Description

[Detailed Description of the Invention] The present invention relates to a gas-liquid separation device that separates liquid mist contained in gas.

First, a conventional device will be explained based on FIGS. 1 and 2.

When air containing liquid from the outer periphery of the cylindrical main body 1 is pumped from the inlet pipe 2 in the direction of the inner surface of the cylinder, the air containing the liquid is subjected to centrifugal force due to rotation, and the liquid with high density is transferred to the main body 1. is separated along the inner wall of the outlet section 4, while the less dense air is discharged from the outlet tube 3.

This device has the advantages of simple structure and low cost, but
This method has the drawbacks of low separation efficiency and the need to increase the size of the device in order to increase separation efficiency.

Therefore, the present invention was made with the purpose of eliminating the above-mentioned drawbacks, and the present invention has a wire mesh for condensation that extends below the lower end of the outlet pipe on the outer periphery of the outlet pipe inside the main body, and a wire mesh between the outlet pipe and the wire mesh. The present invention provides a gas-liquid separation device characterized in that a spiral member is provided.

Next, the present invention will be specifically explained based on an embodiment shown in FIGS. 3 and 4.

An inlet pipe 2 is provided on the outside of the cylindrical main body 1 and is provided toward the tangential direction of the inner surface of the main body 1.

An outlet pipe 3 is disposed at the top of the main body 1 so as to be directed downward from the outside to the inside of the main body 1.

The outside of the outlet pipe 3 inside the main body 1 is covered with a spiral band 6 and a wire mesh 5 for condensation.

The wire mesh 5 is located at a corner 5a where the ceiling 1b of the main body 1 and the outlet pipe 3 intersect.
Brazed with

The inner side 5c and outer side 5b of the spiral band are each brazed at their mating contact portions.

The wire mesh 5 and the spiral band 6 have a diameter of 1 to 1 of the diameter of the outlet pipe 3 than the outlet pipe 3.
It protrudes downward by 1.5@.

The winding direction of the spiral band 6 is adjusted to the direction of the swirling flow of gas and liquid.

The winding pitch of the spiral band is 1 to 2 times the diameter of the outlet pipe 3.

At the lowest part of the main body 1, there is a liquid outlet part 4.

When a mixed gas of air and liquid is pumped through the inlet pipe 2, a swirling flow is generated, and the liquid with a large diameter is subjected to centrifugal force and collides with the inner wall 1a of the main body 1, and then drips and is discharged from the outlet 4. Ru.

On the other hand, the liquid fraction with a small diameter has a small centrifugal force, so it swirls around the outlet pipe 3 and is condensed in the condensation wire mesh 5.
The liquid component with an increased diameter that naturally drips in the same direction as the swirling flow along the spiral band 6 and falls from the bottom of the spiral band 6 is again subjected to the centrifugal force of the swirling flow, collides with the inner wall 1a of the main body 1, and then drips to the outlet. Part 4
is discharged from.

The liquid adhering to the ceiling 1b inside the main body 1 is condensed into a wire mesh 5a.
Drips from.

Only the air from which the liquid content has been removed is discharged from the outlet pipe 3.

In conventional separation devices, liquids with small diameters were discharged from the outlet pipe 3 along with air without being separated due to the small centrifugal force, but in this device, liquids with small diameters are separated using a wire mesh 5 and a spiral band 6. It has an effect that can be done.

In addition, by protruding the wire mesh 5 and the spiral band 6 from the lower part of the outlet pipe 3, it has the effect of trapping and condensing the liquid that has flowed directly into the lower part of the outlet pipe 3, improving the separation efficiency and reducing the external shape of the device. can be made relatively small.

The present invention has been specifically explained above based on one embodiment.
The present invention is not limited to this embodiment,
For example, instead of the spiral band 6, the upper part of the main body with a circular cross section has an inlet pipe extending tangentially, the top of the main body has an outlet pipe extending from the inside to the outside, and the liquid is discharged to the lower part of the main body. In a gas-liquid separator having an outlet section, a wire mesh extending downward from a lower end of the outlet pipe is disposed around the outer periphery of the outlet pipe located inside the main body, and a spiral shape is formed between the wire mesh and the outlet pipe. According to the present invention, a liquid mist with a small diameter is captured by a wire mesh, and the diameter gradually increases, and the liquid mist is separated into a spiral member. Since the liquid mist with a small diameter can be reliably separated,
This has the advantage of increasing separation efficiency.

Furthermore, according to the present invention, since the spiral member is disposed between the wire mesh and the outlet pipe, in order to promote the agglomeration of the liquid mist, the spiral member is made of cotton cloth woven into a fine mesh with a small wire diameter. Even if a soft wire mesh is used, the wire mesh is reinforced by a spiral member, so even if it receives the pulsation of air that is pumped into the main body, the wire mesh will not deform or vibrate. It has the advantage of greatly improving the durability of.
