Performance Testing Research Of Axial Dual Cylinder Gas-liquid Hydrocyclone Separator

With the development of petroleum industry, chemical, biological technology, the gas-liquid separation technology used more and more widely. Because of the simple and compact structure of the gas-liquid hydrocyclone separator, light weight, low energy consumption, especially suitable to use in advantages offshore oil &gas exploitation conveying, etc. Traditional guide vane gas-liquid hydrocyclone separator in handling volume and gas containing liquid concentration has some limitations. When entrance flow and contain liquid concentration is bigger, separation column section of liquid membrane attached on the wall thickness increases, return to mix increased smuggling phenomenon. Through the open fractures and in separator column section plus external tube, constitute a new structure gas-liquid hydrocyclone separator, namely axial dual cylinder gas-liquid hydrocyclone separator. Column section after open seams on the wall of the column section thickness of liquid membrane attached, effectively reduce return mix entrainment happens.In gas-liquid toroidal swirl separat wall cylinder body near liquid membrane layer seriously, entrainment high returns mix under the condition of low this problem separation efficiency in existing gas and liquid guide vane vortex separator basis, through the open in cylinder sleeve seam and adding outside the new structure design and performance tests. Based on the same condition original benchmark structure and the new structure of the separation of different open the performance test, the seam structure structure parameter and operating parameters optimization. Test results show that the separator is open seam structure of original structure can reduce existing return mix entrainment phenomenon, separation efficiency is increased obviously. Entrance flow and the applicable scope of the containing liquid concentration and expanded.
