Description

Gas-liquid separator {GAS-LIQUID SEPARATOR}

The present invention relates to a gas-liquid separator for removing a liquid component such as water from a gas such as air, and particularly for improving the structure of a gas-liquid separator for centrifuging a liquid such as water from a gas such as air.

The gas-liquid separator as the subject of the present invention is essential in an environment for using sanitary equipment such as an air conditioner or a medical equipment that provides clean air as well as various mechanical devices that work through gas such as air. The reason is that the liquid components such as moisture contained in the gas such as air deteriorate the performance of various mechanical devices that work through the gas such as the air and corrode each part of the machine to shorten its lifespan, and in particular, adsorb foreign substances such as dust. This is because it provides a good habitat for microorganisms such as mold and contaminates the gas such as air.

Among the methods for removing liquid components such as moisture from gas such as air, centrifugal separation using a specific gravity difference between gas and liquid is well known. The centrifugal separation type is simpler in structure than the condensation cooling type using the refrigeration cycle, the absorption type using the solid adsorbent, the absorption type using the drying agent, the filter type, and the maintenance is easy.

The patent cited below relates to an oil separator which removes oil components from a refrigerant in a gas phase compressed in an air conditioner, and proposes the simplest structure of the centrifugal type. The oil separator consists of a cylindrical vessel and an inlet and outlet tube of refrigerant through which the refrigerant passes. The inlet pipe passes through a point close to the side wall portion away from its center at the top of the container and is curved to face the inner wall inside the container. The outlet pipe is in the form of a straight pipe passing through the center of the upper surface of the container. The compressed gaseous refrigerant introduced into the vessel through the inlet tube is ejected from the end of the inlet tube toward the inner wall of the vessel and flows in a vortex along the inner wall surface and moves through the centrally located outlet tube. As such, when the refrigerant flows in the vessel in a vortex form, an oil component having a larger specific gravity than the refrigerant in the gas phase is attached to the inner wall of the vessel by centrifugal force, and then flows down along the inner wall of the vessel by gravity to form the lower portion of the vessel. It is discharged to the outside through the discharge pipe.

Such centrifugal oil separators are useful for removing oil components from the refrigerant compressed into the gas phase, as well as for removing moisture from the compressed air.

One type of gas-liquid separator according to a preferred embodiment of the present invention is shown in FIGS. These drawings are merely examples for understanding the present invention, and some elements may be different from the actual items such as omitting or exaggerating.

Referring to FIG. 1, the gas-liquid separator of the present invention may be divided into a main body part 1 and a collecting part 2. The main body part 1 is connected to the pipes 3 and 4 separated on both sides by cutting off the middle of the external gas pipe line so that the gas passes through, and the liquid component is centrifuged from the gas therein. The centrifuged liquid component flows down by the gravity action and is collected in the collecting section 2.

Referring to FIG. 2, the components constituting the main body 1 include a main body 10, an upper cap 20, an elbow 30, a vortex forming tube 40, and an outlet tube 50. Parts corresponding to the above-mentioned collection part 2 include an intermediate cap 60, a collecting container 70, a holder 80 and a float valve 90.

The main body 10 has a cylindrical tube shape (not shown) surrounded by the inner wall 11 thereof, the upper end is processed by the male screw part 12, and the lower end is processed by the female screw part 13 ( 3).

The upper cap 20 has a female threaded portion 21 which tightly engages with the male threaded portion 12 of the upper end of the main body 10 (see FIG. 3), and closes the upper end of the space of the main body 10, and the two pipes The inlets 24 and outlets 25 of the gas connected to the connectors 22 and 23 and the connector are formed. The two piping connectors 22, 23 are dug in the transverse direction toward the center at each of the 180 ° opposite positions of the outer main surface (not shown) of the upper cap 20 so as to lie in a line in the transverse direction, and as described above, respectively. Both pipes 3 and 4 of the external pipe line can be connected on the same line. The inlet port 24 is formed in the longitudinal direction so as to communicate the space in the main body 10 with one side connector 22 in the transverse direction at a distance from the center, the outlet port 25 and the other connector 23 in the transverse direction The main body 10 is formed in the longitudinal direction to communicate the space at the center thereof.

The vortex forming tube 40 is screwed to the inlet 24 of the upper cap 20 through the elbow 30. The vortex forming tube 40 is shaped to substantially correspond to a portion of the threaded tube so as to eject the introduced gas obliquely from its end toward the inner wall 11 of the main body 10 (see FIG. 4).

