Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to an air separator for separating gas mixed in a liquid, and in particular to an air separator for separating gas mixed in a liquid. This invention relates to an air separator with good separation performance and simple structure.

0002

[Conventional technology]

Conventionally, various devices have been used to separate bubbles such as air mixed into liquid in piping lines. Although some ideas have been devised, the one shown in Figure 2 assumes that the liquid swirls inside the tank body. There is. Figure 2 is a longitudinal sectional view of the swirling flow air separator, showing the fluid inlet 1 and the fluid inlet 1. An outflow port 4 is provided in the connection direction of the cylindrical main body 2, and the inflow fluid is directed to the main body as shown by arrow A. The centrifugal force causes a cylindrical inner tube 3 made of a perforated plate to flow downward while rotating inside the body 2. A storage space in which air bubbles are moved inside and a liquid containing many air bubbles is formed at the bottom of the main body 2. The liquid is stored in the space 8, and when the liquid level in the inner cylinder 3 rises above a predetermined position, it is connected to the inside of the space 8. While discharging the liquid to a predetermined liquid level from the liquid discharge pipe 4 provided to pass through the liquid, , the liquid level in the inner cylinder 3 in the air chamber 5 formed in the upper part of the main body 2 is measured by a level meter Lc. It is discharged to the exhaust pipe 6 via the solenoid valve 7 which is electrically connected to the The degassed liquid is taken out from the outlet 4 on the lower side wall of the main body 2. be.

[Problem that the idea aims to solve]

This type of air separator has an inner cylinder 3 made of a perforated plate inside the main body 2. , due to fluctuations in flow rate, the fluid in the inner cylinder 3 containing many air bubbles after air separation will flow into the main body 2. There is a problem that the gas flows backward into the outlet 4 and is taken out, resulting in a decrease in degassing performance. In addition, the inlet 1 and outlet 4 are eccentrically provided at the upper and lower parts of the main body 2. This makes it difficult to connect piping lines. This proposal solves the above problems by efficiently separating air bubbles and The present invention provides an air separator that allows easy line connection.

0004

[Means to solve the problem]

The gist of this invention is to provide an inlet and an outlet that face each other on the upper side wall of a vertical cylindrical tank. The inside of the tank is divided into an inflow chamber and an outflow chamber by a guide pipe connected to the outflow port. The volume of the inflow chamber is made sufficiently larger than that of the outflow chamber, and the inlet of the guide pipe is connected to the entrance of the guide pipe. This is an air separator characterized by being installed at the bottom of the tank.

[0005]

[Effect]

Since the present invention has the above configuration, when water enters the tank from the inlet, the water flow rate is rapid. Due to the severe delay, air bubbles in the water are separated and rise to the top of the tank. Also If the inlet is installed eccentrically from the center of the tank, rotate it around the inner wall of the tank. The air bubbles in the water are separated and rise to the top of the tank. For this reason, the tank Only the liquid phase after separation is stored at the bottom of the tank, and the flow is carried out through a guide pipe with an inlet at the bottom. The liquid after air separation passes through the outlet chamber and is taken out from the outlet. In particular, the volume of the inflow chamber is sufficiently large compared to the outflow chamber in the tank, and it is connected to the outflow port. The gas phase is separated by a guide pipe that allows the The separation of the components is performed efficiently, and only the separated liquid phase component passes through the outflow chamber and flows out. It is taken out into the mouth. Furthermore, the gas phase after air separation will not be mixed in again.

【Example】

FIG. 1 is a sectional view showing one embodiment of the present invention, and 10 is a vertical type with a cylindrical cross section. The tank is provided with a valve 11 at the top for discharging gas, and a liquid flow at the top of the side wall. An outflow port 30 is provided at the same axial position facing the inlet 20 and the inflow port 20 . this When the inlet 20 is provided at a position offset from the center of the tank 10, the water flows into the tank. The liquid swirls in the tank 10 and air tends to be separated. Inside tank 10 The chamber is divided into an inflow chamber 50 and an outflow chamber 60 by a guide pipe 40 connected to the outflow port 30. The inflow chamber 50 has a sufficiently larger volume than the outflow chamber 60 of the guide pipe. In addition, a guide pipe 40 has an inlet in the lower part of the tank 10.

[0007] Therefore, the flow rate of the liquid flowing in from the inlet 20 is rapidly slowed down, and It flows downstream while swirling around the inner wall of the inflow chamber 50. This decrease in flow velocity and swirling of the liquid The gas phase in the liquid is separated and rises, remaining in the upper part of the tank 10 and becoming gas. It is discharged to the outside from the body discharge valve 11. The liquid phase is at the bottom of tank 10 as shown by arrow B. The liquid is taken out from the outlet 30 through the outlet chamber 60. At this time, the volume of the outflow chamber 60 is sufficiently small compared to the inlet chamber 50, so the flow rate of the liquid flowing in from the inlet 20 is large. Even if the temperature changes significantly, the gas phase component after separation is prevented from being mixed in, and only the gas phase component passes through the outflow chamber 60. Therefore, the separation performance is high. Furthermore, the inlet 20 and the outlet 30 are arranged to face the tank 10. Since they are located at the same axial position, piping workability is good.

[Effect of the idea]

As explained above, the air separator of the present invention has a simple structure, and even when the flow rate changes, it The separation performance of the body is stable, and the connection at the time of piping is easy.
