressed air dehumidification system S1A, the pipe connection portion 12a for connecting the drain water supply pipe 5a (or the connecting pipe 5c) for supplying the drain water to be treated, The pipe connection part 12b for connecting the drain water discharge pipe 5b (or the connection pipe 5c) for discharging the drain water that has been treated is connected to the pipe connection parts 12a and 12b, and the filter element 13 is connected to the pipe connection part 12b. The oil / water separator 1A is supported on at least one of the base parts 11 that are detachably mounted (in this example, two of the pipe connection parts 12a and 12b), and either the wall surface or the ceiling surface (in this example) Then, the fixing tool 18A for fixing to the back panel X2 of the housing | casing 42 in the dehumidification apparatus 3: An example of a wall surface is attached.

  Therefore, according to the oil / water separator 1A and the compressed air dehumidification system S1A, unlike the conventional air dryer, the operation of removing the housing 42 when replacing the filter element 13 or the main body of the separator (in this example, the base 11 or the like) As a result, the replacement work can be easily performed in a short time. Further, according to the oil / water separator 1A and the compressed air dehumidification system S1A, the oil / water separator 1A is mounted by attaching the oil / water separator 1A to the wall surface (in this example, the outer surface of the rear panel X2 of the housing 42). A sufficiently large space can be ensured below the bottom. Therefore, since the housing 14 and the filter element 13 can be easily detached from the base portion 11 simply by moving the housing 14 and the filter element 13 downward with respect to the base portion 11 during replacement work, according to the oil / water separator 1A and the compressed air dehumidifying system S1A Even when the weight of the filter element 13 is increased by adsorbing oil or the like, it can be easily replaced. Moreover, the situation where valuable installation space is occupied by both oil-water separators 1A can be avoided, and the space secured under both oil-water separators 1A can be effectively utilized.

  Further, according to the oil / water separator 1A and the compressed air dehumidifying system S1A, at least the pipe connecting portions 12a and 12b and the base portion 11 with respect to the L-shaped bracket 32a and the horizontally extending portion 35 of the bracket 32a. By configuring the fixing tool 18A by including a U-shaped stay 31, a bolt 33, and a cushioning material 34 (an attachment in the present invention) for attaching one (in this example, two of the pipe connection portions 12a and 12b), Not only can the oil / water separator 1A be easily fixed to the casing 42 (side panel, etc.) of the dehumidifier 3, but the manufacturing cost can be sufficiently reduced by adopting the fixture 18A having a simple configuration. Can do.

  Further, according to the oil / water separator 1A and the compressed air dehumidification system S1A, the oil / water separator 1A is fixed to the outer surface of the side panel (in this example, the rear panel X2) in the housing 42 of the dehumidifier 3 by the fixture 18A. By doing so, the installation space under both oil-water separators 1A (namely, the circumference of the installation place of dehumidifier 3) can be used effectively.

  Further, according to the oil / water separator 1A and the compressed air dehumidifying system S1A, the oil / water separator 1A is fixed in the vicinity of the heat exhaust hole 42a on the outer surface of the side panel (in this example, the back panel X2), thereby Since both the oil / water separator 1A can be warmed by the exhaust heat from the heat holes 42a, it is possible to avoid the situation where the drain water freezes in the oil / water separator 1A when using the compressed air dehumidification system S1A in winter. it can.

  Furthermore, according to this compressed air dehumidification system S1A, by providing two oil-water separators 1A, oil and foreign matter that could not be completely removed by one oil-water separator 1A are reliably removed by the other oil-water separator 1A. can do.

Na us, above Symbol compressed air dehumidification system S1A of adopts the structure of fixing the both oil-water separating device 1A by a fixture 18A on the outer surface of the rear panel X2 in the housing 42 of the dehumidifier 3, for example, it is possible to use a construction for fixing the both oil-water separating device 1A by a fixture 18A on the wall of the building is installed an air compressor 2 and the dehumidifier 3. Even in such a configuration, unlike the conventional air dryer, the operation of removing the housing 42 when replacing the filter element 13 can be made unnecessary as in the case of the oil / water separator 1A and the compressed air dehumidifying system S1A. As a result, the replacement work can be easily performed in a short time. Moreover, by attaching both oil-water separators 1A to the wall surface, a sufficiently wide space can be secured below both oil-water separators 1A. Therefore, since the housing 14 and the filter element 13 can be easily removed from the base part 11 by simply moving the housing 14 and the filter element 13 downward with respect to the base part 11, the weight of the filter element 13 is increased by adsorbing oil or the like. It can be easily replaced even in the state. Moreover, the situation where valuable installation space is occupied by both oil-water separators 1A can be avoided, and the space secured under both oil-water separators 1A can be effectively utilized.

