Description

The present invention divides the inside of a condensing cylinder into which compressed air is introduced with a plurality of ventilation plates, and rationally realizes dehumidification and condensation of the compressed air in the divided space, and also makes it possible to efficiently dehumidify the compressed air. The present invention relates to a compressed air condensing device.

The compressed air discharged from an air compressor contains condensed water and oil, and if this compressed air is supplied to an air tool such as an air driver or impact wrench, the inside of the air pipe may rust or the components inside the air tool may rust. There is a risk that functionality may deteriorate and cause a malfunction.
For this reason, an air dryer is attached as a dehumidifying means to the compressed air supply pipeline to remove moisture, and the dehumidified and dried compressed air is supplied to the air tool (for example, see Patent Document 1).

However, since air dryers are expensive and complicated to install, the installation location and number of air dryers are restricted, making it difficult to sufficiently dehumidify compressed air.

Therefore, in order to solve the above problem, the applicant connected a plurality of tubular condensing units to a compressed air supply path, and each of the condensing units had a plurality of collision plates spaced apart inside the condensation unit. Compressed air is made to collide with a collision plate to condense it, and the compressed air is jetted out through the vents for adiabatic expansion, removing moisture from the compressed air and dehumidifying it. An air condensing device has been developed and has already been proposed (for example, see Patent Document 2).

However, the condensing device has a complicated structure, is difficult to manufacture, and is expensive.

In order to solve the above problem, the applicant constructed a condensing unit into a long tube using one or more joint tubes, arranged a plurality of collision plates at a distance therein, and proposed that the collision plates A compressed air system in which a large number of ventilation holes are formed in the air, and the compressed air collides with a collision plate to condense it, and the compressed air is jetted out from the ventilation holes for adiabatic expansion to remove moisture from the compressed air and dehumidify it. 10, 24, and 26 of the above-mentioned Patent Document 2.

However, in the condensing device, it takes time and effort to install the plurality of collision plates, and since the plurality of collision plates are arranged at approximately equal intervals, compressed air is introduced into the small space between the collision plates and dehumidified. There was a problem in that the ability to remove moisture from compressed air was generally low, and sufficient dehumidification accuracy could not be obtained.

Hereinafter, the present invention will be described with reference to the illustrated embodiments. In FIGS. 1 to 3, reference numeral 1 is an air compressor installed in a factory, etc., which stores the generated high-temperature, high-pressure compressed air in an air tank (not shown). A fixed amount of air is sent to a condensing cylinder 3 through an air conduit 2, and the compressed air, which has been dehumidified and dried in the condensing cylinder 3, is sent to a supply pipe 4 so that it can be supplied to an air tool 5 in a factory or the like.

The condensing cylinder 3 is formed into a slightly elongated straight pipe via a joint pipe (not shown), and a cooling cylinder 6 is disposed on the outside thereof.
The cooling cylinder 6 is composed of a long tube with a larger diameter than the condensing cylinder 3, and its lower end is set up on a base 7 such as the ground, and air is sucked in through air holes 8 provided at the lower end. The inner condensing cylinder 3 can be cooled by moving the inside of the cylinder upward.
The upper end of the cooling cylinder 6 is opened above the condensing cylinder 3, and the introduced air can be discharged to the outside through this opening 9.
That is, the cooling cylinder 6 has a chimney function, sucks air through the air hole 8 at the lower end, moves the cylinder upward, and exhausts heat-exchanged air from the upper end to the outside to cool the condensing cylinder 3. ing.

An air inlet pipe 10 and an air outlet pipe 11 are protruded in different directions from the upper end of the condensing cylinder 3 and are disposed on the outside. A supply pipe 4 is connected.
The other end of the air outlet pipe 11 is bent into an elbow shape and placed at the lower center of the condensing cylinder 3, so that dehumidified compressed air can be taken in from the opening at the lower end.

A plurality of collision plates 12 are arranged from the bottom to the middle of the condensing cylinder 3, and the inside of the condensing cylinder 3 is partitioned by the collision plates 12. That is, the total volume inside the condensing cylinder 3 is approximately determined by the inner diameter and the interval between the upper and lower ends of the inner surface, and the upper end of the inner surface and the upper collision plate 12 define the widest upper chamber Ro, and the lower end of the inner surface and the collision plate 12 at the lowest position define a lower chamber Ru, and the two upper and lower collision plates 12 define an intermediate chamber Rm. The volume of the intermediate chamber Rm is divided into upper and lower halves by the collision plate 12 at the intermediate position, and the facing interval d is formed to be the same.

