[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas for separating a liquid such as condensed water or condensed water mixed in a gas such as steam, compressed air or various gases into a casing by causing a swirling flow to separate the liquid by centrifugal force. It relates to a liquid separator.

2. Description of the Related Art In a conventional gas-liquid separator, swirling vanes are arranged in an annular space formed by a casing and an exhaust pipe, and the upper part of the annular space is connected to an inlet, and the upper part is passed through a hole inside the exhaust pipe. A swirl chamber is formed below the annular space, and a liquid reservoir is formed below the swirl chamber, and a lower end thereof is connected to the drain port, and a partition member is provided between the swirl chamber and the liquid reservoir. And a gap for liquid passage is formed between the outer peripheral edge of the partition member and the inner peripheral wall of the casing.
One example of this is disclosed in Japanese Patent Application Laid-Open No. 50-42467.

[0003]

In the above-mentioned conventional gas-liquid separator, depending on the speed of the flowing fluid,
That is, when the flow velocity is high, there is a problem that the minute liquid swirling from the center of the swirling chamber collides with the upper surface of the partition member, is re-engaged with the rebounding gas, and is carried out to the outlet.

Accordingly, it is an object of the present invention to prevent a minute liquid from being re-engaged in a gas and carried out to an outlet.

[0005]

Means for Solving the Problems In order to solve the above technical problem, the technical means of the present invention is to arrange a swirl vane in an annular space formed by a casing and an exhaust pipe, It is connected to the inlet, the upper part is connected to the outlet through the hole inside the exhaust pipe, and a swirl chamber is formed below the annular space and a liquid reservoir is formed below the swirl chamber, and the lower end of the liquid reservoir is drained. Connected to the opening, a partition member is arranged between the swirl chamber and the liquid storage chamber, and a gap for liquid passage is formed between the outer peripheral edge of the partition member and the inner peripheral wall of the casing. The gas-liquid separator is characterized in that an operation member is disposed so as to be displaceable up and down, a partition member is connected to the operation member, and the position of the partition member is vertically changed by operating the operation member from the outside.

[0006]

According to the above technical means of the present invention, when the flow velocity is high, the position of the partition member is adjusted downward, so that the flow velocity of the gas that collides with the upper surface of the partition member and rebounds is adjusted. Therefore, it is possible to prevent the minute liquid swirling from the center of the swirling chamber from being carried out to the outlet. If the flow rate is slow,
By adjusting the position of the partition member upward, the liquid storage chamber can be widened.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment showing a specific example of the above technical means will be described (see FIGS. 1 and 2). The casing is formed by welding the entrance member 2 and the bottom cover 3 to the main body 1 respectively. The entrance member 2 has an inlet 4 and an outlet 5 on the left and right sides. An inlet flange 6 is welded to the inlet 4 and an outlet flange 7 is welded to the outlet 5.
The bottom cover 3 has a drain port 8 at the center of the lower end, and a drain pipe 9 is welded to the drain port 8.

The main body 1 has a cylindrical shape and a diameter of an upper inner surface is increased. On the annular step between the upper inner surface and the lower inner surface of the main body 1, a double substantially cylindrical exhaust pipe 10 is mounted, and the exhaust pipe 10 is fixed between the inlet and outlet member 2. Exhaust pipe 10
The outer cylinder has a straight shape and is formed lower than the inner cylinder. The outer cylinder can be omitted and the main body 1 can be used as well. The inner cylinder of the exhaust pipe 10 has a shape in which an upper portion and a lower portion are gradually expanded. A swirl vane 12 is formed integrally with the exhaust pipe 10 in an annular space 11 formed between the inner and outer cylinders of the exhaust pipe 10.

The inlet 4 is connected to the lower annular space 11 through the communication hole 13, and the inside of the inner cylinder of the exhaust pipe 10 is connected to the upper outlet 5. A swirl chamber 14 is formed between the lower inner surface of the main body 1 and the inner surface of the bottom lid 3, and a liquid reservoir 15 is formed below the swirl chamber 14, and the lower end of the liquid reservoir 15 is connected to the drain port 8.

A plug 16 is screwed to the upper wall of the door member 2, and the operation member 2 penetrating through the door member 2 to the plug 16
0 is screwed. Nut part 21 at the upper end of operation member 20
To form Operation member 20, door member 2 and plug 1
A packing 22 for maintaining airtightness is interposed between the packing 22 and the packing 6.
The operating member 20 has a lower end extending to near the lower end of the main body 1, and a partition member 17 for separating the swirling chamber 14 and the liquid storage chamber 15 is fixed to the lower end with a nut 22. The partition member 17 has a disk shape and has four protrusions 18 on the outer periphery. Partition member 17 between protrusions 18
A liquid passage gap 19 is formed between the outer peripheral edge and the inner peripheral wall of the main body 1. The partition member 17 is vertically displaced by rotating the nut portion 21 to vertically displace the operation member 20.

When the flow rate of the inflowing fluid is high, the position of the partition member 17 is adjusted downward by rotating the nut portion 21, and when the flow rate is low, the position of the partition member 17 is adjusted upward. Adjust downward. The gas containing the liquid entered from the inlet 4 is swirled by the swirler 12. The liquid is swung outward and separated by the action of the centrifugal force, flows down along the inner peripheral wall of the main body 1, and flows into the liquid storage chamber 15 through the liquid passage gap 19 between the projections 18. The liquid that has flowed into the liquid storage chamber 15 is discharged from the liquid discharge port 8 to the outside of the system. The gas that has passed through the lower end of the exhaust pipe 10 flows out of the outlet 5 through the inside of the inner cylinder of the exhaust pipe 10. When the flow velocity is high, by adjusting the position of the partition member 17 downward, the flow velocity of the gas that collides with the upper surface of the partition member 17 and rebounds can be reduced. It is possible to prevent the small liquid that is being carried out to the outlet 5. When the flow rate is low, the position of the partition member 17 is adjusted upward, so that the liquid storage chamber 15 can be widened.

[0012]

As described above, according to the present invention, when the flow velocity is high, the position of the partition member is adjusted downward, so that the minute liquid swirling from the center of the swirling chamber can reach the outlet. It is possible to prevent the liquid from being carried out, and when the flow velocity is low, by adjusting the position of the partition member upward, an excellent effect that the liquid storage chamber can be widened is obtained.
