When we use the pipeline to transport the media, if there is liquid water in the media, will accelerate the corrosion of the pipeline; if there is solid impurities in the media, will cause the pipeline, equipment, Impurities in these media will not only reduce the transport efficiency of the pipeline, damage the life of the equipment, serious accidents can occur.
The appearance of the Big Oil Expeller is a good solution to the problem. The Big Oil Expeller can remove the solid and liquid impurities suspended in the medium, reduce the transport load of the pipeline and equipment, reduce the occurrence of corrosion and clogging, and ensure the safe and reliable operation of the pipeline and equipment. Of course, there are some Big Oil Expellers specifically designed to separate difficult to separate materials. Take a look!
Classified by function
Metering Big Oil Expeller: the main completion of the initial separation of oil and gas and measurement, generally a low-pressure Big Oil Expeller.
Production of Big Oil Expellers: the main completion of multi-mouth production wells focused on the initial separation of closed transport, is a high-pressure Big Oil Expeller.
2 by work principle classification
Gravity Big Oil Expeller: the use of liquid and gas, solid density of the different gravity to achieve the separation of different.
Tornado Big Oil Expeller: the use of liquid and gas, solid rotary motion by the centrifugal force to achieve the separation of different.
Filter Big Oil Expeller: the use of air flow channel filter elements or media to achieve separation.
Gravity Big Oil Expeller according to the function can be divided into two-phase separation (gas-liquid separation) and three-phase separation (oil and gas separation) two. According to the shape can be divided into vertical Big Oil Expeller, horizontal Big Oil Expeller and spherical Big Oil Expeller.
Separation principle: gas-liquid mixed fluid through the gas-liquid inlet into the Big Oil Expeller for basic phase separation, the gas into the gas channel for gravity sedimentation separation of droplets, liquid into the liquid space separation of bubbles and solid impurities, the gas before leaving the Big Oil Expeller The mist removes the small droplets and flows out of the outlet, and the liquid flows out of the outlet.
General Horizontal three - phase Big Oil Expeller
Separation principle: gas-liquid mixed fluid through the gas-liquid inlet into the Big Oil Expeller for basic phase separation, gas into the gas channel through the rectification and gravity settlement, separation of droplets; liquid into the liquid space to separate bubbles, while gravity conditions, the oil up Flow, water flow down to oil and water separation, the gas before leaving the Big Oil Expeller before the removal of small droplets by the fog from the outlet, the oil from the top through the overflow partition into the tank and from the oil outflow, water from the drainage Mouth outflow.
Gravity Big Oil Expeller type is many, but the basic structure is roughly the same, to vertical two-phase Big Oil Expeller as an example. By the shell, gas and water mixed imports, umbrella cap, export, sewage outfall, water bag, level gauge, partition separation, etc. formed. At the same time in order to make the Big Oil Expeller in the production process can be safe to run, the upper part is equipped with safety valve.
Primary separation section: the air inlet, the air into the cylinder, the air flow rate suddenly becomes low, into the stock of liquid or large droplets due to the role of gravity is separated directly into the liquid section, in order to improve the effect of primary separation , Often in the gas-liquid inlet at the entrance of the entrance near the water baffle or tangent approach.
Secondary separation section: The subsidence section, after the primary separation, carries the smaller droplets to the airflow outlet at a lower flow rate. At this point due to the role of gravity, the droplets are down and the separation of air separation.
The defogging section is mainly set in front of the gas flow outlet, which is used to trap smaller droplets (10-100um) that can not be separated from the subsidence section. Tiny droplets occur in this collision, agglomeration, and finally combined into larger droplets to sink to the effusion section.
Liquid section: the main collection of liquid. The general fluid section should also have sufficient volume to ensure that the gas dissolved in the liquid can be separated from the liquid and into the gas phase. The liquid discharge control system of the Big Oil Expeller is also the main content of the effluent section. In order to prevent the gas vortex when discharging, in addition to retaining a liquid seal, but also often in the drainage above the set of baffle class scraper
