Description

Compressed Air Drying Equipment {Dryer for Compressed Air}

The present invention relates to a compressed air drying device that removes water, oil, and foreign matter contained in compressed air flowing through a compressed air pipe line, and particularly, inflow energy of compressed air without consuming additional power. The present invention relates to a compressed air drying apparatus capable of removing condensate, oil, and foreign matter by using centrifugal force.

In general, an air driving apparatus such as an air driver that performs work using compressed air includes a compressed air piping line for supplying the compressed air generated by the compressor to the air driving apparatus. However, the compressed air flowing along the compressed air pipe line includes condensed water, oil, and foreign substances generated during the operation of the compressor. That is, when the compressed air is made by using the compressor, moisture in the air is compressed together to generate condensed water, and part of the lubricating oil of the compressor is included in the compressed air as oil.

Such condensate, oil, and foreign matters must be removed in that they may cause malfunctions or breakdown of the air drive.

Accordingly, various methods for removing condensate and foreign substances contained in the compressed air flowing along the compressed air pipe line have been studied. In particular, as a method for removing condensed water, a method of cooling condensed water by cooling compressed air, a method of absorbing and removing condensed water by using an absorbent, and a method of removing condensed water by using an absorption filter are mainly used.

Refrigerated compressed air drying apparatus is a method of cooling the compressed air to remove condensed water, and is a device that freezes and removes condensed water in compressed air by cooling the compressed air by using a freezer. Since the electricity is continuously used for driving, there is a disadvantage that a lot of maintenance costs are required.

In addition, absorbent compressed air drying apparatus is a device that removes condensed water by using a moisture absorbent such as silica gel, but the moisture absorption efficiency decreases during long-term use. There is an expensive disadvantage.

In addition, the filter type compressed air drying apparatus is a device that removes condensed water and foreign matter by using an absorption filter, but has a disadvantage in that the filter is frequently replaced without high drying efficiency due to the characteristics of the absorption filter.

Each of the conventional compressed air drying apparatuses has advantages and disadvantages. However, except for the filter type compressed air drying apparatus, only condensate can be removed, but oil or foreign substances cannot be removed, and thus a separate process for removing them is required.

In other words, the conventional compressed air drying apparatus described above has a problem in that it is mostly to remove only moisture in the compressed air and is basically expensive and expensive to maintain.

Hereinafter, the compressed air drying apparatus of the present invention with reference to the accompanying drawings.

1 is a configuration diagram showing a compressed air drying apparatus according to the present invention, Figure 2 is a plan view of a compressed air drying apparatus of the present invention, Figure 3 is a configuration diagram showing another embodiment of the compressed air drying apparatus of the present invention 4 is a configuration diagram showing a modified example of the compressed air drying apparatus of the present invention.

Compressed air drying apparatus of the present invention, one or more dryers (10) for installing the compressed air by using a swirl flow and installed in the piping line to move the compressed air, respectively installed in the lower portion of the dryer (10) It is configured to include a drain portion 20 for discharging the condensed water discharged from (10).

The dryer 10 is provided with a drain hole 11 ′ in the lower center of the cone shape and is formed in a cylindrical shape with an upper surface sealed to be installed eccentrically on the main body 11 and the upper end of the side of the main body 11. And an inlet pipe 12 through which the compressed air introduced into the main body 11 flows along the inner surface of the main body 11, and an outlet pipe installed on the upper surface of the main body 11 to discharge the compressed air ( 13).

At this time, the inlet pipe 12 is installed in the form in which the inner surface of the outermost contact with the inner surface of the main body 11, it is preferable that the inclined downward on the side of the main body (11). Further, the main body 11 is more preferably formed in a structure in which the diameter decreases downwards. This facilitates the formation of the vortex of the compressed air and the formation of an air core at the center side.