Also, the compressed air dehumidifying systems S1 B shown in FIG. 7, the two oil-water separation apparatus 1B (as one example, a ceiling of a building installed compressed air dehumidifying systems S1B) ceiling surface X3 by two fasteners 18B lowered fishing from In this way, a configuration for fixing is adopted. In addition, about the component which has the same function as compressed air dehumidification system S1A and oil-water separator 1A which were mentioned above in this compressed air dehumidification system S1B and oil-water separator 1B, the same code | symbol is attached | subjected and the overlapping description is abbreviate | omitted. . In this compressed air dehumidification system S1B (oil-water separator 1B), 2 for fixing both oil-water separators 1B to the ceiling surface X3 instead of the fixture 18A in the compressed air dehumidifier system S1A (oil-water separator 1A). One fixture 18B is provided.

  In this case, the fixing tool 18B holds the two locations of the pipe connection portion 12a of the two oil / water separators 1B and the pipe connection portion 12b of the other oil / water separator 1B on the ceiling surface X3. The fixed structure is adopted. Specifically, as shown in FIG. 8, the fixture 18 </ b> B has a U-shaped stay 31 for holding the pipe connection portion 12 a (or the pipe connection portion 12 b) in a tightened state, and a U-shape in a side view. A bracket 32b, a bolt 33 for fixing the U-shaped stay 31 to the bracket 32b, and a buffer material 34 (for example, an elastic resin) disposed between the pipe connecting portion 12a (12b) and the U-shaped stay 31 Or rubber). In addition, in this fixture 18B, although the piping connection part 12a (12b) is arrange | positioned under the horizontal extension part 35 of the lower side in the bracket 32b, the structure supported by the U-shaped stay 31 etc. is employ | adopted, A configuration in which the pipe connecting portion 12a (12b) is placed above the lower horizontal extending portion 35 in the bracket 32b and is held in a state of being tightened by the U-shaped stay 31 may be employed.

  In this compressed air dehumidification system S1B, as described above, a configuration is adopted in which both oil-water separators 1B are fixed to the ceiling surface X3 so as to be supported by the two fixtures 18B. For this reason, it is possible to secure a sufficient space below both the oil-water separators 1B in the same manner as the compressed air dehumidification system S1A (oil-water separator 1A). Therefore, as shown in FIG. 7, it is possible to effectively utilize the installation space by installing, for example, the dehumidifying device 3 below the oil-water separator 1B. In this case, the distance L5 in the height direction of the space secured below both the oil / water separators 1B (in this example, between the lower end of the oil / water separator 1B and the top surface X1a of the casing 42 of the dehumidifier 3). The two oil-water separators 1B are fixed to the ceiling surface X3 so that the distance is equal to or greater than 400 mm equal to the distance L4 described above, thereby maintaining the filter element 13 attached to the base portion 11 while maintaining the housing 14 Can be easily removed from the base portion 11 by moving it downward.

  In addition, when removing the filter element 13 from the base part 11 after removing the housing 14 from the base part 11, as described above, the distance L5 in the height direction in the space below the both oil-water separators 1B is required to be 400 mm or more. However, for example, in a state where the connection of the housing 14 to the base portion 11 is released and the housing 14 is slightly moved downward with respect to the base portion 11, the filter element 13 is dropped into the housing 14. In this way, the filter element 13 can be removed from the base portion 11. In the case of adopting such a removal method, as described above, it is only necessary to move the housing 14 downward until the upper end portion of the filter element 13 (for example, the outer peripheral portion of the lid body 22) can be touched. Therefore, if the distance L5 in the height direction in the space below both the oil-water separators 1B is about 100 mm, the filter element 13 can be removed from the base portion 11.

Further, in the case where the dehumidifying device 3 or the like is not installed below the both oil-water separators 1B, when the both oil-water separators 1B are fixed at an excessively high position, a step or the like is required for the filter replacement work. The replacement work may be complicated. Therefore, for example, when the average height of the worker is 1.7 m, the distance L1a between the upper end of the housing 14 and the floor surface X1 is within a range of 1.5 m ± 40 cm. By attaching the oil / water separator 1B to the ceiling surface X3 by the fixture 18B, the housing 14 and the filter element 13 can be removed from the base portion 11 without using a step or the like.

