In the filter separator is equipped with two different sets of different functions of the filter, coalescence filter and separation filter when the fuel flows through the filter separator, in its internal filtration, coalescence, sedimentation, separation of the four processes.
Jet fuel from the inlet into the filter first-level tray, and then dispersed into the first-stage coalescence filter, jet fuel from the inside out, first through the filter layer filter out solid impurities, and then through the coalescence layer, tiny water droplets Large water droplets, settling on the bottom of the filter, to achieve water separation; oil flow from the outside into the secondary separation filter, the future and the subsidence of the water droplets by the separation of the role of the red water in the jet fuel completely separated, settling in the sump, Drain valve discharge; clean jet fuel through the separation filter pool in the secondary tray. The purified jet fuel is fed from the filter outlet to the aircraft refueling system.
In accordance with the civil airport and military airport regulations: the use of oil depots to the aircraft wing under the fuel filler before the general use of three jet fuel filter separator device.
In the natural gas extraction process, both from the reservoir associated gas or from the gas zone of non-associated gas, generally contain liquid hydrocarbons, water and other liquid and cuttings, sediment and other solid substances, but also contains a small amount of non-hydrocarbon substances Of the mixed gas (mostly N2, H2S, CO2, organic sulfur and He, etc.). The presence and combination of these substances will cause the conveyor equipment, pipes, valves and other wear, corrosion, and even clogging, the transport system of measuring instruments, instruments and other adverse effects, pollution, desulfurization, dehydration solvent, affecting light hydrocarbon recovery The normal operation of the expansion turbine. Therefore, the dust and liquid in the natural gas must be removed by a horizontal filter separator before transport. Horizontal filter separators have been widely used in natural gas gathering and transportation station, natural gas purification plant.
Horizontal filter separator from the open blind plate, filter section, separation section, in addition to foam wire, liquid storage section and other components
The raw material gas from the gas pipeline first enters the filter section and filters the dust, a small amount of liquid and fog-entrained water through a filter tube (which removes 99% of the dust and 97% of the liquid) and then enters the separation section , The remaining dust and liquid are removed by gravity settling and de-foaming. Filtration and separation of dust and liquid through the connecting pipe into the storage section, and in the appropriate time to clean or discharged into the sewage treatment system.
As the filter tube needs to be cleaned and removed frequently, in order to shorten the demolition time and reduce the labor intensity of the front-line workers, the filter section should be set to open the blind plate at the end of the filter section. To avoid the short circuit of the gas, the partition should be set in the middle of the fluid section; Out of the dust, the end of the liquid storage section should be open type.
