A compressed air filter device having a structure in which the first and second filter means are arranged side by side in the vertical direction and are in communication with each other in the capture chamber is disclosed. In such a filter device, the compressed air is introduced into the trapping chamber from the introduction conduit through the first filter means, thereby condensing or vaporizing the vapor or liquid fine particles present in the compressed air. While being separated from the compressed air, the compressed air separated from the vapor or liquid particles is guided from the trap chamber to the compressed air delivery line through the second filter means. Thus, the liquid particles remaining in the compressed air can be vaporized, and the vapor or liquid fine particles in the compressed air can be effectively reduced.

Surprisingly, when I actually tested it, it was revealed that the pressure loss was quite large. Further, this wound product has a problem that a gap is easily formed between the wound body and the inner surface of the cylindrical body forming the outer wall of the filter means, and particularly when the mesh body is tightly wound, Such a problem becomes remarkable. Then, as a result, there is a problem that the effect of removing the vapor and the liquid particles in the first filter means is reduced.

The right slanted lower filaments 66 having a predetermined thickness (for example, about 1 mmφ) are arranged so as to be parallel to each other and the right slanted lower filaments 66 having a predetermined thickness (for example, about 1 mmφ) are overlapped and positioned. The intersections are welded together and integrally joined and formed to form a rhombic mesh. In addition, the mesh 64
Has a thickness obtained by adding the thickness (wire diameter) of the lower wire 66 and the thickness (wire diameter) of the upper wire 68, and is formed to be thin and uniform throughout.

It can be easily formed into a size and shape corresponding to the inside of 2, and the filling property is extremely good. Therefore, the first filling 34
Can be housed in close contact with the inner peripheral surface of the cylindrical body 32, and thus a gap is not effectively formed between the cylindrical body 32 and the cylindrical body 32. In particular, when the synthetic resin forming the filaments 66, 68 is highly elastic such as polypropylene, the adhesion is further enhanced. Furthermore, when using such a first padding 34, the first filter 10 can be used in comparison with the case where a conventional structure made of a thread of metal fiber such as stainless steel is used as the first padding. The pressure loss of the compressed air that is passed can be effectively reduced.

However, by being covered with the base 18 via the packing 56, the trapping chamber 20 having a predetermined sealed volume is formed. In addition, in the base 18, a porous body 58 having a honeycomb structure is housed in the base 18 in a state where the honeycomb holes are vertically arranged, and the bottom has a liquid discharge port 60 penetrating the bottom wall. It is formed and a drain 62 is attached.

0) indicates that the first and second filters 10 and 12 are communication holes 50 and 5 of the box member 16 that constitutes the trap chamber 20.
2 on the outer surface of the wall surface provided with the communication holes 50, 52.
So that the openings of the first and second recesses 28 and 30 of the manifold 14 correspond to the first and second filters 10 and 12, respectively. In the arranged state, a plurality of bolts 22 extending through the manifold 14 are respectively screwed to bolt supporting portions 54 provided on the box member 16 of the capturing chamber 20 so as to be integrally connected. And
As a result, a fluid flow path through which the air supplied from the inlet 24 is sent out from the outlet 26 is formed in the filter device.

る。Therefore, in the filter device having such a structure, first, the compressed air supplied from the inlet 24 of the manifold 14 is introduced into the first filter 10 having a large flow cross-sectional area, When passing through the first filter 10, the vapor or liquid of water or oil contained in the compressed air is caused by the adiabatic expansion action and the circulation in the presence of the first filling 34. The particles will condense or coalesce into droplets. that time,
The first filling 34 adheres well to the inner peripheral surface of the cylindrical body 32,
Compressed air will not flow through the first filling 3 because no gap is formed.
It is designed to be able to pass through the gap in 4 without fail,
The condensation or coalescence action is effectively obtained.

る。The droplets (liquids) condensed or combined in the first filter 10 are carried into the trapping chamber 20 by the compressed air flowing therethrough or adhere to the first packing 34. .. Thus, the first filling 34
Then, as described above, each underline 6 of the mesh 64 is
Since a very large number of spiral flow paths 70 are formed by 6 and the respective upper filaments 68, the droplets adhering to the first filling material 34 quickly flow down along the spiral flow paths 70, It is designed to fall into the capture chamber 20.
Therefore, it is possible to prevent the droplets from staying in the first padding 34, maintain good air permeability at all times, and when using such a first padding 34, The pressure loss of the compressed air can be effectively reduced.

る。Furthermore, in the trapping chamber 20, the flow cross-sectional area (volume for air flow) of the first filter 1 is
From a point larger than 0, the condensation or coalescence of the vapor in the compressed air proceeds due to the adiabatic expansion action, and in addition,
The velocity of the inflowing compressed air is reduced, so that the liquid in droplet form carried on the compressed air flow is effectively separated and dropped on the bottom surface of the base 18 by gravity and centrifugal force. Then, the dropped droplets are sent into the porous body 58 housed inside the base 18, further combined with other droplets, guided to the discharge port 60, and externally through the drain 62. It is discharged. In addition, since substantial air movement is prevented in the porous body 58, re-evaporation of the captured liquid is substantially excluded.

The water and oil remaining in the compressed air as liquid particles due to the action of the swirling phenomenon of the air flow caused when passing through the second filler 44 of the second filter 12, It will be vaporized. Thus, the compressed air from which the liquid fine particles have been removed is supplied to the delivery pipe line through the delivery port 26 of the manifold 14.
