Description

Technical Field

[0001] The utility model relates to the technical field of gas-liquid separation, in particular to a gas-liquid separator. Background Art

[0002] The gas-liquid separator adopts the principle of centrifugal separation and wire mesh filtration to achieve liquid removal. It is mainly composed of cylinder, cyclone separator, high-efficiency foam breaker, drain valve and other main components. The gas-liquid separator is widely used in chemical industry, natural gas, oil and gas extraction and other fields.

[0003] The foam breakers in the gas-liquid separator are divided into metal stainless steel materials and PP, PFTE, and plastic materials. In the chemical and oil and gas production processes, the foam breakers are easily corroded and damaged. During use, when the foam net is blocked, the separation efficiency will be reduced. At this time, the foam breakers need to be taken out for cleaning. After the blockage, the pressure in the separator increases rapidly, which is also easy to cause damage to the foam breakers, thus requiring replacement. The foam breakers in the existing gas-liquid separators are mostly fixed to the inner wall of the separator top pipe by bolts and nuts. When disassembling and assembling, the staff needs to use disassembly and assembly tools such as wrenches. When using a wrench to reach into the pipeline for operation, due to the weak light in the pipeline, it is inconvenient to align the wrench with the nut. Therefore, we need a new gas-liquid separator that is more convenient to disassemble, assemble and replace the foam breakers. Utility Model Content
