The disadvantage of this separator is the complexity of the design device, the insufficient efficiency of separation of air and vapors from a mixture with a high liquid content, as well as the occurrence of a rotating vortex of liquid above the outlet pipe, capturing the selected air.

The technical task of a useful model of a device for separating air and vapor from a liquid is to eliminate these drawbacks, expand and improve consumer properties.

1. A device for separating air and vapors from a liquid is proposed, comprising a cylindrical body, an air and vapor outlet pipe with a float shutoff valve, a transverse baffle with a gas pipe, a tangential liquid inlet pipe, a liquid outlet pipe from the device, and a drain pipe in which to increase the efficiency of separation of air and vapors from the liquid and eliminate the rotating vortex, a separating grating is installed in the lower part of the device above the outlet pipe.

2. The device for separating air and vapors from a liquid according to claim 1, in which the separating grate has an area of slotted openings not less than the passage area of the discharge outlet pipe.

Figure 1 shows a device for separating air and vapor from a liquid.

The device comprises a cylindrical body 1, an outlet pipe for air and vapor 2 with a float shutoff valve 3, a transverse baffle 4 with a gas pipe 5 located lower, a tangential pipe for fluid inlet 6, a separating grate 7, a pipe for fluid outlet 8, and a drainage pipe is installed at the bottom of the device 9.

A device for separating air and vapor from a liquid works as follows.

The liquid mixed with air and vapors enters the housing 1 through the tangential nozzle of the fluid inlet 6. Upon contact with the inner surface of the housing, the fluid acquires a circular motion in a spiral, pressing against the wall of the housing 1. Bubbles of air and vapor, having a lower specific gravity than liquid is collected inside the circular motion of the liquid and enters through the gas pipe 5 to the upper part of the device, in which the float valve 3 is mounted and there is an outlet pipe for air and vapors 2. As air accumulates in hen part of the housing 1, the liquid level drops. Together with the liquid, the float connected to the valve 3 is lowered. The valve opens, air and liquid vapors are vented through the pipe 2 into the outlet line. With the release of air and vapors, the liquid level in the housing 1 rises, and the float valve 3 closes the hole in the outlet pipe of the air and vapors 2.

The transverse partition 4 with the gas pipe 5 provides directional fluid swirling along the wall of the housing 1. The separating grid 7, located in the lower part of the housing 1 above the fluid outlet 8, is designed to intensify the separation of air bubbles and vapors from the liquid, which gradually accumulate on it surface into larger bubbles and float through the gas pipe 5 to the upper part of the housing 1.

The separating lattice is made in the form of a horizontal partition with a total area of slotted holes in it, not less than the cross-sectional area of the outlet pipe 8.

Additionally, the separating lattice 7 prevents the occurrence of a rotating vortex of liquid above the outlet pipe 8, which eliminates the capture of leaking air and vapors.