  Thus, in the oil / water separator 1B and the compressed air dehumidification system S1B, the pipe connection part 12a for connecting the drain water supply pipe 5a (or the connecting pipe 5c) for supplying the drain water to be treated, The pipe connection part 12b for connecting the drain water discharge pipe 5b (or the connection pipe 5c) for discharging the drain water that has been treated is connected to the pipe connection parts 12a and 12b, and the filter element 13 is connected to the pipe connection part 12b. The oil / water separator 1B is supported on at least one of the base parts 11 that are detachably mounted (in this example, two of the pipe connection parts 12a and 12b), and either the wall surface or the ceiling surface (in this example) Then, the fixture 18B for fixing to the ceiling surface X3) of the building which installed the dehumidification apparatus 3 grade | etc., Is attached.

  Therefore, according to the oil / water separator 1B and the compressed air dehumidification system S1B, unlike the conventional air dryer, when the filter element 13 is replaced, the work such as removing the casing 42 of the dehumidifier 3 or the main body of the separator (in this example, the base As a result of eliminating the need to remove the parts 11 and the like, the replacement work can be easily performed in a short time. Further, according to the oil / water separator 1B and the compressed air dehumidification system S1B, both the oil / water separators 1B are attached to the ceiling surface X3 (in this example, the ceiling surface X3 of the building where the dehumidifier 3 and the like are installed). A sufficiently wide space can be secured below the oil-water separator 1B. Therefore, since the housing 14 and the filter element 13 can be easily detached from the base portion 11 by simply moving the housing 14 and the filter element 13 downward with respect to the base portion 11 during the replacement work, according to the oil / water separator 1B and the compressed air dehumidifying system S1B. Even when the weight of the filter element 13 is increased by adsorbing oil or the like, it can be easily replaced. Moreover, the situation where a valuable installation space is occupied by the both oil-water separators 1B can be avoided, and the space secured below the both oil-water separators 1B can be effectively utilized.

Further, according to the oil / water separator 1B and the compressed air dehumidifying system S1B, at least the pipe connecting portions 12a and 12b and the base portion 11 with respect to the bracket 32b having a U-shape in side view and the horizontal extending portion 35 in the bracket 32b. one (in this example, the pipe connecting portion 12a, 2 two 12b) U-shaped stay 31 for mounting a by constructing the fastener 18B and a bolt 33 and buffer material 3 4, installed dehumidifier 3, etc. The oil / water separator 1B can be easily fixed to the ceiling surface X3 or the like of the building, and the manufacturing cost can be sufficiently reduced by adopting the fixture 18B having a simple configuration.

On the other hand , the usage form of the oil / water separator is used in a state in which it is fixed to the rear panel X2 of the housing 42 of the dehumidifier 3 or the wall surface of the building via the fixture 18A, and to the building via the fixture 18B. It is not limited to the form used in the state fixed to the ceiling surface X3 or the like. Specifically, using the stand 51 shown in FIG. 9, as shown in FIGS. 10 and 11, it is possible to employ a form in which the oil / water separator 1 </ b> A is used independently on the floor surface X <b> 1. In this case, as shown in FIG. 9, the stand 51 includes a pair of beams 52a, a pair of beams 52b, a single beam 52c, a pair of posts 53a, and a pair of posts 53b, and fixes the above-described fixture 18A. It is configured to be possible. In this case, in the stand 51, the post 53a, the beam 52a, and the post 53b are integrally formed so that the lower ends of the posts 53a and 53b are connected by the beam 52a. Further, at the upper end of each post 53a, 53b, a bolt 55 (see FIG. 6) inserted through the insertion hole 19 (see FIG. 6) formed in the fixture 18A when fixing both fixtures 18A to the stand 51. An insertion hole 54 is formed through which an insertion hole (see FIG. 10) is inserted.

This stand 51 connects the lower ends of both posts 53a with one of both beams 52b, connects the lower ends of both posts 53b with the other of both beams 52b, and is located above the center in the vertical direction of both posts 53b. It is assembled so that the beam 52c is stretched over. In this stand 51, constituting the "legs" to Tsu each beam 52a, 52b is coupled with. Also, in the stand 51, two posts 53a constitutes a "first struts", both post 53b constitutes the "second struts." Further, in the stand 51, each post 53a, the upper end portion of 53b (portion insertion hole 54 is formed) constituting the "fixed portion". In the following description, components other than the stand 51 (components having the same functions as the components of the oil / water separator 1A and the fixture 18A in the compressed air dehumidification system S1A) are denoted by the same reference numerals. Therefore, duplicate explanations are omitted.

