Problems solved by technology

[0002] The existing gas-liquid separator has a large pressure drop and a large volume. The separation of gas and liquid in the gas-liquid two-phase flow is achieved solely by gravity or centrifugal force. The separation efficiency is low, and it is not suitable for the gas-liquid mixture with low dryness. Separation, and most separators can only realize the separation of gas and liquid, without the function of liquid discharge

Abstract

The invention relates to a gas-liquid separator with liquid-storing and liquid-discharging functions. The gas-liquid separator comprises a barrel, an arc-shaped liquid-separating pipe outside the barrel, and a cyclone separator, a streaming core body and a baffling liquid-separating plate which are arranged in the barrel, wherein the arc-shaped liquid-separating pipe is communicated with the barrel in a tangential direction of the outer side of the barrel; the streaming core body is arranged in the cyclone separator, an annular space is formed between the cyclone separator and the streaming core body, and the baffling liquid-separating plate is arranged on the outer side of the streaming core body in a sleeved manner. Compared with the prior art, the gas-liquid separator provided by the invention has the advantages that multiple separating manners such as the centrifugal force, the gravity and the surface tension are utilized in a comprehensive way, so that the multi-level separation of gas-liquid two-phase stream is realized, the separation efficiency is remarkably improved, and the size of the gas-liquid separator is reduced.

Description

technical field [0001] The invention relates to the fields of refrigeration air conditioners and heat pumps, in particular to a gas-liquid separator with liquid storage and liquid discharge functions. Background technique [0002] The existing gas-liquid separator has a large pressure drop and a large volume. The separation of gas and liquid in the gas-liquid two-phase flow is achieved solely by gravity or centrifugal force. The separation efficiency is low, and it is not suitable for the gas-liquid mixture with low dryness. Separation, and most separators can only realize the separation of gas and liquid, without the function of liquid discharge. In order to overcome the shortcomings of existing separators, reduce the volume of the separator, reduce the pressure drop of the separator, and improve the separation efficiency, a new structure is needed to meet these requirements. Contents of the invention [0003] The purpose of the present invention is to provide a comprehe...