The height of the upper chamber Ro from the upper surface of the collision plate 12 is approximately 5 d, the height of the lower chamber Ru from the lower surface of the collision plate 12 is approximately 1.5 d, and the height of the intermediate chamber Rm is approximately 5 d. is formed at 2d. Therefore, the volumes of each chamber are formed in a ratio of Ro:Rm:Ru of approximately 5:2:1.5, and can accommodate compressed air at this ratio.

A plurality of small-diameter ventilation holes 13 are formed in the collision plate 12, and compressed air is blown out from the ventilation holes 13 to enable adiabatic expansion. In the figure, reference numeral 14 denotes a drain wrap attached to the lower end of the condensing cylinder 3, which allows drain (not shown) accumulated at the lower end of the condensing cylinder 3 to be discharged to the outside.

The compressed air condensing device of the present invention configured in this manner requires the manufacture of the condensing cylinder 3 and the cooling cylinder 6. Among these, the condensing cylinder 3 is formed into an elongated straight tube made of steel using one or more joint pipes, and a plurality of collision plates 12 are arranged at predetermined intervals inside the condensing cylinder 3.

In the embodiment of FIG. 2, the three collision plates 12 are arranged slightly below the middle part of the condensing cylinder 3, and the intermediate chamber Rm is configured to be approximately 1/4 of the total volume inside the condensing cylinder 3, and the upper side An upper chamber Ro is disposed on the lower side, and a lower chamber Ru is disposed on the lower side. The volumes of each chamber Ro:Rm:Ru are formed to be 5:2:1.5, and the intermediate chamber Rm is divided into upper and lower halves by a collision plate 12 in the middle, and a plurality of ventilation holes 13 are provided in each collision plate 12. Form.

In this case, the volume distribution of each chamber Ro:Rm:Ru is divided based on the interval d between the collision plates 12, 12, and two collision plates 12, 12 are placed at the lower end of the air outlet pipe 11 in the condensing cylinder 3. An upper chamber Ro is formed above the upper collision plate 12 at a position approximately five times the facing distance d between the collision plates 12, and below the lowest collision plate 12, an upper chamber Ro is formed at a position approximately five times the facing distance d between the collision plates 12. A lower chamber Ru is formed at approximately 1.5 times the position.

The condensing tube 3 manufactured in this way is as shown in FIGS. 1 and 2, with an upper chamber Ro divided into a wide area at the upper part of the inside, an intermediate chamber Rm of less than half of the upper chamber Ro divided at the middle part, and an intermediate chamber Rm at the lowest position. A lower chamber Ru, which is slightly narrower than Rm, is defined.
Among these, the upper chamber Ro mainly functions to condense the introduced compressed air due to collision with the collision plate 12, and the intermediate chamber Rm functions to adiabatic expansion of the introduced compressed air from the ventilation hole 13, The lower chamber Ru functions to condense the introduced compressed air by collision with the curved bottom surface, and to cause adiabatic expansion from the vent hole 13.

The cooling cylinder 6 is formed into a long tube with a larger diameter than the condensing cylinder 3, and its lower end is erected on a base 7 such as the ground, and air is sucked in through air holes 8 provided at the lower end. This moves the inside of the cylinder upward, allowing the condensing cylinder 3 to be cooled. That is, the cooling cylinder 6 is equipped with a chimney function.

The condensing tube 3 is placed inside the cooling tube 6 thus manufactured, the condensing tube 3 is supported at the center of the cooling tube 6, and one end of the air conduit 10 connected to the condensing tube 3 is connected to an air tank (not shown). The air outlet pipe 2 of the air compressor 1 is communicated through the air outlet pipe 1, and the discharge side of the air outlet pipe 11 is communicated with the upstream side of the supply pipe 4.

When high-temperature, high-pressure compressed air generated by the air compressor 1 is introduced into the condensing cylinder 3 assembled in this way, the compressed air first flows into the upper chamber Ro, and a large amount of compressed air is introduced into this upper chamber Ro. .