In addition, the drain portion 20 is attached to the lower portion of the main body 11, the lower end is formed into a cone shape of the cylindrical drain body 21 and the condensate outlet 21 'and the drain body 21 The float 22 which rises and falls inside of the (), and the drain valve 23 is formed integrally with the float 22 to open and close the condensate outlet 21 ′.

Compressed air drying apparatus of the present invention configured as described above, by using the cyclone effect to remove the moisture, oil and foreign matter contained in the compressed air.

Compressed air flowing along the compressed air pipe line is introduced into the main body 110 through the inlet pipe 12. At this time, the outermost inner surface of the inlet pipe 12 is in contact with the inner surface of the main body 11. Therefore, the vortex is generated inside the main body 11 by the inflow energy of the compressed air introduced through the inlet pipe 12. Accordingly, the moisture, oil, and foreign matter contained in the compressed air are turned by centrifugal force. While being gathered on the inner wall of the main body 11 and flows down by gravity at the same time, the condensate mixed with water, oil and foreign matter is collected in the lower portion of the main body 11, the condensate is the main body ( It is discharged to the drain part 20 through the drain hole 11 'formed in the lower part of 11).

On the other hand, the compressed air turned into a vortex reversely rises at the bottom of the main body 11 to form an air core and is discharged through the outlet pipe 13 installed on the upper surface of the main body 11, It flows along the compressed air piping line. At this time, since the moisture, oil and foreign matter contained in the compressed air are separated and removed by centrifugal force in the dryer 10, the discharged compressed air is dried compared to the compressed air introduced.

In addition, the condensed water discharged to the drain portion 20 is collected at the lower portion of the drain body 21, and the float 22 rises as the amount of the condensed water increases. When the float 22 rises, the drain valve 23 integrally formed with the float 22 opens the condensate outlet 21 ′ provided in the lower portion of the drain body 21. Therefore, the condensed water of the drain body 21 is discharged to the outside through the condensate outlet 21 ′. When the condensate is discharged, the float 22 is lowered, and the drain valve 23 blocks the condensate outlet 21 ′. Thus, the inflow of foreign matter through the drain portion 20 is prevented.

On the other hand, by connecting a plurality of the dryer 10 may be repeatedly dried compressed air. That is, as shown in Figure 3, by connecting the plurality of dryers 10 in series by connecting the outlet pipe 13 of one dryer to the inlet pipe 12 of the other dryer by a connecting pipe 30, It is to repeat a process.

In this case, as the compressed air passes through each dryer 10, the humidity gradually decreases, thereby improving the drying rate of the compressed air. Finally, clean compressed air completely dried without moisture, oil, or foreign matter is compressed air piping line. It is supplied to the air drive through. Therefore, malfunction and failure of the air driving device due to moisture, oil, and foreign matter contained in the compressed air are not generated.

Up to now, the drain portion 20 has been described as being used only for the discharge of condensate, but by installing the inlet 24 into which the compressed air flows in the drain portion 20 as in the dryer 10. In addition, the cyclone effect may be used as an auxiliary dryer for predrying the compressed air supplied to the dryer 10.

That is, the compressed air introduced through the eccentrically installed inlet 24 rotates along the inner wall of the drain body 21 to form a swirl flow, and these compressed air are reversely elevated at the lower center thereof, so that the drain portion 20 It is to be discharged to the outlet 25 provided in the center of the top. In this case, the outlet 25 and the inlet pipe 12 of the dryer 10 are connected to each other so that the compressed air pre-dried in the drain 20 is introduced into the dryer 10 and dried again.

On the other hand, after the condensate generated in the dryer 10 flows along the inclined surface of the bottom, it is introduced into the drain portion 20 through the condensate discharge pipe 26 provided on one side. Then, the condensed water is discharged through the condensed water outlet 21 ′ together with the condensed water generated in the drain portion 20.

In the above description of the preferred embodiment of the present invention, the scope of the present invention is not limited only to this specific embodiment, those skilled in the art is appropriate within the scope described in the utility model registration claims of the present invention. It will be possible to change.
