Description

Gas-liquid separator

Technical Field

The utility model relates to a gas-liquid separation field, in particular to vapour and liquid separator.

Background

In the refrigeration industry, the gas-liquid separation of the refrigerant has a great influence on the safety and efficiency of the system, such as a gas-liquid separator introduced at the suction end of a compressor and an economizer for improving the efficiency of the refrigeration system. Most of the existing gas-liquid separators are used for separating gas from liquid by means of sudden change of flow rate, and the effect is difficult to separate small liquid drops wrapped by gas. CN201710556492.6 patent proposes an economizer for gas-liquid separation, comprising a vessel having: a refrigerant inlet configured to allow the refrigerant in the gas-liquid two-phase state to flow therein and disposed on a side surface of the economizer, a gas refrigerant outlet configured to discharge the gas refrigerant after gas-liquid separation and disposed at an upper portion of the economizer, and a liquid refrigerant outlet configured to discharge the liquid refrigerant after gas-liquid separation and disposed at a lower portion of the economizer; a baffle plate that is disposed in the container at a position facing the refrigerant inlet, and that performs gas-liquid separation by colliding the gas-liquid two-phase refrigerant that has flowed into the container from the refrigerant inlet; and a demister disposed at a position facing the gas refrigerant outlet in the container and removing liquid droplets included in the gas refrigerant after the gas-liquid separation, wherein the baffle is formed of a partition plate extending in a vertical direction at a position between the refrigerant inlet and the demister to partition the refrigerant inlet side and the demister side, and a first opening for guiding the gas refrigerant after the gas-liquid separation and the liquid refrigerant to a space below the demister is provided between a lower end of the partition plate and a bottom of the container. The gas-liquid separator has a complex structure and is inconvenient to use. As another gas-liquid separation mode, aiming at the liquid drops with smaller diameters wrapped by gas, a porous filter screen is arranged at a gas suction port to filter and remove small liquid drops. This way of removing the droplets is complicated and it is difficult to avoid droplets not flowing into the suction pipe in case of a large suction port flow rate.

Detailed Description

The present invention will be described in detail with reference to the following embodiments and the accompanying drawings, wherein the described embodiments are only intended to facilitate the understanding of the present invention, and do not limit the present invention in any way.

The traditional gas-liquid separation is realized by suddenly reducing the flow velocity to enable liquid drops to sink under the action of gravity to play a role in separation, but the effect on the liquid drops with larger diameters is obvious, but the liquid drops with smaller diameters wrapped by gas are difficult to remove.

Referring to fig. 1, the gas-liquid separator provided in this embodiment includes a housing 1, a gas-liquid mixture inlet 2, a gas outlet 3, and a liquid outlet 4; liquid outlet 4 sets up the bottom of casing 1, gas outlet 3 sets up the top of casing 1, be provided with pipeline 5 on the gas-liquid mixture entry 2, the one end of pipeline 5 extends to in the casing 1 to be located below the liquid level 7, pipeline 5 with be located porous filter screen 6 in the casing 1 is connected or extends to inside porous filter screen 6. The porous filter screen 6 is wholly positioned below the liquid level 7. Further, the gas-liquid separator also comprises a suction pipe connected with the gas outlet 3. The housing 1 has a vertical oval structure or a horizontal oval structure. The small holes of the porous filter screen 6 are round holes, elliptical holes, square holes or irregular holes. The principle of the gas-liquid separator of the present embodiment is: the gas-liquid mixture enters a porous filter screen 6 below the liquid through a pipeline 5, and the gas escapes through small holes on the surface of the porous filter screen 6, wherein the process is a process of dispersing large bubbles into small bubbles and increasing the surface area of the gas. The escaped small bubbles gradually float upwards under the action of buoyancy, are broken at the liquid level 7 to release saturated gas in a corresponding pressure state, and then enter the air suction pipe connected with the air outlet 3 under the action of pressure difference.

The gas-liquid separator of the embodiment has the following technical effects that the outlet of the gas-liquid mixture is arranged below the liquid level 7, and the porous filter screen 6 is arranged at the outlet: liquid drops with large and small diameters coming out of the gas-liquid mixture are directly dissolved with the liquid phase; the gas is changed into very small bubbles after passing through the porous filter screen 6, the small bubbles are broken at the position separated from the liquid level 7 to release the gas, and the gas rises under the action of buoyancy and flows to the air suction pipe, so that the purpose of real gas-liquid separation is realized.