In this case, since the condensing tube 3 is placed close to the air tank (not shown), the pressure of the compressed air decreases little, maintains a high pressure, flows into the upper chamber Ro, and hits the collision plate 12 at the top position with force. They collide well and condense. At this time, the compressed air collides with the collision plate 12 at high pressure, and the condensation occurs vigorously, and a large amount of condensed water is removed from the compressed air.
Moreover, the amount of compressed air in the upper chamber Ro corresponds to about 58% of the compressed air introduced into the condensing cylinder 3 per unit time, and since this compressed air is dehumidified and water vapor is removed, a large amount of the condensation occurs. It is done efficiently.

On the other hand, at the same time as the compressed air that has flowed into the upper chamber Ro is condensed, it is ejected downward from the vent hole 13 and expands adiabatically, and water vapor in the compressed air is liquefied and dehumidified.
In this case, in the adiabatic expansion, since the pressure in the upper chamber Ro is maintained at a high pressure as described above, the work of the compressed air is large, and this adiabatic expansion efficiently lowers the temperature and liquefies the air.

Next, the compressed air ejected downward from the vent hole 13 collides with the collision plate 12 at an intermediate position and is condensed.At the same time as this condensation, the compressed air ejects downward from the vent hole 13 and expands adiabatically, causing water vapor in the compressed air to Liquefied and dehumidified.
After that, the compressed air moves to the collision plate 12 at the lowest position, collides with it, and is condensed. At the same time, it jets out downward from the vent hole 13 and expands adiabatically, and the water vapor in the compressed air liquefies and dehumidifies it. be done.
Further, the compressed air jetted downward from the vent hole 13 collides with the curved bottom surface at the lower end of the condensing cylinder 3 and is condensed, and is urged to flow into the lower end of the air outlet pipe 11.

In this way, approximately 58% of the compressed air introduced into the condensing cylinder 3 flows into the upper chamber Ro, collides with the collision plate 12 directly below and is condensed, and water vapor is removed and dehumidified.
In addition, in the intermediate chamber Rm, about 23% of the compressed air introduced into the condensing cylinder 3 collides with the collision plates 12, 12, is condensed, blows out downward from the vent hole 13, and expands adiabatically. Through repeated adiabatic expansion, the water vapor in the compressed air is liquefied and dehumidified.

Furthermore, in the lower chamber Ru, approximately 19% of the compressed air introduced into the condensing cylinder 3 collides with the curved bottom surface of the lower end and is condensed, and also jets out downward from the vent hole 13 and expands adiabatically, causing the Water vapor is liquefied and dehumidified.

In this way, the compressed air blown into the lower chamber Ru is sufficiently dehumidified, and the dry compressed air is pushed into the opening at the lower end of the air outlet pipe 11, moves upward through the air outlet pipe 11, and passes through the opening at the upper end into the supply pipe. 4 and is supplied to the air tool 5.
The condensed water discharged from each of the rooms Ro, Rm, and Ru flows down inside the condensing cylinder 3 and is stored in the drain wrap 14 at the bottom.

During the dehumidification of compressed air by the condensing tube 3, air is sucked in from the lower ventilation hole 8 in the outer cooling tube 6, and this air moves between the cooling tube 6 and the condensing tube 3 due to the chimney effect. The outer periphery of the condensing cylinder 3 is cooled to promote condensation and adiabatic expansion, and is discharged to the outside through the opening 9 at the upper end.

In this way, the present invention rationally arranges a plurality of collision plates 12 in the condensation cylinder 3, rationally divides a plurality of compressed air introduction chambers Ro, Rm, Ru in the condensation cylinder 3, and Since compressed air is rationally introduced into the chambers Ro, Rm, and Ru for condensation and adiabatic expansion, compared to conventional condensing devices that dehumidify by arranging a plurality of collision plates at equal intervals in the condensing cylinder 3, Condensation and adiabatic expansion of compressed air can be performed rationally and efficiently.

At that time, for example, if the volume of the upper chamber Ro into which compressed air is introduced is made larger than the volume of the other compressed air introduction chambers, a large amount of high temperature and high pressure compressed air generated by the air compressor 1 can be transferred to the upper chamber Ro. It is possible to condense and adiabatically expand the compressed air rationally and efficiently, increase the amount of condensation, efficiently dehumidify the compressed air, and supply the dehumidified compressed air to the air tool.

