Description

[Detailed explanation of the invention] The cyclone type drain separator for air compression is efficient and has a simple structure.The cyclone type has no particular problem when the capacity is extremely small, but as the capacity increases, the drain separator If you use a demister or perforated plate to prevent this, internal resistance will increase and clogging will occur. This resulted in various drawbacks, such as the need for frequent disassembly and cleaning.

In view of the above drawbacks, and as a result of various experiments, this idea was developed without the use of components that increase resistance, such as demisters and perforated plates, even if it is a cyclone method, and therefore does not require any troublesome maintenance such as cleaning. The purpose is to make it possible to accurately separate mist and air by changing the direction of air flow, and to make it efficient as a large-capacity drain separator and convenient to handle.

Referring to the drawings below, reference numeral 1 is a cylinder with an open upper end, a funnel-shaped part 2 at the lower part, and a drain pipe 3 connected to the lower part. 4 is a partition plate provided inside this cylinder 1. Reference numeral 5 denotes an inner cylinder installed in the cylinder 1 with its upper end attached to the partition plate 4, and this inner cylinder 5 introduces air containing liquid sent from a pressure tank or a compression section of a compressor between it and the cylinder 1. In addition, a large number of slits 7 are formed in the upper and lower zigzag positions on the entire circumference of the bottom of the inner cylinder 5, as shown in the exploded view of FIG. A communication hole 9 for pressure adjustment is provided in the center of the bottom plate 8 for pressure adjustment of the inner cylinder 5 provided near the upper end. Reference numeral 10 denotes an air discharge pipe with both upper and lower ends open, which is provided so as to penetrate tightly through the partition plate 4 from the upper chamber 11 which is open at the center of the cylinder 1 and enter the inner cylinder 5.
A socket 13 with an inverted bowl-shaped cap 12 is attached to its upper end, and a shielding plate 16 is fixed to its lower end with a mounting piece 14 inside the inner cylinder 5, leaving an appropriately sized ventilation gap 15 in the upper part. do. Reference numeral 17 denotes an inlet provided near the partition plate 4 for introducing compressed air containing liquid into the circumferential gap 6 in a tangential direction along the inner wall surface of the cylinder 1. As shown in FIG. Reference numeral 18 denotes a pressure regulating plate provided at the lower end of the funnel-shaped portion 2, that is, at the upper end of the drain pipe 3, and a passage 19 of an appropriate size is formed in the center thereof. A perforated plate 21 attached to the lower end of the drain pipe 3 is a drain outlet for discharging the drain on the partition plate 4, and is connected to a drain discharge pipe 22 as appropriate to discharge the drain to an appropriate location. 23 is a mounting seat for the vessel body.

Since this drain separator is constructed as described above, the compression part of the pressure tank or compressor is connected to the inlet 17 via a pipe, and compressed air is passed through the inlet 17 into the circumferential gap between the cylinder 1 and the inner cylinder 5. When the air is introduced tangentially into the cylinder 1, it circulates along the inner peripheral surface of the cylinder 1, and the liquid contained in the air is separated by the cyclone action, and the air further descends while circulating. Pass through the slit 7 formed at the hem of the inner cylinder 5 at a zig-sag position to change the direction.
At this time, the mist in the air is separated by changing the direction. In addition, a shield 16 is installed at the lower end of the air discharge pipe 10 so that the air from which the mist has been separated in this way does not attract mist again, and even if it does, it does not flow directly into the atmosphere from the air discharge pipe 10. A ventilation gap 15 opened to the surrounding area is provided by the mounting piece 14 so that the air can change direction and enter the air discharge pipe 10, and a cap 12 is provided at the upper end of the air discharge pipe 10. Since the air discharged from the upper end of the air discharge pipe 10 hits the cap 12 and is discharged after changing its direction in an N-shape, the mist of the discharged air is almost completely culled, and the air is discharged from the upper end of the air discharge pipe 10. The pressure balance with the drain pipe 3 is achieved by the size of the air gap 15 at the bottom of the discharge pipe 10, the bottom plate 8, and the communication hole 9 and the port 19 of the pressure adjustment plate 18, thus pressurized air is directly discharged. tube 1
In combination with the inner cylinder 5, which has a bottom plate 8 with slits 7 lined up at the hem so as not to come out from the bottom and a communication hole 9 in the center, and the bottom plate 8 for pressure adjustment, a hole 16 is formed in the center. Since the pressure adjustment plate 18 is provided to suppress the pressurized air, it also suppresses the attraction of mist.
The bottom plate 8 and the shield plate 16 are used to change the direction of air flow and to prevent air from flowing upward from the bottom.
As a result of separating the mist by colliding with air, the mist is discharged from the drain outlet 21 and the perforated plate 20 at the lower end of the drain pipe 3, making it suitable as a large-capacity drain separator. The structure is simple, and since it does not use any parts such as a demister, it does not require maintenance such as disassembly and cleaning, and is extremely effective in practice.