When using the stand 51 in a state where the oil-water separator 1A is self-supporting, first, the fixture 18A is fixed to the stand 51. Specifically, as shown in FIG. 10, the horizontal extension 35 in the fixture 18A is spanned between both upper ends of the posts 53a and 53b connected via the beam 52a. Both oil-water separators 1A are arranged. Next, a nut (not shown) is tightened with bolts 55 inserted into the insertion holes 19 of the horizontal extension 35 in the fixture 18A and the insertion holes 54 of the posts 53a and 53b in the stand 51, respectively. Thereby, both the fixing tools 18A are fixed to the upper end portions ( fixed portions) of the posts 53a and 53b in the stand 51, and the both oil-water separators 1A are fixed to the stand 51 through the fixing tools 18A. In this state, as shown in FIGS. 10 and 11, the stand 51 is installed so that the beams 52a and 52b (legs ) are in contact with the floor surface X1, so that the oil-water separator 1A is used in a self-supporting state. It becomes possible to do.

  In this way, each beam 52a, 52b and each post 53a, 53b are provided so as to be able to stand on their own, and the fixing portion 18A is removably fixed to the upper end of each post 53a, 53b (this In the example, by providing the stand 51 provided with the insertion hole 54 at the upper end of each post 53a, 53b), the fixing device 18A is fixed to the stand 51 so that the oil / water separator 1A is made self-supporting. Both the oil and water can be used even in an environment where there is no wall surface for fixing the oil / water separator 1A by the fixing tool 18A (for example, when it is not desired to provide a hole for fixing the fixing tool 18A on the wall surface of the building). Separation apparatus 1A can be used.

  Further, the fixture 18A is configured by including a horizontal extending portion 35 to which at least one of the pipe connecting portions 12a and 12b and the base portion 11 (two in this example, the pipe connecting portions 12a and 12b) is attached, Since the stand 51 is configured by including a post 53a that supports one end of the extending portion 35 and a post 53b that supports the other end of the horizontal extending portion 35, the horizontal extending portion 35 of the bracket 32a is configured as a stand. As a result of functioning as a beam for connecting the posts 53a and 53b of the 51, the stand 51 can be easily manufactured to the extent that the beam for connecting the posts 53a and 53b on the upper end side is not necessary. The manufacturing cost can be sufficiently reduced.

Further, the compressed air dehumidification system S1A, S1B (oil-water separation apparatus 1A, 1B) in the pipe connecting portion 12a, 12b in the fastener 18A, but adopts a configuration fitted with 18B, the base over scan portion 11 It is also possible to adopt a configuration in which fixing devices corresponding to the fixing devices 18A and 18B are attached and fixed to the wall surface or the ceiling surface X3. Further, in the compressed air dehumidification systems S1A and S1B, two oil / water separators 1A and 1B are provided, respectively, but the oil and the like are sufficiently removed from the drain water by one oil / water separator 1A and 1B. If it is possible, a compressed air dehumidification system can be configured by including one oil-water separator 1A, 1B.

Also, a post 53a of a pair, but the stand 51 and a post 53b of a pair has been described, eg if, oil-water separation apparatus 1A only a pair of posts 53b in the stand 51, 1B Can be employed (a configuration in which the pair of posts 53a in the stand 51 are not provided: not shown). For example, when the structure (not shown) which supports an oil-water separator with one fixing tool is adopted, one support column provided with a fixed portion capable of fixing the one fixing tool. It includes a section may constitute a "stand" (example of the supporting column portion has one configuration, not shown). Thus, in case of changing the number of struts of the stand also in the same manner as the stand 51 as described above, the oil-water separation apparatus even in an environment where there is no wall or ceiling surface for fixing the oil-water separator by a fixture Can be used.

  In addition, in the above example, the drain water supplied from the air compressor 2 or the dehumidifier 3 is separated as drain water to be treated in the present invention, but the present invention is not limited to this. For example, the drain water (condensation water) generated in the compressed air supply pipe 4a between the air compressor 2 and the dehumidifier 3 and the compressed air supply pipe 4b between the dehumidifier 3 and the supply target is separated. It is possible to adopt a configuration in which the drain water supply pipe 5a is connected so as to be supplied to the compressed air dehumidification systems S1A and S1B.