4 to 9 show other embodiments of the present invention, and the same reference numerals are used for components corresponding to those of the previous embodiment. Of these, FIG. 4 shows a second embodiment of the present invention, in which the volumes of the upper chamber Ro and intermediate chamber Rm in the condensing cylinder 3 are changed, and their volume ratio is changed.

That is, the number of collision plates 12 is reduced from three to two, the lower boundary of the upper chamber Ro is moved downward, and the facing interval between the two collision plates 12 is reduced to 1/2d, so that the upper chamber Ro is moved downward. While increasing the volume, the volume of the intermediate chamber Rm is reduced accordingly.

With this configuration, the volume of the upper chamber Ro is increased to about 1.3 times that of the above-described embodiment, and is divided into about 75% of the volume inside the condensing cylinder 3, and the volume of the intermediate chamber Rm is increased to about 1.3 times that of the above-mentioned embodiment. It is reduced to about 1/4 of that in the embodiment, and is divided into about 6% of the volume inside the condensing cylinder 3.
Therefore, the amount of compressed air introduced into the upper chamber Ro increases approximately 1.3 times compared to the above embodiment, and most of it (approximately 75%) is condensed and dehumidified, and a small amount (approximately 75%) of it is condensed and dehumidified in the intermediate chamber Rm. About 19% of the compressed air is condensed and adiabatically expanded in the lower chamber Ru, and dry compressed air is supplied to the air tool 5. .

FIG. 5 shows a third embodiment of the present invention, in which the volumes of the upper chamber Ro and intermediate chamber Rm in the condensing cylinder 3 are further changed, and the volume ratio thereof in the condensing cylinder 3 is changed. There is.
That is, the number of collision plates 12 is reduced from two to one, the lower boundary of the upper chamber Ro is moved further downward, the volume of the upper chamber Ro in the condensing cylinder 3 is increased to approximately 82%, and the intermediate The chamber Rm is eliminated, and the volume inside the condensing cylinder 3 is substantially made up of the upper chamber Ro.

With this configuration, the volume of the upper chamber Ro is increased to approximately 1.4 times that of the first embodiment, and the volume of the intermediate chamber Rm partitioned by the collision plate 12 is configured to be zero. Therefore, the amount of compressed air introduced into the upper chamber Ro becomes the total amount of compressed air introduced into the condensing cylinder 3, and this compressed air collides with the collision plate 12 with force, is condensed, and flows downward from the ventilation hole 13. It blows out, expands adiabatically, and is dehumidified.

In addition, the pressure in the upper chamber Ro is maintained at a high pressure with only a slight drop in pressure from the air tank (not shown) and collides vigorously with the single collision plate 12, so the collision pressure is high and the condensation is efficiently and vigorously generated. A large amount of condensed water is removed from the compressed air.
Further, the compressed air is ejected downward from the vent hole 13 and is adiabatically expanded, and the work due to this adiabatic expansion is performed against the high pressure compressed air, so the temperature is efficiently lowered and liquefied due to this adiabatic expansion.

In the lower chamber Ru, approximately 19% of the compressed air introduced into the condensing cylinder 3 collides with the curved bottom surface of the lower end and is condensed, and is also jetted downward from the vent hole 13 and expands adiabatically, causing the Water vapor is liquefied and dehumidified.

In this way, the compressed air blown into the lower chamber Ru is sufficiently dehumidified, and the dry compressed air is pushed into the opening at the lower end of the air outlet pipe 11, moves upward through the air outlet pipe 11, and passes through the opening at the upper end into the supply pipe. 4 and is supplied to the air tool 5.
The condensed water discharged from each of the rooms Ro, Rm, and Ru flows down inside the condensing cylinder 3 and is stored in the drain wrap 14 at the bottom.

FIG. 6 shows a fourth embodiment of the present invention, in which one collision plate 12 is arranged directly above the collision plate 12 of the second embodiment, and these are used to vertically move a similar intermediate chamber Rm. The upper chamber Ro is arranged above this.
In this embodiment, the volume of the upper chamber Ro is formed to be approximately 1.3 times that of the first embodiment, and the intermediate chamber Rm partitioned by two collision plates 12 has a volume equal to that of the intermediate chamber Rm of the first embodiment. It is formed to 1/2 of the size.

The amount of compressed air introduced into the upper chamber Ro is approximately 1.3 times that of the first embodiment, and this compressed air collides vigorously with the collision plate 12 and is condensed, generating a large amount of condensed water. The amount of compressed air introduced into each intermediate chamber Rm is 1/2 that of the intermediate chamber Rm of the first embodiment, and a considerable amount of condensed water is removed overall.