The outlet 24 of the upper cap 20 described above is connected directly to the outlet guide tube 50 in the form of a screw. The outflow guide tube 50 is made of an appropriate length such that its end is preferably located slightly lower than the end of the vortex forming tube 40 described above (see FIG. 3). The outflow guide tube 50 may be integrally formed in the upper cap (20).

The intermediate cap 60 is a male screw portion 61, a blocking portion 62, which is tightly coupled to the male screw portion 13 of the lower end of the main body 10 described above, and a small diameter hole 63 drilled in the blocking portion 62. , The inner diameter portion 63 having a constant diameter below the blocking portion 62 and a fitted removable portion 64 inside the lower end portion. The blocking portion 62 is for preventing the loss of the gas passing through the space in the main body 10, and the hole 63 is for passing the liquid flowing down by centrifugation in the space. The blocking portion 62 is a preferred form that allows the liquid to flow easily without breaking the vortices of the gas passing through the space in the main body 10, and is formed in the shape of a partial surface of the convex downward.

The container 70 has an opening at its upper end and a discharge port 71 of liquid at the bottom thereof. The container 70 is made of a transparent or semi-transparent material as a preferred form so as to see through the inside, and the upper edge (not shown) is fitted in close contact with the inner diameter 63 of the intermediate cap 60 described above. I am supposed to lose.

The holder 80 is made of a high elastic material such as plastic so that the top edge (not shown) is resiliently fitted to the fitted detachable portion 64 of the above-described intermediate cap 60 in a state where the container 70 is accommodated so as not to be detached arbitrarily. It is coupled to hold the container (70), and has a vertically-sized see-through window (71) that can see around the inside of the container (70).

The float valve 90 is inserted into the container 70 and lowered by its own weight to block the outlet 71 of the container 70 at all times, and ascends according to the level of the collected liquid to open the outlet 71. .

In FIGS. 2 and 3, reference numerals 5 to 7, which are not described, are sealing rings interposed to maintain the airtightness of each part, and reference numeral 8 is fastened around the outlet 71 of the container 70, and thus the holder ( 80) is a nut that holds the coupling.

The gas-liquid separator carried out as shown in FIG. 3 is connected to the connectors 22 and 23 of the upper cap 20 in a straight state without the need to bend one pipe 3 and the other pipe 4 of the external gas pipe line. Can be installed. Therefore, the main body 10 is naturally maintained in a vertical posture. The gas flowing through the one side pipe (3) in this state is installed in the main body 10 from the end of the vortex forming tube 40 via the inlet 24, the elbow 30 and the vortex forming tube 40 in turn. Ejected into space. Referring to FIG. 4, since the vortex forming tube 40 is generally helical tubular, the gas ejected from its end is generally oblique with respect to the inner wall 11 of the main body 10 and has a downward angle corresponding to the pitch of the helical tube. Erupted while keeping The gas thus ejected eventually forms a vortex W which spirals along the inner wall 11. The vortex (W) of the gas reflects the blocking portion (62) of the intermediate cap (60) coupled to the lower end of the main body (10), and is changed to the air flow (A) that rises vertically at the center of low pressure and is installed at the center. The outflow guide pipe 50 is discharged to the other side pipe (4).

Centrifugal force acts on the gas moving in the vortex (W) form in the space in the body 10, the liquid component contained in the gas has a greater specific gravity than the gas, so the centrifugal force acting on the liquid component is larger. Due to this centrifugal force difference, the liquid component adheres to the inner wall surface 11 of the main body 10 and then flows down by the gravity action. Therefore, the gas in which the liquid component is centrifuged forms the vertical upward airflow A in the center portion.

The centrifuged liquid component passes through the hole (63) formed in the blocking portion (62) of the intermediate cap (60), falls to the container (70), and accumulates in the container (70). The float valve 90 is raised and naturally discharged to the outside through the discharge port 71. When the liquid is discharged and the water level is lowered, the float valve 90 descends again to block the outlet 71, so that the above-described gas is not lost through the outlet 71.

On the other hand, since the liquid level in the container 70 or the position of the float valve 90 is often checked through the see-through window 71 of the holder 80, if the float valve 90 malfunctions, the outlet 71 is always blocked or opened. You can confirm that you can, so you can take immediate action. In addition, it is possible to separate or repair or clean the container 70 through the check.

The present invention will be more variously possible in various forms in addition to the forms described above and illustrated in the drawings.