FIG. 7 shows a fifth embodiment of the present invention, in which a collision plate 12 is arranged directly above the collision plate 12 of the first embodiment at an interval of d/2, and the collision plate 12 is introduced into the upper chamber Ro. The compressed air collides vigorously with the collision plate 12 at the uppermost position and is condensed.
Then, the compressed air is jetted downward from the vent hole 13 to be adiabatically expanded, and the jetted compressed air collides with the collision plate 12 directly below and is condensed. Thereafter, the jetted compressed air is jetted downward from the vent hole 13 to be adiabatically expanded, and the jetted compressed air collides with the collision plate 12 directly below and is condensed.

Further, the compressed air is ejected downward from the ventilation hole 13 of the collision plate 12 to adiabatically expand, and the ejected compressed air is caused to collide with the lowest collision plate 12 and condensed, and the compressed air is discharged from the ventilation hole 13. Air is ejected downward for adiabatic expansion.
In this way, the compressed air ejected into the lower chamber Ru collides with the curved bottom surface of the lower end and is condensed, and is ejected downward from the vent hole 13 and expands adiabatically, liquefying water vapor in the compressed air and dehumidifying it.
Then, the dry compressed air is forced into the opening at the lower end of the air outlet pipe 11, moves up the air outlet pipe 11, moves from the opening at the upper end to the supply pipe 4, and is supplied to the air tool 5.

In this way, the fifth embodiment increases the number of collision plates 12 compared to the first embodiment, so that compressed air is condensed by a plurality of collision plates 12, and compressed air is ejected downward from the vent holes 13 for adiabatic expansion. This increases the liquefaction of the water vapor in the compressed air, causing approximately 52% of the compressed air introduced into the condensing tube 3 to collide with the collision plate 12 at the top position and condense it, thereby increasing the liquefaction of the compressed air below the upper chamber Ro. It actively dehumidifies.

FIG. 8 shows a sixth embodiment of the present invention, in which collision plates 12 are arranged at an interval of 2d above the collision plate 12 at the uppermost position of the fifth embodiment, and directly above the collision plate 12. A pair of collision plates 12 are arranged one above the other with an interval of d/2.

Approximately 34% of the compressed air is then introduced into the upper chamber Ro, and it is introduced from above into a pair of intermediate chambers Rm with an interval of d/2, an intermediate chamber Rm with an interval of 2d, and a pair of intermediate chambers Rm with an interval of d/2 from above. The compressed air collides with the collision plate 12 and condenses in each chamber, and is ejected downward from the vent hole 13 for adiabatic expansion. Approximately 19% of the air is condensed by colliding with the curved bottom surface of the lower end, and is also jetted downward from the vent hole 13 for adiabatic expansion to liquefy water vapor in the compressed air and dehumidify it.

In this way, in this embodiment, approximately 34% of the compressed air is first condensed, and after the condensed water is removed, condensation and adiabatic expansion are repeated in each chamber to liquefy the water vapor in the compressed air, resulting in precise dehumidification. That's what I do.

FIG. 9 shows an applied form of the seventh embodiment of the present invention, in which the pair of intermediate chambers Rm with a d/2 spacing in the lower part in the seventh embodiment are deleted, and the pair of middle chambers Rm with a d/2 space in the upper part are removed. Approximately 34% of the compressed air introduced into the condensing cylinder 3 is introduced and condensed by leaving a pair of intermediate chambers Rm, and while the compressed air is condensed in the pair of intermediate chambers Rm, it flows downward from the vent hole 13. The compressed air is blown out and adiabatically expanded to expand the lower chamber Ru at the lowest position to approximately 53% of the interior of the condensing cylinder 3, and the compressed air introduced into the lower chamber Ru is forcefully collided with the curved bottom surface of the lower end and condensed. This condensation effect is doubled, and the water vapor in the compressed air is liquefied and dehumidified by being ejected downward from the vent hole 13 and adiabatically expanded.

The compressed air condensing device of the present invention divides the inside of the condensing cylinder into which compressed air is introduced with a plurality of ventilation plates, rationally realizes dehumidification and condensation of the compressed air in the divided space, and efficiently uses the compressed air. It is designed to be able to dehumidify.
